| 摘要 |
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 an airway tube (10) opening into the interior space or lumen of a mask portion (12) whose periphery (14), which may be inflatable, is adapted to seal around the inlet (36) to the larynx (38), thus securing the patient's airway, permitting spontaneous or controlled ventilation and preventing inhalation of extraneous matter, means such as cross-bars (21) being provided to prevent obstruction by the epiglottis of the aperture (19) by which the airway tube (10) opens into the lumen of the mask. |
