Abstract
A method and an apparatus for plasma-chemical production of nitrogen monoxide is used to produce inhalation gas enriched with nitrogen monoxide for medical purposes. The nitrogen-monoxide production is achieved through the use of a dielectric barrier discharge created in a process gas containing nitrogen and oxygen.
Claims11
An apparatus for plasma-chemical production of nitrogen monoxide for medical purposes, comprising:
- a plasma-chemical reactor for producing dielectric barrier discharges, said reactor including:
- an electrode, with a dielectrically effective layer;
- an opposing electrode;
- mutually facing surfaces of said layer and said opposing electrode forming a discharge gap therebetween for conducting a flow of a process gas containing nitrogen and oxygen in a flow direction;
- a number of constrictions forming discharge zones through which the process gas is passed in said flow direction and within which a dielectric barrier gas discharge is created, said reactor configured to produce said gas discharge having a non-thermal plasma with a gas temperature of at least 400° C.;
- and
- a reactor outlet;
- and
- an interface connected to said reactor outlet to facilitate inhalation of gas, produced from said reactor, by a person.
