A gas delivery system including a gas delivery device, 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 gas are also described.

A transport means (N) includes at least one lower support (1) on which at least two cylinders, in which a material which can be a compressed gas is stored, are placed by being stacked on the top of one another; at least one body (3) having one end connected to said lower support (1); at least one first steering element (2a) disposed on the body (3) for steering the cylinders during transport, at least two motion elements (4) connected to said body (3) for providing the movement of the transport means (N), the transport means (N) including at least one thrust mechanism which allows the topmost cylinder to move closer toward the lower support (1) such that the cylinders stacked on the top of one another do not come apart during transport.

A storage tank includes a frame, tank assembly, and scrubber system. The tank assembly including a vessel supported by the frame and having a first end, a second end, and a sidewall extending from the first end to the second end. The vessel further has a top, a bottom, at least one side, an internal surface, and an outlet fluidly coupled with the bottom. A scrubber tank is supported by the frame and fluidly connected to the top of the vessel to receive vapors from the vessel in a way that when a vapor absorption material is disposed in the scrubber tank, the vapors pass into the vapor absorption material.

A cryogenic system as well as a method of generating a pressurized, sub-cooled mixed-phase cryogen and a method of delivering such a cryogen to a cryoprobe are disclosed. In an embodiment, the cryogenic system includes a reservoir containing a liquid cryogen and a sub-cooling coil immersed in the liquid cryogen. The cryogen is supplied to the sub-cooling coil and is cooled under pressure to produce a pressurized mixed phase cryogen within the sub-cooling coil. This pressurized mixed phase cryogen is provided via supply line to a cryo-device for use.

Various cryogenic fluid reporting systems are disclosed. In some embodiments, the system comprises a cart with a base and a load cell. The base can receive and support a cryogenic fluid tank and the weight of the cryogenic fluid tank can be applied to the load cell. The cart can include a transmitter configured to transmit a signal indicative of the weight applied to the load cell. The system can include a receiver configured to receive the signal from the transmitter. The system can include a computing system in communication with the receiver. The computing system can include software configured to correlate the signal indicative of the weight of the cryogenic fluid tank to a fill amount of the tank.

A gas cylinder holder may include a frame that defines a storage region for receiving multiple gas cylinders. The gas cylinders disposed within the storage region may be coupled to an outlet cabinet of the gas cylinder holder that contains components configured to output/deliver gas from the gas cylinders. The gas cylinder holder may further include a control panel configured to control the outlet cabinet components in order to dictate the gas cylinder from which the gas is delivered. The frame of the gas cylinder holder may further include at least one engagement member. A cart or other transportation mechanism may be configured to engage with the at least one engagement member of the frame of the gas cylinder holder to facilitate lifting and moving the gas cylinder cart regardless of whether or not gas cylinders are disposed within the storage region of the gas cylinder holder.

A transport means (N) includes at least one lower support (1) on which at least two cylinders, in which a material which can be a compressed gas is stored, are placed by being stacked on the top of one another; at least one body (3) having one end connected to said lower support (1); at least one first steering element (2a) disposed on the body (3) for steering the cylinders during transport, at least two motion elements (4) connected to said body (3) for providing the movement of the transport means (N), the transport means (N) including at least one thrust mechanism which allows the topmost cylinder to move closer toward the lower support (1) such that the cylinders stacked on the top of one another do not come apart during transport.

A hydrogen filling method for a fuel cell vehicle includes filling a hydrogen tank of the fuel cell vehicle with hydrogen using a hydrogen dispenser by sequentially using a low-pressure storage tank of the fuel cell vehicle, a medium-pressure storage tank of the fuel cell vehicle, and a high-pressure storage tank of the fuel cell vehicle.

A storage tank includes a frame, tank assembly, and scrubber system. The tank assembly including a vessel supported by the frame and having a first end, a second end, and a polygonal sidewall extending from the first end to the second end. The vessel further having a top, a bottom, at least one side, and an internal surface, and an outlet fluidly coupled with the bottom; and a chemical-resistant lining associated with the internal surface of the sidewall and being substantially flexible. A scrubber tank is supported by the frame and fluidly connected to the vessel to receive vapors from the vessel in a way that when a vapor absorption material is disposed in the scrubber tank, the vapors pass into the vapor absorption material.

A gas cylinder cart includes a frame, a first control assembly composed of a first control panel wall and a first gas distribution assembly, a second control assembly composed of a second control panel wall and a second gas distribution assembly, and a central manifold connected to each of the first and second control assemblies. The central manifold includes a valve assembly allowing for connection of both the first and second control assemblies to gas cylinders, connection of only one of the first and second control assemblies to gas cylinders, or connection of the first and/or second control assemblies to remote gas sources. Inclusion of the first and second control assemblies within the gas cylinder cart allows for use of the gas cylinder cart in conjunction with different systems that might require different control assemblies.
