도 1 내지 도 7을 참조하면, 본 발명에 의한 주사바늘 처리기(100)는 본체(110), 바늘 안내부재(120), 구동부재(130), 종동부재(140), 구동력 전달부재(150), 제1 텐션부재(160) 및 제2 텐션부재(170)를 포함한다.1 to 7, the injection needle processing machine 100 according to the present invention includes a main body 110, a needle guide member 120, a driving member 130, a driven member 140, and a driving force transmission member 150. And a first tension member 160 and a second tension member 170.

이때, 본 발명의 주사바늘 처리기(100)에 의해 분리되는 주사바늘은 치과용 또는 채혈용 등에 적용될 수 있다. 즉, 주사기(10)와 주사바늘(14)을 연결하는 부분이 나사식(회전형)으로 구비되므로 치과 마취용과 버큐테이너 홀더용 등과 같은 회전형 체결식에 모두 적용 가능하다.At this time, the injection needle separated by the injection needle treatment device 100 of the present invention may be applied to dentistry or blood collection. That is, since the portion connecting the syringe 10 and the needle 14 is provided in a screw type (rotary type), it can be applied to both a rotary type fastening type such as for dental anesthesia and a vertebral container holder.

본체(110)는 도 1에 도시된 바와 같이 내부에 바늘 안내부재(120), 구동부재(130), 종동부재(140), 구동력 전달부재(150), 제1 텐션부재(160) 및 제2 텐션부재(170)를 지지하는 구성이다.As shown in FIG. 1, the main body 110 includes a needle guide member 120, a driving member 130, a driven member 140, a driving force transmission member 150, a first tension member 160 and a second It is a configuration to support the tension member 170.

이때, 도 2를 참조하면, 주사바늘(14)은 주사기(10)의 주사기 몸체(12) 하단에 나선 체결되도록 내주면에 나선이 형성된 연결구(16)의 중심부에 고정된다. 따라서, 본 발명에 의한 주사바늘 처리기(100)는 주사바늘(14)이 고정된 연결구(16)를 회전시켜 주사기 몸체(12)에서 분리되게 한다.In this case, referring to FIG. 2, the injection needle 14 is fixed to the center of the connector 16 having a spiral formed on the inner circumferential surface so as to be spirally fastened to the lower end of the syringe body 12 of the syringe 10. Accordingly, the injection needle treatment device 100 according to the present invention rotates the connector 16 to which the injection needle 14 is fixed to be separated from the syringe body 12.

바늘 안내부재(120)는 도 1 내지 도 3에 도시된 바와 같이 주사바늘(14)이 동일 높이에 안착되도록 주입구(122)가 형성된다. 즉, 주입구(122)에 삽입된 주사바늘(14)의 연결구(16) 단부(하부)가 항시 구동회전체(132)와 종동회전체(142)의 사이 높이에 위치되도록 하는 것이다.The needle guide member 120 has an injection hole 122 formed so that the injection needle 14 is seated at the same height as shown in FIGS. 1 to 3. That is, the end (lower) of the connector 16 of the injection needle 14 inserted into the injection port 122 is always positioned at a height between the driving rotation body 132 and the driven rotation body 142.

더욱이, 주입구(122)의 하부에는 감지부(S1)가 설치되어 주사바늘(14)이 진입하면서 연결구(16)를 감지부(S1)에서 감지한 후 구동모터(138)에 구동신호를 출력하도록 하고, 주사바늘(14)의 연결구(16)가 감지되지 않으면 구동모터(138)에 구동신호를 출력 정지하도록 한다.Moreover, a sensing unit S1 is installed under the injection port 122 so that the connection port 16 is sensed by the sensing unit S1 as the injection needle 14 enters, and then a driving signal is output to the driving motor 138. And, when the connector 16 of the injection needle 14 is not detected, the driving signal is output to the driving motor 138 to stop.

한편, 도 7을 참조하면, 바늘 안내부재(120)는 주사바늘(14)의 연결구(16) 길이가 달라도 연결구(16)와 구동부재(130) 및 종동부재(140)와의 위치를 조절할 수 있다. 이를 위해 바늘 안내부재(120)의 주입구(122) 내주면에 나사산(122a)을 형성하고 나사산(122a)에 나선 체결되도록 외주면에 나사산이 형성된 승강부(124)를 구비한다. 여기서, 승강부(124)는 중심부에 주사바늘(14)이 통과하도록 관통홀(124a)이 관통 형성되고, 관통홀(124a)과 이웃한 상면에 승강부(124)의 높낮이 조절을 위해 승강부(124)를 회전시킬 수 있도록 홈(126)이 형성된다. 따라서, 연결구(16)의 길이가 긴 경우 승강부(124)를 상승시키게 되고, 연결구(16)의 길이가 짧은 경우 승강부(124)를 하강시키게 된다.On the other hand, referring to FIG. 7, the needle guide member 120 may adjust the position of the connector 16 and the driving member 130 and the driven member 140 even if the length of the connector 16 of the injection needle 14 is different. . To this end, a screw thread 122a is formed on the inner circumferential surface of the injection port 122 of the needle guide member 120, and an elevating portion 124 having a thread formed on the outer circumferential surface so as to be helically fastened to the thread 122a is provided. Here, the elevating portion 124 is formed through a through hole (124a) so that the injection needle 14 passes through the center, and the elevating portion to adjust the height of the elevating portion 124 on the upper surface adjacent to the through hole (124a) The groove 126 is formed so that the 124 can be rotated. Therefore, when the length of the connector 16 is long, the elevating portion 124 is raised, and when the length of the connector 16 is short, the elevating portion 124 is lowered.

