CA 2411527

A wearable storage system (10) for pressurized fluid includes a pressure vessel (40) formed from a plurality of polymeric hollow chambers (50) having either an ellipsoidal or spherical shape and interconnected by a plurality of relatively narrow conduit sections (52, 56) disposed between consecutive ones of the chambers. The pressure vessel includes a reinforcing filament (46) 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 (76) attached to the pressure vessel for controlling fluid flow into and out of the pressure vessel. A gas delivery mechanism for delivering gas stored in the pressure vessel to the patient in a controlled manner is connected to the fluid transfer control system. The pressure vessel and the fluid transfer control system are incorporated into a wearable garment to provide an ambulatory supply of gas for the patient.

L'invention concerne un système de stockage (10) portable de fluides sous pression, qui comporte un récipient (40) sous pression constitué de plusieurs chambres (50) creuses polymères de forme ellipsoïdale ou sphérique et reliées par plusieurs tronçons de conduits (52, 56) relativement étroits placés entre des chambres consécutives. Le récipient sous pression comprend un filament (46) de renforcement enroulé autour des chambres interconnectées et reliant les tronçons de conduits afin de limiter la dilatation radiale des chambres et desdits tronçons lorsqu'ils sont remplis d'un fluide sous pression. Le système conteneur comprend en outre un système de régulation (76) de transfert de fluide, fixé au récipient sous pression, destiné à réguler l'écoulement du fluide dans ledit récipient et hors de ce dernier. Un dispositif de distribution de gaz, conçu pour administrer le gaz stocké dans le récipient sous pression au patient de manière contrôlée, est relié au système de régulation de transfert de fluide. Le récipient sous pression et ledit système sont incorporés dans un vêtement portable conçu pour fournir de manière ambulatoire du gaz au patient.
