Abstract
A splint for use on a forearm, a wrist, and a hand of a user, including a rigid shell assembly with dorsal and a volar shell bodies, the dorsal and volar shell bodies each including a forearm portion, a wrist portion, and a hand portion. The dorsal and volar shell bodies are configured to releasably receive the forearm, wrist, and hand of the user therebetween. A dorsal compressible assembly and a volar compressible assembly extend along the inner surfaces of the dorsal and volar shell bodies, respectively. The volar compressible assembly includes an inflatable forearm bladder, an inflatable wrist bladder, and an inflatable hand bladder, each of which includes a valve to allow each of the inflatable bladders to be inflated independently of the other inflatable bladders.
Claims17
A splint for use on a forearm, a wrist, and a hand of a user, comprising:
- a rigid shell assembly including a dorsal shell body and a volar shell body, the dorsal shell body and the volar shell body each including a forearm portion, a wrist portion, and a hand portion, wherein the dorsal shell body and the volar shell body are configured to releasably receive the forearm, the wrist, and the hand of the user therebetween;
- a dorsal compressible assembly extending along an inner surface of the dorsal shell body, wherein the dorsal compressible assembly comprises an inflatable forearm bladder adjacent the forearm portion, an inflatable wrist bladder adjacent the wrist portion, and an inflatable hand bladder adjacent the hand portion;
- and
- a volar compressible assembly extending along an inner surface of the volar shell body, the volar compressible assembly including an inflatable forearm bladder adjacent the forearm portion, an inflatable wrist bladder adjacent the wrist portion, and an inflatable hand bladder adjacent the hand portion of the volar shell body,
- wherein each of the inflatable forearm bladder, the inflatable wrist bladder, and the inflatable hand bladder of the volar compressible assembly includes a respective valve to allow each of the inflatable forearm bladder, the wrist bladder, and the hand bladder to be inflated independently of the other inflatable bladders,
- wherein each of the inflatable forearm bladder, the inflatable wrist bladder, and the inflatable hand bladder of the dorsal compressible assembly includes a respective valve to allow each of the inflatable forearm bladder, the wrist bladder, and the hand bladder of the dorsal compressible assembly to be inflated independently of the other inflatable bladders of the dorsal compressible assembly, and
- wherein the dorsal compressible assembly further comprises a compressible material pad that extends along the inner surface of the volar shell body, wherein an outer surface of the compressible material pad abuts the inner surface of the dorsal shell body, and the inflatable forearm bladder, the inflatable wrist bladder, and the inflatable hand bladder are disposed on an inner surface of the compressible material pad.
A method of immobilizing a forearm, a wrist, and a hand of user, comprising the steps of:
- positioning a splint on the user, the splint comprising:
- a rigid shell assembly including a dorsal shell body and a volar shell body, the dorsal shell body and the volar shell body each including a forearm portion, a wrist portion, and a hand portion, wherein the dorsal shell body and the volar shell body are configured to releasably receive the forearm, the wrist, and the hand of the user therebetween;
- a dorsal compressible assembly extending along an inner surface of the dorsal shell body, wherein the dorsal compressible assembly comprises an inflatable forearm bladder adjacent the forearm portion, an inflatable wrist bladder adjacent the wrist portion, and an inflatable hand bladder adjacent the hand portion;
- and
- a volar compressible assembly extending along an inner surface of the volar shell body, the volar compressible assembly including an inflatable forearm bladder adjacent the forearm portion, and an inflatable wrist bladder adjacent the wrist portion of the volar shell body,
- wherein each of the inflatable forearm bladder, the inflatable wrist bladder, and the inflatable hand bladder of the volar compressible assembly includes a respective valve to allow each of the inflatable forearm bladder, the wrist bladder, and the hand bladder to be inflated independently of the other inflatable bladders,
- wherein each of the inflatable forearm bladder, the inflatable wrist bladder, and the inflatable hand bladder of the dorsal compressible assembly includes a respective valve to allow each of the inflatable forearm bladder, the wrist bladder, and the hand bladder of the dorsal compressible assembly to be inflated independently of the other inflatable bladders of the dorsal compressible assembly, and
- wherein the dorsal compressible assembly further comprises a compressible material pad that extends along the inner surface of the volar shell body, wherein an outer surface of the compressible material pad abuts the inner surface of the dorsal shell body, and the inflatable forearm bladder, the inflatable wrist bladder, and the inflatable hand bladder are disposed on an inner surface of the compressible material pad,
- wherein the splint is positioned on the user so that the inflatable forearm bladder and the inflatable wrist bladder of the volar compressible assembly are adjacent the forearm and the wrist of the user, respectively;
- inflating the inflatable forearm bladder to a first pressure;
- and
- inflating the inflatable wrist bladder to a second pressure,
- wherein the first pressure and the second pressure are not equal.
A splint for use on a limb of a user, comprising:
- a rigid shell assembly including a first shell body and a second shell body, wherein the first shell body and the second shell body are configured to releasably receive the limb of the user therebetween;
- a first compressible assembly extending along an inner surface of the first shell body;
- and
- a second compressible assembly extending along an inner surface of the second shell body, the second compressible assembly including a first inflatable bladder and a second inflatable bladder;
- wherein the first shell body is configured to receive a first side of the limb and the second shell body is configured to receive an opposite second side of the limb;
- wherein each of the first inflatable bladder and the second inflatable bladder includes a valve to allow each of the first and the second inflatable bladders to be inflated independently of the other inflatable bladder, and
- wherein the second compressible assembly further comprises a compressible material pad that extends along the inner surface of the second shell body, and
- wherein an outer surface of the compressible material pad abuts the inner surface of the second shell body, and wherein the first and second bladders are disposed on an inner surface of the compressible material pad.
