Abstract
Abstract An anatomical compression device including a flexible, expandible envelope which contains a pair of chemical agents which form a gas when mixed. In use, the envelope encircles a body part, such as an injured limb, and the chemical agents are mixed by manual manipulation of the envelope, creating a gas which expands the envelope and exerts a compressive force on the limb. The compression device can serve as a splint for broken bones, as a pressure dressing for the control of bleeding, or as a treatment device for minimizing the effect of snake venom or a snake bite victim.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
119 words
An anatomical compression device adapted to encircle and apply a compressive force to an anatomical body part, comprising: a completely sealed, flexible walled, expandible envelope adapted to at least partially encircle the body part; securing means for securing said envelope in an encircling relationship around the body part; and inflating means including a frangible member within said envelope for rapidly generating a supply of substantially only gas therein, said frangible member being accessible from the exterior of said envelope through the flexible walls thereof, whereby said frangible member may be manually ruptured to rapidly generate gas within said envelope, thereby causing said envelope to expand rapidly without further manipulation thereof and apply a compressive force to the body part.
Claim 2
Dependent Claim
119 words
An anatomical compression device adapted to encircle and apply a compressive force to an anatomical body part, comprising: a completely sealed, flexible walled, expandible envelope adapted to at least partially encircle the body part; securing means for securing said envelope in an encircling relationship around the body part; and inflating means including a frangible member within said envelope for rapidly generating a supply of substantially only gas therein, said frangible member being accessible from the exterior of said envelope through the flexible walls thereof, whereby said frangible member may be manually ruptured to rapidly generate gas within said envelope, thereby causing said envelope to expand rapidly without further manipulation thereof and apply a compressive force to the body part.
Claim 3
Dependent Claim
31 words
A compression device according to claim 1 wherein said securing means comprises a sleeve adapted to encircle the body part with said envelope disposed between said body part and said sleeve.
Claim 4
Dependent Claim
27 words
A compression device according to claim 1 wherein said securing means comprises first and second mating fastening elements affixed to said envelope adjacent two opposite edges thereof.
Claim 5
Dependent Claim
20 words
A compression device according to claim 3 wherein said fastening elements comprise the mating elements of a separable fabric fastener.
Claim 6
Dependent Claim
25 words
A compression device according to claim 3 or 4 wherein said envelope completely encircles the body part with said opposite edges thereof in overlapping relationship.
Claim 7
Dependent Claim
32 words
A compression device according to claim 1 or 3 for applying a compressive force to a human arm and wrist, wherein said envelope has a hole therethrough for receipt of the thumb.
Claim 8
Dependent Claim
24 words
A compression device according to claim 1 further comprising a pressure release valve communicating with the interior of said envelope for releasing gas therefrom.
Claim 9
Dependent Claim
41 words
A compression device according to claim 1 wherein said frangible member is a capsule containing a plurality of chemical ingredients capable of generating gas when mixed, said frangible member having at least one thin frangible partition wall separating said chemical ingredients.
Claim 10
Dependent Claim
41 words
A compression device according to claim 1 wherein said frangible member is a capsule containing a first chemical ingredient and said envelope contains a second chemical ingredient, with said first and said second chemical ingredients capable of generating gas when mixed.
Claim 11
Dependent Claim
17 words
A compression device according to claim 8 wherein said expandible envelope contains a plurality of said capsules.
Claim 12
Dependent Claim
25 words
A compression device according to claim 8 or 9 wherein at least one of said chemical ingredients contains an antifreeze agent for preventing freezing thereof.
Claim 13
Dependent Claim
21 words
A compression device according to claim 2 wherein said sleeve and said envelope are made of flexible, transparent plastic sheet material.
Claim 14
Dependent Claim
18 words
A compression device according to claim 1 wherein said envelope is made of flexible, transparent plastic sheet material.
Claim 15
Dependent Claim
113 words
An anatomical compression device adapted to encircle and apply a compressive force to an anatomical body part, comprising: a completely sealed, flexible walled, expandible envelope having a central space adapted to receive the body part with the envelope encircling the body part; and inflating means including a frangible member within said envelope for rapidly generating a supply of substantially only gas therein, said frangible member being accessible from the exterior of said envelope through the flexible walls thereof, whereby said frangible member may be manually ruptured to rapidly generate gas within said envelope, thereby causing said envelope to expand rapidly without further manipulation thereof and apply a compressive force to the body part.
Claim 16
Dependent Claim
113 words
An anatomical compression device adapted to encircle and apply a compressive force to an anatomical body part, comprising: a completely sealed, flexible walled, expandible envelope having a central space adapted to receive the body part with the envelope encircling the body part; and inflating means including a frangible member within said envelope for rapidly generating a supply of substantially only gas therein, said frangible member being accessible from the exterior of said envelope through the flexible walls thereof, whereby said frangible member may be manually ruptured to rapidly generate gas within said envelope, thereby causing said envelope to expand rapidly without further manipulation thereof and apply a compressive force to the body part.
Claim 17
Dependent Claim
41 words
A compression device according to claim 14 wherein said frangible member is a capsule containing a plurality of chemical ingredients capable of generating gas when mixed, said frangible member having at least one thin frangible partition wall separating said chemical ingredients.
Claim 18
Dependent Claim
41 words
A compression device according to claim 14 wherein said frangible member is a capsule containing a first chemical ingredient and said envelope containing a second chemical ingredient, with said first and said second chemical ingredients capable of generating gas when mixed.
Claim 19
Dependent Claim
17 words
A compression device according to claim 14 wherein said expandible envelope contains a plurality of said capsules.
Claim 20
Dependent Claim
25 words

Claim 21
Dependent Claim
18 words
A compression device according to claim 14 wherein said envelope is made of flexible, transparent plastic sheet material.
Claim 22
Dependent Claim
30 words
A compression device according to claim 14 for applying a compressive force to a human arm and wrist, wherein said envelope has a hole therethrough for receipt of the thumb.
Claim 23
Dependent Claim
24 words
A compression device according to claim 14 further comprising a pressure release valve communicating with the interior of said envelope for releasing gas therefrom.
