|
摘要
目的为了更好地监控存在液路系统的医疗设备的漏液情况,及时对设备漏液情况进行处理,设计了一套漏液监测报警系统。方法结合目前许多存在液路系统的医疗设备的特点,利用LM393电压比较器,结合大面积漏液传感器以及外围电路,设计了一套漏液监测报警系统。结果根据漏液监测原理制作了漏液监测报警系统,该系统可以在设备内部存在漏液时及时有效地以声光报警的形式告知工作人员,使工作人员能够尽早地发现设备漏液并做相应处理,降低损失。结论利用该漏液监测报警系统可以实现漏液监测报警,值得推广应用。
Objective In order to better monitor the leakage of medical equipment in the liquid channel system, and deal with the leakage in time, a leakage monitoring and alarm system is designed. Methods Combined with the characteristics of many medical devices with liquid channel system, a leakage monitoring and alarm system was designed using LM393 voltage comparator combined with large-area leakage sensor and peripheral circuit. Results According to the principle of liquid leakage monitoring, a liquid leakage monitoring and alarming system was prepared, which could effectively inform the staff in the form of sound-light alarm in time when there was liquid leakage inside the equipment. Thus the staff could ?nd the liquid leakage of the equipment as soon as possible and did the corresponding treatment to reduce the loss. Conclusion The system can be used to monitor and alarm the leakage of liquid, which is worth popularizing.
