The Cogswell surgical aspirator is used for precision suction in the oral cavity to remove blood, saliva, and fragments of tissue and bone. The Cogswell aspirator is designed as a one-piece suction tube with a finger hole. The hole is located at the concave area midway along the tube. The intensity of the suction is increased when a finger covers the hole. The aspirator has a 2.3mm diameter opening and is made of surgical steel.
