Abstract:
A system for simulating sounds arising from human organs for use in an anatomical simulation device comprising:a human patient mannequin torso;a portable simulated stethoscope that includes a bell end piece;a plurality of sensors forming a grid mounted in predetermined strategic locations within said human patient mannequin torso;a computer including a sound board connected to said plurality of sensors;a radio frequency transmitter including an antenna for transmitting RF signals connected to said computer;said stethoscope including a RF receiver positioned in a location remote to said bell end piece for receiving RF signals sent by said radio frequency transmitter;said sound board further having a sound card which generates RF signals from prerecorded sound files;means mounted in said stethoscope attached to said receiver for generating audio sounds from the RF signals received by said receiver; andeach of said sensors connected to said computer representing a different location with respect to said human patient mannequin torso and said sound board including a plurality of different pre-recorded organ sounds which are correlated with the location of each of said sensors so that said sensor can detect the presence of said stethoscope bell end piece and said computer provides the appropriate RF signals representing the human organ sound from that location to be received by said stethoscope.
