Abstract
A system is presented including a monitoring device and a medicament delivery device, where the monitoring device is configured to be releasably connected to the medicament delivery device and wherein the monitoring device comprises an induction sensor configured to detect a state of an electrically conductive drive member of the medicament delivery device in an medicament delivery process through an electrical current which is generated by a magnet field by the induction sensor on the electrically conductive drive element.

A system comprising a monitoring device and a medicament delivery device wherein the monitoring device is configured to be releasably connected to the medicament delivery device, wherein the monitoring device comprises an elongated sleeve defining a cavity for the medicament delivery device, and wherein the monitoring device comprises an induction sensor configured to detect a state of an electrically conductive drive element of the medicament delivery device in a medicament delivery process through an electrical current which is generated by a magnet field by the induction sensor on the electrically conductive drive element, wherein the electrically conductive drive element is a hollow tubular plunger configured to change state from a start state to a final state that partially contains a coil spring that changes from a compressed state to a relaxed state and wherein the induction sensor is configured to detect the absence or presence of the electrically conductive drive element in a sensing area.
A medicament delivery system comprising:
- an injection device comprising a hollow tubular plunger that is electrically conductive, partially contains a coil spring that changes from a compressed state to a relaxed state, and is biased in a start state and movable from the start state to a final state;
- a monitoring device releasably connected to a housing of the injection device, wherein the monitoring device comprises an elongated sleeve defining a cavity for the medicament delivery device, and where the monitoring device comprises:
- an induction sensor that detects movement of the hollow tubular plunger from the start state to the final state through an electrical current which is generated by a magnet field by the induction sensor, wherein the induction sensor detects an absence or presence of either the hollow tubular plunger or the coil spring in a sensing area as the hollow tubular plunger moves from the start state to the final state.
