BACKGROUND OF THE INVENTION
[0002] Embodiments of the invention relate to the field of medical
devices and more particularly to solid elastomers applied to an
area of discomfort for purposes of heating or cooling the area,
providing compression to the area, aerating the area, and/or
providing padding to the area. No existing device provides such a
combination of affects to provide optimal functionality and use for
the wearer.
[0003] It is commonplace for people to utilize devices with thermal
capacitance to treat an injury or area of discomfort. A hot-cold
pack is an example of one such widely utilized device. Cold packs
are generally used in order to numb an area and relieve swelling,
while hot packs are used to loosen up tight muscles or tendon
strains. Many hot-cold packs utilize a gelatinous substance that
can undergo state changes in order to provide a higher capacity of
heat absorption, i.e., cooling. Such gels may provide similar
functionality using water or chemical compounds that initiate
changes in state (i.e., liquid to solid). A majority of hot-cold
packs and other similar devices store the gel or liquid based
substance that provides thermal capacitance in a sealed bag. A
problem with this approach is that over time, these bags often leak
or otherwise degrade to a point where use is impractical
[0004] Another issue with using current hot-cold packs is that
problems can arise when the treatment area receives little air, as
the underlying area can become sweaty and the hot-cold pack can
laterally or vertically slide around on the treatment area during
movement of the recipient. Thus, in some instances application of
the hot-cold pack can further aggravate the injury, or frustrate
the wearer to the point of not using the hot-cold pack.
[0005] Existing hot-cold packs are designed for use on immobile
subjects and generally lack an effective securing mechanism. When
the subject of the hot-cold pack treatment is an athlete, animal or
a young child or any other entity requiring continued mobility, it
is important to adequately secure the pack to the subject. Securing
the hot-cold packs is typically achieved by a secondary means.
Generally, the packs are held in place with an elastic bandage
which limits the mobility of movement of recipient of the pack
since the pack may easily become displaced and fall off. In other
instances, the packs are held in place within a pouch that acts as
a means for immobilizing and securing the pouch to a subject,
however the packs are still heavy and even if secured tightly still
inhibit mobility due to their weight and thickness.
[0006] In certain instances it is desirable to compress the
hot-cold pack against the region of treatment. Current hot-cold
packs lack the elasticity required to perform such compression. It
is, however, possible to use a secondary means, namely by an
elastic bandage wound around the hot-cold pack, to compress the
hot-cold pack against the region to be treated. Thus, some
compression type inventions require a secondary device in order to
use the hot-cold pack. This is inconvenient in that a person
wishing to apply the hot-cold pack to an area for treatment is
required to utilize two items before application of the hot-cold
pack can occur. In addition, the elastic properties of straps are
known to degrade over time, resulting in a poor compression as the
age of the strap increases.
[0007] The bandage described in U.S. Pat. No. 5,160,328, filed Nov.
3, 1992 to Cartmell, et al., entitled "Hydrogel bandage" consists
of a self-adhesive bandage including a substrate having a two sides
and multiple layers including a backing layer which forms the first
side of the substrate, and an adhesive layer which forms the second
side of the substrate. A hydrogel layer is disposed over the second
side of the substrate and is made from a polyurethane hydrogel
material for absorbing bodily fluids, including wound exudate.
Multiple support layers may be interposed between the substrate and
the hydrogel layer to provide the bandage with additional support.
Although lightweight, and providing a means for aerating a wound,
the bandage is incapable of providing compressive means to bear on
the wound since the adhesive layer locks the bandage in place over
a treatment area.
[0008] The bandage described in U.S. Pat. No. 5,531,670, filed Jul.
2, 1996 to Westby, et al., entitled "Heat Conserving Bandage"
consists of a heat conserving bandage to cover human or animal
tissue, comprising heat reflecting means, positioned next to the
tissue for reflecting heat from the tissue, insulation material
means covering said heat reflecting means, and cloth covering the
insulation material. The heat reflecting means includes a
sandwiched structure of a foil of plastic material adjacent to the
tissue, and a second foil bonded thereto. Further cloth means can
be inserted between the heat reflecting means the tissue. Suitably,
the cloth means and the heat reflecting means are bonded together
by sewing or an adhesive to create a pocket for receiving the
insulation material. Although lightweight and flexible, the
invention described provides no means for aerating the treatment
area, and indeed attempts not to aerate a treatment area since it
is providing a means to insulate only, and not add or remove
heat.
