Description

안전 펜 니들{BEING SAFE DISPOSABLE PEN NEEDLE}Safety pen needle {BEING SAFE DISPOSABLE PEN NEEDLE}

본 발명은 펜 니들에 관한 것으로서, 특히 사용이 종료된 니들의 주변을 안전하게 커버링하여 락킹하는 안전 펜 니들에 관한 것이다.The present invention relates to a pen needle, and more particularly, to a safety pen needle that securely covers and locks the periphery of the used needle.

펜 타입 주사기로 제공되는 펜 니들은 인슐린 투여 등 정기적인 정량의 약제의 투여가 필요한 경우에 간편하게 휴대하여 사용된다. 펜 니들은 당뇨병 환자와 같이, 스스로 자주 주사를 필요로 하는 사용자의 편리성을 위해 주로 만들어졌다. 펜 니들은 수회에서 수십 회 주사가 가능한 약재가 펜 몸체에 수용되어 있으며, 펜 몸체에 1회성의 니들 조립체를 체결하여 누름 동작만으로 작동되어 일정량의 약제가 인체로 주사될 수 있도록 보급된다.The pen needle provided as a pen-type syringe is conveniently used when it is necessary to administer a fixed amount of a medicine such as insulin. The pen needle is mainly made for the convenience of users who frequently need injections themselves, such as diabetics. Pen needle is a medicine that can be injected several times to several dozen times is accommodated in the pen body, and is fastened by fastening a one-time needle assembly to the pen body to operate only by a pressing operation so that a certain amount of the medicine can be injected into the human body.

펜 니들의 주된 기술이슈는 사용된 니들의 재사용을 근본적으로 차단하고, 폐기처리 시 첨예한 니들에 의한 찔림 사고로 2차 감염이 발생되는 것을 원천적으로 예방하는 것이다. 종래의 경우, 펜 니들의 제조회사들은 다양한 메커니즘으로 한번 토출된 니들을 불능화 시키거나 락킹하여 펜 니들의 1회성을 구현한다. The main technical issue of the pen needle is to fundamentally prevent reuse of the used needle and to prevent the occurrence of secondary infection due to a stabbing accident by a sharp needle during disposal. In the conventional case, the manufacturers of the pen needle disable or lock the needle once ejected by various mechanisms to realize the one-time use of the pen needle.

선행기술로, 등록실용신안 제20-0486781호는 작동된 니들이 삽입 압력으로 구부려지도록 구성되어 사용불능화 시키고 안전하게 분리 배출할 수 있도록 제공한다. 1회성의 폐기처리를 위한 펜 니들의 구성에서, 현장에서 고려되는 주된 이슈는 제조단가의 최소화이다. 1회성 소모품의 특성상 고도로 복잡한 구조가 요구되거나, 지나치게 많은 사출품이 구성요소로 요구된다면, 펜 니들 고유의 구성품보다 펜 니들을 안전하게 폐기하기 위해 부가되는 구성품의 제조단가가 소비자 가격을 지나치게 상승시키는 문제점을 야기한다.As a prior art, the registered utility model No. 20-0486781 is configured to bend the operated needle with an insertion pressure, thereby disabling it and providing safe separation and discharge. In the configuration of the pen needle for one-time disposal, the main issue considered in the field is minimization of manufacturing cost. If a highly complex structure is required due to the nature of a one-time consumable, or if too many injection products are required as components, the manufacturing cost of components added to safely dispose of the pen needle rather than the components unique to the pen needle increases the consumer price excessively.
