Abstract
Device for volume controle high frequency oscillatory ventilation consists of high pressure oxygen/air blender, reduction valve, humidifier and heater. The mentioned system is connected to the jet of ventilatory node and tracheal tube.
The jet is inserted in working cavity, which is connected in longitudinal axis to the orifice of controle two-way valve, on other side in region of jet orifice is system connected to trachel tube by the juncting conduit. Two- way valve outlet is connected to reduction valve.
The juncting conduit is inserted vertically to longitudinal axis of working cavity. The orifice of juncting conduit is equiped by the flow and pressure senzor.
Two-way, two pole membrane valve is controled by the generator of pneumatic pulses.
