하우징(110)의 상부측 내부에는 원통형상의 누름부재(130)의 하부측이 삽입되고, 누름부재(130)와 슬리브(120) 사이에는 누름부재(130)를 상측으로 탄성 지지하는 제 1 스프링(141)이 설치된다. 이때, 누름부재(130)는 하우징(110)의 길이방향을 따라 승강가능하게 설치된다. 누름부재(130)의 외주면에 형성된 걸림테(131)는 하우징(110)의 상단부측 내주면에 걸려서 누름부재(130)가 하우징(110)의 상측으로 이탈하는 것을 방지한다. 누름부재(130)의 상부측은 하우징(110)의 상부 외측으로 노출된다.The lower side of the cylindrical pressing member 130 is inserted into the upper side of the housing 110, and between the pressing member 130 and the sleeve 120, a first spring for elastically supporting the pressing member 130 upwards ( 141 is installed. At this time, the pressing member 130 is installed to be elevated in the longitudinal direction of the housing 110. The engaging frame 131 formed on the outer circumferential surface of the pressing member 130 is caught by the inner circumferential surface of the upper end side of the housing 110 to prevent the pressing member 130 from escaping to the upper side of the housing 110. The upper side of the pressing member 130 is exposed to the upper outer side of the housing 110.

누름부재(130)의 하부측 내부에는 피스톤(150)의 상부측이 삽입되고, 피스톤(150)의 하부측은 하우징(110)의 하부측에 위치된다. 그리고, 누름부재(130)의 내부에는 피스톤(150)을 하측으로 탄성 지지하는 제 2 스프링(143)이 설치되고, 피스톤(150)의 외주면에 형성된 지지테(151)와 하우징(110)의 내주면에 형성된 돌출테(113)에는 피스톤(150)을 상측으로 탄성 지지하는 제 3 스프링(145)이 설치된다.The upper side of the piston 150 is inserted into the lower side of the pressing member 130, the lower side of the piston 150 is located on the lower side of the housing (110). In addition, a second spring 143 for elastically supporting the piston 150 is installed inside the pressing member 130, and the support frame 151 formed on the outer circumferential surface of the piston 150 and the inner circumferential surface of the housing 110.

누름부재(130)의 하부측 외주면에는 상호 대향되게 작동홈(133)이 형성되고, 피스톤(150)의 상부측 부위에는 삽입공(151)이 형성된다.An operating groove 133 is formed on the lower outer peripheral surface of the pressing member 130 to face each other, and an insertion hole 151 is formed at an upper side portion of the piston 150.

슬리브(120)의 지지공(121), 누름부재(130)의 작동홈(133) 및 피스톤(150)의 삽입공(151)에는 작동바(160)가 삽입되고, 작동바(160)에 의하여 누름부재(130)와 피스톤(150)이 연동한다.The operation bar 160 is inserted into the support hole 121 of the sleeve 120, the operation groove 133 of the pressing member 130, and the insertion hole 151 of the piston 150, and is operated by the operation bar 160. The pressing member 130 and the piston 150 is interlocked.

피스톤(150)의 동작을 설명한다.The operation of the piston 150 will be described.

최초의 상태에서는, 작동바(160)가 슬리브(120)의 지지공(121)의 상부측에 형성된 걸림돌기(미도시)에 걸려 있다.In the initial state, the operation bar 160 is caught by a locking projection (not shown) formed on the upper side of the support hole 121 of the sleeve 120.

이러한 상태에서, 누름부재(130)를 누르면 누름부재(130)가 하강하게 되고, 누름부재(130)의 하강에 의하여 누름부재(130)의 작동홈(133)의 상면이 작동바(160)에 접촉하여 작동바(160)를 하측으로 누른다. 그러면, 작동바(160)가 상기 걸림돌기로부터 이탈하게 되고, 이로인해 제 2 스프링(143)의 탄성력에 의하여 피스톤(150)이 하강한다.In this state, pressing the pressing member 130, the pressing member 130 is lowered, the upper surface of the operation groove 133 of the pressing member 130 by the lowering of the pressing member 130 to the operation bar 160. Press the operation bar 160 downward in contact. Then, the operation bar 160 is separated from the engaging protrusion, thereby lowering the piston 150 by the elastic force of the second spring 143.

피스톤(150)은 하강한 후, 즉시 제 3 스프링(145)에 의하여 최초의 상태로 복귀되고, 누름부재(130)에 작용하는 외력을 제거하면 제 1 스프링(141)에 의하여 누름부재(130)가 최초의 상태로 복귀된다.The piston 150 is lowered and immediately returned to its initial state by the third spring 145, and when the external force acting on the pressing member 130 is removed, the pressing member 130 is removed by the first spring 141. Returns to the original state.

피스톤(150)은 하강하면서 캡(170)에 내장된 채혈침(180)을 타격한다.The piston 150 descends and strikes the blood collection needle 180 embedded in the cap 170.

