An insulin pump supplies insulin into a syringe, and operates a piston on the lower side of the syringe to inject the insulin into the skin of a user at a fixed time by a syringe needle through a tube connected to a connecting device coupled to a syringe outlet. The present invention relates to a micro insulin pump with an anti-clogging function, which comprises: a round permanent magnet (210) integrally mounted on the lower side of a piston (200) which generates pressure to inject insulin into a syringe (21)； a ring-shaped electromagnet (220) mounted coaxially with the syringe (21) on the outer circumferential surface of the syringe (21) accommodating the piston (200)； a power supply means (130) mounted in an insulin pump housing (120), and reducing the power of a motor (168) to transmit reduced power to a rotating shaft (131) which is mounted to be parallel to the syringe (21) and acts to reduce the height of the housing (120)； a push ring (230) converting the rotary motion of the rotating shaft (131) into rectilinear motion, and integrally and horizontally mounted on the outer circumferential surface of the electromagnet (200)； a vibrator (280) mounted to be overlapped with the upper side or lower side of the ring-shaped electromagnet (220) to transmit vibration power from the electromagnet (220) to the permanent magnet (210)； and a control part (171) controlling an electromagnet actuating part (260) for the actuation of the electromagnet (220) and an ultrasonic wave generating part (270) for the actuation of the vibrator (280). During the upward movement of the electromagnet (220), the piston (200) formed integrally with the permanent magnet (210) moves and also supplies insulin into the tube to prevent clogging by ultrasonic wave generation.본 발명은 시린지에 인슐린을 공급하고, 시린지 저면에서 피스톤을 구동하여 시린지출구에 결합한 연결구와 연결된 도관을 통해 주사침으로 인슐린을 일정 시간마다 사용자 피부로 주사하는 인슐린펌프에서, 시린지에 인슐린을 주사하도록 압력을 발생하는 피스톤의 저면에 일체로 설치한 원형의 영구자석(210)； 피스톤(200)을 수용하는 시린지(21) 부위의 외주면에 시린지(21)와 동축으로 설치되는 링상의 전자석
