Abstract

A slit disk having a hole at a specified portion of its flat surface and a plurality of slits at regular intervals at a peripheral portion thereof is mounted to a shaft of an infusion pump. A controller clears a live band determination counter based on a light detection signal from a sensor when the hole is detected, and increments the count value of a live band determination counter when an side edge of one of the plurality of slit is detected. When the count value of the live band determination counter falls within '10' to '24' or '0' to '2', it is determined that the infusion pump is in a live band, and the count value of the live band counter is incremented. Thus an operation amount of the infusion pump in the live band is detected to measure a fluid delivery rate taking a dead band into account.
