They have come to be the favorite choice of many doctors, however there are reasons they the stethoscopes are a success.
- The stethoscope has unequalled standards when it comes to quality and the way that the stethoscopes had been manufactured. Some of the competitors’ stethoscopes are being manufactured in the Asian countries but Littmann stethoscopes are all made in USA.
- There are some models such as Cardiology IV model which offer the warranty of over 7 years. This shows how they were designed to last for a long period. It is possible to have a stethoscope that will last over 15 years.
- They are made with innovative technology: Littman uses a dual technology for frequency diaphragm which allows alternating between low and high frequencies auscultations. It is done by differentiating amount of pressure that it is applied on a patient. Littmann is also the leader in the market, when it comes to the modern electronic stethoscopes. However, it does not have too much competition now.
If you want to know more about Littmann, you have to start by learning about its dual frequency diaphragm. In the Littmann stethoscopes, the chestpieces have two membranes. There is a membrane that have small diameter and it is called a bell while another membrane has larger diameter and it is called a diaphragm. Within the stethoscope, every membrane has its own function. A bell is used to auscultate at low frequency but a diaphragm auscultate at higher frequency.
Since the dual frequency membrane is found at each side of a chestpiece, it is possible to auscltate at low and high frequency at the two sides.
When low pressure is applied at a patient, using a bell mode, then the doctor gets low frequency sound. If a firmer pressure is applied on a patient, or diaphragm mode, then the doctors get high frequency sounds.
With this innovation, the side of a small diameter may be used to get carotid and pediatric auscultations. All the stethoscopes from Littmann use the dual frequency membrane but not the one for Pediatric and infant use.
