Description
Technical field
It the utility model is related to a kind of medicine equipment, more particularly to a kind of blood sedimentation tube blood-sample withdrawal elastic piston.
Background technology
The blood-sample withdrawal elastic piston used at present in various laboratories or analysis room of hospital is held due to its circular configuration
Easily elastic piston is come off from blood sedimentation tube causes to pollute or wastes, certain difficulty is operationally caused to user of service.
Utility model content
The purpose of this utility model is to be directed to above-mentioned present situation, there is provided a kind of to facilitate blood sedimentation tube blood-sample withdrawal elastic piston.
The technical solution adopted in the utility model：A kind of blood sedimentation tube blood-sample withdrawal elastic piston, include hat from top to bottom
Portion and neck, the bizet and the neck are cylinder,
The bizet has the first cavity, and the bottom of first cavity is provided with the annular projection upwardly extended, the ring
Shape is raised to be coaxially disposed with the bizet, and the first groove is formed between the inwall of the annular projection and the bizet；
The neck has the second cavity, and the inner wall edge of the lower end of the neck has inclined-plane, makes second cavity
Lower end form the perforate of frustoconical, and length direction of the diameter of the perforate along the neck is gradually reduced, described the
The top of two cavitys upwardly extends to form the 3rd cavity along edge, and the top of the 3rd cavity is under first cavity
Side.
The beneficial effects of the utility model are：By setting the first groove, increase the friction of elastic piston and heparin tube
Power, elastic piston is set to be not easy to come off from heparin tube；Further, glass-tube or modeling pipe are inserted in the second cavity, after insertion, is passed through
Groove connection, fixed glass-tube or modeling pipe, complete sealing glass-tube or mould the process of pipe.
Brief description of the drawings
Involved accompanying drawing is simply introduced in being described to the embodiment of the present invention, in order to in the embodiment of the present invention
Technical scheme become apparent from, completely illustrated, following accompanying drawing is only for some embodiments of the present invention, not limiting
The system present invention, on the premise of without other creative works, it is clear that other accompanying drawings can be obtained according to these accompanying drawings.
Fig. 1 is a kind of sectional view of blood sedimentation tube blood-sample withdrawal elastic piston.
Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit the scope of the utility model.
As shown in figure 1, a kind of blood sedimentation tube blood-sample withdrawal elastic piston provided by the utility model, includes hat from top to bottom
Portion 10 and neck 11, wherein, bizet 10 and neck 11 are cylinder, and bizet 10 and neck 11 have the first cavity and second respectively
Cavity 110.The bottom of first cavity is provided with the annular projection 12 upwardly extended, and annular projection 12 and bizet 10 are coaxial, ring-type
The first groove 20 is formed between projection 12 and the inwall of bizet 10.The inner wall edge of the lower end of neck 11 has inclined-plane, makes the second sky
The lower end of chamber 110 forms the perforate 13 of frustoconical, and length direction of the diameter of perforate 13 along neck 11 is gradually reduced, and second
The top of cavity 110 upwardly extends to form the 3rd cavity 111 along edge, and the top of the 3rd cavity 111 is in the first cavity 100
Lower section.
Further, the external diameter of bizet 10 is more than the external diameter of neck 11.
Further, 1/2 of the depth of the first cavity 110 no more than the height of bizet 10.
Further, the top of the 3rd cavity 111 tilts to axis direction extends a distance into and forms hook and slot 112.
Whole elastic piston is one-shot forming, it is not necessary to adhesion in addition.
In use, the first groove 20 formed between annular protrusion 12 and bizet 10 is used to connect modeling cap, make the elastomer
The frictional force of piston and heparin tube increases, and makes elastic piston be not easy to come off from heparin tube；Further, the conical convenience of perforate 13
Glass-tube or modeling pipe are inserted in second cavity 110, after insertion, connected by groove 112, fix glass-tube or modeling pipe, complete sealing glass
The process of pipe or modeling pipe.
In summary, the utility model increases the frictional force of elastic piston and heparin tube, made by setting the first groove
Elastic piston is not easy to come off from heparin tube；Further, glass-tube or modeling pipe are inserted in the second cavity, after insertion, passes through groove
Connection, fixed glass-tube or modeling pipe, complete sealing glass-tube or mould the process of pipe.
Preferred embodiment of the present utility model is these are only, it is all in the utility model not to limit the utility model
Spirit and principle within, any modification, equivalent substitution and improvements made etc., should be included in protection model of the present utility model
Within enclosing.
