Integrated humidifier chamber and lid

An integrated blower and humidification system for providing heated humidified gases to a user, the system comprising:

• a blower unit;
• and
• a humidification chamber;
• the blower unit comprising:
• an outer casing which encloses and forms part of the blower unit, the outer casing including a front face that is angled rearwards, the front face comprising user inputs;
• an air inlet on a wall of the outer casing, through which air from atmosphere can enter the outer casing when in use;
• a humidifier compartment defined at least in part by a cavity formed from a bottom wall and at least an upwardly extending wall, and comprising a compartment port in the cavity on the wall which, in use, receives and holds the humidification chamber;
• a gases path through the outer casing between the air inlet and the compartment port;
• a fan unit contained within the outer casing in the gases path between the air inlet and the compartment port, the fan unit, which in use, draws air in through the air inlet and provides a pressurized gases stream to the compartment port;
• a heater base on the bottom wall of the humidifier compartment;
• and
• a power supply unit located within the outer casing and adapted to, in use, provide power to the blower unit;
• wherein the blower unit, in use, receives the humidification unit at least partially into the cavity of the humidifier compartment;
• and
• the humidification chamber comprising:
• dimensions which conform to the cavity such that the humidification chamber aligns with the cavity and the outer casing to form a discrete integrated device, wherein the humidification chamber conforms to an internal shape and is confined within external dimensions of the blower unit when the humidification chamber is received and held by the humidification compartment;
• a humidifier inlet port, which in use receives the pressurized gases stream from the compartment port;
• a heat conducting surface, which in use heats a volume of water in conjunction with the heater base, the heat conducting surface being on a bottom side of the humidification chamber;
• and
• an outlet connection, which in use connects directly to a conduit providing a fluid pathway between the humidification chamber and a patient interface, wherein, in use, the pressurized gases stream exits the compartment port of the blower unit and enters the humidifier chamber where it is humidified and heated before passing out of the humidifier chamber, through the outlet connection, and to the user via the conduit;
• wherein the outlet connection is adapted to allow simultaneous combined pneumatic and electrical connection between the integrated blower and humidification system and the conduit.
