본 고안은 채혈용 주사기에 관한 것으로, 특히 일정량의 혈액을 채혈한 후 연질고무재의 피스톤헤드에서 피스톤을 간단히 분리시킬 수 있도록 하여 채혈된 피를 별도의 시험관에 옮길 필요없이 주사기의 실린더를 직접 시험관으로 이용하도록 함으로서 취급과정을 간소화 함은 물론 혈액을 옮기는 과정에서의 오염을 방지하도록 함과 동시에 실린더의 플랜지에 적정형상을 갖는 하단캡이 분리가능한 상태로 연결 부착된 별도의 상단캡을 삽설하여 채혈후에 실린더의 유입구와 피스톤 헤드가 위치되는 실린더 상단부에 간편히 결합시켜 주도록 함으로서 실린더 내부가 밀폐상태로 유지되도록 하여 이동이나 보관시 실린더 내부에 채혈된 상태인 혈액이 유출되거나 변질되는 것을 완벽하게 방지하도록 한 채혈용 주사기에 관한 것이다.The present invention relates to a syringe for blood collection, and in particular, after a certain amount of blood has been collected, the piston can be easily separated from the piston head of a soft rubber material, so that the cylinder of the syringe is directly transferred to the test tube without having to transfer the collected blood to a separate test tube. By simplifying the handling process as well as preventing contamination in the process of transferring blood, and inserting a separate top cap attached to the flange of the cylinder in a detachable state with a lower cap having a proper shape after the blood collection By simply coupling the inlet of the cylinder and the upper part of the cylinder where the piston head is located, the inside of the cylinder is kept closed so that the blood that is collected inside the cylinder during the movement or storage is completely prevented from leaking or altering. Relates to a syringe.
종래에도 혈액을 채혈한 후 피스톤헤드(22)가 실린더(24)의 상단부에 위치된 상태에서 피스톤(23)의 중간부위를 절단하여 실린더(24)내에 혈액을 보관하도록 한 예가 있었으나, 다량의 혈액을 채혈하는 경우에는 절단된 잔여피스톤(23)부위가 실린더(24)의 상부로 노출되게 되어 취급 및 보관에 어려움이 따랐음은 물론 피스톤(23)을 절단하기 위해 일측방으로 힘을 가하는 과정에서 무리한 힘을 가하게되면 실린더(24)까지 파손될 우려가 있는등의 문제점이 있었다.Conventionally, after the blood was collected, there was an example in which the middle portion of the piston 23 was cut and the blood was stored in the cylinder 24 while the piston head 22 was positioned at the upper end of the cylinder 24. In the case of collecting blood, the cut residual piston 23 is exposed to the upper part of the cylinder 24, which is difficult to handle and store, as well as in the process of applying a force to one side to cut the piston 23. If an excessive force is applied, there is a problem that the cylinder 24 may be damaged.
또한 채혈후에는 주사기(21)의 유입공(25)을 별개의 마개로 밀폐해 주어야만 하는 관계로 마개의 보관 및 관리가 번거로웠던 문제점이 노출되고 있었다.In addition, since the inflow hole 25 of the syringe 21 should be sealed after the blood collection, the problem of cumbersome storage and management was exposed.
본 고안은 이와같은 문제점을 감안하여 안출한 것으로, 피스톤과 피스톤헤드를 상호 분리형성하여 각기 분해시킬 수 있도록 하고, 실린더의 상단부에는 별도 형성되는 상단캡을 조립결합함과 동시에 그 상단캡에는 분리가능한 상태로서 적정형상의 하단캡을 연결부착하여 채혈후에는 하단캡을 간단히 분리한후 실린더의 유입구에 결합 시켜주면서 실린더내부를 밀폐시키도록 함으로서, 그 취급과 보관이 간편하면서도 채혈된 오염을 효과적으로 방지하면서 사용할 수 있는 채혈용 주사기를 제공하고자 하는데 목적이 있는 것으로, 그 구성 및 작용효과를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.The present invention has been devised in view of the above problems, so that the piston and the piston head can be separated from each other to form a separate, and the upper cap of the cylinder can be separated and assembled at the same time as the upper cap is separately assembled. As it is, by attaching the lower cap of proper shape and connecting the inlet of the cylinder, the lower cap is simply removed after the blood collection, and the inside of the cylinder is sealed while the handling and storage is easy. It is an object of the present invention to provide a blood collection syringe that can be used, and its configuration and effect will be described in detail based on the accompanying drawings.
