UW engineers, local manufacturers work to produce medical face shields
University of Wisconsin-Madison engineers are working with Madison-area manufacturers on medical face shields for healthcare workers treating coronavirus patients.
A first batch of face shields has been created for UW Hospital, with plans to deliver samples to other local hospitals for feedback. The group also has published its design as open source — which can be seen
— and it is already be replicated by others across the world.
The medical face shields, which are key pieces of personal protective equipment (PPE), come from a design consulting firm Delve, and campus colleagues, according to a release on Monday.
The group has built prototypes and launched a
where it’s encouraging healthcare facilities, manufacturers and donors to fill out an intake form to help assess need and build more connections while production capacity is rapidly expanded.
“This is just one piece of the equation,” Lennon Rodgers, director of the Grainger Engineering Design Innovation Lab, the makerspace on the UW–Madison College of Engineering campus, says. “Hospitals need N95 masks and other critical equipment. Our aim is to provide the shields at cost — and maybe free if donors step forward. We’d like to get 100,000-plus packed up and shipped from Madison to hospitals in need ASAP.”
The group created a design based closely on the face shields currently in use at UW Hospital, consulting throughout with Robert Scheuer, director of materials management at UW Health, to ensure the product is medical-grade quality, according to the release.
"Mass production isn’t a problem," according to the release.
Local manufacturer Placon and Plastic Ingenuity estimates it can churn out 5,000 plastic shields an hour, and Rodgers says assembly time to create the finished product, which entails adding an adhesive-backed foam strip and a latex-free elastic headband, takes less than 30 seconds for each unit.
The team is still trying to gauge demand across the country and even beyond, and connect with specific healthcare facilities that are interested in ordering shipments of face shields, according to the release.
Rodgers notes that other facilities, such as prisons and nursing homes, could also benefit from having shields as the virus continues to spread.
“We could almost certainly ship millions of face shields over time if we can put together the final pieces of manufacturing and distribution. Equally critical is continually identifying the hospitals that need the face shields.” Rodgers said.
