    • A respiratory humidifier chamber for use with a breathing assistance apparatus is described. The chamber includes a water-tight vessel having an inlet for receiving gases from the breathing assistance apparatus, and an outlet through which heated humidified gases exit the vessel for delivery to a patient. The chamber has a partition which divides the chamber into upstream and downstream sub-chambers. The sub-chambers are separated by the partition except for an aperture which passes through the partition and allows gaseous communication between the sub-chambers. The downstream sub-chamber includes a heater base which heats a volume of water contained within it. The aperture is located above the volume of water. The upstream sub-chamber contains an internal heater which heats gases passing through it from the inlet to the aperture. At least part of the internal heater is located immediately adjacent the aperture.
    • 描述了与呼吸辅助装置一起使用的呼吸加湿器室。 腔室包括具有用于接收来自呼吸辅助装置的气体的入口的水密容器,以及加热的加湿气体通过该出口离开容器以输送给患者的出口。 该室具有将室分成上游和下游子室的隔板。 这些分室除了通过分隔件的孔之外还被分隔开,并允许子室之间的气体连通。 下游副室包括加热器底座,其加热容纳在其中的水的体积。 孔径位于水的体积之上。 上游副室包含一个内部加热器,它将从入口通过的气体加热到孔。 内部加热器的至少一部分位于紧邻孔的位置。
