Stethoscopes
| Stethoscopes have undergone dramatic development since Laennec first began using a hollow wooden cylinder in the early 1800s. By the end of the 19th century, flexible, binaural stethoscopes were quite common. Although some physicians felt the invention of the stethoscope weakened the physician's own powers of diagnosis, the stethoscope offered an immediate diagnosis at a minimal cost and improvements on it continue to be made. |
