Abstract
A humidifier for a CPAP pressurized air generator includes a water tank with a port arrangement protruding into the interior of the tank. The port arrangement includes an inlet, a chimney surrounding the inlet, an outlet, and drain channels. The inlet receives pressurized air output by the CPAP generator and outputs the pressurized air at an opening disposed higher than a maximum fill height of the water tank. The chimney directs the pressurized air output by the inlet to flow out of a number of egress slots and into the tank, the egress slots being disposed lower than the output height of the inlet. The pressurized air gets humidified in the tank and subsequently flows out of the outlet into a conduit for delivery to the airway of a patient. The drain channels divert water out of the water tank once the maximum fill height is reached.
