Einführungsvorrichtung

摘要

An introducer along which a laryngeal mask airway can be slid into position has an open, curved channel portion shaped to extend, in use, from a mouth of a patient to the region of the patient's pharynx. At its machine end, the introducer is bifurcated into two arms extending along opposite sides of the airway, the thickness of the arms being sufficient to protect the airway from damage by the patient's teeth. The arms are curved in an opposite sense from the curvature of the channel portion so that they extend over the upper lip of the patient. A curved bridge piece extends between the two arms and lies against the skin between the patient's nose and mouth.
