현재 사용되고 있는 각종 일회용 주사기는 사용후 주사바늘을 분리시켜 그대로 폐기처분하거나, 주사바늘 부위에 별도의 안전캡을 씌워준 상태로 폐기처분하도록 되어 있었다. 이와 같은 폐기처리 방법에 있어서는, 주사기 수거과정에서 노출상태인 주사바늘에 수거작업자가 불의로 찔리게 되는 일이 빈번하게 발생하고 있으며, 그에따라 주사바늘에 오염되어 있는 각종 세균이 수거작업자에게 전염될 우려가 매우 높았던 폐단이 되고 있는 설정이며, 설사 주사바늘 부위에 별도의 안전캡을 쓰워준 상태로 폐기한다 하더라도 수거과정에서 안전캡이 분리되게 되는일이 빈번하여 완벽한 안전도모 효과를기대할 수 없었던 것이다.Various disposable syringes that are currently being used were to be disposed of as they are disposed of by removing the needle after use, or disposed of with a separate safety cap on the needle. In such a waste disposal method, a collection worker frequently inadvertently sticks to an exposed needle during a syringe collection process, and consequently, various bacteria contaminated with the needle are transmitted to the collection worker. It is a setting that has been a very high concern, and even if it is disposed with a separate safety cap on the needle site, the safety cap is frequently separated during the collection process, and thus the perfect safety promotion effect could not be expected. .

본 고안은 이와같은 종래의 문제점을 감안하여 이를 해소하고자 안출된 것으로, 그 목적은 밀대와 피스톤을 적저어형태의 연구로 조립, 분해가 가능하게 마련하고 상기 밀대의 내부엔 주사바늘 수장실을 갖도록 그 상단에 주사바늘의 몸체구조와 일치되는 형태의 분리수단을 마련하므로서 주사기 실린더 하단의 연결부에 끼워진 상태인 주사바늘을 밀대로 분리시키면서 밀대내부의 주사바늘 수장실에 내입시킨 상태로 안전하게 폐기처분할수 있고 이에따라서 주사바늘에 찔릴우려가 완전히 배제된 상태에서 수거작업자가 안전하게 주사기를 수거할수 있도록 함에 있는 것이다. 이하에서 본 고안을 첨부도면에 의거하여 상세히 설명하면 다음과 같다.The present invention has been devised to solve this problem in view of the conventional problems, and its purpose is to provide assembly and disassembly by studying the shape of the push rod and the piston, and to have a needle compartment inside the push rod. It can be disposed of safely in the state of inserting the needle into the needle chamber inside the rod while separating the needle inserted into the connection part of the lower end of the syringe cylinder with the pusher by providing a separation means in the shape corresponding to the body structure of the needle at the upper end. In this way, the collection worker can safely collect the syringe while being completely excluded from the needle. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Assemble the push rod 3 through 3a) and insert the piston 2, the connecting holes 5 and 3 into the cylinder 1 inner diameter in an integrated state, and then the connecting portion 1a at the bottom of the cylinder 1 ) Is used while the needle (4) is fitted.

이와같은 상태로서 주사기를 사용한 후 주사기를 폐기처분하고자하면, 먼저 실린더(1) 내경에 완전히 내입된 상태인 밀대(3)를 실린더(1) 내경의 걸림돌부(1b)에 연결구(5)가 걸려 정지될때까지 후퇴시킨 다음, 밀대(3)를 축직각 방향으로 밀어 연결구(5)의 결합돌부(5a)에 조립된 상태인 밀대(3)의 결합홈(3a) 개방부축을 통해 간편히 분리시켜 준다.If the syringe is to be discarded after using the syringe in such a state, first, the connecting rod 5 is hooked to the latching portion 1b of the cylinder 1 inner diameter by placing the push rod 3 completely in the cylinder 1 inner diameter. After retreating until stopped, push the push rod (3) in the direction perpendicular to the shaft to be easily separated through the opening groove of the coupling groove (3a) of the push rod (3) in the assembled state (5a) of the connector (5). .

이때 연결구(5)가 실린더(1) 내경의 걸림돌부(1b)에 걸리면서 밀대(3)의 후퇴가 정지되게 되면, 밀대(3)와 연결구(5)의 조립부위가 실린더(1) 외측으로 노출되게 되면서 연결구(5)로 부터의 밀대(3) 분리작업이 자연스럽게 이루어지게 된다.At this time, when the retraction of the pusher 3 is stopped while the connector 5 is caught by the locking protrusion 1b of the inner diameter of the cylinder 1, the assembly portion of the pusher 3 and the connector 5 is exposed to the outside of the cylinder 1. It will be done by separating the push rod (3) from the connector (5) naturally.

