Design specifications Component and Operation overview including power, portability, facility requirements, preventative maintenance and user training requirements

The Fetascope is made from plastic and has a cone-shaped opening on one end, which is placed on the pregnant abdomen. On the other is a flat surface, which is held to the ear. Sound is conducted from one end to the other through a hollow tube, which amplifies the sound of the heartbeat. Use of this instrument requires practice to locate and correctly assess fetal heart rate, which can sometimes be obscured by ambient sounds or the position of the fetus. To determine the position of the fetus the Fetascope must be pressed to a location very close to the fetal heart, providing a relatively accurate indication.

This Fetascope includes reminders for dangerous warning signs in a pregnancy and is available in Haitian Kreyol, Spanish, English, and French.

Manufacturer specified performance targets Designer / Manufacturer specified targets

Portable and durable device. The sound is best heard over the fetus’ back beginning at 18-20 weeks of pregnancy.

Vetted performance Findings of manufacturer evaluations or independent testing centers

The Pinard Horn is a proven technology in use since the 19th century. Overviews and studies of effectiveness of the Fetascope are limited. Maternova lists field reports from Malawi and from Uganda.

Testing organizations Independent lab, academic research centers, etc.

The basics of maternal and newborn care guide by JHPIEGO references the Pinard Horn as a useful tool. Few known organizations indicate test outcomes because studies using Pinard Horns are informal due to the low-tech nature of the product.

Other information

The Fetascope may more precise than a Doppler device for determining fetal positioning as a Doppler device detects a heart tone farther away from the location of origin.
