프라스틱제 주사기의 피스톤(piston)Pistons of plastic syringes

제1도는 본 고안의 사시도이고,1 is a perspective view of the present invention,

제2도는 본 고안의 종단면도이고,2 is a longitudinal sectional view of the present invention,

제3도는 본 고안의 피스톤을 프라스틱제 주사기의 외통속에 삽입한 형태의 종단면도이다.3 is a longitudinal cross-sectional view of the piston of the present invention inserted into the outer cylinder of the plastic syringe.

본 고안은 프라스틱제 주사기의 피스톤(Piston) 앞끝부위에 고무패킹이나 PVC패킹을 부착하지 않고서 사용할 수 있는, 조작이 간편하고, 사용하기 편리하고, 전혀 독성이 없는 안전한 프라스틱제 주사기의 피스톤에 관한 것이다.The present invention relates to a piston of a plastic syringe that is easy to operate, convenient to use, and completely non-toxic, which can be used without attaching a rubber or PVC packing to the front end of a piston of a plastic syringe. .

종래의 프라스틱제 주사기는 사출성형기술상 주사기의 외통의 내경크기가 일정하지 못하고, 뒷부위의 내경이 크고 앞부위로 갈수록 내경이 점차 작아지게 데파(Depper)가 되어있음으로, 유리제 주사기의 피스톤과 같이 외경을 일정하게 고정되게 만든 프라스틱제 피스톤으로서는 그 기능을 할 수가 없다.Conventional plastic syringes have a constant inner diameter of the outer cylinder of the syringe due to the injection molding technology, and the inner diameter of the rear portion is large, and the inner diameter gradually decreases toward the front portion, so that the inner diameter is gradually reduced, such as the piston of the glass syringe. Plastic pistons whose outer diameters are fixed at a fixed level cannot function.

그러므로 지금까지의 프라스틱제 주사기의 피스톤은, 피스톤측 앞끝부위에 별도로 고무패킹이나 PVC패킹을 부착하여 그 패킹의 신축작용을 이용하여 주사기의 피스톤으로 사용하여왔다.Therefore, the piston of the plastic syringe so far has been used as a piston of the syringe by attaching rubber packing or PVC packing to the front end of the piston side by using the elasticity of the packing.

이와 같이 종래의 프라스틱제 주사기의 피스톤은, 피스톤축 앞끝부위에 고무패킹이나 PVC패킹을 부착하여야 하는 작업상의 번잡이 따르고, 또 그 패킹값만치 가격이 더 많이 소요될뿐만 아니라 더욱이 고무패킹이나 PVC패킹을 만드는 고무나 PVC재질자체에는 인체에 절대 유해한 각종독성이 포함되어 있음으로써, 의료기구인 주사기의 피스톤으로서는 적합하지 못한 결정적인 결점을 가지고 있었다.In this way, the piston of a conventional plastic syringe follows the cumbersome work of attaching rubber packing or PVC packing to the front end of the piston shaft, and the packing value is more expensive, and moreover, rubber packing or PVC packing is required. The rubber or PVC material itself contains various toxic substances that are absolutely harmful to the human body.

본 고안은 전혀 인체에 유해한 독성이 없는 폴리에틸렌(Polyethlene), 또는 폴리푸로필렌(Polypropylene)을 사용하여 도면에 표현한 바와 같이 피스톤축(1) 앞끝부위(2)의 주위에 홈(3)을 만들고, 그 홈(3) 바깥쪽의 주위가장자리테(4)의 밑부분(4)은 얇게 하고, 윗부분(4')은 밖으로 돌출한 형태로 만들며 그 주위 가장자리테(4)의 윗부분(4')이 직경크기는, 사용하는 주사기의 외통(5)이 내경(5')보다 약간 더 크게 만든다.The present invention makes a groove (3) around the front end portion (2) of the piston shaft (1) as shown in the drawings using polyethylene (Polyethlene) or polypropylene (Hypotoxic), which is not harmful to the human body at all, The bottom part 4 of the peripheral edge frame 4 outside the groove 3 is made thin, and the upper part 4 'is made to protrude outward, and the upper part 4' of the peripheral edge frame 4 is The diameter size makes the outer cylinder 5 of the syringe used slightly larger than the inner diameter 5 '.

이와 같이 만들어진 프라스틱제 주사기의 피스톤을, 주사기의 외통(5) 속으로 삽입하여 전후진 시킬때, 피스톤축(1)의 앞글부위(2)의 홈(3)의 바깥쪽의 주위가장자리테(4)이 윗부분(4')은, 사용하는 주사기의 외통(5)의 내경(5') 크기에 따라서 홈(3) 공간과 주위가장자리테(4)의 밑부분(4')이 윗부분(4')보다 얇게 되어있기 때문에 쉽게 오므라지며, 또한 프라스틱재질의 환원작용으로 오므려졌든 부분이 쉽게 환원작용으로 퍼지게 되면서 주사기의 외통(5)의 내경크기에 따라 내벽(5')에 빈틈없이 밀접하게 됨으The peripheral edge of the outer edge of the groove 3 of the front portion 2 of the piston shaft 1 when the piston of the plastic syringe made in this way is inserted into the outer cylinder 5 of the syringe and moved forward and backward. The upper part 4 'is the upper part 4' of the groove 3 space and the peripheral edge 4 'according to the size of the inner diameter 5' of the outer cylinder 5 of the syringe to be used. Because it is thinner than), it is easily retracted, and the part that is enclosed by the reducing action of the plastic material is easily spread by the reducing action, and closely close to the inner wall 5 'according to the inner diameter size of the outer cylinder 5 of the syringe.

위와 같이 본 고안의 프라스틱제 주사기의 피스톤은, 종래의 프라스틱제 주사기의 피스톤과는 달리, 피스톤축(1)의 앞끝부분(2)에 독성이 포함되어 있는 고무패킹이나 PVC패킹을 별도로 부착하지 않음으로, 독성이 없어서 안전하고 생산이간편하고 생산가가 저렴하고 사용하기 편리한 프라스틱제 주사기의 피스톤이다.As described above, the piston of the plastic syringe of the present invention, unlike the piston of the conventional plastic syringe, does not separately attach a rubber packing or PVC packing that contains toxic to the front end portion (2) of the piston shaft (1) It is a piston of a plastic syringe, which is safe, easy to produce, inexpensive and easy to use because it is not toxic.
