Abstract
It the utility model is related to a kind of upper die mould blood-sample withdrawal elastic piston, including yielding movable cock body, yielding movable cock body includes cock cap, plug neck and plug tongue from top to bottom, the diameter of plug neck is respectively less than cock cap and fills in the diameter of tongue, cock cap is close to one end circumference for filling in neck, outstanding formation flange, flange forms the bizet of frustoconical to the top extension certain distance of cock cap, and the base diameter of bizet is less than its top diameter, flat surface, the circumferentially spaced double wedge provided with radial direction in upper surface of flat surface are formed on the top of bizet.The utility model in the outside of cock cap by being provided with bizet, elastic piston can be made to meet the basic function requirement of sealing, and it is not easy to come off from heparin tube, with the anti-function raised one's hat, so as to avoid polluting and waste, used especially suitable for laboratory and hospital's blood analysis room, be provided with double wedge in the flat surface of bizet in addition, facilitate rotation to take.
Description
Technical field
It the utility model is related to a kind of medicine equipment, more particularly to a kind of upper die mould 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 heparin 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 die mould blood-sample withdrawal elastic piston in a kind of convenience.
The technical solution adopted in the utility model：A kind of upper die mould blood-sample withdrawal elastic piston, including yielding movable cock body,
The yielding movable cock body includes cock cap, plug neck and plug tongue from top to bottom, and the diameter of the plug neck is respectively less than the cock cap and described
Fill in the diameter of tongue, the cock cap is close to one end of the plug neck is circumferential, outstanding formation flange, and the flange is to the cock cap
Top extension certain distance form the bizet of frustoconical, and the base diameter of the bizet is less than its top diameter,
Flat surface, the circumferentially spaced double wedge provided with radial direction in upper surface of the flat surface are formed on the top of the bizet.
The beneficial effects of the utility model are：By being provided with bizet in the outside of cock cap, it can meet elastic piston close
The basic function requirement of envelope, and be not easy to come off from heparin tube, there is the anti-function raised one's hat, so as to avoid polluting and waste,
Used especially suitable for laboratory and hospital's blood analysis room, be provided with double wedge in the flat surface of bizet in addition, facilitate rotation to take,
In summary, the utility model is simple in construction, easy to use.
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 structural representation of upper die mould 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.
Such as Fig. 1, a kind of upper die mould blood-sample withdrawal elastic piston provided by the utility model, including yielding movable cock body 1, bullet
Property piston body 1 from top to bottom include cock cap 10, plug neck 11 and plug tongue 12, wherein, plug neck 11 diameter be respectively less than cock cap 10 and plug
The diameter of tongue 12, cock cap 10 is close to one end of plug neck 11 is circumferential, outstanding formation flange 100, and flange 100 is to the top of cock cap 10
Portion's extension certain distance forms the bizet 13 of frustoconical, and the diameter of the bottom of bizet 13 is less than the diameter at the top of it.Bizet 13
Top formed flat surface A, the flat surface A circumferentially spaced double wedge 14 provided with radial direction in upper surface.
Preferably, the height of double wedge 14 is higher than the upper surface of cock cap 10.
The flange 100 and yielding movable cock body 1 of the present embodiment are molded successively in forming process, it is not necessary to adhesion in addition.
The present embodiment can make elastic piston meet that the basic function of sealing will by being provided with bizet in the outside of cock cap
Ask, and be not easy to come off from heparin tube, there is the anti-function raised one's hat, so as to avoid polluting and waste, especially suitable for experiment
Room and hospital's blood analysis room use, and are provided with double wedge in the flat surface of bizet in addition, facilitate rotation to take, in summary, this reality
It is simple with new structure, it is easy to use.
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.
