Example Embodiment

[0027] Such as figure 1 As shown, the intelligent hypoxia generating device system of the present invention includes a central parameter measurement and control system, a compressed air preparation device, a hollow fiber membrane separation unit, and a user terminal device that are sequentially connected through a pipeline. The compressed air preparation device includes The air filter 1, the air compressor 2 and the air fine filter device 4 are connected to the secondary phase. A compressed air storage tank 3 is arranged between the air compressor 2 and the air fine filter device 4. The air fine filter device 4 is heated The device 7 is connected to the hollow fiber membrane separation unit 8. The hollow fiber membrane separation unit 8 is connected to the flow control valve 10, the flow meter 11 and the open face mask 12 of the user terminal device through the product gas storage tank 9; the central parameter measurement and control system 13 is composed of a pressure control module, a temperature control module, an outlet oxygen partial pressure control module, a human physiological index measurement module, and a single-chip microcomputer acquisition control board. Among them, the pressure control module, temperature control module, outlet oxygen partial pressure control module and human physiological index measurement The modules are respectively electrically connected with the single-chip acquisition control board and controlled by the single-chip acquisition control board. The outlet oxygen partial pressure control module monitors the oxygen partial pressure of the product gas at the outlet of the hollow fiber membrane separation unit and compares it with the set value. The single-chip microcomputer collects the control board and sends instructions to the pressure control module to control the electronic control valve at the inlet pipe of the membrane separation unit To adjust the inlet pressure of the membrane separation unit to ensure that the oxygen partial pressure of the product gas at the outlet of the hollow fiber membrane separation unit is consistent with the set value. The human body physiological index measurement module includes an ECG measurement module and a blood oxygen saturation measurement module. The control principle diagram of the central parameter measurement and control system of the present invention is as follows figure 2 Shown.
[0028] In the whole system, the compressed air preparation device introduces the outside air, compresses it, increases the pressure, and uses it as the raw material gas of the product gas preparation system after purification; then the product gas preparation system (mainly composed of electric control valves, pressure gauges, heaters, hollow fiber Membrane separation unit and product gas storage tank) according to the set product gas output index requirements, adjust the pressure and temperature of the raw gas, enter the membrane separation unit for gas separation, and collect the product gas in the product gas storage tank for waiting Then, the open face mask is worn on the mouth and nose of the human face, and the product air is continuously delivered to the face mask for human inhalation. The flow meter 11 can visually display the output product air supply and breathing status; central parameter measurement and control system It consists of an inlet pressure control module, a temperature control module, an outlet oxygen partial pressure control module, a human physiological index measurement module, and a single-chip microcomputer acquisition control board. Its main function is to collect the gas outlet and inlet parameters of the hollow fiber membrane separation unit, according to the product The gas output index requirements are compared with the set parameters, and the gas outlet and inlet parameters of the hollow fiber membrane separation unit are adjusted and controlled to meet the set requirements.
[0029] When the present invention is working, the power switch is turned on, and the central parameter measurement and control system starts to work. The user can click on the oxygen partial pressure value of the required output product gas, and after confirmation, turn on the air compressor 2 to work. The outside air is purified by the air filter 1. Entering the air compressor 2, the air is compressed to form high-pressure air and is transported to the air storage tank 3. The fine filtering equipment 4 further filters out the trace moisture and oil contained in the high-pressure air, and then passes through the electric control valve 5 and the heater 7. It is transported to the hollow fiber membrane separation unit 8 for gas separation, and the product gas is collected in the product gas storage tank 9 for storage for later use. The pressure gauge 6 displays the pressure value set by the electric control valve 5. When in use, the user wears the open face mask 12 on the mouth and nose of the face, uses the flow control valve 10 to adjust the required output product air flow value according to the flow meter 11, and continuously transports it into the mask through the pipeline for the body to inhale. In order to save the consumption of output product gas, the open face mask 12 adopts a compensation bag design. When the human body exhales, the product gas entering the compensation bag increases its volume, which plays the role of storing product gas; The product gas in the compensation bag can be supplied to the human body for inhalation in time. In order to stabilize the gas separation efficiency of the membrane separation unit 8, it is necessary to control the temperature of the gas input to the membrane separation unit 8 with the heater 7.
[0030] The outlet oxygen partial pressure control module of the central parameter measurement and control system collects the oxygen partial pressure value of the output product gas monitored by the oxygen meter, and compares it with the set value, and adjusts the electronic control valve through the inlet pressure control module to make it The set pressure meets the requirements. Gas pressure, concentration detection and control such as image 3 As shown, the user sets the desired product gas oxygen partial pressure through the computer, and transmits it to the single-chip computer through the data line. The single-chip computer collects the gas concentration data monitored by the oxygen meter, and processes the data, and performs the data transmission with the computer After comparative analysis, the electronic control valve is controlled to realize the automatic control of the pressure and concentration of the measured gas. At the same time, the actual pressure and concentration of the measured gas collected by the single-chip microcomputer are displayed by the computer. Temperature detection control such as Figure 4 As shown, the user can set the desired temperature through the computer and send it to the single-chip microcomputer through the data line. The single-chip computer collects the temperature data of the temperature acquisition module, and processes the data, compares and analyzes the data sent from the computer, and compares the temperature. Control module control, so as to realize the automatic control of the gas temperature of the pipeline under test. At the same time, the temperature value of the measured pipeline gas collected by the single-chip computer is displayed by the computer. The human body physiological index measurement module monitors and displays the measured values ​​of various physiological indexes of the human body in a timely manner, providing a basis for judging the changes in human body functions.
[0031] The present invention adopts a personal mask type air supply method, which can accurately control the proportion of oxygen and nitrogen components of the output product gas, is convenient to carry, and avoids uneven mixing of training gas in a fixed hypoxic room, poor control of hypoxia indicators, and repeated inhalation of the human body to exhale Carbon dioxide is not conducive to human physiological health and health, and problems such as high energy consumption.
