Abstract: An exchanger conduit permits temperature and/or humidity conditioning of a gas for a patient respiratory interface. In an example embodiment, a conduit has a first channel and a second channel where the first channel is configured to conduct an inspiratory gas and the second channel configured to conduct an expiratory gas. An exchanger is positioned along the first channel and the second channel to separate the first channel and the second channel. The exchanger is configured to transfer a component (e.g., temperature or humidity) of the gas of the second channel to the gas of the first channel. In some embodiments, an optional flow resistor may be implemented to permit venting at pressures above atmospheric pressure so as to allow pressure stenting of a patient respiratory system without a substantial direct flow from a flow generator of respiratory treatment apparatus to the patient during patient expiration.

Abstract translation: 交换器管道允许用于患者呼吸界面的气体的温度和/或湿度调节。 在一个示例性实施例中，导管具有第一通道和第二通道，其中第一通道被配置为传导吸气气体，而第二通道被配置为传导呼气。 交换机沿着第一通道和第二通道定位以分离第一通道和第二通道。 交换器被配置为将第二通道的气体的部件（例如，温度或湿度）传送到第一通道的气体。 在一些实施例中，可以实施任选的流阻器，以允许在高于大气压力的压力下排气，从而允许患者呼吸系统的压力支架，而在患者呼出期间没有从呼吸治疗设备的流量发生器到患者的实质性直接流动。
