Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to an adjustable endotracheal tube fixing teeth pad. Background Art

[0002] The dental pad is an indispensable tool in general anesthesia for endotracheal intubation. Its main function is to assist in the fixation of the endotracheal tube and prevent the patient's teeth from damaging the endotracheal tube. During the operation, poor ventilation due to improper tube position often occurs. In particular, double-lumen bronchial tubes are required in thoracic surgery. After intubation, it is necessary to readjust the position of the fixed tube due to factors such as changes in the patient's body position. At present, the most commonly used method of dental pads in clinical practice is to place the dental pad on the front teeth and fix it side by side with the endotracheal tube after the endotracheal tube is in place. The fixing method is usually wrapped with tape or bandages. Whenever the position of the catheter needs to be adjusted, the tape or bandage must be loosened and fixed, which consumes too much time and energy. At the same time, when patients with general anesthesia and intubation undergo esophageal ultrasound, gastroscopy and other operations, traditional dental pads occupy the space next to the catheter, which is not conducive to related operations. Therefore, dental pads are often not placed during such examinations, causing certain risks. Therefore, a dental pad that can achieve stable fixation of the catheter, conveniently adjust and change the position of the catheter, and does not occupy extra space in the oral cavity is very necessary.
