본 발명은 실린더의 내부에 결합되는 연결부재와 주사바늘 고정구를 일체로 제조하여 구성된 일회용 주사기에 관한 것으로, 특히 주사바늘 고정구의 외측면에 결합돌기를 형성하여 주사바늘과 일체로 제조하여 이를 실린더의 결합홈에 결합함으로서 제조공정 및 조립공정이 간편하여 생산성의 향상은 물론 주사기의 사용시 주사액의 잔류량을 최소화하여 사용의 편리성이 증대되는 안전 수거용 일회용 주사기를 제공하기 위한 것이다.The present invention relates to a disposable syringe configured by integrally manufacturing the connecting member and the needle fixture which is coupled to the inside of the cylinder, in particular, by forming a coupling protrusion on the outer surface of the needle fixture to manufacture integrally with the needle and the It is to provide a disposable collection syringe for safe collection by increasing the convenience of use by minimizing the residual amount of the injection solution when using the syringe as well as the productivity and the assembly process is simple by coupling to the coupling groove.

현재 일회용 주사기의 사용시 2차 감염의 우려로 주사후 주사바늘을 보호캡으로 보호하여 수거하고 있거나 또는 주사바늘을 실린더의 내부로 몰입시켜 수거하고 있는 것이다.Currently, disposable syringes are collected by protecting the needles with a protective cap after injection for fear of secondary infection, or by collecting the needles into the cylinder.

전기의 주사바늘을 캡으로 보호하여 수거하는 방법은 수거시에 작업자의 부주의로 인하여 보호캡이 이탈되는 경우가 허다하여 주사바늘이 그대로 노출되므로 2차 감염의 우려가 많은 것이다.The method of collecting and protecting the electric needle with a cap is a concern of secondary infection because the needle is often exposed due to the carelessness of the worker during collection.

따라서 이를 방지하기 위하여 주사바늘을 실린더에 몰입하여 안전하게 수거하는 일회용 주사기가 제안되고 있으며 이는 제5도에 도시한 바와같이 원통형의 실린더(101)의 상단 내부로 일정 간격을 유지하여 다수개의 괘합돌조(102)를 형성하여 이에 내측으로는 나선부(103)와 중앙으로는 주사액 통로(106)가 일자로 형성된 연결부재(104)를 삽입하여 결합한 후 상기 나선부(103)에 주사바늘이 고정된 주사바늘 고정구(105)를 나사식으로 결합하여 사용하고 있는 것이다.Therefore, in order to prevent this, a disposable syringe that safely collects the needle by immersing it in the cylinder has been proposed, which maintains a predetermined distance inside the upper end of the cylindrical cylinder 101 as shown in FIG. 102 is inserted into the spiral portion 103 and the injection passage 106 in the center is inserted into the coupling member 104 formed by the date and coupled to the injection needle is fixed to the spiral portion 103 The needle fixture 105 is used by screwing together.

상기한 종래의 일회용 주사기는 주사액의 주사후 플런저(108)를 끝까지 밀게되면 피스톤(107)의 일측에 형성된 고정돌기(110)가 주사액 통로(106)로 삽입되면서 연결부재(104)를 고정하게 되고, 이후 플런저(108)를 반대 방향으로 당기게 되면 실린더(101)의 내부에 고정되어 있던 연결부재(104)와 주사바늘 고정구(105)가 플런저(108)와 함께 당겨지게 되고, 이후 플런저(108)의 상단 즉 피스톤(107)의 하측에 형성된 절단부(109)를 절단하여 주사기를 안전하게 수거할 수 있는 것이다.When the conventional disposable syringe pushes the plunger 108 to the end after injection of the injection liquid, the fixing protrusion 110 formed on one side of the piston 107 is inserted into the injection liquid passage 106 to fix the connecting member 104. Then, when the plunger 108 is pulled in the opposite direction, the connecting member 104 and the needle fixture 105 fixed inside the cylinder 101 are pulled together with the plunger 108, and then the plunger 108 By cutting the cutting unit 109 formed at the upper end of the piston 107, that is, the syringe can be safely collected.

