Technical Field
[0001] The utility model relates to the technical field of endotracheal cannula, in particular to an anti-falling endotracheal cannula. Background Art
[0002] Endotracheal intubation is a method of inserting a special endotracheal tube into the trachea or bronchus through the oral cavity or nasal cavity and the glottis, which provides the best conditions for airway patency, ventilation and oxygen supply, and airway suction, and is an important measure to rescue patients with respiratory dysfunction. However, the endotracheal tube is relatively smooth and there is a risk of falling off or slipping. Therefore, we propose an anti-falling endotracheal tube. Utility Model Content
[0003] In view of the above technical problems, the utility model provides an anti-falling endotracheal cannula, which is characterized by comprising an endotracheal cannula, a cannula head, and an anti-falling structure, wherein the end of the endotracheal cannula is connected to the cannula head, the cannula head is connected to a limiting plate, and the cannula head is clamped by the anti-falling structure;
[0004] The anti-falling structure includes a positioning block A, a positioning block B, a sliding rod, a screw, a motor, a fixing plate, a cushion block, a connecting belt, and a connecting ring. The two ends of the sliding rod are respectively fixed with a positioning block B and a fixing plate. The sliding rod is provided with a positioning block A, the positioning block B is provided with a motor, the motor is connected with a screw, and the screw passes through the positioning block A and the positioning block B. The fixing plate is connected with a cushion block, the positioning block B is connected with a connecting belt, and the connecting belt is connected with a connecting ring.
[0005] The connecting belt and the connecting ring are both elastic.
[0006] Beneficial effects of the utility model:
[0007] The utility model rotates the screw rod together with the motor output end, and the positioning block A moves along the screw rod and the sliding rod toward the positioning block A until the positioning block A and the positioning block B can lightly clamp the intubation head, and the limiting piece on the intubation head is clamped on the positioning block A and the positioning block B, so that the tracheal intubation tube is clamped and clamped, thereby solving the hidden danger of the tracheal intubation tube falling off.
[0008] After the tracheal tube is inserted into the trachea of the patient, the positioning block B is stuck at the philtrum of the patient, the positioning block A is stuck at the chin, the bottom of the chin of the patient is gently stuck by the pad, and then the connecting ring is hung on the patient's ear. The utility model allows doctors to choose a more suitable wearing method according to the patient's condition by clamping the anti-falling structure on the patient's chin, the bottom of the chin, and hanging on the ear.
