Catheter Rendering Error Correction via ECU Signal Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Catheter rendering issues during medical procedures, such as those for heart arrhythmia treatment, often result in incorrect connections between catheter pins and sockets, leading to incorrect rendering on display devices, which are not immediately detectable until the catheter is placed within a patient, causing procedural delays and frustration.
Innovation Solution
An electronic control unit (ECU) is integrated into the system to determine and correct catheter rendering errors by identifying incorrectly connected electrodes and automating the troubleshooting process, ensuring proper connection and rendering of the catheter on the display device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual connection checking is performed during initial setup, then connection accuracy may be improved, but the setup time and complexity increase
Solution Approach 1:
The system performs preliminary detection of connection status between catheter pins and sockets before the medical procedure begins. The ECU checks the electrical continuity and mapping between pins and sockets in advance, identifying any incorrect connections during the setup phase rather than during the actual procedure, thus preventing delays later while ensuring accurate connections.
Solution Approach 2:
The ECU provides real-time feedback about the connection status between catheter pins and sockets. The system monitors the electrical signals from each pin and compares them against the expected socket assignments, alerting operators to any mismatches immediately. This continuous feedback mechanism ensures high connection accuracy without requiring time-consuming manual verification of each connection.
2Measurement precision
If manual troubleshooting of rendering issues is performed, then detection accuracy may be improved, but the procedural time and complexity increase
Solution Approach 1:
The ECU automatically detects and diagnoses rendering issues by monitoring the electrical continuity between catheter pins and sockets. Instead of requiring medical personnel to manually troubleshoot rendering problems, the system self-diagnoses connection status by analyzing signal patterns and comparing them against expected configurations, thereby maintaining high detection accuracy while reducing procedural complexity.
Solution Approach 2:
The system replaces manual mechanical troubleshooting with automated electronic detection. The ECU uses electrical signal analysis and digital processing to identify connection errors, substituting the need for manual inspection and testing. This electronic substitution maintains precise detection of rendering issues while eliminating the complexity of manual troubleshooting procedures.
3Ease of operation
If connection verification is delayed until catheter placement, then procedural setup is simplified, but procedural delays occur when issues are detected
Solution Approach 1:
The system performs connection verification as a preliminary step during catheter setup, before the catheter is placed in the patient. The ECU checks all pin-to-socket connections and validates the rendering configuration in advance, ensuring that any issues are resolved during setup rather than during the procedure. This preliminary verification maintains operational simplicity while preventing procedural delays.
4Speed
If automated detection systems are implemented, then detection speed is improved, but device complexity increases
Solution Approach 1:
The ECU is designed as a multi-functional unit that performs multiple tasks: it manages catheter control, monitors electrical signals, detects connection status, and controls rendering display. By consolidating these functions into a single universal controller, the system achieves fast automated detection of connection issues without proportionally increasing overall system complexity, as the ECU already handles various operational functions.
