When the power switch 3 is turned on, the operation is started, and then it is determined whether or not the pressure switch 4 is turned on [step ST (hereinafter referred to as ST) 1]. When the user turns on the pressurizing switch 4 for measurement, the determination in ST1 is YES, the pump 13 is turned on (ST2), and pressurization to the cuff 5 is started. Then, it is determined whether or not the cuff pressure has reached the target pressure value (ST3). Until the cuff pressure reaches the target value, the pump 13 is kept on and pressurization is continued. When the cuff pressure reaches the pressurization target value, the determination in ST3 is YES, and the pump 13 is turned off at this time (ST
4) The pressurization is stopped and the cuff 5 is in the depressurization process. Then, the blood pressure measuring operation is started (ST5). This blood pressure measurement method is, for example, by digital processing, detecting the pulse wave amplitude in sequence and measuring the relationship between the pulse wave amplitude sequence and the cuff pressure. Specifically, if the measurement is performed using a well-known algorithm, good. Next, it is determined whether or not the blood pressures of the systolic blood pressure and the diastolic blood pressure have been determined, that is, whether or not the measurement has been completed (ST6), and the blood pressure measurement process is continued until the measurement is completed. When the measurement is completed, the living body temperature sensor 18 or the environment temperature sensor 19
The living body temperature or the environmental temperature is detected (ST7). These temperatures may be detected before blood pressure measurement.

てもよい。By the way, when the room temperature drops, the body feels cold,
Correspondingly, peripheral blood vessels contract, which is known to increase peripheral arterial resistance and increase blood pressure.
For example, as shown in FIG. 5, it can be seen that both the systolic blood pressure (SYS) and the diastolic blood pressure (DIA) change especially in the case of the finger with respect to the change in temperature. For example, Y = X−K (T−T 1 ) is used to correct this relationship in advance for correction, and after the determination in ST8 that the detected temperature is within the predetermined range is YES, the measured blood pressure value is corrected by this formula (ST9). ). In the above equation, K and T 1 are constants, in particular, T 1 is a reference temperature inside the room, and the blood pressure value is calculated with reference to the reference temperature T 1 . Here when environmental or biological temperature at the time of measurement is T is corrected measured value by the temperature difference between the reference temperature (T-T 1). That is, the temperature T and the blood pressure determination value X are entered in the above equation to obtain the corrected blood pressure value Y. The above equation is
In some cases, Y = X−K / (T−T 1 ), Y = X {1
+ K (T-T 1 )} may be used. Further, instead of the formula, a conversion table for correction may be stored in the memory 16.

Therefore, it is determined in ST8 whether the detected temperature is within the predetermined range or not, and the detected temperature is within the predetermined range in ST8. If not, normal measurement is impossible, and the alarm device 20 is sounded to give a warning that measurement is impossible (ST11). Then, in ST12, rapid evacuation is performed and the measurement is completed. However, within the predetermined range,
Using the above formula of the memory 16, the measured blood pressure is corrected from the detected temperature and the blood pressure determination value (ST9), and the corrected systolic blood pressure and diastolic blood pressure are displayed (ST10),
The exhaust valve 14 rapidly evacuates (ST12), and the measurement is also completed.
