A concept for a sensorized medical tray in conjunction with real-time visual cues to aid medical residents in learning the steps of complicated tray-based medical procedures, such as central venous catheterization, was designed and tested as a first iteration. This paper outlines the selection of an LED screen to illuminate various medical devices and the testing of simple magnetic reed switches to use as sensors to track the movement of various medical tools from a tray. While this concept was designed around central venous catheterization, this work is translatable to any medical procedure using a pre-packaged plastic tray.
