    Abstract: The present invention provides a vent assembly suitable for use with a respiratory mask of the type used in CPAP treatment. In one embodiment the vent is made of a thin air permeable membrane. Generally, the membrane is thinner than 0.5 mm. The membrane can be made of a hydrophobic material such as polytetrafluoroethylene (PTFE). The membrane can also be fabricated from expanded PTFE. The expanded PTFE membrane is mounted on a polypropylene scrim. The pores of the membrane have a reference pore size of 10 to 15 microns. In an alternative embodiment, the vent assembly includes a vent constructed from stainless steel. In another embodiment the membrane has a superficial cross-sectional area of approximately 500 mm2. In another embodiment the vent assembly comprises a membrane attached to a vent frame, the vent assembly forming an insert which can be removeably attached to a mask fame.

    Abstract translation: 本发明提供一种适合与CPAP治疗中使用的呼吸面罩一起使用的通气口组件。 在一个实施例中，通风口由薄透气膜制成。 通常，膜比0.5mm薄。 膜可以由诸如聚四氟乙烯（PTFE）的疏水材料制成。 膜也可以由膨胀PTFE制成。 膨胀PTFE膜安装在聚丙烯稀松布上。 膜的孔具有10至15微米的参考孔径。 在替代实施例中，排气组件包括由不锈钢构成的通风口。 在另一个实施方案中，膜具有约500mm 2的表面横截面积。 在另一个实施例中，排气组件包括附接到排气口框架的隔膜，排气组件形成可以可移除地附接到面罩构件的插入件。

    Abstract: A seal is provided for a chassis assembly of a flow generator configured to provide a flow of breathable gas. The chassis assembly includes an upper chassis and a lower chassis. The seal includes a blower receptacle sealing portion configured to seal a blower receptacle of the chassis assembly configured to receive a blower configured to generate the flow of breathable gas; a flow sensor sealing portion configured to seal a flow sensor provided in the chassis assembly and configured to measure the flow of breathable gas; a blower mount configured to receive a portion of the blower and mount the blower to the seal; and a blower mount suspension configured to connect the blower mount to the blower receptacle sealing portion, wherein in an assembled condition the seal and the chassis assembly define a flow path from an inlet of the chassis assembly to the blower receptacle of the chassis assembly to an outlet of the chassis assembly. A flow generator for generating a flow of breathable gas includes a chassis assembly comprising a lower chassis and an upper chassis, the lower chassis and the upper chassis defining a blower receptacle; a blower provided in the blower receptacle; and the seal.

    Abstract: A vent assembly for use with a respiratory mask of the type used in CPAP treatment. In one embodiment, the vent is made of a thin air permeable membrane. The membrane can be made of a hydrophobic material such as expanded polytetrafluoroethylene (PTFE). An expanded PTFE membrane is mounted on a polypropylene scrim. The pores of the ePTFE membrane have a reference pore size of 10 to 15 microns. Alternatively, the vent assembly includes a stainless steel vent having holes with diameters less than about 0.2 mm. In another embodiment, the membrane has a superficial cross-sectional area of approximately 500 mm2. In further embodiments, a vent of a mesh material, e.g., an auxetic vent or a PTFE mesh, may be used as an air permeable membrane, either alone or in combination with a traditional vent structure.