[0009] The compress described in U.S. Pat. No. 4,556,055, filed
Dec. 3, 1985 to Bonner, entitled "Cold Compress", consists of a
bandage defined by a layer of closed cell foam polymeric material
sandwiched between and bonded to adjacent layers of fabric. One of
the layers of fabric is absorbent with respect to aqueous liquids,
such as wound exudate, and is adapted to be in contact with an area
of the body. Multiple straps are releasably attached to the bandage
to form a compress. The straps facilitate adjustment of the
compress, the compress also may possess elongated pockets may be
sewn to the fabric layer opposite the absorbent layer for insertion
of straps to form a brace or provide for additional cooling.
Electrodes are contemplated for providing electrical stimulation.
Although allowing for application of a cold pad on a treatment area
with a compress, the invention is heavy, thus compromising
mobility, and is cloth wrapped in order to absorb aqueous fluids.
The bandage also allows for electrical stimulation.
[0010] The pad described in U.S. Pat. No. 4,588,400, filed May 13,
1986 to Ring, et al., entitled "Liquid loaded pad for medical
applications", consists of wound and burn dressings which are
prepared from pellicles, which are a thin film of
microbially-produced cellulose obtained, for example, by culturing
Acetobacter xylinum. A pellicle having a thickness from about 0.1
to 15 millimeters or greater is processed to replace the culture
medium with water or other physiologically compatible liquid. The
liquid-loaded pellicle is sterilized prior to its use as a dressing
or in other medical applications. The pad is liquid based, is
heavy, and therefore does not allow for complete mobility or direct
aeration. It also appears to be directed towards immobile burn
victims, hence it is not designed to provide a compressive
means.
[0011] The therapeutic cooling device described in U.S. Patent
Application 20020103520, filed Aug. 1, 2002 to Latham, entitled
"Therapeutic cooling devices", consists of a thermal regulatory
system to reduce swelling caused by trauma to a variety of tissues
and limbs. One or more substantially flexible, at least partially
thermally conductive housings containing an activatable thermal
regulatory medium may be coupled with one or more applicator, such
as a splint, that is adapted to apply the thermal source to the
tissue. The invention also discloses methods of therapeutically
regulating tissue temperature. The invention relates to thermal
regulatory systems that are generally heavy gel filled devices that
are form fitted for a particular body part not allowing mobility,
and providing no means for compressing a treatment area.
[0012] The therapeutic pack described in U.S. Pat. No. 5,190,033,
filed May 2, 1993 to Johnson, entitled "Ice peas cold/hot
therapeutic pack", consists of an improved cold/hot pack for
physiotherapy having a completely sealed flexible pouch. The cavity
of the pouch is filled with a plurality of approximately pea sized
or larger hollow capsules. The cavities of the hollow capsules are
filled with cold/hot storing fluid or gel and are essentially used
as a replacement for frozen peas. Partitions prevent migration of
the capsules within the pouch and a screened plug permits air to be
expelled from the pouch while the capsules are retained in order to
conform the pouch to a given body part. The invention appears to be
flexible but contains capsules in a pouch that would inhibit
mobility when the pouch was strapped on. In addition, the invention
would not allow the underlying treatment area to be aerated. The
invention appears have no means for applying a compressive force
and is directed mainly to cooling of the treatment area solely in a
manner mirroring the use of frozen vegetable bags.
[0013] The therapeutic device described in U.S. Pat. No. 4,592,358,
filed Jun. 3, 1986 to Westplate, entitled "Therapeutic device",
consists of a therapeutic device featuring a plurality of
compartments enclosing a therapeutic substance such as a
refrigerant material which remains a liquid or forms a slush at
temperatures below about 0 degree Celsius, or a heat releasing
substance, or a high density material which may be firmly
positioned on various body portions using one or more strap means.
