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.
- Claim:
1. (canceled)
- Claim:
2. An apparatus comprising a liquid module comprising one or more safety elements and an ampule comprising liquid N2O4; wherein the apparatus forms gaseous NO from the liquid N2O4 for inhalation; and wherein the one or more safety elements prevent environmental exposure to the liquid N2O4.
- Claim:
3. The apparatus of claim 2, wherein the liquid module further comprises one or more heating devices that are in electrical and thermal communication with the ampule.
- Claim:
4. The apparatus of claim 2, wherein the ampule is secured in a two-position component, wherein the two-position component comprises a first of the one or more safety elements present at each position, wherein the ampule is shuttled between the two positions.
- Claim:
5. The apparatus of claim 4, wherein the first of the one or more safety elements present at each position comprises a seal.
- Claim:
6. The apparatus of claim 4, wherein a second of the one or more safety elements comprises an affixing member that secures the ampule to the two-position component.
- Claim:
7. The apparatus of claim 6, wherein the affixing member is a shard containment barrier.
- Claim:
8. The apparatus of claim 4, wherein one of the two positions of the two-positions component is in communication with an inerting chamber.
- Claim:
9. The apparatus of claim 8, wherein a second of the two positions of the two-positions component is an output side configured to deliver the gaseous NO for inhalation.
- Claim:
10. The apparatus of claim 8, wherein the inerting chamber comprises a colored material configured to indicate a breakage of the ampule.
- Claim:
11. The apparatus of claim 2, wherein a third of the one or more safety elements comprise a leak-valve.
- Claim:
12. The apparatus of claim 2, wherein a fourth of the one or more safety elements comprise a seal positioned at an air inflow port of the apparatus and a seal positioned at a NO gas outflow port of the apparatus.
- Claim:
13. The apparatus of claim 2, wherein a fifth of the one or more safety elements comprise a purge material.
- Claim:
14. The apparatus of claim 2, wherein the liquid module is capable of withstanding internal pressure up to 100 psi and a temperature of up to 70° C.
- Claim:
15. The apparatus of claim 2, further comprising a restrictor.
- Claim:
16. The apparatus of claim 2, further comprising a cartridge comprising a porous rigid matrix and an antioxidant, wherein the cartridge is configured to form the gaseous NO.
