Abstract: The peristaltic rotation pump includes the pump segment extending along the working path, which is transversely grooved at the place of contact with the compressed pump segment, and is adjacent along all its length to an elevated circular supporting occlusal path, for rolling of pressure rollers. The working path includes a lead-in path, occlusal path and releasing path. Mechanical linearity of dosing is ensured by a circular occlusal path and the nearly circular releasing path, adjacent along all its length to the elevated supporting occlusal path for rolling of at least three pressure rollers. The angle length of the releasing path corresponding to the distance from the point of the beginning of releasing the pump segment to the point of complete release of the pump segment by the pressure roller is identical with that of the occlusal path.
