The ventilator system of claim 7 further comprising a third proportional valve, an inspiratory safety valve, and a proximal end sensor, said inspiratory safety valve being connected between said oxygen concentration sensor and said humidifier, an inlet end of said third proportional valve being connected between said mixed gas flow sensor and said oxygen concentration sensor, said mixed gas pressure sensor being connected at a junction of said inlet end of said third proportional valve and said mixed gas circuit, an outlet end of said third proportional valve being connected to said inspiratory safety valve;
the near-end sensor is arranged at the air outlet end of the mixed gas circuit and used for monitoring the gas flow and pressure at the interface of a patient; when the gas pressure monitored by the near-end sensor exceeds a set value, the gas in the mixed gas circuit can be discharged to the outside through the inspiration safety valve.
