Abstract: 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.

Abstract: The invention relates to a dentition retaining apparatus that includes a joint between a holding member and a supporting member. The holding member is elastically deformable and terminates in an end segment having a length with an outer diameter. The joint includes a coil extending from the supporting member and having an inner diameter that is less than the outer diameter of the end segment of the holding member. The coil is placed around at least a portion of the end segment of the holding member. The coil compresses the end segment of the holding member.
