Nasal Drip Pad With Elastic Ear Loops
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional nasal drip pads used after sinus or nasal reconstructive surgery are cumbersome, uncomfortable, and prone to skin irritation due to adhesives, requiring frequent changes that can lead to infections and discomfort.
Innovation Solution
A nasal drip pad apparatus featuring a drip pad assembly with a cylindrical non-woven fabric roll surrounded by a rectangular gauze pad, secured with an adjustable elastic string that loops around the ears, eliminating the need for adhesives and allowing for easy replacement without skin contact.
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 skin irritation and discomfort occur
Solution Approach 1:
The adhesive is completely removed from the system. Instead of using adhesive to secure the pad, the invention uses an elastic band that loops around the patient's head to hold the pad in place, extracting the harmful adhesive component while maintaining the securing function
Solution Approach 2:
An elastic band is introduced as an intermediary element between the pad and the patient's head. The band serves as a mediator that secures the pad without direct contact with the skin, eliminating the harmful effect of adhesive while maintaining stability
2Reliability
If the gauze pad is changed frequently to maintain sanitation, then infection risk is reduced, but patient discomfort and time loss increase
Solution Approach 1:
The pad, elastic band, and fastening mechanism are merged into a single integrated unit. This allows the entire assembly to be quickly removed and replaced as one piece, reducing the time and complexity of pad changes while maintaining sanitation standards
3Duration of action of stationary object
If adhesive is used to attach the gauze pad, then the pad remains secure during fluid collection, but the adhesive becomes irritating and uncomfortable with prolonged contact
Solution Approach 1:
The adhesive is completely removed from the system. The pad is secured using an elastic band that loops around the head, eliminating direct skin contact with adhesive and allowing for longer wear duration without irritation
Solution Approach 2:
The pad assembly is designed as a disposable unit that can be worn for an extended period and then discarded. This eliminates the need for prolonged adhesive contact while maintaining security and sanitation throughout the wear duration
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 more comfortable, efficient, and sanitary nasal drip pad that reduces the risk of infection by being a single-use, all-in-one disposable dressing with adjustable fit, minimizing skin irritation and adhesive use.

AI summary
A nasal drip pad apparatus for use on a patient after sinus surgery including a drip pad assembly positioned underneath the patient's nose and a string forming a continuous loop configured to extend through the interior of the drip pad assembly configured to form a pair of loops. One of the loops is placed around one of the patient's ears and the other one of the loops is placed around the other one of the patient's ears.
