Abstract

Disclosed in the present invention an apparatus for operating a locking protrusion of a reuse prevention tool for a drug injection device, wherein when a pressurization flange of a syringe plunger is pressed, an injection liquid contained in a syringe barrel is injected, and when force applied to the pressurization flange is released after completing the injection of the injection liquid, the syringe plunger, the syringe barrel and a locking body are lifted from and drawn out of the reuse prevention tool due to extension of a spring, and then the locking is released as the locking protrusion of the reuse prevention tool for a drug injection device presses the pressurization flange, so that the syringe barrel and the locking body can be easily lifted after completed injection. In addition, even when the lifted syringe plunger is pressed again, the released locking protrusion is caught at an upper end of the reuse prevention tool with the syringe barrel descending, thereby preventing the reuse of the drug injection device.

Description

의약품 주입용 기구 재사용방지구의 록킹돌기 작동장치{lock process motion device of preventing reuse tool for disposable syringe}Lock process motion device of preventing reuse tool for disposable syringe

본 발명은 의약품 주입용 기구 재사용방지구의 록킹돌기 작동장치에 관한 것으로, 더욱 상세하게는 주사액이 주입될 때 주사기배럴을 록킹하는 록킹돌기가 주사기 주입 완료 후 해제되도록 하여 눌러진 주사기배럴이 압축된 스프링에 의해 용이하게 승강되도록 하고 사용된 주사기의 재사용을 방지하도록 한 의약품 주입용 기구 재사용방지구의 록킹돌기 작동장치에 관한 것이다.The present invention relates to a device for operating a locking protrusion of a device for preventing reuse of a drug injection device, and more particularly, a spring compressed by a compressed syringe barrel so that the locking protrusion that locks the syringe barrel when the injection solution is injected is released after completion of syringe injection. It relates to a locking protrusion operating device of a device for preventing reuse of a medicine injection device to be easily lifted and lowered by and to prevent reuse of used syringes.

일반적으로 주사기는 의료 용품 중 하나로, 주사액을 주사하거나 혈액을 채취하거나 샘플을 채취하는 등 다양한 용도로 사용되고 있다.In general, a syringe is one of 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 includes a syringe barrel containing an injection solution, a syringe plunger that pressurizes the inside of the syringe barrel to inject an injection solution or collects blood or a sample, and a syringe needle and a syringe connected to the upper discharge port 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 attached to the upper outlet of the syringe barrel, a syringe cap is attached, or a blood collection tool is combined.

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.It is a principle to use such a syringe once, which means that the used syringe leaves the patient's blood on the needle, and if the used syringe is used again, the pathogen (hepatitis, AIDS, etc.) contained in the blood of the previously injected person is different. Since it is spread 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 purchase cost of syringes, there are cases where once used syringes are reused without disposal, and even if they are used multiple times, they are being reused because they cannot be easily identified from the appearance of the patient. , Medical accidents have occurred several times, and hepatitis C has occurred collectively.

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 these events is that drug addicts frequently reuse drugs when inhaling drugs outside of medical institutions, and some medical institutions also frequently reuse disposable syringes for economic reasons to reduce expenditure on 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 transmission of the disease through the blood of others.

이에 따라 재사용이 방지되는 기술들이 다양하게 안출된 바 있다.Accordingly, various technologies that prevent 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 reusable structure, which is Patent No. 10-1750352, has been devised, which fixes a fixed body to the tip of the syringe by fusion or welding, and screw-connects the opening and closing body to the fixed body, and fixing it with the opening and closing body. A re-use prevention cover is further provided to cover the entire body, but the re-use prevention cover is provided with an upper body that is fitted to surround the outside of the opening and closing body and a lower body that is fitted to surround the outside of the fixed body, and connects the upper body and the lower body When the upper body is rotated in one direction with respect to the lower body, as well as the external force generated when the upper body is rotated in one direction, 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 opened and closed with the lower body. The body is separated from the fixed body, and reuse of the syringe can be checked by cutting the connection cutout, preventing reuse of the syringe. The upper body of the cover prevents reuse by firmly fixing the fixed body and the syringe. Not only is it easy to separate, but it also prevents safety accidents caused by connection cutouts.

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 and closing body separated from the fixed body is divided into an upper body and a lower body, and the connection cutout must be cut or cut so that the upper body is separated from the lower body, so that the upper body and the lower body are separated before use. Since reuse is prevented, the syringe needle coupling portion of the syringe once used is not only exposed to the outside, but also the pressing operation of the syringe plunger is possible, so that the reuse of the disposable syringe is not completely prevented.
