The laryngeal mask is a clinically commonly used upper airway supraglottic ventilation device at present, has the effects of convenient placement and effective artificial auxiliary ventilation without being placed in a trachea, and has obviously smaller stimulation to a patient relative to a trachea cannula. However, the laryngeal mask has poor position fixing effect relative to the endotracheal intubation, and the laryngeal mask is sometimes driven to shift by the movement of the body position during operation, so that the air outlet end of the laryngeal mask moves and leaves the supraglottic region, and effective ventilation sometimes cannot be ensured.

In order to improve the accuracy of laryngeal mask placement, the clinical application of visual laryngeal masks is also emerging at present, in order to monitor and maintain the laryngeal mask in an accurate target position.

To ensure effective artificial assisted mechanical ventilation, a closed ventilation loop is provided without air leakage. The opening of the air outlet end of the laryngeal mask used clinically at present is obliquely facing to the glottic direction of the chest wall side, the air bag of the device is tightly attached to the periphery of the glottic and is obliquely arranged downwards and backwards, the air bag is formed by separating the glottic from the esophagus and the nasopharynx cavity and the oropharyngeal cavity above the pharynx part from the front upper part to the rear lower part, so that a closed ventilation loop is formed. By means of the multifunctional four-way connector, examination and treatment of the transesophageal endoscope and the like can be conveniently carried out without affecting normal ventilation.

At present, a similar glottic ventilation device which is opposite to the opening direction of the existing laryngeal mask is not available, an air bag expands and inflates obliquely upwards towards the direction of a rear hole of a nose, the glottic ventilation device is a high-position laryngeal mask, and a miniature camera is arranged on the inner wall of the air outlet end, so that the visual high-position laryngeal mask is formed.

The utility model patent of application number CN201420280402.7, a novel digestive tract endoscope diagnosis laryngeal mask, which is characterized in that a gastroscope channel and a ventilation channel are arranged in parallel, so that the whole tube diameter is obviously oversized, and certain difficulty is caused during placement; the lens channel and the lens end are designed at random, so that the lens can not be guaranteed to be opposite to the glottis after the laryngeal mask is placed, and the complexity of use is increased unless a bronchoscope is used.
