摘要： A peristaltic dosing device (1) for providing dosages of a fluid at a volume of less than one milliliter comprises: a flexible tube (13), a counter pressure element (12), a plurality of actors (11) and a drive (17). The flexible tube (13) is essentially straightly arranged along the counter pressure element (12) thereby forming a longitudinal axis. The actors (11) arranged parallel to each other along the longitudinal axis. They are moveable by the drive (17) in relation to the flexible tube (13). The flexible tube (13) is compressible between the actors (11) and the counter pressure element (12) by moving the actors (11). Each of the actors (11) is independently and linearly moveable by the drive (17) along an actuation axis essentially perpendicular to the longitudinal axis of the flexible tube (13) from a home position in which the flexible tube (13) is least compressed to an end position in which the flexible tube (13) is compressed and sealed between the respective actor and the counter pressure element (12). The peristaltic dosing device according to the invention allows for exactly and repeatably providing dosages at comparably small volumes in a sterile environment.
