1. A medical device comprising:
a module comprising:
a switch configured to detect an actuation action of a medical device, the actuation action causing the medical device to eject at least a portion of a medicament in the medical device, and
an electric unit connected to the switch and configured to store and/or provide information related to the detected actuation action;
a housing;
a dosage knob configured for rotation relative to the housing during dose dialing and configured not to rotate relative to the housing during dose injection; and
a dose dial sleeve,
wherein the medical device is an injection device,
wherein the module is attached to the dosage knob,
wherein during the dose dialing, the dosage knob and the dose dial sleeve are stationary relative to one another, and during the dose injection, the dose dial sleeve rotates relative to the dosage knob, and
wherein a relative rotational movement between the dose dial sleeve and the dosage knob is detected by the module during the dose injection.
