Background
The infusion tube is clamped between two capacitor plates according to the phenomenon that the dielectric constant of the infusion tube can change when liquid exists or does not exist in the infusion tube, whether the liquid exists in the infusion tube or not can be judged by measuring the change of the capacitor capacity, and when the liquid is dripped out or the infusion is abnormal, a channel can be automatically cut off and an alarm is given out, so that the purpose of monitoring the infusion is achieved.
The humidity-sensitive capacitor is generally made of a polymer film capacitor, and the commonly used polymer materials include polystyrene, polyimide, cellulose acetate, and the like. When the environmental humidity changes, the dielectric constant of the humidity sensitive capacitor changes, so that the capacitance of the humidity sensitive capacitor also changes, and the capacitance change quantity of the humidity sensitive capacitor is in direct proportion to the relative humidity. The humidity-sensitive capacitor has the main advantages of high sensitivity, good product interchangeability, high response speed, small humidity hysteresis, convenient manufacture, easy realization of miniaturization and integration, and generally lower precision than that of the humidity-sensitive resistor. The humidity-sensitive capacitor is manufactured by Humirel corporation, Philips corporation, Siemens corporation and the like. In the case of SH1100 type moisture sensitive capacitor manufactured by Humirel corporation, the measurement range is (1% to 99%) RH, and the capacitance at 55% RH is 180pF (typical value). When the relative humidity is changed from 0 to 100%, the capacitance is changed in a range of 163pF to 202 pF. The temperature coefficient was 0.04 pF/deg.C, the humidity hysteresis was + -1.5%, and the response time was 5 s.
The existing transfusion alarm adopts a method of predicting and monitoring the flow velocity of liquid drops or detecting the stock of liquid medicine by adopting a weighing method, and has the problems of complex equipment, inconvenient operation and easy misalignment of precision.
