<p>The present invention relates to a flow meter using a drop sensor, an infusion pump using the same, and a tester. The flow meter comprises a fluid chamber in which an infusion is stored; a drop sensor measuring a cycle of infusion drops passing from the fluid chamber to a drip chamber, and calculates a dosage by calibrating areas of drops changed depending on the cycle of the infusion drops. According to the present invention, the flow meter measuring the speed of infusion dropping from the drip chamber and flowing in an injection tube can be economically embodied just by measuring the dropping cycle of the infusion drops, and additionally, the infusion pump and the tester for the infusion pump more accurate than the existing one can be embodied by using the flow meter.</p> |
