In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a high isolation nature rubber buffer for special medicine, includes the elastomer, the elastomer includes stopper neck and stopper end, and the stopper neck is located the medicine bottle bottleneck, and the stopper end is located outside the bottleneck, the upper portion of stopper neck is outwards heaved, and the upper portion cover of stopper neck is equipped with halogenated butyl rubber, and the lower extreme diameter of stopper neck is unanimous with medicine bottle bottleneck diameter, the upper surface center department of stopper end is provided with fungi-proofing film, and stopper end upper surface center department is provided with the puncture recess.
As a preferred technical scheme of the utility model, the elastomer is made by thermoplastic elastomer TPE material.
As an optimized technical proposal of the utility model, the lower end of the plug neck is coated with an inert material film.
As the utility model discloses a preferred technical scheme, the inside of stopper neck has the cavity along vertical array, and the cavity is discoid, and the inside chip groove that is provided with of stopper neck between two adjacent cavities.
Compared with the prior art, the beneficial effects of the utility model are that: the rubber plug for the high-isolation special medicine adopts the thermoplastic elastomer TPE material as a main body, has the characteristics of high resilience, high strength, fatigue resistance, no toxicity, temperature resistance and low vulcanization speed of the thermoplastic elastomer, improves the sealing property by matching with a small amount of halogenated butyl rubber material, and reduces the dependence on halogenated butyl rubber.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1 elastomer, 2 halogenated butyl rubber, 3 plugs of necks, 4 plugs of ends, 5 cavities, 6 antibacterial films, 7 chip grooves and 8 puncture grooves.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution: a high isolation special medicine rubber plug, including elastomer 1, elastomer 1 is made of thermoplastic elastomer TPE material, thermoplastic elastomer has high resilience, high strength, fatigue resistance, non-toxicity, temperature resistance and slow vulcanization speed, thermoplastic elastomer folds the puncture hole fast because of its high resilience characteristic after withdrawing the needle, can prevent the weeping effectively, elastomer 1 includes stopper neck 3 and stopper end 4, stopper neck 3 locates in the medicine bottle bottleneck, stopper end 4 locates outside the bottleneck, the upper portion of stopper neck 3 is outwards bulged, squeeze halogenated butyl rubber 2, make the contact of halogenated butyl rubber 2 and medicine bottle bottleneck inner wall tighter, has improved the leakproofness, the upper portion cover of stopper neck 3 is equipped with halogenated butyl rubber 2, a small amount of halogenated butyl rubber 2 can improve the leakproofness of the rubber plug, reduce the dependence to halogenated butyl rubber 2, the lower extreme diameter of stopper neck 3 is unanimous with medicine bottle bottleneck diameter, prevent that halogenated butyl rubber 2 from droing, the lower extreme cladding of stopper neck 3 has the inert material film, the inert material film can prevent liquid medicine and stopper neck 3 contact in the medicine bottle, anti-pollution effectual, there is cavity 5 stopper neck 3's inside along vertical array, cavity 5 is discoid, puncture resistance when cavity 5 is used for reducing syringe needle puncture obturator 1, reduce the puncture degree of difficulty, stopper neck 3 inside between two adjacent cavities 5 is provided with chip groove 7, chip groove 7 is used for holding the piece that the puncture in-process produced, reduce the risk that the piece falls into the medicine bottle, the upper surface center department of stopper end 4 is provided with fungi-proofing film, fungi-proofing film is used for preventing that the syringe needle will be attached to in the bottle is brought into to the bacterium of rubber stopper upper surface in the use, antibacterial effect is good, stopper end 4 upper surface center department is provided with puncture recess 8, puncture recess 4 is used for the puncture position of guide syringe needle.
When in use: the elastic body 1 is made of a thermoplastic elastomer TPE material, the thermoplastic elastomer has the characteristics of high resilience, high strength, fatigue resistance, no toxicity, temperature resistance and low vulcanization speed, the puncture hole can be quickly closed due to the characteristic of high resilience after withdrawing the needle, liquid leakage can be effectively prevented, the sealing property of the rubber plug can be improved by a small amount of halogenated butyl rubber 2, the dependence on the halogenated butyl rubber 2 is reduced, the upper part of the plug neck 3 bulges outwards to extrude the halogenated butyl rubber 2, so that the halogenated butyl rubber 2 is in closer contact with the inner wall of the bottle mouth of the medicine bottle, the sealing property is improved, the liquid medicine in the medicine bottle can be prevented from being in contact with the plug neck 3 by the inert material film, the anti-pollution effect is good, the cavity 5 is used for reducing the puncture resistance when the needle penetrates the filling body 1 and reducing the puncture difficulty, the chip containing groove 7 is used for containing chips generated in the puncture process and reducing the risk of, the antibacterial film is used for preventing bacteria attached to the upper surface of the rubber plug from being brought into the bottle by the needle head in the using process, and the antibacterial effect is good.
