Abstract:
1. A portable medical liquid infusion device for quantitatively measuring medical liquid infusion rate, and notifying the medical liquid infusion rate by a droplet drop period, the infusion device comprising: a key input unit ( 120 ) which receives a selection of an infusion rate control mode or an infusion rate measuring mode, receives an input of the quantity of medical liquid infused per unit time, receives a count input from a user each time when a droplet ( 23 ) drops downward in a drip chamber ( 22 ), and receives a selection of a droplet volume according to the use of the medical liquid; a display unit ( 130 ) which outputs the quantity of the medical liquid and a length of infusion time input by the user at the infusion rate control mode so that the user can confirm the quantity of the medical liquid and the length of infusion time, and quantitatively outputs the supply rate of the medical liquid calculated at the infusion rate measuring mode; a speaker ( 140 ) which outputs acoustic waves of a predetermined period at the infusion rate control mode; an oscillating unit ( 150 ) for oscillating electric signals of a predetermined frequency; a power supply unit ( 160 ) for supplying power; and a control unit (
