Various methods and systems are provided for controlling a supply of medical gas to a gas delivery system, such as an anesthesia machine, via a medical gas delivery module. In one example, a method includes supplying a medical gas from a pipeline gas supply source to a gas delivery system via a first conduit, measuring a quality of the medical gas in the first conduit, comparing the measured quality to an allowable range, switching to an alternative gas supply source for supplying the medical gas to the gas delivery system and communicating a pipeline gas supply fault in response to the measured quality being outside of the allowable range, and continuing supplying the medical gas to the gas delivery system from the pipeline gas supply source in response to the measured quality being inside of the allowable range.

A gas cylinder monitoring system comprising a gas cylinder for receiving and distributing gas. A flow control valve is associated with the gas cylinder and operable to allow or prevent the flow of gas from the cylinder. A monitor is provided for monitoring a signal from an input device associated with the flow control valve. The monitor has an environmental parameter sensor for detecting the presence or absence of a selected environmental parameter in the vicinity of the cylinder. The environmental parameter sensor is connected to the monitor for transmitting an environmental status signal thereto. A removable cover is provided for covering both the flow control valve and the environmental parameter sensor such as to only allow access to the flow control valve when the cover is removed. A transmitter is also provided for transmitting a signal, obtained by the monitor from the input device, to a receiver.

A nitric oxide delivery device including a valve assembly, a control module and a gas delivery mechanism is described. An exemplary gas delivery device includes a valve assembly with a valve and circuit including a memory, a processor and a transceiver in communication with the memory. The memory may include gas data such as gas identification, gas expiration and gas concentration. The transceiver on the circuit of the valve assembly may send wireless optical line-of-sight signals to communicate the gas data to a control module. Exemplary gas delivery mechanisms include a ventilator and a breathing circuit. Methods of administering gases containing nitric oxide are also described.

A cryostat arrangement includes a superconducting magnet to be cooled by an active cryocooler. The cryocooler includes a coolant circuit with a compressor, a cold head, and a cold finger in thermal contact with the magnet. A volumetric vessel containing cryogenic fluid is thermally coupled to the magnet. The volumetric vessel is connected to the coolant circuit by a pressure-resistant line. A fluidic component influences the flow rate through the line in a defined manner such that the cryogenic fluid flows between the volumetric vessel and the coolant circuit with a time constant of at least 15 minutes. The cryostat can be operated in a cryogen-free manner and permits a sufficiently long time to quench in the event of operational malfunctions.

A valve assembly comprising a housing and a valve, the valve being disposed within the housing, a first indexed member integral to the housing, the first indexed member adapted to be complementary to a second indexed member, and a radio frequency identification device adapted to communicate with a radio frequency receiver, the valve being configured to align with a canister, seal the canister and open in a single movement. A drug containment device having said valve assembly is also disclosed.

Methods, apparatus, and device, for a cryogenic storage system that stores and/or transports a liquid or gas at a temperature below ambient temperature. The cryogenic storage system has an enclosure assembly. The cryogenic storage system has a dewar that is positioned within the enclosure assembly. The enclosure assembly may comprise be configured to provide little to no friction between the dewar and the enclosure assembly. The enclosure assembly may be configured for shock absorption and/or vibration damping for the dewar during transferring of the cryogenic storage system.

A cryogenic medical device for delivery of subcooled liquid cryogen to various configurations of cryoprobes is designed for the treatment of damaged, diseased, cancerous or other unwanted tissues. The device is a closed or semi-closed system in which the liquid cryogen is contained in both the supply and return stages. The device is capable of generating cryogen to a supercritical state and may be utilized in any rapid cooling systems. As designed, the device comprises a number of parts including a vacuum insulated outer dewar, submersible cryogen pump, baffled linear heat exchanger, multiple pressurization cartridges, a return chamber, and a series of valves to control the flow of the liquid cryogen. The cryogenic medical device promotes the subcooling to any external cryogenic instrument.

A modular shipping system includes a bulk shipping space; and a base to support a pair of stackable cryogenic shipping subunits positioned in the bulk shipping space during long distance shipment, each subunit having a plurality of feet on a subunit bottom adapted to rest above a plurality of corresponding foot receptacles on a subunit lid, each subunit having its own cryogen connection source to maintain temperature during transit.
