Abstract
The utility model relates to a two-piece type self-destruction injector comprising a push rod, a barrel body and a needle bed, wherein an inner cavity of the needle bed is tightly provided with a self-destruction piece, a through hole is arranged on the needle bed, the self-destruction piece is made from medical polypropylene plastics and comprises a body and a conical self-destruction needle, the body matched with the through hole is provided with a liquid channel, the front end of the push rod is provided with a sealing piece, and a self-destruction slot corresponding to the self-destruction needle is arranged on one surface of the sealing piece. As the inner cavity of the needle bed is tightly provided with the self-destruction piece made from the medical polypropylene plastics, the two-piece type self-destruction injector realizes safe and reliable self destruction and has the advantages of low pollution probability, simple structure and lower cost.
Description
Technical field
This utility model relates to medical instruments field, particularly relates to a kind of two-piece type self-destroyed syringe simple in structure.
Background technology
Fast development along with the modern medical service health service, the conventional syringe of medicine injection develops into diversified disposable use plastic injector at present from glass syringe, push rod is wherein arranged, the three-piece syringe that cylindrical shell and plug are formed, the also two-piece type syringe of forming by push rod and cylindrical shell, the syringe that abandons after using and stop to use for the secondary that prevents syringe in recent years causes once more and pollutes, various type self-destroyed styles have successively also appearred, but all owing to the project organization complexity, the contamination of products probability strengthens, its steady quality performance is relatively poor can't to enlarge use, manufacturing cost is higher in addition, the patient is difficult to bear, multiple for this reason type self-destroyed syringe only limits to design and makes sample, can't industrialization produce in batches.
Be directed to above-mentioned situation, be necessary to provide a kind of self-destroyed syringe in fact, described self-destroyed syringe is not only safe and reliable, and it is low to pollute probability, and simple in structure, and cost is lower, to overcome the defective of self-destroyed syringe in the prior art.
The utility model content
The purpose of this utility model is to provide a kind of two-piece type self-destroyed syringe, and described two-piece type self-destroyed syringe is not only safe and reliable, and it is low to pollute probability, and simple in structure, and cost is lower.
For reaching above-mentioned purpose, this utility model provides a kind of two-piece type self-destroyed syringe, described two-piece type self-destroyed syringe comprises push rod, cylindrical shell and needle stand, wherein, described needle stand inner chamber closely is provided with the self-destruction part, and offer through hole on the described needle stand, cooperate described through hole to offer corresponding logical fluid passage on the self-destruction part, described push rod front end is provided with sealing member.
Especially, described self-destruction part is made for the polypropylene for medical article plastics, and it comprises body, and described body one end is extended with conical self-destruction pin, and described body cooperates the setting of needle stand inner chamber, and described body cooperates through hole to offer logical fluid passage.
Especially, the handle end of described push rod is provided with locating part, and described sealing member offers the self-destruction groove on the one side of corresponding self-destruction pin.
Compared to prior art, this utility model provides a kind of two-piece type self-destroyed syringe, and described two-piece type self-destroyed syringe closely is provided with the self-destruction part of being made by the polypropylene for medical article plastics in the needle stand inner chamber, to realize safe and reliable self-destruction, it is low not only to pollute probability, and simple in structure, and cost is lower.
Description of drawings
With embodiment this utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the profile of this utility model embodiment two-piece type self-destroyed syringe,
Fig. 2 is the profile of this utility model embodiment needle stand,
Fig. 3 is the structural representation of this utility model embodiment self-destruction part.
Among the figure:
1, push rod; 2, cylindrical shell; 3, needle stand; 4, self-destruction part; 5, sealing member; 6, locating part; 30, through hole; 40, body; 41, self-destruction pin; 42, logical fluid passage; 50, self-destruction groove.
The specific embodiment
Please refer to Fig. 1, Fig. 2 and shown in Figure 3, this utility model provides a kind of two-piece type self-destroyed syringe, described two-piece type self-destroyed syringe comprises push rod 1, cylindrical shell 2 and needle stand 3, described needle stand 3 inner chambers closely are provided with self-destruction part 4, described self-destruction part 4 is made for the polypropylene for medical article plastics, identical with the material of cylindrical shell 2, reduced the pollution probability to a great extent, and reduced cost, and described self-destruction part 4 comprises body 40, described body 40 1 ends are extended with conical self-destruction pin 41, described body 40 cooperates needle stand 3 inner chamber settings, and offer through hole 30 on the described needle stand 3, cooperate described through hole 30 on the body 40 of self-destruction part 4, to offer corresponding logical fluid passage 42, so that liquid can suck cylindrical shell 2 smoothly, in addition, described push rod 1 front end is provided with sealing member 5, for easier enforcement self-destruction, in the present embodiment, described sealing member 5 offers self-destruction groove 50 on the one side of corresponding self-destruction pin 41, so that self-destruction pin 41 can penetrate sealing member 5 easily, realize self-destroying function, and the handle end of described push rod 1 is provided with locating part 6, described locating part 6 can be guaranteed the inadvertent destruct of syringe in production and assembly and use, and described limited block 6 is once finished with push rod 1 injection mo(u)lding.
During use, remove locating part 6 behind the extraction medicinal liquid, promote push rod 1 then, then self-destruction pin 41 penetrates sealing member 5 by self-destruction groove 50, to realize self-destruction.
This utility model provides a kind of two-piece type self-destroyed syringe, described two-piece type self-destroyed syringe closely is provided with the self-destruction part of being made by the polypropylene for medical article plastics 4 in needle stand 3 inner chambers, and to realize safe and reliable self-destruction, it is low not only to pollute probability, and simple in structure, cost is lower.
Fig. 1 is the profile of this utility model embodiment two-piece type self-destroyed syringe; but a kind of two-piece type self-destroyed syringe of this utility model is not limited to arrangement mode and this a kind of shape of this a kind of assembly; as shown in Figure 1; satisfying on the basis of its function; can be along with the change of the shape of self-destruction part and change; the change that anyone makes arrangement of components mode of the present utility model, model and shape on principle of the present utility model basis has easily then all fallen into protection domain of the present utility model.
