The pregnancy disc is an obstetric calculation tool that is not considered a medical device, designed to predict the possible date of delivery. It provides a quick and visual method to estimate the gestational age and the expected delivery date.

Design and Features

The disc is made up of two concentric rotating discs riveted at the center, allowing for immediate calculation of the weeks of gestation and the estimated date of delivery. Its simple mechanical construction makes it intuitive and durable for daily use.

Areas of Use and Clinical Benefits

Indicated for obstetricians, gynecologists, outpatient operators, and healthcare personnel involved in obstetric wards or prenatal clinics. It can also be used in home settings for educational activities or obstetric counseling. It is useful for supporting quick clinical decisions such as the timing evaluation for medication administration during pregnancy and for scheduling obstetric follow-ups.

Main Advantages

Ease of use, immediate response without the need for power supply or electronic tools. As a non-medical tool, it is easy to disseminate in educational and outpatient contexts where a quick estimate is needed.
