FIELD
[0001] Embodiments of the present disclosure generally relate to bands for wearers and more
specifically to improved hospital wristbands for patient safety and/or identification.
INTRODUCTION
[0002] Wristbands can be used in hospital settings for patient safety and/or identification.
These wristbands need to be capable of having information (e.g., identification information)
printed or otherwise provided thereon. Furthermore, these wristbands need to be easily
prepared and donned on a patient, but difficult to remove to ensure the wristbands
to do not inadvertently become detached. Wristbands for some patients (e.g., babies)
may require special care in their construction to ensure the wristband cannot be worn
down by the patient (e.g., chewed through or dissolved by saliva) to ensure that they
do not become a hazard to the patient.
[0003] Wristbands, such as those used in hospitals, can be made using direct thermal materials
which allow the application of information onto the wristband using direct thermal
printing. Direct thermal wristbands (e.g., for hospitals) are manufactured using specialized
equipment such as narrow-width label presses equipped with glue tab applicators. These
wristbands are made from a single type of raw material, often coated polypropylene
or synthetic paper. These wristbands are often shaped using a set of dies mounted
to a narrow width press and at the end of the press a glue tab for fastening is applied
using a glue tab applicator. This process requires significant expertise and specialized
machinery, making it costly and complex.
[0004] Improvement in the field of wristbands is desirable.
SUMMARY
[0005] The present invention relates to direct thermal bands (e.g., wristbands for use in
a hospital and designed to provide patient identification and/or medical information).
The bands described herein can be constructed using laminated materials to enhance
durability and comfort, while simplifying the manufacturing process. The bands described
herein can simplify the manufacturing process by using a laminated raw material composed
of multiple layers, each with specific properties.
[0006] The laminated material can consist of a coated outer layer for high-quality thermal
printing, durability, and chemical resistance, an adhesive middle layer that maintains
adhesion under various conditions, and an inner layer providing comfort and resistance
to skin irritation. Each layer of the raw material can provide a specific set of features
needed to manufacture a direct thermal hospital wristband.
[0007] The laminated material can be converted into a band by die cutting through one of
the layers of the laminated material to access the middle adhesive layer. This approach
can eliminate the need for specialized label presses and glue tab applicators and
obviate the need for a glue tab application step. This can simplify the manufacturing
process and reduce the total cost associated with producing the bands.
[0008] According to an aspect, there is provided a band configured to encircle a portion
of a wearer. The band including an outer layer configured for direct thermal printing,
a middle layer configured to be an adhesive layer, and an inner layer comprising a
peelable portion which, once removed, exposes the middle layer. The inner layer is
laminated to the outer layer with the middle layer there between.
[0009] In some embodiments, the outer layer includes polypropylene.
[0010] In some embodiments, the middle layer includes a marine-grade adhesive.
[0011] In some embodiments, the inner layer includes polyester.
[0012] In some embodiments, the inner layer is laminated onto the outer layer at about 250
°F for about 30 s at about 80 PSI.
[0013] In some embodiments, the outer layer coated with at least one of a chemical layer
receptive to thermal printing and a UV coating.
[0014] In some embodiments, the band further includes a narrow border along the edge of
the band including the inner layer.
[0015] In some embodiments, the band is die cut into shape and the inner layer is die cut
with an incision to provide a peelable portion.
[0016] In some embodiments, the band is configured to encircle at least one of a wrist,
an arm, an ankle, and a leg of the wearer.
[0017] In some embodiments, the band is a hospital wristband.
[0018] According to an aspect, there is provided a method of manufacturing a band configured
to encircle a portion of a wearer. The method includes coating an outer layer with
an adhesive, laminating an inner layer to the outer layer to form a three-layered
laminated material, wherein the adhesive makes up a middle layer, die cutting the
three-layered laminated material into a band.
[0019] In some embodiments, the outer layer includes polypropylene.
[0020] In some embodiments, the middle layer includes a marine-grade adhesive.
[0021] In some embodiments, the inner layer includes polyester.
[0022] In some embodiments, laminating the inner layer includes laminating the inner layer
onto the outer layer at about 250 °F for about 30 s at about 80 PSI.
[0023] In some embodiments, the method further includes at least one of applying a chemical
layer receptive to thermal printing to the outer layer and UV coating the outer layer.
[0024] In some embodiments, die cutting leaves a narrow border of the inner layer along
the edge of the band.
[0025] In some embodiments, die cutting the three-layered laminated material includes incising
the inner layer to provide a peelable portion.
[0026] In some embodiments, the band is configured to encircle at least one of a wrist,
an arm, an ankle, and a leg of the wearer.
[0027] In some embodiments, the band is a hospital wristband.

