A suction device is a tool used to remove fluids or debris from a specific area. It works by creating a vacuum that pulls substances into a container or tube. These devices are commonly used in medical settings to clear airways, in construction to remove dust, and in households for cleaning purposes. There are various types of suction devices, including handheld models and larger machines. In medicine, a suction catheter is often used to help patients breathe by clearing mucus. In everyday life, a vacuum cleaner serves a similar purpose by sucking up dirt and debris from floors and carpets.
