Title:
WHEELED PERSONAL TRANSPORT DEVICE INCORPORATING GAS STORAGE VESSEL COMPRISING A POLYMERIC CONTAINER SYSTEM FOR PRESSURIZED FLUIDS
Document Type and Number:
WIPO Patent Application WO2002037018
Kind Code:
A9
Abstract:
A wheeled personal transport device, for example, a wheelchair, includes a pressure vessel for providing a portable supply of medicinal gas for a user of the transport device. The pressure vessel is formed from a plurality of polymeric hollow chamber having either en ellipsoidal or spherical shape and interconnected by a plurality of relatively narrow conduit sections disposed between consecutive ones of the chambers. The pressure 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 pressure vessel for controlling fluid flow into and out of the pressure vessel and a gas delivery mechanism for delivering gas from the pressure vessel to a user in a breathable manner.
