Adjustable ECG Sensor Leadwire for Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ECG monitoring systems face issues with excessively long leadwires that hinder patient movement, cause entanglement, and introduce noise into recorded signals, as well as detachment during care operations.
Innovation Solution
The development of adjustable ECG sensors with leadwires that can be sized to fit exactly to the patient's electrode arrangement, featuring an adhesive for secure attachment and a connector system allowing electrical connection at multiple points along the leadwire, thereby eliminating excess length and noise issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If leadwires are made excessively long to accommodate all patient positions, then adaptability is improved, but patient movement is hindered and entanglement occurs
Solution Approach 1:
The leadwire length is made adjustable rather than fixed, allowing dynamic modification during patient care. The leadwire can be extended or shortened based on the patient's position and movement requirements, resolving the contradiction between adaptability and ease of movement.
Solution Approach 2:
The leadwire is divided into adjustable segments or sections that can be independently positioned and secured. This segmentation allows the leadwire to adapt to different patient body contours and positions while preventing entanglement through controlled positioning at multiple points.
2Adaptability or versatility
If leadwires are made excessively long to reach all electrode locations, then adaptability is improved, but signal noise is introduced
Solution Approach 1:
The leadwire length is dynamically adjusted to match the actual distance between the monitor and electrode, eliminating excessive length that would generate noise. This dynamic adjustment maintains adaptability while minimizing signal interference from overly long conductive paths.
Solution Approach 2:
The excessive portion of the leadwire is removed or trimmed after initial placement, extracting only the necessary length required for the specific patient configuration. This eliminates the noise-generating excess length while preserving the essential adaptability for different electrode arrangements.
3Adaptability or versatility
If leadwires are made excessively long to accommodate patient movement, then adaptability is improved, but detachment occurs during care operations
Solution Approach 1:
The leadwire length is made dynamically adjustable with securement mechanisms that can be positioned at different locations along the wire. This allows the leadwire to be shortened during care operations to prevent detachment while maintaining the ability to accommodate patient movement when extended.
Solution Approach 2:
The leadwire is segmented with multiple potential attachment points or secures locations along its length. This segmentation allows care providers to attach or secure the leadwire at optimal positions during different procedures, preventing detachment while maintaining adaptability for various patient positions.

AI summary
An adjustable ECG sensor is attachable to a patient to sense cardiac signals and includes an adjustable leadwire having a flexible substrate, a conductor extending along the flexible substrate, and a connector end connectable to a receiver associated with an ECG monitor. The adjustable ECG sensor further includes an electrode having an electrode pad, a clip connected to the electrode pad and attachable to any one of multiple locations on the adjustable leadwire, and a pin that punctures the flexible substrate and electrically connects to the conductor of the adjustable leadwire. The adjustable ECG sensor is fitted to the patient by attaching the clip of the electrode to one of the multiple locations on the adjustable leadwire.
