An artificial airway device, for use in place of an endotracheal tube to facilitate lung ventilation in an unconscious patient, is in the form of a laryngeal mask comprising a tube opening into the interior of a mask portion whose periphery, which may be inflatable, is adapted to seal around the inlet to the larynx, thus securing the patient's airway, permitting spontaneous or controlled ventilation and preventing inhalation of extraneous matter. |
