WesternU: Research team develops clinically-validated 3D printed stethoscope

April 10, 2018

A team of researchers have developed an open-source, clinically validated template for a 3D printed stethoscope for use in areas of the world with limited access to medical supplies – places where a stethoscope could mean the difference between life and death. “As far as we know this is the first open-source medical device that has been clinically validated and is widely available,” said Dr. Tarek Loubani, associate professor at Western University’s Schulich School of Medicine & Dentistry, associate scientist at Lawson Health Research Instituteand an emergency room physician at London Health Sciences Centre. Loubani spent time working as an ER physician in hospitals in Gaza during wartime when medical supplies were often scarce. “We wanted physicians and allied health care professionals to be able to have something that was high quality. This study found that the acoustic quality was the same in our stethoscope as in a premium brand stethoscope.” Read the full article here.

Toronto Star: McMaster researchers develop transparent patch to detect pathogens like E. coli in packaged foods

April 10, 2018

Researchers at McMaster University have developed a transparent test patch for food packaging that detects the presence of potentially deadly bacteria like E. coli, with the aim of telling consumers and the grocery industry whether a product is safe to eat. Dubbed “Sentinel Wrap,” the patch triggers a molecular signal that a disease-causing agent has contaminated products like meat, bottled water or milk. “Right now, if you want to know if there’s any contamination in a food sample, you need to bring it into a lab ... and it takes at least a day or two to find out if there’s any pathogen present in that food sample,” said mechanical-biomedical engineer Tohid Didar, one of the product’s developers.
