Problems solved by technology
The device for monitoring the infusion in the prior art basically uses the motor rotating mechanism to drive the clip or the fixed piece to intercept the flow, that is, when an abnormal situation is found or the liquid medicine in the infusion bottle is dripped out, the liquid in the infusion tube is blocked to make the liquid No longer flow and stop the infusion, these similar methods have the following disadvantages, first, the structure is complex, because there are many transmission links, so the possibility of failure is large
Second, the motor used in the device has high torque, high power consumption and heavy weight, and the device is easy to fall off from the thin infusion tube

Description
technical field [0001] The invention relates to the field of automatic monitoring, in particular to a medical infusion shut-off device with automatic monitoring. Background technique [0002] In the process of infusion therapy for patients, it is very necessary to monitor the infusion process. The device for monitoring the infusion in the prior art basically uses the motor rotating mechanism to drive the clip or the fixed piece to intercept the flow, that is, when an abnormal situation is found or the liquid medicine in the infusion bottle is dripped out, the liquid in the infusion tube is blocked to make the liquid No longer flow and stop the transfusion, these similar methods have the following disadvantages, the first, complex structure, because there are many transmission links, so the possibility of failure is large. The 2nd, the motor torque that device adopts is big, and power consumption is big and weight is heavy, and device is easy to fall off from thin transfusio...
