About.

또한, 본 발명은 주사바늘을 고정하기 위해 충진되는 접착제(에폭시)가 고정홈 내에서 자중에 의해 가라 앉으면서 양생(건조)됨에 따라 고정홈 위로 솟아나지 않도록 하는 바, 이는 일자 형태의 평면 확보가 가능하여 약물 주입에 따른 통증 유발 요소(솟아오른 뽀족한 돌출부가 약물 주입시 피부에 닿으면 찔림과 같은 통증을 유발하게 됨)가 원천적으로 제거될 수 있도록 하는 것을 특징으로 한다.In addition, the present invention prevents from rising above the fixing groove as the adhesive (epoxy) filled to fix the injection needle is cured (dried) while sinking by its own weight in the fixing groove. It is characterized in that it is possible to fundamentally remove the pain-causing factor (protruding pointed protrusions that contact the skin during drug injection, causing pain such as stabbing) due to drug injection.

또한, 본 발명은 소캡의 삽입공 바깥측 테두리에 플렌지 날개가 돌출되도록 하되, 상기 플렌지 날개는 허브의 개구부와 대응되면서 압착 끼움 고정도되도록 하는 바, 이는 허브 내 주사바늘의 외부 노출을 차단하도록 형성되어 주사바늘에 의한 찔림 위험과 2차 감염과 같은 안전사고의 위험을 방지하도록 하는 것을 특징으로 한다. In addition, the present invention allows the flange blade to protrude from the outer edge of the insertion hole of the small cap, and the flange blade corresponds to the opening of the hub so as to have a high degree of compression fitting, which is formed to block the external exposure of the injection needle in the hub. It is characterized in that it prevents the risk of puncture by the needle and the risk of safety accidents such as secondary infection.

또한, 본 발명은 허브, 소캡, 대캡의 원주방향 외주면에 각각 돌기띠(돌기선 또는 돌기체)를 형성하여 그립감을 크게 높임은 물론 돌기띠(돌기선 또는 돌기체)는 조립이나 후처리에 대한 그립(잡기)시 넓고 낮은 돌출면을 갖도록 형성되어 당뇨환자의 그립 통증을 최소화하도록 하는 것을 특징으로 한다.In addition, the present invention greatly enhances the grip by forming a protrusion strip (protrusion line or protrusion body) on the outer circumferential surface of the hub, the small cap, and the large cap, respectively, as well as the protrusion strip (protrusion line or protrusion body) for assembly or post-processing. It is characterized in that it is formed to have a wide and low protruding surface when gripping (grabbing) to minimize grip pain in diabetic patients.

일반적으로 펜 니들은 니들(N)이 장착된 허브를 통칭하며 여기에 소캡, 중캡, 멸균용 마감재를 포함하여 펜 니들 세트로 구성된다.In general, a pen needle refers to a hub equipped with a needle (N), and is composed of a pen needle set including a small cap, a middle cap, and a sterilization finish.

도 7의 (b)는 종래의 펜 니들 세트 모양을 표현한 단면도로서, 허브의 중앙에 니들(N)이 장착되어 있고, 그 위에는 소캡이 씌워져 있다.7B is a cross-sectional view showing the shape of a conventional pen needle set, in which a needle N is mounted in the center of a hub, and a small cap is covered thereon.

그리고, 소캡의 위에는 대캡이 덮어씌워져 있으며, 허브의 저면에는 멸균용 마감재가 부착되어 밀봉돼 있다.And, the large cap is covered on the top of the small cap, and the sterilization finish is attached to the bottom of the hub and sealed.

한편, 펜 니들 사용 시에는 허브 하단 면에 부착된 멸균용 마감재를 제거하고, 대캡 및 소캡이 씌워져 있는 펜 니들을 펜 타입 주사기에 나사결합 방식으로 체결 결합한다.On the other hand, when using a pen needle, remove the sterilization finish attached to the lower side of the hub, and fasten and connect the pen needle with the large cap and the small cap on the pen type syringe by screwing.

이후, 대캡 및 소캡을 순차적으로 제거하고, 자가주사를 이행하게 되며, 사용 후에는 니들(N) 위에 소캡 또는 대캡을 다시 덮어씌운 후 펜 타입 주사기로부터 펜 니들을 최초 대비 역회전방향으로 나사방향을 풀어 분리한 뒤 폐기 처리하도록 형성된다.Thereafter, the large cap and small cap are sequentially removed and self-injection is performed.After use, the small cap or large cap is re-covered on the needle (N), and the screw direction is reversed from the pen-type syringe compared to the first time. It is formed to disassemble after being released and separated.

한편, 사용자가 펜 니들을 사용한 이후 펜 타입 주사기로부터 펜 니들을 분리하고자 할 경우에는 사용자가 소캡 또는 대캡을 1회 사용된 니들(N)에 덮어씌워야 하는 과정이 필요하게 된다.On the other hand, when the user wants to separate the pen needle from the pen-type syringe after using the pen needle, a process in which the user must cover the small cap or the large cap on the once used needle N is required.

