Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cardiac monitoring systems fail to accurately determine electrode placement on a patient's body, leading to incorrect electrocardiogram (ECG) readings when electrodes are positioned incorrectly, requiring manual correction by medical personnel.
Innovation Solution
A cardiac monitoring system that automatically identifies and corrects electrode positions using wireless or wired electrodes with position codes, signal profiling, and image analysis to ensure accurate ECG readings without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual correction of electrode placement is used, then electrode positioning accuracy can be improved, but medical personnel time and operational complexity increase
Solution Approach 1:
The system automatically detects and corrects electrode placement errors without requiring manual intervention. The processor compares received signal profiles with predetermined profiles, identifies mismatches, and autonomously determines corrective actions, allowing the system to serve itself rather than requiring medical personnel to manually verify and correct each electrode position.
Solution Approach 2:
The system implements a feedback mechanism where the processor continuously monitors ECG signal profiles, compares them against expected patterns, and uses the comparison results to identify and correct placement errors. This closed-loop feedback system automatically adjusts for positioning errors based on the electrical signal characteristics themselves.
2Reliability
If manual electrode placement verification is performed, then ECG reading accuracy improves, but device operation complexity increases
Solution Approach 1:
The system performs self-verification by automatically comparing received signal profiles with predetermined profiles and identifying placement errors without requiring external verification. The processor autonomously determines whether electrodes are correctly positioned based on signal characteristics, eliminating the need for manual verification steps.
Solution Approach 2:
The patent replaces manual mechanical verification processes with automated electronic signal analysis. Instead of requiring personnel to physically check electrode positions, the system uses electrical signal profile comparison to detect and correct placement errors, substituting electronic automation for manual mechanical inspection.
3Productivity
If automatic electrode position correction is implemented, then operational efficiency improves, but system complexity increases
Solution Approach 1:
The system uses feedback from ECG signal profiles to automatically detect and correct electrode placement errors. The processor compares received signals with predetermined profiles and uses this feedback information to identify mismatches and implement corrections, enabling automatic operation without requiring complex external verification systems.
Solution Approach 2:
The system creates and stores predetermined signal profiles that represent correct electrode placements. By comparing received signals against these stored reference profiles, the system can automatically identify placement errors without requiring complex real-time analysis, using simplified pattern matching against pre-established templates.

AI summary
A cardiac monitoring system that automatically determines whether one or more electrodes are placed at wrong positions on a person's body includes an ECG monitor. The electrodes are connected to the ECG monitor wirelessly or by wire. Each electrode includes a position code that corresponds to a body location where the electrode is to be placed. The signals that are transmitted from each electrode include the position code assigned to the electrode. The profile of the signals received from the electrodes are compared with expected profile of the signals from the electrodes that are placed at each specific position on the body. The position code in the transmitted data of any electrode that is determined to be placed at a wrong position is automatically replaced with the position code corresponding to the electrodes' actual position. The leads are then determined based on the electrode signals and the electrodes' position codes.
