The length of the product is also very short, usually less than 12 mm, and has characteristics of being produced and used.
한편, 사용자가 주사약제를 자가투여하기 위해서는 먼저 펜 타입 주사기의 앰플카트리지(1) 상단에 구비되어 있는 니들 체결부(2)에, 멸균 마감용 봉인지(Seal)(15)를 제거한 다음 니들 대캡(13) 속에 수용되어 있는 펜 니들(11)의 체결부(11b)를 나선체결방식으로 수회 가량 회전시켜 결합하여야 한다. On the other hand, in order for the user to self-administer the injection drug, first remove the seal 15 for the sterilization finish on the needle fastening part 2 provided at the top of the ampoule cartridge 1 of the pen type syringe, and then remove the needle cap. (13) The fastening part 11b of the pen needle 11 accommodated in the inside should be rotated several times in a spiral fastening manner to be coupled.
그 후에, 주사약제 사용량을 세팅하고, 니들 소캡(12)를 제거하여 니들(11c)이 노출되도록 한 후, 상기 니들(11c)을 인체나 동물의 표피에 찌른 다음 정해진 주사 약제만큼 주사한다. Thereafter, the injection drug amount is set, the needle small cap 12 is removed to expose the needle 11c, and then the needle 11c is poked in the epidermis of the human body or animal and then injected as much as the prescribed injection drug.
주사가 완료된 후에는, 사용된 펜 니들(11)을 앰플 카트리지(1)으로부터 분리 시에는 상기 결합 시와 반대로 사용된 펜 니들(11)에 다시 니들 대캡(13)을 씌우거나 분리배출기능이 구비된 별도의 덮개 내부 또는 별도의 분리 기구에 삽입하여 좌회전 또는 우회전 방향으로 2~4회 역 회전시켜 나사 풀림 방식으로 각각 분리하는 방식이었다. 이와 같은 나사식 체결 방식의 기존의 펜니들과 관련된 선행 발명으로는, "펜 타입 주사기 허브(대한민국 공개실용신안 제20-2016-0003736호)"를 포함하여 다수의 선행 발명들이 존재한다.After the injection is completed, when the used pen needle 11 is detached from the ampoule cartridge 1, the needle pen cap 11 is put on the used pen needle 11 again, as opposed to the above-mentioned combination, or a separate discharge function is provided. It was a method of separating each by a screw loosening method by reversing 2 to 4 times in the left or right rotation direction by inserting into a separate cover inside or a separate separation mechanism. As a prior art related to the existing pen needle of the screw-type fastening method, there exist a number of prior inventions, including "Pen type syringe hub (Republic of Korea Utility Model No. 20-2016-0003736)".
그러나 이러한 종래의 펜 니들의 경우, 펜 타입 주사기에 펜 니들을 체결하거나 탈거하기 위해서는 나사 형식으로 구성된 니들 체결부(2)에 역시 나사 형식으로 구성된 체결부(11b)를 나사 체결 방식으로 수회 이상 회전 시켜야 하기에, 시력 및 거동이 불편한 노약자 등의 경우에는 그 체결 및 탈거 작동이 불편하고 쉽지 않다는 문제점이 있었다. However, in the case of such a conventional pen needle, in order to fasten or remove the pen needle to the pen-type syringe, the screw fastening part 11b is also rotated several times by a screw fastening method to the needle fastening part 2 composed of a screw type. Since it should be done, in the case of the elderly, etc., who have inconvenient eyesight and behavior, there is a problem that the fastening and detaching operation is inconvenient and not easy.
또한, 기존의 펜 니들은 도 1에 나타낸 것과 같이 니들(11c)을 니들 허브(11a)에 고정하는 니들 장착부(11d)가 니들 허브(11a)의 상측면으로부터 돌출되도록 형성되어 있었다. 이러한 기존의 펜 니들은 사용자의 신체에 니들을 찔러 주사하는 경우, 도 2에서 (A)에 나타낸 것과 같이 주사 부위의 피부의 일부분을 집중적으로 압박하여 눌러 들어가게 하는 경우가 많이 발생한다. 이 경우, 주사 부위에 집중되는 압박에 의하여 사용자의 주사 부위의 조직이 부분적으로 압박되어 원활한 주사액의 주입을 방해하는 문제가 발생할 수 있다. 또한, 펜 니들은 오직 사용자의 신체에 삽입된 니들(11c) 또는 국소적으로만 사용자의 피부에 접촉 지지되는 니들 장착부(11d)에 의해서만 지지되므로, 주입 과정에서 약간이라도 움직임이 발생하는 경우 이러한 움직임에 의한 힘이 니들(11c)이 니들 장착부(11d)에 설치된 부분에 집중되어 도 2에서 (B)에 나타낸 것과 같이 니들(11c)이 쉽게 휘어지거나 변형되어 주입이 어렵거나 불가능해지는 경우가 자주 발생한다는 문제점이 있었다. In addition, the conventional pen needle was formed so that the needle mounting portion 11d for fixing the needle 11c to the needle hub 11a as shown in FIG. 1 protrudes from the upper surface of the needle hub 11a. When such a conventional pen needle pierces a needle into a user's body, a lot of cases in which a part of the skin of the injection site is intensively pressed and pressed, as shown in FIG. In this case, there may be a problem that the tissue of the injection site of the user is partially compressed by compression concentrated on the injection site, thereby preventing smooth injection of the injection solution. In addition, since the pen needle is supported only by the needle 11c inserted into the user's body or the needle mounting portion 11d supported in contact with the user's skin only locally, such movement occurs even if slight movement occurs during the injection process As the force caused by the needle 11c is concentrated on the portion installed in the needle mounting portion 11d, as shown in FIG. 2(B), the needle 11c is easily bent or deformed and injection is often difficult or impossible. There was a problem.
