Abstract
Abstract A barrel for a control syringe, including a substantially cylindrical body, a pair of horizontal flanges extending from the top of the cylindrical body, each of the horizontal flanges having an aperture therein adjacent the cylindrical body, and a pair of substantially horizontal flanges extending from the cylindrical body and located below the apertures in the horizontal flanges. The sides of the apertures are substantially the same shape as the sides of the substantially horizontal flanges. A single mold cavity and an integral core pin for forming the control syringe barrel are also disclosed.
