Nasal Breathing Device with Support Rings for Stable Ventilation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing headband-style respiratory masks used with ventilators are inconvenient and uncomfortable for patients, particularly those with head injuries or claustrophobia, and fail to provide stable fixation during ventilation, leading to potential mask displacement and discomfort, especially during sleep.
Innovation Solution
A nasal breathing and ventilation device featuring a nasal brace with sequentially arranged support rings that snugly fit the nasal cavity, ensuring stability and comfort without a headband, combined with a ventilation tube for effective airflow and gas exchange, and optionally using two tubes with connecting structures for enhanced fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If headband-style respiratory masks are used, then ventilation function is provided, but patient comfort and stability are compromised due to head injuries or claustrophobia
Solution Approach 1:
The invention extracts the headband component from the respiratory mask system, removing the source of discomfort and injury risk while preserving the essential ventilation function through nasal cannulae that insert directly into the nasal cavity without requiring headband fixation
Solution Approach 2:
The nasal cannulae are designed as disposable components that can be easily replaced, ensuring hygiene and comfort for patients who cannot tolerate headband-style masks, while maintaining reliable ventilation delivery
2Reliability
If headband-style respiratory masks are used, then ventilation is provided, but fixation stability deteriorates causing mask displacement
Solution Approach 1:
The headband fixation mechanism is removed entirely, replacing it with direct nasal cavity insertion of cannulae that achieve stable positioning through anatomical fit rather than external headband compression
Solution Approach 2:
The nasal cannulae act as intermediaries that deliver ventilation directly to the nasal cavity, eliminating the need for headband mediation and achieving stable fixation through the natural contours of the nasal passage
3Ease of operation
If nasal cannulae are used without headband, then patient comfort is improved, but fixation stability worsens causing device to fall off
Solution Approach 1:
The nasal cannulae are designed with specific local qualities including curved shapes that follow nasal cavity contours and flared distal ends that engage with nasal anatomy, providing adequate fixation stability without requiring headband-style external support
Solution Approach 2:
The nasal cannulae incorporate curved geometries that adapt to the natural shape of the nasal passage, with bent sections and flared ends that provide mechanical engagement and prevent displacement while maintaining patient comfort

AI summary
A nasal breathing and ventilation device, includes ventilation tubes. One end of each ventilation tube is provided with a nasal dilator. Each nasal dilator includes a nasal dilator channel and a plurality of dilator rings. One end of each nasal dilator channel is provided with a through hole. Each nasal dilator is supported and fixed in the nasal cavity by means of the dilator rings thereof, and is not easy to fall out. The end of each nasal dilator channel away from the through hole is in communication with each ventilation tube. The tube wall at the end of each ventilation tube close to the nasal dilator is provided with ventilation holes. The end of each ventilation tube away from the nasal dilator is connected to a ventilator, and the ventilator conveys air into the nasal cavity at a certain pressure.
