AI Technical Summary
The lack of visualization capabilities in deep vein catheterization increases the risk of misoperation, fluid path confusion, and complications, affecting treatment efficacy and safety.
A visual fluid circuit protection device was designed, which includes an infusion mechanism, a monitoring mechanism, and a display mechanism. The monitoring component monitors the fluid circuit status in real time and displays the information on the display screen to ensure the smooth flow of the fluid circuit and the accurate positioning of the catheter.
It effectively reduces the risk of fluid circuit confusion and complications, improves the efficiency and safety of infusion operations, and provides reliable clinical treatment support.
