Description
Technical field
The utility model relates to hemodialysis technology field more particularly to a kind of haemodialysis puncture needles.
Background technique
Haemodialysis is the principle flowed using solute from a highly concentrated side to the low side of concentration, by blood and dialysis
Both solution of liquid introduce the dialyzer with hollowfibre semi-permeable membrance simultaneously, and blood is allowed to be located at the one of hollowfibre semi-permeable membrance
Side, dialyzate are located at the other side of hollowfibre semi-permeable membrance, make the solution of film two sides by disperse and osmosis, to remove people
In in body blood, small molecule toxins, meanwhile, the electrolyte in blood can also reach balance by osmosis, to reach
To the purpose for realizing blood purification.
Currently, connecting human body and dialyzer by haemodialysis puncture needle in haemodialysis.Blood in the prior art
Dialysis puncture needle mainly includes syringe needle, the needle wing, syringe and hollow infusion tube；When puncturing, for those vascular puncture conditions
Bad patient can only select deeper vascular puncture, and after puncturing through, haemodialysis puncture needle is not fixed easily, and only pass through
The mode of the padded needle wing of cotton balls is fixed, and such mode is difficult to control the angle of syringe needle, once pad is excessively high, easily causes
Hemotoncus, and when pulling out needle, cotton balls easily with adhesive tape adhesion, easily causes the drawing of syringe needle to shift, so that injury of blood vessel is caused, by
This, is badly in need of solving.
Utility model content
The purpose of this utility model is that in view of the above-mentioned problems, a kind of haemodialysis puncture needle is provided, to solve existing blood
Liquid dialysis puncture needle is fixed, it is difficult to control syringe needle when puncturing deeper blood vessel by the way of the padded needle wing of cotton balls
Easily is there is the problem of hemotoncus, and is fixed by the way of the padded needle wing of cotton balls in angle, and when pulling out needle, cotton balls is easily and adhesive tape
Adhesion easily causes the drawing of syringe needle to shift, thus the problem of causing injury of blood vessel.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of haemodialysis puncture needle, including syringe needle, the needle wing, syringe and hollow infusion tube, the front end of the syringe with
Syringe needle is fixedly connected, and its rear end is fixedly connected with hollow infusion tube, and the needle wing includes the first alar part being arranged symmetrically and
Two alar parts, first alar part are fixed on syringe, and second alar part is socketed on syringe, and the second alar part can be relative to
The rotation of one alar part.
As a kind of preferred embodiment of the utility model, sleeve joint hole, the hole of the sleeve joint hole are provided on second alar part
Diameter is successively successively decreased by front end to rear end, and the tight lock part matched with the sleeve joint hole of the second alar part is provided on the syringe, described
The radius of tight lock part is successively successively decreased by front end to rear end, and the opening being connected with sleeve joint hole, institute are offered on second alar part
The first alar part is stated to be fixedly connected across the opening with syringe；By using above structure, the spy being simple and convenient to operate with structure
Point, and after the rotation of the second alar part, it can be firmly secured on syringe, not shift.
As a kind of preferred embodiment of the utility model, first alar part, the second alar part upper surface be provided with it is anti-
Sliding line；It is affectedly bashful operation convenient for medical staff, prevents from slipping.
As a kind of preferred embodiment of the utility model, needle cap is socketed on the syringe needle；It can play a protective role, avoid
It accidentally injures.
As a kind of preferred embodiment of the utility model, flow-stopping clip is provided on the hollow infusion tube.
The beneficial effects of the utility model are that a kind of haemodialysis puncture needle structure is simple, is easily achieved, second
Alar part can be rotated relative to the first alar part, and then can adjust the angle between the first alar part, the second alar part as needed, punctured
When deeper blood vessel, the angle between the first alar part, the second alar part is reduced, and then syringe can be raised to be adapted to the puncture of syringe needle
Angle, it is convenient and simple for operation.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of haemodialysis puncture needle of the utility model.
Specific embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.It can manage
Solution, embodiment described herein are used only for explaining the utility model, rather than the restriction to the utility model.
It please refers to shown in Fig. 1, Fig. 1 is a kind of structural schematic diagram of haemodialysis puncture needle of the utility model.
In this present embodiment, a kind of haemodialysis puncture needle, including syringe needle 1, the needle wing, syringe 2 and hollow infusion tube 3,
It is socketed with needle cap 4 on the syringe needle 1, flow-stopping clip 5, the front end of the syringe 2 and syringe needle are provided on the hollow infusion tube 3
1 is fixedly connected, and its rear end is fixedly connected with the front end of hollow infusion tube 3, and the rear end of the hollow infusion tube, which is connected with, to be connect
