Abstract

A drug recognition system for patient simulators is provided for use in training in anesthesiology, operating rooms, and emergency rooms. In a patient simulator mannequin, simulated intravenous drugs are administered by syringe. Each syringe used on a multiple syringe manifold contains a simulated drug fluid and an integrated circuit preprogrammed with a drug type and concentration. A flow sensor provides the amount of simulated drug administered. A computer senses the drug type and concentration from the integrated circuit attached to the syringe, and measures the amount administered from the flow sensor. The drug type, concentration, and amount administered is used by the computer, along with other measured parameters, body and drug models, and trainer input, to cause the simulator mannequin to react in the proper or desired manner. In an alternate embodiment, the system can be used to record the type, concentration, and amount of actual drugs administered to a real patient. In an alternate embodiment, the system can be used in conjunction with a device to automatically administer drugs to a real patient under the control of a computer using adaptive body and drug models initially under the control of a physician.
