본 고안은 1회용 주사기를 재사용이 불가능하도록 하여 환자들이 불의의 피해를 입지 않도록 한 1회용 주사기에 관한 것이다.The present invention relates to a disposable syringe which makes it impossible to reuse the disposable syringe so that patients are not injured.

1회용 주사기는 1회 사용후에 폐기처분 하도록 되어 있으나 주사기를 구입하기 곤란한 사람, 다시말하면 마약사범등은 사용하였던 주사기를 다시 재사용할 수 있는 가능성이 있는 것이다.Disposable syringes are to be disposed of after one use, but those who have difficulty in purchasing syringes, ie drug offenders, have the potential to reuse the used syringes.

따라서 본 고안은 주사기를 이용하여 주사기 외통내에 삽입되어 있는 약제를 환자에게 완전히 투입하여 가스켓의 선단부에 고정된 밀대끝 삼각돌기가 외통의 내측 선단부에 밀착되면 가스켓 주앙으로 노출된 삼각돌기가 주사바늘 삽입부 내면 걸림턱에 삽입되면서 후퇴가 불가능하게 되어 결국 밀대와 가스켓의 후퇴가 불가능하게 되므로서 한 번 사용한 주사기는 다시 재활용할 수 없도록 한 것을 제안하는 것이다.Therefore, the present invention completely inserts the drug inserted into the syringe barrel using the syringe to the patient, and when the pusher tip triangular protrusion fixed to the tip of the gasket comes into close contact with the inner tip of the barrel, the triangular protrusion exposed to the center of the gasket is inserted into the needle. It is proposed that the syringes once used cannot be recycled because the retracting is impossible because the insert is inserted into the inner jaw and the retraction of the rod and the gasket is impossible.

상기한 목적을 달성하기 위하여 국내공개실용신안공보 제114호(공개번호 : 86-11522)에 기재된 1회용 주사기가 알려진 바 있다.In order to achieve the above object, the disposable syringe described in Korean Utility Model Publication No. 114 (Publication No .: 86-11522) has been known.

이는 돌환을 형성한 고무패킹의 삽입공에 피스톤의 돌기를 삽입고정시켜 주사기 몸체내에 삽입시키고 고무패킹의 하단 중앙부에 다수개의 절결홈이 형성된 탄성편을 축착하고 주사기 몸체 내부의 상부에 천공된 구멍에 피스톤의 돌기를 끼우고 떼기가 쉽게 하며, 하단에 형성된 주사침 연결부에 단턱을 형성시켜 탄성편이 걸려 피스톤의 왕복운동을 방지하여 주사기의 재사용을 방지하도록 한 것인바, 이는 고무재질로 된 고무패킹의 상부에 피스톤을 연결시키고 고무패킹의 하부로는 탄성편을 연결시키는 구조로 되어 결국 피스톤과 탄성편이 각각 제작되어 조립되어야 하기 때문에 작업성이 양호하지 못할 뿐만 아니라 탄성편이 고무패킹과 이완될 염려가 있어 소정의 목적을 달성하기 어렵고 제작단가도 높아지게 되어 1회용 주사기로 사용하기에는 사용자가 경제적인 부담을 안게 되었던 것이다.It is inserted into the syringe body by fixing the projection of the piston into the insertion hole of the rubber packing that formed the annular ring, and the elastic piece formed with a plurality of cutout grooves at the center of the lower end of the rubber packing is compressed and inserted into the perforated hole in the upper part of the syringe body. It is easy to insert and remove the protrusion of the piston, and by forming a stepped portion in the needle connection formed on the lower end to prevent the piston from reciprocating movement of the piston to prevent the reuse of the syringe bar, which is made of rubber material The piston is connected to the lower part of the rubber packing and the elastic piece is connected to the structure, and the piston and the elastic piece have to be manufactured and assembled, respectively, so that the workability is not good and the elastic piece may be loosened with the rubber packing. It is difficult to achieve the purpose of production and the manufacturing cost is also high, so it can be used as a disposable syringe. Users will ange was an economic burden.

본원 출원인은 상기한 목적을 손쉽게 달성하기 위하여 밀대의 선단부에 가스켓을 완전히 통과할 수 있는 삼각돌기와 삼각돌기 고정축을 일체로 형성하고 삼각돌기의 저면외경보다 삼각돌기 고정축의 상부외경이 작게하여 밀대와 가스켓이 분리될 염려가 없고 조립작업의 능률을 향상시켜 제작단가를 낮추게 한 것으로 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The applicant of the present application forms a triangular projection and a triangular projection fixed shaft integrally capable of completely passing the gasket to the tip of the push rod in order to easily achieve the above object, and the upper outer diameter of the triangular projection fixed shaft is smaller than the bottom outer diameter of the triangular projection so that the push rod and the gasket are There is no fear of separation and to improve the efficiency of the assembly work to lower the production cost as described in detail by the accompanying drawings as follows.

