Solution Overview
Problem
Current ECG systems face inaccuracies in respiratory data measurement due to low signal amplitude and motion artifacts, and the transition between different ECG configurations is cumbersome, time-consuming, and uncomfortable for patients, leading to increased costs and human error.
Innovation Solution
A system with distinct ECG wires and a respiratory wire, using a removable/passthrough connector to isolate cardiac and respiratory electrical activities, and positioning electrodes for optimal signal capture, allowing for flexible configuration between 5-lead, 6-lead, and 12-lead setups without full electrode reapplication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If respiratory data is measured using the same electrodes as ECG data, then device complexity is reduced, but measurement precision deteriorates due to low signal amplitude and motion artifacts
Solution Approach 1:
The patent divides the measurement function into separate components by using distinct electrodes for ECG and respiratory measurements. The ECG electrodes are positioned on the chest for cardiac monitoring, while separate respiratory electrodes are placed on the abdomen and lower chest to specifically capture respiratory electrical activity, thereby improving measurement precision for each physiological parameter
Solution Approach 2:
The patent introduces an intermediary processing stage where respiratory electrical activity is measured separately from cardiac activity. The respiratory wire and electrodes act as an intermediary channel dedicated to respiratory monitoring, isolating the low-amplitude respiratory signals from the higher-amplitude cardiac signals to improve measurement accuracy
2Measurement precision
If ECG configurations are changed by reapplying electrodes, then measurement precision is maintained, but loss of time increases due to the cumbersome transition process
Solution Approach 1:
The patent creates a universal electrode setup where the same set of electrodes can serve multiple ECG lead configurations (5-lead, 6-lead, 12-lead). The electrodes are strategically positioned to capture electrical activity from multiple perspectives, allowing the system to switch between different monitoring configurations without requiring electrode reapplication, thus reducing time loss while maintaining measurement precision
Solution Approach 2:
The patent implements preliminary positioning of electrodes in locations that are optimal for multiple ECG configurations. By pre-positioning electrodes to capture electrical activity from various angles and positions, the system enables rapid switching between 5-lead, 6-lead, and 12-lead configurations without requiring time-consuming reapplication, thereby reducing loss of time while preserving measurement precision
3Measurement precision
If ECG configurations are changed by reapplying electrodes, then measurement precision is maintained, but ease of operation deteriorates due to patient discomfort and human error
Solution Approach 1:
The patent designs a universal electrode arrangement that can accommodate multiple ECG lead configurations (5-lead, 6-lead, 12-lead) without requiring reapplication. The electrodes are positioned to serve multiple functions simultaneously, making the system easy to operate by allowing clinicians to switch between monitoring modes without disturbing the patient or risking reapplication errors, thereby improving ease of operation while maintaining measurement precision
