An infusion device () for administering a medical fluid to a patient comprises a housing (), a receptacle () arranged on the housing () for receiving a syringe (), a syringe driver () movable in a driving direction (P) for acting onto a piston () of a syringe () received on the receptacle (), and a drive mechanism () for electromotively driving the syringe driver () along the driving direction (P), the drive mechanism () comprising an electric drive motor () and a rotatable drive element () operatively coupled to the syringe driver () for moving the syringe driver () along the driving direction (P). Herein, the drive mechanism () comprises a clutch device () configured, in a coupled state, to couple the drive device () to the drive element () such that the drive device () is operative to drive the drive element () and, in an uncoupled state, to uncouple the drive device () from the drive element ().

Infusion device for administering a medical fluid to a patient

An infusion device () for administering a medical fluid to a patient (P) comprises a pumping mechanism () configured to act onto a fluid conduit (), the pumping mechanism () comprising a pumping section () movable with respect to said fluid conduit () for causing a fluid flow (F) through said fluid conduit (). The pumping mechanism () comprises a multiplicity of rotatable gear elements (A-E) coupled to the pumping section () at a multiplicity of different locations (A-E), wherein the gear elements (A,E) are operatively coupled to each other for a coordinated rotation of the gear elements (A-E) for moving the pumping section (). 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.

Medical device having a detachable cover element A medical device () for administering a medical solution to a patient comprises a housing (), a receptacle () for receiving a pumping apparatus () for administering the medical solution to the patient, and a cover element () for covering the receptacle (). The cover element (), in a connected state, is pivotably connected to the housing () about a pivot axis (P) by means of a hinge connection, the hinge connection being releasable for detaching the cover element () from the housing (). In this way a medical device is provided which may have an increased adjustability for use in different environments in a healthcare environment.

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.

An infusion device () for acting onto a tube set () to transport a medical fluid through the tube set () comprises a first housing element () constituted to receive a tube section () of the tube set () and a second housing element () being movable with respect to the first housing element () such that, in a closed position of the second housing element (), the first housing element () and the second housing element () are constituted to receive the tube section () in between each other. A sensor device () is arranged on the first housing element () and having a sensor element () for measuring a force on the tube section () of the tube set (). Herein it is provided that the sensor device () is arranged on the first housing element () in an elastically displaceable manner, wherein the sensor device () is supported on the first housing element () via at least one spring element (). In this way an infusion device is obtained which may be less prone to variations in the squeezing of a tube section in between the sensor element and a movable housing element, potentially reducing the effort for calibrating infusion devices and increasing the reliability of pressure measurements on a tube section.

For controlling the movement of the push device of a pump of the syringe driver-type, the pump comprising a casing (), a syringe cradle () for a syringe (), a push device () mobile relative to the casing () and capable of being driven in rotation parallel to the longitudinal axis of the syringe by driving means, clutch means () for engaging or disengaging the push device on the driving means, the push device is disengaged from the driving means, in order to move it manually, and the presence or absence of a contact between the push device and the syringe head is determined. If the push device is not in contact with the syringe head, it is advanced manually. Blocking of the advance movement of the push device is triggered only if, at the beginning, the push device was not in contact with the syringe head.

Anti-bolus control method and corresponding device

The invention concerns a tube pump comprising a cradle () with a cavity () suitable for the accommodation of a tube clamp (). It further concerns a tube clamp () for a flexible tube, the tube clamp being suitable for accommodation in a tube pump, the tube clamp having a mobile part and an immobile part () designed to penetrate at least partly into a housing () realized in the tube pump. The invention also concerns a perfusion set. Finally, the invention concerns a system comprising a tube pump and a tube clamp. In order to provide a system comprising a tube pump and a tube clamp with improved operation safety, the tube pump has a cavity () with at least one protrusion () and the tube clamp () has means () for snapping attachment of the tube clamp behind the protrusion (). This arrangement allows to fix the tube clamp () safely in the cavity () and to give furthermore a feedback to the user because he feels (and he might in addition hear) that the tube clamp has snapped behind the protrusion. A further advantage resides in the fact that the solution according to the present invention can be put in place without significantly increasing the costs of the parts involved in the invention.
