The laryngeal mask, a supraglottic airway management device, is an airway tool that is placed in front of the mask and the endotracheal tube. The front end of the ventilation tube is connected with a flat long sleeve made of silicon rubber or other soft materials, and the size of the flat long sleeve can just cover the larynx, so the ventilation tube is called as a laryngeal mask ventilation tube. The existing laryngeal mask is divided into an inflatable laryngeal mask and an inflation-free laryngeal mask, and the existing laryngeal mask has certain advantages and disadvantages:
1) because the prior inflatable laryngeal mask and the inflation-free laryngeal mask are two types of laryngeal masks which are independently used, the laryngeal mask cannot be used universally, has high processing cost and has certain selection limitation on clinic.
2) The inflation-free laryngeal mask is relatively simple and convenient to operate, the intubation tube is implanted quickly, the laryngeal mask can be used in the field of first aid, the laryngeal mask is free of air bags, mucous membrane damage caused by air bag pressure does not exist, different shapes of pharyngeal portions cannot be coped with, air leakage and displacement phenomena can occur, and the general inflation-free laryngeal mask intubation tube is easy to bend, twist, turn over and displace;
3) the inflatable laryngeal mask has the advantages that the balloon body is made to fit the shape of the pharynx by the inflating function of the inflatable laryngeal mask, the occurrence rate of air leakage and displacement is reduced, but the balloon body is large in size due to the fact that the outline of the inflatable laryngeal mask balloon body corresponds to the normal surrounding tissue structure of the throat, the balloon body cannot be inserted rapidly in the emergency process, and rescue time is affected;
4) in clinic, the risk of air leakage and backflow aspiration can occur when the laryngeal mask is displaced, the air leakage is a dangerous phenomenon sometimes, and particularly, when tools such as an electrotome and the like occur in the operation process, the combustion event can occur due to the air leakage, so that the laryngeal mask is very dangerous. Backflow aspiration may cause symptoms such as airway obstruction or aspiration pneumonia, which is a high risk.
