Abstract:
1. An electronic blood pressure monitor comprising: storage means for storing provided measurement data of blood pressure and time information correlated with the measurement data; blood pressure measurement means for measuring blood pressure to provide, to said storage means, said measurement data and said time information indicating time at which the blood pressure is measured; representative measurement data calculation means for calculating representative measurement data representing a plurality of said measurement data stored in said storage means, said plurality of measurement data each correlated with the time information indicating a time in a period between a predetermined first past time threshold and a predetermined second past time threshold earlier than said predetermined first past time threshold relative to the time indicated by said time information correlated with the measurement data; representative information supply means for outputting to said storage means the representative measurement data calculated by said representative measurement data calculation means and said time information indicating time reflecting at least one of said first past time threshold and said second past time threshold; and data deletion means for deleting from said storage means, when said representative measurement data is stored in said storage means, said plurality of measurement data based on which said representative measurement data calculation means calculates said representative measurement data, said storage means retaining, during said deleting by said data deletion means, said measurement data correlated with said time information indicating a time more recent than said first past time threshold, said representative measurement data calculation means increasing the time period between said first past time threshold and said second past time threshold as the time period increases between said calculation of said representative measurement data and said measurement of said measurement data used to calculate said representative measurement data.
