[0001] The present disclosure refers to dispensing of medication. More particularly, the
present disclosure refers to devices for the automatic dispensing of medication and
to apparatuses including, or that are configured to include, such devices.
BACKGROUND
[0002] The term medication is intended herein to include pills, capsules, tablets, caplets,
and variants thereof, containing pharmaceuticals or drugs in solid, liquid or any
other form, or any other substance used to diagnose, treat, cure or prevent a disease.
[0003] Management and dispensing of medication are typically difficult, time-consuming,
and risky. Patients who are prescribed a medication may forget taking a given dosage
or may take the wrong dosage of medication. If a patient does not follow a prescribed
treatment properly, medication is ineffective. Poor or non-adherence to a prescribed
medication regimen has become a serious problem which often leads to serious health
consequences, in particular when takings are performed in residential settings, and
when multiple medications with different dosing amounts and time schedules are required
for treatment. The problem is further aggravated in elderly patients, patients suffering
several conditions, mobility-impaired patients, persons living alone, etc. This may
result in serious side effects and, in general, worsening of the patient, which in
some cases may even lead to hospitalization.
[0004] As used herein, adherence refers to compliance with a prescribed therapy or treatment.
Adherence to treatment is defined by the World Health Organization as the extent to
which a patient's history of therapeutic drug-taking coincides with a given prescribed
treatment. Thus, treatment adherence may be considered as the degree to which a person's
behavior corresponds with agreed recommendations from a health care provider.
[0005] In order to ensure adherence to a prescribed medication regimen, devices have been
developed for automatic dispensing of a prescribed dose of medication to a patient
at scheduled times.
[0006] For example, document
WO2016141102 discloses a medication dispensing device that comprises a reservoir having pill receiving
slots. At least one dispensed pill is selectively dispensed from at least one slot
by a dispensing mechanism to an extendible tray.
[0007] US2019133888 discloses a medication management device comprising cartridge slots for receiving
a pill cartridge including pills, and an extractor mechanism with a pill extractor.
The medication management device determines a medication regimen based on patient
data and the pill extractor extract pills from the cartridge as required.
[0008] In such known devices, however, the medication is stored in a reservoir or a cartridge
for being sequentially delivered according to a predetermined schedule. Such devices
suffer from a disadvantage that access to the medication is allowed before being been
loaded in the reservoir or cartridge. The patient or another person can access the
reservoir or cartridge and change dosage by adding or removing pills so there is no
suitable protection for the medication before being administered. This could result
in serious consequences if the patient does not pay attention to the medication that
is being dispensed. In the best case scenario, this may lead to an increased risk
of non-adherence, e.g. in terms of under-dosage and over-dosage of the medication.
This disadvantage is highly significant in risk patient populations.
[0009] In an attempt to overcome this issue, other medication dispensing devices have been
proposed in the art where the reservoir or cartridge is sealed with a film prior to
the administration. For example,
US5564593 discloses an apparatus for dispensing medications at timed intervals. Said medication
dispensing apparatus comprises rotatably dose modules each including one or more medication
discs. Said medication discs are provided with a plurality of equally spaced cylindrical
apertures formed therethrough about the perimeter in each medication disc. The apertures
define compartments for containing a single dose of a medication. Film layers are
applied to both faces of the medication discs for sealing the apertures each containing
said single dose of a medication. In use, the film is pierced by an extractor mechanism
for releasing the medication contained in said apertures.
[0010] Such medication dispensing apparatus is intended to be operated by an operator in
a medical setting. Therefore, no matter how bulky and cumbersome the apparatus is.
A further disadvantage is derived from this apparatus that it is intended and configured
for merely dispensing an individual, single dose of a particular medication to a patient.
[0011] There thus remains a need for a simple, compact, and yet efficient device that can
be easily used by the patient herself/himself for administering medication while suitably
ensuring adherence to medication treatment regimens, even in treatments involving
different types of medication or multiple prescriptions, by always dispensing an appropriate
amount of medication at an appropriate time to a patient or a number of patients in
a safe way.
SUMMARY
[0012] A device for the automatic dispensing of medication is disclosed herein with which
the above needs are met and with which a number of significant advantages are achieved,
as it will be detailed below. The present device will hereinafter be referred to as
automatic medication dispensing device.
[0013] The present automatic medication dispensing device comprises a body intended for
containing a medication to be dispensed to at least one user, or patient, and in general
to at least one person receiving medical treatment or under health care.
[0014] The body of the automatic medication dispensing device may be made of a semi-rigid
material, preferably a durable plastic material, such as a thermoplastic polymer.
One example of a suitable thermoplastic polymer for the manufacturing of the body
of the automatic medication dispensing device is high-density polyethylene (HDPE).
