Littman electronic stethoscopes: A breakthrough in the field of biomedical engineering.
Stethoscopes have been used by doctors since long ago to diagnose different ailments and body disorders. The first stethoscope was invented by a French physician, Rene Laennec. It was wooden in nature and had a large circular base.
Stethoscopes have been used by doctors since long ago to diagnose different ailments and body disorders. The first stethoscope was invented by a French physician, Rene Laennec. It was wooden in nature and had a large circular base. The sound was converged to a small opening into the ear of the listener. But since then, stethoscopes have gone through lots of modifications and innovations. If you compare the modern day stethoscopes with the first wooden one, you would be surprised at the number of features the new ones provide. These features make the stethoscopes more convenient and easy to use.
Until recently, doctors used acoustic stethoscopes to examine patients. But one of the most common problems that they faced with acoustic stethoscopes included the difficulty in listening to the sounds with less magnitude. Moreover, listening to such faint sounds in a loud environment was next to impossible. But as technology improved, we witnessed the birth of electronic stethoscopes. The major advantage of an electronic stethoscope is that it can amplify a weak sound up to an audible level. One such brand that manufactures excellent electronic stethoscopes is Littmann. A Littman electronic stethoscope is an epitome of quality. Many of the doctors and other medical practitioners from around the world prefer using these electronic stethoscopes.
A Littman electronic stethoscope is bundled with a lot of advanced features. This electronic stethoscope receives acoustic waves from the body, and converts them into electrical signals. As you know, electrical signals are a very convenient form of energy, as they can be modified as well as stored. This sound, which is in the form of electrical signals, is filtered and amplified and then converted back to sound energy. Thus, the listener is able to hear clear body sounds without any interference. The Littman electronic stethoscope is also provided with a feature that enables it to vary the magnitude of sound depending upon the loudness of the sound. For example, you can increase the volume of the output of the stethoscope for weaker sounds, and decrease it for stronger ones. A Littman electronic stethoscope also comes with a very useful feature, known as noise reduction. It is able to reduce the background noise to up to 85%. Thus, it makes it possible for the listener to hear faint bodily sounds even in a noisy environment.
Thus, it becomes really easy for a doctor for further evaluation or consultation as he/she can replay these recorded sounds later. In case of traditional acoustic stethoscopes, you would have had to flip the stethoscope to hear low frequency sounds from the bell side and high frequency sounds from the diaphragm side. But a Littman electronic stethoscope has another important feature that enables it to electronically switch between two modes, viz. the diaphragm mode and the bell mode. Moreover, a Littman electronic stethoscope is extremely durable and light in weight. The life of any human being is extremely precious and it is a stethoscope that assists in the first level of examination. Hence, buying the best electronic stethoscope available in the market makes perfect sense. The only name that springs to mind is Littman electronic stethoscope.
