Abstract

A apparatus for delivering oxygen to a patient is provided. The apparatus includes a gas source such as an oxygen concentrator and a portable intelligent controller that is movable relative to the gas source and operable over a distance from the gas source. The portable intelligent controller is compact, lightweight and configured to remotely monitor and control one or more functions of the gas source. The functions include compressor speed, product gas production rate, valve timing, power supply and the like. The portable intelligent controller also has a user interface which allows the user to remotely adjust one or more settings of the gas source. In some implementations, the portable intelligent controller also includes a satellite conserver, which delivers oxygen in metered amounts in response to sensed breaths of the patient.

Claims

1. An apparatus for delivering oxygen to a patient, comprising:

an oxygen concentrator having an oxygen delivery outlet;

a flexible tube having a length, one end of said tube connected to receive oxygen from said outlet;

a conserver which delivers oxygen in metered amounts in response to sensed breaths of the patient, said conserver being connected to (i) receive oxygen from the other end of the tube and (ii) deliver the oxygen to the patient; and

a controller which controls one or more functions of the oxygen concentrator, the controller being movable relative to the oxygen concentrator and operable over a distance from the oxygen concentrator, said distance is substantially equal to or greater than the length of the flexible tube.

2. The apparatus of claim 1, wherein the controller comprises a user interface, said user interface is configured for the patient to remotely adjust one or more settings of the oxygen concentrator.

3. The apparatus of claim 1, wherein the controller controls one or more functions of the conserver.

4. The apparatus of claim 3, wherein the controller controls the timing of one or more conserver valves.

5. The apparatus of claim 1, wherein the controller controls one or more functions of the oxygen concentrator, said functions are selected from the group consisting of compressor speed, valve timing, flow rate, gas production rate, supply voltage or current, and combinations thereof.

6. The apparatus of claim 1, wherein the controller communicates with the oxygen concentrator by a communication interface selected from the group consisting of electronic cable, wireless electronic communication, infrared communication, radio control communication and combinations thereof.

7. The apparatus of claim 6, wherein said communication interface between the controller and the concentrator is external to the concentrator.

8. The apparatus of claim 1, wherein the controller is in communication with external respiratory care diagnostic tools.

9. The apparatus of claim 8, wherein the respiratory care diagnostic tools are selected from the group consisting of oximeters, spirometers, and combinations thereof.

10. The apparatus of claim 1, wherein the flexible tube has a length of at least 10 feet.

11. A method of producing a therapeutic gas, comprising:

providing an oxygen concentrator having a plurality of settings which control the function of said concentrator; and

adjusting the function of the concentrator by generating a signal at a distance from the concentrator wherein said signal being generated by a programmable controller, propagating the signal over said distance, using the concentrator to sense said signal, and altering one or more of said settings in response to sensing of said signal by the concentrator.

12. The method of claim 11, wherein adjusting the function of the concentrator comprises adjusting a concentrator operating parameter selected from the group consisting of compressor speed, valve timing, flow rate, gas production rate, supply voltage or current, and combinations thereof.

13. The method of claim 12, wherein propagating said signal comprises propagating an electric signal using a method selected from the group consisting of electronic cable interface, wireless communication, and combinations thereof.

14. An apparatus for delivering therapeutic gas to a patient, comprising:

a therapeutic gas source having a therapeutic gas delivery outlet;

a portable intelligent controller;

a communication interface between said gas source and controller;
