PURPOSE: A flow controller for an infusion device is provided to minimize a medicine retention space at the top of a capillary tube, thereby discharging air through the capillary tube smoothly when injecting medicine.CONSTITUTION: A flow controller for an infusion device comprises a medicine inlet tube, a medicine outlet tube, and an elastic ring. The medicine inlet tube is connected to a medicine storage part through a connection tube. The medicine outlet tube is connected to the medicine inlet tube and other devices or an injection needle to deliver medicine. The elastic ring is located in the coupling section between the medicine inlet tube and the medicine outlet tube and prevents medicine injected into a capillary tube from leaking outside. The capillary tube controls the infusion amount of medicine.COPYRIGHT KIPO 2013본 발명은 약물의 주입량을 조절절하는 조절기에 관한 것으로 더욱 상세하게는 약물 저장부의 압력으로 약물을 주입하는 기기의 모세관의 구경과 길이를 변경하여 약물의 주입량을 조절하는 조절기로 모세관에 설치한 탄성링을 이용하여 모세관 막힘을 방지하는 것을 특징으로 하는 것이다.
