Zusammenfassung: | The utility model belongs to the technical field of the human technique of ventilating of breathing and specifically relates to indicate a multi-functional laryngeal mask subassembly, including cover bag body and set up in the laryngeal mask gasbag of the entering end of cover bag body, the link of cover bag body is connected with handheld handle, the air duct in the through-hole of placing cover bag body in can in still, and the outer wall that the entering of this air duct was held inlays and is equipped with the air duct gasbag, and the air duct gasbag is connected with the first air bleeder that fills through first built-in tubule, and first built-in tubule is buried underground in the pipe wall of air duct, the outer wall of air duct is provided with the sealing device who guarantees gas tightness between air duct and the cover bag body. Because sealing device sets up the gas tightness in the time of can effectively guaranteeing to ventilate, can make the air duct can slide again and the protection lung weighs wounded, lets laryngeal mask function and the interior pipe of the trachea function interconversion fast immediately of ventilating of ventilating. |