이때, 사용자는 소캡을 니들(N)에 씌우지 않고 바로 분리를 시도하는 과정(또는 허브를 나사 풀림 방식으로 회전시키는 과정)에서 외부로 노출되어 있는 니들(N)에 의해 찔리거나 긁히는 등의 안전사고가 발생되어 출혈과 통증이 유발되는 경우가 빈번하게 일어나고 있는 실정이다.At this time, the user does not put the small cap on the needle (N), but in the process of attempting to separate it immediately (or the process of rotating the hub by the screw loosening method), a safety accident such as being poked or scratched by the needle (N) exposed to the outside. The occurrence of bleeding and pain is frequently occurring.

또한, 당뇨 환자들은 중증으로 갈수록 손 끝이 벗겨지고 거칠고 약해지는데, 종전의 펜 니들은 대단히 소형의 크기로서 잡기에 따른 손가락의 통증이 크게 유발되고 감각이 떨어져 놓치는 등의 문제가 발생된다.In addition, as the diabetic patients become more severe, the fingertips are peeled off and rough and weak. Conventional pen needles are very small and cause great pain in the fingers due to the gripping and loss of sensation occurs.

즉, 자가 치료시 1회용으로 제공되는 주사 키트를 놓치거나 취급하기 어려운 문제가 있으며 자칫 바늘에 찔려 2차 감염사고나 부차적인 통증에 노출되는 문제가 발생된다.That is, during self-treatment, there is a problem of missing or difficult to handle an injection kit provided for a single use, and there is a problem of being exposed to secondary infection accidents or secondary pain by being stabbed by a needle.

다음은 첨부된 도면을 참조하며 본 발명을 보다 상세히 설명하겠다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

도 1 내지 도 6에 도시된 바와 같이, 본 발명은 허브(100)와 소캡(200) 및 대캡(300)으로 크게 구성된다.As shown in Figures 1 to 6, the present invention is largely composed of a hub 100, a small cap 200 and a large cap 300.

이에, 상기 허브(100)는 컵 형태의 몸통(110) 일단에 개구부(120)가 형성되도록 하되, 상기 개구부(120)측 내주면에는 인슐린 펜의 결합탭(10)에 대응되면서 나사체결되도록 나사부(121)가 형성된다.Accordingly, the hub 100 has an opening 120 formed at one end of the cup-shaped body 110, but the inner circumferential surface of the opening 120 side corresponds to the coupling tab 10 of the insulin pen and is screwed so as to be screwed ( 121) is formed.

이때, 상기 개구부(120)와 대향되는 반대측 타단에는 지지판(130)을 갖는 돌출블럭(140)이 형성된다.In this case, a protruding block 140 having a support plate 130 is formed at the other end opposite to the opening 120.

이에, 상기 지지판(130)의 중앙부에는 수직 축선과 대응되는 주사바늘(150)이 고정홈(131)을 관통하면서 접착제(에폭시)로 하여금 접합 고정되도록 형성된다.Accordingly, the injection needle 150 corresponding to the vertical axis is formed in the central portion of the support plate 130 to be bonded and fixed by an adhesive (epoxy) while penetrating the fixing groove 131.

이에, 상기 돌출블럭(140)은 직경이 몸통(110) 직경 대비 2/3~4/5 크기로 형성되어 통증 방지용 대구경 형태인 것이 바람직하다.Accordingly, it is preferable that the protruding block 140 has a diameter of 2/3 to 4/5 compared to the diameter of the trunk 110 and has a large diameter shape for preventing pain.

또한, 상기 몸통(110)은 원주 방향 외주면에 그립감을 높이기 위한 돌기띠(111)가 다수 형성되도록 하는 것이 바람직하다.In addition, it is preferable that the body 110 has a plurality of protrusion bands 111 for enhancing a sense of grip on the outer circumferential surface in the circumferential direction.

이러한 돌기띠는 바깥으로 돌출된 높이가 낮고 옆으로 연장된 면적이 넓어 잡기시 손가락에 통증이 유발되지 않도록 형성된다.The protruding band has a low protruding height and a wide area extending to the side so that pain is not caused to the finger when gripping.

이때, 상기 주사바늘을 고정하는 접착제(에폭시)는 고정홈(반달형 또는 물방울 모양)에서 위로 넘치지 않도록 충진한 뒤 일정 시간 지나면 충진된 에폭시가 일부 가라 앉아 지지판의 상면 위로 접착제가 돌출되지 않도록 형성된다.At this time, the adhesive (epoxy) that fixes the injection needle is filled so that it does not overflow from the fixing groove (half moon or water droplet shape), and after a certain period of time, the filled epoxy partially sinks and the adhesive does not protrude above the upper surface of the support plate.

이는 평면상 솟아오르는 면이 없도록 하여 통증을 방지하도록 하기 위함이다.This is to prevent pain by making sure that there is no surface rising on the plane.

