Device for monitoring heart rate and physical state

Abstract

The invention provides a device for monitoring heart rate and physical state. Sensors are mounted on a waistband, and the device comprises a data acquisition module, an FPGA (Field-Programmable Gate Array) control module and a DSP (Digital Signal Processor) data processing module. When the heart rate and the physical state of a subject change, the sensors collect body dynamic signals generated from the changes; the body dynamic signals generated from heartbeat after being processed by an analog, amplification and filter circuit and the body dynamic signals generated from changes of the physical state are output to the FPGA respectively through A / D (Analog / Digital) conversion circuits; the FPGA sends the body dynamic signals to the DSP to perform body dynamic signal processing by selectingone or multiple paths sensors, so as to calculate the heart rate and judge the physical state, and obtained data are fed back to the FPGA; and the FPGA sends the data to a monitoring center workstation by externally connecting a serial port with a communication module according to the information fed back by the DSP. The device provided by the invention can complete real-time, quick and accurate acquisition of multi-path signals to obtain physiological information of human body, and is combined with the wearing technology to realize long-term dynamic monitoring and identification of physiological information.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a heart rate and body state monitoring device. Background technique [0002] The 21st century is called the "silver hair century", and the wave of aging is rolling around the world. According to the survey and statistics of China Population Information Research Center, in 2000, the population over 60 years old accounted for 10.31%, and the population over 65 years old accounted for 7.17% of the total population. Measured by international standards, China has entered an aging society, and In the next few decades, its aging trend will become more and more obvious. In addition, with the development of social economy, the change of living style, the miniaturization of family structure, and the acceleration of population flow, the number of children decreases, and the empty nest rate of elderly families is constantly increasing. Therefore, it is becoming more and more prominent to s...

Problems solved by technology

However, clinically used heart and lung function detection methods require medical staff to use professional equipment to operate, and most of them need to attach sensors to designated parts of the human body, which will make the human body feel uncomfortable and inconvenient for daily monitoring of heart and lung function
