Abstract

Average blood pressure data of a morning time zone of every week and average blood pressure data of a night time zone of every week calculated by an average calculation portion are stored in a memory by performing blood pressure measurement. An every-week processing portion alternately switches and displays the average blood pressure data of the morning time zone and the average blood pressure data of the night time zone read from the memory based on an instruction input through an operation unit on a display unit every three seconds, or the like.

First claim

The invention claimed is:

1. A blood pressure measurement device comprising:
a cuff to be attached to a measurement site of a living body;
a control unit that calculates a blood pressure while adjusting pressure of the cuff for blood pressure measurement;
a storage unit that stores morning blood pressure data for a plurality of days measured in a time zone corresponding to morning, and night blood pressure data for a plurality of days measured in a time zone corresponding to night calculated by the control unit;
a display unit;
a display operation unit having a single switch manually operated by a user to control the display unit;
a display processing unit that reads out data from the storage unit and displays the read data on the display unit; and
a central processing unit (CPU) that controls the control unit, the storage unit, the display unit and the display processing unit,
wherein the display processing unit calculates, by a control of the CPU, an average of the morning blood pressure data of each week for a plurality of weeks,
wherein the display processing unit calculates, by the control of the CPU, an average of the night blood pressure data of each week for a plurality of weeks,
wherein the display processing unit provides a first instruction to the display unit to display, by the control of the CPU, alternately with a first predetermined time interval, the average of the morning blood pressure data and the average of the night blood pressure data both belonging to one predetermined week,
wherein, in response to a manual operation of the single switch at a time when the average of the morning blood pressure data of said one predetermined week is being displayed by the display unit, the display processing unit provides a second instruction to the display unit to display, by the control of the CPU, alternately with a second predetermined time interval, and starting from the average of the morning blood pressure data of a week that is one week next to said one predetermined week, the average of the morning blood pressure data belonging to the week that is next to said one predetermined week, and the average of the night blood pressure data belonging to the week that is one week next to said one predetermined week, and
wherein, in response to a manual operation of the single switch at a time when the average of the night blood pressure data of said one predetermined week is being displayed by the display unit, the display processing unit provides a third instruction to the display unit to display, by the control of the CPU, alternately with a predetermined time interval, and starting from the average of the night blood pressure data of the week that is one week next to said one predetermined week, the average of the night blood pressure data belonging the week that is next to said one predetermined week, and the average of the morning blood pressure data both belonging to the week that is one week next to said one predetermined week.

2. The blood pressure measurement device according to claim 1 , wherein the display processing unit displays, by the control of the CPU, information indicating that a blood pressure value of the average of the morning blood pressure data belonging to the week that is next to said one predetermined week corresponds to a category of early morning high blood pressure on a same screen as a display screen of the average of the morning blood pressure data belonging to the week that is next to said one predetermined week when displaying the average of the morning blood pressure data belonging to the week that is next to said one predetermined week.

3. The blood pressure measurement device according to claim 2 , wherein the display processing unit displays, by the control of the CPU, information indicating that the blood pressure value of the average of the morning blood pressure data belonging to the week that is next to said one predetermined week corresponds to the category of early morning high blood pressure on the same screen as a display screen of the average of the night blood pressure data belonging to the week that is next to said one predetermined week when displaying the average of the night blood pressure data belonging to the week that is next to said one predetermined week.

4. The blood pressure measurement device according to claim 1 , wherein the display processing unit displays, by the control of the CPU, a blood pressure indicated by the average of the morning blood pressure data or the average of the night blood pressure data with a rectangular bar sectionalized by a plurality of segments of a predetermined unit, and simultaneously, with a numerical value in the same screen of the display unit.

5. The blood pressure measurement device according to claim 4 , wherein, by control of the CPU, a criterion value indicating the predetermined blood pressure section is displayed in association at a position indicating a blood pressure value corresponding to the criterion value on the bar.

6. The blood pressure measurement device according to claim 1 ,
wherein the storage unit further stores a detection result of whether the average of the morning blood pressure data corresponds to a category of early morning high blood pressure based on a comparison between the average of the morning blood pressure data belonging to a week that is one week next to said one predetermined week and an index of predetermined data characteristic of high blood pressure, and
wherein when the detection result corresponds to the category of early morning high blood pressure, the display unit displays, by control of the CPU, an indicator of the detection result simultaneously with the average of the night blood pressure data belonging to the week that is one week next to said one predetermined week during the alternate display of the average of the morning blood pressure data and the average of the night blood pressure data belonging to the week that is one week next to said one predetermined week.

7. The blood pressure measurement device according to claim 1 , wherein the display processing unit provides a fourth instruction to the display unit to display, by control of the CPU, a week indicator showing a number of weeks prior to said one predetermined week.
