摘要： 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.

摘要： 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. The fluid inlet is located at a side lower portion 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. The movement of the float is dependent on the respective amounts of air and fluid in the housing, and the buoyancy of the float relative to the fluid in the housing. When a predetermined volume of air gets inside the housing, the float sinks to its lower position to close the fluid outlet and open the gas outlet, so that the air inside the housing is vented to atmosphere while fluid is prevented from being output to the patient. When the amount of gas in the chamber has been reduced to a given volume, with a corresponding increase in the amount of fluid in the housing, the float is raised to open the fluid outlet, thereby enabling the fluid inside the housing to be output to the patient. At that time, the gas outlet is shut to prevent any reverse inflow of air into the housing.

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. The fluid inlet is located at a side lower portion of the housing. Inside the housing is an actuator float that has an upper seal and a lower seal.

摘要翻译：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。流体入口位于壳体的侧下部。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。浮子的运动取决于壳体中空气和流体的相应量，以及浮体相对于壳体中流体的浮力。当预定体积的空气进入壳体内部时，浮子沉到其下部位置以关闭流体出口并打开气体出口，使得壳体内的空气排放到大气中，同时防止流体输出到患者。当腔室中的气体量已经减小到给定的体积时，相应地增加壳体中的流体量，浮起就升高以打开流体出口，从而使壳体内的流体输出到患者。此时，气体出口关闭，以防止空气反向流入外壳。
