The Ferguson Frazier Suction 7Fr is a medical suction catheter used for removing fluids, such as mucus or secretions, from the respiratory or other bodily cavities. The "7Fr" refers to the French gauge size, indicating a catheter with a slightly larger diameter compared to the 6Fr version. This catheter is commonly used in procedures that require precise suction, such as airway clearance in both adult and pediatric patients.
