Description
본 고안은 재사용이 방지되는 일회용 안전 주사기에 관한 것으로, 더욱 상세하게는 주사액을 주입하기 위해 주사기플런저를 주사기배럴측으로 밀어주면 스프링이 압축되었다가, 주사액 주입 후 밀어진 주사기플런저의 밀어주는 힘을 해제하면 압축된 스프링의 탄발력에 의해 주사기배럴의 전단 내측에 구비된 주사바늘유닛이 주사기배럴의 내부로 인입되어 주사바늘의 노출을 방지함에 따라, 주사기배럴의 내측으로 주사액이 재흡입 수용되지 않도록 하여 한 번 사용한 주사기의 재사용을 방지할 수 있는 재사용이 방지되는 일회용 안전 주사기에 관한 것이다.The present invention relates to a disposable safety syringe with prevention of reuse, and more specifically, to a disposable safety syringe with prevention of reuse, in which when a syringe plunger is pushed toward a syringe barrel to inject an injection liquid, a spring is compressed, and when the pushing force of the pushed syringe plunger is released after the injection liquid is injected, a syringe needle unit provided on the inside of the front end of the syringe barrel is drawn into the inside of the syringe barrel by the elastic force of the compressed spring, thereby preventing exposure of the injection needle, thereby preventing the injection liquid from being re-aspirated into the inside of the syringe barrel and thus preventing the reuse of a syringe used once.
일반적으로 일회용 주사기는 내부 공간부를 가지고 전단에 주사액주입구가 단차지게 형성된 주사기배럴과, 주사기배럴의 내부로 주사액을 투입하고 투입된 주사액을 투여 할 수 있도록 주사기배럴의 내부에서 삽입되고 전단에 가스켓이 결합된 주사기플런저와, 주사기배럴의 전단 주사액주입구에 장착되는 주사바늘로 구비되며, 주사바늘은, 주사기배럴의 전단에 구비되는 주사바늘플랜지에 나사결합되며, 주사바늘의 외부에는 주사바늘을 보호하면서 분리 가능한 주사바늘 보호캡이 결합되는 구조로 이루어져 있다.In general, a disposable syringe is composed of a syringe barrel having an internal space and a stepwise injection port formed at the front end, a syringe plunger that is inserted into the interior of the syringe barrel and has a gasket combined at the front end so as to inject an injection liquid into the interior of the syringe barrel and administer the injected injection liquid, and a syringe needle that is mounted on the injection port at the front end of the syringe barrel. The syringe needle is screw-connected to a needle flange provided at the front end of the syringe barrel, and a detachable needle protection cap is combined on the outside of the syringe needle to protect the syringe needle.
이러한 종래 일회용 주사기는, 주사바늘 보호캡을 제거하여 주사바늘을 노출시키고 노출된 주사기플런저를 당겨주면서 흡입되는 공기압을 이용하여 주사바늘을 통해 주사액을 흡입하고, 당겨진 주사기플런저를 밀어주면서 흡입된 주사액을 환자에게 투여하도록 하는 작용에 있어서는, 전혀 문제점이 발생되지 않고 있으나, 한번 사용한 주사기를 이용하여 재사용하는 경우가 발생되어 질병의 전파에 의한 감염은 물론 감염에 의한 사회적인 문제점을 야기시키게 된다.These conventional disposable syringes have no problems in the operation of removing the needle protection cap to expose the needle, pulling the exposed syringe plunger to draw the injection liquid through the needle using the inhaled air pressure, and then pushing the pulled syringe plunger to administer the drawn injection liquid to the patient. However, if the syringes are reused after being used once, this can cause infection through the spread of diseases as well as social problems due to infection.
즉, 일회용 주사기는, 감염사고를 방지하기 위해 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 other words, disposable syringes are, in principle, for single-use to prevent infection accidents. This is because the patient's blood remains on the syringe needle after use, and if the used syringe is reused, pathogens (hepatitis, AIDS, etc.) contained in the blood of the person who injected previously can be transmitted to another person, resulting in secondary infection accidents. Therefore, syringes should be used only once and then discarded.
