Abstract
The invention discloses a kind of safety transfusion needle, comprise tube for transfusion and puncture needle, puncture needle and tube for transfusion junction are provided with transfusion needle fin, tube for transfusion is arranged with security bundle, security bundle is made up of the sleeve pipe and sleeve pipe squeezing handle can accommodating puncture needle, and described sleeve pipe side is provided with the chute mated with transfusion needle fin; Chute is provided with one or more limit convex; Described sleeve pipe squeezing handle is provided with stopper slot, and stopper slot is communicated with chute, is less than the height of transfusion needle fin by sleeve pipe squeezing handle to the length of immediate limit convex.Beneficial effect of the present invention is: 1, structure is simple, structure is exquisite, dexterously stopper slot is opened the squeezing handle place at hard material, and by the restriction of limit convex, makes transfusion needle fin be limited in stopper slot; Safe and reliable.2, the syringe needle polluted, by after closure, has blocked it and has contacted with the direct of the external world, cut off the probability of pricking wound, prevented the employment injuries of nursing staff.
Description
Technical field
The object of the invention is, in order to provide a kind of transfusion needle, to be specially a kind of safety transfusion needle, to belong to technical field of medical instruments.
Background technology
In clinical position, the pricking wound that injection is relevant is random, uncontrollable, and nursing staff is the high risk group that pricking wound occurs.The harm of unsafe injection to society comprise the needle sting after use other people and injection tool use post processing improper cause infecting spread socially.Standard precautions is proposed by the Center for Disease Control nineteen ninety-five, within 1996, implements in the whole America, and China 1999 introduces and within 2000, to enroll in " hospital infection management specification (the trying) " that Ministry of Public Health issues.Whether standard precautions viewpoint is thought: the blood of all patients, body fluid, Excreta, secretions all have infectiousness, no matter have obvious bloodstain to pollute or whether contact the skin mucosa of incomplete property, all need to isolate.Therefore, a large amount of uses of disposable infusion needle will bring the safe disposal problem of disposable infusion needle.
Current normally used safety transfusion needle, comprise tube for transfusion and puncture needle, puncture needle and tube for transfusion junction are provided with transfusion needle fin, tube for transfusion is arranged with security bundle, security bundle is made up of the sleeve pipe and sleeve pipe squeezing handle can accommodating puncture needle, described sleeve pipe side is provided with the chute coordinated with transfusion needle fin, and chute extends to squeezing handle by cannula tip.This safety transfusion needle is after transfusion terminates, and be affectedly bashful handle on the other hand, a hand-held transfusion needle fin, make it relative motion, then transfusion needle fin slips into chute.Chute is provided with limit convex, then puncture needle remaines in sleeve pipe, serves the effect of security protection.
But because chute must make transfusion needle fin slip into smoothly, therefore, sleeve pipe must be elastomeric material.But Just because of this, transfusion needle fin can rock and make chute become loose under external force in sleeve pipe, and then transfusion needle fin departs from limit convex, and transfusion needle fin is deviate from from chute, and safety is unsatisfactory.
Summary of the invention
The object of the invention is to provide a kind of safety transfusion needle, to solve the problems referred to above of prior art.
Object of the present invention can be achieved through the following technical solutions:
A kind of safety transfusion needle, comprise tube for transfusion and puncture needle, puncture needle and tube for transfusion junction are provided with transfusion needle fin, tube for transfusion is arranged with security bundle, security bundle is made up of the sleeve pipe and hard sleeve squeezing handle can accommodating puncture needle, described sleeve side walls is provided with the chute mated with transfusion needle fin; Chute is provided with one or more limit convex; Described sleeve pipe squeezing handle is provided with stopper slot, and stopper slot is communicated with chute, is less than the height of transfusion needle fin by sleeve pipe squeezing handle to the length of immediate limit convex.
For the ease of transfusion needle fin is pushed stopper slot, described cannula tip is designed to inclined-plane, and the minimum point on inclined-plane is the import department of chute.
Described limit convex is provided with three.
Preferred embodiment is the fin height that described stopper slot height equals transfusion needle, and with the hithermost limit convex of sleeve pipe squeezing handle in sleeve pipe and sleeve pipe squeezing handle junction.
Described chute not on the same line, more preferably, described chute wherein one section in arc-shaped.Both prevented puncture needle from sticking up out because of lateral force from chute, transfusion needle fin can be made again to be slipped into stopper slot smoothly.
Because sleeve pipe squeezing handle is hard material, therefore stopper slot can not be loose because of external force, and transfusion needle fin also would not skid off limit convex, thus more safe and reliable.
Beneficial effect of the present invention is: 1, structure is simple, structure is exquisite, dexterously stopper slot is opened the squeezing handle place at hard material, and by the restriction of limit convex, makes transfusion needle fin be limited in stopper slot; Safe and reliable.2, the syringe needle polluted is by after closure, and blocked it and contacted with the direct of the external world, the probability having cut off pricking wound prevents the employment injuries of nursing staff, also alleviates the mental pressure of vast nursery work person's occupational exposure simultaneously.

Fig. 2 is the structural representation of this practical security bundle;
Fig. 3 is the A portion enlarged drawing of Fig. 2;
Fig. 4 is the security bundle structural representation of the embodiment of the present invention;
In figure: 1, tube for transfusion 2, puncture needle 3, transfusion needle fin 4, sleeve pipe 5, sleeve pipe squeezing handle 6, chute 7, limit convex 8, stopper slot.
Detailed description of the invention
Construction features of the present invention is set forth further below in conjunction with accompanying drawing and specific embodiment.
As shown in Figure 1, Figure 2 and Figure 3, a kind of safety transfusion needle, comprise tube for transfusion 1 and puncture needle 2, puncture needle 2 and tube for transfusion 1 junction are provided with transfusion needle fin 3, tube for transfusion 1 is arranged with security bundle, security bundle is made up of the sleeve pipe 4 and hard sleeve squeezing handle 5 can accommodating puncture needle 2, and described sleeve pipe 4 side is provided with the chute 6 mated with transfusion needle fin 3; Chute 6 is provided with one or more limit convex 7; Described sleeve pipe squeezing handle 5 is provided with stopper slot 8, and stopper slot 8 is communicated with chute 6, is less than the height of transfusion needle fin 3 by the length of sleeve pipe squeezing handle 5 to the first limit convexes.
For the ease of transfusion needle fin 3 is pushed stopper slot 8, described sleeve pipe 4 end is designed to inclined-plane, and the minimum point on inclined-plane is the import department of chute 6.
Described limit convex 7 is provided with three.
As seen from Figure 4, described chute 6 not on the same line, more preferably, described chute 6 wherein one section in arc-shaped.Both prevented puncture needle 2 from sticking up out because of lateral force from chute 6, transfusion needle fin 3 can be made again to be slipped into stopper slot 8 smoothly.
Preferred embodiment is that described stopper slot 8 highly equals transfusion needle fin 3 height, and with the hithermost limit convex 7 of sleeve pipe squeezing handle 5 in sleeve pipe 4 and sleeve pipe squeezing handle 5 junction.
Because sleeve pipe squeezing handle 5 is hard material, therefore stopper slot 8 can not be loose because of external force, and transfusion needle fin 3 also would not skid off limit convex 7, thus more safe and reliable.
This safety transfusion needle is after transfusion terminates, and the hand-held transfusion needle fin 3 of a hand-held sleeve pipe squeezing handle 5, make it relative motion, then transfusion needle fin 3 slips into chute 6.
