全脸面罩的阀装置
摘要：
一种阀装置(60)用于具有框架部分(16)的患者接口设备(10)。所述阀装置包括阀构件(36)，所述阀构件具有耦合部分(44)和从所述耦合部分延伸的阻挡部分(46)。所述阀构件的所述耦合部分被构造为耦合到所述框架部分。所述阻挡部分被构造为在第一位置与第二位置之间移动；所述阀装置还包括防护构件(40)，所述防护构件具有耦合部分(48)和所述防护构件的所述耦合部分延伸的保护部分(50)。所述防护构件的所述耦合部分被构造为耦合到所述框架部分。当阀构件的阻挡部分从所述第一位置向所述第二位置移动时，所述阻挡部分朝向所述防护构件的所述保护部分移动。
摘要（英）：

A valve arrangement (60) is for a patient interface device (10) having a frame portion (16). The valve arrangement includes a valve member (36) having a coupling portion (44) and a blocking portion (46) extending from the coupling portion. The coupling portion of the valve member is structured to be coupled to the frame portion. The blocking portion is structured to move between a first position and a second position. The valve arrangement further includes a guard member (40) having a coupling portion (48) and a protecting portion (50) extending from the coupling portion of the guard member. The coupling portion of the guard member is structured to be coupled to the frame portion. When the blocking portion of the valve member moves from the first position toward the second position, the blocking portion moves toward the protecting portion of the guard member.
