Design of a STM32 based Portable System for Postpartum Recovery

Postpartum rehabilitation is one of the issues that pregnant women are very concerned about. In order to facilitate the postpartum rehabilitation nursing of spontaneous parturients, assist the restoration of uterus and save labor cost, this paper designs a non-invasive and easy to operate portable low-frequency pulse postpartum rehabilitation system to help parturients alleviate their physical and mental pressure and reduce their postpartum discomfort. The system uses stm32f103rct6 as the core controller, takes the belt as the carrier, and combines the pressure control module, temperature control module and low-frequency pulse module. The pressure control module is composed of pressure sensor, airbag and air pump. The temperature control module consists of a temperature sensor and a heating plate. STM32 collects the data of each module for analysis and processing, and transmits the data to mobile app or PC through Bluetooth module. The system can not only realize the functions of low-frequency pulse current massage, pelvic pressurization and dew discharge, temperature control and heat preservation, but also be safe, reliable and practical.
