Abstract
An injection device including at least one sensor for detecting an operating process of the injection device, an electronic circuit connected to the sensor for establishing the beginning and elapsed time of a service life, based on one or more sensor signals, and an output device connected to the circuit for providing a signal indicating the end of the service life. The invention encompasses a method for determining a service life of an injection device, wherein the beginning of the service life is established by one or more sensors for detecting an operating process of the device, a signal is generated which signals the end of the service life, and at least one of an optical, acoustic or tactile output device is associated with the injection device for providing a signal which indicates the end of the service life.
