Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a line-conduction ultrasonic bronchoscope for liquefying thick sputum.
Background
According to the case report of the new coronary pneumonia and the anatomical analysis of dead patients, the new coronary pneumonia is found to cause a large amount of sputum to be secreted by the lungs and trachea of the patients, so that the alveoli and the trachea are blocked, and the sputum blockage is caused. When more alveoli and trachea are blocked by sputum, the patient cannot breathe normally, the blood oxygen concentration is seriously reduced, and finally, tissue and organ damage, shock and even death are caused.
Bronchoscope sputum suction is an important method for solving the problem that sputum of patients with new coronary pneumonia, particularly critically ill patients, blocks alveoli and trachea. However, when the patient faces high-viscosity thick sputum, the bronchoscope often cannot suck out the high-viscosity thick sputum, and finally the patient cannot be rescued in time. When a higher negative pressure is used to aspirate sputum, damage to the tracheal tissue or pulmonary edema may easily occur.
At present, the main method for solving the thick sputum blockage is to dilute the sputum through medicines, but the medicine has longer action time for critically ill patients needing to be treated in time, the sputum needs to be discharged in the shortest time, and the long-time hypoxia is avoided.
