Abstract

A method of operating a medical system, including coupling a medical system to an outlet of a fluid distribution network having a plurality of fluid outlets in a patient treatment center; delivering fluid from the outlet to the medical system; compressing the delivered fluid with the medical system; decreasing the moisture content of the delivered fluid with the medical system; cooling the fluid with the medical system; delivering the fluid from the medical system to a medical device; and removing the fluid from medical device with the medical system.

Claims (26)

1. A medical fluid conditioning system for use in association with a fluid delivery subsystem and a fluid distribution network, the fluid distribution network having a plurality of fluid outlets in communication with a central fluid supply and the fluid delivery subsystem including a conditioned fluid reservoir and being in communication with a medical device, the medical fluid conditioning system comprising:

a fluid delivery conduit defining an inlet engageable with one of the fluid outlets of the fluid distribution network and an outlet engageable with the medical device;

a compressor in fluid communication with the fluid delivery conduit;

an adsorbent element disposed in the fluid delivery conduit; and

a subcooler in thermal communication with the fluid delivery conduit,

the medical fluid conditioning system being upstream of the conditioned fluid reservoir of the fluid delivery subsystem and downstream of the fluid distribution network.

2. The medical fluid conditioning system of claim 1 , wherein the fluid delivery subsystem comprises a medical device coupled to the outlet of the fluid delivery conduit.

3. The medical fluid conditioning system of claim 2 , wherein the medical device is a cryogenic treatment device.

4. The medical fluid conditioning system of claim 1 , wherein the compressor operates to compress a fluid received from the fluid outlet to a pressure between approximately 500 psig to 1,000 psig.

5. The medical fluid conditioning system of claim 1 , wherein the adsorbent element reduces a humidity level of a fluid received from the fluid outlet to approximately 60 ppm or less.

6. The medical fluid conditioning system of claim 1 , wherein the fluid delivery subsystem further comprises a fluid return conduit engageable with the medical device.

7. The medical fluid conditioning system of claim 6 , wherein the fluid delivery subsystem further comprises a vacuum pump coupled to the fluid return conduit.

8. The medical fluid conditioning system of claim 1 , wherein the fluid delivery subsystem further comprises a flow meter coupled to the fluid delivery conduit.

9. The medical fluid conditioning system of claim 1 , wherein the fluid distribution network is integral within a patient treatment center.

10. The medical fluid conditioning system of claim 1 , wherein the fluid distribution network provides nitrous oxide.

11. A method of operating a medical fluid conditioning system, comprising:

coupling a medical fluid conditioning system to an outlet of a fluid distribution network having a plurality of fluid outlets in a patient treatment center;

coupling the medical fluid conditioning system to a fluid delivery subsystem, the fluid delivery subsystem being in fluid communication with a medical device;

delivering fluid from the outlet of the fluid distribution network to the medical fluid conditioning system;

compressing the delivered fluid with the medical fluid conditioning system;

decreasing the moisture content of the delivered fluid with the medical system to approximately 60 ppm or less with the medical fluid conditioning system;

cooling the fluid with the medical fluid conditioning system;

delivering the fluid from the medical fluid conditioning system to the fluid delivery subsystem;

delivering the fluid from the fluid delivery subsystem to the medical device; and

removing the fluid from medical device with the fluid delivery subsystem.

12. The method of claim 11 , wherein the fluid is compressed to a pressure between approximately 500 psig to 1,000 psig.
