    • A patient interface for use in delivering a flow of breathable gas to an airway of a patient includes a first seal adapted to contact the patient's face and seal a first space between the patient interface and the patient's face at a first positive pressure; and a second seal adapted to contact the patient's face and seal a second space between the patient interface and the patient's face at a second positive pressure. The first seal also seals the first space from the second space. A leak reducing element may be provided on a seal to reduce and/or diffuse leakage of gas. A vacuum line configured to create a negative pressure may be provided in the second space to remove any gas leaking from the first space to the second space. A seal may be connected to a conduit for delivering the flow of gas that is incorporated into a frame of the patient interface. The seal may be inflatable by the flow of breathable gas to pressurize the seal against the patient's face and include a vent that directs the flow of breathable gas to a space between the patient interface and the patient's face. A cuff may be provided over the seal in the nasal bridge region to direct any leakage of the gas flow from the seal in the nasal bridge region in a direction away from the patient's eyes.
    • 用于将可呼吸气体流传送到患者气道的患者接口包括适于接触患者面部并以第一正压力密封患者接口和患者面部之间的第一空间的第一密封件; 以及第二密封件,其适于接触患者的面部并以第二正压力密封患者接口和患者面部之间的第二空间。 第一个密封件也将第一个空间与第二个空间密封。 泄漏减少元件可以设置在密封件上,以减少和/或扩散气体泄漏。 构造成产生负压的真空管线可以设置在第二空间中以去除从第一空间泄漏到第二空间的任何气体。 密封件可以连接到用于输送并入到患者界面的框架中的气体流的导管。 密封件可以通过可呼吸气体的流动而膨胀,以将密封件压靠在患者的脸部上,并且包括将可呼吸气体流引导到患者接口和患者面部之间的空间的排气口。 可以在鼻梁区域的密封件上方设置袖带以引导气流从鼻梁区域中的密封件沿远离患者眼睛的方向泄漏。

    • A flow generator for generating a flow of pressurized breathable gas includes a cylindrical housing and a motor supported in the housing. The motor has a shaft having a first end and a second end opposite the first end. The shaft is generally coincident with an axis of the motor. A first impeller is attached to the first end of the shaft and a second impeller is attached to the second end of the shaft. A stator directs an air flow from the first impeller back towards the motor axis. The housing includes an inlet adjacent the first end of the shaft having an inlet axis generally coincident with the motor axis and at least one outlet between the first and second impellers. The at least one outlet has an outlet axis generally tangential to the motor axis. An apparatus for delivering a flow of pressurized breathable gas to a patient includes a flow generator and a casing to contain the flow generator. The casing is configured to engage a part of the patient's body, for example the top of the patient's head, and/or to receive a strap adapted to encircle, for example, the patient's arm or chest. The apparatus further includes at least one delivery conduit to convey the flow of pressurized breathable gas and a patient interface to receive the flow of pressurized breathable gas from the at least one delivery conduit and deliver it to the patient's airways.
    • 用于产生加压可呼吸气体流的流量发生器包括支撑在壳体中的圆柱形壳体和马达。 电动机具有轴,其具有第一端和与第一端相对的第二端。 轴通常与电动机的轴线重合。 第一叶轮附接到轴的第一端,并且第二叶轮附接到轴的第二端。 定子将来自第一叶轮的空气流引导回电机轴线。 壳体包括与轴的第一端相邻的入口,其具有大致与马达轴线重合的入口轴线和在第一和第二叶轮之间的至少一个出口。 至少一个出口具有大致与马达轴线相切的出口轴线。 用于将加压的可呼吸气体流传送到患者的装置包括流发生器和用于容纳流量发生器的壳体。 壳体被构造成接合患者身体的一部分,例如患者头部的顶部,和/或接收适于环绕例如患者的手臂或胸部的带。 该装置还包括至少一个输送管道,用于输送加压的可呼吸气体流和患者界面,以接收来自至少一个输送导管的加压可呼吸气体流并将其输送到病人的气道。
