Abstract
The utility model relates to a remaining needle for hemodialysis puncture. The remaining needle mainly comprises an outer catheter component, a heparin cap, an inner needle component and a fixed wing handle and the like. The rear end of a catheter is connected with a catheter fastening clamp, the wing handle is installed on the catheter fastening clamp, a hose is connected to the rear end of the catheter fastening clamp, a catheter clamp is sleeved outside the hose, a circular joint is arranged at the rear end of the hose and connected with an outer screw joint, the outer screw joint is connected with the heparin cap in a screwed manner, an upper needle seat and a blood return device are connected to the rear end of the heparin cap, a needle is inserted into a silica gel stop valve and penetrates into the remaining needle and the hose. The remaining needle for hemodialysis puncture has the advantages of simple structure, convenience in manufacture process, low production cost and the like.
Description
Technical field
This utility model product belongs to medical instruments field, specially refers to a kind of hemodialysis puncture remaining needle of patient in hemodialysis.
Background technology
People injected dialyser with blood collection needle in the past.Annotate back in the patient vessel with syringe again after dialysis, the problem of bringing is thus well imagined, all needs to cut off a radicular arteries when dialysing at every turn, insertion～root glass or metal tube are set up vascular access, when treatment finishes, intubate is pulled out, then the ligation blood vessel, reinsert during next dialysis again.Be limited because human body can utilize blood vessel, the ligation blood vessel, well imagine so repeatedly, and because blood vessel exhausts that being forced to interruption dialyses, thereby dialysis at that time only limits to rescue acute renal failure and poisoning.In hemodialysis, vascular access is the life line of hemodialysis patients, is also new " organ " that the patient depends on for existence.Set up and safeguard that a reliable vascular access is the prerequisite that carries out hemodialysis.At present, yet there are no hemodialysis puncture remaining needle.
Summary of the invention
The technical problems to be solved in the utility model is: above-mentioned the deficiencies in the prior art provide a kind of simple in structure, easy to use, hemodialysis puncture remaining needle.
this utility model is to adopt following technical proposals to realize: comprise the outer catheter assembly, calparine cap, Inner needle tubing assembly, fixed pattern wing handle, feature is: the outer catheter assembly comprises conduit (3), conduit anchorage clip (4), the clamping flexible pipe, control pipe clamp, adapter, at conduit (3) rear end connecting duct anchorage clip (4), wing handle (5) is housed on conduit anchorage clip (4), conduit anchorage clip (4) rear end is connected with flexible pipe (6), flexible pipe (6) outside cover has pipe clamp (7), be provided with in its back-end round splce (8), round splce (8) is connected with external spiral joint (9), external spiral joint (9) is connected with calparine cap internal coiling joint (10) spiral, connect needle stand (13) and blood back device (14) in heparin cap (11) rear end, Inner needle tubing assembly comprises needle tubing (2), needle stand and blood back device, needle tubing (2) was inserted silica gel stop valve (12), in indwelling needle catheter (3) and flexible pipe (6).
The outer flexible tube of this utility model remaining needle is integrally formed, can make blood flow smooth-going, and thrombosis is difficult for forming, and blood flow increases, and reaches better dialysis-effect.Fluorine resin plastic emissary vein puncture wound surface is less, and this is Gospel for artificial blood vessel or arteriovenous fistula, uses remaining needle very general in some developed countries in dialysis.After puncture, steel sleeve pipe nook closing member can be extracted out, and staying in the patient vessel is the pip of soft macromolecule material.Even occuring to slide in blood vessel, the fluorine resin plastic emissary vein can not damage arteriovenous fistula or artificial blood vessel's inwall yet, can be to the blood vessel injury, also avoided traditional puncture needle pin hole to paste the phenomenon that blood vessel wall causes Insufficience of blood flow, in dialysis procedure, the movement of patient body can not cause the unexpected variation of blood flow, does not worry that the syringe needle secondary punctures blood vessel.In first aid, the patient of some restlessnesses is especially applicable.Because of all advantages of the said goods, add good and cheaply, will be accepted by vast dialysis patient.
This utility model is compared with prior art: the adverse consequences that the draw point of can avoiding dialysing uses does not have the risk of piercing blood vessel in dialysis procedure.Its simple structure connects reliably, and is easy to use, has the characteristics of venous detaining needle, is a kind of desirable disposable blood dialysis puncture remaining needle.

The specific embodiment
a kind of hemodialysis puncture remaining needle, comprise the outer catheter assembly, calparine cap, Inner needle tubing assembly, fixed pattern wing handle, feature is: the outer catheter assembly comprises conduit (3), conduit anchorage clip (4), the clamping flexible pipe, control pipe clamp, adapter, at conduit (3) rear end connecting duct anchorage clip (4), wing handle (5) is housed on conduit anchorage clip (4), conduit anchorage clip (4) rear end is connected with flexible pipe (6), flexible pipe (6) outside cover has pipe clamp (7), be provided with in its back-end round splce (8), round splce (8) is connected with external spiral joint (9), external spiral joint (9) is connected with calparine cap internal coiling joint (10) spiral, connect needle stand (13) and blood back device (14) in heparin cap (11) rear end, Inner needle tubing assembly comprises needle tubing (2), needle stand and blood back device, needle tubing (2) was inserted silica gel stop valve (12), in indwelling needle catheter (3) and flexible pipe (6).
Work process is as follows:
The first step punctures.
The second step puncture is completed and is carried out the rollback puncture needle.
The 3rd step treated that needle point rollback to pipe clamp place stepped up pipe clamp.
The 4th step detached puncture needle.
The corresponding dialysis pipeline of the 5th step connection unclamps the flow folder and carries out hemodialysis.
In addition, remaining needle of the present utility model and manufacture method thereof are not limited to above-mentioned example, do not break away from main points of the present utility model and adopt various structures certainly also to be fine.
