Abstract
A stethoscope chestpiece is disclosed having an acoustic-to-electrical transducer residing within the acoustic pathway of the chestpiece. The transducer resides within a mounting that can provide shock attenuation and vibration isolation. The transducer preferably resides within a coaxial position in the acoustic pathway. The chestpiece is useful in a stethoscope which can be electrically connected to auscultation systems.
Claims14
A stethoscope chestpiece capable of transmitting auscultatory sounds both acoustically and electrically, comprising:
- (a) a stethoscope housing having a stem and forming an acoustic pathway for acoustic auscultation;
- (b) a mounting in the stem
- (c) a cable mounted within the acoustic pathway that is capable of transmitting electrically generated information:
- and
- (d) an acoustic to electrical transducer
- within the mounting in the stem of the chestpiece, wherein the transducer is electrically connected to the cable, and
- wherein the transducer is positioned within the same acoustic pathway as employed for acoustic auscultation.
