Abstract: A peristaltic pump (200) is proposed which comprises a first housing component (210) and a second loading component (230), said second loading component being at least partially contained within said first housing component and being axially movable with respect to said first housing component inside thereto. The second loading component further comprises at least a couple of rollers (235) which engage and squeeze a delivery tube (146) for delivering a fluid passing there through when, in operation, the second loading component is fully snapped into said first housing component. Moreover the second loading component comprises a guiding path (240) for guiding the delivery tube around said at least a couple of rollers towards an exit port (244) which is provided at a distal end surface of the second loading component. The present invention also relates to a patient set and to an injection system comprising said peristaltic pump, as well as to a method of operating said injection system.
