Therefore, regular blood pressure measurement is an essential element for safe treatment. ing. Traditionally, blood pressure is measured by staff such as nurses and doctors, and doctors judge and determine medication during treatment, extracorporeal blood volume, ultrafiltration rate, etc. based on the measured blood pressure. The treatment is performed while preventing a decrease in blood pressure during treatment.

大きく、問題であった。As a blood pressure measuring method, an auscultation method and an oscillometric method in which Korotkoff sound is detected by a stethoscope are generally well known, but a blood pressure meter based on the auscultation method or the oscillometric method is used for a patient's arm or finger. Since it is necessary to attach a cuff to and to apply pressure, the series of operations is a little complicated,
Moreover, since it is necessary to measure frequently depending on the symptom of the patient, much labor is required and the burden on the patient is large. Therefore, in order to simplify the complicated operation, attempts have recently been made to improve the workability by incorporating a fully automatic blood pressure monitor into a dialysis machine. However, these general sphygmomanometers can only measure intermittently and cannot continuously measure blood, so that it is not possible to cope with a sudden change in pathology during dialysis treatment. About 30 to 90 for measurement
It has the drawback of taking seconds. Therefore, recently, some devices have been developed which can continuously measure blood pressure and can judge the blood pressure tendency from the continuously measured blood pressure. However, all of these devices are expensive and complicated to operate, and it is necessary to apply pressure through a cuff wrapped around an arm or finger when measuring blood pressure, and thus long-term treatment is required. The dialysis treatment, which requires urine, is a problem because it imposes a heavy physical and mental burden on the patient.

The present invention has been achieved by focusing on the fact that the phase difference of the volume pulse wave is also linearly correlated. That is, the present invention relates to an electrocardiographic potential detecting means for detecting an electrocardiographic potential and a photoelectric volume detecting means for detecting a volume pulse wave, and the positions of the electrocardiographic potential and the volume pulse wave detected by the electrocardiographic potential detecting means and the photoelectric volume detecting means. A blood pressure correlation value monitoring device comprising a blood pressure correlation value calculation means for continuously calculating the blood pressure correlation value from the phase difference is connected to the hemodialysis device so that the blood pressure during dialysis treatment is continuously monitored. It is a hemodialysis device with a blood pressure monitoring function.

Since the pulse wave transmission velocity is inversely proportional to the phase difference between the cardiac potential and the volume pulse wave, and the pulse wave transmission velocity is directly proportional to the blood pressure, the cardiac potential calculated by the blood pressure correlation value calculation means And the phase difference of the volume pulse wave are continuously calculated as a blood pressure value that is inversely proportional to the actual blood pressure, that is, a blood pressure correlation value. Therefore, by monitoring this blood pressure correlation value,
The blood pressure of the patient during dialysis treatment can be continuously monitored.

い。FIG. 5 is a diagram showing the relationship between the cardiac potential CG and the volume pulse wave PG. The starting point SEP of the PG and the maximum amplitude MA.
P can be clearly identified, and the systolic blood pressure Pbs and the average blood pressure Pbm can be determined corresponding to each point. Further, the apex R of the R wave of the CG substantially coincides with the start point of the ventricular contraction. Therefore, the pulse wave transmission velocity generated during contraction and dilation of the heart is inversely proportional to the phase difference between the cardiac potential and the volume pulse wave, and the pulse wave transmission velocity is directly proportional to the blood pressure. The phase difference RSEP between R and SEP can be calculated as a blood pressure correlation value Sbs with Pbs, and the phase difference RMAP between R and MAP can be calculated as a blood pressure correlation value Sbm with Pbm. The diastolic blood pressure Pbd cannot be directly obtained from the PG change pattern, but the pulse wave constant α obtained from the measured PG waveform is used.
Using v, the equation: Pbm-Pbd = αv (Pbs-Pbm) /
It can be calculated from (1-α v), and since the blood pressure and the blood pressure correlation value are inversely proportional, the blood pressure correlation value Sbd with Pbd is
Is the expression: Sbd = SbmSbs (αv −1) / (αv Sbm−S
It can be calculated from bs). Although it is possible to monitor the blood pressure using these blood pressure correlation values Sbd, Sbm, and Sbs, it is preferable to use these blood pressure correlation values after converting them into blood pressure by the separately provided blood pressure conversion means 21. ..

The blood pressure is converted into blood pressure corresponding to the above-mentioned maximum blood pressure Pbs, average blood pressure Pbm, and minimum blood pressure Pbd. This converted blood pressure is sent to the information writing / reading means 6, is written in the storage medium 8 set in the information writing / reading means 6, and is hemodialyzed together with the information input from the information input means 7 and written. It is transmitted to the water removal amount calculation unit 11 of the device 1 and used as a parameter for controlling the flow rate of dialysate and blood.
