    Abstract: A non-rebreathing valve assembly having a body formed of first and second parts with a circular diaphragm assembly disposed between the parts. The diaphragm assembly has a flexible circular diaphragm having its outer margin secured to the first and second parts. The diaphragm is provided with a plurality of holes spaced between the inner portion and the outer margin of the diaphragm which are normally closed by a one-way flapper valve member carried by the diaphragm assembly. The first part is provided with a centrally disposed exhaust opening which is adapted to be closed by the diaphragm assembly. The first part is also provided with a flow passage adapted to be placed in communication with a patient and with said holes in said diaphragm when said flapper valve is in open position. The second part has an inlet opening which is in communication with the other side of the diaphragm assembly. The second part if provided with a plurality of openings which open to ambient. A one-way flapper valve is carried by the second part and normally closes the openings. When utilized as a resuscitator, a compression bulb is secured to the inlet of the second part. For automatic operation, the inlet, in addition, is secured to a source of gas under pressure which is controlled by a controller.

    Abstract translation: 一种非再呼吸阀组件,其具有由第一和第二部分形成的本体,该主体具有设置在所述部分之间的圆形隔膜组件。 隔膜组件具有柔性圆形隔膜,其外边缘固定到第一和第二部分。 隔膜设置有间隔开的隔膜的内部部分和外缘之间的多个孔,这些孔通常由隔膜组件承载的单向挡板阀构件封闭。 第一部分设置有中心设置的排气口,其适于由隔膜组件封闭。 第一部分还设置有流动通道,其适于在所述挡板阀处于打开位置时被放置成与患者连通并且具有所述隔膜中的所述孔。 第二部分具有与隔膜组件的另一侧连通的入口开口。 第二部分如果设有多个开放到环境的开口。 单向挡板阀由第二部分承载并且通常关闭开口。 当用作复苏器时,压缩灯泡被固定到第二部分的入口。 对于自动操作,入口另外被固定在由控制器控制的压力下的气体源。
