ABSTRACT:
A portable infusion pump for delivering medicine to a living body has a roller pump for infusing solutions by use of a motor, a driving circuit for driving the motor in response to a control signal, and a flow rate control for generating the control signal. The flow rate control includes a manual operating unit for manually setting a value of a speed of the motor, a speed setting unit for generating a digital signal associated with the value set by the manual operating unit, and a control signal output unit for generating the control signal associated with the digital signal delivered from the speed setting unit. Accordingly, the flow rate thus set clearly corresponds to an actual flow rate, thus facilitating the control of the liquid flow rate.
