Abstract
This utility model relates to a kind of freeze dried vaccine dilution syringe needle; it comprises double head belt sword needle tubing; in the middle part of described double head belt sword needle tubing, position to the right is provided with colloid handheld component; protective sleeve; described protective sleeve comprises sleeve pipe and pullover; described sleeve pipe and pullover fastening use, and the internal diameter of the fastening projection of described sleeve pipe right-hand member and the external diameter of described colloid Handheld Division match.A kind of freeze dried vaccine dilution syringe needle is applied in freeze dried vaccine dilution by this utility model, is joined in lyophilizing bottle by diluent, avoid the numerous and diverse step needing repeatedly to extract diluent by the effect of lyophilizing bottle and diluent bottle pressure difference.
Description
Technical field
This utility model relates to a kind of syringe needle, particularly a kind of freeze dried vaccine dilution syringe needle.
Background technology
In present freeze dried vaccine dilution, the general syringe that adopts extracts the liquid such as diluent or other dilution vaccine, then inserts in freeze-dried vaccine by syringe needle, is pushed in freeze-dried vaccine bottle by liquid in syringe and dilute freeze dried vaccine.The method in use may need repeatedly to extract diluent and repeatedly dilute freeze-dried vaccine.
Utility model content
For the weak point mentioned in the problems referred to above, this utility model provides a kind of freeze dried vaccine to dilute syringe needle, is joined in lyophilizing bottle by diluent, avoid the numerous and diverse step needing repeatedly to extract diluent by the effect of lyophilizing bottle and diluent pressure of the inside of a bottle difference.
To achieve these goals, this utility model is realized by following technical scheme.
A kind of freeze dried vaccine dilution syringe needle, comprising:
Double head belt sword needle tubing, in the middle part of described double head belt sword needle tubing, position to the right is provided with colloid handheld component,
Needle tubing cover, described needle tubing cover is by sleeve pipe and pulloverly form, and described sleeve pipe and pullover fastening use, and the internal diameter of the fastening projection of described sleeve pipe right-hand member is greater than the external diameter of described colloid Handheld Division.
The right part of described double head belt sword needle tubing is provided with the protective sleeve of one and described double head belt sword needle tubing diameter matches.
Be provided with an anti-skidding projection on the right side of described colloid handheld component, the external diameter of described anti-skidding projection and the internal diameter of described protective sleeve match.
The beneficial effects of the utility model are:
By the effect of lyophilizing bottle and diluent pressure of the inside of a bottle difference, diluent is joined in lyophilizing bottle, avoid the numerous and diverse step needing repeatedly to extract diluent.This utility model structure is simple, and the operation of user is convenient in the setting of handheld component.

Detailed description of the invention
Below in conjunction with drawings and Examples, the detailed description of the invention that this utility model carries out is described in further detail.
As shown in Figure 1, a kind of freeze dried vaccine dilution of this utility model syringe needle, comprising:
Double head belt sword needle tubing 1, in the middle part of described double head belt sword needle tubing 1, position to the right is provided with colloid handheld component 2,
Needle tubing cover, described needle tubing cover is made up of sleeve pipe 5 and pullover 6, and described sleeve pipe 5 and pullover 6 fastens and uses, and the internal diameter of the fastening projection 7 of described sleeve pipe 5 right-hand member is greater than the external diameter of described colloid Handheld Division 2.
The right side of described double head belt sword needle tubing 1 is provided with the protective sleeve 3 of one and described double head belt sword needle tubing 1 diameter matches.
Be provided with one anti-skidding protruding 4 on the right side of described colloid handheld component 2, the internal diameter of the described anti-skidding external diameter of protruding 4 and described protective sleeve 3 matches.
During concrete use: arrest needle tubing cover; first pull up right side pullover 6; left side sleeve pipe 5 pulled up by hand-held protective sleeve 3; first right side syringe needle is inserted in diluent or other dilution liquid (comprising liquid vaccine); described diluent liquid is normal-pressure liquid; right side protective sleeve 3 is pulled up in hand-held colloid Handheld Division 2, this procedure avoids the pollution of double head belt sword needle tubing, ensures needle sterile.Be inverted by dilution bottle, be inserted into by left side syringe needle in lyophilizing bottle, it is low that lyophilizing bottle internal gas pressure comparatively releases liquid pressure of the inside of a bottle, utilizes pressure differential that diluent is flowed in lyophilizing bottle by double head belt sword syringe needle, complete vaccine dilution.Take off syringe needle after having diluted carry out clean to it and dispose.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for a person skilled in the art, this utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
