Systems And Methods For Indicating Lifetime Of An NO2-to-NO Reactor Cartridge Used To Deliver NO For Inhalation Therapy To A Patient

摘要

The principles and embodiments of the present invention relate to methods and systems for safely providing NO to a recipient for inhalation therapy. There are many potential safety issues that may arise from using a reactor cartridge that converts NO2 to NO, including exhaustion of consumable reactants of the cartridge reactor. Accordingly, various embodiments of the present invention provide systems and methods of determining the remaining useful life of a NO2-to-NO reactor cartridge and/or a break-through of NO2, and providing an indication of the remaining useful life and/or break-through.

主权项

1. A system for safely delivering a supply of NO to a recipient, comprising:
a gas source that supplies a gas; a gas conduit connected to and in fluid communication with the gas source; a NO2-to-NO reactor cartridge connected to and in fluid communication with the gas conduit, so as to allow gas to flow from the gas source to an inlet end of the NO2-to-NO reactor cartridge; a means of monitoring the functioning of the NO2-to-NO reactor cartridge operatively associated with the NO2-to-NO reactor cartridge; a delivery conduit connected to and in fluid communication with an outlet end of the NO2-to-NO reactor cartridge that allows NO gas from the NO2-to-NO reactor cartridge to flow to a recipient; a computer in electronic communication with the monitoring means over a communication path, wherein the computer is configured to receive electronic signals from the monitoring means and calculate a performance value; and a regulating means in electronic communication with the computer over a communication path.
