Abstract
A pump device () for administering a medical fluid to a patient comprises a holding device () for receiving a syringe barrel () of a syringe (), the holding device () comprising a stationary section () and a holding member () movable with respect to the stationary section () between an opened position and a closed position, wherein the holding member () is configured to secure, in the closed position, the syringe barrel () of a syringe () received on the holding device () with respect to the stationary section (). A shaft () is coupled to the holding member (), the shaft () being constituted to rotate during a movement of the holding member (). Herein, a damping device () comprises a movable part () connected to the shaft () and rotatable together with the shaft () and a stationary part () fixed with respect to the stationary section () of the holding device (), a rotational movement of the movable part () with respect to the stationary part () providing for a damping of the movement of the holding member (). In this way a pump device for administering a medical fluid to a patient is provided which may provide for a secure fastening of a syringe barrel and at the same time helps to avoid a damaging of in particular smaller syringes by clamping forces of the holding member.
