Description

Technical Field

[0001] The present application belongs to the field of medical devices, and specifically relates to a saliva suction device for patients with endotracheal intubation. Background Art

[0002] Endotracheal intubation is a commonly used way to establish an artificial airway during the resuscitation and respiratory support treatment of critically ill patients. It can provide effective conditions for medical operations such as unobstructed airway, auxiliary oxygen supply, and airway suction. During endotracheal intubation, the trachea is inserted into the trachea through the tracheal entrance in the mouth. During insertion, the mouth needs to be kept open all the time. Due to the long-term open mouth, a large amount of saliva is secreted, which is prone to choking and coughing, causing a certain risk to life. At present, two measures are often used to absorb the saliva of patients with endotracheal intubation. One is to use a cotton swab to absorb it, but it is not easy to operate and the absorption effect is poor; the second is to insert a new saliva tube into the patient's mouth, which is specifically used to absorb saliva, but some saliva tubes do not have special fixing devices and may fall off from the patient's mouth.
