Description

Technical Field

[0001] This invention belongs to the field of anesthesiology equipment technology, and particularly relates to a fixation device for anesthesiology endotracheal tubes and its usage method. Background Technology

[0002] An endotracheal tube in anesthesiology is an artificial airway device inserted into the trachea through the upper respiratory tract to ensure a patent airway. Widely used in clinical anesthesia, it is one of the most reliable methods for establishing an artificial airway. The endotracheal tube plays a crucial role in clinical anesthesia and critical care. Its core function is to establish a safe artificial airway, ensuring patient ventilation and oxygenation, while preventing aspiration and complications. During general anesthesia, anesthetic drugs suppress the patient's spontaneous breathing, leading to respiratory muscle relaxation or even respiratory arrest. By connecting to an anesthesia machine or ventilator, the endotracheal tube can forcefully deliver oxygen and expel carbon dioxide, ensuring normal gas exchange during surgery.

[0003] The problem with existing technology is that when the endotracheal tube is not fixed, the patient's head movement, surgical operation, or movement of the anesthesia machine tubing may cause the tube to change position in the trachea, which may repeatedly rub against the tracheal mucosa, leading to mucosal damage, bleeding, or even tracheal ulcers or granulation tissue hyperplasia. Summary of the Invention

[0004] To address the problems existing in the prior art, this invention provides a device for fixing endotracheal tubes in anesthesiology and a method for using it. It has the advantage of fixing the endotracheal tube and solves the problem that when the endotracheal tube is not fixed, patient head movements, surgical procedures, or movement of the anesthesia machine tubing may cause the tube to change position in the trachea, resulting in repeated friction against the tracheal mucosa, leading to mucosal damage, bleeding, or even tracheal ulcers or granulation tissue hyperplasia.

Then, the arc block 904 positions and clamps the top of the guide tube 3 inside the sleeve 2, thereby ensuring the stability of the upper part of the sleeve inside the sleeve 2. Working principle of the invention: In use, place the placement tray 1 and sleeve 2 at the patient's mouth, then insert the sleeve 2 into the patient's mouth. At this time, the placement tray 1 can be positioned by the head restraint rope 18, thus placing it on the patient's head. Then, the catheter 3 can be inserted into the sleeve 2 and extended into the patient's mouth. Then, the positioning member 604 can be tightened. At this time, the clamping plate 605 and the sliding plate 603 are pressed together to position it. Then, the vertical block 601 can be positioned by the positioning of the sliding plate 603. Then, the catheter 3 inside the sleeve 2 can be clamped by the restraint rod 602 after contacting it, thus completing the positioning of the catheter 3 inside the sleeve 2. At this time, the pulling rod 902 can be pulled. When the pulling rod 902 is released from the restraint of the clamping connector 13, it can drive the connecting column 903 to pass through the positioning block 7.
