    • The present invention provides a system for endoscopes which can supply air and water according to each application by regulating air and water flow rates independently. Although air and water may be supplied with one pump, the present invention controls air and water flow rates separately by using an air supply pump and water supply pump and by controlling a plurality of open-close valves installed, for example, on atmospheric escape pipes. The air channel and water channel are connected, for draining, by a first connecting pipe. If the air supply pump is used also for water supply and the water supply pump is used also for air supply, it is possible to supply air and water at a high flow rate fast enough even for high-speed water injection. If a fixed flow rate is used for a specified time at the start, specific operations can be simplified.
    • 本发明提供了一种内窥镜系统,其能够通过独立地调节空气和水流速来根据每种应用来供应空气和水。 虽然空气和水可以供应一个泵,但是本发明通过使用供气泵和供水泵来分别控制空气和水流量,并且通过控制多个开关阀,例如安装在大气排放管 。 空气通道和水通道通过第一连接管连接,用于排水。 如果供气泵也用于供水,供水泵也用于空气供应,则即使高速注水也能够以足够高的流速供应空气和水。 如果在开始时使用固定的流量达指定时间,则可以简化特定的操作。

    • An endoscope is provided in which the advantage of a pinch valve is used, and the flow rate of fluid can be regulated variably. In an electromagnetic valve unit for carrying out the opening/closing control of pipes in the endoscope, a pinch valve is disposed in a water feed pipe, and a diaphragm valve is disposed in an air feed pipe. Also, for ease of draining work, an air feed pipe is connected to the water feed pipe, an auxiliary valve consisting of a diaphragm valve is disposed, and a check valve is installed. Further, for example, three control pipes with different diameters and three electromagnetic valves for opening/closing these control pipes are provided in each pipe. By carrying out the opening/closing control of these electromagnetic valves by using an operation switch, the flow rate in each pipe in the endoscope is regulated variably. Also, for the suction pipe in the endoscope, by providing, for example, three open-to-atmosphere pipes with different diameters and three electromagnetic valves, the flow rate of the suction pipe can be regulated variably.
    • 提供了一种使用夹管阀的优点的内窥镜,并且可以可变地调节流体的流量。 在用于执行内窥镜中的管道的打开/关闭控制的电磁阀单元中,夹送阀设置在给水管中,并且隔膜阀设置在供气管中。 此外,为了便于排水工作,将供气管连接到给水管,设置由隔膜阀组成的辅助阀,并安装止回阀。 此外,例如,在每个管道中设置有具有不同直径的三个控制管和用于打开/关闭这些控制管的三个电磁阀。 通过使用操作开关进行这些电磁阀的打开/关闭控制,能够可变地调节内窥镜中各管的流量。 此外,对于内窥镜中的吸入管,通过设置例如具有不同直径的三个开放式大气管和三个电磁阀,可以可变地调节吸入管的流量。
