[0010] The present invention will be further described below in conjunction with accompanying drawing.
[0011] figure 1 As shown, a ventilator driven by a low-flow small medical air compressor includes a PLC control system 1 , an air-oxygen mixer 2 , an oxygen channel 3 and an air channel 6 . The gas in the oxygen channel 3 and the air channel 6 is mixed by the air-oxygen mixer 2 and sent to the patient. The oxygen channel 3 is connected to a high-pressure oxygen source, and the oxygen channel 3 is provided with a first electronically controlled proportional valve 4 and a first flow sensor 5 in sequence; The air channel 6 is connected to the low-flow small medical air compressor 7, the second electronically controlled proportional valve 8, the Venturi device 9 and the second flow sensor 10; the first electronically controlled proportional valve 4, the first flow sensor 5, the second electronically controlled Both the proportional valve 8 and the second flow sensor 10 are con...
