Mechanical ventilator with oxygen concentrator

A ventilator, comprising:

• an enclosure;
• a tubing configured to receive an input gas;
• a flow outlet airline in fluid communication with the tubing, wherein the flow outlet airline includes an airline outlet, and the flow outlet airline is configured to supply an output gas to a user via the airline outlet;
• a breath detection airline including an airline inlet, wherein the airline inlet is separated from the airline outlet of the flow outline airline, and the breath detection airline is configured to receive breathing gas from the user during exhalation by the user via the airline inlet;
• a pressure sensor in direct fluid communication with the breath detection airline, wherein the pressure sensor is configured to measure breathing pressure from the user, and the pressure sensor is configured to generate sensor data indicative of breathing by the user;
• a controller in electronic communication with the pressure sensor, wherein the controller is programmed to detect the breathing by the user based on the sensor data received from the pressure sensor;
• an adjustable air entrainment device in fluid communication with the tubing configured to entrain the input gas flowing through the tubing, the air entrainment device comprising:
• a first inlet configured to receive a compressed gas, wherein the first inlet specifies a first annular chamber;
• a second inlet configured to receive the input gas, wherein the second inlet specifies a second annular chamber in fluid communication with the first chamber of the first inlet;
• a ring nozzle in fluid communication with the first inlet and the second inlet configured to receive the compressed gas from the first inlet and the gas from the second inlet, wherein the ring nozzle is adjusted automatically by an electromechanical mechanism;
• a device body in fluid communication with the ring nozzle comprising a convex inner surface specifying a third annular chamber;
• and
• an outlet in fluid communication with the device body;
• a blower in fluid communication with the tubing;
• a first ball valve and a second ball valve;
• a first gear, a second gear, and a third gear, wherein the first gear is coupled to a human machine interface to control the first ball valve and the second ball valve such that activating the human machine interface causes the first gear to rotate, the first gear is meshed with the second gear such that rotation of the first rotational direction causes the second gear to rotate in an opposite, second rotational direction;
• wherein the second gear is coupled to the first ball valve such that rotation of the second gear in the second rotational direction causes the first ball valve to close;
• an internal oxygen concentrator in fluid communication with the tubing;
• and
• wherein the oxygen concentrator is entirely disposed inside the enclosure.
