Abstract
An injection device comprises a pen (10) with a syringe (13) to be emptied. The dose expelled from the syringe is set by means of a dose setting device (17). For people with an impaired vision, the setting of the dose is rather difficult. Therefore, an external display apparatus (30) is provided that may be set to the pen (10). Via contacts (21) and counter contacts (34), information about the dose is transmitted to the display apparatus (30) and shown on a large display (32).
