    • A gas vent valve assembly may be attached or incorporated to a disposable fluid transfer set used with a fluid warmer to administer an infusate to a patient. The gas vent valve assembly has a housing having a fluid inlet, a gas outlet and a fluid outlet. The gas outlet is located at the top of the housing while the fluid outlet is located at the bottom of the housing. Inside the housing is an actuator float that has an upper seal and a lower seal. The dimension of the float relative to the chamber of the housing is such that the float is freely movable within the housing to an upper position whereby its upper seal closes the gas outlet while the fluid outlet is opened, and to a lower position whereby its lower seal closes the fluid outlet and the gas outlet is opened.
    • 气体排出阀组件可以连接或并入到与流体加热器一起使用的一次性流体传送装置,以向患者施用输注物。 排气阀组件具有壳体,该壳体具有流体入口,气体出口和流体出口。 气体出口位于壳体的顶部,而流体出口位于壳体的底部。 外壳内部是一个执行器浮子,具有上密封和下密封。 浮体相对于壳体的腔室的尺寸使得浮子可在壳体内自由移动到上部位置,由此其上部密封件在流体出口打开时封闭气体出口,并且在较低位置处其下部 密封件关闭流体出口并打开气体出口。
