Sphygmomanometer Schedule Adjustment for Sleep Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sphygmomanometers face challenges in performing nighttime blood pressure measurements for individuals with varying sleep schedules, leading to potential continuous measurement and increased physical burden on the subject, as traditional methods overlap with or are close to sleep times.
Innovation Solution
A sphygmomanometer with a nighttime blood pressure measurement mode that automatically adjusts the measurement schedule to include both a predetermined time and a time interval from sleep onset, using a control unit to disable or adjust the start times of measurements to prevent overlap, thereby providing idle time and reducing physical burden.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If blood pressure measurement is performed at both a predetermined time and a predetermined time interval from sleep onset to support various lifestyles, then adaptability to different sleep schedules is improved, but the risk of continuous measurement and physical burden increases
Solution Approach 1:
The measurement schedule is made dynamic by automatically adjusting between fixed-time measurements and interval-based measurements from sleep onset. The system adapts the measurement timing based on detected sleep patterns, transitioning between measurement modes to prevent overlapping while maintaining flexibility for different lifestyles.
Solution Approach 2:
The system uses feedback from sleep detection functionality to determine appropriate measurement timing. By monitoring when the subject actually falls asleep, the system adjusts the second type of measurement schedule to avoid continuous measurement, creating a closed-loop control that prevents physical burden while maintaining adaptability.
2Reliability
If blood pressure measurement is continuously performed when measurement schedules overlap, then measurement precision and reliability are improved, but sleep disturbance and physical burden increase
Solution Approach 1:
The system performs preliminary detection of sleep onset time and uses this information to pre-adjust the measurement schedule before overlapping occurs. By anticipating potential schedule conflicts based on detected sleep patterns, the system prevents continuous measurement before it can disturb sleep or cause physical burden.
Solution Approach 2:
The sleep detection functionality acts as an intermediary between the two measurement scheduling methods. It provides intermediate information about actual sleep timing that mediates between the fixed predetermined time schedule and the interval-based schedule, allowing the system to harmonize them and avoid conflicts.

AI summary
A sphygmomanometer includes a first type schedule, a second type schedule, and a control unit that disables one of first blood pressure measurement scheduled based on the first type schedule and second blood pressure measurement scheduled based on the second type schedule or changes a start time of the scheduled first blood pressure measurement or a start time of the scheduled second blood pressure measurement to provide idle time between the first blood pressure measurement and the second blood pressure measurement in a case where a time zone of the scheduled first blood pressure measurement and a time zone of the scheduled second blood pressure measurement at least partially overlap with each other or in a case where a time difference between the time zone of the first blood pressure measurement and the time zone of the second blood pressure measurement is equal to or less than a predetermined value.