그러나, 편리성이나 주사기 구입비용을 줄이기 위해 한번 사용한 주사기를 폐기처분하지 않고 재사용하는 경우가 있으며, 여러번 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 convenience or the cost of purchasing syringes, there are cases where syringes are reused instead of disposed of, and since the recipient cannot easily distinguish the syringe from its appearance even after multiple uses, they are being reused, which has become a social problem, and medical accidents have occurred several times, including a representative case of a mass outbreak of hepatitis C.
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.The main reason why these things happen is that drug addicts frequently reuse syringes when inhaling drugs in places other than medical institutions, and some medical institutions also often reuse disposable syringes for economic reasons to reduce spending on consumables.
이러한 결과로 인해, 재사용되는 주사기로 인한 감염의 기회가 높아지고, 나아가서는 타인의 혈액을 통해 질병이 전염되는 등의 사회적인 문제를 야기하고 있다.These results increase the chances of infection through reused syringes, and further cause social problems such as disease transmission through other people's blood.
이에 따라, 재사용이 방지되는 일회용 주사기 기술들이 다양하게 안출되고 있다.Accordingly, various disposable syringe technologies that prevent reuse are being developed.
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.For example, a syringe cap having a reuse prevention structure, registered patent number 10-1750352, has been developed, which fixes a fixed body to the tip of a syringe by fusion or welding, screws an opening/closing body to the fixed body, and further comprises a reuse prevention cover that entirely covers the opening/closing body and the fixed body, wherein the reuse prevention cover comprises an upper body fitted to cover the outside of the opening/closing body and a lower body fitted to cover the outside of the fixed body, and when the upper body and the lower body are connected integrally by a connecting cut portion, the external force generated by the rotation when the upper body is rotated in one direction relative to the lower body as well as the movement of the opening/closing body being pushed up from the fixed body causes the connecting cut portion to be cut so that the upper body and the opening/closing body are separated from the fixed body, and whether or not it has been reused can be checked by the cutting of the connecting cut portion, thereby preventing the reuse of the syringe, and the upper body of the reuse prevention cover is firmly fixed to the fixed body and the syringe so that it is separated from the lower body by the upper body of the lower body. It is designed to facilitate separation and prevent safety accidents caused by connecting and disconnecting parts.
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 conventional technology, the opening/closing body that is separated from the fixed body is divided into an upper body and a lower body, and the connecting cutting portion must be cut, i.e., disconnected, so that the upper body is separated from the lower body, and thus reuse is prevented depending on whether the upper body and the lower body are separated before use. Therefore, the syringe needle connecting portion of a syringe that has been used once is exposed to the outside as it is, and the pressing operation of the syringe plunger is possible, so it is impossible to completely prevent reuse of the disposable syringe.
더욱이, 구성이 복잡하게 이루어져 있기 때문에 생산과정에서의 생산비용의 증대를 가져오게 되어 일회용 주사기 비용을 증대시키게 되고, 생산성과 작업성이 크게 떨어지는 문제점이 있다.Moreover, because the composition is complex, it increases the production cost during the production process, which increases the cost of disposable syringes and causes a significant decrease in productivity and workability.
본 고안은 본 출원인에 의해 안출된 등록특허 10-2278970호의 문제점을 개선하기 위해 안출된 것으로, 간단한 구성에 의해 생산성 향상은 물론 조립에 따른 생산효율성을 크게 향상시키며, 비용절감을 유도할 수 있을 뿐만 아니라, 눌러진 주사기플런저의 누르는 힘을 해제하면, 주사바늘을 갖는 주사바늘유닛 전체가 자동으로 주사기배럴의 내측으로 완전히 인입되어 수용되도록 하여 한 번 사용한 주사기의 재사용을 방지할 수 있도록 한 재사용이 방지되는 일회용 안전 주사기를 제공함에 그 목적이 있다.The present invention has been made to improve the problems of registered patent No. 10-2278970 issued by the applicant of the present invention, and not only improves productivity through simple configuration, but also greatly improves production efficiency through assembly, and induces cost reduction, but also prevents reuse of a syringe that has been used once by automatically and completely retracting and receiving the entire syringe needle unit into the syringe barrel when the pressing force of the pressed syringe plunger is released. The purpose of the present invention is to provide a disposable safety syringe that prevents reuse.

