Abstract: A valve cassette for a turbine mechanical ventilator includes a plurality of diaphragm check valves, a plate including a plurality of seats configured for receiving said plurality of diaphragm check valves, and at least one connecting element configured for fixing valve cassette to a turbine housing inlet. Each of said plurality of diaphragm check valves includes a flexible membrane and a plug. Each of said plurality of seats includes a bore for receiving said plug and a plurality of openings through which air is configured to flow through the valve cassette.

Abstract: A ventilator console includes an inhalation port, an exhalation port, a console sampler to sample pressure or flow at the exhalation port and at least one sensor to sense at least one of pressure and flow velocity. The ventilator console additionally includes at least one external control port that provides an interface for flow or pressure communication between the at least one sensor and a tube connected to a patient circuit and a three-way valve integrated into the at least one external control port. The three-way valve is connected to the at least one sensor via a common port and toggles between establishing flow or pressure communication to the console sampler and establishing flow or pressure communication to the external control port.

Abstract: A reciprocating device, comprising: a motor; at least one crank mechanism attached to the motor; at least one rod attached to the crank mechanism; and at least one sleeve surrounding at least a portion of the at least one rod, adapted to dampen optional vibrations of the rod.
