Abstract
The utility model discloses a rubber plug of a blood collecting tube, which belongs to the field of medical devices. The rubber plug comprises a plug edge and a plug neck, wherein a groove is arranged in the center of the plug edge, an annular boss is arranged at the outer side of the plug neck, and the plug edge and the plug neck adopt an integral structure. The thickness of the rubber plug in the center of the plug edge is reduced by arranging the groove in the center of the plug edge so as to facilitate a syringe needle to puncture, thereby promoting the popularization of the rubber plug of the blood collecting tube. As the annular boss is arranged at the outer side of the rubber plug and the rubber edge and the rubber neck adopt the integral structure, the annular boss can be in tight connection with the groove of the outer wall of the blood collecting tube; therefore, the rubber plug has good air tightness and can maintain the blood collecting tube in a vacuum state for a long term.
Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of rubber plug for vacutainer.
Background technology
At present, rubber plug for vacutainer all is made up of plug edge and plug neck, and plug is along being solid plane, and whole plug is identical along thickness, and when puncturing with pin, very effort has brought inconvenience for the generally popularization of plug.Plug neck outer wall is smooth cylindrical, can not fully contact with the blood taking tube mouth of pipe, and poor air-tightness can not keep being vacuum state in the pipe for a long time.
Summary of the invention
This utility model technical problem to be solved provides a kind of rubber plug for vacutainer, can make things convenient for acupuncture, improves the air-tightness with the blood taking tube mouth of pipe simultaneously.
For solving the problems of the technologies described above, the technical scheme of this utility model is: a kind of rubber plug for vacutainer is provided, comprises plug edge and plug neck, it is characterized in that along central authorities groove being set at plug, at plug neck arranged outside annular boss, the plug edge is an integral structure with the plug neck.
The plug edge all is to be processed by halogenated butyl rubber with the plug neck.
The beneficial effect of this utility model is:
1, this utility model is provided with groove at plug along central authorities, reduces the thickness of plug along central plug, makes things convenient for the syringe needle puncture, promotes the popularization of rubber plug for vacutainer.At plug neck arranged outside annular boss, the plug edge is an integral structure with the plug neck, and annular boss can closely be connected with the groove of blood taking tube outer wall, and air-tightness is good, can keep being in the blood taking tube vacuum state for a long time.
2, plug edge and plug neck all are to be processed by halogenated butyl rubber, and the plug edge and the air-tightness of plug neck are strengthened, and in use, can not deform, and ruggedness is strong.
3, this utility model simplicity of design is easy to use, suitable penetration and promotion and suitability for industrialized production.
Description of drawings
Fig. 1 is the structural representation of this utility model;
Fig. 2 is that the A-A of Fig. 1 is to sketch map.
Among the figure: 1, plug edge; 2, annular boss; 3, plug neck; 4, groove.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is described in further detail.
Like Fig. 1, shown in 2, in this utility model, along 1 central authorities groove 4 is set at plug, reduced the thickness of plug along 1 central plug, make things convenient for the syringe needle puncture.At plug neck 3 arranged outside annular boss 2, plug edge 1 is an integral structure with plug neck 3, and annular boss 2 can closely be connected with the groove of blood taking tube outer wall, and air-tightness is good, can keep being in the blood taking tube vacuum state for a long time.Filling in edge 1 all is to be processed by halogenated butyl rubber with plug neck 3, and the air-tightness of plug edge 1 and plug neck 3 is strengthened, and in use, can not deform, and ruggedness is strong.
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.
