“Lonnie called and asked, ‘Can we make ventilators? Can we do something to make a difference?’” said Friend. “I said, ‘My group is supposed to be good at making medical devices and what are we doing this for unless we’re doing it for a purpose like this?’”

UC San Diego Engineers, Doctors Upgrading, Testing Ventilators To Fight COVID-19

UC San Diego Engineer James Friend, who is also working in this lab, said there's some anecdotal evidence that ventilators have been split between patients in Italy and New York. "It’s unclear whether it’s been successful and just how much it's been tried. It's likely that it indicates more about the desperate nature of the situation, rather than whether it's a reasonably good approach to this sort of issue," he said.

UCSD researchers develop ventilator that can be made quickly, cheaply

The project was overseen by Professor James Friend, who works in the School of Engineering and School of Medicine. The device is essentially an bag valve mask that has been outfitted with an automatic pumping arm, created with pieces made by 3D printers and waterjet cutters. “Whatever the simplest, quickest fastest way to produce the safest parts is,” said Friend. “we choose that.”

The University of California reports that the team, led by Dr. Lonnie Peterson and Prof. James Friend, including Indian Americans Aditya Vasan, a graduate student; and Drs. Hemal Patel and Preetham Suresh; as well as graduate students William Connacher, Jeremy Sieker and Reiley Weekes and others; kick-started the project several weeks ago when news started to trickle in that communities in Northern Italy with widespread COVID-19 were in dire straits.

“One of the biggest things we heard was that there weren’t enough ventilators to treat all of the patients coming into the hospitals,” said James Friend, a professor in the Department of Mechanical and Aerospace Engineering and the Department of Surgery at UC San Diego. “It’s clear that if we’re not careful, we might end up in the same situation.”

Medical Devices for Low- and Middle-Income Countries: A Review and Directions for Development Journal of Medical Devices

2020

The development of diagnostics and medical devices has historically been concentrated in high-income countries, despite a significant need to expand healthcare services to low- and middle-income countries (LMIC). Poor quality healthcare extends beyond LMIC to underserved communities in developed countries.

Enabling Rapid Charging Lithium Metal Batteries via Surface Acoustic Wave‐Driven Electrolyte Flow Advanced Materials

2020

Both powerful and unstable, practical lithium metal batteries have remained a difficult challenge for over 50 years. With severe ion depletion gradients in the electrolyte during charging, they rapidly develop porosity, dendrites, and dead Li that cause poor performance and, all too often, spectacular failure.

Rapid and Accurate Pressure Sensing Device for Direct Measurement of Intraocular Pressure Translational Vision Science & Technology

2020

Intraocular pressure (IOP) is the primary modifiable risk factor for glaucoma. Current devices measure IOP via the dynamic response of the healthy cornea and do not provide the accurate IOP measurements for patients with altered corneal biomechanics. We seek to develop and test an accurate needle-based IOP measurement device that is not cornea dependent.
