The present disclosure relates to a lung classification model training method, a lung image classification method and a device thereof. The training method comprises: performing regional feature extraction on each first lung image to obtain a first multi-region feature set, and performing regional dimension feature correlation analysis on the first multi-region feature set to obtain a first fusion feature set containing a non-redundant feature set and a correlation feature set; and performing iterative training of a lung classification model according to training label data and a plurality of first fusion feature sets, wherein the non-redundant feature set represents independent feature information with independent distinguishability of a plurality of lung regions, the correlation feature set represents complementary feature information between the plurality of lung regions, and the fusion feature set has precise representation capability of independent features of a single lung region and complementary features across regions, thereby breaking through the adaptation limitation of a fixed application scenario and improving the accuracy and robustness of the lung classification model.

This invention discloses an auxiliary ventilation device for one-lung positive pressure ventilation (CPAP) to prevent gas embolism, comprising a gas source connector, a precision flow regulating valve, a pressure generating and display module, and a patient connector. One end of the gas source connector is connected to the inlet of the precision flow regulating valve, and the other end is used to connect to a hospital central oxygen supply or a high-pressure oxygen cylinder. The outlet of the precision flow regulating valve is connected to the inlet of the patient connector, and the outlet of the patient connector can be directly connected to the affected side interface of a single-lumen endotracheal tube or a double-lumen bronchial tube. The pressure generating and display module is installed on the patient connector. This device addresses the problems in existing technologies, such as the lack of dedicated CPAP equipment for gas embolism prevention, the inability to visualize and adjust pressure, and the inability to accurately maintain pressure within a safe and effective pressure window (5~10 cmH2O), thereby achieving active, quantitative, and controllable gas embolism prevention during surgery.
