Description
Technical field
This utility model relates to a kind of safe infusion pin.
Background technology
For fear of cross infection occurring; The intravenous injection and transfusion pin of medical institutions has all adopted disposable mode now; For used transfusion needle,, cause the secondary cross infection in order to prevent needle sting people in carrying out garbage disposal or recycling process; All can enclose safety protective cover on the existing venoclysis needle used transfusion needle is protected, like the safe infusion pin.Existing safe infusion pin generally includes transfusion needle assembly, transfusion needle protective jacket and containment, and the transfusion needle assembly comprises a needle holder and be installed in the needle tubing on the needle holder that the needle holder both sides are provided with the fin that symmetry is stretched out; Protective jacket is enclosed within on the needle tubing before using, containment integral body in tubular construction, the transfusion needle assembly is arranged in the containment together with the protective jacket matched in clearance; The both sides of containment are provided with axial slide; Said needle holder two side tabs are exposed from chute, and the end of chute is provided with the locked groove of positioning tabs, and location structure is normally at the latter end of chute; Chute narrows down; Less than the thickness of positioning tabs, in the end of chute and locked groove junction shoulder rank are set and prevent the positioning tabs back skating, reach localized purpose.But because containment all is to be made by plastic material usually, chute is also long, so the latter end of chute has certain elasticity, might cause the positioning tabs back skating, has unsafe factor.
Summary of the invention
The purpose of this utility model is for the deficiency that overcomes prior art a kind of safer safe infusion pin to be provided.
To achieve these goals, the technical scheme of this utility model employing is: a kind of safe infusion pin comprises transfusion needle assembly and containment; The transfusion needle assembly comprises a needle holder and is installed in the needle tubing on the needle holder; The needle holder both sides are provided with the fin that symmetry is stretched out, containment integral body in tubular construction, the transfusion needle pack clearance is equipped with in containment; The both sides of containment are provided with axial slide; Said needle holder two side tabs are exposed from chute, and the end of chute is provided with the locked groove of positioning tabs, it is characterized in that: said needle holder is provided with safe projection; Be provided with the projection guide groove with the projection matched in clearance with the corresponding position of safety projection sliding trajectory on the said containment; Safe projection is in the projection guide groove, and the end of projection guide groove is provided with the slotted eye that matches with safe projection shape mutually and constitutes safety groove, and the latter end narrowed width of projection guide groove is less than the safety bump width.
Compared with prior art, this utility model is owing to also be provided with safe projection on needle holder, and said containment is provided with projection guide groove and safety groove, is equivalent to be provided with a locking mechanism again in different positions, therefore increased reliability more.
Further setting as this utility model; The latter end width of said projection guide groove narrows to form wedge shape gradually; Said safe projection is wedge shape towards an end of containment afterbody, and the other end is the wedge shape concave surface, and said safety groove matches near the wedge shape concave surface of projection guide groove one side shape and safe projection.Said safe projection one end is wedge shape and makes things convenient for the transfusion needle assembly to slide backward, and the other end is the wedge shape concave surface can further improve the reliability of locking.
As further being provided with again of this utility model; Under said transfusion needle components containing state; Be provided with the piece that supports of projection on the said containment on the opposite side inwall relative with the projection guide groove with the corresponding position of said needle holder, said to support piece be the inclined-plane towards containment front end one side.Be provided with projection support piece after; After the safe infusion pin used, said transfusion needle components containing was to containment the time, and supporting piece can be with pushing up on the said needle holder; Make said safe projection more be difficult for from the projection guide groove, deviating from, further improve the reliability of locking.
To combine accompanying drawing and specific embodiment that this utility model is further described below.
