Vascular access training simulator system and transparent anatomical model
A vascular access training simulator system for training intravascular insertion of a medical device is disclosed. The vascular access training simulator system includes an anatomical training model having clinically relevant ultrasonic properties representative of ultrasonic properties of a human body site for ultrasound imaging. The training model includes a transparent housing, a transparent simulated tissue, at least one simulated blood vessel suspended in the tissue, and a layer of simulated skin covering the housing and the tissue. A first imaging device is records a first video showing a view of an insertion site outside of the simulated skin. A second imaging device records a second video showing the simulated blood vessel through the transparent simulated tissue. A third imaging device is shows an ultrasound view of the simulated blood vessel and the simulated tissue. A monitor displays a composite view of all three videos simultaneously on a single screen.
