摘要
为减轻护士的劳动强度、患者家属负担、保证输液安全,文中通过采用光电式、电容式、超声、力学、图像等液位检测方法,设计了一种输液监视报警装置。通过监视物理量的变化,以实时监控液位信息,再将相关信号传送到后续报警电路,从而实现自动报警。实验证明,该设计可以有效实现对药液液位的监测、报警、显示等功能。
To reduce the labor intensity of nurses, the burden on the families of patients, to ensure the safety of the infusion, the level detection method using optical, capacitive, ultrasonic, mechanical, images, design an infusion monitoring alarm device changes by monitoring physical quantities. Monitoring liquid level information in real time, then the relevant signal sent to the follow-up alarm circuit, in order to achieve the automatic alarm. Experiments show that the design can be an effective solution liquid level monitoring, alarm display functions.
