Portable, nitric oxide generator
First Claim
1. A method of generating nitric oxide, the method comprising:
- providing a mixture of reactants comprising a nitrate compound and a nitrite compound in a reactor;
providing a heating system comprising water in a sealed, rupturable container and water-activated chemicals positioned below the mixture of reactants to heat the reactor;
rupturing the container in a manner that activates the water-activated chemicals and produces heat;
heating the reactor, thereby generating nitric oxide gas;
delivering the nitric oxide gas at substantially ambient conditions to a user to provide a therapeutically safe concentration of the nitric oxide gas.

Abstract
An apparatus for portable delivery of nitric oxide without the need for pressurized tanks, power supplies, or other devices provides a single therapy session by triggering a heater to heat a reaction chamber. A piercing assembly may trigger to open sealed containers, such as bags, of liquid water or salt water in order to activate the heaters. Upon addition of liquid such as water or salt water to a chemically reactive heating element, heat is generated to activate the chemicals generating nitric oxide within a sealed reactor. Upon triggering, liquid containers are unsealed, the liquid drains down to initiate reaction of the heating chemicals, and the heat begins to penetrate the reactor. The reactor, in turn, heats its contents, which react to form nitric oxide expelled by the reactor to a line feeding a cannula for therapy.
