Abstract:Objective In order to build a platform of medical internet of things to make doctors and patients exchange the therapeutic information in a long-range and real-time way,the multi-parameter life monitor represented in this paper can realize real-time monitoring of electrocardiograph (ECG),respiration, blood oxygen,pulse,fall behavior and body temperature.Methods A double-layer structure is adopted,the lower layer is signal acquisition board and the upper layer is cc2430 microcontroller.Real-time signal algorithms which include signal preprocessing,characteristic wave detection and parameter calculation,are used in the monitor.Then the parameters are used to form a tentative diagnose.Finally,the tentative diagnose is delivered to cc2430 and transmitted by the zigbee module of cc2430 to the home gateway.The home gateway is responsible for transmitting the tentative diagnose to the remote medical station and waiting for a further diagnose from the doctor.Results The monitor successfully implements the acquisition of physiological signals and the real-time processing of signals. Conclusions This multi-parameter life monitor can monitor the patient in a real-time way and can be successfully applied to the medical internet of things.
