Description

Administrator

Technical field

This utility model relates to medical instruments field, particularly relates to a kind of administrator.

Background technology

Vaginitis, cervicitis etc. are common gynecological disease and frequently-occurring disease, and exterior-applied gel occurs, and have solved the problem that suppository exists, but also have the problem of administration inconvenience, and also there is same problem in anum administration.

The Chinese patent publication number that our company released in the past is " CN2899827 ", a kind of " exterior-applied gel administrator " disclosed, what the cylindrical shell inner push-rod all used is PE (polyethylene) material, this material characteristics elastic restoring force is relatively poor, during because of barrel designs for the ease of delivery, designed certain tapering, when the push rod that has just come out is pushed to the top is smaller-diameter portion (will assemble in producer), will be compressed or be cooled off the back so for a long time when formal fill medicine, being beaten to the lower end is diameter major part, owing to the relatively poor reason of elastic restoring force can cause the relatively poor easy-to-leak liquid of sealing between push rod and the cylindrical shell.Because push rod is a concave surface, is pushed into cylinder top and also has the space, the inside has air.During the fill medicine, top by the shutoff fill time the inside air can not arrange, causing has the aeration appearance in the medicine, even also influences the loading amount instability.

Summary of the invention

The purpose of this utility model is to provide a kind of air influence of not having, can leakage, and simple in structure, easy to use, safe and sanitary, administrator with low cost.

The purpose of this utility model and solve its technical problem underlying and realize by the following technical solutions: according to the administrator that the utility model proposes, comprise cylindrical shell, push rod and sleeve pipe, the anterior thin rear portion of cylindrical shell is thick, be step between the front and rear part, the anterior top closure of cylindrical shell center is provided with the hole, and sleeve pipe entangles the cylindrical shell front portion, its external diameter is less than cylindrical shell rear portion internal diameter, push rod is positioned at cylindrical shell, and push rod and cylinder inboard wall are and are slidingly matched, and wherein: the push rod top is provided with rubber stopper.

Above-mentioned administrator, wherein: the rubber stopper surface is the plane

Above-mentioned administrator, wherein: cannula tip inner surface center is provided with a boss, and is corresponding with the hole.

This utility model compared with prior art has tangible advantage and beneficial effect, after the push rod top adds a rubber stopper, because the rubber stopper elastic restoring force is extremely strong, can also recover former state after promptly being compressed, and has guaranteed that sealing is better between push rod and the cylindrical shell.Add and rubber stopper is made the plane cooperate with cylindrical shell and almost do not have the slit, can discharge the inside has air influence.Thereby, simple in structure, easy to use, can not cause the unnecessary waste of medicine, and safety and sanitation, can not cause infection because of reasons such as hands are unclean.

The specific embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is user mode figure of the present utility model.

Labelling among the figure:

1, cylindrical shell; 2, push rod; 3, rubber stopper; 4, sleeve pipe; 5, hole; 6, boss.

The specific embodiment

Below in conjunction with accompanying drawing and preferred embodiment, to according to its specific embodiment of administrator, structure, feature and the effect thereof that the utility model proposes, describe in detail as after.

Referring to accompanying drawing, administrator of the present utility model comprises cylindrical shell 1, push rod 2 and sleeve pipe 4, and cylindrical shell 1 anterior thin rear portion is thick, be step between the front and rear part, cylindrical shell 1 anterior top closure center is provided with hole 5, and sleeve pipe 4 entangles cylindrical shell 1 front portion, and its external diameter is less than cylindrical shell rear portion internal diameter, push rod 2 is positioned at cylindrical shell 1, push rod 2 afterbodys and cylindrical shell 1 inwall are and are slidingly matched, and wherein: push rod 2 tops are provided with rubber stopper 3, and rubber stopper 3 surfaces are the plane.Inner surface center, sleeve pipe 4 top is provided with a boss 6, and is corresponding with hole 5, flows out to avoid medicine.

Concrete using method is: the cylindrical shell 1 anterior cavity of earlier medicine being packed into, take off sleeve pipe 4, then administrator is put into intravaginal, sleeve pipe 4 inserts cylindrical shell 1 rear portion and contacts with push rod 2 afterbodys, slowly promote sleeve pipe 4 and the intravital medicine in cylindrical shell 1 anterior chamber is extruded by hole 5, place the affected part by push rod 2.

The above, it only is preferred embodiment of the present utility model, be not that this utility model is done any pro forma restriction, any technical solutions of the utility model content that do not break away from,, all still belong in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did according to technical spirit of the present utility model.
