Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an oral cannula fixing device. Background Art

[0002] Oral intubation is a medical procedure, often used in situations where general anesthesia or respiratory support is required. This procedure involves inserting an endotracheal tube through the patient's mouth into the trachea to ensure a clear airway and allow for mechanical ventilation.

[0003] During oral intubation, the operator is usually required to use tape to insert the oral cannula into the patient's mouth and use the patient's own tooth bite force to occlude the oral cannula for positioning. However, this positioning method makes the tape very easy to fall off after long-term use, and some elderly edentulous patients are very likely to cause the oral cannula to fall off from the inside of the mouth during use. Therefore, we propose an oral cannula fixing device. Utility Model Content
