Description

  The present invention relates to an electronic blood pressure monitor module and an electronic blood pressure monitor.

  Blood pressure is one index for analyzing cardiovascular diseases. Analyzing the risk of cardiovascular disease based on blood pressure is effective in preventing cardiovascular diseases such as stroke, heart failure and myocardial infarction. In particular, early morning hypertension, in which blood pressure rises in the early morning, is related to heart disease and stroke. Furthermore, it has been found that, among early morning hypertension, a symptom of a sudden rise in blood pressure between 1 hour and 1.5 hours after waking up, called morning surge, has a causal relationship with stroke.

  Thus, grasping the correlation between time (lifestyle) and blood pressure change is useful for risk analysis of cardiovascular diseases. Therefore, it has become important to continuously measure blood pressure over a long period of time.

  In addition, recent research results have shown that home blood pressure measured at home is more effective in preventing, diagnosing, and treating cardiovascular diseases than blood pressure measured during hospitals and health examinations (advanced blood pressure). ing. Along with this, electronic blood pressure monitors for home use have become widespread, and movements have started to use home blood pressure values for diagnosis.

  In general, the structure of an electronic sphygmomanometer includes a pump for controlling the pressure in the cuff attached to the measurement site, a valve, a pipe (tube), a substrate for controlling the electronic sphygmomanometer, a display unit for displaying blood pressure values, and an electronic sphygmomanometer. It is comprised from the operation part which inputs operation, such as a power supply ON / OFF operation and a measurement start, and the housing which accommodates these apparatuses etc. in the inside (for example, following patent document 1, 2).

  The blood pressure calculation unit 112 detects pulse wave amplitude information based on a frequency signal input from the first oscillation circuit 331 or the second oscillation circuit 332 (this frequency signal indicates a pressure information signal), and the detected pulse wave amplitude information Based on the oscillometric method, systolic blood pressure and diastolic blood pressure are calculated, and the pulse rate per predetermined time is calculated based on the detected pulse wave amplitude information.

  Specifically, in the process of gradually increasing (or reducing) the cuff pressure to a predetermined value by the pressure adjusting unit 111, the pulse wave amplitude is based on the cuff pressure input from the first oscillation circuit 331 or the second oscillation circuit 332. Information is detected, and the systolic blood pressure and diastolic blood pressure of the measurement subject are calculated based on the detected pulse wave amplitude information. Conventionally known methods can be applied to blood pressure calculation and pulse calculation according to the oscillometric method by the blood pressure calculation unit 112.

  The sensor abnormality detection unit 113 receives the frequency signals output from the first oscillation circuit 331 and the second oscillation circuit 332, and analyzes the input signals to thereby detect abnormalities in the first pressure sensor 321 and the second pressure sensor 322.

Further, the output data from the sensor abnormality detection unit 113 is input, and the input data (pressure sensor abnormality detection result) is stored in a predetermined storage area of the memory 43. The recording unit 114 outputs measurement data from a predetermined storage area of the memory 43 to the display processing unit 115 based on the operation of the memory switch 41C of the operation unit 41.

  The display processing unit 115 inputs the given data, converts it into a displayable format, and displays it on the display unit 40.

  FIG. 3 shows only a portion of the peripheral circuit of the CPU 100 that directly inputs and outputs with the CPU 100.

(Processing procedure for blood pressure measurement)
With reference to FIG. 4, the blood pressure measurement processing procedure according to the present embodiment will be described. The flowchart showing the processing procedure of FIG. 4 is stored in advance in the memory 42 as a program, and the blood pressure measurement processing of FIG. 4 is realized when the CPU 100 executes a read command of the program from the memory 42.

  First, when the measurement subject operates (presses) the measurement / stop switch 41A (step ST1), the CPU 100 initializes a working memory (not shown) (ST2).

  Subsequently, 0 mmHg of the first pressure sensor 321 and the second pressure sensor 322 is adjusted (ST3).

  Here, the person to be measured wraps and wears the cuff 20 around the measurement site (upper arm) of the person to be measured. After the cuff 20 is wound, when the measurement subject operates (presses) the measurement / stop switch 41A (step ST4), the pressure adjustment unit 111 outputs a control signal to the pump drive circuit 53 and the valve drive circuit 54. The pump drive circuit 53 and the valve drive circuit 54 drive the pump 511 after closing the valve 512 based on the control signal. Thereby, the cuff pressure is gradually increased to a predetermined pressure (steps ST5 and ST6).

  After pressurization to a predetermined pressure (≧ predetermined pressurization value in step ST6), the pressure adjustment unit 111 outputs a control signal to the pump drive circuit 53 and the valve drive circuit 54. The pump drive circuit 53 and the valve drive circuit 54 stop the pump 511 based on the control signal, and then control the valve 512 to open gradually. Thereby, the cuff pressure is gradually reduced (step ST7).

  In this depressurization process, the blood pressure calculation unit 112 is based on the frequency signal output from the first oscillation circuit 331 or the second oscillation circuit 332, that is, based on the cuff pressure signal detected by the first pressure sensor 321 or the second pressure sensor 322. Based on the detected pulse wave amplitude information, a predetermined calculation is performed on the detected pulse wave amplitude information. By this calculation, systolic blood pressure and diastolic blood pressure are calculated (steps ST8 and ST9). The pulse wave amplitude information represents the volume change component of the artery at the measurement site and is included in the detected cuff pressure signal. In the calculation of the blood pressure by the blood pressure calculation unit 112, an operation according to the change in the characteristics of the pressure sensor is performed. The blood pressure measurement is not limited to the decompression process, and may be performed in the pressurization process (step ST5).

  When the systolic blood pressure and the diastolic blood pressure are calculated and determined (YES in step ST9), the pressure adjustment unit 111 fully opens the valve 512 via the valve drive circuit 54 and rapidly exhausts the air in the cuff 20 (step ST10). ).

  The blood pressure data calculated by the blood pressure calculation unit 112 is output to the display processing unit 115 and the recording unit 114. The display processing unit 115 inputs blood pressure data and displays it on the display unit 40 (step ST11). Further, the recording unit 114 inputs blood pressure data, associates the time data input from the timer 45, and stores it in a predetermined storage area of the memory 43 (step ST12).

  The blood pressure calculation unit 112 can also calculate the pulse rate based on the detected pulse wave amplitude information. The calculated pulse rate is displayed on the display unit 40 by the display processing unit 115 and stored in the memory 43 in association with the blood pressure data by the recording unit 114.

  The operation so far is the same as that of a conventional electronic blood pressure monitor. In the conventional electronic sphygmomanometer, since the user cannot determine whether the pressure sensor that is the most important element for calculating blood pressure is normal or abnormal, the blood pressure measurement value is a normal value (for example, If it is significantly different from the previous day's measurement value (measured value at the hospital, etc.) (for example, if it is more than 10mmHg), it is unclear whether it is due to physiological information of the living body or because the pressure sensor has failed There was a sense of anxiety.

  Therefore, the electronic sphygmomanometer 1 according to the present embodiment includes the first pressure sensor 321 and the second pressure sensor 322, and calculates the average value of the cuff pressure detected by these pressure sensors as the blood pressure. Thereby, even if the detection accuracy of one of the pressure sensors varies due to secular change, the reliability of the blood pressure measurement value can be improved by calculating the average value.
