Abstract

The invention relates to the technical field of liquid leakage detection of medical equipment, and relates to a liquid leakage monitoring alarm circuit of medical equipment. For solving the technicalproblem, the liquid leakage monitoring alarm circuit of medical equipment is provided, wherein when liquid leakage occurs in medical equipment, a liquid leakage monitoring alarm circuit is used for timely and effectively reminding the working personnel in an acousto-optic alarm mode, thereby reducing the loss and saving the maintenance cost. The medical equipment liquid leakage monitoring alarm circuit comprises a liquid leakage sensor, a liquid leakage monitoring module and the like; the input end of the liquid leakage monitoring module is connected with the output end of the liquid leakage sensor, and the liquid leakage sensor is used for detecting whether the equipment suffers from liquid leakage or not. When liquid leakage exists inside the medical equipment, a switch indicator lamp isturned on, a relay drive module works, and an alarm module and a voice drive module are controlled to work, so that the working staff can be informed in the acousto-optic alarm mode, and the workerscan know which equipment suffers from liquid leakage as soon as possible to make corresponding treatment, thereby reducing the loss and saving the maintenance cost.

Description

Technical field [0001] The invention relates to the technical field of medical equipment leakage detection, and relates to a medical equipment leakage monitoring alarm circuit. Background technique [0002] With the continuous advancement of science and technology, there are more and more types of medical equipment. Among many medical equipment, there are many medical equipment with fluid system, among which the most typical medical equipment are hemodialysis device, flow cytometer, angiography machine, automatic biochemical analyzer, automatic blood analyzer, etc. Because this kind of medical equipment has a liquid system, liquid leakage may occur during the working process of the medical equipment. The leakage of the equipment with the liquid system system is unavoidable, and most of the leaked liquid is corrosive, acid-base, etc., which is easy Corrosion of various internal components of medical equipment, causing short circuit of internal circuits of medical equipment, serio...
