Abstract

The invention discloses a capacitance infusion monitoring method and device. The method and device are used for detecting the infusion state (infusion speed, abnormal interrupt and infusion finishing) of an infusion device. The infusion device comprises a dropper and an infusion pipeline. The capacitance measuring method infusion monitoring device comprises a capacitor, a capacitance sensor and a controller. The capacitor is connected with the controller through the capacitance sensor. The capacitor is composed of two capacitor polar plates arranged on the two sides of the dropper of the infusion device respectively. The capacitance sensor is used for collecting the capacitance value between the two capacitor polar plates and sending the capacitance value to the controller. The controller obtains the infusion state according to changes of the capacitance value. According to the technical scheme, the simple capacitor is adopted to serve as a measuring device, the structure is simple, sensitivity is high, and the infusion state can be monitored in real time.

Description

technical field [0001] The invention relates to medical equipment, in particular to a capacitive transfusion monitoring method and device. Background technique [0002] At present, the most widely used infusion monitoring methods are: (1) infusion bottle (bag) quality detection method: during the infusion process, as the weight of the infusion bottle (bag) decreases, the circuit is driven by detecting the weight change, thereby detecting the infusion state. This method has single function and low sensitivity. (2) Photoelectric detection method: through the photoelectric sensor fixed on the infusion tube, the state of infusion is detected by the reflection or refraction of light. Since this method adopts liquid level detection and involves photoelectric detection, it also has the disadvantages of low sensitivity and weak anti-interference ability. This method is not suitable for some light-proof drug injections. (3) capacitance measurement method: the present invention bel...
