Abstract
The utility model discloses a medical rubber stopper, which belongs to the field of rubber stoppers. The medical rubber stopper comprises a rubber stopper body and is characterized in that the rubber stopper body is of a silicon rubber integrated structure, and a brominated butyl rubber layer is compounded on the outer surface of the rubber stopper body in a vulcanization manner. The medical rubber stopper has better self-sealing property and low absorbency to medicines or water because brominated butyl rubber has high cleanness and chemical resistance as well as low permeability to air, various gases and moisture. Experiments prove that the brominated butyl rubber stopper has lower medicine turbidity and higher sealing property in comparison with the common butyl rubber stopper, thus due to the use of the brominated butyl rubber, the sealing property of the rubber stopper is improved; and because the rubber stopper body is made from silicon rubber, thus the production cost of the medical rubber stopper is reduced.
Description
Technical field
This utility model belongs to the plug field, is specifically related to a kind of medical rubber stopper.
Background technology
Used medical rubber stopper is the overall structure of homogeneity at present, and from safety and other comprehensive consideration of drug packaging, plug adopts silicone rubber or butyl rubber to make basic material mostly; But silicone rubber is because its special microstructure causes its breathability better, in other words; Just its sealing property is relatively poor, can not satisfy the demand of drug packaging, so select butyl rubber at present mostly for use; The butyl rubber production technology of China is still immature, and used butyl rubber mainly relies on import, costs an arm and a leg; Strengthen the production cost of plug, shifted the sealing and the economy of plug onto be difficult to be in harmonious proportion opposite.
Summary of the invention
This utility model technical problem to be solved provides a kind of medical rubber stopper, can improve its sealing property, practices thrift its production cost again.
For solving the problems of the technologies described above; The technical scheme of this utility model is: a kind of medical rubber stopper is provided; Comprise rubber plug body, it is characterized in that: said rubber plug body is the integral structure of silicone rubber, and the outer surface sulfuration of rubber plug body is compounded with the butyl rubber bromide glue-line.
Have shrinkage pool on the roof of rubber plug body.
The roof of rubber plug body is provided with bulge loop, and bulge loop is positioned at the periphery of shrinkage pool.
The beneficial effect of this utility model is:
1, because brombutyl has abrasive property and chemical resistance; And to the hypotonicity of air, all gases and dampness; Make it have good self sealss property and to the low absorbability of medicine or water; Experiment showed, that brominated butyl rubber plug has lower medicine turbidity and the sealing of Geng Gao than common butyl rubber plug, so the use of brombutyl has improved the sealing property of plug; Because rubber plug body is selected silicone rubber for use, has reduced its production cost.
2, owing to have shrinkage pool on the roof of rubber plug body, reduce the puncture thickness of syringe needle, used more conveniently, strengthened the self sealss performance of pin hole simultaneously.
3, contact by the face face between the roof that can make plug of the bulge loop on the plug roof and production line and change the contact of line face into, plug is taken off from production line more easily, thereby improved production efficiency.
Description of drawings
Fig. 1 is the structural representation of this utility model;
Fig. 2 is that the A of Fig. 1 is to view;
Among the figure: 1, rubber plug body, 2, the butyl rubber bromide glue-line, 3, shrinkage pool, 4, bulge loop.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is described in further detail.
As shown in the figure; The rubber plug body 1 of this utility model is the overall structure of silicone rubber; The outer surface sulfuration of rubber plug body 1 is compounded with brominated butyl rubber plug layer 2, and brominated butyl rubber plug has lower medicine turbidity and the sealing of Geng Gao than common butyl rubber plug, thereby has improved the sealing property of plug; Simultaneously, because rubber plug body 1 is selected silicone rubber for use, reduced its production cost.Have shrinkage pool 3 on the roof of rubber plug body 1, reduced the puncture thickness of syringe needle, use more conveniently, strengthened the self sealss performance of pin hole simultaneously.The roof of rubber plug body 1 is provided with bulge loop 4, and bulge loop 4 is positioned at the periphery of shrinkage pool 3, is contacted by the face face between the roof that makes plug and production line and changes the contact of line face into, and plug is taken off from production line more easily.
It is to be noted; Above-mentioned embodiment only is this utility model preferred embodiment; For those skilled in the art, under the prerequisite that meets this utility model operation principle, any be equal to or similar replacement all falls in the protection domain of this utility model.
