US Classification:

414810, 414800, 141 1, 141231, 206769

Abstract:

A method of supplying a portable medical gas system is provided. The disclosed method includes preparing a portable medical gas system, the portable medical gas system including a cylinder adapted to be filled with medical gas and a gas dispensing valve. The portable medical gas system is place in a specialized container having a configuration adapted to hold the portable medical gas system only when the cylinder of portable medical gas system is unused state or empty state. The portable medical gas system is delivered to the customer, and returned as an empty cylinder via commercial carrier. Upon receipt of the empty or spent portable medical gas system, another portable medical gas system filled with medical gas is sent to the customer. In one embodiment, the portable medical gas system includes a single-use flow control valve which ensures the cylinder is empty after its initial use.

International Classification:

B67D 5/34

US Classification:

222 3, 239 70

Abstract:

A medical gas cylinder system is provided that includes a gas cylinder, a gas dispensing mechanism for dispensing the medical gas from the gas cylinder, a flow control valve operatively disposed in the dispensing mechanism and adapted to initiate a flow of medical gas from the gas cylinder upon actuation, and a cylinder contents gauge adapted to indicate the status of medical gas within the gas cylinder. The flow control valve includes a setting to ensure the gas contents of cylinder are evacuated prior to return shipment. The disclosed system further includes a shipping container having a configuration adapted to hold the gas cylinder and dispensing mechanism and having one or more transparent surfaces or windows such that the cylinder contents gauge or other cylinder status indication is visible when the gas cylinder and dispensing mechanism are placed in the container. The gas cylinder and container are suitable for shipment via commercial carrier.
