Description

Medicine feeder rubber plug

Technical Field

The utility model relates to the field of medical equipment, concretely relates to medicine feeder plug.

Background

Dispensers are indispensable injection tools in medical devices, and typically comprise a needle, a dispenser tube, a rubber plug and a dispenser pusher. When the conventional injection is carried out, the existing rubber plug design has defects that the liquid medicine can not be fully discharged, more liquid medicine is remained in a drug administration tube and a needle head, the waste exists, and the dosage required by organisms can not be reached. Meanwhile, the residual liquid medicine can be leaked, the environment is polluted, and the infection risk is also existed. Therefore, it is an urgent technical problem to be solved by those skilled in the art to design a drug delivery device rubber plug capable of fully discharging the drug solution and preventing the drug solution from leaking.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the defect that exists among the prior art, provide a ware plug of dosing, promote to arrange the medicine completely, avoid the liquid medicine water clock, sealing performance is good, save material, design benefit, convenient and practical.

In order to realize the purpose, the technical scheme of the utility model a design a ware plug of dosing, including the plug body with connect the cavity of dosing ware push rod, its characterized in that, plug body upper portion intermediate position is equipped with the round platform structure, and the round platform is connected with upper portion integrated into one piece, and the round platform has the tapering of following supreme shrink gradually, the round platform possesses the same axis with the cavity, the edge forms a cambered surface of bending down gradually to the round platform direction in the outside of upper portion, and the lower of cambered surface is located upper portion and round platform bottom junction. The further technical scheme is that the inner diameter of the bottom circular ring is equal to the inner diameter of the middle part. The design of the circular truncated cone structure is matched with the front end of the administration device and the inner space of the needle seat, so that the liquid medicine in the administration device and the needle seat can be fully discharged without residue. The design benefit of the cambered surface structure is ingenious, when the medicine feeder push rod is pushed, a plane is gradually formed on the upper portion, a convex cambered surface is formed when the medicine feeder push rod continues to be extruded, liquid medicine is fully discharged through matching, and meanwhile the sealing effect is enhanced. The cambered surface structure rebounds when the administration is finished, a negative pressure effect is generated, a small amount of residual liquid medicine in the needle tube is sucked back, and the liquid medicine is prevented from dripping and leaking due to the existence of the negative pressure effect. Meanwhile, the downward-bent cambered surface structure can save materials.

The further technical proposal is that the outer edge of the rubber plug body is provided with a sealing ring. The design of the sealing ring can enhance the sealing effect of the medicine feeder rubber plug and reduce the friction force between the rubber plug body and the medicine feeder barrel.

The further technical proposal is that the sealing ring is positioned at the upper end of the rubber plug body and is connected with the upper part into a whole.

The further technical proposal is that the sealing ring is arranged at the lower end of the rubber plug body.

The further technical proposal is that a plurality of sealing rings are arranged between the upper end and the lower end of the rubber plug body.

The utility model has the advantages and the beneficial effects that: the design of the circular truncated cone structure is matched with the front end of the administration device and the inner space of the needle seat, so that the liquid medicine in the administration device and the needle seat can be fully discharged without residue. The design of cambered surface structure is ingenious, and when promoting the ware push rod of dosing, upper portion forms a plane gradually, forms the cambered surface of an epirelief when continuing the extrusion, and the cooperation is fully discharged the liquid medicine, still has the sealed effect of reinforcing simultaneously. And when the ware push rod of dosing pushed away half, when the ware of dosing was placed at the desktop, can not cause syringe needle portion weeping yet, cambered surface structure kick-backs when dosing the end, produces the negative pressure effect, and remaining minimum liquid medicine is inhaled back in the needle tubing, and the existence of negative pressure effect has avoided the water clock of liquid medicine. Meanwhile, the downward-bent cambered surface structure can save materials. The design of sealing ring can strengthen the sealed effect of dosing ware plug, has reduced the frictional force between plug body and the ware barrel of dosing simultaneously.

Drawings

FIG. 1 is a schematic view of the drug delivery device of the present invention;

Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1, the utility model discloses a ware plug of dosing, including plug body 1 and the cavity 5 of connecting the ware push rod of dosing, its characterized in that, 2 intermediate positions on 1 upper portion of plug body are equipped with round platform 4 structures, and round platform 4 is connected with 2 integrated into one piece on upper portion, and round platform 4 has the tapering of supreme shrink gradually from the bottom down, round platform 4 and cavity 5 possess the

same axis

3, 2 outside edges in upper portion form a cambered surface of bending down gradually to round platform 4 direction, and the minimum of cambered surface is located upper portion and round platform bottom junction. Further, the outer edge of the rubber plug body 1 is provided with a sealing ring 6. Further the sealing ring 6 is positioned at the upper end of the rubber plug body 1 and is connected with the upper part 2 into a whole. Further the sealing ring 6 is arranged at the lower end of the rubber plug body 1.
