AI Technical Summary

Technical Problem

The external fixation device of the existing hemodialysis tube is prone to squeeze the dialysis tube, resulting in changes in blood flow rate and poor fixation stability, which makes the dialysis tube fall off easily.

Method used

An external fixation device for the hemodialysis tube including a drip bucket, a connecting tube and a fixing mechanism is designed. The fixing mechanism consists of a support block, a connecting rod, a groove block, a baffle plate and a top block. The connecting tube is blocked and fixed by a torsion spring mechanism to ensure the stability of the dialysis tube.

Benefits of technology

Through the use of this device, the problems of unstable fixation of the dialysis tube, easy to fall off and changes in blood flow rate are solved, and the stability and safety of the hemodialysis process are improved.

Abstract

The utility model discloses an in vitro fixing device of hemodialysis tube, which is applied to a dialysis machine, the hemodialysis tube comprises a drip chamber and connecting tubes, the right side of the dialysis machine is provided with the drip chamber, the top end and the bottom end of the drip chamber are both provided with the connecting tubes, the in vitro fixing device of the hemodialysis tube is characterized by further comprising a fixing mechanism, and the right side of the dialysis machine is provided with a baffle. When the in-vitro fixing device for the hemodialysis tube starts to be used, hemodialysis work is carried out on a patient through matched use of a dialysis machine, a drip chamber and a connecting tube, and through use work of a fixing mechanism, the hemodialysis tube is fixed in the use process, and the hemodialysis tube is fixed through the matched use of the structure, so that the hemodialysis tube is more convenient to use. The problems that when an existing dialysis tube fixing device is used, a dialysis tube is not stably fixed and is prone to falling off, and the dialysis tube is prone to being extruded, so that the blood flow speed is changed are solved.
