Abstract
The utility model relates to a medical instrument for transfusion, in particular to an injection part with a guide slot, which comprises a tee joint of the injection part and a rubber stopper of the injection part arranged on the tee joint, wherein the tee joint of the injection part is provided with a narrowing structure. The injection part is characterized in that the rubber stopper is provided with the guide slot matching with the narrowing structure. The utility model has simple structure, easy implementation and difficult displacement of a puncture needle during dosing.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments that is used to infuse, and specifically is a kind of injection member of tape guide groove.
Background technology
Injection member is parts on the transfusion apparatus, is used in the infusion process dosing, is mainly used in transfusion apparatuses such as disposable infusion set, disposable use venous detaining needle, calparine cap.Injection member generally includes injection member threeway and injection member plug, wherein the injection member plug is made with rubber, and it need add certain quantity of additive in process of production, in rubber and medicinal liquid contact process, these additives meeting slow release pollute medicinal liquid in medicinal liquid.Therefore, the contact area of injection member plug and medicinal liquid is the smaller the better.The contact area method commonly used that reduces injection member plug and medicinal liquid is with the bore minimizing of injection member threeway, is commonly called as " closing in ".When dosing, cause the syringe needle skew easily but close up, make the dosing failure.
Summary of the invention
This utility model provides a kind of injection member of tape guide groove at the weak point in the prior art, and it is easy to generate the shortcoming of skew in the time of can overcoming the medicated pillow dosing.
The following technical scheme of the concrete employing of this utility model:
A kind of injection member of tape guide groove comprises the injection member threeway and is arranged on injection member plug in the threeway that the injection member threeway has the closing in structure, it is characterized in that, has the gathering sill with the coupling that closes up on the described plug.
Described injection member is used for infusion set.
The utility model has the advantages that:
1) because gathering sill is set, is not easy to produce skew when making the syringe needle puncture;
2) this utility model is simple in structure, implements easily;
3) owing to the existence of gathering sill, the closing in of threeway can be done forr a short time, so just can make medicinal liquid and plug contact area littler, has reduced the risk that plug pollutes.
Description of drawings
Fig. 1 is the infusion set structural representation;
Fig. 2 is Figure 1A portion enlarged diagram;
Fig. 3 is the injection member structural representation that do not close up;
Fig. 4 is a closing in injection member structural representation;
Fig. 5 is an injection member structural representation of the present utility model.
The specific embodiment
Further set forth this utility model below in conjunction with accompanying drawing.
As shown in Figure 1, on infusion set 1, comprise medical filtration device 2, before medical filtration device 2, be provided with injection member, be used for the infusion process dosing.
As shown in Figure 2, injection member comprises injection member threeway 4 and injection member plug 3, and injection member herb liquid 5 directly contacts injection member plug 3.
As shown in Figure 3, when injection member did not close up, puncture needle 6 punctured easily, but the contact area of medicinal liquid and plug 3 is big, and medicinal liquid is contaminated to have a big risk.
As shown in Figure 4, injection member threeway 4 has closing in structure 7, and this moment, medicinal liquid and plug 3 contacts area were little, but is offset easily during lancet puncture.
As shown in Figure 5, injection member of the present utility model is having gathering sill 8 on plug 3 on Fig. 4 basis, and puncture needle 6 can not produce the medicated pillow skew along gathering sill 8 punctures.Therefore, closing in structure 7 can be done forr a short time, further reduces the contaminated risk of medicinal liquid.
Claims (1)
1. the injection member of a tape guide groove comprises the injection member threeway and is arranged on injection member plug in the threeway that the injection member threeway has the closing in structure, it is characterized in that, has the gathering sill with the coupling that closes up on the described plug.
