Subject actuated system and method for simulating normal and abnormal medical conditions

1 . A system for simulating medical conditions to facilitate medical training, the system comprising:

a stethoscope comprising an earpiece and a headpiece and configured to transmit information indicative of a medical condition, and

a triggering device configured to activate the transmission of the information.

2 . The system of claim 1 , wherein a subject is trained to activate the transmission of the information using the triggering device when the location of the stethoscope coincides with a predetermined set of regions.

3 . The system of claim 1 , wherein the information indicative of a medical condition is a sound transmitted through the earpiece of the stethoscope.

4 . The system of claim 1 , wherein the sound is a naturally occurring sound.

5 . The system of claim 1 , wherein the sound is a digitally processed or altered sound.

6 . The system of claim 1 , wherein the sound is at least one of: normal breath sounds, crackles, wheezes, stridor, pleural rub, normal heart sounds, pathologic splitting, murmurs, clicks, gallops, pericardial friction rub, venous hum, bowel sounds, and bruits.

7 . The system of claim 1 , wherein the medical condition is at least one of: bronchitis, heart failure, lung consolidation, pneumonia, atelectasis, pleural effusion, pneumothorax, chronic obstructive pulmonary disease, emphysema, asthma, healthy lung function, mitral valve prolapse, mitral regurgitation, mitral stenosis, pulmonic stenosis, aortic stenosis, aortic regurgitation, ventricular septal defect, pericarditis, healthy heart function, bowel obstruction, renal or aortic artery bruits, normal abdominal function, and carotid artery bruits.

8 . The system of claim 2 , wherein the predetermined set of regions comprises regions over the heart, lungs, carotid artery, renal artery, and abdomen of a subject being examined.

9 . An apparatus configured to transmit sound indicative of a medical condition, wherein the transmission of sound is activated by a triggering device.

10 . The apparatus of claim 9 , wherein the apparatus is a stethoscope comprising an earpiece and a headpiece.

11 . The apparatus of claim 9 , wherein the triggering device uses short-range wireless signals to activate the transmission of sound.
