BED FOR SICK AND DISABLED PERSONS

Description

OBJECT OF THE INVENTION

[0001] The present invention, according to the title of this descriptive report, refers to a bed assembly for sick and disabled persons that has been designed to improve the hygiene and the cleaning process of any person that cannot take care of his/herself without said person having to be moved as it is the standard practice, that is, the person in question can remain in the bed that is the object of the present invention.

[0002] The present invention contributes the means and functionality necessary to facilitate the tasks and of the care takers that clean and maintain said disabled persons in a state of hygiene, in a manner that minimizes the inconveniences caused by this care, since all the tasks necessary to accomplish this function can be done without having to move the disabled person from the bed.

BACKGROUND OF THE INVENTION

[0003] Currently, there are several procedures in use to carry out these clearing tasks on disabled and sick persons, unable to move, that entail transporting the disabled person from the bed where he or she habitually lies to the place where his or her personal cleaning and hygienic routines are carried out, procedures that are accompanied by known discomfort and upheaval for the person receiving the care.

[0004] However, due to the weight of the person receiving care and for safety, in most cases this moving is done by means of special cranes, that due to their high cost can only be afforded by large clinics and hospitals, and causing obvious inconveniences and disturbances to the patient, as mentioned before.

[0005] Another problem that arises from providing this type of care, is that in most cases, the care takers of this disabled persons have just enough strength to carry out the hygienic and cleaning tasks, that cause them considerable fatigue and difficulty, and therefore pain and suffering for the disabled person while trying to cater to their needs.

[0006] >

[0007] Document US 1874826 discloses a hospital bed eqquiped with a mechanism for easily and conveniently handling a patient in lying position.

DESCRIPTION OF THE INVENTION

[0008] In order to achieve the objectives and avoid the inconveniences as mentioned above, the present invention proposes a bed assembly for disabled persons characterized in that it comprises a base structure which supports a first bed assembly which incorporates a lower bed assembly that can be pulled out to move in a horizontal plane to extract it together with its bed frame outside of the base structure, while remaining associated to it, and a second upper bed assembly that also incorporates another assembly with its corresponding bed frame and, initially, without a mattress, that sits above the first bed assembly.

[0009] This second upper bed assembly is characterized in that it includes vertical guide means so the upper bed assembly can be placed, in a stable manner, in a horizontal plane at the desired height to be able to clean the patient and/or disabled person and maintain him or her in a hygienic state.

[0010] In this manner, while the disabled person is laying on the mattress of the lower bed on which there are some transversal wide and resistant straps, and said lower bed being inside the base structure, the upper bed assembly will be placed in a low position (if it is not already) until it comes into contact with the lower bed assembly, and while it is in this position, the transversal straps will be hooked by their ends to the bed frame of the upper bed assembly, and with this maneuver the disabled person becomes associated and bound to said upper bed, after which maneuver the bed is elevated until the desired height is reached and the tasks involving washing and cleaning the disabled person, that has obviously been raised together with the upper bed, and is now resting on the transversal straps.

[0011] Another characteristic of the present invention is that it incorporates a bath assembly having a third assembly that moves vertically to collect waste water and excrement produced while washing and cleaning the disabled person. To this effect, this bath assembly will be placed below the upper bed assembly close to it, after having previously pulled the lower bed assembly out from the base structure.

[0012] The assembly object of the present invention is further complemented by an additional independent cart that will be placed underneath the bath assembly to collect waste water and excrement. To this effect said bath assembly is provided with a sloping bottom that empties through its outlet which opens in turns on to the recipient part of said additional cart.

[0013] Once the disabled person has been washed and cleaned, the independent cart is extracted and the bath assembly is placed in plane below that occupied by the lower bed assembly. This operation is followed by placing the upper bed in a lower position until it encounters and contacts the lower bed assembly that is inside the base structure. At this point in the process, the disabled person is again supported by the mattress of the lower bed assembly on which the transversal belts or straps are interposed, that can now be unhooked from the bed frame of the upper bed assembly, that can at this point be made to acquire a lifted position, but without the disabled person that is now laying again on the lower bed assembly.

