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: 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.

Abstract: A combination wood and metal island leg is disclosed having at least one wood leg element and at least one metal leg element. The wood and metal leg elements are adapted for a vertical coupling to form a combination wood and metal island leg. In one embodiment, a modular leg mount assembly includes a first wood turning, a metal turning, a second wood turning, and a metal foot. The first wood turning, the metal turning, the second wood turning, and the metal foot are adapted for a vertical coupling to form a combination wood and metal leg. In one embodiment, an island table includes a platform and a multiplicity of combination wood and metal island legs mounted to an underside of the platform to provide structural support to the platform and maintain the platform securely at a predetermined height.
