A humidification system can include a heater base, a humidification chamber, and a breathing circuit. A cartridge can be removably coupled to the heater base. The cartridge can include various sensors, probes, sensor wire connectors, heater wire connectors, and/or other features. The cartridge can include features configured to mate with corresponding features on the humidification chamber and the heater base. The cartridge includes a memory, such as an EEPROM, or other suitable storage device. When the cartridge is installed on the heater base, the memory is electrically connected to a processor and/or memory of the heater base. Various models of cartridges can be produced for use with different humidification chambers, breathing circuits, and/or therapies. A connector can be configured to couple an inspiratory conduit to an outlet port of the humidification chamber. The connector can provide a pneumatic connection to the outlet port and an electrical connection to the cartridge.

Connections for humidification system

Tube assembly and connector

Seal

A circuit connector for a humidification system, the system comprising a base unit configured to be engaged by a humidification chamber. The circuit connector comprises an inlet to fluidly connect to an outlet of the humidification chamber to receive humidified gases therefrom, an outlet to sealably connect to or integral with a conduit for directing the humidified gases to a user, and an electrical terminal for electrically coupling the circuit connector to an electrical terminal associated with the base unit. The circuit connector may be releasably and lockably connectable to the outlet of the humidification chamber and/or orientation features may control orientation of component parts of the system as they are assembled.

Humidification system connections

An interface assembly comprises a nasal mask that includes a seal having a rolling portion. The rolling portion of the seal rolls over a portion of a clip that secures the seal to a frame. The frame has a ball and socket connection to a connector. The connector comprises an elbow having integrally formed exhaust holes and a swivel.
