20220008679 · 2022-01-13 · ·

Various systems and devices for generating nitric oxide are disclosed herein. According to one embodiment, the device includes a body having an inlet, an outlet, and a porous solid matrix positioned with the body. The porous solid matrix is coated with an aqueous solution of an antioxidant, wherein the inlet is configured to receive a gas flow and fluidly communicate the gas flow to the outlet through the solid matrix to convert nitrogen dioxide in the gas flow into nitric oxide. The porous solid matrix allows the device to be used in any orientation. Additionally, the porous solid matrix provides a rigid structure suitable to withstand vibrations and abuse without compromising device functionality.

Electrodes for Nitric Oxide Generation

Systems and methods for nitric oxide (NO) generation systems are provided. In some embodiments, an NO generation system comprises at least one pair of electrodes configured to generate a product gas containing NO from a flow of a reactant gas. The electrodes have elongated surfaces such that a plasma produced is carried by the flow of the reactant gas and glides along the elongated surfaces from a first end towards a second end of the electrode pair. A controller is configured to regulate the amount of NO in the product gas by the at least one pair of electrodes using one or more parameters as an input to the controller. The one or more parameters include information from a plurality of sensors configured to collect information relating to at least one of the reactant gas, the product gas, and a medical gas into which the product gas flows.

Nitrogen dioxide storage device

A nitric oxide delivery system can include a cassette which is a single use disposable component used to store liquid N.sub.2O.sub.4 activate upon operator demand, convert N.sub.2O.sub.4 to NO.sub.2 via a heating element(s) controlled by a console to deliver NO.sub.2 at a controlled flow rate, direct concentrated NO.sub.2 to a contained pair of conversion cartridges and exhaust NO gas to the console for delivery to the patient.

CONVERSION OF NITROGEN DIOXIDE (NO2) TO NITRIC OXIDE (NO)

A nitric oxide delivery system, which includes a gas bottle having nitrogen dioxide in air, converts nitrogen dioxide to nitric oxide and employs a surface-active material, such as silica gel, coated with an aqueous solution of antioxidant, such as ascorbic acid. A nitric oxide delivery system may be used to generate therapeutic gas including nitric oxide for use in delivering the therapeutic gas to a mammal.
