Description
Technical Field
The utility model relates to an electronic circuit technical field, concretely relates to sphygmomanometer and sphygmomanometer system.
Background
Due to the influences of factors such as living environment, living habits, working pressure and the like, people suffering from cardiovascular diseases show a low-age trend, blood pressure is one of important parameters of human bodies, and if the blood pressure of people can be measured frequently, the health condition of people can be monitored, so that health problems can be found earlier, and a better treatment effect can be obtained.
At present, methods for measuring blood pressure mainly include korotkoff sound method and oscillometric method. The Korotkoff sound method is used for measuring the blood pressure by pressing the sleeve to squeeze the blood vessel, so that the blood flow is completely blocked, and simultaneously, the stethoscope is used for listening different sounds of the pulse to judge the values of the systolic pressure and the diastolic pressure. However, there are some inherent disadvantages to measuring blood pressure by the korotkoff sound method: one is that it is difficult to determine diastolic blood pressure; secondly, the values of the systolic pressure and the diastolic pressure are judged according to the vision and the hearing of people, which have subjective factors, and general people can hardly measure the blood pressure unless professional doctors. Various Korotkoff sound method electronic blood pressure meters have been developed in the past, and the automatic detection of the blood pressure is tried to be realized, but the blood pressure meters are quickly found to not only fail to overcome the inherent defects of the Korotkoff sound method blood pressure measurement, but also have the defects of large error, poor repeatability and the like. Therefore, most of the current non-destructive blood pressure automatic detection instruments abroad adopt an oscillography method.
Oscillometric blood pressure measurement estimates the blood pressure from the relationship between pulse wave amplitude and cuff pressure. Due to the hemodynamic effect of the heart beat, pressure fluctuations synchronized with the heart beat, i.e. the pulse wave, will be superimposed under the cuff pressure. When the pressure in the oversleeve is far higher than the systolic pressure, the pulse wave disappears; as the pressure in the cuff decreases, a pulse begins to appear; when the pressure in the oversleeve is reduced to be lower than the systolic pressure from higher than the systolic pressure, the pulse wave can be suddenly increased, and the amplitude of the pulse wave reaches the maximum value when the pressure reaches the average pressure; and then decays as the pressure within the cuff decreases.
However, the conventional oscillometric blood pressure monitor cannot sensitively and accurately detect the pulse wave of the human body due to the pressure sensor, so that the measurement error of the blood pressure monitor is large. Therefore, the prior art lacks a blood pressure meter with high sensitivity and accurate measurement.

Specifically, the operation module may control the operation state thereof by controlling when the power supply module supplies power to the central control module, wherein the operation module includes a switch module that controls the connection or disconnection of the power supply module and the central control module.
When the central control module obtains electric energy from the power supply module through the operation module to start working, the central control module can output an inflation electric signal to the inflation and deflation module, so that the inflation and deflation module inflates the air bag structure in the oversleeve at a preset inflation speed, meanwhile, the pressure sensor also monitors the pressure generated by pulse pulsation in real time and the pressure exerted on a human body after the air bag structure in the oversleeve is inflated, converts the pressure generated by the pulse pulsation into a pulse electric signal to be output to the central control module, and converts the pressure exerted on the human body after the air bag structure in the oversleeve is inflated into a pressure electric signal to be output to the central control module.

The central control module can store the pulse electric signal and the pressure electric signal generated in the deflation process after receiving the pulse electric signal and the pressure electric signal generated in the deflation process, and can control the inflation and deflation module to stop working according to the pressure electric signal. The central control module analyzes the pulse electric signals and the pressure electric signals generated in the inflating process and the deflating process and calculates to obtain the blood pressure value and/or the heart rate value of the measurer.
In addition, because the control device of the sphygmomanometer in the second embodiment further includes the alarm module and the wireless transceiver module, after the central control module calculates the blood pressure value and/or the heart rate value of the measurer, it is further necessary to further determine whether the calculated blood pressure value and/or the heart rate value is within a normal range, that is, the calculated blood pressure value and/or the heart rate value of the measurer is correspondingly compared with the normal blood pressure range and/or the heart rate range, and if the calculated blood pressure value and/or the heart rate value is not within the normal range, the central control module outputs an alarm control signal to the alarm module, so that the alarm module sends an alarm signal to alarm, otherwise, the alarm module does not operate. The wireless transceiver module can send the blood pressure value and/or the heart rate value of the measurer calculated by the central control module to the terminal device to inform a user at the terminal device side, such as a guardian and/or an attending doctor of the measurer, so that the user at the terminal device side can conveniently know the blood pressure and/or the heart rate condition of the measurer.
