The control-monitor, used in combination with a percussive ventilation breathing head and internal reciprocating injector shuttle, includes in a casing a generator, sensory pulse amplitude, frequency and MAP modules and a gas amplitude and pulsatile frequency control knobs. First and second AMP control indicia include a bent conical AMP indicia (a wide span indicating greater amplitude, a narrow span indicating lesser amplitude) and a single waveform with an adjacent double-headed arrow vertical line. First and second F control indicia include a bent conical F indicia (a wide span indicating greater F and a narrow span indicating lesser F) and multiple waveforms with an adjacent double-headed arrow horizontal line.

A portable oxygen-air blender including a gas distributor valve, a plurality of venturi valves, and an oxygen monitor. The gas distributor valve selectively routes the flow of oxygen from a compressed gas reservoir into one of several venturi valves to be blended with atmospheric air in a predetermined ratio. The blended oxygen-air mixture may be safely delivered to neonatal patients who require a specific concentration of oxygen to breathe. A monitoring system allows the user to verify concurrently that the patient is receiving the correct blend of oxygen and make adjustments to the patient's treatment.

Method and apparatus for providing percussive ventilation therapy to a patient airway preferably includes at least one driver unit configured to provide pressurized, non-pulsate gas. At least one patient interface device preferably has structure configured to (i) receive the pressurized, non-pulsate gas from the at least one driver unit and transform it into a pulsed and pressurized gas, and (ii) supply at least one sub tidal volume of pulsed and pressurized gas to a patient through a patient connection orifice. At least one flexible tube is preferably configured to provide pressurized, non-pulsate gas from the at least one driver unit to the at least one patient interface device. Preferably, at least one portion of the patient interface device is disposable, and another portion may be reusable. Preferably, the invention uses Adaptive Dynamic Subtidal Ventilation technology.

An apparatus such as a fluid mixer, suitable for use with a respirator, including a venturi nozzle for flow of a pressure-controlled fluid; an ambient fluid aperture in fluid communication with the venturi nozzle; a fluid port; a pressure force multiplier in fluid communication with the fluid port; and a valve moveable relative to the venturi nozzle between a start flow position and a stop flow position; where the pressure force multiplier is configured such that fluid forced into the fluid port actuates the valve relative to the venturi nozzle; and where the pressure force multiplier is configured such that fluid withdrawn from the fluid port actuates the valve relative to the venturi nozzle.

A nasal cannula includes a prong formed from an inner cylindrical wall surrounded by an outer cylindrical wall, a base connecting the inner cylindrical wall to the outer cylindrical wall and an air channel formed between the inner and outer cylindrical wall. The inner cylindrical wall defines a bore through which air may freely flow. The nasal cannula additional includes a connector fluidly connected to the air channel and configured to provide flow communication between the air channel and an external device connected to the connector.

A liquid introducing device transfers a fixed amount of liquid medicine into atomized particles. The liquid medicine is connected to the liquid introducing device which allows the users to quickly replace the bottles and avoid cross infection between different medicines. The liquid introducing device is powered by electric power to atomize the liquid quickly. The liquid introducing device includes a chamber which cooperated with an electro-magnetic valve switch which controls a fixed amount of air in the chamber such that the fixed amount of the air can be pressurized and output stably. The pressurized air passes through the tube without delay and loss.

A ventilator includes an enclosure, a tubing configured to receive an input gas, and a flow outlet airline in fluid communication with the tubing. The flow outlet airline includes an airline outlet. The ventilator further includes a breath detection airline including an airline inlet. The airline inlet is separated from the airline outlet of the flow outline airline. The ventilator further includes a pressure sensor in direct fluid communication with the breath detection airline. The ventilator includes a controller in electronic communication with the pressure sensor and an internal oxygen concentrator in fluid communication with the tubing. The internal oxygen concentrator is entirely disposed inside the enclosure.

A ventilator includes a bidirectional breath detection airline and a flow outlet airline. The flow outlet airline includes an airline outlet. The ventilator further includes a breath detection airline including airline inlet. The airline inlet is separated from the airline outlet of the flow outline airline. The breath detection airline is configured to receive breathing gas from the user during exhalation by the user via the airline inlet. The ventilator further includes a pressure sensor in direct fluid communication with the breath detection airline. The pressure sensor is configured to measure breathing pressure from the user and generate sensor data indicative of breathing by the user. The ventilator further includes a controller in electronic communication with the pressure sensor. The controller is programmed to detect the breathing by the user based on the sensor data received from the pressure sensor.

A gas venturi connector includes a venturi body having an open first end and an opposing second end that includes a gas port for connection to a supplemental gas source. The venturi body includes a first air entrainment window and a second air entrainment window spaced from the first air entrainment window. Each of the first entrainment window and the second air entrainment window has an L-shape. The connector also has a movable shutter that rotates about the venturi body and includes a third air entrainment window and a fourth air entrainment window spaced from the third air entrainment window, wherein registration between the first and third air entrainment windows and the second and fourth air entrainment windows define a degree of air entrainment and the concentration of the supplemental gas delivered to the patient.
