TKR-300JII COMPUTERIZED HIGH-FREQUENCY FIRST-AID VENTILATOR

　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 intubation 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 wentilarion, 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.
