Abstract

This utility model relates to a dental splint for endotracheal intubation, comprising an upper dental splint, a lower dental splint, a suction catheter, and a clamp for securing the endotracheal tube. The upper and lower dental splints are respectively installed on both sides of the suction catheter, and the clamp is located in front of the upper and lower dental splints and connected to the suction catheter. This dental splint for endotracheal intubation is equipped with a suction catheter, which not only absorbs secretions and improves patient comfort, but also allows for the injection of water or medication, facilitating treatment. The teeth are embedded in the upper and lower dental splints respectively, preventing them from contacting the endotracheal tube and making it less likely to be bitten off. The clamp secures the endotracheal tube, preventing displacement and dislodgement.

Description

Trachea cannula tooth pad

Technical Field

The utility model relates to medical equipment, in particular to an endotracheal intubation bite block.

Background

In the practice of medical first aid and intensive care, endotracheal intubation is a vital life support measure that ensures unobstructed patient airway by establishing an artificial airway, providing a direct path for oxygen supply and drug administration. However, after the endotracheal tube is completed, a common problem is the stability of the endotracheal tube in the patient's mouth. Because the endotracheal tube needs to remain in the patient's mouth for a long time, the patient may be accidentally bitten by the chewing or biting action under unconscious or conscious vague conditions. In this case, the patient may encounter an emergency situation in which the patient cannot breathe or is severely blocked, which not only hinders the normal treatment process, but also greatly delays the recovery speed of the patient, and the patient is more seriously threatened, even the life safety of the patient may be directly threatened, and the fatal risks such as asphyxia are caused.

Aiming at the clinical challenge, chinese patent CN202069975U provides an innovative solution, namely an anti-bite adult tracheal catheter. The design provides a smart bite resistant identification layer on the tracheal tube body, particularly at a critical location about 22 to 24 cm from the distal end of the tube. This design aims to enhance the resistance to biting forces in the area by specific materials or structures, reducing the risk of being bitten. Furthermore, in order to improve the comfort of the patient and effectively prevent biting, the exterior of the anti-biting recognition layer is covered with a soft tooth protection layer. The protective layer has the characteristics of mildness and toughness, and effectively avoids the closing of the tracheal catheter caused by occlusion, thereby ensuring the smooth breathing of a patient and reducing a series of complications caused by unsmooth breathing.

Although the above patent has achieved remarkable results in preventing the tracheal catheter from being bitten, in practical application, medical staff have encountered a new problem that the insertion of the conventional sputum aspirator tube becomes extremely difficult due to the addition of the soft tooth protection layer outside the tracheal catheter. Sputum aspiration is an important care step in the removal of oral and respiratory secretions from a patient and is critical to maintaining respiratory cleanliness and preventing pulmonary infection. Therefore, this design limitation is disadvantageous in that it effectively manages secretions in the patient's mouth in time, possibly increasing the risk of respiratory tract infections, affecting the therapeutic effect.
