Abstract

An adapter for use with a flow generator includes a conduit attachable to the outlet of the flow generator and an identifying element supported by the conduit and providing an identifying feature unique to a specific peripheral component attachable to the flow generator. The identifying feature is communicable to the flow generator so that appropriate operating parameters of the flow generator may be automatically selected by the flow generator to coordinate with the specific peripheral component.

Claims

1. A component of a continuous positive airway pressure (CPAP) system, the CPAP system including a flow generator that is adapted to generate a supply of pressurized breathable gas that is to be provided through an outlet and to a patient that is using the CPAP system for treatment, the component comprising:

a body having an air flow passage adapted to communicate the supply of pressurized breathable gas to the patient via the flow generator; and

an identifying element that is disposed on or in the body and providing an identifying feature that is unique to a specific peripheral component of the CPAP system, the identifying element set to communicate with the flow generator to provide the supply of pressurized gas to the patient via the air flow passage,

wherein the identifying feature is set to be communicated to the flow generator so that at least one appropriate operating parameter out of a plurality of operating parameters of the flow generator may be automatically processed by the flow generator and the supply of pressurized breathable gas is set in accordance with the automatic processing.

2. The component of claim 1, wherein the body is a conduit that is configured to be removably attachable to the outlet of the flow generator,

wherein the identifying element is supported by the conduit.

3. The component according to claim 1, wherein the identifying element is a resistor and the identifying feature is a resistance value.

4. The component according to claim 2, further comprising:

a connector portion supported by the conduit, the identifying element being coupled thereto, where the connector portion is adapted to removably couple with a corresponding connector portion provided on the flow generator.

5. The component according to claim 4, wherein the connector portion and the corresponding connector portion of the flow generator are conductors that are electrically attachable to one another.

6. A CPAP apparatus comprising:

the component according to claim 2;

the flow generator that generates the supply of pressurized breathable gas;

a patient interface that is configured to engage with a face of the patient and provide a seal thereto;

an air delivery conduit coupled between the flow generator and the patient interface to deliver the supply of pressurized air from the flow generator to the patient interface.

7. The CPAP apparatus according to claim 6, wherein the specific peripheral component is the patient interface.

8. The CPAP apparatus according to claim 6, wherein the at least one operating parameter is stored in a memory of the flow generator.

9. The CPAP apparatus according to claim 6, wherein the component is among a plurality of components according to claim 1,

wherein each on one of the plurality of components is associated with a respective peripheral component.

10. The CPAP apparatus according to claim 9, wherein the identifying element of each one of the plurality of components is a resistor and the associated identifying feature is a resistance value, and wherein a total of the resistance values of each one of the plurality of adapters is unique for a given combination of adapters.

11. The component according to claim 1, wherein the body is an adapter that is adapted to attach to the outlet of the flow generator.

12. A method of using the component of claim 1, the method comprising:

operating the flow generator that generates the supply of pressurized breathable gas provided to the patient for treatment;

measuring a parameter of the specific peripheral component;

storing the parameter as the identifying feature;

attaching the specific peripheral component to a flow generator;

communicating the identifying feature from the component to the flow generator; and

operating the flow generating based at least in part on the identifying feature.

13. The method according to claim 12, wherein the specific peripheral component is a patient interface.

14. The method according to claim 12, wherein the stored parameter is a leak parameter that indicates a leak value associated with the specific peripheral component.

15. A CPAP apparatus comprising:

the component according to claim 2;

the flow generator that generates the supply of pressurized air to the patient;

and

the specific peripheral component.

16. The CPAP apparatus of claim 15, wherein the component is incorporated into the specific peripheral component.

17. The CPAP apparatus of claim 16, wherein the component and the specific peripheral component are part of an air delivery conduit.

18. The CPAP apparatus of claim 16, wherein the component and the specific peripheral component are part of a patient interface.

19. The CPAP apparatus of claim 15, wherein the identifying feature is included in a storage medium.

20. The CPAP apparatus of claim 15, wherein the identifying feature is set to be communicated, at least in part, wirelessly to the flow generator.

21. The component of claim 1, further comprising a storage medium that is set to store at least one of the following:

a log of patient use, components used during each use, and/or an end of life service indication.

22. The component of claim 1, wherein the identifying feature includes a leak parameter that indicates a measured leak value associated with the specific peripheral component.

23. The component of claim 22, wherein processing of the at least one appropriate operating parameter compensates for the measured leak value of the specific peripheral component.

24. The component of claim 1, wherein the body is part of the specific peripheral component of the CPAP system.

25. The component of claim 24, wherein the specific peripheral component is an air delivery conduit.
