Oral Flow Therapy System for Reducing Breathing Work
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current respiratory therapy systems for conditions like Obstructive Sleep Apnea, Cheyne-Stokes Respiration, and Chronic Obstructive Pulmonary Disease face challenges in effectively managing upper airway obstruction and dead space, leading to inadequate ventilation and increased work of breathing due to the need for invasive and uncomfortable patient interfaces, as well as the complexity and cost of titration processes.
Innovation Solution
A method and apparatus providing oral flow therapy with a sealed oral interface that delivers a constant flow of pressurized breathable gas to reduce nasal and oral dead space, using a controller to synchronize gas delivery with the respiratory cycle and adjust pressure to prevent obstruction, thereby reducing the work of breathing and improving ventilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional respiratory therapy systems are used to manage upper airway obstruction and dead space, then ventilation support is provided, but the patient interface becomes invasive and uncomfortable
Solution Approach 1:
The patent inverts the traditional approach by delivering therapy through the mouth rather than the nose. The mouthpiece interface is less invasive and more comfortable than traditional nasal masks, while still providing effective positive pressure ventilation support to manage upper airway obstruction and dead space.
Solution Approach 2:
The patent extracts the therapy delivery from the traditional nasal mask interface and relocates it to a simple mouthpiece. This extraction eliminates the need for complex sealing around the nose and face, reducing invasiveness while maintaining ventilation support effectiveness.
2Reliability
If titration processes are used to adjust therapy parameters, then optimal ventilation is achieved, but the process becomes complex and costly
Solution Approach 1:
The system incorporates automatic titration capabilities that adjust therapy parameters based on real-time monitoring of patient breathing patterns. This self-adjusting mechanism eliminates the need for complex manual titration processes, reducing both device complexity and operational costs while maintaining optimal ventilation.
Solution Approach 2:
The patent implements feedback mechanisms that continuously monitor respiratory parameters and automatically adjust therapy delivery. This closed-loop control system simplifies the titration process by using real-time data to optimize ventilation parameters without requiring complex manual intervention.

AI summary
A therapy system configured to wash out or flush out the oral and/or nasal cavity to reduce the effective dead space and reduce the work of breathing. The system may displace the expired air in the oral and/or nasal cavity with atmospheric air, or air with altered concentrations, for example, increased humidity, or oxygen levels. A sealed oral interface is provided to the mouth of a patient to supply a volume of pressurized gas. A control system to synchronize the supply of pressurized gas with the patients respiratory cycle. The supply of respiratory gas may be provided during only a portion of the respiratory cycle.
