Leubecker Attorney, Agent, or Firm Needle &Rosenberg, P.C. 57 ABSTRACT A method and an apparatus for quantifying the amount of fluid administered to a patient Simulator during Simulated medical Surgery. A fluid administered to a manikin and delivered to a reservoir associated with the manikin. The quantity of fluid administered is determined based on the change of weight of the reservoir. A simulated response to the administered fluid can be computed, based on the determined quantity of fluid administered. 23 Claims, 7 Drawing Sheets IV MANIFOLD 4O7 SYRINGE 40O OPTICAL SWITCH COMPUTER SWITCH4O6
