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

A piercing device for an administration device includes an elastic element with which a biasing force may be generated for piercing, a base, and a cannula unit which may be movable relative to the base in a piercing direction from a safety (secured) position, where the cannula unit may be subjected to the biasing force in the piercing direction. The administration device further includes a securing element by which the cannula unit, subjected to the biasing force, may be held in the safety position and which has a thermosensitive region that may be deformable under mechanical stress when heated, and a heating element with which the thermosensitive region of the securing element may be heated, such that the thermosensitive region of the securing element may deform in response to the biasing force and, as a result, the cannula unit may move away from the safety position in the piercing direction.

Piercing device for an administration device

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.
