ÐÓ°ÉÔ­°æ

Shortly after the University of New Haven announced that ÐÓ°ÉÔ­°æ“ amid the coronavirus global pandemic ÐÓ°ÉÔ­°æ“ all classes would be conducted remotely for the remainder of the spring semester, Anthony Iovene ÐÓ°ÉÔ­°æ™21 M.S. was approached by his adviser to work on designing some t-connectors and adapters ÐÓ°ÉÔ­°æ“ components of medical ventilation systems ÐÓ°ÉÔ­°æ“ that could be created using a 3D printer.

Using dimensions he found online and parameters provided by Kagya Amoako, Ph.D., associate professor of biomedical engineering, Iovene got to work, using the computer program SolidWorks to design the parts.

"This is a global emergency and pandemic, and, as a biomedical engineer, I feel it is our duty to do everything we can to help," said Iovene, a candidate in the UniversityÐÓ°ÉÔ­°æ™s graduate program in biomedical engineering. "It is our hope that we will be able to donate these parts to medical facilities in need."

While responding to the coronavirus pandemic, healthcare providers around the world have, at times, been unable to obtain the necessary medical supplies and equipment. Dr. Amoako, coordinator of the UniversityÐÓ°ÉÔ­°æ™s graduate program in biomedical engineering, believes 3D printing is an innovative way to help address that need.

"Based on the trajectory of the number of confirmed cases of COVID-19 and fatality rates in the U.S., it is not unrealistic to think that we may face similar experiences of not having enough ventilators to provide respiratory support for the sick," said Dr. Amoako, who serves as director of the UniversityÐÓ°ÉÔ­°æ™s . "This is currently happening in Italy and Spain, and it could happen here."

Medical ventilators are used to provide respiratory support to critically ill patients who are unable to breathe on their own. Typically, breathing machines bring oxygen through a single tube to a patientÐÓ°ÉÔ­°æ™s lungs. Another single tube will then take expired gases away from the lungs.

Dr. Amoako and his students have developed 3D printed flow connectors that would enable physicians to treat two severely ill COVID-19 patients using one ventilator. With the connector, the two lines can be bifurcated so that two patients can be hooked up to a single breathing machine.

Dr. Amoako says this method has been used in the past when mechanical ventilators were scarce, such as when treating patients who were hurt in a mass shooting at a music festival Las Vegas in 2017.

Even though faculty, staff, and students at the University are currently working and learning remotely, Dr. Amoako says there are still many ways to collaborate and innovate.

"We developed these flow connectors over a couple of days while working remotely," he explains. "We are willing to donate these important pieces to critical care units that need them to augment their COVID-19 case surge and to support their critical-care support strategies."

Help University of New Haven Students Charge Ahead

We've launched the Charge Ahead Student Support Fund in an effort to raise financial assistance for our students for such necessities as remote learning technology, food, housing, medical expenses, and other emergency needs. Please to make a contribution that will assist those in our University community who need our support.
