Description

Novel hemodialysis catheter

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to novel hemodialysis pipe.

Background

Dialysis refers to the movement of solutes from a highly concentrated solution to a less concentrated solution through a semi-permeable membrane. Hemodialysis involves the movement of solutes and the movement of water, i.e., the contact of blood and dialysate by a semipermeable membrane and the exchange of substances by concentration gradient in the artificial kidney of the dialyzer, so that metabolic wastes and excess electrolytes in the blood move to the dialysate, and calcium ions, bases and the like in the dialysate move to the blood. Hemodialysis is one of the safer, easy-to-use and widely-applied blood purification methods.

Currently, in acute hemodialysis treatment, doctors often guide blood of human bodies into dialyzers through hemodialysis catheters, and the blood is filtered and then returned to blood vessels through pipelines. Because the extension tube of the existing dialysis catheter is made of PU material, the flexibility is poor. When being connected with the dialyzer, the joint of the extension tube and the connecting seat is easy to bend, thereby causing the blockage of the pipeline and even causing the thrombus. Therefore, a clinical anti-rupture hemodialysis catheter is urgently needed.

In order to solve the above technical problem and achieve the above technical effect, the utility model discloses a following technical content realizes:

a novel hemodialysis catheter comprises a catheter main body, a fixing clamp, a triangular connecting seat with three interfaces, a first extension tube, a second extension tube, a first hemostatic clamp, a second hemostatic clamp, a first luer connector and a second luer connector, wherein the catheter main body is connected to one interface of the triangular connecting seat through the fixing clamp; the first hemostatic clamp and the second hemostatic clamp are respectively sleeved on the first extension tube and the second extension tube, and the first extension tube and the second extension tube are respectively communicated with the other two interfaces of the triangular connecting seat; the first Ruhr joint and the second Ruhr joint are respectively sleeved at the tail ends of the first extension pipe and the second extension pipe, which are far away from the triangular connecting seat, sleeves are arranged at the joints of the first extension pipe, the second extension pipe and the triangular connecting seat, the first extension pipe and the second extension pipe penetrate through the interiors of the sleeves to be communicated with the triangular connecting seat, and soft springs are respectively arranged among the first extension pipe, the second extension pipe and the sleeves.

Furthermore, the soft spring is sleeved on the first extension pipe and the second extension pipe respectively.

Further, the sleeve is a silica gel hose.

The utility model has the advantages that:

through setting up sleeve pipe, soft spring, can first extension pipe, second extension pipe when using change with the triangle connecting seat angle, make the junction of first extension pipe, second extension pipe and triangle connecting seat become the arc under the support of soft spring, can supply blood normal circulation, avoid taking place to buckle, cause the pipeline not to lead to the fact the thrombus.

Of course, it is not necessary for any product in which the invention is practiced to achieve all of the above-described advantages at the same time.
