Abstract

A liquid separator for use as a blood component separator separates a blood component such as blood plasma from centrifugally separated component layers in a flexible blood bag. The blood bag has a liquid discharge tube on its upper end. The liquid separator includes a container holder for holding the blood bag with the liquid discharge tube directed substantially upwardly, and a container presser for pressing the blood bag progressively from the upper end toward a lower end thereof in coaction with the container holder to force the blood component out of the blood bag through the liquid discharge tube. While the blood bag is pressed, a certain thickness is provided at its upper end to allow the blood component to flow out of the blood back through the blood discharge tube.
