Devices, systems, and methods for detection of medical device

A conduit headgear, comprising:

• an opening configured to removably couple with an air circuit;
• a first portion extending from the opening to a first proximal end, wherein the first proximal end is configured to couple with a patient interface;
• a second portion extending from the opening to a second proximal end, wherein the second proximal end is configured to couple with the patient interface;
• a first stretchable concertina portion extending along a length of the first portion;
• a second stretchable concertina portion extending along a length of the second portion;
• a first antenna located at a region adjacent the opening;
• a second antenna spaced apart from the first antenna;
• and
• a sleeve covering at least one of the first portion or the second portion, wherein the sleeve comprises a conductive electrical connection extending along the sleeve and electrically coupling the first antenna and the second antenna.
