Development Of Wearable Multiple Physiological Parameters Health Monitoring System

Human physiological signals can reflect human's health status,It is an important reference for clinical diagnosis and medical care,therefore,it is of great significance to monitor the multi physiological signals simultaneously.With the development of modern economy and the progress of science and technology,People's health awareness is also gradually improved,and put forward more requirements for the modern medical field of human physiological signal monitoring.The physiological signal monitoring equipment of the future will not only physiological signal detection of the human body,but also to the various human physiological signals were analyzed to assess the health state of human body,but also can analyze and track the development of some diseases.The traditional multi physiological parameter monitoring device of human body is usually used to measure the ECG and respiratory signals of the human body by a disposable Agcl electrode,it is uncomfortable and inconvenient.In addition,the traditional human physiological parameters monitoring device is relatively large,and use of wired connection,limiting the use of occasion,generally used only for ward bedside monitoring.In order to meet the above requirements,this paper designs a wearable multiple physiological parameter monitoring system,realized Wearable measurement of human physiological parameters without lead line.The main contents of this paper are as follows:1?In this paper,the basic physiological mechanism and characteristics of different physiological signals were studied.Designed The measurement methods,hardware circuits and processing methods for the specific physiological signals;2?Using the fabric electrode and the clothing as the ECG and respiratory signal sensing device,the body surface of the ECG signal and impedance respiratory signal were extracted;3?The photoelectric pulse sensor is used to collect the pulse wave signal of human body and according to the pulse wave data,the value of oxygen saturation is calculated;4?The ECG and pulse wave data design algorithm for continuous measurement of blood pressure without cuff based on the pulse wave transit time;5 ? Used Infrared temperature sensor for non contact measurement of body temperature;6?Based on the acquisition of the three axis acceleration signal of the human body,the algorithm is designed to judge the human body motion attitude and realize the human fall detection;7 ? Design of low power consumption and small volume of human multi physiological parameter measurement module,realize the measurement of multiple physiological signals at the same time,and realize the wireless transmission of human physiological signals,to upload data to the handheld terminal and the computer analysis system,and the data can be stored in the SD card,the data processing module to facilitate the acquisition of offline;8?Experiments show that this system is valid,sustainable and accurate.
