Made with 'primarily a garden hose, a lamp timer and electronic valve,' the ventilator, named the Robertson Ventilator, for less than $100, can be assembled in approximately 20 to 30 minutes.
JACKSON, Miss. — As states across the country beg for ventilators to help patients suffering with respiratory issues from COVID-19, the University of Mississippi Medical Center is building its ownDr. Charles Robertson, a UMMC pediatric anesthesiologist and the mastermind behind the idea, said he set out to make the"absolute simplest ventilator we can build with parts available in any city, you don't need special tools to put together and can be done quickly as the need arises.
Demonstrating the functionality of the machine at a news conference Tuesday afternoon, Robertson turned on a ventilator hooked up to a mannequin. The mannequin's chest began to rise and fall."The brain behind the thing is actually a lamp timer," he said."It's not fancy but it works. This would be available as a last resort if the numbers increase as we think they might.
As of Tuesday, UMMC staff had assembled 170 of the ventilators, Robertson said, doubling the hospital's capacity. They have parts to make 75 more. Dr. Richard Summers, associate vice chancellor for research for UMMC, addressed the shortage of conventional ventilators, saying,"as a contingency plan, we were looking for our state to be independent."The Robertson Ventilators have been tested and proven to be successful on both laboratory animals at UMMC and in simulation, Summers said, and"performed well, even in conditions that we would expect with COVID lung.