도시된 바와 같이 본 고안은, 전단에 주사바늘유닛이 수용되는 바늘유닛수용부(11)가 구비되고 후단에 플랜지(12)가 구비되며 주사액이 수용되는 주사기배럴(10)과, 상기 주사기배럴(10)의 바늘유닛수용부(11)에 수용되어 일단이 바늘유닛수용부(11) 내면에 밀착되는 스프링(20)과, 상기 바늘유닛수용부(11)에 수용되되 상기 스프링(20)이 감싸지도록 수용되는 주사바늘유닛(30)과, 전단에 플런저캡(41)이 구비되고 후단에 플런저누름부(42)가 구비되며 상기 주사기배럴(10)의 내부에 끼워져 상기 플런저누름부(42)를 눌러주는 동작에 의해 상기 바늘유닛수용부(11)측으로 밀어지면서 주사기배럴(10)에 수용된 주사액을 주사바늘유닛(30)측으로 배출하는 주사기플런저(40)로 구비되는 안전 주사기에 관한 것이다.As described above, the present invention comprises a syringe barrel (10) having a needle unit receiving portion (11) for receiving a needle unit at the front end and a flange (12) at the rear end, and receiving an injection liquid; a spring (20) that is received in the needle unit receiving portion (11) of the syringe barrel (10) and has one end in close contact with the inner surface of the needle unit receiving portion (11); a syringe needle unit (30) that is received in the needle unit receiving portion (11) but is received so that the spring (20) is wrapped around it; a plunger cap (41) is provided at the front end and a plunger press portion (42) is provided at the rear end, and the plunger press portion (42) is inserted into the interior of the syringe barrel (10) and is pushed toward the needle unit receiving portion (11) by a motion of pressing the plunger press portion (42), thereby discharging the injection liquid received in the syringe barrel (10) toward the needle unit (30). It relates to a safety syringe equipped with a syringe plunger (40).
본 고안은, 상기 주사기플런저(40)의 플런저누름부(42)를 눌러주면 플런저캡(41)이 주사바늘유닛(30)측으로 전진 이동하면서 주사기배럴(10)의 내부에 수용된 주사액을 주사바늘유닛(30)을 통해 배출시켜 주사액이 투여되도록 한다.In the present invention, when the plunger pressing portion (42) of the syringe plunger (40) is pressed, the plunger cap (41) moves forward toward the injection needle unit (30), thereby discharging the injection fluid contained inside the syringe barrel (10) through the injection needle unit (30), thereby allowing the injection fluid to be administered.
또한, 주사액을 다 투여하고난 후에는 상기 플런저누름부(42)의 누르는 힘을 해제하면, 주사바늘유닛(30)이 스프링(20)의 탄발력에 의해 주사기배럴(10)의 내부측으로 완전히 인입되어 주사바늘유닛(30)의 주사바늘(N)이 외부로 노출되는 것이 차단된다.In addition, after the injection is fully administered, when the pressing force of the plunger pressing part (42) is released, the injection needle unit (30) is completely drawn into the inside of the syringe barrel (10) by the elastic force of the spring (20), thereby preventing the injection needle (N) of the injection needle unit (30) from being exposed to the outside.
이 때, 상기 스프링(20)의 탄발력에 의해 주사기배럴(10)의 내부측으로 인입되는 주사바늘유닛(30)은, 상기 주사기플런저(40)의 수용공간(44)에 인입되어 수용된다.At this time, the injection needle unit (30) that is drawn into the inside of the syringe barrel (10) by the elastic force of the spring (20) is drawn into and accommodated in the accommodation space (44) of the syringe plunger (40).
이에 따라, 한 번 사용하고 난 주사기의 주사바늘(N)이 주사기배럴(10)의 내부에 완전히 인입된 상태로 놓이게 됨에 따라, 주사액을 재 흡입시켜 주사액을 재 투여하는 것이 방지될 수 있어, 주사기 재사용에 따른 의료사고나 안전사고 및 감염사고를 미연에 방지할 수 있다.Accordingly, since the injection needle (N) of the syringe that has been used once is placed in a state where it is fully inserted inside the syringe barrel (10), the injection liquid can be prevented from being re-aspirated and re-administered, thereby preventing medical accidents, safety accidents, and infection accidents due to reuse of the syringe.
