Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are part of the present invention Examples, not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Referring to Figure 1, a sputum suction tube, the sputum suction tube includes a sputum suction tube body 2, the head end of the sputum suction tube body 2 is provided with an elbow 5 that is convenient to cooperate with the respiratory tract to suck sputum, and the tail end of the sputum suction tube body 2 There is a joint 1 for easy connection with the ventilator; the head end of the elbow 5 is provided with a sputum suction port, and the side of the head end of the elbow 5 is provided with bilateral holes or opposite perforations 4 for easy sputum suction. The 5-shaped head end of the elbow can reduce the pain of the patient during the intubation process and the damage of the respiratory mucosa during sputum suction. , smoothly sucked out; and the tension of the catheter is small, there is no pressure on the respiratory mucosa, and no internal injury will occur after a long time; the setting of the connector 1 facilitates the connection of the suction tube to the ventilator.

The angle formed between the elbow 5 and the sputum suction tube body 2 is 120°-150°; preferably, the angle formed between the elbow 5 and the sputum suction tube body 2 is 135° °; the head end of the elbow 5 is a smooth head end, and the length of the elbow 5 is 20cm-30cm; the length of the elbow 5 is 25cm. The smooth head end can reduce the pain of the patient during the intubation process and the damage to the respiratory mucosa during the suction process; the setting of the elbow 5 is convenient for better adapting to the physiological bending for suctioning.
