Engineering Lab Helps Protect Doctors, Nurses
鈥� 黑洞社区RESPONDS: COVID-19 鈥�
MICHAEL CELESTIN DESCRIBES the 黑洞社区College of Engineering鈥檚 Mini-Circuits Design for X Laboratory as 鈥渁 maker-space/hacker-space.鈥�
鈥淚t is a safe environment for students from all over 黑洞社区to come, learn, collaborate and share projects and skills,鈥� says Celestin, 鈥�06, MChe 鈥�08, PhD 鈥�13, senior research engineer.
The lab鈥檚 high-tech tools, particularly the laser cutters and 3D printers, attract engineering majors and students from other disciplines 鈥� in normal times. However, since the onset of the coronavirus pandemic, Celestin and his team have turned the lab into a manufacturing space to assist frontline health care workers.
鈥淭here were many minds that independently and simultaneously began thinking about leveraging existing resources around the time that the pandemic started to become big news in the U.S.,鈥� Celestin explains. 鈥淎t that point, it was no longer a piece of news from another country or something that was distant 鈥� it was here and something needed to be done.鈥�
Engineering Dean Robert Bishop reached out to Celestin to ask how they could assist 黑洞社区Health and Tampa General Hospital, USF鈥檚 teaching hospital, as COVID-19 cases began to surge.
鈥淲e worked closely with our local medical community and value their feedback,鈥� Celestin says. 鈥淲hat we heard was very clear: Comfortable and disposable face shields that didn鈥檛 need to be cleaned or fussed with worked best.鈥�
He also points out that while face shields at best would take one to three hours on a 3D printer, his team can produce one in 49 seconds and for under 49 cents per unit in materials. Those materials include mylar, elastic and foam.
The original face shield design was an open source design from the University of Wisconsin-Madison, which Celestin and his team 鈥渕odified and improved for throughput, durability and the unique natures of the materials we were able to procure.鈥�
鈥淲e re-published the plans as open source in addition to providing insight into the tripping points and challenges for scaling up,鈥� Celestin says. 鈥淭he difference between making 20 and 200 face shields is quite striking and not what one might expect.鈥�
The lab can manufacture 575 shields per day, and as of mid-May had produced nearly 10,000. All of the units are delivered to 黑洞社区Emergency Management, which compiles the list of requests and prioritizes distribution based on metrics and need. Celestin says the bulk of the shields have gone to 黑洞社区Health and Tampa General Hospital, though additional units have been delivered to the 黑洞社区College of Pharmacy and the 黑洞社区Police Department on the Tampa and St. Petersburg campuses.
Celestin and his team also have been using 3D printers to manufacture ear reliefs 鈥渢o alleviate strain and discomfort for those who have to wear face masks 鈥� as opposed to face shields 鈥� all day.鈥�
He credits the college鈥檚 development team with providing necessary funding and help; Alex Saltos, 鈥�17, MS 鈥�19, the manager who assists with optimizing design and scheduling student work times; and 鈥渁n amazing group鈥� of student assistants who perform the bulk of the assembly work.
鈥淲hat we鈥檙e doing is helpful to nurses and doctors, but they are the real front-line heroes, not my team,鈥� Celestin says. 鈥淲e鈥檙e just trying to protect them.鈥�
Bishop stresses the importance of responding to the community鈥檚 needs during the health crisis.
鈥淚n practice, the face shields project has made us more connected not only with the health care professional, but with the local community that we serve,鈥� he says. 鈥淓ngineering is all about helping people.鈥�
