Abstract: A clamp, and method, for occluding bodily vessels such as arteries and veins, is provided. The clamp comprises a flexible hollow catheter having a pair of inflatable balloons sealed to the catheter and in fluid communication with its interior. The balloons are separated by a predetermined distance along the catheter such that when the catheter is secured around a vessel, the balloons present substantially parallel, opposed and spaced occluding surfaces at substantially opposite sides of the vessel. Lateral expansion spaces also are formed into which the compressed vessel wall expands as the vessel is compressed when the balloons are inflated by a fluid introduced through the catheter.

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.

Abstract: An infusion system with a self-generating pressure assembly includes a flexible infusion container which contains a fluid, such as blood and an expandible envelope which contains a pair of chemical agents which generate a gas when mixed. In use, the chemical agents are mixed by manual manipulation of the expandable envelope, creating a gas which expands causing the expandible envelope to bear against the flexible infusion container creating fluid pressure therein which causes the infusion fluid to flow out of the infusion container. The assembly may comprise a sleeve surrounding both the infusion container and expandible envelope, or a flexible panel secured to the side edges of the expandible envelope and forming a sleeve-like opening into which the infusion container is inserted.

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.