HDPE is a preferred, but not the only, material which the body of the automatic medication
dispensing device may be made from, due to low cost, good vapor and moisture barrier
qualities, good chemical resistance, and because it is chemically inert. However,
the present disclosure is not by any means limited to this material. Many other similar
materials compatible with drug delivery, preferably materials accepted at recycling
facilities, can be used for making the body of the automatic medication dispensing
device.
[0015] The body of the present automatic medication dispensing device has at least one medication
receiving pocket. Such medication receiving pockets are configured as cavities suitably
sized and shaped for receiving therein at least one medication to be dispensed. Each
medication receiving pocket of the body may contain the same or different types of
medication. The medication contained in one medication receiving pocket may correspond
to one medication prescribed dosage or taking.
[0016] Thus, a prescribed medication is first loaded into one, a number, or all of the receiving
pockets of the body of the automatic medication dispensing device. Then, a foil cover
is attached, i.e. adhered, stuck, or bonded, to a surface of the body where the medication
receiving pockets are formed for covering said medication receiving pockets. As a
result, the medication receiving pockets formed in the body of the automatic medication
dispensing device are duly covered and sealed and the medication contained therein
is duly protected against external environment.
[0017] The foil cover may be made, for example, from aluminum. However, many other safe,
non-toxic, cold and heat resistant foil materials may be used as long as they provide
a foil having a consistent thickness and a suitable tensile strength for pharmaceutical
packaging, as well as good gas barrier properties and moisture resistance, preventing
bacteria and microorganisms from penetrating into the medication receiving pockets.
[0018] The present automatic medication dispensing device defined by the body and the foil
cover is thus configured as a blister or blister pack suitable for packaging medication
within said pockets or cavities formed in the body that are covered by the above mentioned
foil cover. Such blister may be a single-use or non-reusable element. Reusable blisters
are not ruled out if necessary.
[0019] In one non limiting example of the present dispensing device, the body may be provided
with twenty-eight individual medication receiving pockets. Other number of medication
receiving pockets is possible. In one example, when all of the medication receiving
pockets are loaded with the prescribed medication, up to one week including four daily
intakes, seven days a week, can be reliably and safely scheduled to be dispensed.
[0020] Each medication receiving pocket may be suitable for containing one or a plurality
of equal or different pills, such as of the order of five pills of the common type,
for example, in each receiving pocket. As stated above, the pills contained within
each receiving pocket may correspond to an individual intake to be delivered to a
patient.
[0021] The body of the present automatic medication dispensing device further comprises
a drive portion having a shape matching the shape of a driving means for driving the
body towards at least one dispensing position where a dispensing portion of the foil
cover corresponding to a medication receiving pocket can be cut. In one non-limiting
example, the drive portion may be a shaped recess, for example, a recess in the form
of a prism, suitable for receiving a matching shaped protrusion, for example in the
form of a matching prism, of a driving means in an automatic medication dispensing
device. Other examples are of course possible such as those where the drive portion
is a shaped protrusion, for example a protrusion in the form of a prism, suitable
for fitting into a matching recess, for example in the form of a prism, of a driving
means in an automatic medication dispensing device.
[0022] In one preferred example, the body is circular in shape and the drive portion of
the body is arranged so that the body is driven in rotation towards a dispensing position.
In such example where the body is circular, it may be preferred that the medication
receiving pockets are radially distributed in the body. Other body shapes and types
of movements are also possible as well as arrangement of the receiving pockets in
the body of the automatic medication dispensing device.
[0023] At least one blade guiding protrusion is provided in the body of the automatic medication
dispensing device. Said blade guiding protrusion is associated with each medication
receiving pocket. The blade guiding protrusion is configured for receiving and guiding
at least one cutting blade for cutting the dispensing portion of the foil cover for
dispensing medication out of the body.
[0024] It may be preferred that at least one medication receiving pocket of the body has
an inner surface, where the medication rests, that is inclined to a horizontal plane.
When the present automatic medication dispensing device is arranged to operate in
a vertical position, that is, perpendicular to the ground, during use, it is preferred
that said inner surface is at an angle to the ground, that is, not horizontal, so
as to allow medication to be properly dispensed sliding thereon out of the body by
gravity.
[0025] The term horizontal is intended herein to refer to something that is oriented horizontally,
that is, arranged at a placement in space that is parallel to the ground, that is,
at right angles to the vertical. The term vertical is intended herein to refer to
a placement in space that is perpendicular to a horizontal line.
[0026] At least one of the body and the foil cover may include printed information regarding
at least medication contained in the medication receiving pockets. Other printed information
that can be applied to at least one of the body and the foil cover may include patient
profiles, dose, frequency, and type of prescribed medication, etc.
