K-life Fetal doppler is a hand-held ultrasound probe which is used to detect the fetal hearbeat for prenatal care and alsoto help the families which are expecting feel closer to their babies. It uses the doppler effect to provide an audiblesimulation of the heart beat by detecting changes in the movement of the foetus. Thjs device can be used by healthcare professionals including nurses, midwives, specialized technicians in hospital, clinic, community, and nonprofessionals at home. Fetal Doppler detects fetal heart rate externally utilizing the principle of doppler shift of an ultrasound that the frequency shift of the reflected signal is proportional to the velocity of the reflecting structure-. The ultrasound is transmitted from the probe to the patient body that can transmit ultrasonic signal. when this ultrasonic energy is reflected back from the tissues, the reflected ultrasound is received by the probe and is converted into electric signals. These signals are sent to the CPU for processing on LCD Display.
