摘要： A selector valve for use with a hospital vacuum or positive pressure module to supply vacuum or pressure to a utilisation means. The selector valve has two or more positions and includes a positive stop at each of its positions through the use of moulded plastic parts that interact together to eliminate springs or other components that are tedious to assemble. The entire selector valve is comprised of a minimum of parts and costly lapped surfaces are eliminated by moulding a gasket material to one of the components of the valve. The overall multi-position selector valve is thus inexpensive to manufacture by utilising a minimal number of plastic moulded parts and that are easy to assemble.

摘要： An intermittent suction regulator is disclosed operating from a vacuum system and is used to provide a plurality of pneumatic output signals to a positive pulse device for returning fluids removed from a patient during drainage thereof to clear the removal passageways. The suction regulator or control unit provides two (2) timed output signals, from one (1) intermittent vacuum to atmospheric pressure input. One output signal continually switches from a regulated vacuum signal to an atmospheric pressure signal while the other output signal switches from providing an unregulated vacuum signal to an atmospheric pressure signal. The signals are timed such that both are initially set to provide vacuum signals simultaneously, however there is a predetermined time delay between the time the regulated vacuum output signal switches from vacuum to atmospheric and when the unregulated vacuum output signal switches from vacuum to atmospheric. Both output signals, however, again switch back to their vacuum signals simultaneously after a predetermined cycle time.

摘要翻译： 公开了一种间歇抽吸调节器，其从真空系统操作并且用于向正脉冲装置提供多个气动输出信号，用于在排液期间返回从患者排出的流体以清除移除通道。 抽吸调节器或控制单元提供两（2）个定时输出信号，从一（1）个间歇真空到大气压输入。 一个输出信号从调节的真空信号连续地切换到大气压信号，而另一个输出信号从提供未调节的真空信号切换到大气压信号。 信号被定时，使得两者最初被设置为同时提供真空信号，但是在调节的真空输出信号从真空切换到大气之间以及当未调节的真空输出信号从真空切换到大气时，存在预定的时间延迟。 然而，两个输出信号在预定的周期时间之后再次切换回它们的真空信号。
