Abstract

A blood pressure measurement unit measures the blood pressure and a CPU accordingly stores, in a blood pressure storage unit, measurement data as well as time information regarding the time at which the blood pressure is measured. The CPU calculates, as representative measurement data, the average of a plurality of measurement data stored in the blood pressure storage unit and correlated with the time information indicating a time in the range between nine weeks ago and ten weeks ago, correlates the representative measurement data with time information representing the corresponding week and stores the data with the time information in the blood pressure storage unit. At this time, the CPU deletes from the blood pressure storage unit those measurement data based on which the representative measurement data is calculated.

Claims

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 relative to the time indicated by said time information correlated with the measurement data; and

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.

2. The electronic blood pressure monitor according to claim 1, further comprising 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.

3. The electronic blood pressure monitor according to claim 1, wherein

the length of time between said first past time threshold and said second past time threshold is substantially one week.

4. The electronic blood pressure monitor according to claim 1, wherein

the length of time between said first past time threshold and said second past time threshold is substantially one month.

5. The electronic blood pressure monitor according to claim 1, wherein

said representative measurement data calculation means calculates, as said representative measurement data, average of said plurality of measurement data.

6. The electronic blood pressure monitor according to claim 1, wherein

said time information includes day-of-week information indicating a day of a week, and

days of a week are divided into a plurality of day groups each including at least one day of the week, and said representative measurement data calculation means calculates, for each of said day groups, representative measurement data representing said plurality of measurement data correlated with said time information including said day-of-week information indicating any day included in said day group.

7. The electronic blood pressure monitor according to claim 6, wherein

said plurality of day groups include a day group including at least one of Monday to Friday.

8. The electronic blood pressure monitor according to claim 6, wherein

said plurality of day groups include a day group including at least one of Saturday and Sunday.

9. The electronic blood pressure monitor according to claim 1, wherein

said time information includes hour/minute information indicating hour/minute at which measurement is performed by said blood pressure measurement means, and

one day is divided into a plurality of time periods each defined by a starting hour/minute and an ending hour/minute, and said representative measurement data calculation means calculates representative measurement data representing said plurality of measurement data correlated with said time information including said hour/minute information indicating any hour/minute included in at least one of said time periods.

10. The electronic blood pressure monitor according to claim 1, wherein

said second past time threshold is larger than said first past time threshold,

said electronic blood pressure monitor further includes display means for displaying data, said display means having a measurement display mode for displaying said measurement data taken when blood pressure is measured by said blood pressure measurement means and a reading display mode for displaying contents read from said storage means, and

said reading display mode has a display mode for displaying said measurement data correlated with said time information indicating a time smaller in value than said first past time threshold, and a display mode displaying said representative measurement data.

11. A method of managing measurement data of an electronic blood pressure monitor comprising the steps of:

storing, in a memory, provided measurement data of blood pressure and time information correlated with the measurement data;

measuring blood pressure to output, to said memory, said measurement data obtained by measuring the blood pressure and said time information indicating time at which the blood pressure is measured;

calculating representative measurement data representing a plurality of said measurement data stored in said memory, 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 relative to the time indicated by said time information correlated with said measurement data; and

supplying representative information for outputting to said memory the representative measurement data calculated by said step of calculating the representative measurement data and said time information indicating time according to at least one of said first past time threshold and said second past time threshold.
