[Medical gels for ultrasonographic diagnosis, therapy and electrocardiography].

The All-Russian Research Institute of Medical Polymers has designed the medical gels REPAC, DIAGEL, for ultrasound diagnosis, REPAC-T for ultrasound therapy, ELCON and ELCARD for electrocardiography. REPAC, DIAGEL, and REPAC-T have the least sound damping factor (approximately 10(-3) dB/cm) as compared to other similar gels. REPAC and DIAGEL showed a good performance when they were applied in clinical practice during a year. REPAC-T is the gel that can be used both for ultrasound studies and for ultrasound therapy. Unlike REPAC, it has a longer drying-out time, ensuring a 100% contact between the patient's body and the transducer up to 20 minutes. Other gels have been designed for long-term ECG monitoring, bicycle ergometry, etc. ELCARD and ELCON have conductivities of 0.4-0.6 and 0.6-0.9 ohm/m, respectively.