THE LAMINATED MATERIAL
[0036] FIG. 1A shows a cross-sectional side view of a three-layered laminated material 100, according
to some embodiments.
[0037] The bands described herein can be constructed from a three-layer laminated material
100. The three-layered laminated material 100 can be fabricated from an outer layer
102, a middle layer 104, and an inner layer 106. Each layer may provide functionality
for the final product.
[0038] The outer layer 102 can be made of a material suitable for direct thermal printing.
The outer layer 102 may be a material that is specially treated to be suitable for
direct thermal printing. Information printed (e.g., direct thermally printed) on the
outer layer 102 can remain legible and intact for the duration of the product's use
(e.g., the lifetime of the wristband). The outer layer 102 can be durable, flexible,
and resistant to chemical (e.g., cleaning and disinfecting liquids) and/or physical
abuse. In some embodiments, the outer layer 102 can be fabricated from polypropylene.
In some embodiments, derivatives and/or analogues of polypropylene can be used to
make the outer layer 102. In some embodiments, the outer layer 102 can be between
1 mm and 5 mm in thickness.
[0039] The middle layer 104 can be an adhesive layer configured to maintain adhesion properties
during use. Preferentially, the middle layer 104 can maintain its adhesion properties
for, for example, up to fifteen days. Preferentially, the middle layer 104 can maintain
adhesion even during/after exposure to bodily fluids, water (cold, hot, or lukewarm),
alcohol, cleaning and disinfecting liquids, and/or body heat. The middle layer 104
can ensure that the final product (the band) remains securely fastened without requiring
additional equipment or adhesives during application. In some embodiments, the middle
layer 104 comprises a marine-grade adhesive. In some embodiments, the middle layer
104 can comprise a urethane polymer that includes distilled water, docusate sodium,
and ethanol blended together.
[0040] The inner layer 106 is configured to be gentle for the skin of a wearer while maintaining
its structural integrity. The inner layer 106 can provide a comfortable interface
with a wearer's skin that can prevent irritation and maintain durability against chemical
(e.g., cleaning and disinfecting liquids) and/or physical abuse. In some embodiments,
the inner layer 106 comprises polyester. In some embodiments, the polyester comprises
a food-grade polyester. In some embodiments, the inner layer 106 can have a thickness
between 0.5 and 5 mm.
[0042] In some embodiments, the three-layered laminated material 100 can enable high-quality
thermal printing thereon (so that printed information is legible and long lasting).
In some embodiments, the three-layered laminated material 100 can provide flexibility
that can ensure that any resulting wristbands can be used on wrists of various sizes.
In some embodiments, wristbands made from the three-layered laminated material 100
can provide durable adhesion for secure fastening, resistance to chemicals (e.g.,
cleaning and disinfecting liquids), bodily fluids, and/or physical stress for up to,
for example, fifteen days, and comfort with prolonged skin contact.
[0043] In some embodiments, the materials making up the three-layer laminated material 100
(and consequently the final band) can be selected to provide bacterial resistance.
For example, using polypropylene in the outer layer 102, marine-grade adhesive in
as the adhesive middle layer 104, and food-grade polyester as the inner layer 106
may provide bacterial resistance.
[0044] FIG. 1B shows a cross-sectional perspective view of a three-layered laminated material 100
with a chemical layer 103 and a UV-coating 109, according to some embodiments.
[0045] As described above, the outer layer 102 may be a material that is specially treated
to be suitable for direct thermal printing. For example, the outer layer 102 may be
treated with a chemical layer 103 such as bisphenol-A (
BPA) or bisphenol-S (
BPS) (shown as layer 103 on the outer layer 102) to make the outer layer 102 receptive
to thermal printing.
[0046] In some embodiments, a UV-coating 109 is applied to the outer layer 102 (e.g., on
the chemical layer 103 if one is provided). The UV-coating 109 can prevent any print
that is thermally printed thereon from smudging or degrading for a number of days.
The UV-coating 109 may also prevent any chemicals in the outer layer 102 or the chemical
layer 103 (e.g., a chemical layer such as BPA or BPS) from being exposed to the wearer.
MANUFACTURING PROCESS
[0047] FIG. 2 shows a process diagram of a method 200 of manufacturing bands, according to embodiments
described herein.
[0048] The method 200 includes the steps of laminating the outer layer 102 (which is coated
with the middle layer 104) to the inner layer 106 to form the three-layered laminated
material 100 (block 202), die cutting the three-layered laminated material 100 into
shape (block 204), and removing matrix (block 206).
[0049] FIG. 6A shows the printing process of the laminated material 100, according to some embodiments.
This step may occur before the lamination (block 202). This step may apply, for example,
guides (e.g., guides to show where a peelable region is) or logos.