이와같은 과정으로 밀대(3)를 분리시킨 다음에는 밀대(3)의 손잡이(3e) 중앙에 위치되는 분리공(3c)을 통해 실린더(1) 연결부(1a)에 끼워진 상태인 주사바늘몸체(4b)가 분리공(3c) 내측에 끼워지는 상태로 밀대(3)를 삽입시키고 이와 동시에 일측방향으로 밀대(3)를 회전시켜 분리공(3c) 내경의 암나사부(3')에 주사바늘몸체(4b) 상단의 돌출단부(4a)가 나사결합되도록 한 후 밀대(3)를 분리시킴으로서, 주사바늘(4)을 밀대(3)의 주사바늘 수장실(3b)에 내입시킨 상태로 간편히 분리시켜 주게되는 것이다.After separating the push rod (3) in this manner, the needle body (4b) is fitted to the connecting portion (1a) of the cylinder (1) through a separation hole (3c) located in the center of the handle (3e) of the push rod (3) ) Is inserted into the separation hole (3c) inside the insertion rod (3) and at the same time by rotating the pusher (3) in one direction by the needle body (3 ') of the female threaded portion (3') of the inner diameter of the separation hole (3c) 4b) After the upper end of the protruding end (4a) is screwed to remove the pusher (3), the needle (4) to be easily separated in the state of injecting needle (3b) in the needle storage chamber of the pusher (3) Will be.

이와같은 주사바늘(4)의 분리상태는 주사바늘몸체(4b) 상단의 돌출단부(4a)가 분리공(3c) 내경의 암나사부(3')에 나사결합된 상태로 밀대(3)의 주사바늘수장실(3b)에 주사바늘(4)이 수장되게 됨으로서 일단 수장된 주사바늘(4)이 외적인 충격에 의해 밀대(3) 외부로 빠져 나올우려가 완벽하게 방지되는 상태로 폐기되게 되어 수거자가 안심하고 수거작업에 임할 수 있게 되는 것이다.The separation state of the needle 4 is such that the protruding end 4a of the upper end of the needle body 4b is screwed to the female screw portion 3 'of the inner diameter of the separation hole 3c. The needle 4 is stored in the needle chamber 3b so that the collected needle 4 is thrown out to the outside of the straw 3 by an external impact and is disposed of in a state of being completely prevented. You will be able to work on the collection with confidence.

한편, 제 3 도 및 제 4 도에 도시된 바와같이 본 고안의 변형실시예는 사용된 주사기에서 전술한 바와같은 과정으로 밀대(3)를 분리한후 상단의 분리공(3h)에 주사바늘몸체(4b)가 끼워지는 상태로 밀대를 삽입하고 이와동시에 일측방향으로 밀대(3)를 비틀면서 회전시켜 주면서 주사바늘(4)을 실린더(1)의 연결부(1a) 상에서 간편히 분리시켜 주게되는 것이다. 이러한 분리과정은 3단형태를 갖는 공지 형태의 주사바늘몸체(4b)가 분리공(3h) 내경의 끼움부(3f)에 긴밀하게 압입된 상태에서 밀대(3)가 비틀리는 형태로 회전되게 됨에따라 분리공(3h) 내경의 걸림돌리(3g)에 주사바늘몸체(4b) 상의 날개편(4c)이 걸리면서 실린더(1)의 연결부(1a)에 끼워진 상태인 주사바늘(4)이 유동되게 됨으로서 주사바늘(4)이 밀대의 주사바늘수장실(3b)에 내입된 상태로 간단히 분리되게 되는 것이다.On the other hand, the modified embodiment of the present invention as shown in Figures 3 and 4 is the needle body in the separation hole (3h) of the upper side after separating the push rod (3) in the same process as described above in the syringe used Inserting the push rod in the state (4b) is inserted and at the same time while rotating the push rod 3 in one direction at the same time, the needle 4 is to be easily separated on the connecting portion (1a) of the cylinder (1). This separation process is to be rotated in the form of twisting the push rod 3 in a state in which the needle body (4b) of the known form having a three-stage form is tightly pressed into the fitting portion (3f) of the inner diameter of the separation hole (3h) Accordingly, the needle 4 in the state of being fitted to the connecting portion 1a of the cylinder 1 flows while the wing piece 4c on the needle body 4b is caught by the locking hole 3g of the inner diameter of the separation hole 3h. The needle (4) is to be separated simply in the state in the needle needle chamber (3b) of the push rod.

이와같은 주사바늘(4)의 분리상태는 3단형태의 주사바늘 몸체(4b)가 분리공(3h) 내경에 압입되어 있는 상태로 밀대(3)의 주사바늘수장실(3b)에 수장되게 됨으로서 이 역시 일단 수장된 주사바늘(4)이 외부로 빠져 나올우려가 없는 상태로 폐기처분되게 되어 수거자가 안심하고 수거작업에 임할 수 있게되는 것이다.The separation state of the needle 4 is such that the needle body 4b of the three-stage shape is stored in the needle storage chamber 3b of the pusher 3 in a state in which the needle body 4b of the three-stage type is press-fitted into the inner diameter of the separation hole 3h. This is also once the collected needle (4) is disposed to be disposed of in a state that there is no concern to escape to the outside, so that the collector can work on the collection work with confidence.

이상에서 상술된 바와같이 본 고안은 종래와 같은 주사기 폐기방법이 내포하고 있던 제반문제점을 완전히 해소한 것으로, 간단한 조작과정으로 밀대 내부에 주사바늘을 내입시킨 상태에서 안전하게 폐기처분하도록함으로서, 수거자가 주사바늘에 불의하게 찔리는 일이 없이 안전하게 수거작업에 임할 수 있게되는 매우 유익한 고안인 것이다.As described above, the present invention completely solves the problems of the conventional syringe disposal method, and by disposing the needle safely in a state in which the needle is inserted into the push rod by a simple operation, the collector collects the injection. It is a very beneficial design that can be safely collected without the needle being unintentionally stuck.
