Abstract

It is intended to provide a laryngeal mask comprising: an inflation cuff having an inflatable hollow tubular part, a back plate which is air-tightly bonded to the hollow tubular part so as to cover one end of the inside diameter side space, and a cuff inside space which is surrounded by the inside diameter curved face and the inside face of the back plate and has an opening in the side opposite to the back plate; an airway tube which has one end opening toward the cuff inside space and the other end opening toward the space outside the oral cavity; and a gastric tube insertion guide wherein a guide face, which aims at inserting a gastric tube from the mouth until its front edge reaches the stomach or esophagus region in the state of inserting the inflation cuff into the pharyngeal region, is continuously or intermittently provided from the inflation cuff to the outside of the oral cavity.

Description

technical field [0001] The present invention relates to a laryngeal mask (Laryngeal Mask Airway: LMA) installed on the larynx for ensuring ventilation and breathing of the lungs Background technique [0002] In order to ensure lung ventilation and respiration, endotracheal intubation has been used for a long time, but this type of endotracheal intubation is difficult to operate reliably and safely in emergency situations, with the risk of intubation failure, or giving Risk of injury from the trachea. Therefore, a laryngeal mask in which an inflatable cuff is attached to the patient's larynx to secure an airway is now widely used instead of the conventional endotracheal tube. [0003] The laryngeal mask includes a flexible airway tube and an inflatable inflation cuff installed at the front end of the airway tube. In addition, the method of use is to insert the inflatable cuff in the contracted state from the patient's mouth into the throat, and then supply gas to the inside...
