A Suction Machine uses suction to remove excess mucus and saliva that can accumulate in your mouth when your ability to swallow is impaired. It will help you breathe more easily, choke less when eating and drinking, and generally feel more comfortable. It creates a vacuum which draws out mucus and gasses from a patients airway or body cavity during surgery. Often used in the nose and throat to help clear airways. It uses a long thin flexible plastic tube known as a catheter to vacuum out the secretions blocking the airways. The Suction Machine is very efficient and useful.
