Abstract:
A transport unit includes a plurality of permanent magnets arranged to provide a magnetic holding field for protecting hyperpolarized gas during storage and/or transport. The permanent magnets are configured in a relatively light weight manner to project a substantially cylindrical magnetic holding field or spherical holding field in space. The magnet arrangements can include primary magnets and field shaping secondary magnets which act to enlarge the region of homogeneity. The permanent magnet arrangement can also be provided with a cylindrical shaped flex sheet magnetically activated to provide the magnetic holding field. The permanent magnet arrangements do not require disassembly to insert or remove one or more containers of hyperpolarized gas in or out of the transport unit.
Abstract:
A resilient multi-layer container is configured to receive a quantity of hyperpolarized noble fluid such as gas and includes a wall with at least two layers, a first layer with a surface which minimizes contact-induced spin-relaxation and a first or second layer which is substantially impermeable to oxygen. The container is especially suitable for collecting and transporting He. The resilient container can be formed of material layers which are concurrently responsive to pressure such as polymers, deuterated polymers, or metallic films. The container can include a capillary stem and/or a port or valve isolation means to inhibit the flow of gas from the main volume of the container during transport. The resilient container can be configured to directly deliver the hyperpolarized noble gas to a target interface by deflating or collapsing the inflated resilient container. In addition, single layer resilient containers with T1's of above 4 hours for Xe and above 6 hours for He include materials with selected relaxivity values. In addition, a bag with a port fitting or valve member and one or more of a capillary stem and port isolation means is configured to minimize the depolarizing effect of the container valve or fitting(s). Also disclosed is a method for determining the gas solubility in an unknown polymer or liquid using the measured relaxation time of a hyperpolarized gas.
Abstract:
An orientation independent delivery device (100). The delivery device (100) includes a gas chamber, a delivery chamber, a gas cell (110), and a delivery aperture (112). The gas chamber includes a gas-side rigid portion (102) and a gas-side flexible barrier (104). The gas-side flexible barrier (104) is sealed to the gas-side rigid portion (102). The delivery chamber includes a delivery-side rigid portion (106) and a delivery-side flexible barrier (108). The delivery-side flexible barrier (108) is sealed to the delivery-side rigid portion (106) and is oriented adjacent to the gas-side flexible barrier (104). The gas cell (110) is coupled to the gas-side rigid portion (102) of the gas chamber. The gas cell (110) increases a gas pressure within the gas chamber to expand the gas-side flexible barrier (104). Expansion of the gas-side flexible barrier (104) applies a compressive force to the delivery-side flexible barrier (108) allowing a delivery material to escape from the delivery chamber.

Gasspeicher (10) mit einem inneren Gasspeicher-Sack (29), der einen mit Gas befüllbaren Gasspeicherraum (12) ausbildet, und einer den Gasspeicher-Sack (29) bereichsweise umgebenden Außenmembran (1), wobei der Gasspeicher-Sack (29) und die Außenmembran (1) gegenüber einer Bodenfläche (4) festgelegt sind, wobei der Gasspeicher-Sack (29) an seiner Außenseite zumindest eine Lasche (20, 20', 20", 20"', 20"", 20'"") aufweist, welche zumindest teilweise gemeinsam mit einem Randbereich der Außenmembran (1) geklemmt ist, und dass die gemeinsame Klemmung gegenüber der Bodenfläche (4) fixiert ist.
Abstract:
A multilayered pressure vessel (10) fabricated from at least one single ply sheet of flexible material (100) having an approximate longitudinal midline which divides the material into an inner portion (130) having an inner surface, an outer surface, an edge, a seam allowance, and a width, and an outer portion having an inner surface, an outer surface, an edge, a seam allowance, and a width. The width of the outer portion (120) is greater than the width of the inner portion (140). A primary seam (250) binds the outer portion and the inner portion to the material sheet at the midline proximate the outer portion edge and inner portion edge. The sheet (100) is wrapped into a continuous substantially 720 degree wrap to form a generally cylindrical vessel body having possible multiple fluid passageways, at the election of the user. The primary seam (250) is concealed.

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:
The present invention relates to a covering for a gas storage (100). The covering comprises an exterior membrane (101) for at least partially enveloping a storage volume (Vs) of the storage (100), wherein the exterior membrane (101) is made of an elastomeric material, so that a shape and an area size of the exterior membrane (101) is adaptable to a pressure of the gaseous medium in the storage volume (Vs). The storage (100) further comprises a support structure mounted over the exterior membrane (101) in such a way that a) if a first pressure value in the storage volume (Vs) is reached, a first portion (111) of the exterior membrane (101) contacts the support structure in a force transmitting manner and a second portion (112) of the exterior membrane (101) is contact-free with the support structure, and b) if a critical pressure value storage volume (Vs) is reached, at least one of the support structure and the exterior membrane (101) fails, wherein if the critical pressure value in storage volume (Vs) is reached, the second portion (112) is expandable such that a contribution (Va) to the storage volume (Vs) of at least 10% in comparison to the volume of the storage volume (Vs) with the first pressure value is generated.
