Ultrasound Transmission Gel (250 ml)Transound ultrasound transmission gel for diagnostic and 
therapeutic medical ultrasound. Recommended for all procedures where a viscous gel is required, 
including Ultrasonic diagnosis, Ultrasonic therapy, ECG, EEG, EMG, Defibrillation etc. Why Do I Need 
Ultrasound Gel? Applying a layer of ultrasound coupling gel between the Doppler sensor and tummy can 
ensure a clear signal for detecting the fetal heart beat. Doppler sound waves do not travel easily 
through the air and so without the use of coupling gel, high interference prevents a clearly audible 
sound.