The invention does not allow for aeration of an underlying
treatment area, and uses liquid in order to cool, or a high density
material to heat. Each mode of use would not allow for mobility or
compression since the device provides non-elastic straps for
fastening the device. The device can not be cut for formed into a
shape other than that supplied.
[0014] The compress described in U.S. Pat. No. 5,697,961, filed
Dec. 16, 1997 to Kiamil, entitled "Compress for use in cold and/or
hot treatment of an injury", consists of a compress suitable for
use in hot and cold treatments of an animal or human body part,
comprising a flexible container containing a formulation comprising
an aqueous solution and discrete particles of a crosslinked,
water-absorbing polymer. In one embodiment, the compress is
contained in a sealed plastic bag. The formulation used in the
compress can be an anti-freeze agent, a salt compound, a glycol
compound or mixtures thereof. The crosslinked, water-absorbing
polymer in one embodiment is polyacrylamide or sodium polyacrylate.
The invention applies a compressive force to a treatment area, but
does not allow for aeration, is heavy, can require an external heat
storage unit attached to the compress and is therefore unable to
provide mobility. In addition the device cannot be cut to fit a
treatment area.
[0015] The bandage described in U.S. Pat. No. 5,431,622, filed Jul.
11, 1995 to Pyrozyk et al., entitled "Thermal bandage", consists of
a thermal bandage apparatus for simultaneously dressing and
thermally treating a wounded area. The device includes a fluid
absorbent member having a wound contacting surface for absorbing
bodily fluids produced by an open wound and a holding means
adjacent and connected to the fluid absorbent member for holding a
thermal medium against the fluid absorbent member such that heat is
transferred between the thermal medium and the open wound by
thermal conduction through the fluid absorbent member. There is
also disclosure of an arrangement for providing a continuous supply
of heat or cold to a wound. The invention is a non-aerating, and
fluid absorbing bandage with associated thermal source pump
attached or pouches for the insertion of gel bags. The invention,
therefore, does not allow for mobilility, aeration or
compression.
[0016] The bandage described in U.S. Pat. No. 5,887,437, filed Mar.
30, 1999 to Maxim, entitled "Self-adhering cold pack", consists of
a self-adhering cold pack having an envelope defining a sealed cold
pack volume. A cooling agent is positioned in the cold pack volume.
A bandage sheet is fixed to the envelope by a bandage adhesive. The
bandage sheet defines mounting tabs linearly extending from the
envelope outer perimeter in order to support a bandage adhesive for
temporary adhesion of the cold pack to the skin surface of a
patient. The invention does not allow for aeration, is heavy and
would not allow for compression of the treatment area.
[0017] The bandage described in U.S. Pat. No. 6,528,696 filed Mar.
4, 2003, to Ireland, entitled "Pliable contact bandage", consists
of a pliable contact bandage for placement over a wound site
located on any skin surface. The apparatus includes a re-openable,
flexible enclosure adapted to receive a source of heat or cold, and
an adhesive for mounting the pliable contact bandage on a skin
surface. The source of heat or cold is temporarily placed within
the flexible enclosure and the pliable contact bandage is placed
over the wound site in a heat conducting relationship. Typically, a
hypo-allergenic adhesive is located along at least a portion of the
periphery of the flexible enclosure. The periphery of the flexible
enclosure surrounds the wound site. There is no attempt made at
enabling mobility or aeration, or compression of the treatment
area.
[0018] The elastomer described in U.S. Pat. No. 5,334,646, filed
Aug. 8, 1994, to Chen, entitled "Thermoplastic elastomer gelatinous
articles", consists of novel gelatinous compositions and articles
formed from an intimate melt blend admixture of
poly(styrene-ethylene-butylene-styrene) triblock copolymer and high
levels of a plasticizing oil. The gelatinous composition is
transparent and has properties including unexpectedly high
elongation and tensile strength and excellent shape retention after
extreme deformation under high-velocity impact and stress
conditions. The gelatinous products of this invention are soft,
flexible, and have elastic memory, characterized by a gel rigidity
of from about 20 gram to about 700 gram Bloom. The invention is an
elastomer and articles of manufacture based on the gelatinous
elastomer. The patent however does not enable the creation of an
aerating, mobile embodiment, or enable the manufacture of an
embodiment with additives allowing for higher heat capacity.
