Welch Allyn Electronic Stethoscope Guide

A

Since 1915, Welch Allyn has been a company dedicated to bringing you the best in diagnostic instrumentation for the front line health care professional. The new Welch Allyn Electronic Stethoscope continues this tradition. The Welch Allyn Electronic Stethoscope based upon proprietary technology from Meditron AS - provides superior sound reproduction due to its sensor-based methodology. Other electronic stethoscopes depend upon a microphone for sound reproduction. Unfortunately, no matter the fidelity, microphones pick up ambient noise in the environment transmitted through the stethoscope diaphragm and chestpiece.

[thedistributor) is designed for use when there is a need for several people to listen to a patient simultaneously. By using [thedistributor), up to six people can participate. The "Master" listener controls the auscultation process with his or her stethoscope. Others are co-listeners who will hear the same sounds by connecting their stethoscopes or headsets to [thedistributor). Up to three groups of listeners may be linked together with additional [thedistributor)’s as needed for larger groups.

The Welch Allyn Electronic Stethoscope utilizes a highly directional, recessed pressure sensor which eliminates much of the ambient noise in the environment while faithfully reproducing body sounds in the same "color" as a traditional Welch Allyn stethoscope. Amplification can be varied as desired by the practitioner. Recognizing the need for improved auscultation skills, the Welch Allyn Electronic Stethoscope is just one part of a complete teaching and diagnostic system. When combined with [thedistributor) - a product for sending sounds from the stethoscope to others and [theanalyzer) - a software accessory for recording sounds and phonocardiograms, the Welch Allyn Electronic Stethoscope System is a powerful addition to any hospital, clinic, or health care professional's diagnostic toolbox.

[thedistributor) has an automatic On and Off function. The unit turns itself on automatically when the master stethoscope is on and a signal is detected. This takes place shortly (0.5 seconds) after the On button of the stethoscope is pressed. Please note that the unit can only be turned on from the master stethoscope. As long as signals are being emitted by the master stethoscope or the PC, the unit will remain on. When [thedistributor) is on, the diode will light up. [thedistributor) will remain on for one minute after all signals have ceased.

The stethoscope that carries out the active listening must be connected to the external cable port marked "Master". Use one of the accompanying cables and make sure the plugs are properly pushed in. When the ON/OFF button is pressed, the audio signal will go to [thedistributor). The unit will then turn itself on and the diode will light up. The "Master" is then controlling the unfiltered auscultation signal that is being fed into [thedistributor).

Co-listeners link their stethoscopes or headphones to one of the external cable ports marked from 1 to 5. If you are using a Stethoscope, use the accompanying cables and ensure that the plugs are properly pushed in. Users will now experience the same sound as the "Master". For listeners using Headsets, the volume and frequency control on [thedistributor) can be used in a similar way to that of the stethoscope. For listeners using Stethoscopes and not Headsets, it is important that the frequency selector should be in the middle position.

PC

Light-emitting diode

Batteries

This external cable port should be used when the user wants to send an audio signal to a PC for visualisation, storage or further processing in the software program.

The green light-emitting diode located in the top cover of the unit has two funtions: 1: ON/OFF indicator. 2: Battery indicator. The unit will turn itself on and the diode will light up when a signal is received from the stethoscope. If no signal is received, the unit will turn itself off after one minute. A blinking diode indicates that the batteries are weak. No light indicates that there is no signal or that the batteries are completely drained.

[thedistributor) runs on two easily replacable highenergy TL-5902 lithium batteries with an international reference size of 1/2 AA, ER14252. The batteries are estimated to provide an effective listening time of 200 hours. Change batteries by pushing the cover back. Check that the batteries are installed with the correct polarity.

Choosing the frequency [thedistributor) has filters for three predetermined frequency ranges. The filters are controlled with a small selector switch. 1. Pulmonary (H: High-frequency sounds) 2. Wide listening range (Mid-position) 3. Cardiology (L:Low frequency sounds)

Volume control [thedistributor) is equipped with a variable volume control. Turning in the direction of the arrow reduces the volume.
