Abstract

According to the present invention, disclosed is a locking device for preventing the re-operation of a reuse prevention tool for drug injection. When a pressure flange of a syringe plunger is pressed to inject an injection solution, the injection solution contained in a syringe barrel is injected. When the pressing force on the pressure flange of the syringe plunger is released after the injection is completed, as a spring is extended, the syringe plunger, the syringe barrel, and the locking device are lifted up and out from the reuse prevention tool, and a needle coupling part of the syringe barrel is prevented from being drawn into the reuse prevention tool and exposed. Since the locking device is locked by hanging on the reuse prevention tool, the syringe barrel is prevented from descending even when the lifted syringe plunger is pressed again, thereby preventing reuse. As the syringe barrel does not descend and retract toward the reuse prevention tool, it is possible to prevent a syringe needle from being exposed, so that the reuse of a drug injection tool is more reliably prevented.

Description

의약품 주입용 기구 재사용방지구의 재작동 방지 록킹장치{locking device of preventing reuse tool for disposable syringe}Locking device of preventing reuse tool for disposable syringe

본 발명은 의약품 주입용 기구 재사용방지구의 재작동 방지 록킹장치에 관한 것으로, 더욱 상세하게는 일회용주사기의 주사액 주입이 완료된 후 눌러진 주사기 배럴이 압축된 스프링의 신장력에 의해 승강되어 록킹되도록 함에 따라 승강된 주사기 배럴이 눌러짐이 방지되어 의약품 주입용 기구의 재사용을 방지할 수 있도록 한 의약품 주입용 기구 재사용방지구의 재작동 방지 록킹장치에 관한 것이다.The present invention relates to a locking device for preventing the re-operation of a device for drug injection, and more particularly, the syringe barrel pressed after completion of injection of a disposable syringe is lifted and locked by the extension force of the compressed spring. It relates to a locking device for preventing the re-operation of a device for drug injection, which prevents the syringe barrel from being pressed to prevent reuse of the device for drug injection.

일반적으로 주사기는 의료 용품 중 하나로, 주사액을 주사하거나 혈액을 채취하거나 샘플을 채취하는 등 다양한 용도로 사용되고 있다.In general, a syringe is one of the medical supplies, and is used for various purposes such as injecting an injection solution, collecting blood, or collecting a sample.

이와 같은 주사기는, 주사액이 담겨지는 주사기배럴과 주사기배럴 내부를 가압하여 주사액을 주사하거나 혈액 또는 샘플을 채취하는 주사기플런저와 주사기배럴의 상단 토출구에 연결되어 주사액을 피부속으로 주사하는 주사기니들과 주사기니들을 보호하는 주사기캡으로 이루어져 있으며, 사용 용도에 따라 주사기배럴 상단 토출구에 주사기니들을 결합하거나 주사기캡을 결합하거나 또는 채혈 도구를 결합하여 사용하고 있다.Such a syringe is connected to a syringe barrel containing an injection solution and a syringe plunger that injects an injection solution or collects blood or a sample by pressing the inside of the syringe barrel, and a syringe needle and a syringe that is connected to the upper outlet of the syringe barrel to inject the injection solution into the skin It consists of a syringe cap that protects the needle, and depending on the intended use, a syringe needle is coupled to the top outlet of the syringe barrel, a syringe cap is coupled, or a blood collection tool is used.

이러한 주사기는 일회 사용하는 것이 원칙인 것으로, 이는 사용한 주사기는 주사바늘에 환자의 혈흔이 남게 되고 사용한 주사기를 재차 사용하게 되면 전에 주사한 사람의 혈흔에 포함된 병원균(간염, 에이즈 등)이 다른 사람에게 전파되어 2차 감염사고가 발생되기 때문에, 주사기는 한번만 사용하고 폐기처분여야 한다.In principle, these syringes are to be used once, which means that the used syringe leaves a patient's bloodstain on the needle, and when the used syringe is used again, the pathogens (hepatitis, AIDS, etc.) contained in the bloodstain of the person who injected it before are different. Because it spreads to people and causes a secondary infection, the syringe should be used only once and disposed of.

그러나, 편리성이나 주사기 구입비용을 줄이기 위해 한번 사용한 주사기를 폐기처분하지 않고 재사용하는 경우가 있으며, 여러 번 사용하여도 피시술자가 외관상으로 쉽게 판별할 수 없기에 재사용되고 있어서 사회적 문제로 대두되고 있는 실정이며, 수차례 의료 사고가 발생되며 대표적으로는 C형 간염이 집단적으로 발생한 사건이 있다.However, in order to reduce the convenience or cost of purchasing a syringe, there are cases where a syringe that has been used once is reused without disposing of it, and even after using it several times, it is reused because the recipient cannot easily identify it visually, which is a situation that is emerging as a social problem. , a number of medical accidents occur, and hepatitis C is a representative case.

