Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to an oral cavity support type endotracheal tube fixer. Background technique [0002] Endotracheal intubation refers to the technique of inserting a special endotracheal tube into the trachea through the glottis, which is called endotracheal intubation. This technique can provide the best conditions for airway patency, ventilation and oxygen supply, respiratory tract suction and prevention of aspiration. . In order to prevent patients from being agitated due to intubation discomfort, and then causing accidental extubation or catheter fall-off, there are many ways to fix the tracheal intubation in clinical practice, and they can be selected according to the patient's condition. At present, most hospitals use adhesive tape Fixing the tracheal intubation has the advantages of soft touch, strong adhesion and not easy to fall off. However, when it is removed or replaced, there...

AI Technical Summary

Problems solved by technology

However, when it is removed or replaced, there will be adhesive tape marks on the surface of the endotracheal tube and the patient's skin. Due to the good water absorption of the adhesive tape, once it comes into contact with the patient's oral secretions, it will immediately pollute the adhesive tape and it is difficult to remove it from the skin. Ulceration occurs after the skin is frequently stretched, causing pain to the patient and susceptibility to wound infection, as well as increasing the workload of the medical staff; when the patient has a lot of secretions in the mouth, it is especially suitable for patients who cough up sputum and cannot clear it on their own and have no self-care ability , and an endotracheal tube is placed in the mouth, it is difficult to remove the secretions, making the patient prone to unplanned extubation and ventilator-associated pneumonia