본 실시예에 따른 채혈기는 편리한 사용을 위하여 하우징(110)의 하부측에 결합된 캡(170)에 채혈침(180)이 일체로 형성된다.The blood collector 180 according to the present embodiment is integrally formed with the blood needle 180 on the cap 170 coupled to the lower side of the housing 110 for convenient use.

상세히 설명하면, 하우징(110)의 하단부측에는 캡(170)의 상부측 내주면이 결합되고, 캡(170)에는 몸체(181)와 바늘(185)을 가지는 채혈침(180)이 설치된다.In detail, the inner peripheral surface of the upper side of the cap 170 is coupled to the lower end side of the housing 110, and the cap 170 is provided with a blood collection needle 180 having a body 181 and a needle 185.

캡(170)의 내주면에는 캡(170)의 내부를 상하로 구획하는 링형상의 구획테(171)가 형성된다. 몸체(181)의 상부측은 구획테(171)의 내주면을 관통하여 피스톤(150)의 하부측과 인접하여 대향하고, 하부측은 구획테(171)의 하측에 위치된다.On the inner circumferential surface of the cap 170, a ring-shaped partition frame 171 is formed to partition the inside of the cap 170 up and down. The upper side of the body 181 passes through the inner circumferential surface of the partition frame 171 and faces adjacent to the lower side of the piston 150, and the lower side is located below the partition frame 171.

이때, 몸체(181)가 캡(170)의 상측으로 이탈하는 것을 방지하기 위하여, 몸체(181)의 하부측은 상부측 보다 크게 형성되고, 몸체(181)의 하부측 상면은 구획테(171)에 접촉된다.In this case, in order to prevent the body 181 from escaping to the upper side of the cap 170, the lower side of the body 181 is formed larger than the upper side, the upper surface of the lower side of the body 181 to the partition frame 171 Contact.

그리고, 몸체(181)의 하부측과 캡(170) 사이에는 채혈침(180)을 상측으로 탄성 지지하는 탄성부재(190)가 설치되고, 캡(170)의 하면에는 바늘(185)이 통과하는 관통공(173)이 형성된다.In addition, an elastic member 190 is installed between the lower side of the body 181 and the cap 170 to elastically support the blood collection needle 180 upward, and through the needle 185 passes through the lower surface of the cap 170. Ball 173 is formed.

캡(170)은 사출물인데, 캡(170)을 사출하기 위한 금형속에 채혈침(180)을 넣고 캡(170)과 채혈침(180)을 일체로 형성하면 된다.The cap 170 is an injection molded product, and the blood collection needle 180 is inserted into a mold for injecting the cap 170, and the cap 170 and the blood collection needle 180 may be integrally formed.

채혈을 위하여, 캡(170)의 하면을 피부에 접촉시킨 상태에서, 누름부재(130)를 누르면, 전술한 바와 같이, 피스톤(150)이 하강한다. 그러면, 피스톤(150)이 채혈침(180)의 몸체(181)를 타격하게 되고, 이로인해 채혈침(180)이 하강한다. 채혈침(180)이 하강하면, 채혈침(180)의 바늘(185)이 캡(170)의 관통공(173)을 통과하여 피부에 상처를 낸다. 그러면, 피부의 상처난 부위에서 혈액이 나온다.For the blood collection, when the pressing member 130 is pressed while the lower surface of the cap 170 is in contact with the skin, the piston 150 descends as described above. Then, the piston 150 hits the body 181 of the blood collection needle 180, thereby lowering the blood collection needle 180. When the needle 180 is lowered, the needle 185 of the needle 180 passes through the through hole 173 of the cap 170 to injure the skin. Then blood comes out of the wounded area of the skin.

하우징(110)과 캡(170)은 나사결합되는데, 캡(170)의 결합길이를 조절하면 캡(170)의 관통공(173)을 통과하여 캡(170)의 하면 외측으로 돌출되는 바늘(185)의 길이를 조절할 수 있다.The housing 110 and the cap 170 are screwed together, and adjusting the coupling length of the cap 170 passes through the through holes 173 of the cap 170 to protrude outward from the lower surface of the cap 170. ) Length can be adjusted.

본 실시예에 따른 채혈기는 캡(170)에 채혈침(180)이 일체로 형성되므로, 캡(170)을 하우징(110)에 결합한 후, 사용하면 된다. 그리고, 사용한 후에는 하우징(110)으로부터 캡(170)을 분리한 후, 캡(170)을 폐기하면 된다. 따라서, 사용이 대단히 편리하다.Since the blood collector 180 is formed integrally with the cap 170, the blood collector according to the present exemplary embodiment may be used after the cap 170 is coupled to the housing 110. Then, after use, the cap 170 may be discarded after removing the cap 170 from the housing 110. Therefore, it is very convenient to use.

이상에서는, 본 발명의 일 실시예에 따라 본 발명을 설명하였지만, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자가 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 변경 및 변형한 것도 본 발명에 속함은 당연하다.In the above, the present invention has been described in accordance with one embodiment of the present invention, but those skilled in the art to which the present invention pertains have been changed and modified without departing from the spirit of the present invention.
