ABSTRACT:
An apparatus for optically determining and electronically recording the dose of an agent delivered with a syringe. The syringe has a barrel for holding the agent and a plunger movably positioned in the barrel for expelling the agent. The barrel has an injection end through which the agent is expelled. The plunger has a variable color marking whose color varies along the direction of the longitudinal axis of the plunger. The color of the variable color marking at a predetermined distance from the injection end of the barrel varies in dependence upon the position of the plunger in the barrel. The apparatus includes an optical measuring instrument for measuring the color of the variable color marking at the predetermined distance from the injection end. A microprocessor determines the dose from the measured color. A recorder, such as a digital memory unit, electronically records the determined dose.
