The invention provides an ambulatory blood pressure monitoring system and a calibration method of a non-invasive continuous blood pressure measuring device. The ambulatory blood pressure monitoring system comprises a non-invasive continuous blood pressure measuring module, a cuff type blood pressure measurement module and a physiological signal acquisition module, and is characterized in that the non-invasive continuous blood pressure measuring module is used for collecting pulse wave signals of a user and sending the pulse wave signals to a server; the cuff type blood pressure measurement module is used for receiving a calibration instruction from the server, measuring the current blood pressure of the user and sending the current blood pressure to the server; the physiological signal acquisition module is used for acquiring physiological signals related to emotion and movement of the user and sending the physiological signals to the server; the server is used for calculating the non-invasive blood pressure of the user according to the received pulse wave signals, determining an emotion and motion mixed index according to the non-invasive blood pressure and the received physiological signals, determining a calibration moment according to the emotion and motion mixed index, and sending the calibration instruction to the cuff type blood pressure measurement module, and the server is used for calibrating the non-invasive continuous blood pressure measurement module according to the current blood pressure at the calibration moment.
Description
technical field [0001] The invention mainly relates to the field of medical instruments, in particular to a dynamic blood pressure monitoring system and a calibration method for a noninvasive continuous blood pressure measuring device. Background technique [0002] Hypertension is an independent risk factor for coronary artery disease, congestive heart failure, chronic kidney disease, and stroke, and it is also an important cause of increased cardiovascular events and overall mortality. The diagnosis of hypertension and the long-term monitoring of its therapeutic effect depend on accurate and repeatable blood pressure monitoring. Office Blood Pressure Monitoring (OBPM) has great limitations, such as non-standard operation of medical staff, subjective preference of the measurer for the measurement results, and blood pressure fluctuations caused by the white coat effect, etc., which will cause inaccurate measurement results. precise. In addition to OBPM, it also includes amb...
