Abstract
A nitric oxide generator generates nitric oxide from a mixture of nitrogen and oxygen such as air treated by a pulsating electrical discharge. The desired concentration of nitric oxide is obtained by controlling at least one of a frequency of the pulsating electrical discharge and duration of each electrical discharge pulse.
Claims32
An apparatus for generating nitric oxide comprising:
- (i) a reaction chamber;
- (ii) an inlet to provide a flow of reactant gas comprising nitrogen and oxygen to the reaction chamber;
- (iii) a pair of electrodes located in the reaction chamber and separated by a gap;
- (iv) a flow meter for measuring a gas flow from an external regulated source to determine the flow of the reactant gas through the reaction chamber;
- (v) an electronic control circuit in communication with the flow meter and the electrodes to generate an electric arc discharge across the gap, wherein the electronic control circuit is configured to control a pulse frequency of the electric arc discharge and a pulse duration of the electric arc discharge independent of the pulse frequency;
- and wherein the electric arc discharge across the gap determines a concentration of nitric oxide generated in the reactant gas to produce a product gas comprising nitric oxide;
- and
- (vi) an outlet for the product gas comprising nitric oxide.

- wherein the pulse frequency of the electric arc discharge is within a range of 0.1 and 100 Hz, and the pulse duration of the electric arc discharge is within a range of 20 microseconds and 500 milliseconds, and wherein the electric arc discharge across the gap determines a concentration of nitric oxide generated in the reactant gas to produce a product gas comprising nitric oxide;
- (vi) one or more additional sensors;
- (vii) one or more filters;
- and
- (viii) an outlet to provide the product gas comprising nitric oxide;
- wherein the outlet is in communication with a nitric oxide applicator to deliver the product gas to a patient.
