摘要：
A non-invasive ventilation patient interface comprises a fresh gas entry port, an exhaust gas vent port, and a filter media disposed in the exhaust gas vent port. The fresh gas entry port is configured for coupling with a fresh gas supply. The exhaust gas vent port is configured for allowing expulsion of exhaust gas from the patient interface in response to exhalation of a patient. The filter media is configured for filtering contagious from the exhaust gas, diffusing the exhaust gas, and controlling an expulsion flow of the exhaust gas through the exhaust gas vent port.
