Newborn ECG Chest Strip with Segmented Leads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ECG systems are cumbersome and prone to errors when used on newborns, as they are not designed for infants and require skilled operators to untangle cables and place electrodes accurately, leading to challenges in diagnosing conditions like Long QT syndrome, which can be fatal if undiagnosed.
Innovation Solution
A simplified ECG leads system featuring a chest strip with precordial leads, retractable limb leads, and a wireless connector or cable adapter, designed for quick and accurate placement, minimizing skin contact and reducing the risk of errors, compatible with existing ECG machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a regular ECG machine with 10 long cables is used, then complete ECG data can be acquired, but the cables tangle and the process becomes complex and time-consuming
Solution Approach 1:
The patent divides the ECG leads system into modular components: a chest strip with pre-positioned precordial leads and separate limb leads that can be attached as needed. This segmentation reduces cable tangling and simplifies the placement process while maintaining complete ECG data acquisition capability.
Solution Approach 2:
The chest strip is pre-configured with precordial leads in their correct positions before use. This preliminary arrangement eliminates the need for complex cable management during the procedure and reduces placement time, while still allowing complete ECG recording when combined with limb leads.
2Measurement precision
If 10 electrodes are placed manually with cable matching, then accurate ECG signals are obtained, but the process requires skilled operators and takes 20 minutes or more
Solution Approach 1:
The chest strip comes pre-configured with precordial leads positioned correctly before the procedure begins. This eliminates the time-consuming process of manually positioning each lead and matching cables during the procedure, reducing placement time from 20+ minutes to a few minutes while maintaining measurement accuracy.
Solution Approach 2:
The pre-positioned chest strip design allows the system to self-align and self-configure when placed on the patient's chest, eliminating the need for skilled operators to manually position each electrode and match cables. This makes the procedure accessible to non-experts while maintaining diagnostic accuracy.
3Ease of operation
If pre-positioned leads or one-piece design are used, then cable tangling is reduced, but the skin contact area increases which is problematic for newborns with sensitive skin
Solution Approach 1:
The patent separates the precordial leads (on the chest strip) from the limb leads (attached separately). This segmentation allows the chest strip to be smaller and less intrusive on the newborn's skin while still providing complete ECG functionality when combined with the separate limb leads, thus reducing skin contact area and irritation risk.
Solution Approach 2:
The chest strip alone provides partial ECG functionality (precordial leads), which is sufficient for initial assessment. The limb leads can be added only if complete 12-lead ECG is required, allowing the procedure to be completed with minimal skin contact in many cases, thereby reducing skin irritation risk for newborns.
4Object-affected harmful factors
If chest strip designs with 3-6 leads are used, then skin contact is minimized, but limb leads are missing and QT analysis cannot be performed
Solution Approach 1:
The patent divides the ECG system into a chest strip component (providing precordial leads with minimal skin contact) and a separate limb leads component. This segmentation allows the system to maintain low skin contact area while still providing complete 12-lead ECG functionality including all necessary leads for QT interval analysis when both components are used together.
Solution Approach 2:
The combined chest strip and limb leads system provides universal ECG functionality, enabling both minimal skin contact operation (using chest strip alone for preliminary assessment) and complete 12-lead ECG analysis (when limb leads are added), thus adapting to different clinical needs while maintaining QT analysis capability.
