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.

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.

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.

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.

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.
摘要:
A first strand of interconnected hollow polymeric chambers is connected to a second strand of interconnected hollow polymeric chambers. A connecting portion of the first strand has an outer surface contour conforming to a portion of the inner surface of a chamber. A partial chamber is formed on the end of the second strand, the partial chamber having an inner surface that conforms to the outer surface of the connecting portion. The connecting portion is inserted into the partial chamber and the two strands are held together by adhesive.

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 vessel may be formed in a variety of useful shapes and the tubes may have various internal and external cross-sections. The end caps may be filled with sintactic foam with canals leading to the passageway. Microtubes through the syntactic foam may connect the tubes to the passageway. The vessel is further strengthened by overwrapping with high-strength braiding material, hoop winding or by overlayment with high-strength fabric. The vessel is further strengthened by coating with plastic resin. Apparatus and methods for forming the cellular reservoir flexible vessels are described.

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.
