Vaginal stethoscope for early diagnosis of pregnancy. Falls (Amer. journ. of obst., v. 11, Berich., Bd. X)
The instrument is a combination of a long wooden stethoscope with special tubes for listening through the vagina. The stethoscope is placed against the portio vaginalis and waited for the fetus to turn its back toward the cervical canal in its movements, as this is when the heart sounds are clearest.
