微胎心 is an iPhone app developed by Beijing Chunwei Technology Co. LTD. It is designed for fetal heart monitoring and offers remote monitoring services for expectant mothers. The app works in conjunction with a specially developed fetal heart monitoring device that communicates with the phone via Bluetooth, uploading monitoring data to the cloud. Doctors can then analyze the uploaded data, provide remote diagnosis, and offer guidance to pregnant women. This app caters to the needs of hospitals, clinics, and expectant mothers who wish to perform regular checks at home. Users can view real-time fetal heart waveforms, listen to fetal heart sounds, and save and share the data. The app also includes features such as pregnancy tools, a community for pregnant women to communicate, and premium courses by experts.
