    Abstract: 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.

    Abstract translation: 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。
