Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a quick fixing device for an endotracheal cannula. Background Art

[0002] In medical practice, endotracheal intubation is one of the important means of treating critically ill patients. It can effectively establish an artificial airway and ensure the patient's airway is unobstructed. However, fixation and care after endotracheal intubation is a very challenging task. Traditionally, medical staff usually use gauze bandages to fix the endotracheal tube. Although this method is simple and easy, it has many shortcomings.

[0003] First, the fixation of gauze bandages requires frequent adjustment to ensure their tightness and stability, which not only increases the workload of medical staff, but may also cause the endotracheal tube to shift or fall out due to improper operation, endangering the patient's life. Secondly, gauze bandages are prone to breed bacteria after long-term use, increasing the risk of infection, which is particularly dangerous for patients with low immunity. In addition, the replacement process of gauze bandages is also relatively cumbersome, requiring untying and re-tying, which is not only time-consuming and labor-intensive, but may also cause unnecessary pain and irritation to patients.
