Background
Bronchoalveolar lavage is a new technique developed on the basis of fiberbronchoscopy. The method is characterized in that a bronchoscope is used for injecting physiological saline into a bronchoalveolar and then sucking out the saline, and effective liquid on the surface of the alveolar is collected to check cell components and soluble substances of the alveolar. There are two methods of full lung lavage at one side of the canon double lumen tube row through general anesthesia and fiber bronchoscope lavage. The kit is clinically used for diagnosing various lung diseases, such as the clinical diagnosis, differential diagnosis, research on etiology, pathogenesis, curative effect evaluation, prognosis and the like of pulmonary alveolitis, pulmonary fibrosis, asbestosis, lung cancer, pulmonary cysticercosis, pulmonary alveolar proteinosis and the like.
Bronchoalveolar lavage is a method of injecting a fluid into a bronchoalveolar space and then aspirating it out to diagnose and treat a lung disease. Generally, a fiber bronchoscope is inserted into a certain section of a bronchus, and the lung is injected by physiological saline at 37 ℃ and then is sucked out by low negative pressure. The lavage liquid can be used for cell, microorganism, immunity and biochemistry examination to explore the etiology and pathogenesis of lung diseases and assist diagnosis; can also promote the discharge of alveolar foreign matters, inflammation or immunoreaction products by repeated lavage to achieve the treatment purpose.
While the following notes are included in the irrigation procedure, 1. during the procedure, trauma and coughing by the patient should be avoided, otherwise significant contamination of the mucus and blood may result. 2. The bronchoscope must be kept in place throughout the lavage procedure to prevent spillage of the lavage fluid and contamination of the airway secretions. 3. The negative pressure suction should be less than 80mmHg, otherwise the distal airway can collapse, affecting the amount of recovery. 4. During the irrigation and within 2 hours after the irrigation, vital signs and pulse oxygen saturation of all patients are observed according to a routine method, and corresponding oxygen therapy is given to the anoxic patients.
In the process of lavage, the lens of the electronic bronchoscope needs to be kept at a proper position all the time to prevent the lavage liquid from overflowing and the secretion of the atmosphere from being polluted; the flushing port is fixed at a proper position of the bronchus to prevent the flushing port from being deformed by water pressure to puncture the bronchus during flushing.

Based on the above embodiment, the technical problem that the present application intends to solve is that the tube 2a is susceptible to swing due to hydraulic force when irrigating the alveolus, so that the bronchus is easily punctured by the front end of the tube 2a, and the front end of the tube 2a is fixed and adsorbed on the bronchus wall by the negative pressure structure, so that the distal airway is easily collapsed. To this end, the present application secures the front end of the tube 2a in the bronchus by means of a first balloon 2b capable of half-occluding in the bronchus, so as to lavage the half-side alveoli of the lungs, and then the other half-side alveoli;
wherein "semi-occluded" is understood to mean that the first balloon 2b in the inflated state is occluded in the bronchus so that the front end of the tube member 2a is fixed in the bronchus to prevent puncturing of the bronchus during lavage, and at the same time, the bronchus at both sides of the occlusion are in a connected state so that the lavage fluid can fill the half-side alveoli of the lung;
one side of the bronchus is provided with a main bronchus, an upper lobe bronchus, a middle lobe bronchus and a lower lobe bronchus in sequence from top to bottom;
