ABSTRACT:
The invention provides a model for simulating inguinal hernias including a frame and a plurality of sheets supported by the frame in overlapping relation to one another to create an anatomically accurate simulation of a portion of a patient's abdomen. Each of the sheets includes openings defined therethrough. A pump is interconnected to and in flow communication with at least one conduit that is supported by the frame so that an open end of the conduit is positioned adjacent to the openings. At least one balloon is disposed in sealed flow communication with the at least one conduit and positioned through the openings so that when the pump is actuated, fluid is urged through the at least one conduit and into the at least one balloon thereby inflating the balloon so as to simulate a hernia sac. Three balloons are utilized to demonstrate an indirect inguinal hernia, a direct inguinal hernia, and a femoral hernia. Anatomically correct overlays may also be placed in overlapping relation to the front and back of the frame so as to show a patient the relative placement of other anatomical structures relative to the position of the hernia.
