Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing respiratory therapy devices and interfaces, such as CPAP masks, suffer from discomfort, poor fit, and reduced compliance due to obtrusiveness, cost, and complexity, leading to inadequate patient adherence to therapy.
Innovation Solution
A patient interface with interchangeable positioning and stabilizing structures, allowing the air circuit to connect superior or inferior to the otobasion superior, and featuring adjustable connection ports and vents, enhances comfort and flexibility, improving fit and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing respiratory therapy devices and interfaces are used, then the therapy can be delivered, but the devices are obtrusive and cause discomfort, leading to reduced patient compliance
Solution Approach 1:
The patient interface is designed with interchangeable positioning and stabilizing structures that can be dynamically adjusted between superior and inferior connection ports relative to the otobasion superior. This dynamic reconfigurability allows the interface to adapt to different patient anatomies and comfort requirements, thereby improving compliance without sacrificing comfort
Solution Approach 2:
The interface is segmented into multiple configurable components including interchangeable positioning structures, adjustable connection ports, and modular stabilizing elements. This segmentation allows individual components to be optimized and reconfigured based on patient-specific needs, reducing obtrusiveness while maintaining therapeutic effectiveness
2Reliability
If existing patient interfaces are used, then the air circuit can be connected, but the interfaces have poor fit and reduced compliance due to obtrusiveness
Solution Approach 1:
The patient interface incorporates universal positioning structures that can function with either superior or inferior connection port configurations. This multi-functionality allows a single interface design to serve multiple connection scenarios, maintaining therapy effectiveness across different anatomical variations without requiring multiple specialized devices
Solution Approach 2:
The interface allows changing of key parameters including connection port location (superior vs. inferior to otobasion superior), positioning structure configuration, and stabilizing element arrangement. These parameter changes enable customization of the interface to achieve optimal fit and comfort while maintaining therapeutic effectiveness
3Productivity
If existing CPAP masks are used, then respiratory therapy can be delivered, but they suffer from discomfort and poor fit leading to inadequate patient adherence
Solution Approach 1:
The interface employs dynamic reconfiguration capabilities with interchangeable positioning structures that can be adjusted between superior and inferior connection configurations. This allows real-time adaptation to patient comfort needs during therapy, thereby improving adherence without compromising comfort
Solution Approach 2:
The interface is designed to be easily reconfigured by the patient themselves through simple interchange of positioning structures and adjustment of connection ports. This self-service capability empowers patients to optimize their own comfort and fit, leading to improved adherence without requiring constant clinical intervention
