CPAP Mask Access Portion with Compliant Membrane
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional respiratory interfaces for sleep apnea treatment, such as CPAP masks, are uncomfortable to wear, preventing users from accessing irritated areas of the face without waking up, leading to disrupted sleep and potential non-use of the device.
Innovation Solution
Incorporating access portions with a compliant surface, such as a flexible or elastic membrane, allowing users to reach irritated areas like the nose, lips, or cheeks without removing the mask, which are sized to accommodate a finger and can include abrasive elements for improved scratching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealed respiratory interface is used to treat sleep apnea, then the treatment effectiveness is improved, but the user cannot access irritated areas of the face without waking up
Solution Approach 1:
The respiratory interface is divided into a main sealed mask body and separate access portions. Each access portion is an independent component that can be actuated independently, allowing users to access specific irritated areas without compromising the overall seal of the respiratory interface.
Solution Approach 2:
A membrane is introduced as an intermediary element between the access portion and the user's face. This membrane allows tactile feedback to be transmitted while maintaining the sealed environment, enabling users to feel and access irritated areas without breaking the seal.
2Reliability
If the mask seal is tightened to improve treatment effectiveness, then sleep apnea treatment is enhanced, but user comfort deteriorates and access to face areas becomes more difficult
Solution Approach 1:
The interface is segmented into the main seal portion and detachable access portions. This allows the main seal to be tightened for effective treatment while the access portions remain independently operable, preventing the need to loosen the seal for comfort needs.
Solution Approach 2:
The access portions are designed with dynamic characteristics, including spring mechanisms and flexible membranes, allowing them to move and adapt during use. This dynamic design enables users to access irritated areas without affecting the static, tightened seal of the main mask.
3Ease of operation
If access portions are added to allow finger access, then ease of operation is improved, but device complexity increases
Solution Approach 1:
Flexible membranes are used in the access portions to provide a simple yet effective mechanism for finger access. These thin film structures allow tactile interaction without requiring complex mechanical assemblies, minimizing the increase in device complexity.
Solution Approach 2:
The access portions are designed to be self-actuating through simple mechanical means such as spring mechanisms that automatically return to their original position. This self-service capability reduces the need for complex control systems or additional actuation mechanisms.
