Abstract

The invention discloses an FPGA (field-programmable gate array)-based cardiovascular parameter non-invasive detection device and a control method, and relates to a non-invasive detection device of cardiovascular parameters of a human body and a control method; and the device comprises a signal acquisition module, a signal processing module, a control and analysis module, a blood oxygen saturationdegree detection module and a display screen, wherein the signal acquisition module is used for acquiring cardiovascular parameter signals through a pulse sensor, a pressure sensor and a photoelectric sensor; the signal processing module is used for transmitting the collected cardiovascular parameter signals; the control and analysis module adopts an FPGA control circuit for controlling acquisition of the cardiovascular parameter signals and analysis treatment of the cardiovascular parameter signals; the blood oxygen saturation degree detection module is used for getting a cardiovascular functional parameter value by calculating a waveform coefficient and heart rate of pulse waves; and the display screen is used for displaying operation steps and the measurement result of the device. The detection device is small in volume, convenient for carrying, simple for operation and low in cost, and can realize familialism of cardiovascular non-invasive detection.

Description

technical field [0001] The invention relates to the technical field of detection of human physiological parameters and research and development of electronic medical instruments, in particular to a non-invasive detection device and control method of cardiovascular parameters. Background technique [0002] Cardiovascular disease has become one of the high-profile health killers. According to the report of the World Health Organization, one of every three deaths is caused by cardiovascular disease. At present, in our country, the number of deaths caused by cardiovascular diseases is also increasing year by year, and the number of deaths caused by cardiovascular diseases is about 3 million every year. In this case, it is of great significance to detect the condition of cardiovascular disease in time to reduce the death of cardiovascular disease. Among the elderly, cardiovascular disease is one of the diseases with the highest morbidity and mortality. Therefore, if the prevale...
