Definition : Instruments designed to inject fluids using an automated mechanism. Most of these instruments are automated injectors powered using either electric, electronic (typically battery powered), or pneumatic mechanisms. Some injectors are manually, mechanically operated. Injectors are used mainly to introduce bolus injections of viscous fluids (e.g., contrast media, medications, mold casting materials, vocal cord augmentation material) into the subcutaneous tissues, arteries, veins, or lymphatic vessels, or body cavities such as the ear and larynx; some injectors are used in laboratory procedures (e.g., chromatography systems).
