Abstract
The utility model discloses a ditch cell type freeze -drying powder bottle plug, establish the stopper neck at freeze -drying powder bottle mouth including the gag with being used for filling in, the stopper neck is connected with the lower surface of gag, and the surface of stopper neck is provided with a plurality of and the unanimous slot of stopper neck axial, and the rib outer fringe surface that the clamp was established between the adjacent slot is provided with the arch. This ditch cell type freeze -drying powder bottle plug simple structure, bottle internal gas pressure communicates with each other through slot and bottle outer atmospheric pressure, reduces the difference of the inside and outside atmospheric pressure of freeze -drying powder bottle, and frictional force is great between stopper neck and the freeze -drying powder bottle mouth internal surface, is difficult for producing jump stopper phenomenon because of pressure in the bottle is greater than the outer pressure of bottle.
Description
Technical field
This utility model relates to medical product field, is specifically related to a kind of groove-shaped lyophilized powder bottle plug.
Background technology
Lyophilized injectable powder refers to and is dissolved in certain solvent in advance by medicine and adjuvant, freezing, under certain vacuum, and remaining dry powder after solvent distillation.Because lyophilization is carried out, at low temperatures for the material particularly suitable of many thermal sensitivitys such as protein.As medicament, lyophilized injectable powder bottle and plug seal necessary, otherwise external microbe, steam, air etc. enter injection bottle can affect drug quality.Usual plug used comprises gag and plug neck, plug neck is the center that downward convex shape is connected to gag lower surface, plug neck lower end is plug lobe, when said structure can make plug fill in bottleneck, in bottle, gas communicates with the outer gas of bottle, the gas be beneficial in bottle is by compression discharged, thus is avoided the generation of plug jumping phenomenon from groove.But because plug cervical region upper end is still provided with plug ring, therefore, need, by increasing bulge loop to increase the frictional force of plug lobe and bottleneck on plug lobe surface, to prevent plug jumping further.Bulge loop cross section of the prior art is generally semicircle or half elliptic, the poor effect of its plug-bouncing.Therefore, be necessary to improve the structure of lyophilized powder bottle plug groove-shaped in prior art.
Utility model content
The purpose of this utility model is to overcome the defect existed in prior art, provides the groove-shaped lyophilized powder bottle plug that a kind of structure is simple, plug-bouncing is effective.
For realizing above-mentioned technique effect, the technical solution of the utility model is: a kind of groove-shaped lyophilized powder bottle plug, it is characterized in that, comprise gag and for filling in the plug neck being located at lyophilized powder bottleneck, described plug neck is connected with the lower surface of gag, the outer surface of described plug neck is provided with several grooves axially consistent with described plug neck, and between adjacent described groove, the rib outer fringe surface of sandwiched is provided with projection.
Preferred technical scheme is, described groove is axially uniformly distributed along the outer surface of described plug neck.
Preferred technical scheme is, is provided with blind hole in described plug neck, and the opening of described blind hole is arranged on the free end end face of described plug neck.
Preferred technical scheme is, the hole depth of described blind hole is not less than the length of described groove.
Preferred technical scheme is, described projection is salient point, and the joint face of described salient point and rib outer fringe surface is half elliptic or triangle, and crowning and the described rib outer fringe surface of described salient point seamlessly transit.
Preferred technical scheme is, described projection is convex arc, and two ends and the rib outer fringe surface of described convex arc seamlessly transit, and the cross section of described convex arc is triangle.
Advantage of the present utility model and beneficial effect are:
This groove-shaped lyophilized powder bottle plug structure is simple, bottle internal gas pressure is communicated by the outer air pressure of groove and bottle, reduce the difference of lyophilizing powder bottle inner and outer air pressure, between plug cervical region and lyophilized powder bottleneck inner surface, frictional force is comparatively large, not easily produces plug jumping phenomenon because of the intrinsic pressure powerful pressure outside bottle of bottle.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model groove-shaped lyophilized powder bottle plug embodiment 1;
Fig. 2 is the structural representation of this utility model groove-shaped lyophilized powder bottle plug embodiment 2.
In figure: 1, gag; 2, neck is filled in; 3, groove; 4, rib; 5, blind hole; 6, salient point; 7, convex arc.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
Embodiment 1
As shown in Figure 1, the groove-shaped lyophilized powder bottle plug of embodiment 1, comprise gag 1 and for filling in the plug neck 2 being located at lyophilized powder bottleneck, plug neck 2 is connected with the lower surface of gag 1, the outer surface of plug neck 2 is provided with several grooves 3 axially consistent with plug neck 2, and between adjacent groove 3, rib 4 outer fringe surface of sandwiched is provided with projection.
Groove 3 is axially uniformly distributed along the outer surface of plug neck 2.
Be provided with blind hole 5 in plug neck 2, the opening of blind hole 5 is arranged on the free end end face of plug neck 2.
The hole depth of blind hole 5 is not less than the length of groove 3.
Projection is salient point 6, and salient point 6 is half elliptic with the joint face of rib 4 outer fringe surface, and crowning and rib 4 outer fringe surface of salient point 6 seamlessly transit.
Groove number on embodiment 1 plug is three.
Embodiment 2
As shown in Figure 2, embodiment 2 is with the difference of embodiment 1, and projection is convex arc 7, and two ends and the rib outer fringe surface of convex arc 7 seamlessly transit, and the cross section of convex arc 7 is triangle.
Groove number on embodiment 2 plug is four.
For the ease of the puncture of injection needle, the upper surface of gag is also provided with locating ring.
During use, the projection of plug cervical region pushes up pressure mutually with lyophilized powder bottleneck inner surface, when plug being filled in lyophilized powder bottleneck, bottle internal gas pressure is communicated by the outer air pressure of groove and bottle, reduce the difference of lyophilizing powder bottle inner and outer air pressure, between plug cervical region and lyophilized powder bottleneck inner surface, frictional force is comparatively large, not easily produces plug jumping phenomenon because of the intrinsic pressure powerful pressure outside bottle of bottle.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from this utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
