Abstract
Various systems, devices, NO2 absorbents, NO2 scavengers and NO2 recuperator for generating nitric oxide are disclosed herein. According to one embodiment, an apparatus for converting nitrogen dioxide to nitric oxide can include a receptacle including an inlet, an outlet, a surface-active material coated with an aqueous solution of ascorbic acid and an absorbent wherein the inlet is configured to receive a gas flow and fluidly communicate the gas flow to the outlet through the surface-active material and the absorbent such that nitrogen dioxide in the gas flow is converted to nitric oxide.
Claims13
A system for delivering nitric oxide to a patient, comprising:
- an apparatus;
- a gas source comprising nitrogen dioxide that is delivered to the apparatus, wherein the apparatus converts the nitrogen dioxide to a gas comprising nitric oxide that is delivered to the patient;
- and
- at least one safety device comprising a filter, wherein the filter is a particle and/or bacteria filter having a disk or tubular shape, wherein the filter is positioned in a flow path between the apparatus and the patient, and wherein
- the at least one safety device is further configured to reduce an amount of the nitrogen dioxide in the gas comprising nitric oxide before it is delivered to the patient in an amount below 0.1 ppm.
