Portable, nitric oxide generator
First Claim
1. A method of generating nitric oxide, the method comprising:
- providing a mixture of granulated reactants comprising a nitrate compound and a nitrite compound in a reactor;
providing a heating system comprising water in a sealed, breachable container and water-activated chemicals positioned below the mixture of reactants to heat the mixture of reactants;
breaching the container in a manner that activates the water-activated chemicals and produces heat;
heating the mixture of reactants to initiate a reaction within the mixture of reactants, thereby generating nitric oxide gas;
evacuating the nitric oxide gas away from the reactor in a closed conduitdelivering the nitric oxide gas at substantially ambient conditions to a user.

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.

7. A method of providing nitric oxide comprising:
-
selecting a generator comprising a reactor system, self-contained and containing first reactants and second reactants; generating heat by activating the second reactants; generating nitric oxide by activating the first reactants in response to the generating heat; and introducing the nitric oxide into a breathing air of a subject. - View Dependent Claims (8, 9, 10, 11)

12. A method of providing nitric oxide, the method comprising:
-
providing first reactants in a dry mixture, wherein the first reactants are selected to react in response to heating thereof and to generate nitric oxide gas upon heating; providing a first container containing the first reactants, wherein the first container further comprises providing a conduit extending from the first container to conduct the nitric oxide gas from the first container; providing a second container thermally insulated and substantially surrounding the first container and allowing the conduit to pass outside the second container; providing a third container, sealed, breachable, and containing salt water, the third container being located outside the first container and inside the second container; providing second reactants, dry and located inside the second container, the second reactants being selected to react in the presence of water and be exothermic upon reaction in the presence of water, thereby generating energy and heat to initiate reaction of the first reactants in the first container; providing a breaching assembly positioned to breach the third container upon actuation of the breaching assembly and allow the salt water to pour onto the second reactants, initiating mutual reaction of the second reactants; and producing nitric oxide gas. - View Dependent Claims (13, 14, 15, 16)