[0014] We see then, that the caretaker washing and tiding up the disabled person did not have to move the patient directly, that is, the caretaker did not need to exert him or herself physically.

[0015] The base structure is characterized in that it comprises two longitudinal beams that correspond to the sides of the bed assembly object of the invention, a head part and a foot part, each having their respective tubular transversal beams, from each of which two pairs of tubes project vertically, the outer tubes being higher that the inner tubes.

[0016] The outer tubes projecting from the head part of the base structure are associated by means of a low bridge, while the inner columns projecting from the foot part are linked by another low bridge.

[0017] Another characteristic of the present invention is that the means used to raise and lower the upper bed consist in each of the tubes of the head part and the foot part contain inside them a device or mechanism whose function is to raise or lower said upper bed, so that the bed assembly includes an extension portions at its corners that connect to their respective tubes inside pieces that are guided inside the so-called guide tubes, and to this effect the tubes are fitted with vertical grooves that communicate the inside of said columns with the outside.

[0018] Inside each pair of the outer guide tubes associated to the foot part or the head part of the bed assembly, there is an axle spindle to which one of the guide tube inside pieces is threaded, also connected to this inside piece is the end of a chain that is also coupled to the lower sprockets located in the lower part of the guide tubes, and that correspond to the inside of the transversal beams, while the opposite end of said chain is connected to the inside piece of the other guide tube of the same pair, that is also fitted with an upper sprocket in its upper part to which the aforementioned chain is also connected and naturally also goes through the inside of the transversal beams belonging to the head part and the foot part.

[0019] Being the axle spindles rotating, the guide tube inside pieces that are threaded to them will simultaneously drag with them the paired support pieces by means of the chains, raising or lowering the upper bed according to the direction in which said axle spindles are being turned.

[0020] The inner guide tubes also incorporate another mechanism similar to the one described, and which function is to raise and lower the bath assembly through its supporting frame.

[0021] All the axle spindles rotate by means of small motors that transmit their movement by means of pulleys and belts, while being attached to a small arms integral with to the respective upper portions of the respective vertical guide tubes.

[0022] This not withstanding, the motor element could be any such element, for instance a pneumatic or hydraulic cylinder. In that case the axle spindle and motor would be substituted by a cylinder that would be located inside the tubes instead of the axle spindles. In this case, even chains and sprockets could be omitted, in which case cylinders would be incorporated to all the vertical guide tubes and their movements would be synchronized.

[0023] Other characteristics of the present invention refer to the structure formed by the two bed frames and their means to be assembled.

[0024] Each of said bed frames comprises two lateral support pieces centered and integral with the longitudinal beams and two end collapsible frames connected to said centered arms in an articulated manner, said frames corresponding to the body and lower limbs of the disabled or sick user.

[0025] The frame of the lower bed assembly incorporates, at least, one mechanism actuated by a motor which function is to fold and unfold the collapsible frames at different tilt angles according to need, in such a manner that when the bed is inside the base structure below the upper bed, the collapsible action of said frames will be transmitted to the collapsible frames of the upper bed, and in this case, said frames can be connected by means of small plates fitted with articulated means at their ends.

[0026] The bed frame of the upper bed assembly, which is not equipped with a mattress, includes, at the least a central transversal strap secured to both lateral support pieces and, at least, two other transversal straps secured to the lateral sections of the end frames, in such a manner that the straps can be attached or detached at will.

[0027] Another characteristic of the present invention is that the lower bed assembly is associated to the base structure by means of its frame.

[0028] To this effect, the frame incorporates two parallel beams that fit inside corresponding guide tubes integral with the base structure, and offering the possibility of incorporating also lineal ball bearings to achieve a smoother guiding motion. Said guide tubes are naturally located on the side from which the lower bed assembly is pulled out from the main assembly.

