Feature It is widely used for clinical salvaging and revival also is a dedicated device used for respiration salvaging on emergency ambulance. A. An opening system is designed to avoid leakage of airway, when ventilating, the intubations may have no casing bag. Little tube may be used for ventilation when resistance of expiration is small, so that mucose won't be hurt easily. B. Airway is open during ventilation, suction and ventilation can be done synchronously, so good effectiveness of oxygen combination can be shown without inspiration and expiration synchronizing. C. Lower airway pressure is good to increase blood discharge and decrease encephal pressure. D. Suction device, its driving negative pressure is adjustable. E. Accumulator jar, it can be used continuously for not less than four hours after being charged. F. The system disposes completely with laryngoscope, inlet intubation, catheter of tracheotomy, nasal prongs tube, and air tube etc. Specifications Frequency: 10 150 breaths/min I/e ratio1:1, 1:1.51:3 and inverse ratio Sigh:6breaths/min, Cpapf1.5kpaff Suction negative pressure:-0.050mpa Driving pressure 00.15mpa Constant volume ventilation: t=10min, i/e=1:1.5 Adults:f(100):f(20)=7:3, tidal volume=550ml/time, driving pressure=0.06mpa Children:f(100):f(20)=7:3, tidal volume=350ml/time, driving pressure=0.04mpa Storage battery:4ah, automatic charge when 12v Most jetting volume:f1400ml/time Oxygen concentration adjustable:40%-90% Alarm: alarm when battery pressure is lower than 11v; alarm when the oxygen pressure is lower than 0.01mpa; alarm with sound and light when no gas Ventilation mode:hfjv(high frequency jet ventilation);cpap(continuous positive airway pressure), hfjv+sigh;constant volume ventilation.
