Claims for Patent: 8,573,209

Title:Gas delivery device and system
Abstract: A gas delivery system including a gas delivery device (100), a control module (200) and a gas delivery mechanism is described. An exemplary gas delivery device includes a valve (107) assembly with a valve and circuit including a memory (134), a processor (122) and a transceiver (120) 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 (400) and a breathing circuit (410). Methods of administering gas are also described.

Application Number:13/509,873
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 to a control module; and a circuit including: 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 wireless optical line-of-sight signals to communicate the gas data to the control module that controls gas delivery to a subject and to verify one or more of the correct gas, the correct gas concentration and that the gas is not expired, 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.

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

3. 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 to a control module; and a circuit including: 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 wireless optical line-of-sight signals to communicate the gas data to the control module that controls gas delivery to a subject and to verify one or more of the correct gas, the correct gas concentration and that the gas is not expired, wherein the valve comprises a power source; and the 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 device of claim 3, wherein the duration of time at which no signal is sent comprises about 10 seconds.

5. A gas delivery system comprising: 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 to a control module that controls gas delivery to a subject; and a circuit including: 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 wireless optical line-of-sight signals to communicate the gas data to the control module and to verify one or more of the correct gas, the correct gas concentration and that the gas is not expired; and the control module, wherein the control module is in fluid communication with the outlet of the valve and a ventilator and the control module comprises: a CPU transceiver to receive line-of-sight signals from the transceiver; and a central processing unit (CPUC in communication with the CPU transceiver and including a CPU memory, wherein the transceiver communicates the gas data to the CPU transceiver for storage in the CPU memory, and wherein the valve comprises a timer including a calendar timer and an event timer, wherein the 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 transceiver communicates the date and time of opening and closing of the valve to the CPU transceiver for storage in the CPU memory.

6. A gas delivery system comprising: 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 to a control module that control gas delivery to a subject; and a circuit including: 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 wireless optical line-of-sight signals to communicate the gas data to the control module and to verify one or more of the correct gas, the correct gas concentration and that the gas is not expired; and the control module, wherein the control module is in fluid communication with the outlet of the valve and a ventilator and the control module comprises: a CPU transceiver to receive line-of-sight signals from the transceiver; and a central processing unit (CPU) in communication with the CPU transceiver and including a CPU memory, wherein the transceiver communicates the gas data to the CPU transceiver for storage in the CPU memory, wherein the control module further comprises an input means to enter patient information into the CPU memory; and a display, and wherein the CPU compares the patient information entered into the CPU memory via the input means and the gas data from the transceiver.

7. The system of claim 6, wherein the CPU comprises an alarm that is triggered when the patient information entered into the CPU memory and the gas data from the transceiver do not match.
