Abstract: A knee orthosis device contains a bladder capable of sequential or cyclical compression of at least two inflatable chambers. An optional gel pack may be removably affixed to an inside surface of the bladder for providing cold therapy to a user. The wrap is preferably provided with removable and relocatable hinge bars. The hinge bars preferably are provided with conjular pads. The hinge bars may be located with the assistance of locating indicia and installed and affixed within the device and affixed at a desired location on an inside surface of the bladder so that the hinges of the hinge bars are positioned over a transverse axis of a user's knee, thereby ensuring that the knee wrap device of the invention provides a universal fit.

Abstract: A compression therapy system for treating deep vein thrombosis in disclosed. The system provides sequential, graduated compression to a selected limb or body part. The system includes a portable compression device having multiple outlets. In one embodiment, up to three outputs may be selectively activated by a user. The wraps may be provided with cold therapy wraps. In a second embodiment, the system utilizes a timer to determine which, if any, of several wraps may be attached and inflates a detected wrap to a correct pressure or powers off the system as may be appropriate.

Abstract: Biohazardous needles, in one embodiment, are destroyed by the application of an electrical arc that progressively destroys the needle and seals hollow needles. An elongated electrode that slopes up and away from the needle supports is used to strike and then progressively support the destructive arc. In another embodiment, an electrical arc is used to blunt the sharp end of the needle by melting it and allowing it to solidify into a spherical cap.
