Abstract

The present Invention relates to an injection device capable of emitting a flashing light signal indicating the time elapsed since last ejection and/or the size of the last ejected dosage and/or a return signal indicating the operable state of the device and/or a time out signal indicating when the pen can be removed after ejecting of a dosage. The injection device comprises an electronic control circuit comprising: a sensor unit arranged to detect the occurrence of an ejection of a drug from the injection device; a timer for determining an approximate time elapsed since last ejection; a signal emitting device being able to emit a signal, the signal emitting device being controllable by the electric control circuit, so as to emit a time signal that varies with the time elapsed since last ejection.

First claim

The invention claimed is:

1. An injection device ( 102 ) comprising an electronic control circuit ( 126 , 152 ) comprising:
a dosage setting device for setting the dose to be injected;
a sensor unit arranged to detect the occurrence of an ejection of a drug from the injection device, by determining that a button of the dosage setting device is activated;
a timer ( 142 ) for determining an approximate time elapsed since completion of last ejection;
a signal emitting device ( 110 , 130 ) being able to emit a signal ( 114 ), the signal emitting device ( 110 , 130 ) being controllable by the electric control circuit, so as to emit a time signal that varies with the time elapsed since completion of last ejection,
wherein, the emitted time signal consists of a flashing light indicating the time elapsed since completion of last ejection, and wherein the frequency at which the flashing light flashes increases with the time elapsed since completion of last ejection.
