Doctor David Littman, a renowned heart doctor, creator, and Harvard Medical School professor, greatly improved the the stethoscope
of stethoscopes in 1963. The man believed it was important to have access to a stethoscope with two bells, an open one to listen to lower pitch sounds and a closed, flat chestpiece to listen to higher pitched sounds. Dr Littmanns' ideas enabled physicians to get better diagnostics on their patients body sounds. In place of only being able to experience the lower or higher pitched sounds exclusively, Drs were able to hear both frequencies with one stethoscope. The Littmann Stethoscopes have advanced tellingly through the years. Littman Stethoscopes are dynamite for general physical assessment and for cardiology.
There are several types of Littman stethoscopes on the market. 3M bought Dr. Littman's cardionics inc in 1967, keeping him on as a consultant and creator. There are now regular acoustic Littman stethoscopes and electronic stethoscopes that afford even greater amplification. The greatest improvements on the original configuration was the invention of the tunable stethoscope. A tunable stethoscope features the diaphragm and bell on a single chestpiece instead of two. a physician can lightly press the bell or diaphragm to the skin to use the bell side to hear lower frequency body sounds. Nurses who want to hear for high frequency sound can apply more pressure to the chestpiece, which will flatten it and makes a regular diaphragm.
The Littmann stethoscopes are widely used by nurses and other specialists who want the greatest amount of accuracy and sound amplification from their instruments. While specialists worldwide trust Littman stethoscopes, general practitioners use them for routine physical exams as well.
3M's Littman stethoscopes are esteemed for their sureness, dependability, and good feeling for both the patient and the doctor alike. There are a number of stethoscope models applicable that are built for application in many environments, from the pediatricians office to the operating room.
