Abstract

A fluid regulation system is provided comprising a source of a fluid, a tube in communication with the source for delivering the fluid from the source to a site, and a valve for controlling the rate of fluid flow from the source to the site. A remote control unit for controlling the valve is also provided to allow the user to adjust the rate of fluid flow from the source through the tube to the site. Typically, the system excludes any means for automatically adjusting the rate of fluid flow from the source through the tube to the site. The invention is particularly useful when the valve is out of the user'"'"'s reach. Also provided is a method for delivering of a fluid to a site.

Claims

1. A fluid regulation system comprising:

a source of a fluid;

a tube in communication with the source for delivering the fluid from the source to a site;

a valve for controlling a rate of fluid flow from the source to the site; and

a remote control unit for controlling the valve to allow a user to adjust the rate of fluid flow from the source through the tube to the site,

wherein the system excludes any means for automatically adjusting the rate of fluid flow from the source through the tube to the site, wherein the remote control unit includes a display for indicating fluid flow rate.

2. The system of claim 1, wherein the fluid is an inert gas.

3. The system of claim 2, wherein the source is a tank comprising the inert gas.

4. The system of claim 2, wherein the inert gas is comprised of argon.

5. The system of claim 2, wherein the inert gas is at a concentration greater than atmospheric concentration.

6. The system of claim 1, wherein the remote control unit is attached to the valve.

7. The system of claim 1, wherein the remote control unit is detached from the valve.

8. The system of claim 6, further comprising a control signal receiver configured to receive an electromagnetic control signal for controlling the valve, wherein the remote control unit is configured to transmit the electromagnetic control signal.

9. The system of claim 8, wherein the receiver is comprised of a translator configured to translate the control signal for controlling the valve.

10. The system of claim 8, wherein the electromagnetic control signal is a radio frequency, microwave, infrared, or visible signal.

11. The system of claim 8, wherein the control signal is digital.

12. The system of claim 8, wherein the signal is analog.

13. The system of claim 8, wherein the remote control unit is further configured to operate using a plurality of control signal frequencies.

14. The system of claim 13, wherein the remote control unit is further configured to operate with frequency hopping capability.

15. The system of claim 1, wherein the remote control unit is a handheld unit.

16. The system of claim 15, wherein the remote control unit is configured to provide fingertip adjustment of the rate of fluid flow.

17. The system of claim 1, wherein the remote control unit is sound activated unit.

18. The system of claim 17, wherein the remote control unit is further configured to provide voice recognition adjustment of the rate of fluid flow.

19. The system of claim 1, wherein the display is a digital display.

20. The system of claim 1, wherein the display is an analog display.

21. The system of claim 1, wherein the remote control unit is configured for controlling the valve to a range of about 50 feet.

22. The system of claim 1, wherein the remote control unit is configured to control the valve to a range of about 120 feet.

23. The system of claim 22, wherein the remote control unit is configured to control the valve to a range of about 300 feet.

24. The system of claim 1, wherein the remote control unit is configured to control the valve to a range equal to or greater than a length of the tube.

25. The system of claim 1, wherein the valve comprises a motor.

26. The system of claim 1, wherein the valve provides a substantially constant flow rate of the fluid to the site.

27. The system of claim 1, further comprising an explosion-proof container comprising the valve.

28. The system of claim 1, further comprising an electrical connection with a source of alternating electrical current configured to power the valve.

29. The system of claim 28, further comprising a backup battery configured to power the valve when the source of alternating electrical current is inoperative.

30. The system of claim 28, wherein the valve is manually operative when the source of alternating electrical current is inoperative.

31. The system of claim 1, further comprising a leak detector configured to detect a leak associated with the valve.

32. The system of claim 1, further comprising an additional remote control unit configured to control the valve.

33. The system of claim 32, wherein the control unit is configured to override any signal from the additional control unit for controlling the valve.

34. The system of claim 1, further comprising a fluid flow sensor configured to detect and monitor the rate of fluid flow to the site.

35. The system of claim 34, wherein the fluid flow sensor represents a component of an error detection system.

36. The system of claim 34, further comprising an indicator configured to indicate the rate of fluid flow detected and monitored by the fluid flow sensor.

37. The system of claim 36, wherein the indicator is located in the remote control unit.

38. The system of claim 36, wherein the indicator is located in a monitoring station.

39. The system of claim 38, wherein the monitoring station is a workstation configured to control a plurality of valves and is equipped with an indicator for each valve controlled thereby.

40. A fluid regulation system for delivering fluid from a source containing a fluid to a site, comprising:

a valve comprised of

an inlet configured to receive fluid from the source, an outlet configured to deliver the fluid to the site,

a means for altering fluid flow from the inlet to the outlet, and

a receiver for receiving a signal for controlling the means for altering the fluid flow; and

a remote control unit for transmitting the signal for controlling the means for altering the fluid flow,

wherein the remote control unit allows a user to control a rate of the fluid flow to the site, and the system excludes any means for automatically adjusting the rate of the fluid flow from the source through the tube to the site,

wherein the remote control unit includes a display for indicating fluid flow rate.
