Biomedical engineering graduates from the 国产短视频 are receiving national accolades for a prototype device that may help solve the critical shortage of lifesaving ventilators seen around the world throughout the COVID-19 pandemic.
The Eucovent, a patent-pending device that allows two patients to be ventilated by a single machine, was developed by 国产短视频students Carolyna Yamamoto Alves Pinto, Abby Blocker and Jacob Yarinsky. The trio built the device as part of their biomedical engineering degree senior design project.
鈥淚 think what stood out most was how relevant a topic ventilation was at the time, and still is today,鈥� Yarinsky said. 鈥淓specially with what you saw happening around the world with COVID-19 and hospitals not having enough ventilators for the numbers of patients they were treating. The project seemed extremely relevant and meaningful.鈥�
That idea was submitted to the class by Moffitt Cancer Center researchers Aaron Muncey, Heiko Enderling and Stefano Pasetto, who were looking for novel solutions to problems with co-ventilation. While there are existing devices capable of 鈥渟plitting鈥� airflow to multiple patients, most available solutions do not offer any type of customization. This is particularly problematic as patients require different volumes of airflow depending on their lung compliance and body weight, among other factors. For example, a 150-pound woman might require substantially less airflow than a 250-pound man.
To solve this, the team employed two primary techniques: dynamic resistance and time multiplexing. Dynamic resistance refers to an obstruction that restricts the amount of air delivered to each patient. To accomplish this, the group fabricated custom valves that can be independently adjusted to meet each patient鈥檚 individual airflow needs. By using time multiplexing, a common digital signals technique suggested to the team by 国产短视频Professor Christopher Passaglia, the device can alternate between patients, efficiently delivering breaths to each person independently.
Along with these two primary solutions, the team members had to utilize all of their undergraduate research experience for the project. Using their knowledge of biomechanics, along with such methods as 3D printing, computer programming and modeling, as well as computer-aided design, the group was able to complete and test the prototype with much success.
鈥淚t was a great joy and privilege to work with Abby, Jacob and Carolyna, each talented in their own right with unique and complementary skillsets and see them transform an initial seed idea into innovative new technology,鈥� said , assistant member of Moffitt鈥檚 Department of Anesthesiology. 鈥淭heir commitment, dedication and work ethic were essential to bringing this project to fruition and I expect that we will impact the lives of many patients with further development of this technology.鈥�
The relevance of such a device became clear during the COVID-19 pandemic, as hospitals around the world struggled to provide ventilators to every patient who needed one. The Eucovent effectively doubles a hospital鈥檚 existing capacity without having to purchase additional ventilators, which can cost upwards of $15,000 per unit. The team says its use reaches far beyond the current pandemic, with applications in natural disaster settings, remote locations and low-resource areas.
鈥淲e believe the Eucovent provides many benefits, including cost and safety,鈥� Yamamoto Alves Pinto said. 鈥淐ompared to a new ventilator, the device is extremely low-cost, making ventilation more accessible and affordable. It also offers a higher level of patient care compared to existing solutions, making it a safer and more reliable option for co-ventilation.鈥�
鈥淭his project shows the opportunity that we have for joint research endeavors between Moffitt Cancer Center and USF,鈥� said , a researcher in Moffitt鈥檚 Integrated Mathematical Oncology unit. 鈥淚t was truly humbling and inspiring to see how the students took the initial ideas and completely transformed, designed and implemented this highly innovative device. We sincerely hope that these results lay the foundation for a clinical device that can help a lot of patients in different scenarios around the world.鈥�
The high praise received for the device inspired the team to pursue local and national innovation competitions. They first entered the Jabil Innovation Technology Challenge, a statewide competition open to Florida undergraduate, graduate and doctoral students. After winning the $10,000 first prize, the students set their sights on the annual , supported by the and VentureWell. This prestigious competition is open to teams from across the country and had previously been won by groups from universities such as Stanford and Columbia. This year, the .
鈥淚t鈥檚 incredibly gratifying to be acknowledged at this level, especially for something that we believe could one day save lives,鈥� Blocker said. 鈥淲e learned so much through this capstone experience and it really gave us the opportunity to use all of the knowledge and skills we鈥檇 gathered during our undergrad.鈥�
The group credits their undergraduate experience in USF鈥檚 Department of Medical Engineering for giving them the tools to create such an innovative and impactful device. All three graduated summa cum laude from the department with degrees in biomedical engineering. Since graduating, Yamamoto Alves Pinto has begun a doctoral program at Johns Hopkins University. Blocker is preparing to begin a master鈥檚 in biomedical engineering at the University of Cape Town in South Africa and Yarinsky is currently working as an engineer at Nilogen Oncosystems in Tampa.
The Department of Medical Engineering is a joint program between the 国产短视频College of Engineering and 国产短视频Health Morsani College of Medicine. It was first created through funding from the State of Florida鈥檚 preeminence program. In 2018, the Florida Board of Governors designated 国产短视频as a Preeminent State Research University, allocating more than $6 million in new funding to enhance research and student success activities in strategic areas. 国产短视频is one of very few universities to have a medical engineering department and just one of four in Florida to offer a Bachelor of Science degree in biomedical engineering.
As for the Eucovent, the team plans to publish this work and continue to improve the design while they await patent approval. They are also handing the project to another capstone group at 国产短视频to further the design and give other students the opportunity to contribute to a lifesaving device.
