Claim Text:
1. A stethoscopy training system comprising: a simulated stethoscope being provided with a sound acquisition unit, a tube and ear pipes; a location sensing means for sensing a location of the sound acquisition unit; a biological sound database; and a biological sound reproducing means, wherein when a trainee asks a simulated patient about his or her condition and auscultates the simulated patient by placing the sound acquisition unit on a chest of the simulated patient, the trainee hears a simulated biological sound reproduced from the biological sound reproducing means through the ear pipes, wherein the sound acquisition unit has a location display means for displaying its location, the location sensing means senses location where the sound acquisition unit is placed on a chest of the simulated patient by photographing the chest of the simulated patient and the location display means and performing image treatment, the biological sound database retains as information biological sounds containing respiratory sound and cardiac sound previously recorded in accordance with location of a chest of an actual patient, the biological sound reproducing means includes a voice reproducing apparatus attached to the simulated stethoscope, the biological sound reproducing means and the voice reproducing apparatus are wiredly and wirelessly connected, the biological sound reproducing means extracts predetermined biological sound information from the biological sound database corresponding to the location of the sound acquisition unit sensed by the location sensing means and emits reproduced biological sound from the voice reproducing apparatus, the emitted reproduced biological sound reaching ears of the trainee via the voice reproducing apparatus and the ears pipes, furthermore, the system comprises a timing display means for displaying a repetition of a timing of reproduced respiratory sound, the simulated patient can match his respiratory operation with a timing of a respiratory sound in the reproduced biological sound by observing the timing display means.