[0019] The elastomer described in U.S. Pat. No. 5,994,450, filed
Nov. 30, 1999, to Pearce, entitled "Gelatinous elastomer and
methods of making and using the same and articles made therefrom"
consists of gelatinous elastomers, methods for making gelatinous
elastomers, methods for using gelatinous elastomers, products made
from gelatinous elastomers, and products which include gelatinous
elastomers as a component or ingredient. More particularly, the
invention includes a gelatinous elastomer formed from a combination
of a block copolymer of the general configuration A-B-A and a
plasticizer. The preferred A-B-A copolymer of the invention is
polystyrene-hydrogenated poly(isoprene+butadiene)-polystyrene and
the preferred plasticizer is either mineral oil or a combination of
mineral oil and resin. Various other components may be included in
the preferred recipes according to the invention. This invention
includes improvements to Chen's '646 invention, but does not enable
the construction of a lightweight, aerating, mobile, compressive
bandage.
[0020] Because of the problems associated with current systems,
there is a need for an improved bandage that adequately overcomes
the limitations existent in the prior art.
BRIEF SUMMARY OF THE INVENTION
[0021] Embodiments of the invention are directed to a support
device that comprises a flexible thermal capacitive elastomer
configured for use as a bandage and/or to provide compression,
padding and/or insulation. The elastomer is designed to retain
alterations in temperature so that when applied to an area in need
of treatment it changes the temperature of that area while
simultaneously aerating and allowing for padding and compression to
be applied to the area under treatment. Such abilities are achieved
in accordance with one or more embodiments of the invention by
molding the material into a planar or other form that comprises a
set of interspersed perforations that increase the devices'
elasticity and "grip", (i.e., the traction of the bandage against
the treatment area), while allowing for aeration of the treatment
area. The device is however not limited to a particular shape and
is intended for use in any dimension that has a suitable purpose.
In some instances it is beneficial to vary the total surface area
of the material so that the material effectively covers the
treatment area.
[0022] To provide compression to specific parts of the body various
shapes that conform to various appendages are contemplated. An
adaptation for example that is formed in the shape of an open ended
tube having a circumference that differs based on the appendage for
which the compressive bandage is to be used is within the scope and
spirit of the invention. The area targeted for application
generally dictates the shape and circumference of the compressive
bandage. In one embodiment of the invention users of the device can
adjust the size by cutting the elastomer material into any desired
shape. Since the material that makes up the device is solid there
are no leakage problems of the sort that exist with existing
medical cold or hot press type devices. It is possible to increase
or decrease the material's heat capacitance by adjusting the
thickness to suit the intended use. Also, the thicker and wider the
material, the more force required to change the shape. Since the
device makes use of a flexible material, the problems existent in
the prior art, namely rupturing and other forms of degradation, are
overcome.
[0023] To provide more or less air flow to the area subject to
treatment, the material may contain a set of interspersed
perforations that vary in size and quantity. The perforations may
take any shape or arrangement that allows air to flow to the
treatment area. The perforations may, for instance, be geometric or
customized to take advantage of a particular niche market. In
instances where the target market is identifiable, the perforations
may take a form suitable for that market. If, for example, the
bandage was intended for use in a children's hospital the
perforations (and/or shape of the bandage itself) may take the form
of a popular cartoon or other such character. Company logos or
interesting patterns might also be used to provide further interest
to the material itself.
