Description

Technical Field

[0001] The utility model specifically relates to the technical field of rubber plug anti-puncture, in particular to a rubber plug capable of anti-puncture. Background Art

[0002] Rubber stoppers are mostly used in sealing devices. When used in medical equipment, they are used to seal medicine bottles. When a syringe needs to take medicine from the bottle, the syringe needs to penetrate the rubber stopper, and there will be residual rubber stopper particles inside the syringe. During the injection, when the syringe pushes the medicine, it will also push the residual particles in the rubber stopper into the human body, which will cause serious medical accidents. However, traditional rubber stoppers cannot be avoided during production and processing, so a puncture-proof rubber stopper is needed.

[0003] Chinese patent application number CN201810375007.X is a rubber stopper for medical injection; it includes a rubber stopper top cover, a rubber stopper, a valve plate seat, a valve plate, a rubber stopper compartment cover, a sealing rubber and a connecting rivet, the interior of the rubber stopper top cover is provided with a mounting groove for mounting the rubber stopper, the interior of the mounting groove is provided with a rubber stopper, and the bottom of the rubber stopper extends out of the rubber stopper top cover, connecting rivets are provided on both sides of the rubber stopper top cover, and the connecting rivets penetrate the upper surface of the rubber stopper top cover, the top upper surface of the rubber stopper, the top lower surface of the rubber stopper and the top lower surface of the rubber stopper top cover in sequence.

[0004] In the above patent, a valve plate is arranged inside the rubber plug, so that when the syringe penetrates the rubber plug, the valve plate is pushed up to rotate the valve plate, and the valve plate is effectively mounted by the rubber connecting seat. When the valve plate rotates, a gap is generated between the valve plate and the inside of the rubber plug, so that the liquid medicine leaks to the position between the sealing rubber plug and the top of the valve plate seat. In addition, in the above patent, a sealing rubber is arranged below the auxiliary puncture groove, so that when the syringe penetrates, the particles of the sealing rubber will remain in the syringe, so that when the injection is performed, the particles will enter the body along with the medicine.

[0005] Therefore, we provide a puncture-proof rubber stopper. In this device, a circular hole is opened at the center of the top cap, and a circular tube is fixedly installed in the circular hole. A sealing block is arranged on the top of the circular tube, and a tear sheet is arranged on the sealing block. When penetration is required, the sealing block is pulled out through the tear sheet. In this way, when the syringe needs to penetrate the rubber stopper, the needle end of the syringe fits with the inner wall of the circular tube, which can effectively prevent the presence of rubber stopper residue inside the syringe when the syringe and the rubber stopper are penetrated. Utility Model Content

[0006] The purpose of the utility model is to provide a puncture-proof rubber stopper. In the device, a round tube is arranged at the center of a top cap, so that when a syringe needs to penetrate the top cap, the syringe is inserted into the bottle through the round tube, which can effectively avoid the situation where rubber stopper particles remain inside the syringe when the syringe penetrates the top cap; so as to solve the problems raised in the background technology.

[0014] As a further technical solution of the utility model, the cross section of the rubber stopper body is T-shaped.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. When the utility model is used, the sealing block inside the top cap is pulled out through the tear sheet, so that when the syringe needs to penetrate the rubber stopper body, the syringe fits inside the round hole, which can effectively avoid the situation where rubber stopper particles remain inside the syringe when the syringe penetrates the top cap;

[0017] 2. The utility model, when not in use, the top of the round tube is sealed and fixed with the sealing block, which can effectively prevent the internal medicine from causing infection;

[0018] 3. In the utility model, a sealing ring is arranged on the surface of the insert sleeve, and the sealing ring is fitted with the inner wall of the bottle mouth, thereby effectively ensuring the sealing and stability between the rubber stopper body and the bottle mouth.