[0050] During lamination (block 202), the outer layer 102 (e.g., polypropylene) can be coated
with the middle layer 104 (e.g., a marine-grade adhesive). The outer layer 102 is
then laminated to the inner layer 106 (e.g., polyester). The lamination may, for example,
take place at a temperature of about 250 °F for about 30 seconds under a pressure
of about 80 PSI or other suitable conditions. This lamination process can create a
strong bond between the layers, forming a durable and flexible three-layered material
100 suitable for, for example, bands. This lamination process can ensure that when
someone attempts to remove the band, the band tears/separates to show that it's been
tampered with (tamper evidence). The lamination process can also help the final band
withstand high temperature variations and moisture, such as a shower, pool, whirlpool
environments.
[0051] Because the method 200 does not apply an adhesive tab in a separate step, a better
grade of adhesive (e.g., marine-grade glue) can be implemented in the bands. Specifically,
because the lamination process (block 202) can take place at only about 250 °F, a
marine-grade adhesive can be used. This adhesive (e.g., the marine-grade glue) may
be superior to those implemented in "hotmelt" applications that apply the adhesive
tab.
[0052] Using better adhesive can aide the bands in staying affixed to the wearer for longer
durations. This may reduce the frequency with which the bands need to be replaced.
This may also avoid situations wherein the band comes off of a wearer and creates
a dangerous situation. For example, bands with adhesives that can better withstand
dissolution by saliva may not come off of an infant wearer's wrist as easily. This
may ensure that the bands do not become choking hazards for infant wearers.
[0053] In some embodiments, the outer layer 102 can be coated with a chemical layer 103
and/or a UV-coating 109. The chemical layer 103 may be BPA or BPS to make the outer
layer 102 receptive to thermal printing. Other chemical layers 103 are contemplated.
The UV-coating 109 can be used to enhance the durability of the printed information
and provide additional resistance to environmental factors. In some embodiments, the
UV-coating 109 may be between 100-300 mm in thickness.
[0054] FIG. 6B shows the die cut process of the laminated material 100 (block 204), according to
some embodiments.
[0055] During die cutting (block 204), the three-layered laminated material 100 can be die
cut into the shape of the final products (e.g., wristbands).
FIG. 3A shows a plan view of the outer layer 102 of a sheet of laminated material 100 that
has been cut into bands, according to some embodiments.
FIG. 3B shows a plan view of the inner layer 106 of a sheet of laminated material 100 that
has been cut into bands, according to some embodiments. In some embodiments, the die
cut can cut the outer layer 102 (e.g., the polypropylene layer). When the outer layer
102 is removed, the adhesive middle layer 104 may also come off with the outer layer
102 leaving only the inner layer 106 (e.g., the polyester layer). The outer layer
102 may be cut away from the exterior of the band leaving a thin border 107 of the
inner layer 106. In some embodiments, this narrow border is 0.5-2 mm wide. This thin
border 107 may prevent the adhesive middle layer 104 from leaking into a thermal printer
during the thermal printing process. This may reduce the frequency of printer breakdowns
or reduce the amount of maintenance the printers require.
[0056] The die cut can also cut an incision 110 in inner layer 106 to provide a peelable
portion 108 of the inner layer 106. The incision 110 may be a full incision, a scoring,
or other method suitable to make a portion of the inner layer 106 more readily removable.
In use, the peelable portion 108 can be peeled from the laminated material 100 exposing
the adhesive middle layer 104 which can be adhered to the outer layer 102 at the other
side of the band when encircling the wearer's, for example, wrist. The outer layer
102 can further be cut around a peelable portion 108 of the inner layer 106 to provide
an easy mechanism for the user to pull at (see the circular cut 114 proximate to the
incision 110). The die-cutting process can use precision tools to ensure that each
wristband is identical and meets the required specifications.
[0057] FIG. 6C shows the removal of the matrix from the laminated material 100 (block 206), according
to some embodiments.
[0058] During matrix removal (block 206), the excess material (i.e., the cut away outer
layer 102 and adhesive middle layer 104) is removed from the die-cut band, leaving
only the band. In some embodiments, the three-layered laminated material 100 is cut
into several rows of bands (e.g., wristbands) at once (see, e.g., the rolled rows
of bands 400 in
FIG. 4A). In such embodiments, the rows can be slit into individual tapes of bands (e.g.,
wristbands). The die-cut three-layered material 100 can be run through a standard
label press process in which the matrix can be removed and die-cut three-layered material
100 slit into individual width rolls of bands. In some embodiments, the tape of bands
can be rewound into rolls of the bands (e.g., into rolls of wristbands). The rewinding
process can divide the tape of bands into rolls of the appropriate quantity (see,
e.g., the single roll of bands 402 in
FIG. 4B) on, for example, rewinding equipment. This can ensure that the bands are easy to
handle and apply in a hospital setting.
