Description

Technical Field

[0001] The present invention relates to the field of medical supplies, in particular to a tracheal tube capable of performing airway surface anesthesia. Background Art

[0002] Clinically, endotracheal intubation during general anesthesia is almost always associated with varying degrees of intubation reaction, primarily manifesting as choking, increased heart rate, elevated blood pressure, and even acute cardiovascular and cerebrovascular events. To suppress this choking reaction, a throat spray assembly is currently used to spray a local anesthetic into the throat, which is then removed before intubation. This approach improves intubation reactions to some extent. However, the separate operation of the throat spray assembly and the intubation tube is cumbersome, and the dual procedures may exacerbate throat bleeding and swelling, leading to adverse consequences. Some also perform cricothyroidotomy to reduce intubation reactions, but cricothyroidotomy itself is an invasive procedure that can cause bleeding, severe choking, throat injury, and severe cardiovascular reactions.

[0003] Local anesthesia of the trachea before surgery is an effective way to reduce tracheal reactions. Traditional tracheal tubes cannot perform local anesthesia, and when used, anesthetics can easily leak to other locations, which affects the safety of other locations. For this reason, we have made improvements and proposed a tracheal tube that can perform airway surface anesthesia. Summary of the Invention
