医院应用中心吸引系统,手术中吸引瓶吸入过多液体,而使液体吸入墙内金属管道中,造成管道锈蚀,堵塞等事故。采用本报警器可以及时报警,有效地预防上述情况的发生。工作原理报警器由电池、报警电路、液面电极(电极棒周围必须绝缘、二极相距≥3cm),扬声器等组成。电路见附图。
The hospital application center attracts the system, attracts the bottle to inhale too much liquid during the operation, and the liquid is sucked into the metal pipe in the wall, causing the pipe to rust and block. The alarm can be used in time to effectively prevent the occurrence of the above situation. Working principle The alarm consists of a battery, an alarm circuit, a liquid surface electrode (insulated around the electrode rod, a distance between the two poles ≥ 3cm), and a speaker. Circuits see the attached drawings.
