Aviation Style Headphones. To minimize outside noise and enhance comfort, the E-Scope EMS Electronic Stethoscope utilizes aviation-style headphones. The padded seal around the ears and insulation inside the headphones significantly reduce outside noise allowing the paramedic to hear soft breath and/or heart sounds in an ambulance or other noisy environment. The ear pads provide cushioned comfort for long-term use.
Cable length. The cable length on the E-Scope EMS is 36 inches.
Finger-tip Control. All the controls for volume and heart sound or breath sound filters are on the stethoscope chest piece and as well as on the headphone.
Volume Control. On the stethoscope chest piece, the + or – symbol is pressed to increase or decrease the sound volume. On the headphone, a toggle switch increases or decreases the sound volume. The toggle switch is easily operated with a gloved finger.
Breath and Heart Sound Filter Control. Since breath sounds are in the 50-1600 Hz range and heart sounds are in the 50-700 Hz range, the E-Scope EMS can be adjusted to concentrate on these frequency ranges. The · symbol on the stethoscope chest piece switches the frequency response between these two ranges. A push button on the headphone is also available for a quick frequency response change.
Automatic Shut Off. To extend the life of the AA battery, the E-Scope EMS shuts off automatically after 1.5 minutes (an optional 8-minute shut off is available.)
Automatic Volume Restart. When the E-Scope Electronic Stethoscope is turned ON, it remembers the last volume setting thus keeping new volume adjustments to a minimum.
Off-the-Shelf Battery. The E-Scope EMS uses a standard off-the-shelf AA battery that operates the E-Scope EMS for about 5 months assuming usage at 30 times per day, 6 days per week. Replacement batteries are available wherever batteries are sold.
Selection of diaphragms and bells. The E-Scope EMS model is supplied with a Specialist Adult Diaphragm Adult Bell. This model is also supplied with a pediatric diaphragm.
Specialist Bell. Cardionics supplies an optional Specialist stainless steel bell (shown below) as well as a Pediatric Specialist Bell. The performance of the Adult Specialist Diaphragm has a 3 dB (or 40%) higher output than a standard stamped metal Diaphragm over the 20 to 200 Hz frequency range.
 Specialist Diaphragm. The E-Scope EMS is supplied with the Specialist Adult Diaphragm (shown below). Machined from high-grade stainless steel and fitted with a plastic non-chill ring for patient comfort, the Specialist Adult Diaphragm has a sound sensitivity more than 40% greater than a stamped metal or plastic diaphragm while reducing outside ambient noise.
Less amplification of room noise. 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.
Maximum Amplitude. 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.
Operator’s Manual and Instructional CD-ROM. A complete Operator’s Manual as well as an informal instructional CD-ROM is included with each E-Scope.
E-Scope uses. General clinical medicine, medical professionals who wear hearing aids, paramedics for ambulance use, isolation wards and Hazmat areas and cervical auscultation (speech pathology). |
