Pocket Fetal Doppler

The Pocket Fetal Doppler is an essential tool for prenatal care, allowing for the detection of fetal heart rates from the twelfth week of pregnancy. This compact and portable device is designed for both home and clinical use, making it convenient and accessible. With its built-in loudspeaker, connection for a recorder and earphone, and large backlit LCD display, it provides clear and accurate readings. The LCD measures 37mm x 23mm, ensuring visibility in all lighting conditions.

Product Use:

The Pocket Fetal Doppler is primarily used by expectant mothers, obstetricians, midwives, and other healthcare professionals to monitor fetal heart rates (FHR). It is a valuable tool in prenatal care for assessing fetal well-being and detecting potential issues early. This device is also used by students and nurses for training and educational purposes, making it an indispensable asset in various medical settings.
