AI Technical Summary

Technical Problem

The existing infusion system requires manual control of liquid replacement, and when all the medicine is infused, the liquid level in the infusion tube cannot be automatically shut down when it is lower than the flow controller, making it easy to input air.

Method used

A kind of infusion device that automatically changes and stops fluid is designed, using a parallel infusion part and infrared detector head control system. By monitoring the liquid level position in real time, it automatically controls the opening and closing of the infusion branch and infusion tube to realize automatic liquid change and automatic Stop liquid.

Benefits of technology

It realizes automatic switching to the next bag after the medicine bag is replaced, reducing manual intervention, improving the safety and convenience of the infusion, and avoiding the air input caused by the liquid level below the flow controller after the medicine bag is injected. question.