[0029] The base structure also includes two wheels coupled to the fixed support pieces and two wheels coupled to the rotating support pieces that are equipped with a break and thus make handling the bed assembly object of the invention an easy task.

[0030] The independent trolley is characterized in that it is determined from a base platform provided with wheels, above which there is a lidded container which function is to collect waste water and excrement, said container is located between the two bridges that arise from the base structure. A handle intended to handle the assembly arises from one of said bridges.

[0031] The container can be raised or lowered to adjust it to the desired height by means of two vertical spindles that rotate through a motor element affixed to one of the two bridges integral with the platform. The container has a tap to empty it of its contents.

[0032] To facilitate the application and use of the trolley, the longitudinal beam of the base structure located on the opposite side of that from which the lower bed assembly is extracted, is susceptible to incorporate a centered bridge, through which the trolley will be inserted without having to raise it from the floor.

[0033] Other characteristic of the present invention is that the different elements of the assembly are assembled in a manner that makes them easily disassembled, this is particularly true of the base structure, in which the manner in which the vertical columns, crosspieces and longitudinal beams are achieved by the characteristic affixing support elements.

[0034] The sick or disabled person is always on the lower bed frame on which the transversal straps are always across, the bath assembly below said bed frame and the upper bed frame placed in the at rest position, which is always in the lower position with the straps unhooked from the corresponding sides, which permits that the articulated lower bed frame and its mattress - patient included- the articulations of the lower bed frame can be actuated without the upper bed frame being inconvenienced in any way, since the upper frame, having the transversal straps loosened on its sides, leave the surface free and empty and the sides of said structure always at a lower plane than that where the patient is resting

[0035] Therefore, when the caretaker needs to raise the occupant the only action required is to hook the loose straps to the sides of the upper bed frame and raise the patient to the desired position. The next step is to move the lower assembly with its bed frame and mattress included laterally to leave the central space of the bed structure free and thus be able to raise the bath assembly to the desired height.

[0036] The transversal straps with the patient in an elevated position can be exchanged without inconveniencing the patient and be able to wash the body parts resting on the initially elevated straps, and once this operation has been concluded other dry straps are set in place of the wet ones in the initial position.

[0037] The next action is to lower the bath assembly to its low position, move the lower rack containing its bed frame, mattress included inside the base structure and immediately after lower the upper bed frame until he patient comes into contact with the mattress surface and the sides are lower than the mattress surface. The straps are unhooked once this position has been reached, but there is no longer need to move the block of the upper bed because it will no longer be an obstacle to any articulation action of the lower bed frame in such a manner that the upper bed frame and is rack will be arranged around the lower bed frame.

[0038] The next section contains a description of the figures intended to facilitate the understanding of the contents of this descriptive report and is an integral part of it. Said description and figures are included for illustrative and not limiting purposes.

DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTIONÓN

[0040] Considering the numbering system adopted in the figures, the bed assembly for sick and disabled persons is determined by a base structure 1 which supports un upper bed assembly 2 without a mattress, which height can be adjusted, a lower bed assembly 3 that can be pulled out towards one of the sides, a bath assembly 4 which height is also adjustable and that is always set below the upper bed assembly 2, a bath assembly intended to collect waste water and excrement once the sick or disabled person has been washed and cleaned while lying on the bed frame 5 of the upper bed assembly 2 and an independent trolley 6 that will be the final recipient of said waste water and excrement.

[0041] The upper bed assembly comprises, to begin with, a rack 7 and the aforementioned bed frame 5, while the lower bed assembly 3, comprises, in addition to rack 8 and bed frame 9, a mattress 10.

[0042] The base structure 1 comprises, to begin with, two tubular longitudinal beams 11 that correspond to the two sides of the bed assembly object of the invention, a head part and a foot part, each with their respective tubular transversal beams 12, from each of which arise two pairs of vertical guide tubes, one pair consisting on outer vertical tubes 13 of greater height that arise from the vicinity of the ends of the transversal beams 12 and the other pair consisting of inner vertical tubes 14 shorter and arising from points that are further from the end of said transversal tubes 12.