[0027] An automatic apparatus for dispensing of medication configured for receiving the
above described automatic medication dispensing device is also disclosed herein. Also,
an automatic apparatus is disclosed herein for dispensing of medication, including
the automatic medication dispensing device described above for the automatic dispensing
of medication.
[0028] In both cases, the automatic medication dispensing apparatus comprises at least one
device receiving area that may be formed in or be part of a housing. In one preferred
example, the housing of the apparatus is designed to be placed in a vertical position
that is, perpendicular to the ground. Said device receiving area is configured for
receiving at least one of the above described automatic medication dispensing device.
In one preferred example, said device receiving area is configured for receiving the
automatic medication dispensing device in a vertical position. Other positions for
the automatic medication dispensing device in the apparatus are of course possible.
[0029] In both automatic apparatuses, cutting means are provided for cutting, tearing or
breaking the foil cover, specifically a dispensing portion thereof corresponding to
a medication receiving pocket of the body as described above. The cut dispensing portion
of the foil cover is properly sized and shaped for allowing medication to be dispensed,
e.g. by gravity, out of the body. The cutting means may include a first blade that
may be carried by a guiding carriage to move it along a first direction to make a
first cut in the foil cover. The cutting means may further include two second, spaced
apart blades configured to move along a second direction, different from the first
direction, along the blade guiding protrusion of the body of the automatic medication
dispensing device to make corresponding second cuts in the foil cover. The second
direction may be perpendicular to the first direction although other relative orientations,
and thus other cutting shapes, are not ruled out. The cutting means are thus configured
to perform a dual cut defined by the first and second cuts performed by the first
blade and the second blades, respectively, forming the dispensing portion of the foil
cover in the form of a shaped opening such as a U-shaped opening. Said opening is
so sized that the medication contained within the medication receiving pocket of the
body of the automatic medication dispensing device fall through a guiding channel
to be dispensed out of the body into a medication container such as a glass that may
have been placed by the user or patient at a lower portion of the automatic apparatus.
The medication may be thus dispensed by gravity due to the inclined inner surface
within the medication receiving pocket, in particular when the automatic medication
dispensing device is arranged vertical to the ground.
[0030] For positioning the automatic medication dispensing device at a desired position,
for example, at a given angular position, relative to the cutting means in order to
form the above mentioned opening through the foil cover, driving means are provided.
The driving means are configured for releasably coupling to the drive portion of the
body for driving the body towards said desired position. The desired position corresponds
to at least one dispensing position where a dispensing portion of the foil cover corresponding
to a medication receiving pocket of the body can be cut by said cutting means for
dispensing the medication contained therein. A foil cover cutting operation is repeated
for each selected intake of medication.
[0031] The present automatic apparatus for dispensing of medication may further include
one or more of the following sensors for controlling operation. Specifically, a device
loaded sensor may be provided for detecting if an automatic medication dispensing
device has been suitably loaded in the apparatus. Such device loaded sensor may be
also configured to detect if a door of the housing of the apparatus has been properly
closed once an automatic medication dispensing device has been loaded in the apparatus.
A medication container sensor may be also provided for detecting that a medication
container, such as a glass, as stated above, is present in a medication receiving
area located in a lower portion of the apparatus. Further, a first medication sensor
may be also provided for detecting that at least one medication, e.g. a pill, is present
in said medication container. Other sensors may be also envisaged such as a second
medication sensor for detecting medication present in the medication receiving pockets
of the body so as to warn the user when one, a number, or all of the medication receiving
pockets of the body are empty in order to replenish the automatic medication dispensing
device or that the automatic medication dispensing device should be replaced with
another if it is reusable.
[0032] The apparatus may further include a control unit for managing a medication dosage
profile so as to drive the automatic medication dispensing device accordingly. A SIM
card reader may be provided for receiving a SIM card inserted into a slot formed in
the housing. The SIM card is able to communicate with a remote device so as to receive
remote patient profile information that is handled by said control unit for operating
the automatic medication dispensing device accordingly. Display means may be also
provided for displaying information regarding detected conditions by the above mentioned
sensors.
[0033] The operation of the automatic apparatus for dispensing of medication described above
is as follows.
[0034] An automatic medication dispensing device whose medication receiving pockets have
been previously loaded by a doctor, medical practitioner, physician, pharmacist, caregiver,
or a family member with a personalized type and amount of medication, e. g. a prescribed
number of pills, required for each individual intake, is loaded in a vertical position
into said device receiving area in the interior of the apparatus. This is carried
out such that the driving portion of the body of the automatic medication dispensing
device fits a matching driving portion of the apparatus in a way that the former can
be driven by the latter, e.g. in rotation. The door of the apparatus housing is then
closed by the user. In some cases, said door of the housing may be locked by the user
if required once it is properly closed.
