University of Florida designing low-cost, 'open source' ventilator made from hardware store items

GAINESVILLE, Fla. -- A professor of anesthesiology at the University of Florida is building an "open source" ventilator out of common items from hardware stores, in an effort to meet the desperately high demand internationally due to the coronavirus pandemic. Decades ago, Dr. Samsun Lampotang helped build a minimal-transport ventilator while he was a mechanical engineering student at UF. That ventilator became a commercial success, university officials said.

Now, he is working with researchers at UF to build a new prototype, using "plentiful, cheap components" that could be copied around the world.

Lampotang sent his lab's lead engineer, Dr. David Lizdas, to Home Depot to buy a variety of items, including air-tight PVC water pipes and lawn-sprinkler valves.

Their mission: To "MacGyver" the items into an open-source ventilator that they will then make publicly available.

“The way I looked at it is, if you’re going to run out of ventilators, then we’re not even trying to reproduce the sophisticated ventilators out there,” Lampotang said in a university statement. “If we run out, you have to decide who gets one and who doesn’t. How do you decide that? The power of our approach is that every well-intentioned volunteer who has access to Home Depot, Ace or Lowe’s or their equivalent worldwide can build one.”

Lampotang is an inventor with 43 patents belonging to UF. However, he said he will not try to patent the ventilator. Instead, with UF's approval, he wants to provide it as "open source" for engineers and hobbyists across the globe to build in order to help curb the skyrocketing demand for the life-saving devices. UF officials said the machine can be built for as little as $125 to $250.

The team is working on adding safety features to meet regulatory guidelines. They will then run engineering tests to determine safety, accuracy and endurance.

“We want to reach the whole world, and The Gator Nation,” Lampotang said. “We have UF graduates from all over the world. There’s already a network of people who can contribute in disseminating the technology if it’s needed in the next few weeks.”

Beyond the coronavirus pandemic, Lampotang said he hopes the ventilator can be useful in the long run, as well.

“When all this comes to pass and the world settles down, we hope it will be repurposed for use in underdeveloped countries, so they can build a safe and inexpensive ventilator for themselves,” he said.
