Abstract
The utility model provides an infusion device needle head which comprises a needle head body. A needle point is arranged at one end of the needle head body. A needle handle and an infusion tube are connected with the other end of the needle head body. The infusion device needle head is characterized by further comprising a needle head protective sleeve, wherein the needle head body is wrapped up in the needle head protective sleeve. A through hole is formed at one end of the needle head protective sleeve and the needle head body can be allowed to penetrate through the through hole. A groove is formed in the needle head protective sleeve, and the needle handle penetrates through the groove and is fixedly connected with the needle head body. The infusion device needle head is stretched out when used and retracted after used. Therefore, the possibility that medical workers are punctured by the exposed needle head and blood infection is caused can be avoided, and the infusion device needle head is reasonable in design, simple in structure and convenient to use.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically, relates to a kind of syringe needle for transfusion device.
Background technology
Infusion treatment is clinical the most a kind of therapeutic modality of normal use.Transfusion needs to use transfusion device, is connected with syringe needle for transfusion device on the transfusion device, by syringe needle for transfusion device puncture venous patient, realizes transfusion.The syringe needle for transfusion device that uses comprises spike body, needle handle and tube for transfusion at present, before syringe needle for transfusion device uses, is overlapping the protective sleeve of a tubular on the spike body, in use, protective sleeve is taken off, and syringe needle has just exposed out.After but transfusion is finished clinically, syringe needle with regard to the protection that lost protective sleeve and exposed outside, medical personnel are often arranged by exhausted needle sting.This has increased the possibility that infect in medical personnel's blood source greatly.
The utility model content
The purpose of this utility model is to overcome the weak point of above-mentioned conventional art, provides and still can protect syringe needle after a kind of use, prevents the syringe needle for transfusion device that needle point is exposed.
The purpose of this utility model reaches by following technical measures:
A kind of syringe needle for transfusion device; comprise spike body; one end of described spike body has needle point; the other end of described spike body is connected with needle handle and tube for transfusion; it is characterized in that: also comprise the protective sleeve of syringe needle that wraps up spike body; one end of described protective sleeve of syringe needle is provided with the through hole that can allow spike body to pass through, and described Tip protection puts and is provided with groove, and described needle handle passes groove fixedlys connected with spike body.Untapped spike body is in the protective sleeve of syringe needle, during use, grips needle handle spike body is released in protective sleeve of syringe needle, just can use as the general infusion set syringe needle; After transfusion finishes, grip needle handle spike body is return in the protective sleeve of syringe needle, just can prevent the exposed accidental injury that causes of exhausted syringe needle, thus the possibility of avoiding the blood source to infect.
The both sides of described groove are provided with to the midline outstanding protuberance relatively, and the distance between the described relative protuberance is less than the thickness of needle handle.The protuberance that is oppositely arranged can retrain needle handle, prevents that spike body is free to slide.
Described protuberance has two groups, and described two groups of protuberances are positioned at the two ends of groove respectively.
The offside that described Tip protection puts groove is provided with flaky fixed-wing.Fixed-wing is convenient to be reinstated protective sleeve of syringe needle and needle handle one on the patient skin of immobilization with adhesive tape.
Described fixed-wing is positioned at the end that Tip protection is arranged with through hole.
Owing to adopted technique scheme, compared with prior art, the utility model has the advantages that:
This utility model provides a kind of syringe needle for transfusion device, syringe needle is stretched out, and after finishing using, syringe needle is regained, thereby the possibility that can avoid the medical worker to be caused the blood source to be infected by exposed needle sting, it is reasonable in design, simple in structure, easy to use.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Accompanying drawing 1 is the structural representation of a kind of syringe needle for transfusion device of this utility model;
Accompanying drawing 2 be in the accompanying drawing 1 A to view;
Accompanying drawing 3 is structural representations of a kind of syringe needle for transfusion device of this utility model.
The specific embodiment
Embodiment: as accompanying drawing 1 to shown in the accompanying drawing 3; a kind of syringe needle for transfusion device; comprise spike body 7; one end of spike body 7 has needle point 8; the other end of spike body 7 is connected with needle handle 4 and tube for transfusion 1, is enclosed with protective sleeve of syringe needle 2 on the spike body 7, and an end of protective sleeve of syringe needle 2 is provided with the through hole 9 that can allow spike body 7 to pass through; protective sleeve of syringe needle 2 is provided with groove 6, and needle handle 4 passes groove 6 fixedlys connected with spike body 7.
As shown in Figure 2, the both sides of groove 6 are provided with outstanding to the midline protuberance 5 relatively, and the distance between the relative protuberance 5 is less than the thickness of needle handle.The protuberance 5 that is oppositely arranged can retrain needle handle 4, prevents that spike body 7 is free to slide.
As shown in Figure 2, protuberance 5 has two groups, and two groups of protuberances 5 lay respectively at the two ends of groove 6.
Shown in accompanying drawing 1 and accompanying drawing 3, the offside of groove 6 is provided with flaky fixed-wing 3 on the protective sleeve of syringe needle 4.Fixed-wing 3 is conveniently reinstated protective sleeve of syringe needle 2 and needle handle 4 one on the patient skin of immobilization with adhesive tape.
As shown in Figure 3, fixed-wing 3 is positioned at the end that protective sleeve of syringe needle 2 is provided with through hole 9.
Using method: untapped spike body 7 is in the protective sleeve of syringe needle 2; During use, grip needle handle 4 spike body 7 is released in protective sleeve of syringe needle 2, just can use as the general infusion set syringe needle; After transfusion finishes, grip needle handle 4 spike body 7 is return in the protective sleeve of syringe needle 2, just can prevent the exposed accidental injury that causes of exhausted syringe needle, thus the possibility of avoiding the blood source to infect.
