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.

Claims

1. A method of supplying medical gas to a customer comprising the steps of:

delivering a portable medical gas system, the portable medical gas system including a gas cylinder filled with medical gas, a flow control valve operatively disposed on the cylinder, a cylinder contents gauge within a container, and wherein the flow control valve includes one or more settings adapted to empty the medical gas from the cylinder;

emptying the medical gas from the cylinder;

packing the empty gas cylinder in the container;

verifying the gas cylinder is empty through visual inspection of the cylinder contents gauge or the flow control valve setting;

return shipping the container having an empty cylinder disposed therein from the customer to a designated receiver via commercial carrier; and

delivering a replacement portable medical gas system including a cylinder filled with a medical gas to the customer.

2. The method of claim 1 further comprising the step of providing instructions to the customer for return shipment of the portable medical gas system via commercial carrier, such instructions including advising the customer to ensure the flow control valve is positioned in a setting adapted to empty the medical gas from the gas cylinder.

3. The method of claim 1 further comprising the step of notifying a gas supplier that the portable medical gas system has been used or requires replacement and the step of delivering the replacement portable medical gas system including a cylinder filled with a medical gas to the customer occurs after said step of notification.

4. The method of claim 1 wherein the container comprises one or more transparent surfaces adapted to allow visual inspection of the cylinder contents gauge or the flow control valve setting when the cylinder is placed within the container.

5. The method of claim 1 wherein the flow control valve is a single-use valve wherein upon actuation of the flow control valve, the medical gas within the gas cylinder flows continuously from the gas cylinder until the gas cylinder is empty.

6. The method of claim 1 wherein the flow control valve has a setting for ‘

SHIP’

mode wherein upon placement of the flow control valve in the ‘

SHIP’

mode, the medical gas within the gas cylinder flows continuously from the gas cylinder until the gas cylinder is empty.

7. The method of claim 3 further comprising the step of charging the customer upon delivery of the portable medical gas system, delivery of the replacement portable medical gas system, receipt of the portable medical gas system by the designated receiver, or notification to the gas supplier.

8. A method of supplying medical gas to a customer comprising the steps of:

delivering a portable medical gas system, the portable medical gas system including a cylinder filled with medical gas, a flow control valve operatively disposed on the cylinder, a cylinder contents gauge within a container, and wherein the flow control valve includes a setting adapted to empty the medical gas from the cylinder;

receiving notification from the customer that the portable medical gas system requires replacement;

arranging for return shipment of the portable medical gas system having an empty cylinder via commercial carrier; and

delivering a second portable medical gas system filled to the customer.

9. The method of claim 8 further comprising the step of providing instructions to the customer for return shipment of the portable medical gas system via commercial carrier, such instructions including advising the customer to ensure the flow control valve is positioned in a setting adapted to empty the medical gas from the gas cylinder.

10. The method of claim 8 wherein the step of receiving notification from the customer that the portable medical gas system requires replacement further comprises receiving notification via telephone, email or internet communications.

11. The method of claim 8 wherein the container comprises one or more transparent surfaces adapted to allow visual inspection of the cylinder contents gauge or the flow control valve setting when the cylinder is disposed within the container.

12. The method of claim 8 wherein the flow control valve is a single-use valve wherein upon actuation of the flow control valve, the medical gas within the gas cylinder flows continuously from the gas cylinder until the gas cylinder is empty.

13. The method of claim 8 wherein the flow control valve has a setting for ‘

SHIP’

mode wherein upon placement of the flow control valve in the ‘

SHIP’

mode, the medical gas within the gas cylinder flows continuously from the gas cylinder until the gas cylinder is empty.

14. The method of claim 8 further comprising the step of charging the customer upon delivery of the portable medical gas system, delivery of the second portable medical gas system, or receipt of notification from the customer that the portable medical gas system requires replacement.

15. A method of supplying medical gas to a customer comprising the steps of:

delivering a portable medical gas system, the portable medical gas system including a cylinder filled with medical gas, a flow control valve operatively disposed on the cylinder, a cylinder contents gauge within a shipping container, and wherein the flow control valve includes a setting adapted to empty the medical gas from the cylinder;

providing instructions to the customer for return shipment of the portable medical gas system via commercial carrier, such instructions including advising the customer to ensure the flow control valve is positioned at the setting adapted to empty the medical gas from the cylinder; and

delivering a replacement portable medical gas system including a cylinder filled with a medical gas to the customer upon return shipment of the portable medical gas system or upon notification that the customer requires a replacement portable medical gas system.
