Embodiment Construction

[0024] Those of ordinary skill in the art will recognize that the terms "above," "below," "up," "down," "top," "bottom," etc. are used to describe the drawings and do not imply any The scope of the invention is limited by the following claims.

[0025] like Figure 1-9The shown dialysis tube positioning device for nephrology includes a plurality of fixed frames connected by snap connection, which is convenient to flexibly adjust the number of fixed frames used according to the length of different human arms, so that the positioning device can be more reasonably fixed on the arm. The fixing frame is composed of a main card board 1, a left card board 9, a right card board 11, a card block 5, a restraint belt 3, a clip assembly 7 and a winding assembly 8. The main card board 1 has two and is connected with the left card board 9. and the right card board 11 to form a circular structure, which is convenient for fixing a plurality of fixing frames to the arm through the enclosed ci...

Abstract

The present invention relates to the technical field of medical devices, in particular to a dialysis tube positioning device for nephrology, which includes a plurality of clip-connected fixing frames, wherein the fixing frames are composed of a main clip, a left clip, a right clip, and a clip. , tie-down belt, clamping assembly and winding assembly, the main clamping plate has two and forms a circular structure with the left clamping plate and the right clamping plate, and the binding belt runs through the main clamping plate and slides with the main clamping plate connected, the clamping block is clamped on one of the main clamping boards, the clamping block is provided with a clamping slot for clamping the dialysis tube, the two adjacent fixing frames are clamped and connected by clamping components, and the binding The belt runs through the clamping assembly and is fixedly connected with the clamping assembly. The two ends of the binding belt are clamped and connected in the winding assembly to form a structure for adjusting the size of the circular structure surrounded by the fixing frame. The invention realizes the dialysis tube It is firmly fixed on the arm, avoiding the movement of the dialysis tube from affecting the dialysis treatment, and has broad application prospects in the technical field of medical devices.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a dialysis tube positioning device for nephrology. Background technique [0002] Dialysis tubes are usually used to circulate blood during dialysis, especially in hemodialysis treatment. In the existing hemodialysis treatment process, after the needle at the end of the dialysis tube is inserted into the human blood vessel, tape is usually used to seal the dialysis tube. It is fixed on the arm to prevent the dialysis tube from shaking at will, which affects the accurate insertion of the needle at the front end of the dialysis tube into the blood vessels of the human body. When the tube is inserted, the needle punctures the blood vessel, which affects the dialysis treatment and even causes medical accidents. SUMMARY OF THE INVENTION [0003] In order to solve the problem that the existing dialysis tube is only fixed on the arm by tape, which is easy to cause unstable fix...
