Abstract
An infusion device (1) for administering a medical fluid to a patient (P) comprises a pumping mechanism (4) configured to act onto a fluid conduit (20), the pumping mechanism (4) comprising a pumping section (42) movable with respect to said fluid conduit (20) for causing a fluid flow (F) through said fluid conduit (20). The pumping mechanism (4) comprises a multiplicity of rotatable gear elements (45A-45E) coupled to the pumping section (42) at a multiplicity of different locations (43A-43E), wherein the gear elements (45A, 45E) are operatively coupled to each other for a coordinated rotation of the gear elements (45A-45E) for moving the pumping section (42). In this way an infusion device is provided which may allow for a small-sized pumping mechanism, yet providing for a reliable and efficient infusion operation.
