Abstract
The present invention relates to an apparatus and a system for controlling an amount of medicine or fluid injection through falling due to potential energy of the fluid. For example, the present invention can automatically adjust an injection rate of a medicine injected into a patient by controlling an opening/closing degree of a medicine hose by using a driving element driven by electric power according to a comparison of the number of drops with a predetermined value. An apparatus for realizing the method includes an accommodating case for accommodating a connecting portion for connecting a fluid, a detection unit for detecting the number of drops, a control unit for comparing the information detected by the detection unit, and a driving element for opening and closing a passage of the medicine hose based on the contents analyzed by a control unit.
