Background

The main cause of some lung tissue diseases, such as pneumoconiosis, pulmonary alveolar proteinosis, radioactive dust inhalation and the like, is the deposition of abnormal substances in the lung, patients often have difficulty in breathing and blocked lung function, even threaten the life of the patients when the conditions are severe, and the life quality of the patients is significantly influenced. Particularly, in China, the proportion of patients with occupational diseases of the pneumoconiosis is quite high, according to statistics, the number of newly increased pneumoconiosis patients reaches 1 ten thousand every year, and the conventional treatment method cannot remove abnormal substances in the lungs of the patients, so that the affected lungs are subjected to fibrosis in different degrees. At present, the most direct and effective method for treating the abnormal substance pulmonary deposition diseases is whole-lung lavage (WLL), wherein WLL can effectively eliminate abnormal substances deposited in an alveolar cavity, a bronchiole and a part of pulmonary interstitium, such as protein-like substances, dust-swallowing alveolar macrophages and inflammatory factors, fibrosis factors and the like generated by the alveolar macrophages, and has the effects of removing etiology, improving respiratory function and relieving symptoms.

At present, the lung respiratory lavage technology is mainly improved on a canning device, for example, CN207837949U provides a multichannel large-capacity lung lavage device and a multichannel large-capacity lung lavage drainage device, the pipelines of two paths of gas are mutually communicated and blown out by the same respirator, the pressure and frequency of the two paths of gas are completely synchronous, so that lavage liquid in the left lung/right lung of a patient can be prevented from entering the right lung/left lung of the patient to cause mutual infection between the right lung and the left lung, and meanwhile, the change of thoracic cavity pressure and the change of hemodynamics are facilitated; CNCN102119039A provides a catheter assembly for sample collection in non-bronchoscopic bronchoalveolar lavage procedures that improves patient safety, comfort and economy, and reduces the risk of contaminants from the upper respiratory tract passing into the lower lung through improvements to non-bronchoscopic BAL apparatus.

However, in the field of lung respiratory lavage, the structure of the device is complex, a corresponding means is not provided for intelligently controlling the lung respiratory lavage device, the problems of long time consumption and low efficiency of lung lavage still exist, in addition, in the actual operation, lavage liquid is easy to enter the lung at one side from the lung at the other side, and the cross infection of the two lungs is caused, in addition, the amount of the lavage liquid and the recovery liquid is difficult to control by the conventional device, and the secondary damage to the lung organs is easy to cause; complications of pulmonary lavage are common and seriously affect the safety, comfort and economy of patients.
