Releasable Liner for ECG Sensor Electrodes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional protective liners for electrocardiogram (ECG) devices are cumbersome and difficult to apply, complicating the attachment of electrode vests to patients and potentially causing electrodes to stick to the wrong locations or other parts of the vest.
Innovation Solution
A releasable protective liner system with a first strip portion attached to the sensor device and a second strip portion that can be pulled to separate from the electrodes, allowing controlled and systematic removal, enabling easy application of the vest and electrodes to the patient.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single protective sheet covers all electrodes on a vest, then the protective coverage is comprehensive, but the removal process becomes complex and time-consuming
Solution Approach 1:
The protective liner is divided into multiple independent electrode covers, each covering a specific electrode area. This segmentation allows each electrode to be covered independently while enabling systematic removal by pulling the free end of each cover, transforming a complex single-sheet removal into simple individual actions.
2Reliability
If individual protective patches are used for each electrode, then each electrode is protected, but the application and removal process becomes time-consuming and cumbersome
Solution Approach 1:
Multiple individual electrode covers are merged into a single integrated protective liner that can be applied and removed as one unit. The liner includes multiple electrode covers connected together, allowing comprehensive protection while enabling rapid removal by pulling the free end of the entire liner, thus reducing time loss.
3Object-affected harmful factors
If conventional protective liners are used, then electrodes are protected from the environment, but the liners are unwieldy and difficult to apply
Solution Approach 1:
The protective liner is designed with a dynamic structure where electrode covers can be systematically removed from a fixed end to a free end. This dynamic removal mechanism, combined with the liner's flexible material properties, enables easy application and removal while maintaining protective function, transforming a static cumbersome liner into a dynamically manageable component.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution simplifies the application process by allowing for quick and controlled exposure of electrodes to the patient's skin, preventing misplacement and ensuring proper adhesion, while maintaining the integrity of adhesive patches and conductive gel until needed.
Implementation Method 1
The electrodes may also have an adhesive section to allow the electrodes to stay connected to the patient's skin during an ECG test. In addition, or alternatively, the conductive gel may have adhesive properties to allow the electrodes to adhere to the patient.
Implementation Method 2
The gel better enables signal transfer between the patient's body and the electrode.

AI summary
A releasable liner for a sensor device having adhesive and conductive gel portions includes a flexible sheet having a free end and a fixed end, and a portion of the flexible sheet that is releasably attached to the sensor device, wherein the flexible sheet is folded upon itself so that the fixed end is generally adjacent the free end. Exerting a pulling force on the free end releases the liner in a controlled manner to uncover the adhesive and conductive gel portions of the sensor device.
