Device and system for heating respiratory conduit

The present invention provides a system for heating a respiratory conduit positioned between a positive airway pressure (PAP) device and a patent interface. The system comprises a first thermistor and a second thermistor encapsulated within the conduit. The first thermistor being mounted in a molding extending inwardly within the conduit proximal to a first end of the conduit which is proximal to the patient interface for measuring temperature proximal to the patient interface. The second thermistor being mounted in a molding extending inwardly within the conduit proximal to a second end of the conduit which is proximal to the PAP device for measuring temperature proximal to the PAP device. The system also includes a heater encapsulated within the conduit including a first wire and a second wire encapsulated within an outer surface of the conduit that generates heat when an electrical current is applied. A third wire and a fourth wire are also encapsulated within the outer surface of the conduit for electrical connection with the first thermistor and/or the second thermistor. The first and second thermistor are electrically isolated from the heater within the conduit.
