The ER Premier is a robust and versatile stethoscope with superior acoustic quality that enables physicians to deliver fast and efficient emergency care to both pediatric and adult patients using just one stethoscope. Also with an included Bell conversion this stethoscope can be transformed into Classic Cardiology Stethoscope. Precisely handcrafted from premium stainless steel for the highest performance and unmatched durability in any emergency medical setting.
Chestpiece: The cardiology-type dual-head chestpiece and full-rotational acoustic valve stem are machined and polished to the exact tolerance from the finest stainless steel. The adult diaphragm side and pediatric diaphragm side are fitted with an ultra-sensitive diaphragm sealed by the diaphragm retaining ring to produce optimum amplification and high-frequency transmission of heart and lung sounds at 100 to 1000Hz. The diaphragms are crowned with a non-chill durable PVC diaphragm retaining ring to provide greater patient comfort.
ErgonoMax Headset: Machined and polished stainless steel tubes are enlarged to provide superior acoustic transmission. Enclosed double internal spring and MDF ComfortSeal eartips are ergonomically designed for long lasting fit and comfort.
Acoustic Tubing: Combined dual acoustic tubes with enlarged internal acoustic pathway in the Y configuration sustain the superiority of double tube acoustic transmission and eliminate internal acoustic leakage and external interference. Acoustic tubes are constructed of non-cracking, non-sticking high-density latex-free PVC.
I decided to take a chance and go with the MDF ER scope instead of the Littman. I think I did okay. It has an excellent range of sound. I was able to auscultate some abnormal heart sounds on some nursing home patients much better with this scope than others I have tried (without even using the cardiac adapter that comes with it). It is well constructed and comes with the free parts for life which covers the ear pieces and diaphrams. I'm sure there are better scopes out there, but for the money I think it was a good long term purchase.
