Abstract

A transfusion apparatus including a pump section for sequentially pressing and occluding a transfusion tube by means of a plurality of finger elements of a peristaltic type thereby to feed a liquid, a detecting section having (1) a circuit for detecting a given reference position of the pump section to generate a corresponding detection signal during periodic peristaltic movement of the pump section and (2) a circuit for detecting a working position of the pump section deviated from the reference position through the peristaltic movement thereby to generate a corresponding detection signal, and a drive controlling section for receiving the detected signals from the detecting section to compute and control the peristaltic rate thereby to maintain a constant delivery amount by the pump section.