그러나 상기한 일회용 주사기는 사용후 주사기를 안전하게 수거할 수 있다는 장점은 있으나, 주사기의 사용후 주사바늘을 실린더(101)의 내부로 몰입하기 위하여 플런저(108)의 일측에 형성된 고정돌기(110)에 삽입, 고정되는 연결부재(104)를 별도로 제조하여야 하며 이의 제조시에도 반드시 내측으로 나선부(103)를 형성하여야만 주사바늘 고정구(105)를 회전시켜 연결부재(104)에 고정할 수 있다는 폐단이 있는 것이다.However, the above-mentioned disposable syringe has the advantage that it is possible to safely collect the syringe after use, but the fixed protrusion 110 formed on one side of the plunger 108 to immerse the needle after use of the syringe into the cylinder 101. The connecting member 104 to be inserted and fixed must be manufactured separately, and the manufacturing process of the closed member 103 can be fixed to the connecting member 104 by rotating the needle holder 105 only when the spiral part 103 is formed inward. It is.

따라서 연결부재(104)의 제조시 내측에 형성되는 나선부(103)로 인하여 연결부재(104)를 사출기에서 회전시켜 빼내어야 하는 등의 문제점 있어 생산성이 떨어지는 단점이 있는 것이다.Therefore, due to the spiral portion 103 formed on the inside of the manufacturing of the connecting member 104, there is a problem in that the productivity is low because there is a problem such that the connecting member 104 is removed by rotating in the injection molding machine.

또한 전기한 종래의 주사기는 실린더(101)와 플런저(108), 연결부재(104) 및 주사바늘 고정구(105)등 여러개의 부품으로 제조함으로 제조공정이 복잡하게 되고, 주사기의 조립공정시에도 연결부재(104)에 결합되는 주사바늘 고정구(105)를 반드시 회전시켜야만 연결부재(104)에 결합할 수 있어 주사기의 조립공정을 자동으로 처리하기가 매우 어려운 것이다.In addition, the aforementioned conventional syringe is made of several components, such as the cylinder 101, the plunger 108, the connecting member 104 and the needle fixture 105, the manufacturing process is complicated, even when the assembly process of the syringe is connected The needle fixture 105 coupled to the member 104 must be rotated so as to be coupled to the connecting member 104, so that it is very difficult to automatically process the assembly process of the syringe.

또한 상기한 종래의 주사기는 사용할 때 실린더(101)의 내부에 삽입 결합되는 플런저(108)를 끝까지 즉, 고정돌기(110)가 주사액 통로(106)에 결합되기 직전까지밖에 밀 수밖에 없어 이에 따라 피스톤(107)과 실린더(101)의 간극이 크게 되어 주사액 잔량이 매우 많이 남는 단점이 있는 것이다.In addition, the conventional syringe is forced to push the plunger 108 inserted into the cylinder 101 to the end, i.e., just before the fixing protrusion 110 is coupled to the injection liquid passage 106, so that the piston ( The gap between the 107 and the cylinder 101 is increased, and the amount of the injection liquid remains very large.

본 발명은 이러한 점에 착안하여 실린더의 내벽에 결합되는 연결부재와 주사바늘 고정구를 일체로 형성하여 제조공정 및 조립공정을 간편하게 하여 생산성의 향상은 물론 주사기의 사용시 주사액 잔량이 거의 없는 일회용 주사기를 제공함을 목적으로 한다.The present invention in view of this point to form a connection member and the needle fixture fixed to the inner wall of the cylinder integrally to simplify the manufacturing process and assembly process to improve the productivity as well as to provide a disposable syringe with almost no injection liquid remaining when using the syringe For the purpose.

상기한 목적을 달성하기 위한 수단을 도면을 사용하여 설명하면 다음과 같다.Means for achieving the above object will be described with reference to the drawings.

