Nosebleed-Attenuating Apparatus Pressure Applicator Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods are inadequate in effectively addressing nosebleeds, as they fail to efficiently reduce the severity of bleeding from the nose, particularly in areas like Kiesselbach's plexus where most nosebleeds occur.
Innovation Solution
A nosebleed-attenuating apparatus featuring a pressure applicator that engages with the external bodily surface near the nasal vascularization area between the nose and upper lip, coupled with a pressure receiver to apply sufficient pressure to constrict blood flow to the septal branch of the superior labial artery, thereby reducing bleeding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional nosebleed treatment methods are used, then the treatment process is simple, but they fail to effectively reduce bleeding severity
Solution Approach 1:
The device is divided into distinct functional components: a pressure applicator component that contacts the nasal vestibule, a pressure receiver component that receives manual pressure input, and a coupling mechanism that transfers the pressure. This segmentation allows each component to be optimized for its specific function while maintaining overall simplicity.
Solution Approach 2:
The pressure applicator acts as an intermediary between the user's manual pressure and the nasal vascularization area. Instead of directly pressing on the sensitive nasal area, the device provides a controlled interface that distributes pressure evenly and effectively targets the bleeding site through the coupling mechanism.
2Reliability
If pressure is applied directly to the nasal area, then bleeding can be reduced, but it causes discomfort and requires precise positioning
Solution Approach 1:
The pressure applicator is designed with a surface area and geometry that can effectively treat nosebleeds regardless of the specific location or cause (anterior vs. posterior, left vs. right). The coupling mechanism between the pressure applicator and receiver ensures that pressure is effectively transmitted to target the septal branch of the superior labial artery in various nasal vascularization patterns.
Solution Approach 2:
The device distributes pressure across a two-dimensional surface area of the pressure applicator rather than concentrating it at a single point. This dimensional approach allows the force from manual pressure on the pressure receiver to be effectively distributed across the nasal vestibule, achieving reliable blood flow constriction without requiring precise point-to-point positioning.

Function Achieved in This Case
The apparatus effectively attenuates nosebleeds by reducing blood flow to Kiesselbach's plexus, providing rapid relief within less than 60 seconds and alleviating symptoms of epistaxis.
Implementation Method 1
a pressure receiver coupled to the pressure applicator, the pressure receiver configured to receive pressure; whereby an amount of the pressure is transferred to the pressure applicator for application to the external bodily surface
