Description

Technical Field

[0001] The utility model belongs to the field of medical devices, and particularly relates to an endotracheal tube. Background Art

[0002] Endotracheal intubation is a method of inserting a special endotracheal catheter through the oral cavity or nasal cavity and into the trachea or bronchus through the glottis, providing the best conditions for airway patency, ventilation and oxygen supply, airway suction, etc., and is widely used in the fields of clinical anesthesia, emergencies, intensive care treatment, etc. At the same time, it is also an important measure for rescuing patients with respiratory dysfunction.

[0003] Currently, the endotracheal tubes used clinically have a simple structure and single function. First, in clinical surgical anesthesia, anesthesiologists usually need to perform topical anesthesia on the patient's epiglottis and glottis before endotracheal intubation to reduce the adverse stimulation caused by endotracheal intubation to the patient. Currently, topical anesthesia requires the use of a separate nebulizer or catheter for operation, increasing the operation procedure and the patient's medical burden. Second, a separate bite block needs to be placed after endotracheal intubation to prevent the patient from having unexpected bites during anesthesia, especially during the awakening period. In addition, when a patient uses an endotracheal tube, especially in the intensive care field, the endotracheal tube needs to be retained for a long time. During this period, a large amount of secretions will accumulate in the trachea, around the trachea and in the oral cavity. These secretions need to be dealt with in time, otherwise it will cause or exacerbate oral and pulmonary infections, and even block the airway. In the existing technology, the secretions in the trachea and oral cavity can be aspirated repeatedly through a suction catheter, but it cannot meet the aspiration of the secretions near the oral end above the endotracheal tube cuff, and it is extremely easy to form sputum crusts, which are very likely to block the airway during the process of removing the endotracheal tube, resulting in asphyxia after extubation. Content of the Utility Model

[0004] In view of this, the utility model aims to propose an endotracheal tube that simultaneously has the functions of topical anesthesia of the epiglottis and glottis before endotracheal intubation, endotracheal drug administration, anti-bite, and aspiration above the cuff and above the oral glottis.