실린더(1)내에서 피스톤(2)과 피스톤헤드(3)가 상,하작동하도록 된 통상의 주사기(1a)에 있어서, 실린더(1)내벽의 상단부에는 걸림돌기(4)를, 외벽상단에는 끼움돌기(4a)를 각각 돌출형성하여 실린더(1)를 이루고, 피스톤(2)의 하단부에는 원추형의 결합돌기(5')를 형성하여 피스톤(2)을 이룸과 동시에 연질고무재의 피스톤헤드(3)에는 절결부(5")를 갖는 결합공(5)을 형성하여 이룸으로서 피스톤(2)과 피스톤헤드(3)의 분해결합이 자유롭게 이루어지도록 하며, 중앙부에 적정직영의 중공부(6)가 형성됨과 동시에 하단에 나선(8a)을 갖는 끼움부(8)가 연장형성되어 이루어진 적정형상의 상단캡(7)을 실린더(1)외벽상단의 끼움돌기(4a)에 조립결합하되 상단캡(7)에는 내부에 삽입돌기(9") 및 속마개(9')가 순차적으로 형성되어 이루어진 반구형의 하단캡(9)을 절단부(10)로서 연결부착하여 구성된 것으로, 미설명부호 11은 주사바늘을, 12는 실린더(1)의 유입공을 각각 나타낸 것이다.In a conventional syringe (1a) in which the piston (2) and the piston head (3) are operated up and down in the cylinder (1), a locking projection (4) is provided at the upper end of the inner wall of the cylinder (1), and at the upper end of the outer wall. The fitting protrusion 4a is formed to protrude to form the cylinder 1, and the lower end of the piston 2 forms a conical engaging protrusion 5 'to form the piston 2 and at the same time the piston head 3 of the soft rubber material. ) Forms a coupling hole (5) having a cutout (5 ") so that the disassembly and coupling of the piston (2) and the piston head (3) is freely made, the hollow portion 6 of the proper direct At the same time, the upper end cap 7 of a suitable shape formed by extending the fitting portion 8 having the spiral 8a at the bottom thereof is assembled to the fitting protrusion 4a on the outer wall of the cylinder 1, but the upper cap 7 ) Has a hemispherical lower end cap 9 which is formed by sequentially forming an insertion protrusion 9 " and an inner plug 9 " The reference numeral 11 denotes a needle and 12 denotes an inlet hole of the cylinder 1.
이와같은 구성으로 이루어진 본 고안의 작용 및 효과를 상술하면 다음과 같다.Referring to the operation and effects of the present invention made of such a configuration as follows.
본 고안의 주사기(1a)로서 적정량의 혈액을 채혈한후 피스톤 헤드(3)가 실린더(1) 내경상단부의 걸림돌기(4)에 걸림과 동시에 상단캡(7)의 중공부(6)에 걸려 저지될때까지 피스톤(2)을 계속적으로 상승시킨다음 피스톤(2)을 일측으로 약간 밀면서 잡아당겨 주게되면 연질고무재인 피스톤헤드(3)의 절결부(5")가 벌어지게 되면서 결합공(5)에 삽입되어 있던 피스톤(2)의 결합돌기(5')가 이탈되게 되어 피스톤헤드(3)에서 피스톤(2)이 간단히 분리되게 된다.After collecting the appropriate amount of blood with the syringe 1a of the present invention, the piston head 3 is caught by the locking projection 4 of the upper end of the inner diameter of the cylinder 1 and simultaneously caught by the hollow 6 of the upper cap 7. The piston (2) is continuously raised until it is blocked, and when the piston (2) is pushed slightly to one side and pulled out, the cutout part 5 "of the piston head 3, which is a soft rubber material, is opened, and the coupling hole 5 is opened. The engaging projection 5 'of the piston 2 inserted into the main body is separated and the piston 2 is simply separated from the piston head 3.
이와같은 상태에서 실린더(1)외벽상단의 끼움돌기(4a)에 조립결합된 상태인 상단캡(7)에 절단부(10)로서 연결부착된 상태인 하단캡(9)을 간단히 떼어낸후 실린더(1)의 유입공(12)에 결합시키게 되면 삽입돌기(9") 및 속마개(9')가 유입공(12)의 내, 외경상에 긴밀하게 끼워지면서 실린더(1)의 내부를 완전히 밀폐시키게 되어 실린더(1)에 채혈된 혈액을 밀폐상태로 보관하게 되는 것이다.In such a state, the lower cap 9, which is attached to the upper cap 7, which is assembled and fitted to the fitting protrusion 4a on the upper end of the outer wall of the cylinder 1, as the cutting portion 10, is simply removed, and then the cylinder 1 When coupled to the inlet hole 12 of the inlet), the insertion protrusion 9 "and the fastener 9 'are tightly fitted on the inner and outer diameters of the inlet hole 12 to completely seal the inside of the cylinder 1. The blood collected in the cylinder 1 is to be kept in a sealed state.
이상에서 상술된 바와같은 본 고안은 피스톤(2)과 피스톤헤드(3)를 분리구성하여 상호 분해할 수 있도록 함으로서 그취급 및 보관이 용이하게 됨은 물론 실린더를 직접 시험관으로 이용할 수 있도록 함으로서, 취급과정을 단순화 함과 동시에 혈액의 오염을 효과적으로 방지할 수 있게 되고, 실린더(1)외벽상단의 끼움돌기(4a)에 끼움부(8)로서 조립결합되는 상단캡(7)상에 하단캡(9)을 일체로서 연결부착하여 종래와 같이 별개의 마개를 보관 관리해야만하는 번거로움이 없게 되는 유익하고도 실용적인 고안인 것이다.The present invention as described above, by separating the piston (2) and the piston head (3) to be mutually disassembled to facilitate the handling and storage, as well as to use the cylinder directly as a test tube, the handling process Simultaneously, it is possible to effectively prevent blood contamination, and the lower cap 9 on the upper cap 7 assembled as the fitting portion 8 to the fitting protrusion 4a on the outer wall of the cylinder 1. It is an advantageous and practical design that there is no hassle of having to keep separate plugs as in the prior art by attaching and attaching them as one body.
