Feature: It is device according to the principle of open jet ventilator can ventilate with not only high frequency and low volume of humidifying but also regular frequency and great volume. A. When the ventilation technique with open high frequency and low humidify volume is adopted, the airway pressure is low with little effect of oxygen compound is good and the oxygen partial pressure can be increased rapidly. While the one with regular frequency and great humidify volume is adopted, CO2 can be ejected easily. B. Convenient connecting, it can be connected through the nasal and endotracheal tube. C. The ventilation mode with high frequency and low humidify volume will not easily produce pressure hurt. D. The effect of oxygen dispersion is so good that the tested beastie can stand for a long time. E. Adjustable oxygen concentration, the ventilation mode with continuous oxygen stream and good humidifying effect can ensure beastie to respire independently. F. Be fit for manual ventilation test for monkey, rabbit, dog etc. G. Configured with multiform ventilation conduit for beastles or connected with gas source, in addition. Specifications: Frequency: 8~150 breaths/min I/E ratio: 1: 1~1: 3 and inverse ratio Driving Pressure: 0~0.08MPaGas source: High-pressure oxygen source or air compredsor. The input pressure is not more than 0.16MPaHigh-pressure gas source: 0.16MPaOutput Limit of reductor: Not less than 0.16MPaVentilation Mode: HFJV(High Frequency Jet Ventilation); CPAP(Continuous positive airway pressure), Manual Control Mode.
