Spider Chart Display for Anesthesia Depth Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical staff face challenges in quickly and accurately determining the depth of anesthesia due to the vast amount of information scattered across different monitors with inconsistent parameters, making it difficult to assess whether a suitable dose of anesthetic is administered.
Innovation Solution
A system and method for displaying clinical parameters using a spider chart that simultaneously displays at least three clinical parameters, such as awareness, muscle relaxation, and pain strength, with each parameter represented by a radial spoke indicating whether its value falls within, above, or below preset threshold ranges, facilitating a comprehensive and intuitive visualization of anesthesia depth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple single-parameter monitors are used to display different clinical parameters, then comprehensive monitoring information is provided, but the information is scattered and difficult to interpret quickly
Solution Approach 1:
The patent combines multiple single-parameter monitors into a single multi-parameter monitor that displays all clinical parameters (BIS, NMT, blood pressure, heart rate, blood oxygen) on one screen. This merging eliminates the need for doctors to view multiple separate monitors and combine information manually, directly resolving the contradiction by providing both comprehensive information and ease of interpretation simultaneously.
Solution Approach 2:
The patent introduces a spider chart visualization that adds a graphical dimension to parameter display. Instead of traditional numerical or waveform displays, parameters are represented as radial spokes on a spider chart, with spoke length indicating parameter values and color coding showing threshold compliance. This dimensional change makes complex multi-parameter information intuitively interpretable at a glance.
2Loss of information
If detailed parameter information is displayed on monitors, then comprehensive monitoring is achieved, but doctors spend more time choosing and analyzing parameters
Solution Approach 1:
The patent extracts the most critical information needed for anesthesia depth assessment from the full set of parameters and highlights it through the spider chart visualization. The spider chart selectively displays key parameters (BIS, NMT, and selected vital signs) with visual indicators that immediately show whether each parameter is within target ranges, allowing doctors to quickly grasp essential information without analyzing all available data in detail.
Solution Approach 2:
The patent uses color coding on the spider chart spokes to indicate whether parameter values are within, above, or below preset threshold ranges. This visual encoding allows doctors to instantly assess parameter compliance without numerical analysis, significantly reducing the time required for clinical judgment while maintaining complete information availability.
3Adaptability or versatility
If parameters from different manufacturers' monitors are displayed, then monitoring flexibility is improved, but parameter consistency and reliability are compromised
Solution Approach 1:
The patent creates a universal display interface that can integrate parameters from multiple manufacturer sources. The spider chart visualization serves as a manufacturer-agnostic presentation layer that standardizes how parameters are displayed and interpreted, ensuring consistent visual representation regardless of the source monitor manufacturer, thereby maintaining both versatility and reliability.
