MICROFLUIDIC PUMP-BASED INFUSION ANOMALY STATE DETECTION AND CONTROL SYSTEM

The present invention provides a microfluidic pump-based infusion anomaly state detection and control system, comprising: a microfluidic pump chip configured to control the vibration of an actuating device to output a liquid; a pressure sensor located in a pipeline behind the outlet of the microfluidic pump chip and configured to sense the change of the pressure of the liquid output by the microfluidic pump chip to output an electric signal; a signal conditioning circuit configured to perform signal conditioning on the electric signal to obtain a conditioned electric signal; a signal acquisition circuit configured to convert the conditioned electric signal from an analog signal into a digital signal; a signal processing unit configured to determine the working state of the microfluidic pump chip and the working state of an infusion pipeline according to the digital signal, and to send a signal to an alarming unit when an anomaly is found; the alarming unit configured to alarm according to the signal; and a control drive unit configured to adjust the output state of the microfluidic pump chip according to the output of the signal processing unit. The present invention can precisely control a microfluidic pump chip and accurately detect the anomaly state of the microfluidic pump chip and alarm in time.
