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.

1. A wheeled personal transport device providing a portable supply of medicinal gas comprising:a seat adapted to support a user in a seated position, said seat including a bottom panel for supporting the user seated thereon; a support structure constructed and arranged to support said seat in a raised position with respect to the ground; wheels mounted on said support structure for rolling contact with the ground to permit said support structure and said seat with a user supported thereby to be rollingly transported along the ground; and a gas storage vessel carried on said seat, said gas storage vessel comprising: a plurality of hollow chambers, each having a substantially spherical or ellipsoidal shape and being formed from a polymeric material; a plurality of conduit sections formed from a polymeric material, each being positioned between adjacent ones of said plurality of hollow chambers to interconnect said plurality of hollow chambers, each of said conduit sections having a maximum interior transverse dimension that is smaller than a maximum interior transverse dimension of each of said hollow chambers; and a reinforcing filament wrapped around said hollow chambers and said conduit sections, wherein said gas storage vessel further comprises at least one continuous strand of interconnected ones of said plurality of chambers spaced apart by ones of said plurality of conduit sections, said continuous strand being carried on said bottom panel arranged in a configuration conforming to said bottom panel.
