Therapeutic elastic bandage
Abstract
An elastic bandage having spaced transverse pockets into which
bags of latex or similar material are insertable. The bags are
elastic and flexible. They are filled, air free, with an
anti-freeze solution such as propylene glycol in distilled water.
The preferred ratio is a 10 percent solution. This provides an
unfrozen slush when the bandage is refrigerated to -10.degree.C..
The spaced pockets provide a regular articulation which gives the
bandage flexibility when it is wrapped around a limb. The pockets
are adjacent one end of the bandage and the remainder of the
bandage can then be wrapped around the pockets to provide
insulation and pressure on the affected site. The bandage is thus
suitable for humans and animals such as horses. The pockets and
bags can also be incorporated into elastic elbow, knee, ankle or
other specialized bandages. If it is desired to apply heat instead
of cold, the same construction can be used except that the bags can
now be filled with a heat retaining agent such as sand.

Claims
We claim:
1. A therapeutic elastic bandage for cold or heat treatments
comprising an elastic bandage formed of textile covered elastic
threads and having a plurality of spaced pockets, an elastic
flexible latex bag positioned in each of said pockets, and a
filling in said bags for providing cold or heat.
2. An elastic bandage as in claim 1, wherein said bandage is shaped
to fit over an ankle and is provided with circular pockets to fit
over the ankle malleolus.
3. An elastic bandage as in claim 1, wherein said bandage is shaped
to fit over a knee or elbow joint.
4. An elastic bandage as in claim 1, wherein said bags are filled
with a cold retaining material, said material comprising a solution
of propylene glycol in distilled water.
5. An elastic bandage as in claim 4, wherein said propylene glycol
is in a 10 percent solution whereby said solution will turn to
slush when refrigerated to -10.degree. C.
6. An elastic bandage as in claim 1, wherein said bags are filled
with a heat retaining material, said material comprising sand.
Description
BACKGROUND OF THE INVENTION
The therapeutic effect of ice packs or hot water bottles on certain
types of strains and injuries is well known to physicians and
athletic trainers of humans and animals. Also, elastic bandages are
used to apply a therapeutic pressure and support to strained
ligaments, muscles, etc., and as an aid in reducing or preventing
edema. These two aids have heretofore been used separately. Ice
packs or heat is applied as an emergency measure in many instances,
the affected limb is then bandaged with an elastic bandage, such as
an "Ace" bandage, to allow for mobility and support. The patient
then can move about with the bandage in place only after the
treatment with the cold or heat is finished.
SUMMARY OF THE INVENTION.
The present invention combines the cold or heat treatment with the
elastic bandage so that the therapeutic effect of each can be
applied simultaneously while permitting the patient to move about
freely. The basic invention involves an elastic bandage, such as an
"Ace" bandage, provided adjacent one end with spaced, transverse
pockets. Elongated bags of latex or similar material are positioned
in the pockets. Each bag is filled with a solution of propylene
glycol, or other suitable anti-freeze, to inhibit freezing at low
temperatures. It is contemplated that the bandage will be
refrigerated before use to -10.degree.C., turning the solution to a
slush. When the bandage is applied to a limb, the spaced pockets
remain flexible and can be firmly wrapped, the rest of the bandage
holding the pockets firmly and supplying insulation and support.
Elastic bandages with similar pockets and bags can be provided for
elbow, knee, ankle or other specialized bandages. If heat is
required rather than cold, the bags can be filled with sand or
other heat retaining agent, and the bandage can be heated prior to
its application.
DESCRIPTION OF THE DRAWINGS
In the drawings:
FIG, 1 is a plan view, partly broken away, of an elastic bandage
embodying our present invention;
FIG. 2 is a section taken on line 2--2 on FIG. 1;
FIG. 3 is a perspective view of an elastic bandage for an ankle
embodying our present invention; and
FIG. 4 is a perspective view of an elastic elbow or knee bandage
embodying the present invention.
DESCRIPTION OF THE INVENTION
Referring more in deatil to the drawings, FIG. 1 illustrates an
elastic bandage 10, similar to the well-known "Ace" bandage. The
bandage 10 is provided adjacent one end with a plurality of spaced,
transverse pockets 12. In the illustrated form, the pockets 12 are
formed by folding back a portion of the bandage 10 and stitching
along the lines 14 to form the spaced pockets. We now provide an
elongated bag 16 which should be flexible and elastic. While
plastic materials can be used, we prefer latex to provide the
necessary flexibility and elasticity. In FIG. 1 eight bags are
illustrated. However, the pockets 12 may be left open at one end
and the bags 16 can be inserted before use in the required number
to cover a small or large area.
Each bag 16 is filled, air free, with a solution of propylene
glycol in distilled water 18, in a solution of approximately 10
percent. If desired, any other suitable anti-freeze can be
substituted. Clear water will freeze solid and flexibility must
then be provided by the articulation of the spaced pockets. It is
therefore preferred that the bags 16 be not frozen solid. With the
anti-freeze, the bandage is placed in a freezer and cooled to
approximately -10.degree.C. At this temperature the solution should
turn to slush and still be fairly flexible. The pocketed end of the
bandage 10 is wrapped about the limb and then the rest of the
bandage is wrapped to provide support and insulation. The safe
cooling temperature is 6.5.degree.C. or 43.degree.F. The bandage of
the present invention cools from 7.degree.C. to 23.degree. C. which
it reaches in approximately one hour. The upper limit of heat
treatment is 44.degree.C. or 111.2.degree.F.
FIG. 3 is the application of the invention to an ankle bandage. The
bandage 20 is of a conventional shape to receive a person's foot
and is provided with a circular pocket 22 on each side surrounding
the ankle malleolus. This provides therapy for a sprained ankle. If
desired, additional pockets can be provided at 24 extending
vertically in spaced relation around the top edge of the bandage.
Also, additional pockets 26 can be added across the instep.
Additional elastic bandage may be used to wrap the bandage 20, or
the bandage 20 may be integrally provided with a length of wrapping
bandage.
The form shown in FIG. 4 provides the same therapy for a joint such
as a knee or elbow. Here the bandage 28 is provided with the
articulated pockets 30 in short lengths for flexibility. Again, as
in the form shown in FIG. 3, additional lengths of bandage may be
added for support and insulation. The pocketed construction can
thus be applied to other specialized bandages for any other part of
the body.
All of the above forms may be used for applying heat treatments by
filling the bags with a heat retaining element and warming the
bandage in advance of use. Sand makes a good heat retaining
element. The bags can be used with chemicals for producing cold by
an endothermic reaction. Various chemicals such as ammonium nitrate
in water will produce an initial cooling effect. Similarly, warmth
can be provided with an exothermic reaction. This can include
chemicals such as calcium chloride in water. The reactions
producing these cold and hot temperatures are short lived. However,
the bandage wrapping acts as insulation to prolong the effect.
The bandage of the present invention thus provides many advantages
over an ice pack treatment followed by a wrap with an elastic
bandage. It stays cold for a comparatively long period and stays in
position even during physical movement. It is comfortable and easy
to apply and remove. It stays dry, there being no condensation. It
assumes the configuration of the desired anatomical area and
expands and contracts to provide localized application. The
elasticity of the bandage and the pockets provides pressure to
prevent edema in many cases and simultaneously supports the area.
And it can be used over again. Furthermore, it is applicable to
humans and animals such as horses.
Other advantages of the present invention will be readily apparent
to a person skilled in the art.
