A flexible tube designed to be inserted through the mouth, artificial airway, tracheostomy tube, and/or nostrils, for periodic aspiration of liquids and/or semi-solids from a patient's airway (e.g., pharynx, trachea, bronchi, nasal cavity) as part of a suction system; it is not intended to inflate the lungs. It is typically made of polymer with a smooth and rounded distal-tip, often including end and side holes and a finger-controlled valve to regulate suction. This is a single-use device.
