Devices, systems, and methods for detection of medical device

An air adapter tube for diagnosis and/or treatment of a respiratory disorder, comprising:

• a tubular body, wherein a length of the tubular body is between about 8.5-10 cm;
• a proximal end and a distal end, wherein the proximal end is configured to removably couple to a patient interface, and the distal end is configured to removably couple to an air delivery tube;
• a sensor configured to generate a signal based a sensed physical quantity;
• and
• an antenna configured to receive data from an RFID tag.

An air adapter tube for diagnosis and/or treatment of a respiratory disorder, comprising:

• a tubular body configured to transport pressurized treatment air between a proximal end of the tubular body and a distal end of the tubular body, the proximal end being configured to connect to a patient interface, and the distal end being configured for connection to an air delivery tube;
• a flexible printed circuit at the proximal end which includes linear sections to support electronic components and at least one flexible bent portion between the linear sections;
• and
• a plurality of sensors being configured to generate a signal based on air flow at the proximal end for diagnosis and/or treatment of a respiratory disorder, wherein one of the plurality of sensors is a pressure sensor, and another of the plurality of sensors is an accelerometer.