더욱이, 주사기배럴(10)의 전단 내측에 구비되어 노출된 주사바늘유닛(30)에 구비되는 주사바늘(N)이 주사기배럴(10)의 내부로 자동으로 인입되어 주사바늘(N)의 노출을 방지할 수 있어 사용성과 편의성을 크게 향상시킴은 물론, 주사바늘을 차단하기 위해 덮개를 씌우거나 하지 않아도 된다.Furthermore, the injection needle (N) provided in the exposed injection needle unit (30) provided on the front inner side of the syringe barrel (10) is automatically drawn into the inside of the syringe barrel (10), thereby preventing the exposure of the injection needle (N), which greatly improves usability and convenience, and eliminates the need to cover the injection needle.
이를 위해 본 고안의 상기 바늘유닛수용부(11)에는, 상기 주사바늘유닛(30)측으로 좁아지도록 경사진 테이퍼면(51)이 외측에 구비되고 내측에 탄성걸림턱(52)을 갖는 탄성록킹부(50)가 구비된다.To this end, the needle unit receiving portion (11) of the present invention is provided with an elastic locking portion (50) having an inclined tapered surface (51) on the outside so as to be narrower toward the injection needle unit (30) and an elastic locking protrusion (52) on the inside.
또한, 상기 주사바늘유닛(30)은, 주사바늘(N)이 중앙에 관통되게 끼워지고 상기 바늘유닛수용부(11)에 수용되고 둘레면에 상기 스프링(20)이 끼워져 위치되는 주사바늘유닛몸체(31)와, 상기 주사바늘유닛몸체(31)의 외면으로부터 돌출되어 상기 바늘유닛수용부(11)의 내면에 일단이 밀착되는 상기 스프링(20)의 타단이 밀착되는 스프링밀착돌기(32)와, 상기 주사바늘유닛몸체(31)의 끝단에 구비되어 상기 탄성록킹부(50))의 내측에 구비되는 탄성걸림턱(52)에 걸어지는 록킹돌기(33)와, 상기 주사바늘유닛몸체(31)의 외면에 구비되되 상기 바늘유닛수용부(11)의 내면과 마주보도록 위치되는 기밀부끼움홈(34)과, 상기 기밀부끼움홈(34)에 끼워지고 상기 바늘유닛수용부(11) 내면에 밀착되어 상기 주사기배럴(10)의 내부에 수용된 주사액이 상기 바늘유닛수용부(11)를 통해 외부로 배출되는 것을 차단하는 기밀부(35)로 구비된다.In addition, the injection needle unit (30) comprises a needle unit body (31) in which an injection needle (N) is inserted through the center and is accommodated in the needle unit receiving portion (11) and the spring (20) is fitted and positioned on the circumference, a spring engaging projection (32) protruding from the outer surface of the needle unit body (31) and having one end of the spring (20) fitted against the inner surface of the needle unit receiving portion (11) and the other end of the spring (20) fitted against the inner surface of the needle unit receiving portion (11), a locking projection (33) provided at the end of the needle unit body (31) and hooked onto an elastic engaging protrusion (52) provided on the inner side of the elastic locking portion (50), a sealing fitting groove (34) provided on the outer surface of the needle unit body (31) and positioned so as to face the inner surface of the needle unit receiving portion (11), and a spring (34) fitted into the sealing fitting groove (34) and The needle unit receiving portion (11) is provided with a sealing portion (35) that is in close contact with the inner surface of the needle unit receiving portion (11) and prevents the injection liquid contained inside the syringe barrel (10) from being discharged to the outside through the needle unit receiving portion (11).
