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 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 disclosure relates to medical tubes and methods of manufacturing medical tubes. The tube may be a composite structure made of two or more distinct components that are spirally wound to form an elongate tube. For example, one of the components may be a spirally wound elongate hollow body, and the other component may be an elongate structural component also spirally wound between turns of the spirally wound hollow body The tube need not be made from distinct components, however. For instance, an elongate hollow body formed (e.g., extruded) from a single material may be spirally wound to form an elongate tube. The elongate hollow body itself may in transverse cross-section have a thin wall portion and a relatively thicker or more rigid reinforcement portion. The tubes can be incorporated into a variety of medical circuits or may be employed for other medical uses.

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 medical tube comprises a tail to connect an embedded wire to an electrical component. The tail may comprise a flattened portion and an exposed portion to facilitate attachment of the medical tube to an electrical component. The tail may comprise a second flattened portion. One or more wires, such as a heater wire or a sensor wire, may be embedded in the medical tube. The medical tube may comprise a connector that comprises a printed circuit board to which the one or more wires is attached. The connector may comprise features to support the printed circuit board, aid in assembly of the one or more wires to the connector, and protect electrical components against liquid ingress.
