BURLINGTON, ON, Feb. 4, 2021 /CNW/ - The Diagnostic imaging team at McMaster University Hospital was concerned about the ultrasound technologists' lack of protection whilst sitting to the side of patients. Regular Face Shields exposed the sides of their face and neck as the patients were lying down and looking up at them. They wanted a better Face Shield with more protection.
The McMaster Manufacturing Institute (MMRI) set about designing an oversized face shield to protect the chin, neck, and sides of the head. When the prototype was proposed to the Hamilton Health Science (HHS) PPE Task Force for approval, "it turned out that the Anesthesia and Medical Reprocessing team at HHS was interested in similar protection".
