    Abstract: A fluidistor fluid control device comprising a plurality of channels such as Laval nozzles, each channel extending from a control jet inlet to an outlet, such that the direction of flow of fluid through the channel is dependent on the relative flow characteristics of the channels. These flow characteristics can be varied by varying the shape or size of the channels, or by applying a separate control fluid to the interior of one or more of the channels.

    Abstract: A gas evacuator for removing excess gas conveyed to a patient through a duct from a gas supply. The device includes a conduit connectable to the gas duct to convey the gas from one portion of the duct to another portion thereof. A chamber is provided with a drain line connectable to a low pressure source, such as a vacuum pump, for maintaining a reduced pressure in the chamber. A first valve is provided for venting excess gas from said conduit to said chamber in response to the differential pressure therebetween. A second valve is provided to introduce gas to said chamber from atmosphere in response to pressure in the chamber. The chamber is kept under low pressure by the vacuum pump. At a desired value of low pressure, the second valve opens to maintain that pressure in the chamber. If excess gas is present in the duct, the first valve opens venting that excess gas to the chamber until the excess gas is removed. The vented gas is removed through the drain line. In the event of a temporary increase in pressure in the chamber above the mentioned desired value, the second valve closes thus ensuring that the excess gas removed from the duct is not vented to atmosphere in the area adjacent the device.

    Abstract translation: 一种气体抽出器，用于通过管道从气体输送器中输送到患者的多余气体。 该装置包括可连接到气体管道的导管，以将气体从管道的一部分输送到其另一部分。 腔室设置有可连接到低压源（例如真空泵）的排水管线，用于保持腔室中的减压。 提供第一阀，用于响应于它们之间的压差，将多余的气体从所述导管排放到所述腔室。 提供第二阀，以响应腔室中的压力将气体从大气引入到所述腔室。 通过真空泵将室保持在低压下。 在期望的低压值下，第二阀打开以保持腔室中的该压力。 如果管道中存在过量的气体，则第一阀打开通向腔室的过量气体，直到除去多余的气体。 排出的气体通过排出管线去除。 在室内的压力临时增加超过所述期望值的情况下，第二阀关闭，从而确保从管道移除的过量气体不会在与设备相邻的区域中排放到大气中。