이러한 일들이 일어나는 대표적인 이유로는 약물 중독자들이 의료기관이 아닌 곳에서 약물을 흡입할 때 빈번히 재사용하는 일들이 발생하고 있으며, 또한 일부 의료기관에서도 소모품의 지출을 줄이기 위한 경제적인 이유로 일회용 주사기를 재사용하는 일들이 종종 발생하고 있다.A typical reason for this to happen is that drug addicts frequently reuse drugs when inhaling drugs in non-medical institutions. Also, some medical institutions often reuse disposable syringes for economic reasons to reduce consumption of consumables. is occurring

이러한 결과로 인해, 재사용되는 주사기로 인한 감염의 기회가 높아지고, 나아가서는 타인의 혈액을 통해 질병이 전염되는 등의 사회적인 문제를 야기하고 있다.As a result of this, the chance of infection due to the reused syringe increases, and furthermore, it causes social problems such as the transmission of diseases through the blood of others.

이에 따라 재사용이 방지되는 기술들이 다양하게 안출된 바 있다.Accordingly, various technologies for preventing reuse have been devised.

일예로, 등록특허 10-1750352호인 재사용 방지 구조를 갖는 주사기 캡이 안출된 바 있으며, 이는 주사기 선단에 고정몸체를 융착 또는 용착에 의해 고정하고 개폐몸체를 고정몸체에 대해 나사 결합하며 개폐몸체와 고정몸체를 전체적으로 감싸는 재사용 방지커버를 더 구비하되 재사용 방지커버를 개폐몸체의 외측을 감싸도록 끼워지는 상부몸체와 고정몸체의 외측을 감싸도록 끼워지는 하부몸체로 구비하고 상부몸체와 하부몸체를 연결절취부에 의해 일체로 연결하여 사용할 때 상부몸체를 하부몸체에 대해 일방향 회전시킬 때 발생되는 회전에 따른 외력은 물론 개폐몸체가 고정몸체로부터 밀려올라가는 동작에 의해 연결절취부가 절취되어 상부몸체가 하부몸체 및 개폐몸체가 고정몸체로부터 분리되도록 하고 연결절취부의 절취에 의해 재사용 여부를 확인할 수 있어 주사기의 재사용을 방지할 수 있도록 하며 고정몸체와 주사기와의 견고한 고정에 의해 재사용 방지커버의 상부몸체가 하부몸체로부터의 분리가 용이하게 이루어지도록 함은 물론 연결절취부에 의한 안전사고를 방지할 수 있도록 하고 있다.As an example, a syringe cap having a re-use prevention structure has been devised, which is registered in Patent No. 10-1750352, which fixes the fixed body to the tip of the syringe by fusion or welding, and screws the opening and closing body to the fixed body, and is fixed with the opening and closing body. It further includes a reuse prevention cover that surrounds the body as a whole, but the reuse prevention cover is provided with an upper body fitted to surround the outside of the opening and closing body and a lower body fitted to surround the outside of the fixed body, and a cutout connecting the upper body and the lower body When the upper body rotates in one direction with respect to the lower body, the external force generated when the upper body is rotated in one direction with respect to the lower body as well as the connection cutout is cut by the movement of the opening and closing body being pushed up from the fixed body, so that the upper body is connected to the lower body and opening and closing The body is separated from the fixed body and reuse of the syringe can be checked by cutting the connection cutout to prevent the reuse of the syringe. The upper body of the reuse prevention cover is separated from the lower body by the firm fixation between the fixed body and the syringe. In addition to making the separation easier, it is also designed to prevent safety accidents caused by cut-outs.

그러나, 이러한 종래 기술은 고정몸체로부터 분리되는 개폐몸체가 상부몸체와 하부몸체로 구분되어 있으며, 연결절취부를 절취 즉 끊어주어야 상부몸체가 하부몸체로부터 분리되도록 하여 사용 전 상부몸체와 하부몸체의 분리여부에 의해 재사용을 방지하도록 하고 있기 때문에, 한번 사용한 주사기의 주사기니들 결합부가 그대로 외부에 노출됨은 물론 주사기플런저의 누름작동이 가능하게 되어 일회용주사기의 재사용을 완전히 방지하지는 못하고 있는 실정이다.However, in this prior art, the opening/closing body separated from the fixed body is divided into an upper body and a lower body, and the connection cutout has to be cut off so that the upper body is separated from the lower body, so whether the upper body and the lower body are separated before use Since the reuse is prevented by the , the syringe needle coupling portion of the once used syringe is exposed to the outside as it is, and the pressing operation of the syringe plunger is possible, so that the reuse of the disposable syringe cannot be completely prevented.