제1도 내지 제4도에 도시한 바와같이 본 발명의 구성은, 주사바늘 고정구(103)가 연결부재(104)에 나사식으로 결합되어 실린더(104)에 삽입, 결합되는 공지의 안전수거용 일회용 주사기에 있어서, 주사바늘(1)을 일체로 하여 구성되는 주사바늘 고정구(2)의 주사액 통로(15)의 내주면을 호형의 형상으로 구성하여 이에 걸림돌기(9)를 형성하고, 상기 고정구(2)의 외면으로는 일정한 두께로 턱이진 결합돌기(7)를 형성하여 이를 실린더(8)의 내측에 형성된 결합홈(11)에 삽입 결합하고, 상기 실린더(8)의 내부로 삽입되는 플런저(6)의 파지부(17)의 반대편으로는 사방으로 격자상으로 이루어져 일측이 일정한 각도로 경사진 경사면(18)과, 받침턱(13)이 형성된 결합돌출부(4)를 형성하여 이에 단턱(14)과 경사면(18a)이 형성된 피스톤(3)을 삽입하여 구성하고, 상기 받침턱(13)의 일방으로는 주사바늘 고정구(2)의 내면에 형성된 걸림돌기(9)에 대응하여 걸림홈(10)을 형성하여 구성된 것이다.As shown in Figures 1 to 4, the configuration of the present invention, the needle fastener 103 is screwed to the connecting member 104 is screwed into the cylinder 104, the disposable disposable known for safety In the syringe, the inner circumferential surface of the injection passage (15) of the needle holder (2), which is composed of the needle (1) integrally, is formed in the shape of an arc, thereby forming a locking protrusion (9), and the fixture (2) The outer surface of the) to form a jaw engaging projection (7) to a certain thickness and insert it into the coupling groove 11 formed inside the cylinder (8), the plunger 6 is inserted into the cylinder (8) On the opposite side of the holding portion 17 of the) is formed in a grid shape in all directions, one side is inclined at an angle to form an inclined surface 18, and the engaging projection (4) formed with a supporting jaw 13 to the stepped (14) And the piston 3 having the inclined surface 18a formed therein, and the supporting jaw 13 In one direction it is configured to in response to the engaging projection 9 formed on the inner surface of the needle clamp (2) to form a locking groove (10).

도면중 미설명부호 5는 주사바늘(1) 보호캡이고, 12는 절단부이다.In the figure, reference numeral 5 denotes a needle 1 protective cap, and 12 denotes a cut portion.

이와같이 구성된 본 발명은 우선 주사바늘(1)을 일체로 하여 구성된 주사바늘 고정구(2)를 실린더(8)의 내측으로 삽입하여 끼워 넣으면 고정구(2)의 외측에 형성된 결합돌기(7)가 실린더(8)의 내면에 형성된 결합홈(11)에 삽입되면서 주사바늘 고정구(2)가 실린더(8)에 결합되고, 이후 피스톤(3)이 결합된 플런저(6)를 결합하여 사용하면 되는 것이다.In the present invention configured as described above, first, when the needle holder 2 composed of the needle 1 is integrally inserted into and inserted into the cylinder 8, the engaging projection 7 formed on the outside of the fixture 2 is formed into a cylinder ( 8 is inserted into the coupling groove 11 formed on the inner surface of the needle fixture 2 is coupled to the cylinder 8, after which the piston 3 is coupled to use the plunger 6 is combined.

따라서 주사기의 조립시 종래와 같이 주사바늘 고정구(2)를 회전시켜 결합하는 방식이 아니고 단순히 실린더(8)에 삽입한 후 가압하여 결합하므로 결합방식이 간편하여 조립공정을 자동화할 수 있으며, 제조시에도 금형에서 회전시켜 빼지않고 그대로 제조할 수 있으므로 제조공정 및 조립공정이 간편한 것이다.Therefore, when assembling the syringe, it is not a method of rotating and coupling the needle holder 2 as in the prior art, but simply inserting it into the cylinder 8 and then pressing and combining it to simplify the assembly process, thereby automating the assembly process. The manufacturing process and assembly process is simple because it can be manufactured as it is without being rotated out of the mold.