[0024] One or more embodiments of the invention enable improved
mobility while the device is in use. The material may, for
instance, contain an adhesive end, VELCRO.RTM. attach areas or male
extrusions that fit or snap into the perforations in order to
secure the bandage to the treatment area while maintaining a
compressive force and still allowing aeration of the area being
treated. The material also provides insulation and padding in
instances where it might be desired. In the tube embodiment
fastening mechanisms are not required but may be optionally
provided to increase the compressive force if desired. Readers
should note, however, that the invention is not limited to these
specific attachment means and contemplates the use of any mechanism
able to limit movement of the bandage when applied to the treatment
area.
[0025] Various applications of the support device are contemplated
and thus the device may be used in contexts where it is beneficial
for the wearer to have an appendage in contact with the elastomer
material. A sock, for example, that is formed of the elastomer
material and worn to provide compressive treatment, comfort or
insulation is one possible implementation. The size and shape of
the sock is modified to fit the appendage it is intended for use
with. One size for instance might be shaped and sized for use on
feet and thus have application in conjunction with footwear such as
shoes or ski boots. When used in this context the elastomer
material provides the user with insulation and padding beyond that
provided by the shoe itself. The same general concept, that being
that the material applied around and appendage can provide
insulation and padding is applicable to others sorts of apparel or
medical devices as well. The material may, for instance be woven
into or made part of bandages, splints, or even basic clothing
apparel where additional padding is beneficial such as in the
context of sports or for those who have an injury that is made more
comfortable through the use of additional padding or compression to
the area of injury.

DETAILED DESCRIPTION
[0034] A tubular compressive device and methods of use relating to
same will now be described. In the following exemplary description
numerous specific details are set forth in order to provide a more
thorough understanding of embodiments of the invention. It will be
apparent, however, to an artisan of ordinary skill that the present
invention may be practiced without incorporating all aspects of the
specific details described herein. In other instances, specific
features, quantities, or measurements well known to those of
ordinary skill in the art have not been described in detail so as
not to obscure the invention. Readers should note that although
examples of the invention are set forth herein, the claims, and the
full scope of any equivalents, are what define the metes and bounds
of the invention.
[0035] Embodiments of the invention are directed to a crosslinked
high-polymer materials with elastic behavior (e.g., an elastomer)
formed for use as a compression wrap. The material that makes up
the wrap is designed to retain alterations in temperature so that
when applied to an area in need of treatment the wrap effectuates a
change in temperature to that area while simultaneously aerating
and allowing for compression to be applied. Thus, the material used
to implement one or more aspects of the invention provides a
mechanism for cooling or heating an area of a person or animal that
has been injured or is in discomfort. In addition to affecting
changes in temperature to an area the device is also adaptable for
use for purposes of providing compression to a person or animals
appendage and/or insulation or padding in cases where that is
desired to increase comfort.
[0036] In the case where a user wishes to cold treat an area, the
user can cool the device by exposing the elastomer material to a
refrigerated environment for a duration of time adequate enough to
bring the material's temperature to a level sufficient for the
intended use. Once the material is at an appropriate temperature,
the user may apply it to the desired area for purposes of cooling
that area. Conversely, by placing the material in warm or hot
water, the user may apply the bandage to the desired area for
purposes of warming that area. One major advantage of using a gel
like material such as an elastomer for the device is that the
temperature of the gel is manageable and does not get uncomfortably
cold for the wearer. This avoids the problem ice packs and other
chemical based cold materials have in that they get so cold they
cannot be put in contact with the skin without causing discomfort
or freezer burn. Because of the elastic properties of the material,
users can optionally utilize the device to tightly wrap the area
being treated and thereby simultaneously apply compression and cold
or hot treatment to that area. The solid material retains its
elasticity in hot or cold applications and can provide compression
in either situation. The material can also be used as a source for
applying aerated compression, padding and/or insulation without the
need to effectuate changes in the material's surface temperature.
In one embodiment of the invention the material is treated with a
chemical that permits the color of the material to alter based on a
temperature suited for a specific treatment. When the material is
adequately cooled for instance, it may have an appropriate color of
blue and when the material is heated it may turn yellow. If heated
to a temperature that may cause burns or is inappropriate for the
desired treatment the material may become red or any other suitable
color. The concept of correlating a color to a specific temperature
range and then varying the color based on the temperature is not
color specific and hence any color may be used in conjunction with
a specific range.