본 발명은 주사액을 주입할 때 주사기배럴이 눌러지도록 하고 주사액 주입이 완료되어 주사기배럴의 누르는 힘을 해제하면 눌러진 주사기배럴이 스프링의 복귀력에 의해 승강되면서 재사용방지구와 록킹되어 주사기배럴이 더 이상 눌러지지 않도록 하고 록킹된 상태에서 주사기니들결합부가 재사용방지구 내부로 인입되어 위치되어 의약품 주입용 기구의 재사용을 확실하게 방지할 수 있도록 한 의약품 주입용 기구 재사용방지구의 재작동 방지 록킹장치를 제공함에 그 목적이 있다.The present invention is such that the syringe barrel is pressed when the injection solution is injected, and when the injection solution injection is completed and the pressing force of the syringe barrel is released, the pressed syringe barrel is raised and lowered by the return force of the spring and is locked with the reuse prevention device so that the syringe barrel is no longer To provide a locking device to prevent re-operation of the drug injection device reuse prevention device so that it is not pressed and the syringe needle coupling part is retracted into the reuse prevention device in the locked state to reliably prevent the reuse of the medicine injection device. There is a purpose.

상기 목적을 달성하기 위한 수단으로 본 발명인 의약품 주입용 기구 재사용방지구의 재작동 방지 록킹장치는, 내부에 주사액이 담겨져 수용되는 주사기배럴과 상기 주사기배럴의 내부를 가압하여 눌러주고 가압플랜지를 갖는 주사기플런저와 상기 주사기배럴의 외면을 덮어 재사용을 방지하는 재사용방지구를 포함하는 일회용주사기 재사용방지구의 재작동 방지 록킹장치에 있어서, 주사기플런저의 가압플랜지를 눌러주는 동작에 의해 상기 주사기플런저가 재사용방지구측으로 하강인입되어 주사액 주입이 이루어지고 상기 주사기플런저의 눌러주는 힘을 해제하면 재사용방지구측으로 하강인입된 주사기배럴과 동시에 승강되어 주사기배럴의 니들결합부를 재사용방지구의 내측으로 인입시켜 주사기의 재사용이 방지되도록, 상기 주사기배럴과 상기 재사용방지구 사이에 구비되는 록킹장치가 구비되어 이루어진다.As a means for achieving the above object, the locking device for preventing the re-operation of the device reuse prevention device for drug injection according to the present invention is a syringe barrel containing an injection solution contained therein, and a syringe plunger having a pressure flange and pressurizing the inside of the syringe barrel In the locking device for preventing the re-operation of a disposable syringe including a re-use prevention device for preventing reuse by covering the outer surface of the syringe barrel, the syringe plunger moves toward the reuse prevention device by pressing the pressure flange of the syringe plunger. When the syringe plunger is pushed down and the pressure is released, the syringe barrel is moved down and retracted at the same time to the reuse prevention device, and the needle coupling part of the syringe barrel is drawn into the reuse prevention device to prevent reuse of the syringe. , A locking device provided between the syringe barrel and the reuse prevention device is provided.

본 발명은 주사액을 주입하기 위해 주사기플런저의 가압플랜지를 눌러주면 주사기배럴에 담겨진 주사액이 주입되고, 주사액 주입이 완료 후 누르고 있던 주사기플런저의 가압플랜지에 대한 누르는 힘을 해제하면 압축된 스프링의 압축력이 해제되면서 스프링이 신장되는 것에 의해 재사용방지구로부터 주사기플런저와 주사기배럴 및 록킹장치가 승강 인출되어 주사기배럴의 니들결합부가 재사용방지구 내측으로 인입되어 노출됨이 방지되며 록킹장치가 재사용방지구에 걸어져 록킹되기 때문에 승강된 주사기플런저를 다시 누르더라도 주사기배럴이 하강되는 것이 방지되어 재사용을 방지할 수 있으며, 주사기배럴이 재사용방지구측으로 하강 인입되지 않음에 따라 주사기니들이 노출되는 것을 방지할 수 있어 의약품 주입용 기구의 재사용이 더욱 확실하게 방지된다.In the present invention, when the pressure flange of the syringe plunger is pressed to inject the injection solution, the injection solution contained in the syringe barrel is injected, and when the pressing force on the pressure flange of the syringe plunger pressed after the injection solution injection is completed is released, the compression force of the compressed spring is As the spring is released as it is released, the syringe plunger, syringe barrel and locking device are lifted up and out from the reuse prevention device, preventing the needle coupling part of the syringe barrel from being drawn into the reuse prevention device and being exposed, and the locking device is hung on the reuse prevention device. Because it is locked, even if the elevated syringe plunger is pressed again, the syringe barrel is prevented from descending and reused, and the syringe needle is prevented from being exposed as the syringe barrel does not descend and retract to the reuse prevention port. Re-use of equipment is more reliably prevented.