구동부재(130)는 도 1 내지 도 4에 도시된 바와 같이 바늘 안내부재(120)와 이격된 하방향 일측에 구비되어 주사바늘(14)의 연결구(16) 일측에 회전력을 발생시키며, 구동회전체(132), 구동력 전달부재 연결부(134), 지지부(136), 감지부(S2) 및 구동모터(138)를 포함한다.The driving member 130 is provided on one side in the downward direction spaced apart from the needle guide member 120 as shown in FIGS. 1 to 4 to generate a rotational force on one side of the connector 16 of the injection needle 14, and (132), a driving force transmission member connection part 134, a support part 136, a sensing part (S2) and a driving motor (138).

구동회전체(132)는 기어 형상으로 형성되되, 종동회전체(142)와 함께 구동되면서 주사바늘(14)의 연결구(16)를 빠르고 쉽게 분리하도록 주사바늘(14)의 연결구(16) 일측에 밀착되며, 외주면 일부에 홈부(132a)가 형성된다.The driving rotation body 132 is formed in a gear shape, and while being driven together with the driven rotation body 142, it is in close contact with one side of the connector 16 of the injection needle 14 to quickly and easily separate the connector 16 of the injection needle 14 And, a groove portion (132a) is formed in a portion of the outer peripheral surface.

이때, 홈부(132a)는 구동회전체(132)의 구동 시작 또는 구동 종료시 바늘 안내부재(120)의 하측에 위치되도록 구동모터(138)에 의해 위치가 제어되어, 주사바늘(14)을 바늘 안내부재(120)에 삽입할 때 주사바늘(14)의 연결구(16)가 간섭받지 않으면서 구동회전체(132)와 종동회전체(142)의 사이에 위치되도록 형성된다.At this time, the position of the groove part 132a is controlled by the driving motor 138 so that it is located under the needle guide member 120 when the driving rotation body 132 starts or ends, so that the injection needle 14 is connected to the needle guide member. When inserted into 120, the connector 16 of the injection needle 14 is formed to be positioned between the driving rotation body 132 and the driven rotation body 142 without interference.

더욱이, 구동회전체(132)는 기어이의 단부 특히, 상단 가장자리가 경사지게 형성됨으로써 주사바늘(14)의 연결구(16)에 닿는 면적을 최소화하면서 구동력 전달이 가능해진다.In addition, the driving rotation body 132 has an end portion of the gear teeth, in particular, an upper edge of which is formed to be inclined, so that a driving force can be transmitted while minimizing an area that contacts the connector 16 of the injection needle 14.

한편, 구동회전체(132)는 기어 형상으로 형성되는 것으로 예시하였으나, 이에 한정하지 않고 홈 모양이 없는 우레탄 소재 등으로도 구현 가능하다.Meanwhile, the driving rotating body 132 is illustrated as being formed in a gear shape, but is not limited thereto, and may be implemented with a urethane material having no groove shape.

구동력 전달부재 연결부(134)는 구동회전체(132)와 동심을 갖으면서 하부에 형성되어 구동력 전달부재(150)의 내면 일단이 걸리도록 구비된다. 이때, 구동력 전달부재 연결부(134)는 외주면에 홈이 방사상으로 형성되어 구동력 전달부재(150)가 잘 회전될 수 있게 한다.The driving force transmission member connection part 134 is formed at a lower portion while being concentric with the driving rotation body 132 and is provided to catch one end of the inner surface of the driving force transmission member 150.

한편, 도 8을 참조하면, 구동회전체(132)와 종동회전체(142)는 원형의 기어 형상으로 형성되는 앞선 실시예와 달리 다른 실시예에서는 구동회전체(132')와 종동회전체(142')가 랙 기어 형상으로 형성 가능하다.On the other hand, referring to FIG. 8, the driving rotation body 132 and the driven rotation body 142 are formed in a circular gear shape, unlike the previous embodiment, in other embodiments, the driving rotation body 132' and the driven rotation body 142' ) Can be formed in a rack gear shape.

