Therefore, by injecting air into the measurement 3 in a stepwise manner and detecting the amount of air in the measurement 3 when it is detected that the measurement 3 is optimally wound, a small amount is measured. It becomes possible to detect.

If this is not detected (O at step S7), CP 4 counts the counter (step S g) and returns the process to step S 3. Then, the pump is driven again for time X (s) to supply a predetermined amount of air to 3. Steps S 3 S 5 are returned until step S 7 finds that measurement 3 meets the optimal conditions. A fixed amount of Qi is supplied to 3 and 8 in stages until the condition is satisfied.

- 008526 corresponds to 3 in step S3 to S7 and
- FIG. 9 is a diagram showing the amount of air supplied to 8, and a method for detecting the amount of air by using this diagram will be described.
- the amount of air supplied to 3 and 8, the horizontal axis represents the passage of time. Refer to 008 26 26 and stop pon 3 and drive 2 for time X ().
- the measurement position is thickened (size). If the optimum case is not detected there, the air supply is further repeated.
- step S the CP 4 compares the value stored in the counter with the stored value and detects the amount of the measurement position. If the amount is thick (size) or thin (size) (or in step S), the pressures of 3 and 8 are controlled accordingly (step S3). If it is quasi (size), skip step S3. Then, the blood pressure control corresponding to steps S4 to S2 is executed (step S5).
- step S When the amount corresponding to the measurement position is thickened (size) in step S, the CP 4 executes the control described below in step S3.
- 009 is a diagram showing the amount of air supplied to measurements 3 and 8 when the size corresponding to the measurement position is increased (size) in step S.
- the process proceeds to step S35.
- pressures 3 and 8 are started.
- the measurement position is thick, the compliance is large compared to the cases where the measurement position is normal and when the position AP is the same, the volume A is larger than that when the compliance is small. Therefore, measurement 3 has a larger volume under the same conditions than in cases where the arm thickness is normal and equal. Therefore, in order to reduce the compliance to the same extent as in the case where the measurement position is large, it is necessary to control the measurement 3 so that the tension is low.
- I kept the numbers 8 and 8 within a certain range (28). Similarly, when the position is thick (size),
- the 8 and 3 of 3 controls the pressure of compression 8 (28), since the measurement position is larger than when (size) is ().
- the difference value is not specifically limited to a specific value, but is preferably about twice.
- 0094 29 is the measurement when CP 4 does not do the above and Fig. 29 is the case
- the measurement position is the same as when the size is (size), then when the measurement position is thick (size), the amount of air in 3 is smaller than when it is the standard (size). Tonomo. As a result, the area of and becomes smaller, and the friction between and becomes smaller. As a result, measurement 3 is likely to expand.
- CP 4 performs the above control so that compression 8 is higher than when the measurement position is (size), and the amount of air in measurement 3 is small.
- step S if it is determined in step S that the measurement positions are in a large category, then in step S5, compression 8 is indicated by 28 for measurement 3 by 28.
- the control signal is output to the pump 36 so that the difference is increased.
- step S If the measurement position is fine (size) in step S, , S4, CP4 executes the control described below.
- the air amount in compliance 3 for each measurement position has the relationship shown in 3.
- 3 is the compliance
- the horizontal axis is
- the amount of air in 3 at time is obtained by integrating the compliance line up to that point. That is, when the measurement position is thin, the amount of air in 3 is smaller than when the thickness is standard.
- 0131 32 is a diagram for explaining the relationship between measurements 3 and 8 when the measurement position is small.
- the overlapping part is large compared to the standard (size). Therefore, the friction between and becomes large. As a result, the phenomenon that measurement 3 spreads outward can be suppressed.
- step S CP 4 measures in step S 5 if the measurement position is reduced in size (size).
- the control signal is output to the pump 26 to supply so that the air amount in 3 is the same as the air amount supplied to 3 when the size (size) is equal.
- the amount of air to be supplied can be obtained by measuring the amount of air in 3 for each unit, storing the amount of air corresponding to the unit in 4 etc., and reading the value.
- CP 4 supplies air as indicated by 3 to 33.
- 33 is a diagram showing the change in the amount of air in the measurement 3, in which the air was supplied stepwise to detect the above-mentioned size (() -X (3) ()-()), More air is supplied to measurement 3 so that it is closer to the amount of air supplied to 3 when the measurement position is at a normal level.
- the measurement position is thick (size) (Size) It can be combined with and when issued.
- Size Size
- the measurement position and compliance can be brought close to the standard compliance, regardless of whether the measurement position is thick or thin. Will be set in.
- the dotted line is the compliance shown in 23 above when the position is thick (size) and fine (size, C).
- the measurement position has the same width as that of the standard.
- the dotted line shows the width when the above control is not performed (the size and the width when the position and the position are fine (size, C), as shown in 24).
- the compliance becomes poor depending on the measurement position.
- the relationship with the product of 3 changes. Therefore, the wave obtained from measurement 3 is affected by the difference in product of 3 depending on the subject's position (mari), and the blood pressure measurement can be further improved.
