The present invention refers to a medical device (100) comprising a measurement unit (110) adapted to measure a value of a physiological parameter, for example a blood glucose level, a data storage (130) adapted to store a plurality of measurement values of the physiological parameter, for each measurement value an associated event tag, for each measurement value an associated time stamp, for each at least one predefined event an associated current time range for tagging preselection, a processor (140) adapted to receive from the measurement unit (110) or from the data storage (130) a new measurement value with an associated time, Comparing the associated time stamp of the new measurement value with the stored at least one time range for tagging preselection, If the time stamp is within one current time range for tagging preselection the corresponding tag of the predefined event is preselected and initiated for user confirmation, In case one particular predefined tag of one particular predefined event is then selected and confirmed with regard to the new measurement value, the associated time stamps of a predefined number of consecutive recent measurement values tagged with the one particular predefined event is received from a data storage (130), Calculate a new time range for tagging preselection for the one predefined event at least partly based on the associated time stamps of the predefined number of consecutive recent measurement values and on the associated time stamp of the new measurement value, preferably only if at least one validation criterion is met, and Initiate storing the new time range as current time range for tagging preselection for the one particular predefined event in the data storage (130), preferably only if the at least one validation criterion is met. The invention further refers to a corresponding method and computer program for operating a medical device as well as to a corresponding computer program product.本發明係一種醫療裝置包含測量單元適合測量生理參數
