Abstract:
Objective To design and manufacture a hypobaric cabin simulator for experimental animals.Methods The simulator was composed of a fully transparent working chamber,an electrical chamber,a pressure control component and a program control component,which had its body made of polymethyl methacrylate plastics,the hatch made of metal plate and support by reinforced metal bar.The air inside chamber was exhausted by the diaphragm vacuum pump,the air inflow was controlled by proportional valve,and the inner pressure and the speed of rise and decline were exactly controlled by the balance of inflow and exhaust.Results The new type of hypobaric cabin simulator had the characteristics of accurate pressure control,low fluctuation range and controllable up and down time,low noise as well as adaptable air exchange rate.Conclusion The new type of hypobaric cabin simulator matches the national standard for experimental animals,and can be used in making the animal model of high altitude diseases.
