摘要：
A respiratory humidifier chamber for use with a breathing assistance apparatusis described. The chamber comprises a watertight vessel having an inlet for receivinggases from the breathing assistance apparatus, and an outlet through which heatedhumidified gases exit the vessel for delivery to a patient. The chamber has a partitionwhich divides the chamber into upstream and downstream sub-chambers. The sub-chambersare separated by the partition except for an aperture which passes through thepartition and allows gaseous communication between the sub-chambers. The downstreamsub-chamber includes a heater base which heats a volume of water contained withinit. The aperture is located above the volume of water. The upstream sub-chambercontains an internal heater which heats gases passing through it from the inletto the aperture. At least part of the internal heater is located immediately adjacentthe aperture.
