Nasal Splint Applicator with Magnetic Fixation and Plunger Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional nasal splints face issues with secure fixation due to either excessive or insufficient magnetic force, and their size is often inadequate for the nasal septum, leading to discomfort and potential injury during insertion.
Innovation Solution
A device comprising a hollow body with a plunger for accommodating and deploying nasal splints in a folded or rolled state, allowing for larger surface area splints to be introduced without size restrictions, using magnets with controlled pressure and an elastic material for secure fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If nasal splints are fixed through sutures or tamponades, then the splints are secured to the nasal septum, but too tight fixation causes pressure necrosis while too slack fixation does not adequately secure the splints
Solution Approach 1:
The patent replaces the mechanical suture/tamponade fixation system with a magnetic field-based fixation system. Magnets embedded in the nasal splints generate magnetic forces that attract to the nasal septum, eliminating the need for physical sutures or tamponades. This substitution allows for controlled magnetic attraction that secures the splints without the excessive localized pressure caused by tight sutures, thereby preventing pressure necrosis while maintaining reliable fixation.
Solution Approach 2:
The patent changes the fixation mechanism from mechanical contact (sutures) to magnetic field interaction. By adjusting magnetic field strength and distribution, the system achieves optimal fixation pressure that is sufficient to secure splints but distributed evenly to avoid pressure necrosis. The magnetic force parameter can be precisely controlled to balance fixation security and tissue protection.
2Reliability
If nasal splints with magnets are used, then the splints are fixed magnetically to the nasal septum, but too strong magnetic forces cause necrosis while too weak forces do not adequately fix the splints
Solution Approach 1:
The patent applies local quality by distributing multiple magnets across the surface of the nasal splint rather than using a single strong magnet. This distribution creates localized magnetic attraction points that collectively provide secure fixation while spreading the magnetic force and pressure over a larger area. The local quality of magnetic interaction at each magnet location prevents excessive concentrated force that could cause necrosis, while the cumulative effect ensures adequate overall fixation.
3Ease of operation
If nasal splints are sized according to nostril dimensions, then they can be introduced into the nose, but the surface area of the splint becomes too small relative to the nasal septum surface area
Solution Approach 1:
The patent applies the nested doll principle by placing the nasal splint inside a hollow body (applicator device) in a compressed or folded state. The hollow body serves as a container that protects and transports the splint without requiring the splint to fit through the nostril in its expanded configuration. During application, the splint is deployed from the hollow body directly onto the nasal septum, allowing the splint surface area to exceed nostril dimensions while maintaining ease of introduction through the compressed state within the applicator.
Solution Approach 2:
The patent resolves the size constraint by changing the dimensional state of the splint during introduction. The splint is compressed or folded into a compact form that fits within the hollow body and can be introduced through the nostril. Once in position, the splint is deployed to its full two-dimensional surface area on the nasal septum. This dimensional transformation allows the final splint size to be independent of nostril size, enabling adequate coverage of the nasal septum surface.

Function Achieved in This Case
Facilitates comfortable and secure fixation of nasal splints with a larger surface area, reducing the risk of injury and pressure necrosis, while allowing for standardization of splint size based on nasal septum dimensions rather than nostril size.
Implementation Method 1
nasal splints with magnets so that two opposite nasal splints applied to the nasal septum attract each other magnetically and become fixed to the nasal septum
Implementation Method 2
a plunger which can be moved in the hollow body, wherein one end face of the hollow body is open so that through a movement of the plunger a nasal splint contained in the hollow body can be introduced from the hollow body through the open end face
