Abstract
A drip infusion rate control apparatus controlling the flow rate of a medical solution to be infused into a human or animal body by means of a drip infusion system. The apparatus includes a weight measuring means for measuring the weight of a medicine bottle containing a medical solution being infused into a human or animal body through an infusion tube led out from the medicine bottle, an existing flow rate data computing means for computing, by using at least time-dependently varying weight data outputted from the weight measuring means, an existing flow rate reflecting value which reflects an existing flow rate of the medical solution flowing in the infusion tube, an aiming value outputting means for outputting a set of reference flow rate data defining an aiming flow rate expected to the medical solution, a basic data inputting means for inputting a set of basic data necessary for the aiming value outputting means to output the set of reference flow rate data, a comparator for comparing the existing flow rate reflecting value with at least one of the reference flow rate data contained in the set of reference flow data, and outputting a flow rate control signal, and a flow rate …