[0037] FIG. 1 depicts an example configured in accordance with an
embodiment of the invention for use as a compressive wrap. In the
example illustrated, the flexible material is molded into a planar
form 100 that comprises a set of interspersed perforations 101,
102, 103 designed to increase or maintain elasticity while allowing
for aeration of the area subject to treatment and compression. In
one embodiment of the invention the planar form is achieved via an
injection mold process that utilizes an elastomer material (e.g., a
polyurethane with the addition of silicon and vegetable oil) having
properties of thermal capacitance and adequate elasticity. It is
important, however, that readers be cognizant of the fact that it
is feasible to implement embodiments of the invention using many
different types of elastomers or other compounds and that as such
embodiments of the invention include, but are not limited solely to
polyurethane elastomers.
[0038] It is advantageous to utilize the planar form because such a
shape maximizes the surface area able to contact the treatment
area. However, the invention also contemplates the use of other
dimensions and can take any shape, thickness, and size suitable to
meet a particular need. For instance, by using a cutting implement
(e.g., scissors, a box cutter, knife, etc. . . . ) users may cut
the planar form into any shape for purpose of making the fits
against the area of treatment more comfortable. Perforations in the
material may act as a guide for cutting and users may save material
cut away from the planar form for later use in the same of
different context. The thickness of the material can vary from
thinner than 1 mm, to thicker than 25 mm, in order to provide
solutions for different treatment types. For example a wrap for a
wrist could be less than 5 mm thick, while the thickness for an
animal leg could be over 25 mm thick.
[0039] The invention also contemplates the implementation of
three-dimensional configurations molded to fit comfortably against
or around a body part. To provide compression to specific parts of
the body various shapes that conform to various appendages are
contemplated. An adaptation for example that is formed in the shape
of an open ended tube having a circumference that differs based on
the appendage for which the compressive bandage is to be used is
within the scope and spirit of the invention. The area targeted for
treatment generally dictates the shape and circumference of the
compressive bandage. A tube fitted to surround a part of a leg or
arm is for instance a different size depending upon whether the
tube is to be applied to an arm or leg. In cases where the target
for compression treatment is an ankle the shape of the tube may
take the form of a sock or other tubular type shape with a closed
or open end that surrounds the ankle region and provides the
desired compression and ability to apply varying temperatures to
the region under treatment by cooling or heating the material. The
sock may them be adapted for use in show, boots or other sports
related footwear that benefits by giving the wearer increased
padding, insulation and/or compression. The inner and outer
material of the sock may vary based on application so as to
minimize friction when putting the sock or tubular embodiment on
the wearer. A cloth, nylon or other material may surround the
elastomer itself so that the gel does not grip the footwear when
being inserted by the wearer. In other cases the elastomer is
incorporated into a sports related device such as a shoe, glove,
elbow pad, or kneepad and the material is one of multiple layers
where the layer in contact with the skin comprises a second
material designed to minimize friction when the wearer inserts or
removes an appendage.
[0040] Tubular shapes that conform to other appendages or regions
of the body in need of aerated compression, temperature change,
insulation and/or padding are also feasible and hence the invention
may be adapted for use to surround a finger, hand, wrist, elbow,
shoulder, knee, back or any other part of the body where
compressive treatment is desired. In one embodiment of the
invention a glove is made to fit around a subjects hand and provide
aerated compression and/or the ability to apply hot and/or cold
treatment to the subject's hand region while padding and insulating
the region. The material may also take a tubular shape that
functions as a sleeve for purposes of it being applied to a wrist
or elbow area. Tubular embodiments of the invention are generally
sized as appropriate for the intended appendage and may also
contain curvatures or inserts within the material to make the
bandage shapeable by the wearer to improve comfort and/or apply
more or less compression to an area. The insert may take various
forms that provide wearers with the ability to custom shape the
bandage for maximum comfort. For instance, a wire or flexible
plastic that wraps around the appendage may provide the mechanism
for changing the shape of the bandage to better conform with the
area of treatment. In other cases the material is used to improve
comfort for devices configured to restrict or immobilize a body
part such as a splint, brace, and/or cast. A sock shaped embodiment
has application for purposes of providing not only compression but
also insulation and padding when used in forms where the sock
surrounds an appendage or joint such as an ankle, wrist, elbow,
knee or fingers.
