Blood Pressure Monitor With Snore Detection For Sleep Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blood pressure measurement devices during sleep often record inaccurate readings due to external factors like snoring and coughing, and it is challenging to determine if abnormal readings are caused by underlying health issues or external noises without real-time observation.
Innovation Solution
A blood pressure measurement device with a sound detection function that includes a microphone to detect sounds like snoring, coughing, and teeth grinding, which are associated with blood pressure measurements, allowing for temporal recording of these sounds alongside blood pressure data to identify factors affecting measured values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional blood pressure measurement devices are used during sleep, then blood pressure can be measured continuously, but the measured values become inaccurate due to external factors like snoring and coughing
Solution Approach 1:
A microphone is introduced as an intermediary device to detect body sounds (snoring, coughing, etc.) that occur during sleep. The microphone captures acoustic signals that indicate when the subject is making body sounds, and this information is used to identify and exclude inaccurate blood pressure measurements from the final results, thereby resolving the contradiction between continuous measurement and measurement accuracy.
2Measurement precision
If real-time observation is performed to determine if abnormal readings are caused by external noises, then measurement accuracy can be improved, but the complexity of the system increases
Solution Approach 1:
The system performs self-diagnosis by automatically detecting body sounds through the microphone and using this information to identify inaccurate measurements. The device autonomously determines which blood pressure readings are affected by external factors without requiring external observation or manual intervention, thereby improving accuracy while maintaining relatively simple system complexity.
3Loss of information
If continuous blood pressure monitoring is performed during sleep, then health information can be gathered, but power consumption increases
Solution Approach 1:
Instead of continuous operation, the blood pressure measurement and sound detection are performed periodically at predetermined intervals during sleep. This periodic measurement approach allows the device to gather sufficient health information over time while significantly reducing power consumption compared to continuous monitoring, as the measurement system can enter low-power states between measurements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables accurate identification of factors influencing blood pressure readings, facilitating diagnosis by correlating snoring and other body sounds with blood pressure data, reducing power consumption, and allowing for long-term, uninterrupted measurements without restricting subject movement.
Implementation Method 1
a sound detection unit for detecting a body sound of the subject during blood pressure measurement by the blood pressure measurement unit
Data Source
AI summary
A blood pressure measurement device measures a blood pressure of a subject by a blood pressure measurement unit, detects a body sound of the subject during blood pressure measurement by a sound detection unit. The measured blood pressure and the detected body sound are recorded in association with each other by time information. The factor for the increase of measured blood pressure value can be specified by showing the chronological blood pressure measurement result along with checking the presence or absence of a body sound such as snoring etc.