[0035] When a device loaded sensor in the apparatus detects that the automatic medication
dispensing device has been loaded in the apparatus and the door has been properly
closed, and when a medication container sensor detects that a medication container
is present in a medication receiving area of the apparatus, a scheduled dispensing
operation can begin.
[0036] A visual or sound signal is issued by the apparatus when it is time for taking the
medication warning or reminding the user to take the medication. This information
can be sent to another person such as a family member. Then, a start button, preferably
located at a top, accessible and visible central portion of the apparatus, e.g. at
central top portion thereof, is depressed by the user to start operation of the apparatus.
Actuation of the start button may involve unlocking the door in the apparatus housing
so that a device receiving area in the interior of the apparatus can be easily accessed
by the user to load the automatic medication dispensing device in the apparatus.
[0037] Then, the automatic medication dispensing device is driven, e.g. in rotation, coordinated
with the actuation of the cutting means of the apparatus as follows. More specifically,
in each dispensing operation, the automatic medication dispensing device is driven,
e.g. in rotation, towards a dispensing position, for example corresponding to a given
angular position of the dispensing device, where a target medicament receiving pocket
is positioned to coincide with, e.g. in close proximity to, the cutting means of the
apparatus. When this position has been reached, a dispensing portion of the foil cover
corresponding to a medication receiving pocket is cut such that an opening is formed
therein. Medication is thus caused to go out of the medication receiving pocket through
a guiding channel into the above mentioned medication container, for example a glass.
When the first medication sensor in the apparatus detects that a medication, e.g.
a pill, is present in the medication container, e.g. a glass, a medication dispensing
alarm may be issued to the user warning her/him to remove the medication container,
e.g. the glass, for taking the medication contained therein. When the medication has
been taken, the user brings the medication container back to the medication receiving
area of the apparatus for future intakes. The medication container could be replaced
with a new medication container if required.
[0038] After a predetermined period of time, the medication container sensor checks if a
medication container is in the medication receiving area of the apparatus. In case
a medication container is detected in the medication receiving area of the apparatus,
the first medication sensor checks for a second time if medication, e.g. at least
one pill, is present in the medication container, e.g. the glass. In case that medication,
e.g. at least one pill, is present in the medication container, e.g. the glass, for
a second time, a non-delivery alarm is issued warning the user about an incomplete
taking.
[0039] It is to be noted that, as described above, the present apparatus does not perform
loading of medication into the dispensing device, i.e. the blister, but dispensing
of medication in a safe and reliable manner, ensuring that correct types and amounts
of medication are dispensed at the right time and to the intended person, promoting
medication adherence, with medication dispensing operations being controlled remotely.
[0040] Prescribed intakes may be scheduled through a website or by a software application
accessible on any platform and by any suitable remote devices such as mobile smartphones
or tablets allowing treatment information to be shared with a corresponding care team.
Treatments or prescriptions for multiple profiles can be managed and tracked easily
and reliably.
[0041] For the above reason, the present apparatus is very simple in construction, structure,
and operation. The present apparatus is also very easy to use so that it can be operated
by any person without the intervention of an operator such as a doctor, medical practitioner,
physician, pharmacist, or caregiver. The above mentioned remote control of medication
dispensing operations allows dosages to be changed quickly, for example when new prescriptions
are required.
[0042] As stated above, in a preferred example, the housing of the apparatus is designed
to be placed in a vertical position that is, perpendicular to the ground. As a result,
the apparatus takes up very little space so that it is suitable for home use, for
example, such as in a kitchen. Furthermore, the housing of the apparatus is also designed
to have a compact appearance that reminds daily household appliances such as a coffee
machine, instead of a medical or robotic product as with prior art apparatuses. With
the present apparatus, the medication should be not be kept hidden from view anymore
as it is stored safely within the apparatus.

DETAILED DESCRIPTION OF ONE EXAMPLE
[0045] Figures 1 and 5-6 of the drawings show one non-limiting example of the present apparatus
100 for the automatic dispensing of medication. The apparatus for the automatic dispensing
of medication will be referred hereinafter to as automatic medication dispensing apparatus
100.
[0046] The automatic medication dispensing apparatus 100 in the example described herein
is provided with a device 10 for the automatic dispensing of medication as illustrated
in figure 5. The device for the automatic dispensing of medication will be referred
hereinafter to as blister 10. Figure 5 thus shows the blister 10 loaded in the automatic
medication dispensing apparatus 100. The blister 10 has been illustrated in isolation
in the detail figures 2 and 3 of the drawings.
