Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a novel oral endotracheal tube fixer. Background Art

[0002] Tracheal intubation is an important measure to rescue critically ill patients and maintain airway patency. It is also the only way to quickly establish an artificial airway to achieve ventilator-assisted ventilation to correct respiratory failure.

[0003] At present, medical staff use tape to fix the disposable dental pad to the endotracheal tube. This disposable dental pad is made of hard plastic and is mainly used to prevent the patient's teeth from biting the tube to protect the endotracheal tube. Then, some tape is used to fix the tube to the patient's cheek. In order to prevent accidental extubation, a band can be used to tie the endotracheal tube and the dental pad around the patient's neck to fix it. The indwelling time of oral endotracheal tube is usually 3 days to 1 week. If the condition is not relieved and respiratory failure is not corrected, the intubation time can be up to 3 weeks or even longer.

[0004] Nowadays, hospitals often use dental pads as fixators for oral endotracheal intubation tubes, as follows Figure 4 As shown, the part of the dental pad extending into the oral cavity is made of a harder plastic material. If the dental pad is in contact with the patient's oral cavity for a long time, it is very easy to cause damage to the patient's oral cavity. Therefore, a new oral endotracheal tube fixator is proposed to optimize and solve the above problem. Utility Model Content

[0005] The purpose of the utility model is to provide a novel oral endotracheal tube fixer to solve the problems raised in the above background technology.

The opposite sides of the first fixing seat 2 and the second fixing seat 3 are arranged in contact with each other. The first fixing seat 2 is fixedly connected to the outside of the first fixing seat 2 with the first connecting rod 4. One end of the first connecting rod 4 is hinged to the outside of the second fixing seat 3 through a hinge seat. The first fixing seat 2 is fixedly connected to the outside of the second connecting rod 5.
