Abstract

See full text

The present invention comprises a cartridge humidifier assembly having a heating means for humidifying a gas supplied from a source and delivered to a patient. The cartridge humidifier has a cap which defines a chamber with a column. The cap includes a port which receives the gas from a ventilator and a port which permits the discharge of heated humidified gas to the patient. The cap also has a single air-vent port for the venting of air with the water supply from the chamber of cartridge assembly. Water is supplied to the bottom of the cartridge assembly from a one-way conduit in communication with the bottom of the water supply container. A float rises to close off the air-vent when the cartridge assembly is full. The float lowers itself, unblocking the vent to the water bottle supply from the cartridge assembly, as the water level in the cartridge is used up in the humidification process. The float air-vent control is thus automatic, preventing possible overflow or lack of flow of water in the system.