이렇게, 구동회전체(132')와 종동회전체(142')는 기어이가 서로 대향된 위치에 형성되면서 그 사이에 주사바늘(14)이 고정된 연결구(16)가 외주면 양쪽에 밀착되게 위치되므로 각각의 구동부(도면에 미도시)에 의해 구동회전체(132')와 종동회전체(142')가 서로 반대 방향으로 교번 직선 왕복 운동하도록 제어하여 직선 왕복 운동을 통해 연결구(16)에 회전력을 발생시키게 된다.In this way, the driving rotation body 132 ′ and the driven rotation body 142 ′ are formed at positions opposite to each other, and the connector 16 having the injection needle 14 fixed therebetween is located in close contact with both sides of the outer circumferential surface. By controlling the drive rotor 132' and the driven rotor 142' to alternate linearly reciprocating movements in opposite directions by the driving unit (not shown in the drawing) of, to generate a rotational force in the connector 16 through a linear reciprocating movement. do.

이와 같이 본 발명에 의한 주사바늘 처리기(100)의 작동 과정을 설명하면 다음과 같다.In this way, the operation process of the injection needle processor 100 according to the present invention will be described as follows.

먼저, 치과용 주사기(10)를 바늘 안내부재(120)의 주입구(122)에 삽입하면 주사바늘(14)이 고정된 연결구(16)가 주입구(122)의 저면에 밀착된다. 이때, 구동부재(130)의 구동회전체(132)에 형성됨 홈부(132a)가 바늘 안내부재(120)의 주입구(122) 하측 동일 수직선상에 위치된 상태이다.First, when the dental syringe 10 is inserted into the injection port 122 of the needle guide member 120, the connector 16 to which the injection needle 14 is fixed is in close contact with the bottom surface of the injection port 122. At this time, the groove portion 132a formed in the driving rotating body 132 of the driving member 130 is located on the same vertical line under the injection hole 122 of the needle guide member 120.

다음으로, 주사바늘(14)의 연결구(16)가 주입구(122)의 저면에 안착되면, 이를 구동회전체(132)에 설치된 감지부(S)가 이를 감지하여 구동모터(138)에 구동신호를 출력하게 된다.Next, when the connector 16 of the injection needle 14 is seated on the bottom of the injection port 122, the sensing unit S installed in the driving rotating body 132 senses it and transmits a driving signal to the driving motor 138. Will be printed.

다음으로, 구동모터(138)가 구동되면 구동력이 구동력 전달부재(150)를 통해 구동부재(130)의 구동력 전달부재 연결부(134)에서 종동부재(140)의 구동력 전달부재 연결부(144)로 전달된다.Next, when the driving motor 138 is driven, the driving force is transmitted from the driving force transmission member connection 134 of the driving member 130 to the driving force transmission member connection 144 of the driven member 140 through the driving force transmission member 150 do.

다음으로, 구동회전체(132)와 종동회전체(142)가 일방향으로 동시 회전되면서 그 사이에 위치된 주사바늘(14)의 연결구(16)를 주사기 몸체(12)에서 분리시키며, 이 경우 감지부(S)가 이를 감지하여 구동모터(138)에 구동신호를 정지하게 된다. 이때, 본체(110)의 바닥면에 홀이 형성되는 경우 홀을 통해 분리된 주사바늘(14)이 낙하하게 된다.Next, while the driving rotating body 132 and the driven rotating body 142 are simultaneously rotated in one direction, the connector 16 of the injection needle 14 positioned therebetween is separated from the syringe body 12, in this case, the sensing unit (S) detects this and stops the driving signal to the driving motor 138. In this case, when a hole is formed in the bottom surface of the main body 110, the injection needle 14 separated through the hole falls.

한편, 주사바늘(14)의 연결구(16)가 기준보다 큰 것이 유입되면 종동회전체(142)가 구동회전체(132)로부터 후진하게 되며, 제2 스프링(178)은 압축 상태를 유지하게 된다. 이렇게, 종동회전체(142)가 후진하게 되면 구동력 전달부재(150)가 긴장되면서 양측 제1 텐션부재(160)의 제1 지지부(165)를 대칭 방향으로 이동시킨다. 그 후, 주사바늘(14)의 연결구(16)가 기준 크기로 유입되면 종동회전체(142)가 구동회전체(132) 방향으로 전진하게 되며, 제2 스프링(178)은 신장 상태를 유지하게 된다. 이렇게, 종동회전체(142)가 전진하게 되면 구동력 전달부재(150)가 완화되면서 양측 제1 텐션부재(160)의 제1 지지부(165)를 대칭 반대 방향으로 이동시킨다. On the other hand, when the connector 16 of the injection needle 14 is larger than the reference, the driven rotation body 142 moves backward from the driving rotation body 132, and the second spring 178 maintains a compressed state. In this way, when the driven rotation body 142 moves backward, the driving force transmission member 150 is tensioned and the first support portions 165 of the first tension members 160 on both sides are moved in a symmetrical direction. After that, when the connector 16 of the injection needle 14 flows into the reference size, the driven rotation body 142 advances in the direction of the driving rotation body 132, and the second spring 178 maintains an elongated state. . In this way, when the driven rotation body 142 moves forward, the driving force transmission member 150 is relaxed, and the first support portions 165 of the first tension members 160 on both sides are moved in the opposite direction symmetrically.
