Description

Tracheal tube fixator

Technical Field

The utility model relates to the technical field of medical auxiliary equipment, in particular to a tracheal tube fixer.

Background Art

In clinical treatment, medical staff insert the endotracheal tube into the patient's trachea through the mouth to assist the patient's breathing, relieve airway obstruction, and absorb tracheal secretions. After endotracheal intubation, medical staff need to properly fix the endotracheal tube to prevent the tube from falling out when the patient's body position changes or the body moves violently. Generally speaking, dental pads are used clinically to assist in the fixation of the endotracheal tube. The traditional method is to place the endotracheal tube in the middle of the mouth, place the dental pad between the upper and lower incisors, and use medical tape to cross-fix the endotracheal tube and the dental pad, and use an inch-long tape to tie a knot around the back of the neck to help fix the tube position. During clinical operations, it was found that many middle-aged and elderly patients had missing teeth or loose incisors. At this time, the use of dental pads poses potential risks: first, when patients with loose incisors use dental pads, the loose incisors may fall out faster; second, the gums of edentulous patients are exposed due to tooth loss, and conventional fixation methods can cause wear on the delicate gums of the patients, leading to bleeding or even ulcers; third, edentulous patients often have depressions on their lips, and the endotracheal tube cannot be fixed well with dental pads. Even if no dental pads are used and the tube is fixed with tape alone, the position of the tube is very easy to change, and the patient's airway safety cannot be guaranteed during general anesthesia.

Utility Model Content

The utility model aims to provide a tracheal tube fixer to solve the problem that some patients cannot fix the tracheal tube by biting the tooth pad.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical solutions: a tracheal tube fixer, comprising a base and a fixing belt, a catheter through hole penetrating both sides is arranged in the middle of the base, a sputum suction hole penetrating both sides is arranged on the side of the catheter through hole, a fixing block for connecting the catheter is arranged at the position of the catheter through hole on the outside of the base, a fixing hole penetrating both sides is arranged on the fixing block, the fixing hole and the catheter through hole are aligned, a dental pad is detachably arranged at the position of the catheter through hole on the inside of the base, and fixing belts are connected to both left and right ends of the base.

A further technical solution is that a compression plate is arranged in the fixing hole, one side of the compression plate is connected to the hole wall of the fixing hole through a spring, and the other side of the compression plate cooperates with the hole wall of the fixing hole to form a fixing channel for fixing the catheter.

A further technical solution is that a sliding hole connected to the outer wall of the fixed block is provided on the hole wall of the fixing hole away from the spring, and a support rod is slidably provided in the sliding hole.
