Suction devices are tools designed to remove fluids or debris from a specific area. They work by creating a vacuum that pulls substances into a container or tube. Commonly used in medical settings, these devices help clear airways, remove excess fluids during surgeries, or assist in wound care. In addition to medical applications, suction devices are also found in household items like vacuum cleaners and plungers. These devices utilize similar principles to clean surfaces or unclog drains by creating a difference in air pressure. Overall, suction devices play a vital role in both health and everyday life.
