Four-Limb Blood Pressure Rectangular Plotting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional devices for evaluating arterial disease primarily focus on presenting blood pressure ratios, failing to intuitively display blood pressure values and their relationships with other measurement values, which limits effective evaluation of arterial health.
Innovation Solution
A bioinformation outputting device and method that plots blood pressure values from four limbs on linear axes in a two-dimensional region, forming a rectangle to visually represent the relationships between these values, allowing for intuitive recognition of specific measurements and relationships.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional devices present only blood pressure ratios, then the evaluation of arterial disease is simplified, but the intuitive recognition of specific blood pressure values and their relationships is lost
Solution Approach 1:
The patent transforms the conventional one-dimensional presentation of blood pressure ratios into a two-dimensional graphical display. Blood pressure values from four limbs are plotted on orthogonal axes, creating a spatial representation where relationships between values become visually apparent through geometric patterns and relative positions, thereby preserving information while maintaining evaluation simplicity.
2Loss of information
If blood pressure values are plotted on multiple axes in a two-dimensional region, then the relationships between measurements are intuitively recognized, but the device complexity increases
Solution Approach 1:
The patent employs a universal coordinate system framework that can accommodate blood pressure values from multiple limbs simultaneously. The same graphical display mechanism handles different measurement scenarios (single limb, bilateral comparison, progression tracking) without requiring separate presentation methods, thereby managing complexity through a unified approach that preserves complete information.

AI summary
Blood pressure values measured in four limbs are plotted on first to fourth linear axes which extend from an origin in an upper right direction, an upper left direction, a lower left direction, and a lower right direction respectively, and a rectangle composed of vertices which are determined by the plotted blood pressure values is illustrated to present the blood pressure values. This allows a specific measured value in each site to be easily known, and the relationships between the blood pressure values in the four limbs are intuitively understood from the shape of the rectangle.