[0043] The two outer vertical tubes 13 of the head part are linked by means of a short bridge 15, while the inner vertical tubes 14 of the foot part are linked by means of another shorter bridge 16 similar to the previous bridge.

[0044] The free ends of the other vertical tubes are covered with domed lids 17.

[0045] Joined to the transversal beam 12 of the base structure head part there are two rotating support pieces 18 with wheels 19 that also include a break 20, while joined to the transversal beam 12 belonging to the foot part there are two other fixed support pieces 21 with other wheels 19.

[0046] The transversal beams 12, longitudinal beams 11 and the outer gruide tubes 13 are joined together in a manner that allows them to be disassembled by the characteristic affixing support pieces 22 and screws.

[0047] The inner guide tubes 14 are also joined to the transversal beams 12, in a fashion that allows for disassembly, by other affixing support pieces 23 and other screws.

[0048] Raising and lowering the upper bed assembly 2 to place it in the desired stable horizontal position is achieved by means of a mechanism determined from guiding elements 24 and 25 that are located inside external columns 13, said guiding elements 24 having projecting portions 26 that fit in the corresponding longitudinal grooves 28 of vertical tubes 13, in such a manner that when said projections are coupled by means of pins to other terminal elements 27 integral with the corners of rack 7 of said upper bed assembly 2.

[0049] Raising and lowering the upper bed assembly 2 is then achieved when guiding elements 24 and 25 travel simultaneously. To make this possible, there are coaxial axle spindles 29 inside the two outer guide tubes 13 that are placed opposite to each other in a diagonal arrangement and to which two of the aforementioned support pieces 24 are coupled, each of them connected to the end of chain 30 that runs along the internal part of the transversal beams 12 coupled to two lower sprockets 31 located in said transversal beams 12 aligned to the inside of vertical tubes 13, a third upper sprocket 32 being located in the uppermost part of outer tubes 13 which have no spindles, and said third sprocket that has no the spindles, this third sprocket 32 also coupled to the respective chain 30, which free end finally connects to the respective guiding body 25 found in columns 13 that do not incorporate said axle spindles 29. Said third sprocket 32 is coupled into a piece shaped as an inverted cup 33 crossed by a short axis.

[0050] The coaxial spindles 29 rotate by means of small motors 34 that transmit their movement by means of pulleys 35 and belts 36, while affixed to elongated support pieces 37 perpendicularly integral with the upper portions of the respective vertical vertical tubes 13 to which said spindles 29 are incorporated.

[0051] Therefore when the coaxial spindles 29 are made to rotate, the guiding elements 24 that are threaded to them drag the other two matching 25 through the chains 30, raising or lowering the upper bed assembly 2 depending on which direction they are rotated.

[0052] The inner vertical guide tubes 14 incorporate another mechanism similar to the one described to raise and lower the bath assembly 4 through its supporting rack 38, the reference points of said mechanisms coinciding.

[0053] Bed frames 5 and 9 of the upper bed assembly 2 and lower bed assembly 3 comprise two lateral centered and support pieces 39 and 40 that re joined by means of screws to the longitudinal beams of the respective racks 7 and 8 and two collapsible end frames shaped in a general "U" shape 42 and 43 that are connected in an articulated manner by their free ends to the centered support pieces 39 and 40.

[0054] The bed frame of the lower bed assembly 3 incorporates conventional mechanisms 44 which function is to be able to position, in an independent manner the collapsible frames 43 at various tilt angles according to what is needed at the time and to suit the bed occupant. When this lower bed assembly 3 is below the upper bed assembly 2 and in contact with each other, the movement provided by said mechanism or mechanisms 44 will also be transmitted to the collapsible frames 42 of the upper bed assembly 2. In this case both bed frames 5 and 9 can be associated by means of lateral plates 45 fitted with articulated means at their ends.

