摘要：
An acne extruder using negative pressure has a housing and a perforated extrusion member moving in the longitudinal direction in the housing. The perforated extrusion member has a member for supporting a needle and generating negative pressure, a needle, a push bar, and a spring. The member for supporting a needle and generating negative pressure slides in close contact with the inner wall of the housing. The needle is coupled to the member for supporting a needle and generating negative pressure and selectively protrudes through one opening of the housing. The push bar engages with a push bar engagement portion to move the member for supporting a needle and generating negative pressure in the direction of the one opening of the housing. The spring is engaged with the housing, the member for supporting a needle and generating negative pressure to elastically press the member for supporting a needle and generating negative pressure in the direction of the other opening. According to the acne extruder using negative pressure of the present invention, micro-perforations are formed in the acne using the needles, thereby minimizing scars in a treatment area and minimizing pain incurred since the scar is not left on the treated area and the skin is not scratched.COPYRIGHT KIPO 2017음압을 이용한 여드름 압출기는 하우징과 하우징 내에서 길이 방향으로 이동하는 천공 압출 부재를 갖는다. 천공 압출 부재는 바늘지지 및 음압발생 부재, 바늘, 누름바, 스프링을 갖는다. 바늘지지 및 음압발생 부재는 하우징의 내벽에 밀착되어 슬라이딩한다. 바늘은 바늘지지 및 음압발생 부재에 결합하여 하우징의 일측 개방구를 통해 선택적으로 돌출한다. 누름바는 누름바 결합부에 결합하여 바늘지지 및 음압발생 부재를 하우징 내에서 일측 개방구의 방향으로 이동시킨다. 스프링은 하우징과 바늘지지 및 음압발생 부재에 결합하여 바늘지지 및 음압발생 부재를 타측 개방구의 방향으로 탄성 가압한다.
