Description

Technical Field

[0001] The utility model relates to the technical field of laryngeal masks, and more specifically to an antibacterial laryngeal mask airway device. Background Art

[0002] The laryngeal mask is a medical device used for airway management. It is an airway maintenance tool between a mask and an endotracheal tube. The laryngeal mask is designed to provide airway support and ventilation to patients without endotracheal intubation. The laryngeal mask is relatively easy to place and does not require the use of a laryngoscope. Therefore, it is easier for medical personnel who have no experience in endotracheal intubation to use the laryngeal mask. Compared with endotracheal intubation, the laryngeal mask causes less stimulation to the patient's throat and trachea, reducing the risk of injury. Since the laryngeal mask does not need to be inserted into the trachea through the vocal cords, patients are usually more tolerant and reduce the occurrence of throat pain and coughing.

[0003] In the existing technology, when the two tubes of the existing laryngeal mask ventilation tube are inserted into the patient's mouth during operation, the tubes may easily touch the sensitive area of ​​the patient's throat, causing instinctive stress reactions such as retching, causing discomfort to the patient. The existing laryngeal mask drainage cavity can be used to drain esophageal reflux materials when in use, and because the drainage cavity and the ventilation cavity are both arranged in the laryngeal inflation tube, it is easy for the esophageal reflux materials in the drainage cavity to flow into the ventilation cavity, affecting the ventilation effect.
