Safety, the most economic and most long vascular access of holding time.
Essential medicine equipment in when internal-fistula needle is hemodialysis, it mainly punctures needle tubing, pin by stainless steel
The wing, body, vessel clamp, joint etc. are constituted.In hemodialysis, by puncturing patient's arteriovenous internal fistula, and with following in vitro
Endless tube road and dialyzer connection, form the extracorporal circulatory system path of blood.It is typically once dialysed（About 4 hours time）Complete
Afterwards, it is unplugged and abandons and uses.So so that the drawbacks of existing internal-fistula needle has larger：After internal fistula puncture needle has been used,
Needle point is directly exposed outside.The exposed needle point of patient blood was contacted, often to medical personnel and waste treatment people
Member damages, and triggers the infection and propagation of blood borne disease.
Utility model content
The technical problems to be solved in the utility model is：One kind is provided and overcomes above-mentioned deficiency, internal-fistula needle needle point can be carried out
The safe internal-fistula needle of protection.
The solution that the utility model solves its technical problem is：A kind of safety-type internal fistula puncture needle, includes needle stand,
Sheath, the sheath includes through hole, and the needle stand can pass through described through hole, and the periphery two ends of the sheath are solid provided with two
Determine the wing, the front end face of the needle stand, which is provided with mounting hole, the mounting hole, is fixed with puncture needle, and the front of the needle stand is with after
The first neck and the second neck are respectively equipped with side, the distance between first neck and the second neck is not less than puncture needle
Length；The rear end of the sheath sets also one movable button and Button Block, and left end and the Button Block of the movable button be hinged, movable button
Right-hand member is snapped connection with Button Block；The inner surface of the movable button is provided with fixture block, the fixture block and the first neck or the second neck
Connection.
As the further improvement of above-mentioned technical proposal, the through-hole wall is provided with guiding groove, and the needle stand is provided with
Rib is oriented to, the guiding rib is connected with guiding groove.
As the further improvement of above-mentioned technical proposal, first neck and the second neck, which are located at, to be oriented on rib.
As the further improvement of above-mentioned technical proposal, the fixed-wing is provided with a circular port.
The beneficial effects of the utility model are：Piercing needle can be recovered to inside sheath by puncture needle after use,
To prevent from damaging medical personnel or waste treatment personnel.
Brief description of the drawings
, below will be to needed for embodiment description in order to illustrate more clearly of the technical scheme in the utility model embodiment
The accompanying drawing to be used is briefly described.Obviously, described accompanying drawing is a part of embodiment of the present utility model, rather than entirely
Portion's embodiment, those skilled in the art on the premise of not paying creative work, can also obtain it according to these accompanying drawings

Fig. 1 is structural representation of the present utility model；
Fig. 2 is use state one of the present utility model；
Fig. 3 is use shape body two of the present utility model.
Embodiment
The technique effect of design of the present utility model, concrete structure and generation is carried out below with reference to embodiment and accompanying drawing
Clearly and completely describe, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is a part of embodiment of the present utility model, rather than whole embodiments, based on embodiment of the present utility model, the skill of this area
The other embodiment that art personnel are obtained on the premise of not paying creative work, belongs to the model of the utility model protection
Enclose.In addition, all connection/annexations being previously mentioned in text, not singly refer to component and directly connect, and refer to can be according to specific reality
Situation is applied, by adding or reducing couple auxiliary, to constitute more excellent draw bail.Each technology in the invention is special
Levy, can be with combination of interactions on the premise of not conflicting conflict.
A kind of reference picture 1, safety-type internal fistula puncture needle includes needle stand 1, and sheath 2, the sheath 2 includes through hole 21,
The needle stand 1 can pass through described through hole 21, and the periphery two ends of the sheath 2 are provided with before two fixed-wings 22, the needle stand 1
End face is provided with to be fixed with puncture needle, the front and rear of the needle stand 1 on mounting hole 11, the mounting hole 11 and is respectively equipped with
Distance between first neck 12 and the second neck 13, the neck 13 of the first neck 12 and second is not less than the length of puncture needle；
The rear end of the sheath 2 sets also one movable button 23 and Button Block 24, and left end and the Button Block 24 of the movable button 23 are hinged, activity
