suction catheter

A suction catheter is a medical tube used to remove excess fluids, mucus, or secretions from a person's airway or throat. It helps keep the airway clear, especially when someone is unable to cough or clear it on their own, such as during surgery, illness, or in critical care. The catheter is inserted into the mouth, nose, or trachea and connected to a suctioning device that gently pulls out the unwanted substances. This process ensures the person can breathe more easily and reduces the risk of choking or infection.