한편, 상기 소캡(200)은 원통체(210)의 일측에 삽입공(220)이 형성되어 돌출블럭(140)의 외주면과 대응되면서 끼워지도록 하되, 내부에는 주사바늘(150)이 수용될 수 있도록 공간부(230)가 형성된다.On the other hand, the small cap 200 has an insertion hole 220 formed on one side of the cylindrical body 210 so that it is fitted while corresponding to the outer circumferential surface of the protruding block 140, so that the injection needle 150 can be accommodated therein. The space part 230 is formed.

이때, 상기 삽입공(220)의 바깥측 테두리에는 플렌지 날개(240)가 형성되어 주사사용이 완료되면 허브의 개구부(120)를 향해 플렌지 날개(240)가 억지 끼움되면서 압착 고정되도록 형성된다.At this time, the flange blades 240 are formed on the outer rim of the insertion hole 220 so that when the injection use is completed, the flange blades 240 are forcibly fitted toward the opening 120 of the hub to be compressed and fixed.

이에, 상기 공간부가 주사바늘(허브의 내부공간에 관통된 바늘의 일단)을 향하면서 끼워지도록 하는 바, 이는 주사바늘에 손가락이 찔리지 않도록 외부 노출을 차단게 된다.Accordingly, the space portion is fitted while facing the injection needle (one end of the needle penetrating the inner space of the hub), which blocks external exposure so that the finger is not pierced by the injection needle.

또한, 그립갑을 높이기 위해 원통체의 직경은 허브의 돌출블럭 보다 소폭 더 넓게 직경이 형성된다.(손가락으로 집었을 때 통증을 방지함)In addition, the diameter of the cylindrical body is slightly wider than the protruding block of the hub to increase the grip (prevents pain when pinched with a finger).

이때, 원통체의 원주방향 외주면에는 그립감을 더 높이기 위해 돌기선(250)이 형성된다. 이러한 돌기선은 바깥으로 돌출된 높이가 낮고 옆으로 연장된 면적이 넓어 잡기시 손가락에 통증이 유발되지 않도록 형성된다.At this time, a protrusion line 250 is formed on the outer peripheral surface of the cylindrical body in the circumferential direction to further increase a sense of grip. The protruding line has a low protruding height and a wide area extending to the side so that pain is not caused to the finger when gripping.

또한, 플렌지 날개는 신축성이 있는 구조로 억지 끼움 형태로 개구부에 압착고정되도록 형성된다.In addition, the flange wing is formed to be compressed and fixed to the opening in the form of force-fitting in an elastic structure.

이에, 상기 개구부에는 플렌지 날개가 이탈, 분리되는 것을 방지하도록 걸림턱 또는 쐐기형 단속구가 더 형성되는 것이 바람직하다.Accordingly, it is preferable that a locking jaw or a wedge-shaped interrupter is further formed in the opening to prevent separation or separation of the flange blade.

또한, 상기 플렌지 날개는 단면 두께 중 들어가는 측에 경사면이 형성되고, 바깥측에 해당하는 측에는 꺽임부가 형성되어 한번 장착되면 파손 외에 분리가 거의 어렵도록 형성되어 재활용이 방지되도록 형성되는 것이 바람직하다.In addition, it is preferable that the flange blade is formed such that an inclined surface is formed on the entering side of the cross-sectional thickness, and a bent part is formed on the side corresponding to the outer side, and is formed so that it is almost difficult to separate other than damage once mounted, thereby preventing recycling.

한편, 상기 대캡(300)은 콘 형태의 몸체 일측에 내입홈(310)이 형성되어 소캡(200)이 결합된 허브(100)가 내장되도록 형성된다.On the other hand, the large cap 300 is formed such that the inner inlet groove 310 is formed on one side of the cone-shaped body so that the hub 100 to which the small cap 200 is coupled is embedded.

이에, 상기 대캡에는 그립갑을 높이기 위해 몸체의 원주방향 외주면에 돌기체(330)가 형성되는 것이 바람직하다.Accordingly, it is preferable that the large cap has a protrusion body 330 formed on the outer circumferential surface of the body in the circumferential direction to increase the grip cap.

이러한 돌기체는 바깥으로 돌출된 높이가 낮고 옆으로 연장된 면적이 넓어 잡기시 손가락에 통증이 유발되지 않도록 형성된다.These protrusions have a low protruding height and a wide area extending laterally so that pain is not caused to the fingers when gripping.

한편, 상기 내입홈(310)을 통해 수납된 소캡(200)과 허브(100) 중 허브의 개구부에는 멸균용 페이퍼(320)가 최초 부착되었다가 사용시 떼어 분리할 수 있도록 형성된다.On the other hand, the sterilization paper 320 is first attached to the opening of the hub among the small cap 200 and the hub 100 accommodated through the inner inlet groove 310, and is formed to be detached when used.
