Repositionable Electrode System for Cardiotherapy Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Adhesive electrodes used in cardioversion for treating atrial fibrillation are difficult to reposition properly, which is crucial for the success of the treatment, as improper positioning can lead to ineffective cardioversion and increased risk of stroke.
Innovation Solution
A repositionable electrode system with varying adhesive strengths and a conductive release layer allows for easy repositioning and secure adherence, coupled with an electrocardiotherapy device that analyzes signal quality to identify the optimal placement location on a patient's body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive electrodes are used for cardioversion, then the electrodes can be securely attached to the patient's chest, but they cannot be readily repositioned to a better location if the initial location proves inadequate
Solution Approach 1:
The electrode is divided into multiple segments with different adhesive strengths. The first portion has high adhesive strength for secure attachment, while the second portion has low adhesive strength for easy repositioning. This segmentation allows the electrode to be initially secured reliably but then easily moved to optimize positioning for cardioversion.
Solution Approach 2:
Different portions of the electrode have different adhesive properties. The first portion is designed with high adhesive strength to ensure secure attachment during initial placement, while the second portion has reduced adhesive strength to facilitate repositioning when needed. This local differentiation resolves the contradiction between secure attachment and repositionability.
2Reliability
If proper electrode positioning is emphasized for successful atrial defibrillation, then treatment effectiveness improves, but the complexity of ensuring correct placement increases
Solution Approach 1:
The system provides real-time feedback to the healthcare professional during electrode placement. The electrocardiotherapy device analyzes the ECG signal quality and provides visual or auditory indicators to guide proper electrode positioning. This feedback mechanism simplifies the positioning process by automatically guiding the professional to the correct location without requiring complex manual measurement or trial-and-error approaches.
3Productivity
If adhesive electrodes are adhered to the patient's chest for cardioversion, then the treatment can proceed, but any initial inadequate positioning cannot be corrected without removing and reapplying the electrode
Solution Approach 1:
The electrode transitions from a static, fixed adhesive state to a dynamic, repositionable state. The low-adhesive second portion allows the electrode to be easily removed and repositioned without requiring complete removal and reapplication, enabling rapid adjustment to optimize positioning for cardioversion treatment.
