放射科医师在给病人做透视和胃肠检查时,要在暗室中交替开关X线机和室内红灯感到很不方便,有时甚至引起操作失误。为了避免在暗室里摸开关,我们将原机的电源开关改用普通拉线开关,并使x线机和红灯联动。工作时,合上墙闸,红灯就亮;拉动拉线开关,X线机得电,红灯熄灭;再拉开关,机器关闭,红灯又亮。通过这样改接,可用一个动作完成开(关)机关(开)灯的任务。另外把拉线开关装在顺手的地方,伸手可及,在暗室中使用更觉方便。其改接线路如图所示。 ZK是墙上电源总闸;BX是熔断器;K
When radiologists perform fluoroscopy and gastrointestinal examinations on patients, it is inconvenient to switch X-ray machines and indoor red lights alternately in a dark room, sometimes causing operational errors. In order to avoid touching the switch in the darkroom, we will use the ordinary pull switch to switch the power switch of the original machine, and make the x-ray machine and red light linkage. When working, close the wall gate and the red light will turn on; pull the pull switch, the X-ray machine will get power, and the red light will go out; then pull the switch, the machine will turn off and the red light will turn on. By changing the connection in this way, you can use one action to complete the task of turning on (off) the organ (on) light. In addition, the cable switch is installed in a convenient place, within easy reach, and is more convenient to use in the darkroom. Its connection line is as shown in the figure. ZK is the wall power main gate; BX is the fuse; K
