A removable bite block for endotracheal intubation

Abstract

This utility model discloses a movable bite block for endotracheal intubation, applied in the field of endotracheal intubation technology. This utility model uses a movable lever to move a connecting block, causing a limiting plate to move and disengage from the limiting groove, compressing a first spring. Then, a strap is passed through the connecting groove, and the lever is released to allow the first spring to rebound, causing the limiting plate to automatically reset. A fixing cone then secures the strap within the limiting groove, making it convenient, quick, and aesthetically pleasing. The catheter is inserted into the bite block body and contacts and compresses multiple sets of rollers, causing an arc-shaped plate to move a connecting rod. The movement of the connecting rod moves a guide block, and a second spring allows multiple sets of rollers within the arc-shaped plate to fix the catheter within the bite block body. Simultaneously, the rotating rollers allow for easy adjustment of the catheter.

Description

Technical Field

[0001] This utility model belongs to the field of endotracheal intubation technology, and specifically relates to a removable bite block for endotracheal intubation. Background Technology

[0002] Endotracheal intubation is a technique that involves inserting a specially designed endotracheal tube through the glottis into the trachea. This technique provides optimal conditions for airway patency, ventilation and oxygen supply, respiratory suction, and prevention of aspiration. Removable bite blocks can reduce damage to the patient's mouth and teeth during medical procedures such as endotracheal intubation.

[0003] Currently, Chinese utility model patent CN222605161U discloses a removable mouthguard and an endotracheal tube using the removable mouthguard, which relates to the field of endotracheal tube technology. The device fixes the mouthguard by passing one end of a strap through a connecting hole and connecting it to the corresponding ear plate, and passing the other end through another connecting hole and connecting it to the corresponding ear plate. When in use, the elasticity of the strap is used to wrap around the patient's head to fix the mouthguard. Because the connecting hole has a small diameter, medical staff need to use a workpiece to pass the strap through the ear plate, which is a rather cumbersome process. In addition, after the strap passes through the ear plate, it needs to be knotted to fix it, which affects the appearance. Furthermore, after the catheter and dental pad are fixed, it is not convenient to adjust the catheter. Therefore, this needs to be improved.

[0004] This utility model belongs to the field of endotracheal intubation technology, and specifically relates to a removable bite block for endotracheal intubation. Summary of the Invention
