The present invention relates to a medical device (100), which comprises: a measurement unit (110) adapted to measure a value of a physiological parameter, for example a blood glucose level, and a data storage device (130). , ○ Multiple measurements of physiological parameters, ○ Associated event tag for each measurement, ○ Relevant time stamp for each measurement, ○ Relevance for tagging preselection for at least one given event A data storage device adapted to store the current time range； and a processor (140) that receives a new measurement value with an associated time stamp from the measurement unit (110) or data storage device (130). Compare the relevant timestamp of the new measurement with at least one stored time range for tagging preselection, If the imstamp is within one current time range for tagging preselection, the corresponding tag for a given event is preselected and fired for user confirmation； When one particular predetermined tag is then selected and confirmed with respect to a new measurement, the association between that one particular predetermined event and a predetermined number of consecutive recent measurements tagged A time stamp is received from the data storage device (130) and is based on at least in part the relevant time stamp of a predetermined number of consecutive recent measurements and the relevant time stamp of a new measurement Calculate a new time range for event tagging preselection, preferably only if at least one validation criterion is met, and ○ the new time range Start storing in the data store (130) as the current time range for tagging preselection of one particular predetermined event, preferably only if at least one validation criterion is met And a processor applied as described above. The present invention further refers to corresponding methods and computer programs for operating medical devices, and corresponding computer program products.本発明は医療デバイス（１００）に関し、この医療デバイスは、・生理学的パラメータ、たとえば血糖レベルの値を測定するように適用された測定ユニット（１１
