R.I. nurse invents N95 mask preserver

A local nurse invented an N95 mask preserver. "There is nothing like this in the entire United States," said Timothy Aurelio, who has been an emergency room nurse at Roger Williams Medical Center for more than 25 years. This time last year, he said, was eye opening as health workers, due to a shortage of personal protective equipment (PPE), have had to use and reuse their N95 masks.
