Abstract
A monitoring system for a medical pump having a reversible operating body for compressing/expanding a space for accommodating a fluid, suction/ejection ports communicating via a no-return valve with this space and units for driving the reversible operating means. The system comprises modules for informing abnormalities in the case of a stoppage for predetermined period at a top or bottom dead center of the reversible operating body, or when this body does not traverse predetermined positions, or when the top or bottom dead center exceeds limit positions, or when a centroidal position of the reversible operating body deviates from a set range, and a module for measuring a flow rate of the blood ejected from the artificial heart by calculating an internal volume of the reversible operating body from the images photographed.