[0047] In the example shown in the figures 1 and 5-6 of the drawings, the automatic medication
dispensing apparatus 100 comprises a compact housing 140 intended to be placed at
home in a vertical position, perpendicular to the ground, that is, arranged parallel
to a line which runs up and down the page in the drawings. Although the housing 140
of the apparatus 100 may appear inclined in figures 5 and 6 this is simply due to
the different perspective views in said figures. In fact, the apparatus 100 in the
example shown is arranged in vertical position, that is, upright.
[0048] The compactness and the vertical positioning of the housing 140 results in that the
automatic medication dispensing apparatus 100 takes up very little space so it is
well suited for home use such as for example to be placed in the kitchen.
[0049] Still referring to figures 1, 5 and 6 of the drawings, a blister receiving area 130
is defined within the housing 140 of the automatic medication dispensing apparatus
100, as shown in figures 5 and 6. Said blister receiving area 130 is sized and shaped
for receiving the blister 10 in a vertical position that is, perpendicular to the
ground, that is, in the position shown in figure 3.
[0050] The automatic medication dispensing apparatus 100 is illustrated in figure 1 with
the housing 140 closed by a door 125 to prevent access to the blister receiving area
130. In figures 5 and 6, the automatic medication dispensing apparatus 100 is illustrated
with the door 125 released from the housing 140 so as to show the blister receiving
area 130. In figure 5 the automatic medication dispensing apparatus 100 is illustrated
with the blister 10 loaded in the blister receiving area 130 while in figure 6 the
automatic medication dispensing apparatus 100 is illustrated with no blister 10 loaded
in the blister receiving area 130.
[0051] The automatic medication dispensing apparatus 100 has a lower base portion 160 with
a medication receiving area 120. The medication receiving area 120 is suitable for
receiving a glass 170, as shown in figure 5 of the drawings, for receiving dispensed
pills. The lower base portion 160 of the automatic medication dispensing apparatus
100, in this example, is provided with a light ring 165 for illuminating the medication
receiving area 120 and the glass 170 placed therein when the apparatus 100 is in use.
[0052] Driving means 150 are provided in the automatic medication dispensing apparatus 100
for driving the blister 10 in rotation. The driving means 150 comprise a cross-shaped
protrusion 155 as shown in figure 6 of the drawings. Said cross-shaped protrusion
155 is coupled to a gear train, not shown, associated with an electric motor, not
shown. The electric motor is powered by suitable DC or AC power source. A suitable
DC power source may be a battery or a rack of batteries that may be for example built-in
rechargeable batteries. A suitable DC power source may be the electrical grid by connecting
via a standard wall outlet. Examples where the electric motor is powered by combined
DC/AC power sources are also possible.
[0053] In use, a rotational movement of the electric motor is transmitted to the cross-shaped
protrusion 155 through the above mentioned gear train which rotates the blister 10
through the above mentioned drive portion 50 of its body 20 into a target angular
position within the dispensing apparatus 100.
[0054] The blister 10, shown in detail in figures 2 and 3 of the drawing, comprises a non-reusable
circular body 20 made of a light weight material featuring high strength, stiffness,
durability, permeability to gas, and resistance to moisture such as high-density polyethylene
(HDPE). The body 20 of the blister 10, in the example shown, has twenty-eight individual,
radially distributed medication receiving pockets 30. In this example, all the pockets
30 are configured in the same way as cavities suitably sized and shaped for receiving
therein fifteen pills to be dispensed. With the configuration shown in said figures
2 and 3, up to one week including four daily intakes, seven days a week, can be conveniently
scheduled for dispensing when the medication receiving pockets 30 are loaded with
prescribed pills.
[0055] In some cases, the pills contained within each medication receiving pocket 30 may
be different from one another in terms of size, shape, surface composition, colour,
etc. depending on the prescription in terms of amount of drug, concentration, formulation,
and on the manufacturer. In other cases, the pills contained within each medication
receiving pocket 30 may be all the same. In the present example, the pills contained
within each medication receiving pocket 30 correspond to an individual prescribed
intake to be delivered to a patient.
[0056] The medication receiving pockets 30 in the body 20 of the blister are covered by
a foil cover 40, as shown in figures 2 and 3. The foil cover 40 in this non-limiting
example is an aluminium foil that is bonded, e.g. heat-sealed or glued, on to a back
surface of the body 20 where an outlet opening of each medication receiving pocket
30 is formed, corresponding to a back surface of the body 20 according to figure 3.
