Background
The existing laryngeal mask adjusts the size of the cuff through inflation and air extraction of the inflatable balloon and the valve, so that the tightness of the laryngeal mask and the laryngeal cavity is ensured. In general anesthesia procedures for laryngeal masks, we typically impart muscle relief to facilitate the procedure and placement of the laryngeal mask.
The length of the conduit of the existing laryngeal mask and the bite block fixed on the conduit are designed according to the oropharynx physiological anatomical structure of European and American countries, and according to the design, after the laryngeal mask is placed in the oral cavity of a patient, the bite block just abuts against the incisor position of the patient, so that the laryngeal mask is better fixed. Because the European and American people have relatively high body type, the physiological radian of the oropharyngeal cavity and the depth from the incisors are different from those of the people in China to a certain extent, after the laryngeal mask model is selected according to the recommended weight, the position of the dental pad of the laryngeal mask is higher than the incisors of the patient because the dental pad is fixed on the catheter of the laryngeal mask and cannot be adjusted, so that the risk of shifting the laryngeal mask is increased.
