A medical device () for administering a medical fluid to a patient () comprises a housing () comprising a housing portion (), a control device () for controlling operation of the medical device (), a control element () placed on said housing portion () and being actuatable for entering a control command to be input to the control device (), wherein the control element (), for actuation, is at least one of rotatable about an axis of rotation (R) and linearly movable along the axis of rotation (R) with respect to said housing portion (), and an actuation element () operatively connected to the control element () for actuating the control element (). Herein, the actuation element () comprises a first knob element () operatively connected to the control element () and a second knob element () supported on said housing portion ().

Medical device comprising an actuation element

All infusion device () for administering a medical fluid to a patient comprises a receptacle () for receiving a syringe (), a pusher device () movable in a pushing direction (P) for acting onto a piston () of the syringe () received in the receptacle (), a driving rod (), an electric drive device () for driving the driving rod (), and a clutching device () comprising a frame member () and at least one clutch element (A,B) movably arranged on the frame member (). The at least one clutch element (A,B) is constituted to operatively connect, in a clutched state, the driving rod () to the pusher device () for driving the pusher device () by the electric drive device (). The clutching device () is actuatable to assume an unclutched state in which the operative connection between the driving rod () and the pusher device () is released. Herein the clutching device () comprises a lock element () for locking the at least one clutch element (A,B) in the clutched state. In this way, an infusion device is provided which in an easy and reliable manner allows for maintaining the clutching device in the clutched state during operation of the infusion device.

Infusion device having a clutching device

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.

An infusion device () for administering a medical fluid to a patient, comprises a housing () and a receptacle () arranged on the housing () for receiving a syringe (), the syringe () having a barrel () for containing a medical fluid and a plunger () movable relative to the barrel () for delivering the medical fluid out of the barrel (). A pusher device () is movable relative to the housing () for acting onto the plunger () for moving the plunger () relative to the barrel (), and a drive mechanism () drives the pusher device (). A coupling mechanism () is operative to couple the plunger () to the pusher device () or to couple the pusher device () to the drive mechanism (), and an actuation mechanism arranged on the pusher device () comprises an actuation element () for actuating the coupling mechanism () between a coupling state and an uncoupling state. Herein, the actuation mechanism comprises a first threaded element () rotatable about a rotational axis () and a second threaded element () movable along the first threaded element (), the second threaded element () being in threaded engagement with the first threaded element () such that the first threaded element () is rotated when the second threaded element () is moved along the first threaded element (), wherein the actuation element () is actuatable to move the second threaded element () along the first threaded element (), the first threaded element () being operatively connected to the coupling mechanism (). In this way an infusion device is provided which in an easy and comfortable manner allows a user to actuate a coupling mechanism, in particular for installing a syringe on a receptacle of the infusion device.
