Abstract

A patient interface for use in providing a flow of a pressurized treatment gas to an airway of a patient includes a body for receiving the flow of the pressurized treatment gas, a sealing member for engaging with the face of the patient about the airway of the patient, and at least one triboelectric sensor configured to provide a signal indicative of information about one or more of the body and/or the sealing member.

First claim

What is claimed is:

1 . A patient interface for use in providing a flow of a pressurized treatment gas to an airway of a patient, the patient interface comprising:
a body structured to receive the flow of the pressurized treatment gas; a sealing member structured to engage with the face of the patient about the airway of the patient; and at least one triboelectric sensor structured to provide a signal indicative of information about one or more of the body and/or the sealing member.

2 . The patient interface of claim 1 , wherein the at least one triboelectric sensor is structured to provide the signal indicative of information about one or more of the body and/or the sealing member when a portion of the patient interface moves with respect to another portion of the patient interface or with respect to the face of the patient.

3 . The patient interface of claim 1 , wherein the signal is indicative of a type of patient interface or a portion thereof.

4 . The patient interface of claim 1 , wherein the signal is indicative of a size of the patient interface or a portion thereof.

5 . The patient interface of claim 1 , wherein the signal is indicative of a condition of a portion of the patient interface.

6 . The patient interface of claim 1 , further comprising an antenna in communication with the at least one triboelectric sensor.

7 . The patient interface of claim 1 , wherein the at least one triboelectric sensor comprises a plurality of triboelectric sensors.

8 . The patient interface of claim 7 , wherein at least two triboelectric sensors of the plurality of triboelectric sensors are structured to provide a signal indicative of the same information.

9 . The patient interface of claim 7 , wherein at least two triboelectric sensors of the plurality of triboelectric sensors are structured to provide a signal indicative of different information.

10 . A system for providing a flow of a pressurized treatment gas to an airway of a patient, the system comprising:
a pressure generating device structured to produce a flow of a pressurized treatment gas; a patient interface coupled to, and structured to receive the flow of pressurized treatment gas from, the pressure generating device via a conduit, the patient interface comprising:
a body structured to receive the flow of the pressurized treatment gas from the conduit;
a sealing member structured to engage with the face of the patient about the airway of the patient; and
at least one triboelectric sensor structured to provide a signal indicative of information about one or more of the body and/or the sealing member; and
a controller in communication with the at least one triboelectric sensor, the controller structured to receive the signal indicative of information about one or more of the body and/or the sealing member and determine therefrom the information about the one or more of the body and/or the sealing member.

11 . The system of claim 10 , wherein the at least one triboelectric sensor is structured to provide the signal indicative of information about one or more of the body and/or the sealing member when a portion of the patient interface moves with respect to another portion of the patient interface or with respect to the face of the patient.

12 . The system of claim 10 , wherein the signal is indicative of:
a type of patient interface or a portion thereof, a size of the patient interface or a portion thereof, or a condition of a portion of the patient interface.

13 . The system of claim 10 , further comprising an antenna in communication with the at least one triboelectric sensor.

14 . The system of claim 10 , wherein the at least one triboelectric sensor comprises a plurality of triboelectric sensors.

15 . A method of determining information about a patient interface used in providing a flow of pressurized treatment gas to the airway of a patient, the method comprising:
receiving a signal from a triboelectric sensor provided on the patient interface; comparing the signal to a database of known signals; determining information about the patient interface from the comparison; and providing an output based on the information.
