Abstract

This invention relates to a monitoring, alarm and automatic adjustment system for oxygen and/or compressed air, specifically to warn users of oxygen and/or compressed air of low pressure and/or no supply and automatically adjust the flow of oxygen and/or compressed air to the optimum rate according to the actual real time monitored condition and physiological needs of the user.

Claims

1. A monitoring, alarm and automatic adjustment system for users of oxygen and compressed air comprised of:

a compressed gas storage means;

a pressure regulator means attached to the compressed gas storage means such that the pressure regulator means can regulate the discharge of a gas from the gas storage means;

an electronic control unit attached to the pressure regulator means such that the electronic control unit can activate the pressure regulator means and thereby control the discharge of the gas from the gas storage means;

a user specified length of nasal cannula tubing attached to the pressure regulator means such that the discharge of the gas from the gas storage means can pass through the pressure regulator means into the nasal cannula tubing;

a nasal cannula attached to the nasal cannula tubing such that the gas within the nasal cannula tubing can pass into the nasal cannula and then discharge into the nasal area of the user;

a pressure and temperature sensor attached to the nasal cannula such that the pressure and temperature of the gas as it passes through the nasal cannula may be measured by the pressure and temperature sensor;

a pulse detection means functionally attached to the user;

a blood oxygen concentration detection means functionally attached to the user;

the pressure and temperature sensor, the pulse detection means and the blood oxygen concentration detection means are each functionally connected to the electronic control unit and the electronic control unit is also functionally connected to an electronic control unit pressure and temperature sensor such that the electronic control unit will interpret data it receives by the functional connection from the pressure and temperature sensor, the pulse detection means, the blood oxygen concentration detection means and the electronic control unit pressure and temperature sensor and will automatically adjust the pressure regulator means such that a user selected gas pressure at the nasal cannula will be maintained; and

at least one alarm means functionally attached to the electronic control unit such that if the user selected gas pressure at the nasal cannula is not maintained the electronic control unit will activate the alarm means.

2. The monitoring, alarm and automatic adjustment system for users of oxygen and compressed air of claim 1 wherein the alarm means is at least one vibrator.

3. The monitoring, alarm and automatic adjustment system for users of oxygen and compressed air of claim 1 wherein the alarm means is at least one audible signal producing device.

4. The monitoring, alarm and automatic adjustment system for users of oxygen and compressed air of claim 1 wherein the alarm means is at least one visual signal producing device.

5. The monitoring, alarm and automatic adjustment system for users of oxygen and compressed air of claim 1 wherein the alarm means is comprised of:

at least one vibrator;

at least one audible signal producing device; and

at least one visual signal producing device.

6. The monitoring, alarm and automatic adjustment system for users of oxygen and compressed air of claim 1 wherein the alarm means is attached to a ring.

7. The monitoring, alarm and automatic adjustment system for users of oxygen and compressed air of claim 1 wherein the alarm means is attached to a bracelet.

8. The monitoring, alarm and automatic adjustment system for users of oxygen and compressed air of claim 1 wherein the alarm means is attached to eyeglasses.

9. The monitoring, alarm and automatic adjustment system for users of oxygen and compressed air of claim 1 wherein the alarm means is attached to a necklace.

10. The monitoring, alarm and automatic adjustment system for users of oxygen and compressed air of claim 1 wherein the alarm means is attached to the nasal cannula tubing.

11. The monitoring, alarm and automatic adjustment system for users of oxygen and compressed air of claim 1 wherein the alarm means is attached to the electronic control unit.

12. The monitoring, alarm and automatic adjustment system for users of oxygen and compressed air of claim 1 wherein the pressure and temperature sensor, the pulse detection means, the blood oxygen concentration detection means and the electronic control unit pressure and temperature sensor each are comprised of:

a transmitter wherein the transmitter transmits a signal to a receiver that is functionally attached to the electronic control unit.

13. The monitoring, alarm and automatic adjustment system for users of oxygen and compressed air of claim 1 wherein the alarm means is comprised of:

an alarm receiver wherein the alarm receiver receives a signal from an electronic control unit transmitter.

14. The monitoring, alarm and automatic adjustment system for users of oxygen and compressed air of claim 1 wherein the alarm means are attached to a ring, a bracelet, an anklet, a pair of eyeglasses, a necklace and the electronic control unit.

15. The monitoring, alarm and automatic adjustment system for users of oxygen and compressed air of claim 1 wherein the alarm means is removably attached to the user by Velcro.

16. The monitoring, alarm and automatic adjustment system for users of oxygen and compressed air of claim 1 wherein the alarm means is removably attached to the user by being clipped in a user specified location.
