Description

Technical Field

[0001] The utility model belongs to the technical field of rubber stoppers and relates to a drip-proof rubber stopper. Background Art

[0002] An infusion rubber stopper is a rubber product widely used in the medical field, mainly for sealing infusion bottles or infusion bags. When taking medicine from a conventional infusion bottle, the infusion needle can be directly inserted into the rubber stopper to complete the medicine taking. However, the conventional rubber stopper does not have a protection structure for the medicine-taking needle, and more attention needs to be paid to the needle during outdoor rescue infusion, resulting in inconvenient use. Summary of the Invention

[0003] The purpose of the utility model is to provide an operation-convenient anti-drip rubber stopper for the above problems existing in the prior art.

[0004] The purpose of the utility model can be realized by the following technical solutions: an anti-drip rubber stopper, characterized in that it includes a rubber stopper main body, a hemispherical medicine-taking part is provided on the rubber stopper main body, a plurality of sealing members are annularly and evenly distributed on the hemispherical medicine-taking part, clamping grooves and clamping keys are provided on both sides of the sealing members, the clamping keys and the clamping grooves are mutually clamped, arc-shaped grooves are provided at the ends of the sealing members, and a plurality of the arc-shaped grooves are spliced to form a through hole.

[0005] In the above-mentioned anti-drip rubber stopper, a plurality of support ribs are provided on the hemispherical medicine-taking part.

[0006] In the above-mentioned anti-drip rubber stopper, a stopper mouth part is provided on the rubber stopper main body, and an outer covering part coaxial with the stopper mouth part is also provided on the rubber stopper main body.

[0007] In the above-mentioned anti-drip rubber stopper, a connecting part is provided between the hemispherical medicine-taking part and the rubber stopper main body.

[0008] In the above-mentioned anti-drip rubber stopper, a medicine-taking indication ring is provided on the hemispherical medicine-taking part.

[0009] Compared with the prior art, the anti-drip rubber stopper of the present utility model reduces the accidental dripping of liquid medicine by providing a hemispherical medicine-taking part on the rubber stopper and forming a sealed space through the mutual clamping of the sealing members, and can better fix the infusion needle at the same time. The hemispherical medicine-taking part can hold part of the liquid medicine, and when the operator is not convenient, the waiting time can be increased by turning it outwards to prevent air from entering the infusion device, increasing the practicability.

Detailed implementation mode

[0015] The following are specific embodiments of the present invention and in combination with the attached drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0016] As shown in Figure 1 , 2 , 3, and 4, this anti-drip rubber stopper includes the main body of the rubber stopper 2. The main body of the rubber stopper 2 is provided with a hemispherical medicine-taking part 3. A plurality of seals 5 are evenly distributed in a ring on the hemispherical medicine-taking part 3. Clamping grooves 10 and clamping keys 11 are provided on both sides of the seal 5. The clamping key 11 and the clamping groove 10 are mutually clamped. Arc-shaped grooves 12 are provided at the ends of the seals 5. A plurality of arc-shaped grooves 12 are spliced to form the through hole 4. When installing the rubber stopper, due to gas pressure, the hemispherical medicine-taking part 3 will protrude from the main body of the rubber stopper 2, and the seal 5 will turn outwards. When the needle is inserted to take medicine, after the needle tip is inserted, the internal air pressure is connected to the outside, and the hemispherical medicine-taking part 3 is squeezed inward. The liquid medicine inside is squeezed towards the pipeline under the action of pressure, reducing the operation time for the user to empty the air in the pipeline. When the hemispherical medicine-taking part 3 is squeezed inward, the seal 5 retracts inward, and the clamping keys 11 on both sides and the clamping grooves 10 are mutually clamped. The through hole 4 clamps the needle head and completes the sealing, preventing the internal liquid medicine from leaking to the outside.

[0017] Preferably, a plurality of support ribs 1 are provided on the hemispherical medicine-taking part 3. The support ribs 1 prevent the difficulty of needle insertion caused by the premature retraction of the hemispherical medicine-taking part 3 when the needle is inserted. By increasing the support strength of the hemispherical medicine-taking part 3, it prevents the hemispherical medicine-taking part 3 from turning outwards due to accidental pulling.

[0018] Preferably, a plug mouth part 8 is provided on the main body of the rubber stopper 2, and an outer covering part 7 coaxial with the plug mouth part 8 is also provided on the main body of the rubber stopper 2.

[0019] Preferably, a connecting part 6 is provided between the hemispherical medicine-taking part 3 and the rubber stopper body 2. The connection increases the volume of the hemispherical medicine-taking part 3, and the liquid medicine can accumulate directly between the plug opening part 8 and the hemispherical medicine-taking part 3. When the liquid medicine is used up and the operator has no time to handle it, the accumulated liquid medicine can be made to participate in the transportation by turning the hemispherical medicine-taking part 3 outwards, preventing air from entering the delivery pipe.

[0020] Preferably, a medicine-taking indication ring 9 is provided on the hemispherical medicine-taking part 3.

[0021] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0022] Although terms such as supporting rib 1, rubber stopper body 2, hemispherical medicine-taking part 3, through hole 4, seal 5, connecting part 6, outer covering part 7, plug opening part 8, medicine-taking indication ring 9, clamping groove 10, clamping key 11, arc-shaped groove 12, etc. are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.
