N-95 Mask with Integrated Nasal Cannula
For my senior capstone design project, my team sought to create an N95 mask for nasal cannula users in order to protect against airborne pathogens, specifically COVID-19. Over the course of six months, the team created a functional prototype that demonstrates a viable solution for combining N95 filtration with nasal cannula integration to adequately protect the user.
FINAL
The final prototype was tested for fit and comfort, as well as N95 validation. The initial prototype did not pass the Bitrix testing, but with minor adjustments, each of the isolated subsystems passed.
Several improvements were made to the model after initial testing and additional computational analysis was performed to confirm future success of the product.
PLANNING
The group researched key technologies and existing solutions, then conducted informational interviews with field experts and nasal cannula users. This background was used to determine functional requirements for the product, as well factors such as cost and comfort.
Each of the team members presented multiple designs or component concepts, with several of my sketches shown here. The ideas went through a thorough review before the group collaborated on one preliminary design.
MODIFICATIONS
Once the design concept was solidified, I began modeling the mask using the SolidWorks Surfacing Add-On. The supporting hardware was modeled by a teammate, and later modified by myself to improve integration and functionality.
The model of the mask was then used to create a mold negative in SolidWorks, with a parting line in the center for silicone injection. Each of the parts were 3D printed and the mask was assembled along with OTS parts such as foam gaskets and filter material.
Extracurricular
I have always enjoyed visual arts, particularly sketching and drawing. I have recently begun to explore digital art, creating commissioned portraits, business logos, and even a children's book. While this type of creative expression has been a long-standing hobby, I have also found it applicable to the engineering design process.
