Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a directional sputum suction tube. Background Art
[0002] The method of using a suction tube is to first test the patency of the suction tube before formal suction. Let the patient raise his head and lean back, use a tongue depressor to open the patient's mouth, and insert the suction tube into the patient's trachea while the patient inhales. Insert the suction tube downward to a certain depth, close the side hole by hand, and perform suction. Especially for patients who need long-term suction, when placing the suction tube for such patients, it is not placed through the mouth, but through the nasal cavity, which greatly increases the difficulty of operation. Therefore, the suction tube often enters the esophagus by mistake due to the difficulty in controlling the direction, and cannot enter the trachea. After repeated debugging operations, complications such as bleeding and edema may occur. In severe cases, tracheotomy and other treatments may even be required. Therefore, there is a lack of a suction tube that can adjust the angle for better insertion into the trachea. Utility Model Content