Bonding of the foil cover 40 on the body 20 of the blister may be performed for example
through a heat seal primer and a heat seal lacquer coating applied on the foil cover
40. This is carried out after the required medication receiving pockets 30 have been
duly loaded with the prescribed pills. However, the foil cover 40 may be made of any
other material than aluminium, as long as it can act a sealing sheet for protecting
the pills contained in the medication receiving pockets 30 and, that at the same time
can be easily cut by blades of a cutting means 110 in the automatic medication dispensing
apparatus 100 allowing easy dispensing of the prescribed pills by a simple cutting
action as it will be described below.
[0057] The body 20 and the foil cover 40 of the blister 10 both include printed information
about the medication that is contained therein, and about patient profiles, dose,
frequency, and type of prescribed medication.
[0058] The body 20 of the blister 10 includes a drive portion 50 as shown in figures 2 and
3 of the drawings. The drive portion 50 of the blister 10 comprises a cross-shaped
recess 55 that is formed extending into the back surface of the body 20, as shown
in figures 2 and 3, to protrude from the front surface of the body 20, in the same
way as the medication receiving pockets 30. The cross-shaped recess 55 of the drive
portion 50 of the body 20 is conveniently sized for releasably receiving a matching
cross-shaped protrusion 155 of the above mentioned driving means 150 of the automatic
medication dispensing apparatus 100 that is shown in figure 6 of the drawings. In
use, the drive portion 50 of the blister 10 is releasably coupled to the driving means
150 of the automatic medication dispensing apparatus 100 such that the blister 10
can be driven in rotation around a horizontal axis x as shown in figure 5. As used
herein, rotation around an axis refers to rotation of at least 360 degrees around
the axis. Rotation of the blister 10 is performed until the above mentioned target
angular position has been reached. Said target angular position relates to a dispensing
position of the foil cover 40 corresponding to a medication receiving pocket 30.
[0059] Still referring to figures 2 and 3 of the drawings, each medication receiving pocket
30 of the body 20 of the blister 10 has one blade guiding recess 32 associated therewith.
Each blade guiding recess 32 is arranged next to each medication receiving pocket
30 and is configured for receiving and guiding second, spaced apart blades 112, 113
of the above mentioned cutting means 110 of the automatic medication dispensing apparatus
100. Blades 112, 113 are intended to cut the foil cover 40 for dispensing the pills
out of the body 20 of the blister 10 into a glass 170 placed in the medication receiving
area 120 of the automatic medication dispensing apparatus 100 as shown in figure 5.
[0060] As also shown in figures 2 and 3 of the drawings, each medication receiving pocket
30 of the body 20 has an inclined inner surface 35 formed therein onto which the pills
rest within the pocket 30. Said inner surface 35 is inclined at an angle relative
to a horizontal plane, that is, at an angle relative to the ground. The angle of inclination
of the inner surface 35 in each medication receiving pocket 30 is suitable for dispensing
the pills contained therein out of the body 20 of the blister 10 by gravity into the
glass 170 placed in the medication receiving area 120 of the automatic medication
dispensing apparatus 100.
[0061] As stated above, the present automatic medication dispensing apparatus 100 includes
cutting means 110, which have been illustrated in detail in figure 4 of the drawings.
The cutting means 110 in the non-limiting example shown comprise a first blade 111
and the above mentioned second, spaced apart blades 112, 113. The second, spaced apart
blades 112, 113 are arranged parallel to each side of the first blade 111. The first
blade 111 is carried by a guiding carriage 114.
[0062] The guiding carriage 114 is configured to move the first blade 111 along a first
direction D1 to make a first cut in the foil cover 40 of the blister 10. The first
direction D1 is horizontal, that is, a direction parallel to the ground or to the
lower base portion 160 of the apparatus 100.
[0063] The second, spaced apart blades 112, 113 are configured to move along a second direction
D2. The second direction D2 is vertical, that is, perpendicular to the first direction
D1, that is, a direction parallel the length of the housing 140 or to a line which
runs up and down the page in the drawings. Other directions for the movement of the
blades 111, 112, 113 are possible. As stated above, the second blades 112, 113 are
configured to be driven along the blade guiding recess 32 formed in the body 20 of
the blister 10 to make corresponding second lateral cuts in the foil cover 40. Each
blade guiding recess 32 guides the movement of the second blades 112, 113 along said
second direction D2 avoiding the pills from being contacted by the blades 112, 113.
This helps prevent the pills from being broken up or at least contaminated by the
blades 112, 113.
[0064] The first and second cuts made by the blades 111, 112, 113 of the cutting means 110
define a U-shaped opening in a dispensing portion in the foil cover 40 so that the
pills contained within the medication receiving pockets 30 of the blister 10 can be
dispensed therethrough by gravity. The cutting operation is repeated for each selected
intake of medication.
[0065] A blister loading sensor, not shown, is provided in the automatic medication dispensing
apparatus 100 for detecting if the blister 10 has been loaded in the blister receiving
area 130 of the housing 140 in the automatic medication dispensing apparatus 100.
