Abstract

The present invention is directed to a nitric gas dispenser for mammals on the run. The dispenser has a housing that contains a valve mechanism. The valve mechanism is interconnected between a nitric gas dispersal component that provides nitric gas at a desired pressure and a gas delivery system that provides the nitric gas at the desired pressure to the mammal. The valve mechanism controls the flow of the nitric gas between the nitric gas dispersal component and the gas delivery system. The dispenser also has a pressure sensor that is positioned along the gas delivery system and determines when the mammal is taking a breadth. If the pressure sensor determines the mammal is taking a breadth, the pressure sensor transmits a breadth signal to a microprocessor. The microprocessor then determines if the mammal is within a prescribed time frame for the mammal to be administered nitric gas. If the microprocessor determine the mammal is within the prescribed time frame, the microprocessor transmits an open signal to the valve mechanism to release a predetermined amount of nitric oxide gas to the mammal.

Claims

1. A nitric gas dispenser for mammals, comprising:

a housing containing a valve mechanism that is interconnected between a nitric gas dispersal component that provides nitric gas at a desired pressure and a gas delivery system that provides the nitric gas at the desired pressure to the mammal;

the valve mechanism controls the flow of the nitric gas between the nitric gas dispersal component and the gas delivery system;

a pressure sensor is positioned along the gas delivery system and determines when the mammal is taking a breadth;

if the pressure sensor determines the mammal is taking a breadth, the pressure sensor transmits a breadth signal to a microprocessor, the microprocessor then determines if the mammal is within a prescribed time frame for the mammal to be administered nitric gas;

if the microprocessor determine the mammal is within the prescribed time frame, the microprocessor transmits an open signal to the valve mechanism to release a predetermined amount of nitric oxide gas to the mammal.

2. The dispenser of claim 1 wherein the nitric gas is transmitted into the nostril of the mammal.

3. The dispenser of claim 1 wherein the prescribed time frame is determined by an operator entering parameters to the microprocessor.

4. The dispenser of claim 3 wherein the housing has a key pad that allows the operator to enter parameter to the microprocessor.

5. The dispenser of claim 3 wherein the parameters are start delay, pulse time, pulse delay, and retrigger lock.
