Abstract
A gas generating inflation device utilizing combustible propellant cartridges is provided for a pneumatic orthosis used by persons needing support of the legs or lower body and legs. Since most such persons use two canes for additional support while standing or walking, the inflation device is conveniently located in one of the canes, with the other cane used as a supply container for additional cartridges. The gas generator is loaded with a propellant cartridge and gas generation is initiated at the will of the orthosis wearer, the generated gas then flowing through filters in the cane in which the generator is located and thence into the pneumatic orthosis to inflate it.
