Contrast media injectors designed to inject the contrast media through a small catheter into the vascular system for angiographic studies. These devices typically consist of automated electromechanical injectors with syringes that may be either reusable, disposable, or both; pneumatic mechanism are less frequently used. Angiographic contrast media injectors are capable of delivering with the pressure, flow range, and volume required for angiographic studies, some injectors can synchronize the delivery with the electrocardiographic cycle and/or the x-ray generator. They are used in procedures to examine the coronary and renal arteries, the great vessels and the vasculature of the heart, brain, abdominal organs, and extremities.
