Stethoscopes have long been in medical practice, dating back to 1816 when Ren├⌐-Th├⌐ophile-Hyacinthe Laennec of France invented the medical tool. Of course, the stethoscope went through many changes before finally reaching its modern design and style in 1852, thanks to George Cammann. The design and style not only give the stethoscope the look it has today, but they also improved its performance.
Of course, through the early 1900s, the stethoscope was refined and refined again, ever so slightly, to improve its effectiveness or to specialize a particular stethoscope to a very specific function. The most common type of stethoscope used today is the acoustic stethoscope. This two-sided stethoscope detects two different frequencies, one high and one low, and is the stethoscope most people see when they visit the doctor’s office.
Advancing the age-old use of holding the head to the chest to listen to the inner organs, thanks to the invention of the stethoscope, doctors now had the ability to listen to the lungs breath, the heart beat, the blood flow and the organs working.
Stethoscopes aren’t only used by doctors. Mechanics also utilize stethoscope technology to listen to the inner-workings of their machines, and we’ve all seen a bang-them-up movie where some hotshot used a stethoscope to crack open a safe. Even so, new technologies are being developed to help humans win over the metal competition.
And now, there is also an electronic stethoscope that is hitting the mainstream. Many people in the medical community believe that this is the up-and-coming stethoscope and that it will soon make the acoustic stethoscope obsolete. With these amazing features of modern stethoscope, it is important to market it to the medical market. This can be effectively done through media. Media specializes in medical practice marketing.
Electronic stethoscopes digitize the acoustic sound waves. Once the sound waves are digitized, they can be amplified and de-fuzzed to more accurately listen to what the body’s internal organs are saying.
There are many types of transducers, or ways to digitize the acoustic sound waves; and some are very basic and somewhat unreliable while others are much more sophisticated and accurate.
The first and most basic method digitizing is first to put a microphone in the chest piece and capture the sound directly where it is created. However, the downside to this practice of collecting sound waves is that the haplessly place microphone also records a lot of sound interference.
The Welch-Allyn’s Meditron stethoscope offers a different way of capturing the acoustic sound waves. This method requires the use of a piezoelectric crystal. This crystal, which acts as a transducer, is placed in the head of the metal shaft, which has direct contact with the diaphragm.
And yet another way to digitize the acoustic sound waves includes lining the entire inner surface with transducer-conductible materials, which is the style of electronic stethoscopes as created by Thinklabs.
3M also has several versions of electronic stethoscopes, but the big “seller” is the model that utilized the same type of piezoelectric crystal, but instead of being placed simply in the metal shaft, it is actually placed in a rubber-like diaphragm.
The companies producing most of the electronic stethoscopes on the market, and that are constantly working to refine and perfect the stethoscope, include Thinklabs, 3M and Littman. All have proven products that block out the ambient noise and amplify the way doctors listen to their patients’ bodies.
Stethoscopes have advanced the way doctors listen to the internal sounds of humans and animals alike, and have certainly offered new ways of understanding health problems. Stethoscopes also act as aids in identifying the effects of catching viruses and other nasty nemesis to our antibodies. As the technologies continue to be refined and enhanced, the existing electronic stethoscopes still have great abilities, and allow doctors to pause, rewind and record the internal body at work.
