Abstract
A compression device for human limbs including a flexible sleeve and an expandible envelope which contains a pair of chemical agents which form a gas when mixed. In use, the chemical agents are mixed by manual manipulation of the expandible envelope, creating a gas which expands the envelope causing the envelope and the sleeve to bear against and to support an injured limb which has been inserted into the sleeve, thereby serving as a splint for broken bones or as a pressure dressing for the control of bleeding. The device may comprise a sleeve surrounding the injured limb and the envelope or, alternatively, a flexible panel forming a sleeve-like opening in which the limb is inserted.
Claims9
A compression device for human limbs comprising an open ended tubular sleeve member having an interior space sized for receiving a human limb, an expandible envelope disposed within said tubular sleeve member at one side of said interior space and opposite to a wall portion of said sleeve member, with said human limb being receivable in said interior space between said expandible envelope and said wall portion, said expandible envelope having flexible walls, being completely sealed, and having a normal collapsed condition in which said expandible envelope occupies a minor portion of said interior portion of said interior space of said sleeve member, and means including a frangible member within said expandible envelope for rapidly generating a supply of substantially only gas therein, said frangible member being accessible from the exterior of said sleeve member, through said flexible walls of said expandible envelope, whereby said frangible member may be manually ruptured to rapidly generate gas within said expandible envelope, thereby causing said expandible envelope to expand rapidly without further manipulation thereof and press a limb inserted into said interior space against said wall portion of said sleeve member.
