Device for administration of nitric oxide to horses spontaneously breathing

1. A nitric oxide gas dispenser for mammals, comprising:

a housing containing a valve mechanism that is interconnected between a nitric oxide gas dispersal component that provides nitric oxide gas at a desired pressure and a gas delivery system transmits the nitric gas directly into, without premixing with other gases, and at the desired pressure to the mammal;

the valve mechanism controls the flow of the nitric oxide gas between the nitric oxide 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 breath;

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

if the microprocessor determine the mammal is within the proscribed time frame, the microprocessor transmits an open signal to the valve mechanism to release a predetermined amount of nitric oxide gas directly, without pre-mixing with other gases, into the mammal.

2. The dispenser of claim 1 wherein the nitric oxide 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.
