Claims for Patent: 8,776,795

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.

Application Number:14/065,975
Patent Claims: 1. A gas delivery device to administer therapy gas from a gas source, the gas delivery device comprising: a valve attachable to the gas source, 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 through the valve; and a circuit including: a memory to store gas data comprising one or more of gas identification, gas expiration date and gas concentration; and a processor and a transceiver in communication with the memory to send and receive signals to communicate the gas data to a control module that controls gas delivery to a subject and to verify one or more of the gas identification, the gas concentration and that the gas is not expired.

2. The device of claim 1, wherein the valve further comprises a data input in communication with said memory, to permit a user to enter the gas data into the memory.

3. The device of claim 1, wherein the signals comprise wireless optical line-of-sight signals.

4. The device of claim 1, further comprising a power source, wherein the transceiver periodically sends the signals to the control module and the signals are interrupted by a duration of time at which no signal is sent to conserve the power source.

5. The device of claim 4, wherein the duration of time at which no signal is sent is in the range from about 5 seconds to about 20 seconds.

6. The device of claim 1, wherein the memory is disposed between the actuator and a cap.

7. A therapy gas delivery system comprising: a gas delivery device comprising: a gas source; a valve attached to the gas source, the valve including an inlet and an outlet in fluid communication and a valve actuator to open or close the valve; and a circuit comprising: a first memory to store gas data comprising one or more of gas identification, gas expiration date and gas concentration of the gas source; and a first processor and a first transceiver in communication with the first memory; and a control module that controls delivery of therapy gas to a subject, the control module comprising a second memory, a second transceiver and a second processor, wherein the second transceiver and the second processor are in communication with the second memory, wherein the first transceiver and the second transceiver send and receive signals to communicate the gas data to the control module and to verify one or more of the gas identification, the gas concentration and that the gas is not expired.

8. The system of claim 7, wherein the control module further comprises a display to enter patient information into the second memory.

9. The system of claim 8, wherein the second processor compares the patient information entered into the second memory via the display and the gas data that the first transceiver communicated to the second transceiver.

10. The system of claim 9, wherein the control module comprises an alarm that is triggered when the patient information entered into the second memory and the gas data from the valve transceiver do not match.

11. The system of claim 7, wherein the second memory comprises instructions that cause the second processor to: receive gas data from the gas delivery device; compare the gas data with patient information; and control delivery of the therapy gas to the patient.

12. The system of claim 11, wherein the second processor verifies one or more of the gas identification, the gas concentration and that the gas is not expired prior to delivery of the therapy gas to the patient.

13. The system of claim 7, wherein the second memory comprises instructions that cause the second processor to: receive a first valve status selected from a first open position and a first closed position from a first valve connected to a first gas source; receive a second valve status selected from a second open position and a second closed position from a second valve connected to a second gas source; 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.

14. The system of claim 7, wherein the signals comprise wireless optical line-of-sight signals.

15. A method for administering a therapy gas to a patient, comprising: establishing communication between a gas delivery device and a control module for administering therapy gas to a subject via a first transceiver and a second transceiver, wherein the gas delivery device comprises a gas source and the first transceiver is in communication with a first memory that stores gas data comprising one or more of gas identification, gas expiration date and gas concentration of the gas source, wherein the control module comprises the second transceiver and a second memory; communicating the gas data from the first transceiver to the second transceiver via wired or wireless signals; comparing the gas data with patient information stored in the second memory to verify the gas data; and controlling delivery of the therapy gas to the patient.

16. The method of claim 15, wherein the signals comprise wireless optical line-of-sight signals.

17. The method of claim 15, further comprising preventing or ceasing delivery of the therapy gas to the patient based on the comparison of the gas data and the patient information.

18. The method of claim 15, further comprising emitting an alert based on the comparison of the drug data and the patient information.

19. The method of claim 15, further comprising entering the drug data into the first memory.

20. The method of claim 15, further comprising entering the patient information into the second memory.
