Abstract:
A laryngeal mask apparatus to ventilate a patient and also suck in fluids and secretions in the patient's hypopharyngeal region. The laryngeal mask apparatus has a mask, a flexible breathing tube in communication with the mask and a suction tube which has a plurality of suctioning ports that face the back of the patient's throat when the mask is inserted into the patient's throat. When suction is created within the suction tube, fluids and secretions in the patient's hypopharyngeal region are sucked into the plurality of suction ports. The laryngeal mask apparatus also has a flexible air capillary tube positioned within the interior of the suction tube to provide an air flow that decreases the direct suction forces on the mucosa of the patient's throat that are caused by the suction of the plurality of suction ports.
