A LARYNGEAL MASK AIRWAY DEVICE

摘要

A laryngeal mask airway device for insertion into a patient to provide an airway passage to the patient's glottic opening. The device comprises an airway tube and a mask attached to the airway tube. The mask comprises a body and a peripheral cuff, which defines an outlet for gas. The mask is connected to the airway tube for gaseous communication between the tube and the mask. The airway tube comprises a relatively more rigid thermoplastic skeleton and at least one layer of a relatively more flexible thermoset material. A method of constructing such a device comprising a), providing a thermoplastic skeleton of an airway tube; and b). overmoulding a first layer of a relatively more flexible thermoset material onto the skeleton to form an airway tube is also covered.
