Ear-Loop Nasal Drip Pad Eliminates Adhesive Skin Irritation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional nasal drip pads used after sinus or nasal reconstructive surgery are cumbersome, uncomfortable, and pose infection risks due to adhesive use, requiring frequent changes and consisting of multiple parts, which are not sanitary.
Innovation Solution
A nasal drip pad apparatus featuring a drip pad assembly with two distinct layers and a string system that secures around the ears without adhesives, allowing for easy replacement and adjustment, promoting comfort and hygiene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If adhesive is used to secure the gauze pad to the patient's face, then the pad is held in place effectively, but the adhesive causes skin irritation and discomfort to the patient
Solution Approach 1:
The patent removes the adhesive component entirely from the system. Instead of using adhesive to secure the gauze pad, the invention uses a string or band that loops around the patient's head, eliminating the harmful adhesive-skin contact while maintaining effective pad positioning through mechanical tension.
Solution Approach 2:
The patent introduces a string or band as an intermediary element between the gauze pad and the patient's head. This mediator secures the pad in position through looping around the head, replacing the direct adhesive-skin connection with an indirect mechanical fastening system that avoids skin irritation.
2Reliability
If the gauze pad is changed frequently to maintain hygiene, then infection risk is reduced, but the process requires removing adhesive from the patient's cheeks which adds irritation and is time-consuming
Solution Approach 1:
By removing the adhesive component, the patent eliminates the time-consuming and irritating process of adhesive removal during pad changes. The string-based fastening system can be quickly undone and reattached, significantly reducing the time and discomfort associated with frequent pad replacements.
3Reliability
If a single all-in-one disposable dressing is used, then sanitization is improved and infection risk decreased, but the device complexity increases compared to reusable gauze pads
Solution Approach 1:
The patent combines the gauze pad, string, and fastening elements into a single integrated disposable unit. This merging of components creates an all-in-one dressing that maintains hygiene by being disposable while keeping the overall structure relatively simple through functional integration.
Solution Approach 2:
The string or band serves multiple functions: it secures the gauze pad in position, allows for easy adjustment, and can be quickly removed and replaced. This multi-functionality reduces the need for separate components, simplifying the overall device structure while maintaining the benefits of a disposable design.
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 provides a comfortable, efficient, and sanitary nasal drip pad that reduces irritation and infection risk by eliminating adhesive contact and allowing for single-use, easy replacement, enhancing patient comfort and hygiene post-surgery.
Implementation Method 1
