Doctors, 'Techies' Team Up To Make 3D Printed Respirators for Bolivar Hospital

Citizen's Memorial Hospital

What do you get when you mix an infectious disease doctor, a few "techies," and a physician's assistant?  Turns out, it's the winning combination for 3D printed respirators for Citizen’s Memorial Hospital in Bolivar in case the gear is needed in responding to the coronavirus outbreak.

Matt Havens, a physician assistant at CMH, worked with family and tech groups to create respirators through 3D printing. They used a design they found on the web but it didn’t work very well.

Havens said the group went through at least eight designs before the masks passed a “fit test," meaning it seals against the wearer’s face to stop contamination. The test uses sugar substitute in the air; if someone wearing the mask can’t taste it, then it works.

Havens told KSMU he hopes the respirators are never used, calling them a "Plan C" in case the FDA-approved N95 masks run out. But if they are needed, they can be sanitized and reused, and new ones can be printed in 5 hours or less.

Getting more PPE, or Personal Protective Equipment, has been a major goal for hospitals as they prepare for a potential surge in COVID-19 patients.
