Gas delivery device and system

1. A valve assembly to deliver a gas comprising NO from a gas container containing the gas comprising NO, the valve assembly comprising:

a valve attachable to the gas container containing the gas comprising NO, the valve including an inlet and an outlet in fluid communication and a valve actuator to open or close the valve to allow the gas comprising NO through the valve to a control module;

a circuit supported within the valve assembly and disposed between the actuator and a cap, the circuit including:

a valve memory to store gas data comprising gas concentration in the gas container and

a valve processor and a valve transceiver in communication with the valve memory to send wireless optical line-of-sight signals to communicate the gas data to the control module that controls gas delivery to a subject; and

a data input disposed on the actuator and in communication with said valve memory, to permit a user to enter the gas data into the valve memory.

2. The valve assembly of claim 1 , wherein the gas data is provided in a bar code disposed on the gas container and is entered into the data input by a user-operated scanning device in communication with the data input.

3. The valve assembly of claim 1 , wherein the valve comprises a power source; and the valve transceiver periodically sends the wireless optical line-of-sight signals to the control module, wherein the signals are interrupted by a duration of time at which no signal is sent.

4. The valve assembly of claim 3 , wherein the duration of time at which no signal is sent comprises about 10 seconds.

5. A gas delivery system comprising:

the valve assembly of claim 1 ;

wherein the control module is in fluid communication with the outlet of the valve, the control module comprising:

a CPU transceiver to receive line-of-sight signals from the valve transceiver;

a CPU in communication with the CPU transceiver and including a CPU memory; and

a display to enter patient information into the CPU memory,

wherein the valve transceiver communicates the gas data comprising gas concentration to the CPU transceiver for storage in the CPU memory, and wherein the CPU compares the patient information entered into the CPU memory via the display and the gas concentration from the valve transceiver.

6. The system of claim 5 , wherein the valve comprises a timer including a calendar timer and an event timer, wherein the valve memory stores the date and time of opening and closing of the valve and the duration of time that the valve is open and the valve transceiver communicates the date and time of opening and closing of the valve to the CPU transceiver for storage in the CPU memory.

7. The system of claim 5 , wherein the CPU comprises an alarm that is triggered when the patient information entered into the CPU memory and the gas data from the valve transceiver do not match.

8. The system of claim 5 , wherein the CPU memory comprises instructions that cause the CPU processor to: receive gas data comprising gas concentration from the valve via a wireless optical line-of-sight signal with the valve connected to the gas container containing gas comprising NO; compare the gas data with user-inputted patient information; coordinate delivery of therapy to the patient with a medical device via the wireless optical line-of-sight signal between the CPU transceiver and the valve transceiver; select a therapy for delivery to a patient based on the received patient information; and control delivery of the selected therapy to the patient.

9. The system of claim 8 , wherein the memory further comprises instructions that cause the CPU processor to:

receive a first valve status selected from a first open position and a first closed position from a first valve via a first wireless optical line-of-sight signal with the first valve connected to a first gas container;

receive a second valve status selected from a second open position and a second closed position from a second valve via a second wireless optical line-of-sight signal with the second valve connected to a second gas container;

compare the first valve status and the second valve status; and

emit an alarm if the first valve status comprises the first open position and the second valve status comprises the second open position.

10. The system of claim 9 , wherein the memory further comprises instructions that causes the CPU processor to:

terminate delivery of therapy if the first valve status comprises the first open position and the second valve status comprises the second open position.

11. A method for administering a therapy gas comprising NO to a patient, the method comprising:

establishing communication via a CPU transceiver with the valve assembly of claim 1 and communicating the gas data from the valve transceiver to the CPU transceiver,

comparing the gas data communicated from the valve transceiver with patient information stored within a CPU memory;

coordinating delivery of therapy to a patient with the gas delivery device via a wireless optical line-of-sight signal between the CPU transceiver and the valve transceiver;

selecting a therapy for delivery to the patient based on the comparison of the gas data and the patient information; and

controlling delivery of the selected therapy to the patient.

12. The method of claim 11 , further comprising ceasing delivery of the selected therapy to the patient based on the comparison of the gas data and the patient information.

13. The method of claim 11 , further comprising emitting an alert based on the comparison of the gas data and the patient information.

14. The method of claim 11 , further comprising entering the gas data into the valve memory.

15. The method of claim 11 , further comprising entering the patient information into the CPU memory.

16. A gas delivery device comprising:

the valve assembly of claim 1 ; and

the gas container containing gas comprising NO attached to the valve assembly, wherein a bar code disposed on the gas container provides the gas data.
