Solution Overview

Problem

Existing devices for treating upper airway disorders, such as obstructive sleep apnea, often face challenges in patient compliance due to discomfort and inadequate usage, particularly during REM sleep, which can worsen associated conditions like diabetes.

Innovation Solution

A device and method that combine vital sign monitoring, including glucose and norepinephrine levels, with feedback information to patients on their therapy adherence, using statistical data to inform them of predicted versus actual vital sign improvements, thereby enhancing compliance with positive airway pressure (PAP) therapy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If patients use PAP therapy continuously, then health outcomes improve, but patient compliance deteriorates due to discomfort

Engineering Contradiction:
Improvetherapy effectivenessVSAvoidpatient compliance
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system provides real-time feedback to patients about their therapy usage and its direct impact on their glucose levels and health outcomes. This feedback loop motivates patients to maintain compliance by showing them the tangible benefits of continuous therapy usage, thereby resolving the contradiction between therapy effectiveness and patient compliance.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system enables patients to self-monitor their therapy compliance and health outcomes through user-friendly interfaces. Patients can view their own data, understand the relationship between therapy usage and health improvements, and make informed decisions about their treatment, increasing their engagement and compliance without requiring constant medical supervision.

Inventive Principle:
Principle #25Self-service

2Reliability

If PAP therapy is used during REM sleep, then glucose control improves, but patient compliance deteriorates due to mask removal

Engineering Contradiction:
Improveglucose controlVSAvoidtherapy adherence during REM sleep
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system specifically tracks and provides feedback on therapy usage during REM sleep periods and its impact on glucose control. By showing patients the critical importance of maintaining therapy during REM phases for optimal glucose management, the system motivates them to avoid mask removal during these periods, resolving the contradiction between glucose control and adherence.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system provides advance information to patients about the importance of REM sleep therapy for glucose control and prepares them mentally for the critical nature of maintaining therapy during these phases. This preliminary education helps patients understand why they should not remove the mask during REM sleep, improving adherence.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If vital sign monitoring is implemented, then therapy effectiveness improves, but device complexity increases

Engineering Contradiction:
Improvetherapy effectivenessVSAvoidmonitoring system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system integrates multiple functions into a single platform: PAP therapy delivery, vital sign monitoring (including glucose monitoring), data processing, and patient feedback provision. By combining these functions, the system improves therapy effectiveness without requiring separate complex devices for each function, thereby managing overall system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system merges the monitoring of multiple parameters (therapy usage, glucose levels, vital signs, sleep stages) into a unified data processing and feedback system. This consolidation allows comprehensive therapy effectiveness assessment while avoiding the complexity of multiple separate monitoring systems, resolving the contradiction between reliability and device complexity.

Inventive Principle:
Principle #5Merging (Combining)
