The E-Scope Electronic Stethoscope, cat. no. 718-7710 or 718-7750, is designed for individuals with in-the-ear (ITE) type hearing aids.  Both are supplied with low-frequency headphones that should be placed over the ears.  The ITE hearing aids are not removed.

Cat. no. 718-7750 is the same as Cat. no. 718-7710 except a Specialist Adult Bell is included.

 The dB level of the E-Scope Electronic Stethoscope is 130 dB SPL.  This is approximately 30 times louder than a normal acoustic stethoscope.  The difference between the above two models is that cat. no. 718-7750 is supplied with two Specialist Heads (bell and diaphragm) while model 718-7710 is supplied with a Specialist Diaphragm.  The Specialist heads are machined from high-grade stainless.  They provide a superior frequency input (by 50%) which improves sound sensitivity and they have a heavier feel and less likelihood of outside noise.  This is important for a hearing impaired user.

Both of the above electronic stethoscopes clip onto the belt or lab coat or the belt clip can be removed.  The normal stethoscope earpieces have been removed and replaced with an external set of low frequency headphones.  These headphones are placed over the ears without removing the hearing aid.  This has worked very well for the vast majority of hearing aid users.

Enclosed is the literature for your review.

The E-Scope Electronic Stethoscope amplifies the heart and/or breath sounds or Korotkoff sounds. It has maximum amplitude or sound pressure level output of 130 dB distortion without distortion (about 30 times that of an acoustic stethoscope).  Additionally, the sounds are amplified without appreciable amplification of room or background noise.  This makes it much easier to hear a low, rumbling murmur or faint AI blows.  A frequency switch allows the user to switch between heart and breath sound frequencies. The stethoscope has several features as follows:

1.  An output that allows the user to connect:

(a) to earphones for placing over the hearing aid, Cardionics cat. no. 718-0405 or 718-0415

(b) a second listener using a stethophone or headphone,

(c)  a PDA  for display of heart sounds on the pocketMONITOR software,

(d) a  computer or

(e) a tape recorder,

2.  A frequency switch for heart sounds (20-1000 Hz) and breath sounds (70-2000 Hz),

3.  A variable volume control,All the volume and filter controls are on the electronic stethoscope head allowing for one-hand control.

l4. Automatic Turn Off. A timer automatically turns the unit off after two minute to save battery life.  In fact, the E-Scope Electronic Stethoscope does not have an OFF button.  It turns itself off automatically and remembers the last volume setting so when it is turned on again, the volume is set to its previous level.

5. Battery. A replaceable, off-the-shelf AAA battery that will operate the E-Scope for approximately 4-5 months depending upon use.

6. Warranty. The warranty is one year and includes parts and labor.

7. Included Accessory items:

1. Extra ear tips.
2. A selection of diaphragms and bells.
3. Pediatric Diaphragm
4. Infant, pediatric and adult bells
5. Operator's Manual
6. Operational CD-ROM

IMPORTANT NOTE:  Hearing deficiencies vary considerably from person to person.  Your audiologist is the best source of information on your particular hearing problem.  You should consult with your audiologist if you have any specific questions about the use of your hearing aid with the E-Scope Electronic Stethoscope or any similar device.
