Blood Pressure Apparatus Posture Detection Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional upper arm type blood pressure measurement apparatuses with automatic cuff winding mechanisms face challenges in maintaining accurate measurements due to variations in cuff winding strength and user posture, leading to incorrect blood pressure readings, especially when the elbow rest is not properly aligned with individual arm thickness and shape differences.
Innovation Solution
A blood pressure measurement apparatus equipped with an arm rest and elbow rest surface, featuring flexure detection means to identify downward flexure and inform the user of bad posture through an informing mechanism, ensuring proper alignment and consistent cuff compression for accurate readings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an elbow rest is provided to reduce loads on the user, then ease of operation is improved, but measurement precision deteriorates due to excessive force application and incorrect posture
Solution Approach 1:
The patent employs feedback mechanisms including a load cell to detect excessive force applied to the elbow rest and a sensor to detect arm position. When incorrect posture or excessive force is detected, the system provides visual or auditory feedback to guide the user to correct their posture, thereby maintaining measurement precision while preserving ease of operation through the elbow rest support.
2Ease of operation
If the cuff winding mechanism is made automatic to eliminate complicated winding operations, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent implements a self-service automatic cuff winding mechanism that automatically winds the cuff around the user's arm without manual intervention. The system uses sensors to detect arm insertion and automatically controls the winding process, eliminating the need for complicated manual winding operations while accepting increased device complexity to achieve this automation.
3Adaptability or versatility
If the elbow rest is positioned to accommodate individual arm differences, then adaptability is improved, but device complexity increases due to additional detection and adjustment mechanisms
Solution Approach 1:
The patent employs dynamic adjustment mechanisms that allow the elbow rest position to be automatically adjusted based on sensor detection of the user's arm characteristics. The system dynamically adapts the elbow rest position to accommodate individual arm thickness and shape differences, improving adaptability while using automated control to manage the complexity of the adjustment mechanism.

AI summary
A blood pressure measurement apparatus detects a downward flexure of an arm rest and informs a user of the downward flexure on a display unit. By providing a partially color changing display or a blinking display on the display unit, the user is informed that a measurement posture is not good. The blood pressure measurement apparatus has an elbow rest with an arrangement that can easily prompt the user to be in a good posture for measurement.
