  • Needle based precision venturi flow-generator for positive pressure ventilation
    Patent number: 11793958
    Abstract: A flow generator for generating a mixed oxygen air flow, the flow generator including a body having a first inlet, a second inlet, an outlet, and one or more inner surfaces that define a first inner chamber in fluid communication with the first inlet and the second inlet, a second inner chamber in fluid communication with the first inner chamber, and a third inner chamber in fluid communication with the second chamber and the outlet of the body. The flow generator includes a connector disposed in the first inlet and a nozzle disposed within at least a portion of the connector and extending into the first inner chamber. The flow generator further includes an adapter engaged to the nozzle to form a fluid tight path such that the adapter connects to an external oxygen source and transports oxygen into the nozzle.
