Arc transition can further facilitate the cleaning of rubber stopper, medical fluid is prevented to be contaminated.
In addition, being disposed with Teflon membranes and water vapor rejection outward on the outer wall of the bizet 1 and neck 2
Layer, the aqueous vapor separation layer be aluminium foil layer, aqueous vapor separation layer be located at the Teflon membranes away from 1 matrix of bizet with
The side of 2 matrix of neck.
Medical fluid is polluted in order to further decrease the generation of clast, while being reduced to the gas between rubber stopper and injection bottle 5
The influence of close property, as shown in Figure 1, the neck 2 is provided with shred holding up plate 4 far from one end of the bizet 1, the shred holding up plate 4 covers
The opening of one end set on the neck 2 far from the bizet 1, between the shred holding up plate 4, the bizet 1 and the neck 2
It is enclosed exfoliation slot 41, the thickness of the shred holding up plate 4 is less than the thickness in needle thorn portion 11.
In addition, as illustrated in fig. 1 and 2, the lower surface of bizet 1 is fixedly connected with wedge-shaped rubber circle 3, the outer wall of the neck 2
It is above circumferentially arranged to have several sealing rings 21；The annular groove for the sealing ring 21 insertion is provided on the inner wall of the injection bottle 5
6；When the sealing ring 21 is embedded in the annular groove 6, the lower surface of the end face of 5 opening of injection bottle and the bizet 1 it
Between distance be less than the wedge-shaped rubber circle 3 thickness.
The stability connected between neck 2 and injection bottle 5 is not only increased by the setting of sealing ring 21, rubber is stamped in improvement
The situation that medical fluid is surprisingly trickled down in 5 bottles of bottles of while falling of injection bottle of rubber plug, and medical fluid is prevented to flow out the entrance with pollutant, one
Determine to improve air-tightness in degree；When the sealing ring 21 is embedded in the annular groove 6 on the injection bottle 5, the injection bottle 5 is open
The distance between the end face at place and the lower surface of the bizet 1 are less than the thickness of the wedge-shaped rubber circle 3, so that the wedge shape rubber
Cushion rubber 3 is upwarded pressure by the end face of 5 opening of injection bottle, the wedge-shaped rubber circle 3 away from the bizet 1 side with
The end face of 5 opening of injection bottle is inconsistent and generates elastic deformation, so that the end face of rubber stopper and injection bottle 5 fits closely, resistance
Gas-liquid transmission channel between disconnected rubber stopper and injection bottle 5, effectively improves the air-tightness of injection bottle 5.
In addition, in order to improve the air-tightness of wedge-shaped rubber circle 3, the side stated wedge-shaped rubber circle 3 and deviate from the neck 2
It is provided with the second v-depression 31, the shape of the wedge-shaped rubber circle 3 is the annular shape centered on the central axis of the bizet 1.
In order to improve the stability and service life of wedge-shaped rubber circle 3, the side of the close neck 2 on the bizet 1
It is additionally provided with annular groove 13, for being embedded in the wedge-shaped rubber circle 3, the thickness of the wedge-shaped rubber circle 3 is greater than the injection
The sum of the depth of the distance between the end face of 5 openings of bottle and the lower surface of the bizet 1 with the annular groove 13.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
It changes among the protection scope created still in the utility model.
