Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a cannula fixation structure that can reduce damage to the patient's skin and mucous membranes. Background Technology

[0002] Endotracheal intubation involves inserting an endotracheal tube through the mouth or nose into the patient's trachea to assist breathing, relieve airway obstruction, and suction tracheal secretions. It is commonly used for patients under general anesthesia, those with airway obstruction, or those with excessive airway secretions that cannot be cleared spontaneously.

[0003] In existing technologies, when fixing endotracheal tubes in the oral cavity, the traditional method is to use tape to fix the endotracheal tube, and then insert an instrument such as a syringe into the patient's mouth to prevent the patient from biting the endotracheal tube. The syringe is also fixed with tape. There are also instruments with a dental crown that have an endotracheal tube channel and can be inserted into the teeth, and are fixed with straps. There are also instruments that use an air bag in the patient's mouth in conjunction with straps for placement and fixation.

[0004] The method of securing endotracheal tubes with tape is prone to loosening due to secretions or sweat. Long-term adhesion can easily lead to pressure sores, and tearing it off may also damage the patient's skin. Furthermore, the base of the brace structure and airbag structure can easily cause damage to the oral mucosa and gums of patients with severe tooth loss or even no teeth (mostly elderly patients), leading to patient dissatisfaction.

[0005] Therefore, this invention provides a cannula fixation structure that can reduce damage to the patient's skin and mucous membranes, in order to solve at least one of the aforementioned problems. Utility Model Content