상기 스프링(20)은, 일단이 바늘유닛수용부(11)의 내면에 밀착되고 타단은 상기 주사바늘유닛(30)의 스프링밀착돌기(32)에 밀착되는 것으로, 주사액을 투입하기 전, 압축된 상태로 위치되었다가, 주사액을 투입하기 위해 주사기플런저(40)가 주사바늘유닛(30)이 수용된 바늘유닛수용부(11)측으로 전진 이동될 때 압축이 해제되며, 주사기플런저(40)의 밀어주는 동작 즉, 상기 플런저누름부(42)의 눌러지는 힘을 해제하면, 압축이 해제된 스프링(20)의 탄발력에 의해 상기 주사바늘유닛(30)의 스프링밀착돌기(32)를 주사기배럴(10)의 내부측으로 빠르게 밀어주게 되어, 상기 주사바늘유닛(30)은 물론, 주사바늘(N)이 상기 수용공간(44)의 내부로 빠르게 인입되어 주사기배럴(10)의 내부에 위치된다.The spring (20) above is positioned in a compressed state with one end pressed against the inner surface of the needle unit receiving portion (11) and the other end pressed against the spring engaging projection (32) of the injection needle unit (30) before the injection liquid is injected, and when the syringe plunger (40) is moved forward toward the needle unit receiving portion (11) where the injection needle unit (30) is received in order to inject the injection liquid, the compression is released, and when the pushing motion of the syringe plunger (40), i.e., the pressing force of the plunger pressing portion (42) is released, the spring engaging projection (32) of the injection needle unit (30) is quickly pushed toward the inner surface of the syringe barrel (10) by the elastic force of the spring (20) that has been decompressed, so that not only the injection needle unit (30) but also the injection needle (N) is quickly drawn into the inside of the receiving space (44). It is located inside the syringe barrel (10).
본 고안의 상기 주사기플런저(40)의 플런저캡(41)에는 체결홈(43)이 구비되고, 상기 체결홈(43)에 체결되어 상기 주사기플런저(40)를 주사바늘유닛(30)측으로 밀어주는 동작에 의해 상기 바늘유닛수용부(11)측으로 밀어진 후, 상기 바늘유닛수용부(11)에 구비된 탄성록킹부(50)의 경사진 테이퍼면(51)을 밀어주면서 바늘유닛수용부(11)에 밀착되는 록킹해제구(60)가 구비된다.The plunger cap (41) of the syringe plunger (40) of the present invention is provided with a fastening groove (43), and when the syringe plunger (40) is fastened to the fastening groove (43) and pushed toward the needle unit (30) side by an action of pushing the syringe plunger (40), a locking release member (60) is provided that is pushed against the needle unit receiving portion (11) while pushing the inclined tapered surface (51) of the elastic locking member (50) provided in the needle unit receiving portion (11).
이와 같이 이루어진 본 고안은, 상기 록킹해제구(60)에 의해 상기 스프링(20)의 타단이 밀착된 스프링밀착돌기(32)를 갖는 주사바늘유닛(30)의 록킹돌기(33)가 걸어진 탄성록킹부(50)를 벌여주게 되고, 이에 따라, 탄성록킹부(50)와 주사바늘유닛(30)과의 록킹이 해제된다.The present invention, which is made in this manner, opens the elastic locking part (50) on which the locking projection (33) of the injection needle unit (30) having the spring engagement projection (32) to which the other end of the spring (20) is pressed by the locking release mechanism (60), and accordingly, the locking between the elastic locking part (50) and the injection needle unit (30) is released.
이를 위해 본 고안의 상기 록킹해제구(60)는, 상기 록킹해제구(60)의 내면에 돌출되어 상기 플런저캡(41)의 체결홈(43)에 끼워져 체결되는 체결돌부(61)와, 상기 탄성록킹부(50)의 경사진 테이퍼면(51)에 밀착되어 주사기플런저(40)의 밀어주는 동작에 의해 상기 경사진 테이퍼면(51)을 밀어주면서 탄성록킹부(50)를 벌어지도록 하는 외향진 록킹테이퍼면(62)으로 구비된다.To this end, the locking release member (60) of the present invention is provided with a locking projection (61) that protrudes from the inner surface of the locking release member (60) and is fitted into the locking groove (43) of the plunger cap (41) for locking, and an outwardly directed locking taper surface (62) that is in close contact with the inclined tapered surface (51) of the elastic locking member (50) and opens the elastic locking member (50) by pushing the inclined tapered surface (51) by the pushing motion of the syringe plunger (40).
