Abstract:
A litter for carrying a patient in a supine position, such as a stretcher or trauma board, includes a support panel and a pressure pack for providing a portable supply of medicinal gas, such as oxygen, that can be administered to a patient on the liter. The pressure pack includes a gas storage vessel 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 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 storage vessel further includes a fluid transfer control system attached to the storage vessel for controlling fluid flow into and out of the pressure vessel and a gas delivery mechanism for delivering gas from the storage vessel to a user in a breathable manner.
Abstract:
A vehicle includes a storage pack for storing gas under pressure for providing an onboard supply of the pressurized gas. The pressurized gas may be used as a medicinal gas, e.g. oxygen, on emergency medical vehicles, or the gas may be used as a fuel source for a motorized vehicle having a motor that runs on combustible gas. The gas storage pack includes a pressure vessel formed from a plurality of hollow chambers, which have either an ellipsoidal or spherical shape, 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 gas storage pack further includes a gas transfer control system attached to the pressure vessel for controlling gas flow into and out of the pressure vessel.
Abstract:
A pressurized gas supply system includes a pressurized container which expands and contracts. The container includes a one-piece liner molded from a polymer which is reinforced by a high tensile fiber such as KEVLARnull. A valve is molded into the liner, and a regulator is connected to the valve. A hose, having a conserver positioned therealong, extends between the regulator and a fitting allowing a user to inhale gas from the container. The container is carried in a carrying bag, which can be in the form of a carrying case, a purse, or a back-pack.
Abstract:
A compact portable transport unit for shipping hyperpolarized noble gases and shielding same from electromagnetic interference and/or external magnetic fields includes a means for shifting the resonance frequency of the hyperpolarized gas outside the bandwidth of typical frequencies associated with prevalent time-dependent fields produced by electrical sources. Preferably the transport unit includes a magnetic holding field which is generated from a solenoid in the transport unit. The solenoid includes a plurality of coil segments and is sized and configured to receive the gas chamber of a container. The gas container is configured with a valve, a spherical body, and an extending capillary stem between the valve and the body. The gas container or hyperpolarized product container can also be formed as a resilient bag. The distribution method includes positioning a multi-bolus container within the transport unit to shield it and transporting same to a second site remote from the first site and subsequently dispensing into smaller patient sized formulations which can be transported (shielded) in another transport unit to yet another site.
Abstract:
Plastic articles made of ionomeric modified poly-ether-ester are stored in a cryogenic fluid containing receptacle. The articles may be tubing or bags or articles of surgical equipment or clothing.
Abstract:
An offshore submarine storage facility for highly chilled liquified gas, such as liquified natural gas, is disclosed. The facility includes an elongated, vertically oriented submerged frame. An insulated storage tank is movably mounted to the frame so as to be positionable at various depths in the water. The tank is constructed to transfer external ambient water pressure to the liquified gas without intermixture. This transferred pressure aids in maintaining the liquified state of the stored liquified gas.
