Mission:
Create a device that protects individuals with high-level spinal cord injuries from COVID-19 transmission while allowing full use of assistive technologies like mouth sticks and sip-and-puff controls.

Design Rationale:
The Flap Mask consists of an acrylic inner frame and a separate flap mechanism. The oval-shaped acrylic inner frame, thermoformed to fit the user's face, features a rectangular center cutout and four side cutouts, providing a snug fit and enhanced breathability.
The flap mechanism consists of two layers of silicone flaps. The top layer has six rectangles, while the bottom layer has two. These flaps cover the user's mouth, ensuring COVID-19 protection. The silicone material allows easy insertion of mouth sticks and sip-and-puff controls while maintaining a secure seal.
When assistive technologies are not in use, the flaps close the mask shut. The washable flap mask insert can be added into any N95 mask for added protection.
Problem:
The COVID-19 pandemic has exacerbated challenges for people with quadriplegia. Wearing a mask hinders the effective use of mouth sticks and sip-and-puff controls, forcing individuals to choose between protection and accessibility. Existing solutions like cloth zipper masks fall short in providing sufficient in-person protection during mentor sessions.
Users and Requirements:
The primary user is an adult with a high-level spinal cord injury (C3/C4 level), relying heavily on a mouth stick and sip-and-puff controls. The mask should offer COVID-19 protection while facilitating the independent and easy use of these assistive technologies. Durability for up to 12 hours of continuous wear is essential.
