Working principle: in the variable frequency mode, the respiratory state of the breathing machine is judged by detecting the change of the air flow in the pipeline, when the atomizing host 2 detects the air flow generated in the pipeline in the respiratory state of the breathing machine, an electric signal is sent to the controller 3, and the controller 3 drives the atomizing host 2 to atomize and administer the liquid medicine in the same ventilation pipeline; when the atomization host 2 detects that the breathing machine is in an inhalation state, the liquid medicine is not atomized; in the constant frequency mode, the continuous atomization of the liquid medicine can be performed without detecting the breathing state of the breathing machine. And the sensor 209 used to detect the flow of gas in the gas chamber may be a gas flow sensor or a gas pressure sensor. The difference is that the gas pressure sensor can detect the gas pressure, when the sensor 209 of the atomizing host 2 detects the gas flow, the sensor sends corresponding electric signals to the controller 3, the main control unit reads positive numbers to represent that the gas pipeline is in positive gas pressure, namely, the breathing machine is in an expiration state, meanwhile, the atomizing host 2 is driven to atomize, and atomized liquid medicine enters the mouth of a patient together with the gas supply of the breathing machine through the mouth of the three-way pipe 1 and the mask. On the contrary, the negative number read by the main control unit represents that the gas pipeline is internally provided with gas negative pressure, namely the breathing machine is in an inhalation state at the moment, and the main control unit should control the atomizing main machine 2 to stop atomizing at the moment. The gas flow sensor 209 can detect the instantaneous flow and direction of the gas, the positive and negative of the data read by the main control unit indicate different flow directions of the gas, for example, the positive number can represent that the gas flows from the mouth of the ventilator to the inside of the three-way pipe 1, i.e. the ventilator is in an expiration state at the moment; the negative number represents the flow of gas from the inside of the tee 1 to the mouth of the ventilator, i.e. the ventilator is in the inspiration state, and whether the atomizing host 2 sprays in different states is consistent with the gas pressure sensor 209.
What has been described above is merely some embodiments of the present invention. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the invention.
