    • The present invention relates to a vacuum demand valve (50) for use on the exhalation side of a breathing apparatus (32) for controlling the flow of exhalation gases from a patient (34) to a vacuum line (36). The demand valve comprises: a housing (1, 14) having a housing inlet (2) which can be connected to an exhalation line (40) of a breathing apparatus to allow exhalation gases to flow into the housing from a patient and a housing outlet (3) which can be connected to a vacuum line to allow gases to flow from the housing into the vacuum line; a diaphragm (4) having a flexible skirt (4b) connected to the housing and a rigid portion (4a) supported by the flexible skirt and moveable in response to gas pressure in the housing; a sealing member (10) connected to the rigid portion of the diaphragm which can engage with the housing outlet to resist the flow of gases from the housing to the vacuum line; wherein in a first condition of the diaphragm, the pressure in the vacuum line causes the sealing member to engage the housing outlet for resisting flow of gases from the housing to the vacuum line and in a second condition of the diaphragm a predetermined pressure of exhalation gases in the housing acts on the rigid portion of the diaphragm causing the sealing member to disengage at least partially from the housing outlet allowing exhalation gases to flow from the housing to the vacuum line.
    • 本发明涉及一种在呼吸器(32)的呼气侧使用的用于控制从患者(34)到真空管线(36)的呼出气体流动的真空需求阀(50)。 所述需求阀包括:具有壳体入口(2)的壳体(1,14),所述壳体入口可连接到呼吸设备的呼出管线(40),以允许呼出气体从患者和外壳出口流入所述壳体 (3),其可以连接到真空管线以允许气体从壳体流入真空管线; 具有连接到所述壳体的柔性裙部(4b)的隔膜(4)和由所述柔性裙部支撑并且可响应于所述壳体中的气体压力而移动的刚性部分(4a) 连接到隔膜的刚性部分的密封构件(10),其可与壳体出口接合以抵抗气体从壳体到真空管线的流动; 其中在所述隔膜的第一状态下,所述真空管线中的压力使得所述密封构件与所述壳体出口接合,以阻止气体从所述壳体流到所述真空管线,并且在所述隔膜的第二状态下具有预定的呼出气体压力 在壳体中作用于隔膜的刚性部分,导致密封构件至少部分地脱离壳体出口,允许呼出气体从壳体流到真空管线。

    • The present invention relates to a Resuscitation device (100) comprising a compressible chamber (110) for providing a tidal volume of oxygen-containing gas to a patient, with an inlet (111) for admission of the oxygen-containing gas into the compressible chamber (110), and an outlet (112) for directing, the oxygen containing gas to a patient, the compressible chamber being compressible by means of a lever mechanism (120) comprising at least one pivotable lever (122), the lever mechanism (120) being actable by means of a cam mechanism (130) comprising a cam pivotable about a cam axis (132), wherein the tidal volume of the compressible chamber is adjustable by means of moving the compressible chamber and/or by moving the cam axis (132) of the cam (130) with respect to the at least one lever (122), and/or by moving the lever (122) with respect to the compressible chamber.
    • 本发明涉及一种复苏装置(100),其包括用于向患者提供含氧气体的潮气量的可压缩室(110),其具有用于将含氧气体进入可压缩室的入口(111) (110),以及用于将含氧气体引导到患者的出口(112),所述可压缩室通过杠杆机构(120)可压缩,所述杠杆机构包括至少一个可枢转杠杆(122),所述杠杆机构 )可通过包括可围绕凸轮轴线(132)枢转的凸轮的凸轮机构(130)起作用,其中通过移动可压缩室和/或通过移动凸轮轴线来调节可压缩室的潮气量( 相对于所述至少一个杠杆(122)的凸轮(130)的旋转轴(132),和/或通过相对于可压缩室移动杠杆(122)。
