Heart Failure Treatment Device Differentiating Airway Obstructions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for congestive heart failure patients do not effectively address the range of symptoms and differentiate between obstructive sleep apnea and reflex vocal cord closure, leading to inadequate management and diagnosis of heart failure.
Innovation Solution
A device that detects reflex vocal cord closure and delivers synchronized cardiac waveforms with respiratory treatment pressure to manage symptoms, calculates a heart treatment index, and assesses heart failure through respiratory airflow analysis, distinguishing between types of airway obstructions and providing tailored pressure support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current treatments for congestive heart failure are used, then general symptom management is provided, but differentiation between obstructive sleep apnea and reflex vocal cord closure is not achieved
Solution Approach 1:
The patent segments the diagnosis and treatment process by distinguishing between two distinct conditions: obstructive sleep apnea and reflex vocal cord closure. Each condition is detected and treated separately using specific algorithms and pressure delivery patterns, enabling precise differentiation and targeted therapy rather than generic symptom management.
Solution Approach 2:
The treatment system applies local quality by delivering different pressure support strategies tailored to each specific condition detected. For obstructive sleep apnea, one pressure delivery pattern is used, while for reflex vocal cord closure, a different pattern is applied, ensuring that each condition receives the most appropriate localized treatment approach.
2Reliability
If differentiated diagnosis and tailored pressure support are implemented, then treatment effectiveness is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary action by pre-programming different pressure delivery patterns for different detected conditions. The algorithms are prepared in advance to recognize specific breathing patterns and automatically apply the appropriate treatment protocol, enabling reliable differentiated treatment without requiring complex real-time decision-making during operation.
Solution Approach 2:
The treatment system incorporates feedback mechanisms that continuously monitor breathing patterns and adjust pressure delivery accordingly. The system detects respiratory events, identifies their type, and modifies pressure support in real-time based on the detected condition, creating a closed-loop control system that improves treatment reliability through adaptive response.

AI summary
Methods and apparatus for assessing the condition of and treating patients for heart failure by the delivery of continuous positive airway pressure are disclosed. Treatment of obstruction due to reflex vocal cord closure often experienced by heart failure patients is distinguished from treatment of upper airway obstruction typically associated with Obstructive Sleep Disorder Treatment may also be implemented by delivering synchronized cardiac pressure oscillations superimposed on a respiratory pressure level to provide assistance for the heart. Heart treatment pressure dose indicator may be calculated for prescribing and monitoring the delivery of treatment. The apparatus may also generate data to track heart failure condition that may be indicative of the degree of severity of heart failure based upon breathing patterns to assist in the diagnosis and management of heart failure patients.
