Abstract
A nitric oxide delivery system can include a cassette which is a single use disposable component used to store liquid N2O4, activate upon operator demand, convert N2O4 to NO2 via a heating element(s) controlled by a console to deliver NO2 at a controlled flow rate, direct concentrated NO2 to a contained pair of conversion cartridges and exhaust NO gas to the console for delivery to the patient.
Claims30
A cassette for conversion of nitrogen dioxide to nitric oxide comprising:
- a sealed housing,
- a first cartridge capable of converting nitrogen dioxide gas to nitric oxide within the sealed housing,
- the first cartridge comprising an inlet, a diverter, a body, an outlet, and a porous solid matrix including a reducing agent,
- the porous solid matrix being positioned within the first cartridge such that there is a space between the body of the first cartridge and the porous solid matrix, wherein the porous solid matrix includes an open passage parallel to the length of the body of the first cartridge,
- a second cartridge capable of converting nitrogen dioxide gas to nitric oxide, wherein an outlet of the first cartridge and an inlet of the second cartridge is connected,
- the second cartridge comprising an inlet, a diverter, a body, an outlet, and a porous solid matrix including a reducing agent,
- the porous solid matrix being positioned within the first cartridge such that there is a space between the body of the first cartridge and the porous solid matrix, wherein the porous solid matrix includes an open passage parallel to the length of the body of the first cartridge;
- and
- an inerting chamber including an inerting material.
