Subjective monitoring of fetal movement activity of pregnant woman is a simple and effective method to verify physiological condition of the fetus. Mother perceives the characteristics and frequency of fetal activity during the day throughout second half of pregnancy and is able to identify when fetal activity is present. By the time mother realizes that she no longer feels fetal activity and visits the doctor, it is usually too late and the fetus is dead (4 deaths per 1000 children born per year in Czech Republic). Despite comprehensive prenatal care for pregnant women, this number has not been reversed in the last 20 years. The aim of fetal movement activity monitors is to provide monitoring of the fetal movement activity (during the sleep and in case of certain doubts during the day) so that the pregnant woman visits the doctor in time when suspects changes in the natural characteristics of the movements in order to prevent fetal death.
A system of sensors placed under the mattress of the pregnant women was developed. The data obtained from the sensors were compared with the actograms of pregnant women (fetal movement activity records) obtained by the CTG (cardiotocography). The graph shows a comparison of the output from the actogram (black curve indicating fetal movement activity) with calculated fetal movement activity detected by the sensors in the pad. In the calculated activity is then possible to determine a threshold value above which the fetal movement activity is considered relevant. Further development would consist in optimizing the parameters of the algorithm to determine present movement activity in order to improve basic characteristics of the method, sensitivity, resp. specificity, which is now 80%, resp. 60%.
Simple and easy to use: Non-wearable - Homecare / Medical facility use.
Automatic evaluation giving an information when the last sufficiently intense activity of the fetus occurred after about 15 minutes of measurement.

Technology is owned by University Hradec Králové together with University Hradec Králové. Czech patent application PV 2021-360 was submitted (priority date 30. 07. 2021). PCT application is planned to be submitted on June 2022. Prototype testing in progress. Potential application is IVD test - POCT is intended to be used my medical facilities that take care of pregnant women esp. regional hospitals or perinatology centers. Final product could be whether certified pregnancy monitor for home use or medical device. We are searching for manufacturer of deviced for home health monitoring or medical devices manufacturer.