이와같이 조립된 주사기의 사용시 의사나 간호사가 주사액을 실린더(8)에 충진한 후 플런저(6)를 가압하게 되면 주사액이 환자에게 투여되는 것이다.In the case of using the assembled syringe as described above, when the doctor or nurse fills the cylinder 8 and presses the plunger 6, the injection is administered to the patient.

이때 플런저(6)의 일측에 형성된 결합돌출부(4)는 격자상으로 구성되어 일정한 경사면(18)이 형성되어 있고, 결합돌출부(4)에 결합되는 피스톤(3)의 형상도 이에 대응하여 경사면(18a)이 형성되어 있으므로 플런저(6)의 가압시에 피스톤(3)이 외측으로 밀리면서 실런더(8)의 내벽에 완전하게 밀착되므로 주사액이 누출되는 현상이 거의없이 안전하게 주사할 수 있는 것이다.At this time, the coupling protrusion 4 formed on one side of the plunger 6 is formed in a lattice shape, and a constant inclined surface 18 is formed, and the shape of the piston 3 coupled to the coupling protrusion 4 also corresponds to the inclined surface ( Since 18a) is formed, the piston 3 is pushed outward when the plunger 6 is pressed and completely adhered to the inner wall of the cylinder 8, so that the injection liquid can be safely injected with almost no leaking phenomenon.

또한 주사액 통로(15)의 형상은 호형으로 형성되고, 플런저(6)의 선단부는 이에 대응하여 구성되어 있으므로 주사액의 주사시 걸림홈(10)의 외측 선단부가 주사액 통로(15)에 적당히 몰입되므로 주사액 잔량이 거의 없이 안전하게 투여할 수 있는 것이다.In addition, since the shape of the injection passage 15 is formed in an arc shape, and the tip portion of the plunger 6 is configured corresponding thereto, the outer tip portion of the locking groove 10 is appropriately immersed in the injection passage 15 during injection of the injection liquid. It can be safely administered with little remaining amount.

이와같이 환자에게 주사액을 투여한 후 주사기를 수거하고자 하는 경우 플런저(6)를 한번 더 가압하게 되면 플런저(6)에 형성된 걸림홈(10)이 주사바늘 고정구(2)의 주사액 통로(15)에 형성된 걸림돌기(9)에 결합되므로 플런저(6)를 반대 방향으로 당기게 되면 주사바늘 고정구(2)가 플런저(6)와 같은 방향으로 당겨지게 된다.As described above, when the syringe is to be collected after the injection is administered to the patient, when the plunger 6 is pressurized once more, the locking groove 10 formed in the plunger 6 is formed in the injection solution passage 15 of the needle holder 2. When the plunger 6 is pulled in the opposite direction because it is coupled to the locking protrusion 9, the needle holder 2 is pulled in the same direction as the plunger 6.

따라서 주사바늘(1)은 고정구(2)에 일체로 형성되어 있으므로 실린더(8)의 내부로 몰입 되어지고, 플런저(6)를 적당히 당긴후 절단부(12)를 절단하면 주사기를 안전하게 수거할 수 있는 것이다.Therefore, since the needle 1 is integrally formed in the fixture 2, it is immersed in the interior of the cylinder 8, and when the plunger 6 is pulled out appropriately and the cut section 12 is cut, the syringe can be safely collected. will be.

이상과 같이 본 발명은 주사기를 사용한 후 이를 안전하게 폐기 처분할 수 있어 주사기 사용자는 물론이고, 수거자도 2차 감염의 염려가 전혀 없이 안전하게 사용할 수 있는 것이고, 주사바늘이 고정된 고정구를 실린더에 삽입, 결합하는 것만으로 주사기를 조립할 수 있으므로 제조공정 및 조립공정이 간편하여 생산성이 향상되는 등의 효과가 있는 것이다.As described above, the present invention can safely dispose of the syringe after using it, so that the syringe user as well as the collector can be safely used without any concern of the secondary infection.
