For critically ill neurosurgery patients with uncontrolled respiratory and lung infections, the condition is aggravated due to excessive secretions blocking the airway. Suctioning sputum from the nose or mouth cannot completely remove the secretions, and the general suction tube cannot reach the deep airway for suction operation. At this time, the airway secretions should be sucked out under direct vision using a fiberoptic bronchoscope. However, the fiberoptic bronchoscope instruments and equipment currently used in hospitals are bulky, and the fiberoptic bronchoscope operation must be scheduled when used in the department, and the respiratory system cannot be explored at any time; secondly, the suction button on the operating lever of the current fiberoptic bronchoscope cannot achieve single-operation dilution and flushing, and another hand is required to increase the flushing and suction liquid, and the opening of the flushing and suction port weakens the suction negative pressure; at the same time, the insertion part is not protected and is easily contaminated before being inserted into the patient's airway. Therefore, there is an urgent need for an integrated fiberoptic bronchoscope in clinical practice to improve the defect that the disposable suction tube cannot fully suction sputum, and it can also partially replace the disadvantages of conventional fiberoptic bronchoscopes.
