A frequency switch for heart sounds (45-900 Hz) and breath sounds (50-2000 Hz). This allows the listener to concentrate on a particular sound. The E-Scope shuts off automatically at or about two minutes. The E-Scope remembers the last volume setting so that when it is turned on, the volume will be set to the previous volume.

The E-Scope uses a standard off-the-shelf AAA battery that operates the E-Scope for 4-5 months assuming usage at 30 times per day, 6 days per week. The E-Scope is supplied with two additional types of ear tips so the user can select the most comfortable soft rubber, hard plastic or mushroom type.

Most electronic stethoscopes have a fixed diaphragm with an electronic switch to change to a bell. Most physicians, however, prefer a physical bell as is found on a standard acoustic stethoscope. A real bell allows the physician to listen to lower frequencies in a manner in which he/she is most accustomed. A bell is used to listen to the lower frequencies and has no diaphragm touching the skin. By pressing the bell on the skin, it can be stretched forming a natural diaphragm.

The E-Scope is supplied with an adult and pediatric diaphragm as well as three sizes of bells: adult, pediatric and infant.

The design of the E-Scope significantly reduces the amplification of unwanted outside room noise when used in the heart sound setting. When used in the lung sound setting, there is a little more noise introduced due to the wider frequency band.

For the E-Scope II, the maximum amplitude or sound pressure level output without distortion is 120 dB at 100 Hz. This is about 30 times louder than an acoustic stethoscope.

A complete Operator’s Manual as well as an informal instructional CD-ROM is included with each E-Scope.

Cardionics supplies a Specialist Adult Diaphragm as standard on all E-Scopes. An optional Specialist Adult Bell and Specialist Pediatric Bell are available. The performance of the Specialist Adult Diaphragm has a 3 dB (or 50%) higher output than the standard Diaphragm over the 20 to 200 Hz frequency range. Specialist is a trademark for a series of chest pieces machined from high-grade stainless steel.

The Specialist Pediatric Bell output has, on average, about 60% higher than the standard pediatric bell over a 50 to 200 Hz frequency range for both heart and breath sound filter settings.
