[0005] The utility model provides the following technical scheme: a fixing device for nephrology hemodialysis tube, including rubber seat, the inside of rubber seat is provided with fixed structure, the fixed structure includes fixed groove and two rotating holes, the inside fixed mounting of fixed groove has three fixed seats, three the inside rotation of fixed seat is installed with rail, the inside rotation of left rotating hole is installed with threaded rod, the top of threaded rod is fixedly installed with steering handle, the outer surface of threaded rod is screw mounted with screw block, the inside fixed mounting of right rotating hole is installed with limit rod, the outer surface of limit rod is slidably installed with another screw block, the bottom of two screw blocks is fixedly installed with pressing plate, the top of pressing plate is fixedly installed with note frame.

[0006] As a preferred technical scheme of the utility model, the outer surface bottom of the rubber seat is fixedly installed with a soft pad, and the soft pad is fixed to the bottom of the rubber seat by a third magic tape.

[0007] As a preferred technical scheme of the utility model, the outer surface of the rubber seat is hingedly installed with an elastic band on both sides.

[0008] As a preferred embodiment of this utility model, a first Velcro closure is sewn onto the inner side of the outer surface of the elastic band on the right.

[0009] As a preferred embodiment of this utility model, a second Velcro closure is sewn onto the outer surface of the elastic band on the right.

[0010] As a preferred technical solution of this utility model, a groove is provided at one end of the outer surface of the elastic band on the right side.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This is a fixing device for hemodialysis tubing in nephrology. Through a fixing structure, when fixing the dialysis tubing, rotating the handle causes the threaded rod to rotate and the two threaded blocks to drive the pressure plate to move upward and horizontally. Then, rotating the rotating rail causes it to rotate into the interior of the fixing seat. At this time, the dialysis tubing can be placed on top of the fixing seat. Then, the rotating rail is unscrewed from the fixing seat, so that the fixing seat and the rotating rail form a closed circular groove, thereby fixing the dialysis tubing. Then, rotating the handle again causes the threaded rod to rotate, causing the threaded blocks to drive the pressure plate to move downward and press the rotating rail, thereby further fixing the dialysis tubing. This achieves the purpose of fixing the dialysis tubing and preventing accidental dislodgement. Attached Figure Description
