Abstract

PURPOSE:To provide a continuous blood pressure measuring system which enables the relieving of pains of a person to be inspected. CONSTITUTION:This system is made up of a blood pressure measuring section 20A and a blood pressure change monitoring section 20B, which is provided with pulse sensors 10 and 11 to be mounted on different two parts of a human body. A time difference of pulses to be detected with the pulse sensors 10 and 11 is calculated with a CPU8 to calculate a variation in a blood pressure from a change of the time difference. Only when the variation in the blood pressure exceeds a specified value, the blood pressure measuring section 20A is operated to perform a measurement of the blood pressure.

[0006] Generally, continuous blood pressure monitoring is performed in order to know the blood pressure value that has fluctuated greatly. Therefore, in this continuous blood pressure monitoring device, the propagation time (velocity) of a pulse wave or the like is always detected, the blood pressure fluctuation value is determined from this propagation time, etc., and it is further determined whether this blood pressure fluctuation value has reached a predetermined value. If the blood pressure fluctuation is large when the blood pressure is above a certain level, the operation of the blood pressure measuring device is started and the blood pressure is measured there. Therefore, measurement is performed only when blood pressure fluctuations are large, and there is compression of the body by the cuff, but when fluctuations are small otherwise, the blood pressure measurement device is not operated, so the pain to the subject can be reduced and unnecessary measurement can be performed. You can avoid repetition.

The CPU 8 is known that the time difference between the pulse waves of the two pulse wave sensors 10 and 11 (the speed at which the pulse wave propagates between the two parts) is substantially proportional to the blood pressure value as shown in FIG. There is. That is, if the blood pressure value does not change, the time difference does not change, but if the blood pressure value changes significantly, the time difference t also changes. In the example of FIG. 3, when the blood pressure value changes from BP 1 to BP 2 , the time difference also changes from t 1 to t 2 .

When the subject is wearing the cuff 1 and the pulse wave sensors 10 and 11, the start switch is turned on to start the operation, and the blood pressure measuring unit 20A measures the initial value blood pressure (step ST1). In this blood pressure measurement, the pressurizing pump 4 is turned on to pressurize the pressure of the cuff 1 to a predetermined target value, then the pressurizing pump 4 is turned off, and the exhaust valve 6 discharges at a very low speed. The detected cuff pressure is continuously taken in, the cuff static pressure and the pulse wave component are separated by the CPU 8, the cuff pressure and the pulse wave amplitude are obtained in a time-sequential manner, and the systolic blood pressure is determined by the vibration method using a well-known algorithm. The systolic blood pressure is determined, and the systolic blood pressure and diastolic blood pressure are displayed on the display 9 as initial values and stored in the memory of the CPU 8 (step ST2).

According to the present invention, the continuous monitoring of blood pressure fluctuations uses the unloaded and unconstrained PWV method (pulse wave velocity method), and the blood pressure is measured only when a predetermined blood pressure fluctuation occurs. Therefore, continuous blood pressure monitoring can be performed without causing pain to the subject. In addition, blood pressure can be monitored very finely for each beat. Further, since the blood pressure is measured only when a predetermined blood pressure fluctuation occurs, unnecessary blood pressure measurement is not performed. Furthermore, by using the short-time blood pressure measurement method using a single pulse wave for blood pressure measurement, there is an effect that continuous blood pressure monitoring can be performed with a low load (almost no load).