이와 같이 이루어진 본 고안은, 상기 주사기플런저(40)의 플런저누름부(42)를 눌어주면, 상기 주사기플런저(40)의 플런저캡(41)이 탄성록킹부(50)측으로 전진 이동된다.The present invention, which is made in this manner, is such that when the plunger pressing portion (42) of the syringe plunger (40) is pressed, the plunger cap (41) of the syringe plunger (40) moves forward toward the elastic locking portion (50).
또한, 탄성록킹부(50)측으로 전진 이동한, 플런저캡(41)의 체결홈(43)에 체결돌부(61)가 끼워져 체결된 상기 록킹해제구(60) 역시 탄성록킹부(50)측으로 전진 이동한다.In addition, the locking release member (60) that is fastened by the fastening projection (61) being fitted into the fastening groove (43) of the plunger cap (41) that has moved forward toward the elastic locking member (50) also moves forward toward the elastic locking member (50).
이와 같이 록킹해제구(60)가 탄성록킹부(50)측으로 전진하면서, 록킹해제구(60)의 외향진 록킹테이퍼면(62)이 탄성록킹부(50)의 경사진 테이퍼면(51)에 밀착된 상태로 경사진 테이퍼면(51)의 내측으로 인입되면서 탄성록킹부(50)를 벌려주고, 이에 따라, 상기 탄성록킹부(50)의 탄성걸림턱(52) 역시 벌어지면서 상기 탄성걸림턱(52)에 걸어진 주사바늘유닛(30)의 록킹돌기(33)가 탄성걸림턱(52)으로부터 록킹이 해제된다.In this way, as the locking release member (60) moves forward toward the elastic locking portion (50), the outwardly directed locking taper surface (62) of the locking release member (60) is brought into close contact with the inclined taper surface (51) of the elastic locking portion (50) and is drawn inwardly of the inclined taper surface (51), thereby opening the elastic locking portion (50), and accordingly, the elastic engaging step (52) of the elastic locking portion (50) also opens, and the locking projection (33) of the syringe needle unit (30) that is caught on the elastic engaging step (52) is unlocked from the elastic engaging step (52).
이 때, 누르고 있던 주사기플런저(40)의 플런저누름부(42)의 누르는 힘을 해제하면, 상기 압축되었던 스프링(20)이 탄발력에 의해 상기 주사바늘유닛(30)이 빠르게 주사기배럴(10)의 내부측으로 이동하면서 주사바늘유닛(30)은 물론, 주사바늘유닛몸체(31)에 관통 구비되는 주사바늘(N)이 빠르게 상기 주사기플런저(40)의 수용공간(44)에 인입되어 상기 주사기배럴(10)의 내부에 수용됨에 따라, 주사기배럴(10)의 전단측으로 주사바늘(N)이 노출되지 않게 된다.At this time, when the pressing force of the plunger pressing part (42) of the syringe plunger (40) that was being pressed is released, the compressed spring (20) causes the injection needle unit (30) to quickly move toward the inside of the syringe barrel (10) due to the elastic force, and the injection needle unit (30) as well as the injection needle (N) penetrating the injection needle unit body (31) are quickly drawn into the receiving space (44) of the syringe plunger (40) and received inside the syringe barrel (10), so that the injection needle (N) is not exposed to the front end of the syringe barrel (10).
본 고안의 상기 록킹해제구(60)의 외면에는 복수개 캡고정돌기(63)가 돌출되고, 상기 복수개 캡고정돌기(63)에 끼워져 고정되는 복수개 캡고정홈(64)이 내면에 구비되고 상기 주사기배럴(10)의 내면에 밀착되는 록킹해제구지지캡(65)이 구비된다.The outer surface of the locking release mechanism (60) of the present invention has a plurality of cap fixing projections (63) protruding, a plurality of cap fixing grooves (64) fitted into and fixed by the plurality of cap fixing projections (63) are provided on the inner surface, and a locking release mechanism support cap (65) that is in close contact with the inner surface of the syringe barrel (10) is provided.
