<p>PROBLEM TO BE SOLVED: To reduce the load on a patient and continuously, accurately and directly measure the blood pressure by oppressing the midway of the artery by a cuff belt according to the maxim pressure measurement signal, releasing the oppression in the case of no change in the measurement value. and restoring the blood pump to the driving state in a stable period. SOLUTION: When the measurement value of a manometer 40 exceeds a tolerance of the stable pressure value in a stable period during a dialysis, the primary control part of a control means 50 restores a blood pump 20 to its driving state at the starting time and, when the measurement value at this time exceeds the tolerance of the initial pressure value, it outputs the maximum pressure measurement signal, while in unchanged time, it restores the blood pump 20 to the driving state in the sable period. The secondary control part of the control means 50 oppresses the midway of the artery 2 with a cuff 31 according to the maximum pressure measurement signal from the primary control part, and when the measurement value at this time exceeds the tolerance of the maximum pressure value, it instructs emission of an alarm, while in unchanged time, the oppression in the midway of the artery 2 is released so that the blood pump 20 is restored to the driving state in the stable period.</p> |
