摘要： A double walled nonpressurized cryogenic storage container having an elongated neck tube in combination with a closure assembly for the neck tube. The closure assembly includes a neck plug and a neck tube adapter having access means for sensor and fill lines. The neck tube adapter has an outer shell and an inner shell with a multiplicity of radially projecting spacer elements for establishing an annular space between the outer shell and the neck tube. The inner shell is preferably eccentric to the outer shell.

摘要： An oxygen-delivery system comprises a portable oxygen meter including a low-pressure oxygen inlet, a low-pressure oxygen outlet, and an exhale-inhale sensing port, an oxygen-supply source including a discharge outlet and configured to discharge low-pressure oxygen through the discharge outlet, a flexible supply tube arranged to conduct low-pressure oxygen from the oxygen-supply source into the portable oxygen meter through the low-pressure oxygen inlet, and a nasal cannula coupled to the low-pressure oxygen outlet and the exhale-inhale sensing port. The portable oxygen meter further includes a pneumatic demand oxygen conserver including a diaphragm valve member, control means coupled to the exhale-inhale sensing port for causing the diaphragm valve member to move to a flow-delivery position in response to inhalation of a patient and to a flow-blocking position in response to a lack of inhalation by the patient during exhalation through the nasal cannula, and an oxygen flow passage arranged to pass low-pressure oxygen through an oxygen flow-metering aperture to meter low-pressure oxygen outlet at a selected oxygen flow rate. The oxygen-delivery system further comprises a mount including a flange coupled to the portable oxygen meter and a clip adapted to be coupled to an item of clothing worn by the patient.

摘要： An apparatus is provided for controlling discharge of oxygen from an oxygen supply source to a patient. The apparatus includes an oxygen supply inlet, a pressure regulator coupled to the oxygen supply inlet and configured to reduce pressure of oxygen received from the oxygen supply inlet to a selected magnitude, a flow controller coupled to the pressure regulator and configured to meter oxygen received from the pressure regulator at a selected flow rate, and an oxygen distribution assembly including a pneumatic demand oxygen valve and a conduit conducting oxygen discharged from the flow controller through the pressure regulator to the pneumatic demand oxygen valve for delivery to a patient. The flow controller includes a chamber and a rotary valve for splitting oxygen discharged from the chamber into a first stream in an oxygen supply passageway for use by a patient and a second stream in a diaphragm supply passageway for controlling operation of pneumatic demand oxygen valve.
