Adhesive Wing Pediatric CPAP Mask for Neonatal Patients
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional CPAP mask headgear is too large and cumbersome for neonatal patients, such as pre-term infants, making it difficult to secure the mask effectively without causing discomfort.
Innovation Solution
A pediatric CPAP mask with adhesive wings that attach directly to the patient's face, eliminating the need for headgear, featuring a central portion surrounding the nose and pairs of wings made from adhesive silicone elastomer, optimized in shape and size for secure adhesion and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional headgear is used to secure the mask, then the mask can be secured to the patient's head, but the headgear is too large and cumbersome for neonatal patients
Solution Approach 1:
The patent removes the headgear component entirely from the mask system, extracting only the essential securing function and implementing it through adhesive material integrated into the mask structure itself. This eliminates the cumbersome headgear while maintaining mask security through direct adhesive attachment to the infant's face.
Solution Approach 2:
The patent combines the mask body and securing mechanism into a single integrated structure by incorporating adhesive material directly into the mask. The adhesive wings are formed as integral parts of the mask, merging the function of attachment with the mask structure itself rather than requiring separate headgear components.
2Reliability
If headgear is used to secure the mask, then the mask can be attached to the patient, but it causes discomfort for pre-term infants
Solution Approach 1:
The patent extracts the harmful headgear component from the system while preserving the essential function of mask attachment. By removing headgear and using only adhesive material integrated into the mask, the solution eliminates the source of discomfort while maintaining secure attachment.
Solution Approach 2:
The patent changes the attachment mechanism from mechanical (headgear straps and buckles) to chemical/adhesive (adhesive material bonding directly to skin). This parameter change in the attachment method eliminates the discomfort caused by headgear while maintaining reliable mask fixation.
3Area of moving object
If a mask is designed for neonatal patients, then it can fit small patients, but traditional headgear cannot be effectively used
Solution Approach 1:
The patent removes the headgear component that cannot be effectively used on neonates, replacing it with an adhesive-based securing mechanism that is scaled appropriately for infant faces and does not require the large headgear structure.
Solution Approach 2:
The patent merges the mask and securing mechanism into an integrated adhesive structure that is appropriately sized for neonates. The adhesive wings are proportioned to fit infant facial contours, combining sealing and attachment functions in a size-appropriate design.
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 adhesive mask provides a reliable and comfortable air seal without headgear, suitable for one-time or reusable use, effectively securing the mask even when the patient lies on their side, addressing the challenge of fitting small pediatric patients.
Implementation Method 1
each wing of the first and second pairs of wings is at least partially provided by an adhesive material
