专利汇可以提供Respiratory device专利检索,专利查询,专利分析的服务。并且PURPOSE: To optimize the oxygen concentration of respiratory air by mixing a high concentration oxygen with the air, and controlling the oxygen concentration of the respiratory air so as to be a set value predetermined to a set standard of oxygen concentration.
CONSTITUTION: Each of detection signal of the oxygen concentration of respiratory air by an oxygen concentration detecting means 46, the aircraft altitude by an altitude sensor 22, and of the aircraft acceleration by an acceleration sensor 23 are inputted from the input and output device 25 of a microcomputer 24 to a control processing unit 26, which compares the respiratory oxygen concentration with an oxygen concentration predetermined to the altitude and acceleration, and outputs the control signal according to the deviation to operating systems 43, 45 through the input and output device 25. The operating systems 43, 45 operate flow rate control valves 42, 44 to render the oxygen concentration of the respiratory air in which high concentration oxygen is mixed with high pressure air to the predetermined set value. Thus, the respiratory air having the optimum oxygen concentration can be supplied.
