Claim 19:
20. A removable humidification unit which in use is inserted into a blower unit and receives and humidifies a pressurized gases stream to form an integrated blower and humidification system, the removable humidification unit comprising:
a guide which orients the removable humidification unit in a humidifier compartment of the blower unit;
a spring loaded clip which in use releasably locks the removable humidification unit in the humidifier compartment of the blower unit, the spring loaded clip released by a button to remove the humidification unit from the humidifier compartment;
a humidifier inlet port which in operation receives the pressurized gases stream from the blower unit;
a heat conducting surface which in operation heats a volume of water in conjunction with the blower unit;
a humidifier chamber which in operation heats and humidifies the pressurized gases stream;
an outlet connection; and
a conduit connected directly to the outlet connection and which in operation provides a fluid pathway between the outlet connection and a patient interface, wherein in use the pressurized gases stream will exit a compartment inlet port of the blower unit and enter the humidifier chamber, where it is humidified and heated, before passing out of the humidifier chamber, through the outlet connection, and to a user via the conduit;
wherein the heat conducting surface is entirely vertically oriented; and
wherein the humidification unit is inserted into the humidifier compartment of the blower unit in a vertical direction, guided into position by the guide, and secured in position within the humidifier compartment of the blower unit by the spring loaded clip, causing the heat conducting surface to align with a heater base of the humidifier compartment of the blower unit, and the humidifier inlet port to align with the compartment inlet port of the humidifier compartment of the blower unit.
