The Research And Design Of A New Kind Of Normobaric Hypoxia Cabin

The study of hypoxia has been a research hotspot in the field of biology and medicine, in recent years, along with the extensive development of hypoxia research, sports and social masses has generated great interest on hypoxia and hypoxia training. With the improvement of people’s living, traveling to Tibet is also increasing, and this has become one of the potential power of hypoxia research.The main equipment of hypoxia research are Altitude chamber, Hypoxia cabin and Breathing mask. This paper simply introduced, and analyzed its advantages and disadvantages. On this basis, we put forward a new kind of hypoxia cabin, which integrated with altitude chamber and Hypoxia cabin.The main works of this paper:(1) Some basic problems of hypoxia cabin was studied. This includes the leakage model, airtight requirement, water pressure on the effect of alveolar height, carbon dioxide processing and so on.(2) the overall design of the system is introduced in detail. This includes nitrogen preparation system, control system, signal acquisition system, and the hardware and circuit design are described. In view of the class characteristics, this paper puts forward an optimization algorithm combined with empirical formula and PI control (3) on the basis of hypoxia cabin, we carried out a large-scale hypoxic training, which fully confirmed the validity of the cabin. The cabin can carry out hypoxia pre-adapting training and hypoxic tolerance evaluation.
