Summary for Patent: 9,295,802

Title:	Gas delivery device and system
Abstract:	A gas delivery system including a gas delivery device, a control module and a gas delivery mechanism is described. An exemplary gas delivery device includes a valve assembly with a valve and circuit including a memory, a processor and a transceiver in communication with the memory. The memory may include gas data such as gas identification, gas expiration and gas concentration. The transceiver on the circuit of the valve assembly may send wireless optical line-of-sight signals to communicate the gas data to a control module. Exemplary gas delivery mechanisms include a ventilator and a breathing circuit. Methods of administering gas are also described.

Patent Claims:	1. A therapy gas delivery system comprising: a device comprising: a drug source; a first memory to store drug data comprising one or more of drug identification, drug expiration date and drug concentration of the drug source; and a first transceiver in communication with the first memory; and a control module that controls delivery of therapy gas to a subject by delivering therapy gas to a ventilator circuit, the control module comprising a second memory and a second transceiver, wherein the second transceiver is in communication with the second memory, wherein the first transceiver and the second transceiver send and receive signals to communicate the drug data to the control module and to verify one or more of the drug identification, the drug concentration and that the drug is not expired. 2. The system of claim 1, wherein the drug source comprises a gas cylinder. 3. The system of claim 1, wherein the drug source comprises one or more of NO, O.sub.2, NO.sub.2 and CO. 4. The system of claim 1, wherein the control module further comprises an input means to enter patient information into the second memory. 5. The system of claim 4, wherein the control module comprises a processor that compares the patient information entered into the second memory via the input means and the drug data that the first transceiver communicated to the second transceiver. 6. The system of claim 1, wherein the drug data comprises one or more of drug expiration date and drug concentration at the time of filling of the drug source. 7. The system of claim 1, wherein the drug data comprises drug expiration date and drug concentration at the time of filling of the drug source. 8. The system of claim 1, wherein the drug data comprises drug identification, drug expiration date and drug concentration at the time of filling of the drug source. 9. The system of claim 1, wherein the control module comprises a valve and a delivery flow sensor for delivering therapy gas to the ventilator circuit. 10. A method for verifying therapy gas for delivery to a patient, the method comprising: establishing communication between a device and a control module for administering therapy gas to a subject, wherein the device comprises a drug source and a first memory that stores drug data comprising one or more of drug identification, drug expiration date and drug concentration of the drug source, and wherein the control module comprises a second memory; communicating the drug data from the device to the control module via signals; verifying the drug data to verify one or more of the drug identification, the drug concentration and that the drug is not expired; and comparing the drug data with patient information stored in the second memory and emitting an alert based on the comparison of the drug data and the patient information. 11. The method of claim 10, further comprising delivering the therapy gas to the patient. 12. The method of claim 10, further comprising preventing or ceasing delivery of the therapy gas to the patient based on the comparison of the drug data and patient information. 13. The method of claim 10, further comprising entering the drug data into the first memory. 14. The method of claim 10, further comprising entering the patient information into the second memory. 15. The method of claim 10, wherein the drug source comprises one or more of NO, O.sub.2, NO.sub.2 and CO. 16. The method of claim 10, wherein the signals comprise wireless optical line-of-sight signals. 17. The method of claim 10, wherein the drug data comprises one or more of drug expiration date and drug concentration at the time of filling of the drug source. 18. The method of claim 10, wherein the drug data comprises drug expiration date and drug concentration at the time of filling of the drug source. 19. The method of claim 10, wherein the drug data comprises drug identification, drug expiration date and drug concentration at the time of filling of the drug source. 20. The method of claim 10, wherein the control module comprises a valve and a delivery flow sensor for delivering therapy gas to a ventilator circuit.
