Textile Air Delivery Conduit for Stable PAP Mask Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air delivery conduits for Positive Airway Pressure (PAP) systems are often uncomfortable, obtrusive, and can disrupt the seal of facial masks, leading to reduced compliance and ineffective treatment of Sleep Disordered Breathing conditions like Obstructive Sleep Apnea.
Innovation Solution
The development of an air delivery conduit made from a textile material with specific elastic properties in different directions, incorporating a reinforcing structure and a smooth inner surface, which reduces torque and drag, maintaining a stable mask seal and enhancing user compliance through reduced intrusiveness and visual appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional air delivery conduits are used, then the structure is simple and easy to manufacture, but the conduit is obtrusive and can disrupt the mask seal
Solution Approach 1:
The air delivery conduit uses a composite structure combining a textile outer layer with an inner tubular member. The textile provides flexibility and comfort while the inner member maintains structural integrity and airtightness, resolving the contradiction between simplicity and performance.
Solution Approach 2:
The conduit employs a flexible textile outer layer that can conform to patient movements without disrupting the mask seal, while the inner tubular member provides the necessary structural support to maintain the airway pressure.
2Ease of operation
If the conduit is made from textile material, then comfort and visual appeal are improved, but airtightness becomes more difficult to achieve
Solution Approach 1:
The textile outer layer is combined with an inner tubular member that provides the airtight barrier. This composite approach allows the conduit to benefit from the comfort and aesthetics of textile while ensuring reliable airtightness through the specialized inner member.
Solution Approach 2:
The inner tubular member acts as an intermediary between the textile outer layer and the breathable gas flow, providing the necessary airtight seal while allowing the textile to provide comfort and aesthetic functions.
3Ease of operation
If the conduit lacks reinforcing structure, then it is more flexible and comfortable, but crush resistance is reduced
Solution Approach 1:
The conduit combines a flexible textile outer layer with an inner tubular member that provides structural reinforcement. This composite structure maintains flexibility for comfort while providing adequate crush resistance through the reinforced inner member.
Solution Approach 2:
The reinforcing structure is strategically positioned within the conduit to provide crush resistance only where needed, while allowing the rest of the conduit to remain flexible for comfort during patient movement.
4Ease of operation
If the conduit material has high elasticity, then comfort is improved, but torque and drag increase
Solution Approach 1:
The textile outer layer provides high elasticity for comfort during patient movement, while the inner tubular member with reinforcing structure counteracts the torque and drag forces, preventing excessive twisting and maintaining stable gas delivery.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The textile air delivery conduit provides increased comfort, reduces conduit drag, and enhances treatment effectiveness by maintaining a stable mask seal, potentially eliminating the need for additional swivel components and improving patient compliance due to its lightweight and supple nature.
Implementation Method 1
a textile that has a first elasticity in a first direction and a second elasticity in a second direction