[0059] According to an aspect, there is provided a method 200 of manufacturing a band 500
configured to encircle a portion of a wearer. The method 200 includes coating an outer
layer 102 with an adhesive, laminating an inner layer 106 to the outer layer to form
a three-layered laminated material 100 (block 202), wherein the adhesive makes up
a middle layer 104, die cutting the three-layered laminated material 100 into a band
500 (block 204).
[0060] In some embodiments, the outer layer 102 includes polypropylene.
[0061] In some embodiments, the middle layer 104 includes a marine-grade adhesive.
[0062] In some embodiments, the inner layer 106 includes polyester.
[0063] In some embodiments, laminating the inner layer 106 (block 202) includes laminating
the inner layer 106 onto the outer layer 102 at about 250 °F for about 30 s at about
80 PSI.
[0064] In some embodiments, the method 200 further includes at least one of applying a chemical
layer 103 receptive to thermal printing to the outer layer 102 and UV coating 109
the outer layer 102.
[0065] In some embodiments, die cutting (block 204) leaves a narrow border 107 of the inner
layer 106 along the edge of the band 500.
[0066] In some embodiments, die cutting the three-layered laminated material 100 includes
incising the inner layer 106 to provide a peelable portion 108.
[0067] In some embodiments, the band 500 is configured to encircle at least one of a wrist,
an arm, an ankle, and a leg of the wearer.
[0068] In some embodiments, the band 500 is a hospital wristband.

[0070] FIG. 5B shows a plan view of the inner layer 106 of a band 500 (e.g., a wristband), according
to some embodiments.
[0071] Once removed from the roll, the band 500 can have information printed thereon using,
for example, a direct thermal printer. To apply the band 500 to the wearer, an adhesive
portion of the band 500 can be exposed by peeling off the peelable region 108 of the
inner layer 106 (e.g., by pulling at the circular cut 114). The band 500 can encircle
a portion of the wearer (e.g., their wrist) and the exposed adhesive portion can be
affixed to the opposite end 112 of the outer layer 102 to form a closed loop. The
outer layer 102 facing outward from the wearer and the inner layer 106 facing towards
the wearer.
[0072] According to an aspect, there is provided a band 500 configured to encircle a portion
of a wearer. The band 500 including an outer layer 102 configured for direct thermal
printing, a middle layer 104 configured to be an adhesive layer, and an inner layer
106 comprising a peelable portion 108 which, once removed, exposes the middle layer
104. The inner layer 106 is laminated to the outer layer 102 with the middle layer
104 there between.
[0073] In some embodiments, the outer layer 102 includes polypropylene.
[0074] In some embodiments, the middle layer 104 includes a marine-grade adhesive.
[0075] In some embodiments, the inner layer 106 includes polyester.
[0076] In some embodiments, the inner layer 106 is laminated onto the outer layer 102 at
about 250 °F for about 30 s at about 80 PSI.

[0079] In some embodiments, the band 500 is die cut into shape and the inner layer 106 is
die cut with an incision 110 to provide a peelable portion 108.
[0080] In some embodiments, the band 500 is configured to encircle at least one of a wrist,
an arm, an ankle, and a leg of the wearer.
[0081] In some embodiments, the band 500 is a hospital wristband.
[0082] Producing a band (e.g., a direct thermal printed wristband for use in a hospital
to identify and/or provide information on patients) as described herein may provide
a simplified manufacturing process that can reduce the need for specialized equipment
and skilled operators. This can reduce the overall cost of manufacturing the bands.
Producing bands based on the methods described herein may also provide bands of enhanced
durability which may remain functional and comfortable for up to, for example, fifteen
days. The bands described herein may provide a substrate for high-quality thermal
printing that may maintain legibility and information integrity. The manufacturing
processes described herein may be cost-effective which may make the bands more accessible
to hospitals and/or healthcare providers.
[0083] While the foregoing discussion has focussed on direct thermal printing wristbands
for use in a hospital setting, other implementations are possible without deviating
from the teachings described herein. For example, the band may be configured to encircle
or otherwise secure to another portion of a wearer's body. For example, an armband,
leg band, or ankle band are also capable of manufacture and use as described herein.
Furthermore, the bands may find use in settings outside the hospital. For example,
these may be useful in long-term care facilities or other institutional settings.
The bands may find use in any variety of wristband intended for long-term wear (e.g.,
multiple days) by the wearer and/or where the band must withstand chemical (e.g.,
cleaning and disinfecting liquids) and/or physical abuse. For example, the bands may
find use in disaster relief settings to identify victims or other settings wherein
identification of individuals may be beneficial.
