That acutely popular design is a simple lumen stethoscope that will be ideally matched as a general examination stethoscope. The model 2144L, weighs in at only 160 grams and is 27" in Prezzo Farmaci. The Littmann smooth sealing head tips give exceptional noise transmission and comfort. Other functions carries a non-chill wheel and diaphragm and selection of accessible tube colors.The stethoscope was created in 1816 in France, but the daddy of the current day stethoscope was Dr. David Littmann of the Harvard Medical School. Whilst the founder of the Littmann stethoscope in the 1960's, his stethoscope is now the absolute most popular stethoscope on earth today.

The 3M organization bought the rights to the Littmann's stethoscope in 1967 and formed the 3M Littmann subsidiary. In the 1970's they produced the initial tunable diaphragm which permitted the consumer to check both high and low frequency sounds.In, 3M Littmann introduced the Littmann Common II Stethoscope. Ever since then it is becoming one of the most reliable and top quality stethoscopes that is used around the globe by tens and thousands of medical professionals.

The revolution in the 1970's Littmann style was that their tunable stethoscopes could be tuned for Bell Style (low frequency) or Diaphragm Setting (high frequency) with an easy change in pressure on the stethoscope chestpiece. That is achieved without having to turn on the chestpiece. Gentle contact on the chestpiece songs in the reduced frequencies and organization contact stress tracks in the large frequencies through the use of a 3M patented membrane system. The Littmann Master Traditional II, as with all Littmann stethoscopes, features a tunable diaphragm.

The lumen is the tube that operates from the chestpiece and splits at each binaural. Single lumen stethoscopes are great for most normal practitioners. Double lumen stethoscopes have two split up tubes or stations working from the chestpiece. Dual lumen methods are superior to single lumen programs simply because they are able to pick up reduced volume looks such as for instance center murmurs. Most cardiologists prefer applying double lumen stethoscopes. Littmann manufactures equally simple and dual lumen stethoscopes. The Littmann Master Traditional II includes a simple lumen.
