Blood Pressure Display Bar Graph Time Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional devices for displaying blood-pressure-related information fail to easily calculate and display the average blood pressure value over a plurality of days at specific times, especially at night, due to the lack of distinction between blood pressure measurements taken at different times.
Innovation Solution
A device and method for displaying blood-pressure-related information that includes a data input unit for receiving blood pressure value data, a storage unit for storing the data, and a display unit that sets date and time in a horizontal direction and blood pressure in a vertical direction, displaying blood pressure values as a bar graph, and allowing users to designate specific times to calculate and display systolic and diastolic blood pressure average values for those times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If blood pressure measurements at multiple times are displayed together without distinction, then the display is simple, but the accuracy of average blood pressure calculation at specific times deteriorates
Solution Approach 1:
The patent segments blood pressure data by measurement time points, organizing them into distinct groups. The display unit presents bar graphs for each specific time (e.g., 2:00 AM, 3:00 AM, 4:00 AM) separately, allowing accurate calculation of average blood pressure at each time point while maintaining a simple overall display structure.
2Loss of information
If blood pressure data for multiple days and times are stored and processed, then the information completeness improves, but the device complexity increases
Solution Approach 1:
The patent adds time as a dimensional parameter to organize blood pressure data, displaying it along the horizontal axis while maintaining measurement values on the vertical axis. This dimensional approach allows comprehensive storage and processing of multi-day, multi-time data without increasing device complexity, as the structure naturally accommodates the additional information layer.
3Adaptability or versatility
If average blood pressure values at specific times are calculated and displayed, then the usefulness for cardiovascular risk assessment improves, but the calculation complexity increases
Solution Approach 1:
The calculation unit automatically computes average blood pressure values at each specific time point by itself, without requiring manual intervention. When a user designates a specific time, the system autonomously retrieves relevant data, performs the averaging calculation, and displays the result, making the system adaptable for cardiovascular risk assessment while keeping the operational process simple.

AI summary
In the present invention, date and time are set in a horizontal direction and blood pressure is set in a vertical direction on a display screen, and a change in a blood pressure value over a display target period is displayed as a bar graph with vertical bars each formed by connecting SBP and DBP for each time and arranged in the horizontal direction. When a position corresponding to a vertical bar at a specific time on the display screen is designated with a pointing device, blood pressure value data measured for each day at the specific time are averaged over the display target period to obtain a systolic blood pressure average value and/or a diastolic blood pressure average value, according to the position designated. The obtained systolic blood pressure average value and/or diastolic blood pressure average value is displayed together with the bar graph on the display screen.
