Dr. David Littman, a famous cardiologist, inventor, and Harvard Medical School professor, greatly improved the acoustic qualities of stethoscopes in 1963. He believed it was important to have a stethoscope with two chest pieces, open can be used to listen to the deep tones and a closed head plate, for receiving the highest sounds. His ideas enabled doctors a faster and more accurate measurements of the internal sounds of the patient's body. Instead of just listening to the situation, low or high notessounds exclusively, doctors were able to listen to both frequencies with one stethoscope. Littman stethoscopes have evolved over the years. Littman Stethoscopes are great for general medical and cardiology.
There are many types of Littman stethoscopes on the market. 3M bought Dr. Littmann Cardio Sonics Company, Inc. in 1967, continues the doctor as a consultant and designer. There are now a standard acoustic stethoscopes Littmann and more recent electronicModels that provide even greater amplification. One of the biggest improvements to the original design was the advent of tunable stethoscope. A tunable stethoscope, the diaphragm and bell chest piece instead of two. The doctor may gently pull the breast skin of the patient to use the bell to hear low frequency sounds. Physicians who want to hear high-frequency sound pressure over the head, which flattens and makes a traditionalMembrane.
Littman stethoscopes are widely used by cardiologists and other specialists that the maximum precision and sound from their instruments need amplification. While the specialists from around the world trust Littman Stethoscope, family doctors use it for routine physical exams.
3M Littmann Stethoscopes are regarded for their precision, reliability and convenience for both physicians and patients. There are a number of models available that are designedfor use in a variety of settings from the operating room of the pediatric study.
