Stethotron has two modes of operation, amplification with filtering (Mode 1) and amplification only (Mode 2). Mode 1 filters out sounds below 350 Hz and above 1,000 Hz and used to listen specifically for vascular pathology. Mode 2 is used to listen for heart, lung, arteries, and other body sounds from 20 Hz to 20,000 Hz during routine physical examinations. Stethotron can be used on adult or paediatric patients undergoing physical examination. # Predicate Device to which Substantial Equivalence is Claimed The ProTron Technologies, LLC Electronic Stethoscope, Model Stethotron is substantial equivalent to the 3M Littman Electronic Stethoscope, Model 2000 cleared for market under Premarket Notification k961848. {1}------------------------------------------------ K082771 p²/3 Summary of how the differences in technological characteristic compare to the predicate device [807.92(a){6)]: | ProTron Technologies,<br>LLC Electronic<br>Stethoscope, Model<br>Stethotron | 3M Littman Electronic<br>Stethoscope, Model 2000 | Discussion | |---------------------------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | Two AAA alkaline batteries<br>(maximum 1.5 volts) | One AAA alkaline battery<br>(Maximum 3 volts) | A 1.5 volt increase in power<br>does not materially effect<br>the use or safety of the<br>device | | Two modes of operation,<br>Mode 1 amplifies the range<br>from 350 Hz to 1,000 Hz;<br>Mode 2 amplifies the full<br>range, 20 Hz to 20,000 Hz | Three frequency response<br>modes to choose from: Bell<br>(20-200 Hz), Diaphragm<br>(100-500 Hz) and Extended<br>Range (20-1,000 Hz). | Sounds from 20-1,000 Hz<br>can be amplified with both<br>devices.

Non-clinical Testing Brief Description: Testing to determine response and gain are equivalent to the predicate electronic stethoscope was preformed with a computerized audio analysis system sweeps a frequency oscillator from 20 to 10,000 Hz. This frequency sweep is presented to a transdicer on which the stethoscope is placed. The computer measures the response from the stethoscope with a small calibrated microphone placed in the eartip. The signal from the microphone is fed back to the computer where it is recorded, stored, and can be printed. The test was done in each of the two amplification modes, filtered and nonfiltered. ### Biocompatability All components of the Electronic Stethoscope, Model "Stethotron" have been reviewed for biocompatibility. With respect to ISO 10993-Part 1 Biological Evaluation of Medical Devices for limited (<24 hour) skin contact for both patient and/or health care professional exposure. Each component with potential skin contact with either the user profononal oxpeed or for possible health concerns. ProTron Technologies Company concludes that all of the components of the Electronic Stethoscope, Model "Stethotron" that make skin contact would have no potential for adverse health concern, all materials that make only to has this specified role that is equivalent to this device. {3}------------------------------------------------ ### DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/3/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
