Abstract
The utility model relates to a medical appliance, in particular to a medical rubber bottle stopper. The one-sided switching medical rubber bottle stopper of the utility model is structured like that a bottle stopper is provided with a rubber stopper. The rubber stopper is provided with a through hole; the through hole is provided with a valve which can be opened and closed. When in use, the valve is opened up by tension of the injector needle tube and then the liquid medicine is drew out, preventing the rubber mote from pollution generated by the pinhead when is punctured into the bottle stopper.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of medical grade rubber bottle stopper.
Background technology
Existing various medical grade rubber bottle stopper all is incorporate structure, during use will with syringe needle pierce through bottle stopper could extract out the bottle in medicinal liquid.Because syringe needle is a kind of hollow tubular structure, in the process of puncture bottle stopper, have rubber particle inevitably and stop up syringe needle or pollute medicinal liquid, cause allergic reaction, even be detrimental to health.
Summary of the invention
The purpose of this utility model provides a kind of single sided switched formula medical grade rubber bottle stopper that rubber particle pollutes that can not produce.
This utility model is to realize technique scheme like this:
Single sided switched formula medical grade rubber bottle stopper described in the utility model has rubber stopper on the bottle stopper main body, have through hole on the rubber stopper, have in the through hole can deciliter valve.
As to further improvement of the utility model, can on the bottle stopper main body, have an installing hole, rubber stopper is inserted in this installing hole, has anti-skidding projection on the contact surface of rubber stopper and installing hole.
After adopting technique scheme, as long as inject in the through hole of rubber stopper with the syringe needle tube with syringe needle not, exert oneself a little during use, the tension force of syringe needle tube just can strut valve, the medicinal liquid in extracting bottle.Owing to do not need thoroughly to have avoided the pollution of rubber particle to medicinal liquid with the syringe needle bottle closure of rubber that punctures.
Description of drawings
Fig. 1 is the cutaway view of an embodiment of the present utility model;
Fig. 2 is the right view of Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, this utility model is to open an installing hole in the centre of General Purpose Rubber bottle stopper main body 1, rubber stopper 2 is installed in this installing hole, the pipe that rubber stopper 2 is little at the bottom of being one, head is big, inside has valve 4, adopt the medical grade rubber material to make, elasticity is moderate, and valve 4 is enough to when not having the external force effect rubber stopper 2 sealing, is subjected to can opening again tensile the time.
In order to prevent that rubber stopper 2 from skidding off from installing hole, a plurality of anti-skidding projectioies or zigzag projection can be set at the outer surface of rubber stopper 2.
Certainly, rubber stopper 2 also can adopt and bottle stopper main body 1 incorporate structure.
During use, insert rubber stopper 2 with the syringe needle tube that takes off syringe needle, because 2 mouthfuls of big ends of rubber stopper are little, its through hole 3 is enlarged, valve 4 is open, and syringe just can extract the medicinal liquid in the bottle.After syringe left, rubber stopper 2 restored to the original state valve 4 pinch confinement.
