Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for sleep disordered breathing (SDB), such as external breathing therapy devices and surgical interventions, often fail to effectively manage the condition in some patients.
Innovation Solution
The use of an implantable acceleration sensor to identify and track disease burden indicators, such as SDB, by sensing respiratory information and using data models to correlate internally sensed physiologic information with externally sensed data, allowing for the estimation of disease burden without external sensors and simplifying the implantation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external breathing therapy devices and surgical interventions are used to treat sleep disordered breathing, then treatment options are provided, but treatment effectiveness is insufficient for some patients
Solution Approach 1:
The patent implements a closed-loop feedback system where an implantable accelerometer continuously monitors respiratory mechanics (chest wall motion, breathing patterns) and provides real-time data to a control system. The therapy delivery device adjusts therapeutic parameters based on this feedback, enabling adaptive treatment that responds to the patient's actual physiological state, thereby improving treatment effectiveness for refractory SDB cases
Solution Approach 2:
The system transitions from static, fixed-parameter therapy to dynamic, adaptive therapy by continuously adjusting treatment parameters based on real-time respiratory mechanics data. The therapy intensity, timing, and delivery mode are dynamically modified according to the patient's current breathing pattern and respiratory effort, enhancing treatment adaptability and effectiveness
2Measurement precision
If multiple external sensors are used to sense respiratory information, then accurate respiratory data is obtained, but device complexity and implantation difficulty increase
Solution Approach 1:
The patent extracts the respiratory sensing function from external sensors and relocates it to an implantable accelerometer positioned within the patient's body. This single implantable device directly measures respiratory mechanics at the source (chest wall motion), eliminating the need for multiple external sensors and their associated wiring, thereby reducing system complexity while maintaining measurement accuracy
Solution Approach 2:
The implantable accelerometer serves as an intermediary device that bridges the gap between internal respiratory mechanics and external monitoring systems. It captures respiratory information directly from chest wall motion and transmits this data to external systems for analysis, simplifying the overall sensing architecture by replacing multiple external sensors with a single internal sensor
3Loss of information
If multiple external sensors are used for respiratory sensing, then comprehensive data is collected, but implantation process complexity increases
Solution Approach 1:
The patent combines multiple sensing functions (respiratory rate, breathing pattern, chest wall motion) into a single implantable accelerometer device. This consolidation reduces the number of separate implantation procedures needed, simplifying the implantation process while maintaining comprehensive respiratory data collection through the device's multiple sensing capabilities
