Gas regulator with integrated sensors
A gas regulator is described. The gas regulator includes a gas inlet having an attachment mechanism for attaching to a gas container, a gas outlet in fluid communication with the gas inlet and further in fluid communication with a gas delivery system, a pressure regulator, a pressure sensor and a NFC sensor. A method of entering at least one information item relating to a gas source to a gas delivery system control unit. The method includes the steps of providing a gas source having a NFC tag that includes at least one information item stored in a memory of the NFC tag, attaching a regulator that includes a NFC sensor, wherein the NFC sensor is positioned to read the NFC tag when attached to the gas source, reading the at least one information item via the NFC sensor, and transmitting the at least one information item read by the NFC sensor to a gas delivery system control unit.
1. A gas regulator, comprising:
a housing;
a gas inlet to the housing, the gas inlet having an attachment mechanism configured to attach to a valve assembly of a pressurized gas container holding a gas at a raised pressure;
a gas outlet from the housing, the gas outlet in fluid communication with the gas inlet and configured for fluid communication with a gas delivery system;
a pressure regulator within the housing; and
a Near Field Communication (NFC) sensor within the housing configured for communication with the gas delivery system and configured to sense an NFC tag on the pressurized gas container when the NFC sensor is positioned within 10 cm of the NFC tag.
2. The regulator of claim 1 , further comprising a pressure sensor within the housing.
3. The regulator of claim 1 , wherein the NFC sensor comprises a NFC reader.
4. The regulator of claim 1 , wherein the regulator is configured for communicative connectivity to a gas delivery system control unit.
5. The regulator of claim 4 , wherein the regulator is configured to transmit data read from the NFC tag to the gas delivery system control unit.
6. The regulator of claim 5 , wherein the data read from the NFC tag is selected from the group consisting of gas type, gas concentration, gas volume, gas expiration date, gas container owner, gas container size, and gas tank inspection dates.
7. The regulator of claim 4 , wherein the regulator is configured to transmit a signal indicative of sensed pressure by the pressure sensor to the gas delivery control unit.
8. The regulator of claim 6 , wherein the pressure regulator is controlled by the control unit.
9. The regulator of claim 7 , wherein the pressure regulator is controlled by the control unit.
10. The regulator of claim 1 , further comprising a pressure gauge.
11. The regulator of claim 1 , wherein the pressurized gas container comprises a therapeutic gas.
12. A method of entering at least one information item relating to a pressurized gas source to a gas delivery system control unit, comprising the steps of:
providing a pressurized gas source holding a gas at a raised pressure, the pressurized gas source having a NFC tag that includes at least one information item stored in a memory of the NFC tag;
attaching the regulator of claim 1 to the pressurized gas source, wherein the NFC sensor of the regulator is positioned to read the NFC tag when attached to the pressurized gas source;
reading the at least one information item via the NFC sensor; and
transmitting the at least one information item read by the NFC sensor to a gas delivery system control unit.
13. The method of claim 12 , wherein the at least one information item is selected from the group consisting of gas type, gas concentration, gas volume, gas expiration date, gas container owner, gas container size, and gas tank inspection dates.
14. The method of claim 12 , further comprising sensing the pressure of gas from the pressurized gas source via a pressure sensor positioned in the regulator, and transmitting a signal indicative of the sensed pressure to the gas delivery system control unit.
15. The method of claim 12 , wherein the pressurized gas source comprises a therapeutic gas.
16. A method of controlling flow of a pressurized therapeutic gas to a gas delivery system, comprising the steps of:
providing a pressurized gas source having a gas at a raised pressure, the pressurized gas source having a NFC tag that includes at least one information item stored in a memory of the NFC tag;
attaching a regulator that includes a NFC sensor within a housing, wherein the housing of the regulator includes a gas inlet and outlet and is in fluid communication with a gas delivery system, and wherein the NFC sensor within the regular housing is positioned to read the NFC tag when the regulator is attached to the pressurized gas source and within 10 cm of the NFC tag;
reading the at least one information item via the NFC sensor;
transmitting the at least one information item read by the NFC sensor to a gas delivery system control unit; and
controlling the flow of pressurized gas based on the transmitted at least one information item.
17. The method of claim 16 , wherein the at least one information item is selected from the group consisting of gas type, gas concentration, gas volume, gas expiration date, gas container owner, gas container size, and gas tank inspection dates.
18. The method of claim 16 , further comprising sensing the pressure of gas from the pressurized gas source via a pressure sensor positioned in the regulator, and transmitting a signal indicative of the sensed pressure to the gas delivery system control unit.
