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 communicatable 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 continuous positive airway pressure (CPAP) system comprising:

a flow generator configured to generate a supply of pressurized breathable gas that is delivered, via an airflow path that includes at least an outlet formed in the flow generator, a delivery conduit, and a patient interface, to a patient for treatment, the flow generator including a first connector structure;

a peripheral CPAP component that is operable to be a component of the CPAP system and assist in application of treatment for the patient;

a connector removably attachable to the first connector structure and separate from the peripheral CPAP component and, when attached, configured to communicate the pressurized breathable gas delivered from the outlet to other components included in the airflow path, the connector including an identifying element disposed on or in the connector with the identifying element including an identifying feature related to the peripheral CPAP component;

an electronic controller electronically coupled to the first connector structure and configured to;

automatically recognize, via the first connector structure, the peripheral CPAP component related to the connector when attached to the first connector structure based on the identifying feature; and

automatically adjust at least one operating parameter of the flow generator based on recognition of the peripheral CPAP component, where adjustment of the operating parameter changes how the supply of pressurized breathable gas is delivered to the patient.

2. The CPAP system of claim 1, wherein the identifying feature includes data of at least one of the following:

a log of patient use, an end of life service indication, components used during each use, and/or a leak parameter that indicates a measured leak value associated with the peripheral CPAP component.

3. The CPAP system of claim 1, wherein the connector has a tactile indicator used to assist in recognizing the peripheral component.

4. The CPAP system of claim 3, wherein the tactile indicator is a polygon or hexagon shape.

5. The CPAP system of claim 1, wherein the identifying feature includes an airflow related parameter of the peripheral CPAP component.

6. The CPAP system of claim 1, wherein the peripheral CPAP component is at least one of the patient interface, the delivery conduit, and a humidifier.

7. The CPAP system of claim 1, where the electronic controller is further configured to:

responsive to recognition of the peripheral CPAP component as a first type of patient interface, set a pressure level of the pressurized breathable gas to a first level; and

responsive to recognition of the peripheral CPAP component as a second type of patient interface, which is different from the first type of patient interface, set the pressure level of the pressurized breathable gas to a second level that is higher than the first level.

8. The CPAP system of claim 1, wherein the connector is configured to structurally couple the first connector structure to an end of the delivery conduit.

9. The CPAP system of claim 1, wherein a diameter of a first end of the connector is greater than a diameter of a second, opposing, end of the connector.

10. The CPAP system of claim 1, wherein the identifying element of the connector is a resistor and the identifying feature is a resistance of a resistor.

11. The CPAP system of claim 10, wherein the peripheral CPAP component is the patient interface and a particular resistance of the resistor is associated with a type of patient interface to which the patient interface belongs.

12. The CPAP system of claim 1, wherein the connector is configured to be electrically coupled to the first connector structure when attached.