Said blister loading sensor is also suitable for detecting if the door 125 is properly
closed and locked before operation. A medication container sensor, not shown, is also
included in the present automatic medication dispensing apparatus 100 for detecting
that a glass 170 is present in the medication receiving area 120. A first medication
sensor, not shown, is also provided for detecting that at least one pill is present
in the glass 170. Furthermore, the automatic medication dispensing apparatus 100 further
includes a second medication sensor, not shown, for detecting pills in the medication
receiving pockets 30 of the blister 10. The second medication sensor is configured
to warn the user when one, a number, or all of the medication receiving pockets 30
are empty such that the blister 10 should be replenished with pills or that it should
be replaced with a new blister 10 as required.
[0066] A control unit, not shown, is also provided. The control unit is configured to manage
a medication dosage profile so as to drive the blister 10 in rotation accordingly.
The control unit can be remotely controlled via a SIM card configured to communicate
with a remote device. The automatic medication dispensing apparatus 100 further includes
an LCD display, not shown, for displaying information to the user about the operation
of the apparatus 100. The dispensing apparatus 100 may be configured to be remotely
controlled over Bluetooth or Wi-Fi if required.
[0067] Operation of the dispensing apparatus 100 is as follows. A blister 10 is provided
in which one, a number, or all of the medication receiving pockets 30 of the blister
10 have been properly loaded by a doctor, medical practitioner, physician, pharmacist,
caregiver, or a family member with a personalized and prescribed type and number of
pills that are required for each individual intake. This involves loading of medication
receiving pockets 30 with prescribed pills and then bonding a foil cover 40 on the
body 20 of the blister 10.
[0068] The user then unlocks the door 125 of the automatic medication dispensing apparatus
100 by pushing a door locking button 126 arranged at a lower portion of the housing
140 as shown in figures 1, 5 and 6, and mechanically connected to a door locking element
127 arranged at a lower portion within the housing 140 of the apparatus 100 as shown
in figures 5 and 6. As the door locking button 126 is pressed downwards, the door
locking element 127 is moved downwards against a spring, not shown, to release the
door 125 so that it can be opened or closed. The door 125 is hinged to the housing
140 of the apparatus 100 through a hinge 128 that is located at a side portion 141
of the housing 140 of the apparatus 100 as shown in figures 5 and 6.
[0069] As a result of releasing of the door 125, the apparatus 100 remains as depicted in
figure 6, with the door 125 open or released from the apparatus 100 and with the blister
10 still not loaded into the blister receiving area 130.
[0070] The blister 10 can be then loaded into the blister receiving area 120 in the interior
of the housing 140 of the automatic medication dispensing apparatus 100 in a vertical
position as illustrated in figure 5. When the blister 10 is loaded in the blister
receiving area 120 of the apparatus 100, the cross-shaped protrusion 155 of the driving
means 150 of the apparatus 100 is releasably coupled to the cross-shaped recess 55
of the body 20 of the blister 10, that is, the protrusion 155 of the driving means
150 of the apparatus 100 is received into the the recess 55 of the body 20 of the
blister 10.
[0071] The door 125 of the automatic medication dispensing apparatus 100 is then closed
by the user until it is locked due to the above mentioned spring that biases the door
locking element 127 into a door locking condition. The apparatus 100 at this point
remains as shown in figure 1, that is, with the blister 10 loaded in the blister receiving
area 120 of the apparatus 100 and with the door 125 safely closed in place.
[0072] A visual or sound signal is then issued by the apparatus 100 warning or reminding
the user that it is time for taking the prescribed pill(s). This information can be
sent to another person such as a family member where deemed appropriate.
[0073] The user now or previously places a glass 170, whether containing water or the like
or not, in the medication receiving area 120, as shown in figure 5 of the drawings.
[0074] The user then depresses a start button 180 located at a top portion 142 of the housing
140 of the automatic medication dispensing apparatus 100. In some cases, operation
of the start button 180 could allow actuation of the door locking element 127 so as
to unlock the door 125 as described above so that the blister receiving area 120 can
be accessed by the user to load the blister 10 into the apparatus 100.
[0075] When a blister 10 is detected by the above mentioned blister loading sensor to be
loaded in the automatic medication dispensing apparatus 100 and when the door 125
is detected to be properly closed and locked by the blister loading sensor, and also
when a glass 170 is detected by the medication container sensor to be present in the
medication receiving area 120 of the apparatus 100, a dispensing operation starts.
[0076] Operation of the automatic medication dispensing apparatus 100 is indicated by a
status light ring 181 that is arranged surrounding the above mentioned start button
180 in the top portion 142 of the housing 140 of the apparatus 100.
