Abstract

A system is provided for regulating a flow of oxygen to a patient where the system may include an oximeter for measuring the patient'"'"'s blood oxygen level and/or heart rate; a controller for determining a desired oxygen flow rate based on the patient'"'"'s blood oxygen level and/or heart rate, and generating a control signal representative of the desired oxygen flow rate; an oxygen flow regulator for dynamically regulating a flow rate of oxygen supplied to the patient responsive to the control signal provided by the controller; an oxygen delivery device; and a transmitter for wirelessly communicating with an electronic medical records system. The oxygen flow regulator may receive oxygen from an oxygen bottle, oxygen mixer, a wall oxygen supply of a healthcare facility, or an oxygen concentrator. One or more of the components of the system may be treated with an antimicrobial material.

Claims

1. A system for regulating a flow of oxygen to a patient comprising:

an oximeter for measuring at least one of the patient'"'"'s blood oxygen level and heart rate;

a controller for acquiring the patient'"'"'s blood oxygen level/heart rate from said oximeter, determining a desired oxygen flow rate based on the patient'"'"'s blood oxygen level/heart rate, and generating a control signal representative of the desired oxygen flow rate; and

an oxygen flow regulator for dynamically regulating a flow rate of oxygen supplied to the patient responsive to the control signal provided by said controller.

2. The oxygen flow regulating system of claim 1, wherein said oxygen flow regulator is configured for regulating the flow rate of oxygen received from an oxygen bottle.

3. The oxygen flow regulating system of claim 1, wherein said oxygen flow regulator is configured for regulating the flow rate of oxygen received from a wall oxygen supply of a healthcare facility.

4. The oxygen flow regulating system of claim 1, wherein said oxygen flow regulator is configured for regulating the flow rate of oxygen received from an oxygen concentrator.

5. The oxygen flow regulating system of claim 1, wherein said oximeter is a pulse oximeter.

6. The oxygen flow regulating system of claim 1, wherein said oximeter communicates wirelessly with said controller.

7. The oxygen flow regulating system of claim 1, wherein said controller includes a transmitter for wirelessly communicating with an electronic medical records system, wherein said transmitter transmits at least one of the patient'"'"'s blood oxygen level and the oxygen flow rate to the electronic medical records system.

8. The oxygen flow regulating system of claim 1 and further comprising an oxygen delivery device comprising one of a nasal cannula and a mask.

9. The oxygen flow regulating system of claim 8, wherein at least one of said oximeter, said oxygen flow regulator, and said oxygen delivery device is treated with an antimicrobial material.

10. The oxygen flow regulating system of claim 8, wherein said oxygen delivery device comprises a nasal cannula having an oxygen delivery hose, and wherein said oximeter is configured to secure to the patient'"'"'s septum and is integrated with said oxygen delivery hose.

11. An integrated oximeter and oxygen delivery device comprising:

a nasal cannula having an oxygen delivery hose for delivering oxygen to a patient'"'"'s nose; and

an oximeter integrated with said oxygen delivery hose for securing to the patient'"'"'s septum to read the patient'"'"'s blood oxygen level.

12. The integrated oximeter and oxygen delivery device of claim 11 further comprising a wire for connecting to said oximeter, said wire being secured to said oxygen delivery hose.

13. The integrated oximeter and oxygen delivery device of claim 11 further comprising a second oxygen delivery hose integrated with said oximeter.

14. A method for regulating a flow of oxygen to a patient comprising:

continuously measuring at least one of a patient'"'"'s blood oxygen level and heart rate;

automatically determining a desired oxygen flow rate based on the measured blood oxygen level/heart rate; and

dynamically regulating a flow rate of oxygen supplied to the patient responsive to the determined desired oxygen flow rate.

15. The method of claim 14 and further comprising providing an oxygen bottle, wherein the step of dynamically regulating a flow rate of oxygen regulates the flow rate of oxygen received from the oxygen bottle.

16. The method of claim 14, wherein the step of dynamically regulating a flow rate of oxygen regulates the flow rate of oxygen received from a wall oxygen supply of a healthcare facility.

17. The method of claim 14, wherein the step of dynamically regulating a flow rate of oxygen regulates the flow rate of oxygen received from an oxygen concentrator.

18. The method of claim 14, wherein the oximeter is a pulse oximeter.

19. The method of claim 14, wherein the oximeter communicates wirelessly.

20. The method of claim 14 and further comprising wirelessly transmitting at least one of the patient'"'"'s blood oxygen level and the oxygen flow rate to an electronic medical records system.