[0041] The planar or tubular forms of the device described herein
may be utilized in tandem with other treatments, devices or apparel
so as achieve improved comfort for the wearer. When sized
appropriately for a specific appendage the tubular shape can be
inserted into shoes, formed as a sock or used inside or in
conjunction with clothing apparel or sports devices for added
comfort and wearability. Utilizing the invention in tandem with
another method of treatment, such as a larger general purpose
bandage, or splint, that provides for the addition of compression
and thermal treatments is also contemplated. In this instance for
example the tubular embodiment of the invention could be integrated
into a bandage or splint so as to provide aerated compression to
the area of treatment. Also in one embodiment where the invention
is used in the lining of apparel, where the invention is removable
from apparel and can be adjusted for heat control but is then
reinserted via a holding mechanism such as a pouch, pocket, or
VELCRO.RTM. fastener. The material also has uses as a joint support
unit such as those used for sore elbows and knees to provide
compression, thermal treatment or comfort.
[0042] In one embodiment of the invention, the planar or tubular
form is composed of a biodegradable compound having a minimal or no
toxic effect. Reuse is possible simply by rewashing the material.
Storage is simplified because it is possible to keep the material
in the refrigerator or freezer, or stored at room temperature and
placed in ice water for quick preparation for cold pack treatment.
To use the material as a heat pack, a user may fill a hot bucket
with water and submerse the material into the water.
[0043] The planar or tubular form contains a set of interspersed
perforations 100 that can vary in size and quantity while still
providing some level of airflow to the area of treatment. For
instance, embodiments of the invention contemplate the use of
perforations placed closely or as far away from one another as the
particular application requires. Thus, the material may contain a
set of uniformly or non-uniformly spaced perforations that have
consistent or inconsistent diameters and proximity to one another.
FIG. 1 illustrates a set of uniformly spaced perforations having
consistent diameters whereas FIG. 2 illustrates a set of
non-uniformly spaced perforations 201, 202, 203 and 204 having
inconsistent shapes, sizes and locations. In instances where
aeration of the treatment area is paramount, the material may
contain bigger perforations than in instances where aeration is
less important. The perforations can also have varying shapes and
may, for instance, be geometric or customized to take advantage of
a particular niche market. In instances where the target market is
identifiable, the perforations may take any shape suitable for that
market. If, for example, the material was intended for use in a
children's hospital the perforations (and/or shape of the material
itself) may take the form of a popular cartoon or other such
character.
[0044] FIG. 3 shows an embodiment of invention configured to secure
the material into a fixed position over the treatment area or
extend the material to cover a larger surface area. For instance,
it is possible to fasten or hook the material into longer chains by
using snaps 502 that fit into perforations 501. The invention is
however not limited explicitly to the use of snaps and contemplates
the use of any other type of fastening device able to provide a way
to couple materials together or secure them in place over the
treatment area. In other instance, the securing mechanism provides
a way to consistently apply a certain amount of compression to the
treatment area.
[0045] Exemplary Methods of Use:
[0046] Embodiments of the invention are applicable for a wide
number of uses. Some, but not all of these uses are discussed below
for purposes of example. Since it is possible to manufacture the
invention in virtually any shape or size the material has
applicability in any instance where aeration, compression, padding,
insulation and/or cooling or heating of a surface area is desired.
A sunburned person, for instance, might use the material as a
blanket or for application to a specific body part that is
particularly sunburned. By placing the blanket-sized embodiment in
a freezer or refrigerator, users can cool the material and then
wrap it around the patient, thereby providing a soothing relief to
the painful effects of the burn.