[0077] As the information about the prescribed intake has been processed by the control
unit, the blister 10 is then driven in rotation by the driving means 150 of the automatic
medication dispensing apparatus 100 in a required direction of rotation around axis
x towards a dispensing position. The dispensing position is where a dispensing portion
of the foil cover 40 corresponding to a target medicament receiving pocket 30 coincides
with the blades 111, 112, 113 of the cutting means 110 of the apparatus 100. When
a target dispensing position has been reached, said dispensing portion of the foil
cover 40 corresponding to a medication receiving pocket 30 is properly cut by the
blades 111, 112, 113 resulting in a U-shaped opening formed in the foil cover 40 through
which the pills can to go out of each medication receiving pocket 30 sliding onto
the inclined inner surface 35 of the pockets 30 and through a guiding channel into
the glass 170 that is placed in the medication receiving area 120 of the automatic
medication dispensing apparatus 100.
[0078] When a pill is detected by the first medication sensor, not shown, of the apparatus
100 to be present in the glass 170, a dispensing alarm is issued to the user. The
user then removes the glass 170 from the medication receiving area 120 of the apparatus
100 and takes the pill(s) contained in the glass 170. The user finally brings the
glass 170, back to the medication receiving area 120 of the automatic medication dispensing
apparatus 100 or replaces it with a new glass 170 in said medication receiving area
120 if required, for future intakes.
[0079] The medication container sensor checks, after a predetermined period of time, if
a glass 170 is in the medication receiving area 120 of the automatic medication dispensing
apparatus 100. When a glass 170 is detected to be present in the medication receiving
area 120 of the dispensing apparatus 100, the first medication sensor checks for a
second time if at least one pill is present in the glass 170. In case that at least
one pill is detected in the glass 10 for a second time, a non-delivery alarm is issued
warning the user about an incomplete taking.
[0080] The above is repeated for each dispensing operation.
[0081] A number of examples have been disclosed herein. However, many other alternatives,
modifications, uses and/or equivalents thereof are possible.
[0082] For example, although the present automatic medication dispensing apparatus has been
described with a blister receiving area configured for receiving the blister in a
vertical position, i.e. such that it is driven in rotation around a horizontal axis,
the automatic medication dispensing apparatus may be also configured to operate the
blister in other position than vertical such as horizontal, i.e. such that it is driven
in rotation around a vertical axis. In any case, the blister can be driven in rotation
in different directions of rotation as required. For example, a dispensing operation
according to a selected intake of medication may involve the blister being driven
in rotation in one direction of rotation. However, it may be the case that a dispensing
operation according to a selected intake of medication involves the blister being
driven in rotation according to a number of different directions of rotation.
[0083] On the other hand, although the automatic medication dispensing apparatus has been
described as having one or more blister receiving areas formed being part of a vertical
housing, other different positions from vertical such as horizontal are not ruled
out.
[0084] Also, although the blister has been described as having a drive portion comprising
a shaped recess suitable for receiving a matching protrusion of a driving means in
the dispensing apparatus, examples where the drive portion is a shaped protrusion
for fitting into a matching recess of said driving means in the dispensing apparatus
are also envisaged.
[0085] Furthermore, the inner surface of the medication receiving pockets where medication
rests might be inclined at the same angle to the ground in all the medication receiving
pockets, or said inner surface might be inclined at different angles to the ground
in different medication receiving pockets in the same blister depending on the specific
type of medication contained therein.
[0086] In addition, although the cutting means of the automatic medication dispensing apparatus
have been described as comprising blades configured to move along two different, perpendicular
directions, the blades might be configured to move along different directions inclined
other than perpendicular.
[0087] Locking means might be also included to releasably lock the drive portion of the
blister to the driving means of the automatic medication dispensing apparatus for
preventing the blister from coming out of the automatic medication dispensing apparatus
during use.
[0088] On the other hand, although the body of the blister has been described as being preferably
circular in shape, a blister having other shapes such as a polygonal, oval, etc. is
also envisaged. Examples where the body is not circular but has medication receiving
pockets radially distributed therein are also possible.
[0089] Also, although the blister has been described as being driven in rotation towards
a target dispensing position, the blister might be alternatively displaced along a
linear or curvilinear path towards a target dispensing position.
[0090] Finally, although the blister has been described as being a single-use or non-reusable
element or even a reusable element, there may however be cases where only the body,
or only the foil cover is a single-use or non-reusable element or a reusable element.
[0091] All possible combinations of the described examples are also covered. Thus, the scope
of the present disclosure should not be limited by the example that has been described
herein, but should be determined only by a fair reading of the claims that follow.
