With rural and small clinics in mind, professor uses COVID-19 grant to create low-cost respiratory device
Dr. Alessander Danna-dos-Santos working from home to design a low-cost spirometer.
KALAMAZOO, Mich.鈥擜 computerized spirometer, which monitors lung efficiency, can cost as much as $2,000. Dr. Alessander Danna-dos-Santos, a 麻豆传媒 professor, is developing a compact device with components that cost less than $150. He aims to make it widely available for merely the price of parts, manufacturing and shipping so smaller clinics and rural areas in Michigan can have access to this technology.
Danna-dos-Santos recently received one of five University grants for COVID-19 response-related research, and he has spent the summer working from home with his own equipment to create the dedicated hardware and software.
鈥淚 decided to put the skills I have toward making technology equipment accessible to small health care clinics,鈥 he says.
Given his professional and academic training acquired in multiple organizations and countries, Danna-dos-Santos is the type who has his own 3D printer and is a self-taught coder.
The spirometer idea began by recognizing a need, says Danna-dos-Santos, who is a certified physical therapist in both the United States and his native Brazil. The 2002 SARS, or severe acute respiratory syndrome, epidemic heightened the need for short- and long-term respiratory care. This year鈥檚 COVID-19 pandemic increased that need exponentially.
鈥淲e are now going through a very similar, but much much more amplified, health crisis with repercussions,鈥 says Danna-dos-Santos.
A computerized spirometer assesses how well lungs work by measuring the forces of air flow involved during exhalation and inhalation. It鈥檚 used to diagnose and monitor conditions that affect breathing, such as asthma, pneumonia and viral infections as well as the success of interventions.
Danna-dos-Santos鈥 spirometer measures 2-by-6 inches and includes durable, low-cost materials that are easily replaceable. He will be applying Institutional Review Board approval to initially test the device with Unified Clinics patients, and he hopes by December he鈥檒l have all the data he needs to apply for a patent.
His final goal is to team up with a manufacturer for widespread distribution.
Danna-dos-Santos says he has no intention of profiting from his design. He does, however, want the device to particularly benefit rural medical centers and other financially hard-pressed locations that serve the underprivileged.
He says he believes the United States鈥 notoriously expensive and disproportionate health care system need not deter the development of more cost-effective solutions.
The bridging of 鈥渂asic science and clinical care鈥 is all that鈥檚 required, he says.
鈥淚t鈥檚 not very difficult for me to put into context. In my mind, it is simple. Anyone can buy most of these parts online. The problem is expertise. This project needs software development. It needs an interface. I have basic skills in these areas,鈥 Danna-dos-Santos explains. 鈥淚 understand what buttons to push.鈥
He learned to push those buttons as his career progressed. In Brazil and in the U.S., he says he had inspiring and innovative mentors whose work was not based on the presence of sophisticated lab equipment but on their capacity to develop simple solutions to complicated problems based on solid scientific principles. As a result, his work has rendered the development of systems for neurological diagnosis and other research that has benefited the community.
Since then, Danna-dos-Santos has furthered that service philosophy by teaching others to identify and conceive methods for meeting needs. For instance, a decade ago at his previous academic appointment, he redirected his laboratory to welcome international fellows, minorities and health care providers, all with the goal of making scientific research accessible and practical.
In collaboration with Dr. Adriana M. Degani, he operates a balance laboratory at WMU's Unified Clinics with the objective of evaluating and treating older citizens suffering from higher risks of falls.
Some of Danna-dos-Santos鈥 research and clinical initiatives have also involved technological innovations to assess and treat patients suffering from the effects of traumatic brain injury, and he's developing algorithms pertaining to motion control.
Danna-dos-Santos says his or any innovations 鈥渁re not going to replace a good health care provider, but they鈥檒l help a good health care provider be more efficient in what they鈥檙e doing.鈥
