A modular device for administering a fluid medicament fixable to the skin of a user includes a reservoir module with a reservoir defining a first axis, a first connecting structure and a first electrical contact arrangement; and a pump module with a piston rod defining a second axis, a second connecting structure arranged around the piston rod, and a second electrical contact arrangement. The first and second connecting structures are plugged together and the first axis and the second axes lie on a common axis forming a rotational axis. The pump module is rotated relative to the reservoir module about this rotational axis to electrically connect the first and second electrical contact arrangements. The first contact arrangement is displaced radially farther from the first axis than the first connecting structure, and the second electrical contact arrangement is displaced radially farther from the second axis than the second connecting structure.

Modular administration appliance

An infusion apparatus for delivering medication includes a housing, a drive mechanism, a force sensor, and a transfer element. The drive mechanism comprises first and second conveying elements, the second conveying element for advancing a plug in a reservoir in the distal direction, the first conveying element with limited axial movement relative to the housing but rotatable to cause an ejecting or resetting movement of the second conveying element. The force sensor is arranged along a central axis between the housing and the proximal end of the drive mechanism. The transfer element is axially arranged between the force sensor and the first conveying element and the force sensor bears axial forces exerted by the ejection movement. The second conveying element moves the transfer element away from the first conveying element against the bias of a restoring force such that the force sensor bears axial forces exerted by the resetting movement.

Device for administering a fluid product

An insertion mechanism for a cannula includes a cannula housing, a displaceable cannula, at least one cannula holder, an insertion spring, a triggering element, and a safety device. The safety device, in a secured state, holds the triggering element in a blocked position against a force of the insertion spring and, in a released state, releases the triggering element such that the triggering element is movable into a release position by the force of said insertion energy store and the at least one cannula holder is able to move relative to the cannula housing, driven by the insertion energy store, so as to trigger or implement an insertion movement or insertion. To reach the released state, the safety mechanism is heatable by a heating element and softened and/or weakened with respect to its mechanical carrying or holding capacity, or severed or at least partially or completely melted.

Cannula insertion mechanism

A disposable module that can be coupled to a reusable module in order to form a pump for dispensing a medicament substance to a user in a metered manner in a coupled state, comprising a housing that encases the following components: a reservoir for receiving the substance to be dispensed; and at least one extensible cannula, which is fluidically connected to the reservoir either after being inserted or in a permanent manner. The disposable module may also comprise an electrical energy store, wherein the electrical energy necessary for the reusable module can be obtained both from the disposable module and also from a rechargeable battery in the reusable module, in order to ensure redundancy of the energy necessary for the reusable module.

Patch pump

A coupling mechanism for a medication delivery device includes a first part axially fixed relative to a housing and rotatable around a longitudinal axis of the first part, the first part having a gearing engagement to a second part arranged along the longitudinal axis, the gearing engagement having a first frictional resistance. The second part axially moveable along the longitudinal axis, and directly or indirectly in a friction fit engagement with the housing, which has a second frictional resistance. The first frictional resistance being below the second frictional resistance such that a rotation of the first part in a first direction axially longitudinally moves the second part away from the first part and a rotation in a second direction, opposite to the first rotation direction, reduces the axial distance between the first and second part and/or axially moves the second part into coupling abutment with the first part.

Coupling mechanism for a medication delivery device

Disclosed is a measuring bridge arrangement containing: a measuring bridge comprising at least one first half bridge having a first measuring connection and a second half bridge having a second measuring connection; a reference voltage divider having at least one first and a second test connection; a differential amplifier having at least one first and a second amplifier input and at least one amplifier output, a voltage amplification, and having an output voltage working range. In the arrangement, the first amplifier input is wired to a first capacitor and the second amplifier input is wired to a second capacitor, and the amplifier inputs can be selectively connected to the measuring connections or to the test connections.