외통(1)내에 가스켓(3)을 선단부에 고정시킨 밀대(2)를 삽입하고, 외통(1)의 선단부로 주사기 바늘을 고정시킬 수 있도록 주사바늘 인입부(4)를 형성하며, 그 주사바늘 인입부(4)에 제어턱(5)을 형성한 통상의 것에 있어서 밀대(2)의 선단부에 삼각돌기(2a)와 삼각돌기 고정축(2b)을 일체로 형성하고 삼각돌기(2a)의 저면 외경보다 삼각돌기 고정축(2b)의 상부 외경이 작게하여 삼각돌기(2a)의 저면부가 걸림턱(2c)이 되도록 한 것이다.Insert the push rod 2 which fixed the gasket 3 to the tip part in the outer cylinder 1, and form the needle inlet part 4 so that the needle of the syringe can be fixed to the tip part of the outer cylinder 1, The needle In the usual case in which the control jaw 5 is formed in the inlet portion 4, the triangular protrusion 2a and the triangular protrusion fixing shaft 2b are integrally formed at the tip of the pusher 2, and the bottom surface of the triangular protrusion 2a. The upper outer diameter of the triangular projection fixing shaft 2b is smaller than the outer diameter so that the bottom portion of the triangular projection 2a becomes the locking step 2c.

그리고 밀대(2)의 내측면 상단부와 주사바늘 인입부(4)의 내측 하단부가 접하는 위치에 형성되는 제어턱(5)은 약간의 탄성을 갖고 단면이형으로 형성하여 제어턱(5)의 측면이 상면에서 저면부를 향하여 입구가 커지도록 경사면(5a)을 형성하였다.In addition, the control jaw 5 formed at the position where the upper end of the inner side of the push rod 2 and the inner lower end of the needle inlet 4 are in contact has a slight elasticity and has a cross-section. The inclined surface 5a was formed in a shape such that the entrance of the control jaw 5 was enlarged from the upper surface toward the bottom surface portion.

상기한 구조의 본 고안은 액상의 약제를 주사기 외통(1)의 내부로 인입시키는 과정에서는 삼각돌기(2a)가 주사기 외통(1)의 내측면 상단부와는 어느 정도의 간격이 있는 상태에서 약제를 인입시키게 되므로 밀대(2)를 후퇴시킴에 따라 약제는 주사기 외통(1)의 내부로 삽입이 되는데 이 상태는 알려진 주사기의 사용방법과 동일한 것이다.According to the present invention of the above structure, in the process of drawing the liquid medicine into the inside of the syringe barrel 1, the triangular protrusion 2a is separated from the upper end of the inner surface of the syringe barrel 1 with a certain amount of the drug. As it is introduced, the medicine is inserted into the inside of the syringe barrel 1 as the pusher 2 is retracted. This state is the same as the known method of using the syringe.

그러나 상기 상태에서 약제를 환자에게 부여시키기 위하여 밀대(2)를 전진시키게 되면 약제는 환자의 몸으로 투입이 되다가 최종 단계에 이르러 밀대(2)의 상단에 고정된 가스켓(3)의 상단면이 주사기 외통(1)의 내측 상단면과 밀접하게 되면 밀대(2)의 중앙 상단에 노출고정된 삼각돌기(2a)가 주사기 바늘 인입부(4)의 내측 하단면에 형성된 제어턱(5)을 통과하게 된다.However, when the pusher 2 is advanced to impart the drug to the patient in the above state, the drug is injected into the patient's body, and then the upper surface of the gasket 3 fixed to the top of the pusher 2 reaches the final stage. When it comes in close contact with the inner top surface of the outer cylinder 1, the triangular protrusion 2a exposed at the center top of the push rod 2 passes through the control jaw 5 formed at the inner bottom surface of the syringe needle inlet 4. do.

이때 제어턱(5)의 측면에는형의 경사면(5a)이 형성되어 있으므로 삼각돌기(2a)가 주사기 인입부(4)를 향하여 진행되는 것을 다소 방해하여 삽입되지만 일단 삼각돌기(2a)가 제어턱(5)을 완전히 통과하게 되면 첨부도면 제3도와 같은 상태로 되어 삼각돌기(2a)의 걸림턱(2c)이 제어턱(5)의 존재로 인하여 후퇴되지 못하게 되어 결국 주사기의 밀대(2)를 외통(1) 내부에서 진, 후진이 불가능한 상태로 되기 때문에 재사용이 불가능하게 되는 것이다.At this time, the side of the control jaw (5) Since the inclined surface 5a of the die is formed, the triangle protrusion 2a is inserted to interfere with the progress toward the syringe inlet 4, but it is inserted once the triangle protrusion 2a passes completely through the control jaw 5. As shown in FIG. 3, the latching jaw 2c of the triangular protrusion 2a cannot be retracted due to the presence of the control jaw 5, so that the push rod 2 of the syringe is moved forward and backward in the outer cylinder 1. Because this becomes impossible, it becomes impossible to reuse.

상술한 바와 같은 본 고안은 1회용 주사기를 재사용하는 것이 전혀 불가능하기 때문에 사용된 주사기가 불법 유통되더라도 재사용될 염려가 전혀 없어 국민보건 생활의 안전성을 기할 수 있는 유용한 것으로서 사용시 밀대와 가스켓이 분리될 염려가 없고 조립작업시 작업능률이 향상되어 저렴한 단가로 제조될 수 있으므로 사용자들에게 경제적인 부담을 주지않게 되는 것이다.As described above, the present invention is impossible to reuse the disposable syringe at all, so there is no fear that it will be reused even if the used syringe is illegally distributed, and it is useful to ensure the safety of public health. There is no economic burden on users because it can be manufactured at low cost because the work efficiency is improved during assembly work.
