Research on Physiological Parameters Monitor Based on Multi-Functional Device

In accordance with the special requirements of medical devices, this paper describes the software design process of a physiological parameters monitor based on multi-functional device. The physiological parameters monitoring software achieved serial communication with physiological parameter acquisition module by adding MSComm widget. The monitoring software is designed into multi-view structure for the 5-lead ECG and 7-lead ECG drawing and it displays various parameters of patient and monitor on its dialog bar and status bar. When the monitor gets dangerous physiological signal form patient, the software drives speaker to sound in corresponding way, at the same time, it drives GSM/GPRS module to call for help by sending corresponding message to preset phone number. Test results showed that the monitoring and operational performance of the monitor reached expected requirements and both the two alarm modes could work correctly.
