Method and system for parameter control of ambulatory blood pressure

Abstract

The invention discloses a method and a system for parameter control of ambulatory blood pressure. The system comprises a processor unit, wherein the processor unit is connected with an acoustic sensor, a temperature sensor, an acceleration sensor and a blood pressure measurement module. The processor unit is also connected with a communication module, a display unit, a memory and a power module. The processor unit calculates according to the environmental information provided by the sound sensor, the temperature sensor and the acceleration sensor, and makes a judgment to control the working interval of the blood pressure measurement module, which transmits the measured blood pressure information to the processor unit. The invention focuses on some important external factors affecting humanblood pressure, respectively considers the influence on blood pressure measurement time for different factors, and then comprehensively considers all the factors to make a general judgment. At the same time, more sensors can be used to record the external environment conditions of blood pressure measurement, which can provide more information for doctors when they diagnose blood pressure.

Description

technical field [0001] The invention belongs to the technical field of medical devices, relates to the measurement of dynamic blood pressure, and relates to a parameter control method and system of dynamic blood pressure. Background technique [0002] Chronic cardiovascular and cerebrovascular diseases such as hypertension and diabetes are seriously threatening public health, among which the number of hypertensive patients is the largest, and the number of hypertensive people in my country has exceeded 270 million, bringing a heavy social burden. [0003] Hypertension is a chronic disease characterized by increased systemic arterial blood pressure (systolic and / or diastolic blood pressure) (systolic blood pressure ≥ 140 mm Hg, diastolic blood pressure ≥ 90 mm Hg). With the improvement of living standards, the average life expectancy has been greatly increased. At the same time, the increase in the pace of life and pressure has made the prevalence rate of hypertension increas...

Problems solved by technology

In this way, the limitation of the total number of measurements leads to a problem that is difficult to solve: in the process of rapid blood pressure fluctuations, it is necessary to understand the changes in blood pressure more carefully in time, which requires shorter measurement intervals; Timely observation of the patient's blood pressure changes, and the measurement interval needs to be as long as possible when the total number of measurements is constant. This pair of contradictions is difficult to satisfy at the same time.

[0009] Ordinary ambulatory blood pressure monitors use a doctor or nurse to set the measurement interval before wearing it. After the measurement starts, the blood pressure monitor will automatically measure according to the set time, and the measurement interval cannot be changed during the measurement process.

More complex setting strategies can set the time interval according to the time period, such as measuring once every half an hour during the day and every hour at night. This measurement interval is a fixed value and cannot be adjusted according to the patient's condition or the environment during the measurement process.

If the automatic measurement setting time is too short, it will cause discomfort in the patient's arm and seriously affect the patient's sleep at night

If the measurement interval is set too long, the patient's blood pressure information cannot be accurately obtained, and important blood pressure data may be missed

In addition, the movement of the patient will also cause some measurement failures, which will make the measurement data unable to meet the needs of diagnosis to a certain extent.
