Abstract
A device is disclosed for draining flexible fluid containers, in particular blood bags which form part of an extracorporeal system in a single needle-type arrangement, having a movable plate (4b) and a fixed plate (4a) in which both plates are configured to confront a flexible fluid container. A force member (14), and a force transfer means (8, 18), are arranged in such a way that the force acting upon the movable plate (4b) increases as the container is drained.
