Medical treatment simulation devices

A medical treatment simulation device for simulating performance of a medical procedure on a live subject, the device comprising:

• an overlay configured to be secured to and cover at least a portion of a body of the live subject;
• a simulated treatment structure provided on the overlay and configured to simulate a structure associated with the medical procedure;
• at least one detector coupled to the simulated treatment structure and configured to detect an input generated by an interaction with the simulated treatment structure;
• and
• at least one feedback device coupled to the overlay, the at least one feedback device configured to provide feedback based on the interaction detected by the at least one detector.
