WALKING ASSISTANCE DEVICE INCORPORATING GAS STORAGE VESSEL COMPRISING A POLYMERIC CONTAINER SYSTEM FOR PRESSURIZED FLUIDS |
摘要 |
A walking assistance device, for example, a walking cane, a walking crutch, or walker includes a gas storage vessel for providing an ambulatory supply of medicinal gas for a user of the device. The gas storage vessel is formed from a plurality of polymeric hollow chamber having either an ellipsoidal or spherical shape and interconnected by a plurality of relatively narrow conduit sections disposed between consecutive ones of the chambers. The gas storage vessel includes a reinforcing filament wrapped around the interconnected chambers and interconnecting conduit sections to limit radial expansion of the chambers and conduit sections when filled with a fluid under pressure. The container system further includes a fluid transfer control system attached to the gas storage vessel for controlling fluid flow into and out of the gas storage vessel and a gas delivery mechanism for delivering gas from the gas storage vessel to a user in a breathable manner. |
