도 1 내지 도 7에 도시된 바와 같이, 본 발명의 일 실시예에 따른 무동력 피스톤 가압보조장치는, 피스톤 가압대(22)를 구비한 주사기(2)를 장착하여 주사하는 가이드부재(100)와, 상기 가이드부재(100)가 내부에 결합되는 하우징(500)을 포함하여 구성된다. 1 to 7, a non-powered piston pressure assisting apparatus according to an embodiment of the present invention includes a guide member 100 for mounting and scanning a syringe 2 having a piston presser 22, And a housing 500 to which the guide member 100 is coupled.

또는 가이드부재(100)만 단독으로도 사용될 수 있다. Or only the guide member 100 can be used alone.

도 1을 참조하면, 상기 가이드부재(100)는, 일측에는 주사기(2)의 환턱(24)이 끼워지는 개구공(420)이 형성되고, 양측면에 길이방향으로 가이드공(45)이 형성되며, 내부에 공간이 형성되고, 내면에는 길이방향으로 제1,2랙기어(43,44)가 형성된 본체(4); 제1,2랙기어(43,44)에 결합되어 주사기(2)의 피스톤 가압대(22)를 가압하는 보조가압부를 포함한다. Referring to FIG. 1, the guide member 100 has an opening hole 420 through which the tip 24 of the syringe 2 is inserted, and guide holes 45 are formed on both sides of the guide member 100 in the longitudinal direction A main body 4 having a space formed therein and having first and second rack gears 43 and 44 formed on its inner surface in the longitudinal direction; And an auxiliary pressing portion which is coupled to the first and second rack gears 43 and 44 and presses the piston pressing portion 22 of the syringe 2.

상기 보조가압부는, 제1랙기어(43)에 결합되는 피니언기어(62)가 양측면에 형성된 축(68)에 결합되고, 상기 축(68)의 단부가 가이드공(45)에 삽입되어 가이드공(45)을 따라 전진하면서 주사기(2)의 피스톤 가압대(22)를 가압하는 가압레버(6); 피니언기어(62)와 일체로 결합되며 가압레버(6)의 회전시 피니언기어(62)가 제1랙기어(43)를 따라 회전되면서 상기 가압레버(6)를 전진구동시켜 피스톤 가압대(22)를 밀도록 하고, 가압레버(6)가 원위치되도록 아이들링 작용하는 원웨이베어링(7); 피니언기어(62)가 결합된 축(68)에 결합되어 제2랙기어(44)에 걸림 고정되는 록킹부재(8);을 포함하여 이루어진다.The auxiliary pushing portion is engaged with a shaft 68 formed on both sides of a pinion gear 62 coupled to the first rack gear 43 and an end of the shaft 68 is inserted into the guide hole 45, A push lever 6 for pushing the piston pressurizing belt 22 of the syringe 2 while advancing along the piston 45; The pinion gear 62 is integrally coupled to the pinion gear 62 and rotates the pinion gear 62 along the first rack gear 43 when the pressure lever 6 is rotated so as to forwardly drive the pressure lever 6, Way bearing 7 for pushing the pressing lever 6 in an idling state so that the pressing lever 6 is in the home position; And a locking member 8 coupled to the shaft 68 to which the pinion gear 62 is coupled and fixed to the second rack gear 44.

본체(4)는 대략 직사각형의 형상이며, 전면에 전면걸림부재(42)가 형성되고, 양측 장변에는 각기 길이방향으로 가이드공(45)이 형성되고 내부에는 가압레버(6)가 이동될 수 있도록 제1,2랙기어(43,44)가 형성된다. The main body 4 has a substantially rectangular shape and is provided with a front latching member 42 on its front side and a guide hole 45 formed in both longitudinal sides thereof in the longitudinal direction so that the push lever 6 can be moved The first and second rack gears 43 and 44 are formed.

전면걸림부재(42)에는 주사기(2)의 몸통이 끼워질 수 있도록 개구공(420)이 형성된다. An opening hole 420 is formed in the front latching member 42 so that the body of the syringe 2 can be inserted.

주사기(2)의 크기에 따라 몸통 직경이 상이하므로 본 실시예의 다른 형태로는 전면걸림부재(42)의 개구공(420)의 크기를 조절할 수 있는 가변형 전면걸림부재(42)를 포함한다.Since the body diameter varies depending on the size of the syringe 2, another type of the present embodiment includes a variable front engaging member 42 that can adjust the size of the opening hole 420 of the front engaging member 42.

도 5를 참조하면, 가변형의 전면걸림부재(42)는 개구공(420)의 간격이 조절되도록 좌우에 슬라이드되게 결합되는 제1,2걸림편(421,422)을 포함하고, 제1,2걸림편(421,422)은 상반되게 좌우로 슬라이드되면서 간격이 조절되도록 한 것이다.5, the variable front engaging member 42 includes first and second engaging pieces 421 and 422 slidably coupled to the left and right so as to adjust the distance between the opening holes 420, (421, 422) are slid to the left and right in opposite directions to adjust the gap.

제1,2걸림편(421,422)은 외측에 버튼(423)이 구비되고, 버튼(423)은 고정력을 발휘하는 스토퍼작동을 하게 된다. 버튼(423)을 눌렀을때는 고정 상태가 해제됨으로써 제1,2걸림편(421,422)이 각기 좌우로 상반되게 이동될 수 있는 것이다. The first and second engaging pieces 421 and 422 are provided with a button 423 on the outer side and the button 423 is operated by a stopper that exerts a fixing force. When the button 423 is depressed, the fixed state is canceled so that the first and second latching pieces 421 and 422 can be moved in opposite directions to each other.

다시 도 2를 참조하면, 상기 가압레버(6)는 호형의 판상으로 형성되며, 엄지의 곡률을 감안하여 후방을 향해 휘어진 형상으로 이루어지고, 양측으로 축(68)이 형성된다. Referring again to FIG. 2, the pressing lever 6 is formed in an arc-shaped plate shape and is bent in a rearward direction in consideration of the curvature of the thumb, and the shaft 68 is formed on both sides.

제1랙기어(43)에 결합되는 피니언기어(62)가 양측면에 형성된 축(68)에 결합되고, 상기 축(68)의 단부가 가이드공(45)에 삽입되어 가이드공(45)을 따라 전진하면서 주사기(2)의 피스톤 가압대(22)를 가압하게 되는 것이다. A pinion gear 62 coupled to the first rack gear 43 is coupled to a shaft 68 formed on both sides and an end of the shaft 68 is inserted into the guide hole 45, And presses the piston presser 22 of the syringe 2 while advancing.

원웨이베어링(7)은 일방향으로만 회전할때에는 피니언기어(62)와 일체로 회전됨으로써 피니언기어(62)가 회전된 거리만큼 전진할 수 있다. 이러한 전진은 가압레버(6)가 전진하는 거리가 된다. When the one-way bearing 7 rotates only in one direction, the one-way bearing 7 can be rotated by the rotation of the pinion gear 62 by being rotated integrally with the pinion gear 62. This advancement becomes the distance at which the pressure lever 6 advances.

이후 가압레버(6)에 대한 가압력이 제거되면 토션스프링(69)의 복원력에 의해 가압레버(6)가 후방으로 회전되면서 원위치되는데 이 과정에서 원웨이베어링(7)은 아이들링 회전되므로 피니언기어(62)는 회전되지 않는다.
