Description

Anesthesia atomizing device

Technical Field

The utility model relates to the field of anesthesia apparatuses, in particular to an anesthesia atomization device.

Background

Tracheal intubation is a fundamental operation of respiratory tract management during general anesthesia. However, for patients with difficult airways, the endotracheal intubation after anesthesia induction is challenging, and severe cases may occur in tragedy where ventilation/endotracheal intubation is impossible, or even dead. Therefore, the awake tracheal cannula which keeps spontaneous breathing is recommended to be the first choice for patients with high risk of combining difficult airways by the airway management guidelines at home and abroad. Adequate anesthesia of the throat and tracheal mucosal surfaces is a precondition for a conscious tracheal cannula. For critical patients needing tracheal intubation ventilation support in critical conditions, in order to reduce stimulation of the tracheal intubation, the occurrence of severe cardiovascular and cerebrovascular complications caused by circulatory fluctuation caused by the tracheal intubation can be greatly reduced due to sufficient mucosa surface anesthesia. The key to surface anesthesia is the delivery of the atomized state of the local anesthetic drug. The anesthetic drug atomizer of this design can fully atomize local anesthetic drug, makes atomized drug particles inhale along with the air current to produce reliable surface anesthesia effect.
