Monaural
Stethoscope
c 1870s
The first stethoscopes were wooden
hollow tubes.
This monaural stethoscope has a removable shaft that could be carried
inside
a physician's top hat. The bell at the left of the photo was
placed
against the chest with the broader end against the ear of the
examiner.
17 cm in length. |
In
1818, Francois Mayor of Geneva
first described
fetal heart sounds in pregnant uterus, but did not recognize the
clinical
importance of the sound. It was Jean de Kergaredec, a student of
Rene Laennec, in 1822 published the clinical significance of the
fetal heart rate. |
A.
Pinard, (c. 1880s
) a French doctor, developed a technique of abdominal palpation
and
manipulation of the fetus. Subsequently, he developed a one piece
monaural fetoscope to listen to fetal heart beat on pregnant
patients.
It has a broad flat ear piece and a wide flaring fetal side. The
Pinard's fetoscope was used from 1880s thru early 1900s. The
Pinard's
monaural aluminum is still used in obstetrics up to the 1990s in
Eastern
Europe.
