What are the description and function of aspirator?

An aspirator is a medical device used to remove fluids or debris from a patient's body, typically through suction. It is commonly employed in surgical procedures, wound care, and during the extraction of mucus or other secretions from the respiratory tract. The device operates by creating a negative pressure that draws the unwanted material into a collection container. Aspirators are essential for maintaining clear airways and ensuring a sterile environment during medical interventions.
