Syringe with a background for writing and reading index markings

摘要

A syringe includes a barrel having a cannula at one end and a plunger at its opposite end whereby fluid may be drawn into or expressed from the barrel by translatory movement of the plunger relative to the barrel. A white ink receptor coating is provided on the barrel at manufacture and on which coating writing may be applied by the medical practitioner using a common ordinary writing implement such as a ballpoint pen. By locating the ink receptor coating diametrically opposite the index markings on the syringe barrel and providing the coating in a white color, the index markings may be readily read against the contrasting white background to ascertain the quantity of fluid within the syringe barrel.
