Doppler detector Bestman BV-620V
Doppler detector Bestman BV-620V. Doppler is designed to measure fetal heart rate (FHR) and is based on the use of the Doppler effect. During operation, the device emits an ultrasonic wave, which, propagating in the medium, is reflected from objects with different densities, and if the object from which the wave is reflected (the fetal heart) in the direction or against the movement of the wave, the reflected wave changes frequency, the device’s sensor counts the number of frequency changes per unit of time and converts it to the FHR value. Doppler with display of all data on the LCD display and printout of curves. The built-in microprocessor displays data in real time. Allows you to store up to 50 detected signals in the device’s memory. The Doppler can be connected directly to a computer to analyze, store and print signal data. Doppler determines: maximum and average blood flow speed; blood flow in peripheral vessels; systolic pressure; phlebostenosis, venous occlusion. Manba: https://www.nv-lab.ru/catalog_info.php?ID=6469
