摘要

The device (1a) has a cannula (2), a suction device (3) and a collection container (4) for removed flowable medium, which are connected with one another over a connection unit (5) i.e. three way plug. A non-return valve (6a) is arranged between the cannula and the connection unit, and is opened in the direction of the connection unit. Another non-return valve (6b) opened in the direction of the container is arranged between the connection unit and the container, where the valves are arranged at a distance to each other over a flexible hose element (7).
