GREENVILLE, S.C. (WSPA) – An innovative ventilator device has been developed by Prisma Health to assist more patients at one time.
The FDA gave emergency use authorization of a “Y” splitter tubing to allow a single ventilator to assist up to four patients.
Prisma Health experts are working with national COVID-19 teams who have no more ventilator capacity and who can initiate emergency use of the prototype. They will be working closely with these teams during their field testing to monitor clinical outcomes. Those field tests will determine whether the device performs as designed, per FDA guidelines.
Emergency use authorization can offer critical care patients access to a medical device that has not gone through normal FDA approval; this is used when no comparable or satisfactory alternative options are available.
“When we see rapid increases in patients who require machine-assisted breathing, an acute shortage of necessary equipment can happen overnight,” said Peter Tilkemeier, M.D., chair of the Department of Medicine at Prisma Health-Upstate. “The VESper™ device can be lifesaving when the number of critically ill patients requiring breathing support is greater than the number of available ventilators. A number of U.S. hospitals are likely to begin experiencing this with COVID-19.”
A Prisma Health emergency medicine physician realized the opportunity of using a single machine to breathe for multiple patients.
Working collaboratively with her husband, a software engineer and with a Prisma Health pulmonary critical care physician, this team began developing specifications for a “Y” splitter tubing that would meet international quality standards (ISO), be easily produced, allow for appropriate filtering of bacteria and viruses in the ventilator tubing, be strong and impact resistant, and would not impact the care of other patients connected to the same machine.
“Immediately, we realized we had an opportunity to impact patient outcomes all over the country, and potentially beyond the U.S.,” said Marjorie Jenkins, M.D., chief academic officer for Prisma Health–Upstate and dean of the University of South Carolina School of Medicine Greenville. “What we needed was a collaborative team to put the plan in motion and close the loop between design, production, FDA approval and distribution to hospitals with critical need.”
Drawing on the strength of Prisma Health’s existing academic partnerships, specifications were sent to engineers at Clemson University and University of South Carolina for 3D materials testing and printing of prototypes. The team began working to secure FDA approval and collaborations with private sector businesses came together within a matter of days.
Physicians used Prisma Health’s Healthcare Simulation Center to begin testing the VESper™ device with medical manikins, allowing for the simulation of multiple clinical scenarios. The device was able to deliver the appropriate breathing parameters without difficulty, creating an opportunity to pursue an application for emergency use authorization with the FDA to rapidly bring this life-saving device directly into clinical use.
Hospitals can begin to apply to receive the free source code and printing specifications for the device today by registering on Prisma Health’s Website www.prismahealth.org/VESper for their use in printing the VESper™ device.
Prisma Health is collaborating with other major companies such as HP Inc. and its Digital Manufacturing Network to quickly scale 3D production of validated parts for distribution in areas of greatest need and areas with the potential to exceed their ventilator capacity in the near future, such as COVID-19 “hot spots” as designated by the Federal Emergency Management Agency (FEMA). Currently Prisma Health and South Carolina hospitals have enough ventilators available for patients.
“This is an exemplary demonstration of rapid innovation and collaboration,” said Mark O’Halla, president and chief executive officer of Prisma Health. “I am so proud of the creativity and perseverance of our clinical team who came together to develop a potentially life-saving solution at a critical time for our country, our communities and our patients. We are anxiously awaiting the results of the prototype field tests.”
