Abstract:
A wearable storage system for pressurized fluid includes a pressure 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 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. 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.

A portable pressurized gas assembly which comprises a first panel structure; first looping pipe coil structure carried by the panel structure in overlying relation to the structure and having flexible construction, there being structure rigidly attaching the pipe coil structure to the panel structure at one side thereof; the looping coil structure having pressurized gas inlet and outlet fittings associated therewith, whereby the looping pipe coil structure may receive pressurized gas for transport by a user; the panel structure and pipe coil structure having an overall length dimension less than about 12 inches and overall width dimension less than about 9 inches.
Abstract:
An infant carrier device adapted to be worn on the upper torso of a wearer to position the infant in front of the wearer comprising a support frame having a first end and an opposite second end, bifurcated shoulder support members extending from the support frame first end to position the carrier about the upper torso of a wearer and a seat member secured to the support frame second end to receive and support an infant or small child.
Abstract:
An articulated firefighter breathing pack includes multiple polymeric pressure vessels connected together and to a flexible manifold with sections of flexible conduit. The pressure vessels and sections of flexible conduit are encased in high strength fiber material. The pressure vessels are wrapped in high strength ballistic ribbon material. The manifold provides connections for a high pressure regulator and an air fill source. A low pressure hose is connected to the high pressure regulator, a low pressure regulator is connected to the low pressure hose and a mouthpiece connected to the low pressure regulator. A pressure vessel container attaches the pressure vessels, the flexible conduit and the manifold to a harness having a waist portion and two vertical straps extending upwardly over the shoulders and back down to the waist portion. A utility belt provides mounting for equipment for the breathing pack including hoses, a power supply, electronic sensors and controls.
Abstract:
A cellular reservoir flexible pressure vessel is formed as a series of closely packed tubes fitted into a pair of opposing end caps. The end caps have individual receptacles sized and shaped to receive the tube ends that are secured with adhesive or radio frequency welding. At least one end cap has a passageway for connection of the vessel. The flexible pressure vessel has a pressure relief device comprising a reduction in thickness of one end cap at a predetermined location. When subjected to overpressure it fails at the predetermined location. Other pressure relief devices include: a projecting member on the vessel surface, a weakened section of the passageway, a weakening or an absence of braiding material or hoop winding at a predetermined location on the vessel surface or along the passageway, a weakening or spreading of fibers in either the reinforcing panels or the flexible blankets covering the vessel.
Abstract:
An ovoid flexible pressure vessel is described. At least one hollow pressure cell, formed of resilient material, a passageway, a valving means, a capillary tube, hoop winding, high-strength braiding material and at least one reinforcing ring are provided. The ovoid flexible pressure vessel has a pressure relief device comprising a reduction in thickness of the hollow pressure cell at a predetermined location whereby, when the hollow pressure cell is subjected to an overpressure condition it will fail at the predetermined location. Further pressure release devices include the following: a reduction in thickness of the cell, an indentation, a projecting member, a weakened section of the passageway, a weakening or an absence of high-strength braiding material or hoop winding at a predetermined location along the passageway, a weakening or spreading of fibers in either of the reinforcing panels or in either flexible blankets.
Abstract:
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.

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.
Abstract:
A fluid transfer control valve is connected to a pressure vessel formed from a plurality of hollow, polymeric chambers interconnected by polymeric conduit sections disposed between adjacent ones of the chambers. The valve includes a valve body and a pressure relief mechanism attached to the body. The pressure relief mechanism is operative to release pressure from the pressure vessel when the pressure within the vessel exceeds a predetermined maximum pressure. In a preferred embodiment, the relief mechanism comprises a rupture disk. The pressure relief valve may also include a filter element disposed along a fluid flow path defined within the valve body and/or a restrictive flow path for reducing the pressure of fluid flowing through the valve body.
