Abstract
An exhalation device for a non-invasive ventilator, configured to reversibly convert between a passive ventilation configuration and an active ventilation configuration, comprising: (i) a housing with a first end and a second end, the housing defining a gas flow path extending between the first end and the second end; (ii) an exhalation port configured to passively release gas to the environment; (iii) an internal diaphragm positioned at an interface between the exhalation port and the housing, configured to allow release of gas exhalation; and (iv) an adapter comprising an adapter exhalation port and configured to reversibly engage the exhalation port to define a controlled exhalation flow path from the exhalation port to the adapter exhalation port, and comprising an internal air flow control configured to actively control the flow of exhalant through the controlled exhalation flow path.
