Medical Electrode Finger Grip for Single-Handed Liner Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical electrodes require the use of both hands to remove the protective liner, leading to potential incorrect positioning due to the need to look away from the application spot and increased risk of touching the adhesive layer or contact medium.
Innovation Solution
A medical electrode with a finger grip arranged at the top side of the disc, allowing a clinician to hold the electrode with one hand and remove the protective liner using the same hand, thereby maintaining correct positioning and minimizing contact with adhesive areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the protective liner is removed using both hands (one hand to hold the electrode, one hand to peel the liner), then the liner can be effectively removed, but the positioning accuracy deteriorates because the clinician must look away from the application spot
Solution Approach 1:
The finger grip structure combines the functions of holding the electrode and removing the protective liner into a single integrated component. The U-shaped finger grip allows the clinician to perform both actions (holding and peeling) with one hand, eliminating the need to switch hands or look away from the application spot, thus maintaining positioning accuracy while ensuring effective liner removal.
2Ease of operation
If the protective liner is removed using both hands, then the liner can be effectively removed, but the risk of touching the adhesive layer or contact medium increases
Solution Approach 1:
The finger grip acts as an intermediary tool between the clinician's hand and the electrode. By gripping the electrode through the U-shaped finger grip structure, the clinician's fingers are positioned away from the adhesive layer and contact medium areas, preventing direct contact and potential contamination while still enabling effective liner removal.
3Measurement precision
If a finger grip is added to the electrode, then single-handed operation is enabled and positioning accuracy is maintained, but the device complexity increases
Solution Approach 1:
The finger grip structure serves multiple functions simultaneously: it provides a gripping surface for single-handed handling, acts as a lever arm for effective liner removal, and positions the clinician's fingers away from contamination areas. This multi-functionality justifies the added structural element by delivering multiple benefits from a single design feature.

AI summary
The medical electrode (1) includes a disc (2) having a top side (3) and a bottom side (4), an electric connector (11), a contact medium being arranged at the bottom side of the disc and being electrically connected to the electric connector, a layer of pressure-sensitive adhesive being applied to at least a part of the bottom side of the disc, and a protective liner (12) being adhered to the bottom side of the disc by means of the pressure- sensitive adhesive. A finger grip (14') is arranged at the top side of the disc, and the finger grip forms a finger insert opening (20) into which a fingertip may be inserted and thereby hold the medical electrode during handling.
