ABSTRACT:
An apparatus for determining and recording a 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 plunger includes a magnetically responsive element, such as an iron core. The apparatus has a receptacle for receiving the syringe for dose measurement. An inductive element is positioned coaxially to the receptacle to produce a magnetic field. When the syringe is placed in the receptacle, the intensity of the magnetic field varies in dependence upon the position of the plunger in the barrel. The magnetic field induces a voltage in a conducting loop. A voltage meter is connected to the conducting loop to measure the induced voltage. A microprocessor is connected to the voltage meter to calculate the dose from the measurement of the induced voltage. A recorder, such as a digital memory unit, records the dose.
