Abstract: A patient interface is disclosed, comprising a chassis portion having a pair of laterally projecting connection portions configured to connect to gas delivery tubes, a seal-forming structure and a vent. The seal forming structure may comprise a central portion configured to seal in use against an inferior periphery of the patient's nose and a pair of lateral posterior regions. Each lateral posterior region may comprise a decoupling portion configured to at least partially decouple the central portion from a respective one of the laterally projecting connection portions. The seal-forming structure may comprise rigidising portions, a central anterior portion having a superior portion stiffer than an inferior portion, mid-lateral anterior portions having superior portions stiffer than inferior portions, and/or a lip superior portion having an anterior portion stiffer than a posterior portion. The chassis portion may be formed from a flexible material and may comprise chassis superior reinforcing portions.

Abstract: A dew point sensor system contains a controller (22) with a dew point calculator, an ambient temperature sensor (20), an air pathway (52), a heater plate (32), and an external wire (60). The ambient temperature sensor (20) generates ambient temperature data, and the ambient temperature sensor (20) is operatively-connected to the controller (22). The air pathway (52) contains a blower (38) within the air pathway (52), an air flow sensor (26) within the air pathway (52), a liquid reservoir (56) operatively-connected to the air pathway (52), and component which may be an air pathway temperature sensor (28) and/or a breathing circuit heating element. The blower (38) causes air to move in the air pathway (52), while the air flow sensor (26) generates air flow data about the air moving in the air pathway (52). The heater plate (26) contains a heater plate temperature sensor (34), and the heater plate temperature sensor (34) generates heater plate temperature data. An external wire (60) is operatively-connected to the controller (22) and the component. The ambient temperature sensor (20) is located on the external wire (60). The heater plate (26), and the heater plate temperature sensor (34) are operatively-connected to the controller (22), and the controller (22) receives the ambient temperature data, the air flow data, and the heater plate temperature data to calculate the target heater plate temperature, based on the dew point temperature. A method of modulating a humidifier heater plate, a humidifier, and a medical device may also include the dew point sensor system.