[0047] An embodiment of the invention also has uses as a heat
source for someone suffering from cold exposure. For instance,
placing a blanket size embodiment in a tub of hot water can act as
a means for preheating the blanket prior to arrival of an exposure
victim. Once the victim arrives, users can remove the blanket sized
embodiment from the water, roll the blanket in a towel to dry it,
and wrap the blanket around the victim. Such an implementation
enables the victim's skin to breath while maintaining warmth.
Wrapping the victim inside a sleeping bag or towel provides further
insulation from any environmental temperature effects. It is also
possible to use the material to compression wrap injured limbs with
elements cut from the main blanket, or with independently heated or
cooled sections. By compressing the material over portions of the
body, direct contact of the heated bandage can quickly warm the
body and bring the victim out of shock.
[0048] FIGS. 7A-7D illustrate a tubular embodiment of the invention
for use in various contexts. The tubular embodiment of the
invention is configured for use to surround an appendage of a human
or animal for purposes of providing aerated compression, insulation
and/or padding. The perforations 701 provide increased airflow to
the area of treatment. The size of the tubular element is variable
depending on the wearer. To vary size tubes are made with different
circumferences determined based on the anticipated size of the
wearer and the specific appendage for which the device is intended.
To vary the size different circumference tubes may be manufactured
or the device may contain a sizing element 702 that enables it to
be adjusted based on the person or animal using the device. The
sizing element may take various forms in order to adjust the fit of
the tubular element. The sizing element may for instance, comprise
VELCRO.RTM. that surrounds the tube and when adjusted increases or
decreases the tightness of the device. The sizing element may also
use a mesh, wire, string or other such element embedded inside or
external to the tubular element that when pulled tight or relaxed
changes the circumference of the device.
[0049] FIGS. 7A-7D illustrate numerous views that show the material
as used in various contexts. FIG. 7A for instance shows the
material used in conjunction with a shoe. FIG. 7B, shows the
material used in conjunction with an ankle support. FIG. 7C
illustrates use in conjunction with a glove. FIG. 7D illustrates
the invention as a sock. The rectangular perforated portions
signify cuts to the shoes, ankle support and glove that may or may
not be utilized in the final product. In this manner, the final
product may have cut-away areas to increase air flow, or may not
have cut-away areas, in case the tubular embodiments reside out of
view, within the respective product.
[0050] FIG. 5 shows an embodiment of the invention which has use as
a saddle pad for horses and other animals. By cooling the pad
before placement under a horse saddle for instance, the pad can
provide a refreshing sensation to the animal. It is also possible
to wrap smaller pieces around an animal's leg, either after a race,
or after injury. FIG. 6 depicts an embodiment of the invention
configured as an equestrian leg wrap. The material is wrapped
around the treatment area after being cooled to a desired treatment
temperature. The material cools the treatment area while allowing
the animal to freely move. The area under the material is highly
aerated and this allows the animal to further cool itself via
evaporative cooling effects due to sweating. Also, the perforations
keep the material from sliding around by increasing the grip of the
material on the treatment area. The perforations further maintain
the grip by not allowing excess sweat to build up. The material
allows the horse to recover faster and this allows the animal to
undergo more frequent training sessions for longer periods of time.
In addition, the material absorbs impact and provides support for
tendons and joints in addition to acting as a cold compress.
[0051] FIG. 4 depicts an embodiment of the invention either cut
from a larger piece to fit the treatment area, or previously
manufactured in a smaller format and wrapped around a human wrist.
This embodiment provides a padding effect and is suitable for
someone with Carpal Tunnel syndrome or other forms of wrist
discomfort. When used in the manner depicted, the material cools
the wrist while simultaneously aerating and padding the wrist
thereby easing any discomfort suffered by the wearer. This
embodiment may take the form of a glove.
[0052] The material also has applications in other medical arenas
and can, for instance, provide a soothing compressive, yet aerating
wrap for limiting the amount of swelling and bruising caused after
surgery or other forms of injury.
[0053] Thus a thermal compressive aerating material and methods of
use relating to same is described. The claims, however, and the
full scope of any equivalents are what define the metes and bounds
of the invention.