[0055] Each of said mechanisms 44 comprises, basically, a fixed transversal body 46 to which a motor 47 is connected, and which shaft is connected to a longitudinal spindle 48 by means of two different threaded sections (one on the left and one o the right) to which the corresponding nut elements 49 and 50 are coupled, and where pairs of parallel plates 51 and 52 are in turn articulated that converge towards a shared transversal shaft 53 where the arms of the respective frames 43 rest in order to collapse upwards or downwards when spindle 48 is made to turn in one way or the other.

[0056] The bed frame 5 of the upper bed assembly 2 includes a wide transversal strap 54 fixed to the two fixed side support pieces 39 and two additional straps 54 fixed to the arms of the two end frames 42. This affixing arrangement can be disassembled and is achieved by screws 55 that fit tightly the end orifices of said transversal straps 54.

[0057] On the other hand, the bed frame of the lower bed assembly 3 includes a set of transversal slats 56 fixed to the lateral support pieces 40 and the frames arms 43.

[0058] The independent trolley 6 comprises a base platform 57 equipped with wheels 58, platform 57 from which two vertical bridges 59 arise and between said bridges there is a container 60 with a removable lid 61 and also having projections 62 at its base that are threaded to a pair of vertical spindles 63 coupled at their ends to parts that are integral with the platform 57 and to the upper part of the bridges 59.

[0059] A motor 64 is affixed to one of the bridges and transmits its rotating motion to one of the spindles 63 to cause the assembly to raise and lower the recipient 60. Both spindles 63 are linked together by means of a shared belt 65 and two end pulleys 66 placed at the lower ends of spindles 63 below platform 57.

[0060] The container 60 incorporates a tap 67 that serves to empty said container after having washed and clean the disabled person.

[0061] Finally, the trolley 6 incorporates a handle 68 to push it and handle it that arises from one of the vertical bridges 59 integral with the base platform 57.

[0062] One of the longitudinal beams of the base structure 1 incorporates a centered bridge 69 through which the trolley 6 can be inserted inside the base structure 1 to place it below the bath assembly 4 to be able to comfortably collect the waste water and excrement while washing and cleaning the disabled person.

[0063] To this effect the bath assembly 4 has a sloping bottom that discharges it contents through discharged outlet 70 which faces the mouth or inlet of the container 60, raising it to the required height until is near discharge 70.

[0064] The lid 61 is a flat piece with a handle that complements frontal groove 72 of the container 60 and a small internal perimetral flange 73 near its mouth to facilitate its movement.

[0065] The lower bed assembly 3 at the base structure 1 comprises a pair of parallel transversal bars 71 integral with its rack 8, bars 71 that adjust to the support pieces guide 41 integral with the base structure 1 in correspondence to the side through which the lower bed assembly 3 is pulled out.

[0066] The arrangement as described, and with the disabled person laying on the mattress 10 of the lower bed assembly 3, on which the wide and resistant transversal straps 54 are, and with said lower bed assembly 3 inside the base structure 1, the upper bed assembly 2 will be placed (provided it has not been placed thus already) in a lower position until it comes into contact with the lower bed assembly 3. At this point in the operation, the transversal straps 54 will be hooked by their end orifices to the screws 55 of the bed frame 5 of upper bed assembly 2, and this operation will associated the disabled person to said upper bed assembly 2, once this has been achieved, the bed assembly 2 will be raised until it reaches the desired height so the disabled person can be washed and cleaned in a comfortable manner.

[0067] Once the washing and cleaning operation has been completed the upper bed assembly 2 will be returned to a lower position until it, again, comes into contact with lower bed assembly 3 set in place inside the base structure 1. At this point the disabled person is returned to a laying position over mattress 10 of the lower bed assembly 3 on which the transversal belts or straps are interposed 54, straps that are then unhooked from the bed frame 5 of the upper bed assembly 2, which can also be placed in a raised position, but without the disabled person, who is now laying again on the lower bed assembly. The transversal straps 54 can also be hooked to other similar lugs 55 solidarious to the bed frame 9 of the lower bed assembly 3 when the disabled person is laying on it.
