E-Steth is the original digital stethoscope that isolates and amplifies heart and lung sounds. It is supplied with a choice of normal "Lyer" style headset or "Hi-Fi" headset for hearing impaired users, CardioMail software CD, instructions and cable for connection to a PC.

Features: * Listen with clarity to both heart and lung sounds. * "Store, forward" and compare visual images of the heart and lung, then print, fax or email the results.

E-Steth is used to detect the following pathologies:

Pulmonary: Asthma, bronchitis, pulmonary fibrosis, pneumothorax, pulmonary lobe consolidation, pneumonia, pleural rub.

Heart (morphology): Two pathologies for each heart valve: stenosis and insufficiency, pulmonary, tricuspid, aortic and mitral valve auditory and visual phonographic readings, mid-systolic click - murmur, interventricular septal defects, including atria and ventricals, left ventricular systolic dysfunction.

Heart (conduction): E-Steth can aid in the diagnosis of cardiac rhythm disturbances.

E-Steth and CardioMail are effective in diagnosing difficult conditions, such as: Pleural rub, pericardial rub and valvular function.

The hi-fi headset for the SC-450 E-Steth is designed for hearing impaired users.

This state-of-the-art auscultation system consists of an electronic stethoscope with analytical software and an auscultation sound database. The database system allows even inexperienced doctors to make an accurate diagnosis while sounds can be recorded directly onto a PC for phonocardiogram view.

Features:

* Mode: Bell / diaphragm / wide. * Amplification 18x. * Simple button operation. * Mode and volume settings memory. * Hand tremor and ambient noise protection. * AAA battery operation. * 50 hour operation with power save function. * Auto off. * Low battery indicator. * Weight 170g without batteries. * Connects to PC, MP3, Walkman, hi-fi system etc. * Real time body sound monitoring. * Graphic display of heart beat sound. * Signal transmission via the Internet. * Heart beat rate calculation. * Database management. * Recording / archiving / analysing function. * Frequency range filtering.

The new SoundPlus stethoscope gives great performance with a sleek, modern design.

Its unique piezopolymer contact microphone avoids the problem of signal loss associated with stethoscopes which have an air layer between the skin and stethoscope and sound is amplified up to 14 times.

Features include:

* Black and chrome high quality durable materials. * Soft-seal eartips. * Wide frequency response characteristics. * Improved low frequency sound transmission. * Microprocessor controlled auto-off. * Three level battery condition indicator lamp. * 3V lithium battery operation giving up to 150 hours continuous use.

* Coming soon: SoundPlus PDA digital diagnosis system and SoundPlus transmitter module for computer use.

The Littmann 4000 amplifies sound up to 18x louder than the best Littmann conventional stethoscope and has storage and playback facilities with infra red data transmission . Features:

* Built-in microphone, filtering circuits and low-noise amplification. * Generates superior acoustical response. * Filter circuitry provides three different responses, bell (20-200Hz), diaphragm (100-500Hz) and extended frequency (200-1,000Hz), which are where all heart and lung sounds occur. * Chestpiece display of heart rate between 30-199bpm. * Recording, storage and playback capability for 6 different auscultations, either normal or half speed. * Download of recorded sounds via infra red data transmission to IBM compatible PC or another Litmann 4000. * Lightweight alloy ear tubes with patented Littmann Snap Tight Soft-Sealing Eartips. * Ensures a better read on both normal auscultation and difficult-to-hear sounds. * Battery operation (2 x AAA) 20 hours for listen only mode. * Total length 69cm. * One year warranty.

A new concept in stethoscopes.

Sonoplus 2000 is fitted with an extraordinary acoustic system based on patented AIS (Anti Interference System) technology, providing a clear heart beat. It has the ability to record an ECG and freeze it to show ST-elevation or allow for arrhythmia or other phenomena to be checked.

* High sensitivity membrane with anti-interference device. * Hi-lo frequency pick up depending on applied pressure. * ECG and heart rate display. * Single push button operation. * Compliant with RL3/42 EWG safety norms. * Operated by 2 x AA batteries (supplied). * 180gm weight.

The Sonoplus 2000 is packed in a stylish carry case, including all accessories: *Batteries. *Gel. *Gel dispenser.

Reliable, easy-to-use, precision electronic stethoscope.

* Detects all significant sounds including murmurs, pulmonary function, foetal and cardiac sounds. * Overcomes impaired hearing. * Penetrates clothing and filters out environmental noise. * Ideal for use in busy and noisy general practices and clinics.

* Built-in microphone, filtering circuits and low-noise amplification. * Generates superior acoustical response. * Filter circuitry provides three different responses, bell (20-200Hz), diaphragm (100-500Hz) and extended frequency (100-1,000Hz), which are where all heart and lung sounds occur. * Amplifies sound up to 4x louder than the best conventional stethoscope (15-20dB). * Ensures a better read on both normal auscultation and difficult-to-hear sounds. * One year warranty.

Electronic stethoscope includes amplification and filtering system, ideal for picking up difficult-to-hear heart and other body sounds. With following features:

* Fully electronic, eliminates the aphonic and resonance effect.

* Audio frequency is divided into 3 selective modes. Standard bell (26 V 200 Hz), Diaphragm (100 V 500 Hz). and Extended diaphragm (100 V 1000 Hz).

* The electronic amplifying system allows adjustment to 8 volumes (0-18 dB)

* An accurate sound filter enhances the articulation of sound collection.

* It amplifies responses of preferred low frequency sounds and filter and the undesirable ambient noise of high frequency.
