Abstract: PURPOSE: High risk procedures such as intubation, tracheotomy for critically ill 2019-nCoV patients were one of the most important factors that increased the risk of healthcare workers (HCWs)'s infection. METHODS: One anti-spray isolation device was developed to reduce virus infection during high risk procedures. Operators performed surgery through two holes on the isolation device, while not affected. RESULTS: This isolation device was patent and applied successfully in seven critically ill 2019-nCoV patients who received tracheotomy. Then it went into production and had been transported to Wuhan medical institutions. CONCLUSIONS: At present, this isolation device had been used in clinical practice and received good feedback. It was believed that the device would provide well protection for front-line HCWs and reduce their infection risk.
