    Abstract: A flow regulation vent includes a fixed portion adapted to engage a gas supply conduit and a spring force biased movable portion connected by a hinge to the fixed portion and flowingly connected to the pressurized gas supply. The fixed portion includes a gas flow orifice. The movable portion is pivotably movable between 1) a relaxed position, wherein at a specified minimum operating pressure, the movable portion is pivoted by the spring force away from the fixed portion to a position to establish a first gas washout flow area between the movable portion and the gas flow orifice; and 2) a fully pressurized position, wherein at a specified maximum operating pressure, the pressurized gas offsets the spring force to pivot the movable portion to a position adjacent the fixed portion to establish a minimum gas washout flow area between the movable portion and the gas flow orifice.

    Abstract: An elbow assembly includes an elbow with an opening in a sidewall of the elbow. An anti-asphyxia valve (AAV) assembly is provided to the elbow. The opening in the sidewall of the elbow is configured to receive at least a portion of the AAV assembly. The elbow assembly further includes a support member with an atmospheric port. The support member is configured to be secured to a portion of the elbow and cover the opening. The AAV assembly is adapted to be secured to the elbow by the support member. In addition, the support member is configured so that an outer surface of the support member is substantially flush with an outer surface of the elbow when the support member is secured to the portion of the elbow.

    Abstract: A respiratory mask assembly for delivering breathable gas to a patient includes a frame having a front surface and a rear surface, opposite the front surface, and adapted in use to face the patient. The frame defines an inner wall and an outer wall extending from the rear surface, the inner and outer walls being spaced to define a channel therebetween. A cushion is removably attachable to the frame such that the cushion and frame are repeatably engagable with and disengagable from one another. The cushion includes a side wall to be inserted into the channel of the frame, the side wall having a first interlocking surface that engages a second interlocking surface provided in the channel when the cushion and frame are engaged with one another. The first and second interlocking surfaces interlock with one another to removably attach the cushion to the frame.

    Abstract translation: 用于向患者输送透气性气体的呼吸面罩组件包括具有与前表面相对的前表面和后表面的框架，并且适于在使用中面对患者。 框架限定了从后表面延伸的内壁和外壁，内壁和外壁间隔开以限定其间的通道。 垫子可移除地附接到框架上，使得衬垫和框架可重复地与彼此接合和分离。 该衬垫包括一个待插入框架通道的侧壁，该侧壁具有一第一互锁表面，该第一联锁表面在该衬垫和框架彼此接合时与设在通道中的第二互锁表面接合。 第一和第二互锁表面彼此互锁以将缓冲垫可拆卸地附接到框架。
