Abstract
A laryngeal mask apparatus includes a mask portion, a breathing tube and a suction tube. The suction tube is adapted for connection to a suction-producing device. The suction tube further includes suction ports that suck fluids and secretions from the patient's hypopharyngeal region when suction is created within the interior of the suction tube. The breathing tube is adapted for connection to a ventilating system. Air flows through the breathing tube and into the mask portion. A capillary tube is positioned within the interior of the suction tube. When the mask portion is positioned within apatient's throat and suction is created within interior of the suction tube, the suction ports suck the fluids and secretions in the patient's hypopharyngeal region. At the same time, the suction tubeand capillary tube cooperate to provide a stream of air that decreases the direct suction forces on the mucosa of the patient's throat that are caused by the suction ports. The laryngeal mask apparatus includes a scope tube having an interior and an inner tube disposed within the interior of the scope tube. The inner tube is sized for receiving a gastric tube.
