Description

Technical Field

[0001] The utility model relates to the technical field of endotracheal tube fixers, in particular to an endotracheal tube fixer for respiratory medicine. Background Art

[0002] Endotracheal intubation is a method of inserting a special endotracheal tube into the trachea or bronchus through the oral or nasal cavity and the glottis, providing the best conditions for airway patency, ventilation and oxygen supply, and airway suction. It is an important measure to rescue patients with respiratory dysfunction.

[0003] After searching, it was found that the utility model with the publication number CN217162814U discloses a tracheal tube fixer used in respiratory medicine, including a fixing plate and a binding rope for fixing the fixing plate to the face, the fixing plate includes a sleeve tube, a ratchet member and a clamping strip, a cylindrical hole is provided in the axial middle of the sleeve tube, and the cylindrical hole extends to the back of the fixing plate; the ratchet member is fixed to the side of the sleeve tube, and the clamping strip is rotatably fixed on the ratchet member; since the clamping strip is fixed to the ratchet member, and the ratchet member can only rotate in a single direction, when the clamping strip is used to fix the cannula, the loosening of the cannula can be effectively avoided, and when the size and diameter of the clamped cannula need to be adjusted, it is only necessary to rotate the ratchet member to the dot, insert the cannula into the sleeve tube, and then push the clamping strip to clamp the cannula, which can effectively and conveniently fix the cannula, and can adapt to a variety of cannulae of different sizes, and at the same time use the sponge pad to fit the patient's face to avoid pressure sores on the patient's face caused by long-term wearing;

[0004] Although the above patent can fix the endotracheal tube, there are still some shortcomings: some patients close their mouths in an unconscious state, and their teeth bite the endotracheal tube, affecting ventilation and nourishment. In severe cases, the endotracheal tube may be damaged, which may easily lead to danger. Utility Model Content
