An auxiliary module for connecting to an injector for dispensing a medical substance comprises a housing having a retaining device, and a receiving unit having a retaining element, wherein the receiving unit is movable relative to the housing. The auxiliary module includes a retaining configuration, in which the receiving unit is immovably retained in the housing by the retaining device, and in which the retaining element can cooperate with the injector in such a way that the injector is retained by the receiving unit and the retaining element is locked by the housing. The auxiliary module also includes a release configuration, in which the receiving unit is released from the retaining device and the injector is released from the retaining element. The auxiliary module can be adjusted from the retaining configuration into the release configuration, and back again, by an adjustment movement of the receiving unit.

Connection mechanism for an auxiliary module

Implementations relate to an electronic add-on module releasably attachable to an injection device prior to injection, a sensor element for detecting a state or process in the injection device, a processor element for evaluating and/or processing a signal of the sensor element, and an energy store for supplying the processor element with energy. The add-on module has a first module part, which is connectable along its longitudinal axis to the injection device in an axially fixed manner by means of a holding mechanism. A second module part is movable for a damped relative movement, such as a deceleration or braking movement, by a delay stoke with respect to the first module part connected to the injection device. By damping a relative movement between two module parts, the force transmission between the add-on module and the injection device is controlled and a maximum force surge is limited to the injection device.