이와 같이, 록킹해제구(60)의 캡고정돌기(63)에 록킹해제구지지캡(65)의 캡고정홈(64)이 끼워져 고정되어 있기 때문에, 상기 록킹해제구(60)를 주사기배럴(10)의 내부에 지지할 수 있음은 물론, 록킹해제구지지캡(65)의 외면이 주사기배럴(10)의 내면에 밀착된 상태로 주사기플런저(40)가 밀어질 때, 주사바늘유닛(30)측으로 밀려 이동됨에 따라, 주사기배럴(10)의 내부에 수용된 주사액이 주사바늘유닛(30)의 주사바늘유닛몸체(31)를 관통하는 주사바늘(N)을 통해 배출되어 투여됨이 가능하다.In this way, since the cap fixing groove (64) of the locking release support cap (65) is fitted and fixed into the cap fixing projection (63) of the locking release port (60), the locking release port (60) can be supported on the inside of the syringe barrel (10), and when the syringe plunger (40) is pushed while the outer surface of the locking release support cap (65) is in close contact with the inner surface of the syringe barrel (10), it is pushed toward the injection needle unit (30), so that the injection liquid contained inside the syringe barrel (10) can be discharged and administered through the injection needle (N) penetrating the injection needle unit body (31) of the injection needle unit (30).
본 고안의 상기 주사기배럴(10)의 끝단에는, 상기 플런저누름부(42)를 눌러주는 동작에 의해 상기 바늘유닛수용부(11)측으로 주사기플런저(40)가 밀어지면서 주사액이 주사바늘유닛(30)을 통해 배출될 때, 상기 눌러지는 플런저누름부(42)가 밀착되어 플런저누름부(42)의 누름동작이 더 이상 진행되지 않도록, 상기 주사기배럴(10)의 끝단으로부터 돌출 연장되는 걸림부(71)가 구비된다.At the end of the syringe barrel (10) of the present invention, when the syringe plunger (40) is pushed toward the needle unit receiving portion (11) by the action of pressing the plunger pressing portion (42) and the injection liquid is discharged through the injection needle unit (30), a catch portion (71) that protrudes and extends from the end of the syringe barrel (10) is provided so that the pressed plunger pressing portion (42) is pressed against and the pressing action of the plunger pressing portion (42) does not proceed any further.
이와 같이 걸림부(71)가 구비되어 있음에 따라, 상기 주사기플런저(40)의 플런저누름부(42)를 눌러주는 동작에 의해 상기 주사기플런저(40)가 주사바늘유닛(30)측으로 전진 이동하면서, 상기 플런저캡(41)가 록킹해제구(60)가 전진 이동할 때, 상기 걸림부(71)에 플런저누름부(42)가 닿게 되어 플런저누름부(42)의 누름 동작이 더 이상 진행되지 않기 때문에, 상기 플런저누름부(42)를 계속해서 눌러주어 플런저캡(41)은 물론 록킹해제구(60)가 벌어진 탄성록킹부(50)의 내부를 완전히 통과하여 바늘유닛수용부(11) 내측으로 완전히 인입되는 것이 방지된다.As the engaging portion (71) is provided in this way, when the plunger pressing portion (42) of the syringe plunger (40) is pressed, the syringe plunger (40) moves forward toward the needle unit (30), and when the plunger cap (41) and the locking release portion (60) move forward, the plunger pressing portion (42) comes into contact with the engaging portion (71), so that the pressing motion of the plunger pressing portion (42) no longer proceeds. Therefore, by continuously pressing the plunger pressing portion (42), the plunger cap (41) as well as the locking release portion (60) are prevented from completely passing through the inside of the opened elastic locking portion (50) and being completely drawn into the inside of the needle unit receiving portion (11).
또한, 주사 전, 상기 주사기배럴(10)의 플런저누름부(42)가 외부로 노출되는 것을 차단하여 플런저누름부(42)가 눌러지는 것을 방지하도록, 상기 주사기배럴(10)의 끝단에 구비되는 걸림부(71)에 끼워지는 플런저보호덮개(70)가 구비된다.In addition, to prevent the plunger pressing part (42) of the syringe barrel (10) from being exposed to the outside before injection and prevent the plunger pressing part (42) from being pressed, a plunger protection cover (70) is provided that fits into a catch (71) provided at the end of the syringe barrel (10).
