AI Technical Summary

Technical Problem

Traditional dialysis tubing fixing methods are difficult to adapt to different tubing diameters, and the clamping force is not easy to control, which may cause damage or loosening, affecting service life and fluid transfer performance.

Method used

An adjustable fixing device was designed, which includes a binding strap, a rotating structure, a clamping structure, and a protective structure. A rotary motor drives the rotating rod and the connecting rod to control the opening and closing degree of the clamping rod. It is equipped with a protective block and a rubber gasket to protect the dialysis tube.

Benefits of technology

It enables flexible and adaptable clamping of dialysis tubing of different diameters, preventing clamping and wear, ensuring a stable connection of the dialysis tubing, and reducing poor fluid transfer and tubing damage.
