大きく、問題であった。As a method of measuring blood pressure, auscultation and oscillometric methods for detecting Korotkoff sounds with a stethoscope are well known. Blood pressure monitors based on auscultation and oscillometric methods are generally used for measuring a patient's arm or finger. Since it is necessary to attach a cuff and apply pressure, the series of operations is a little complicated,
In addition, frequent measurements are required depending on the condition of the patient, which requires a lot of labor and a heavy burden on the patient. Therefore, in order to simplify the complicated operation, in recent years, attempts have been made to incorporate a fully automatic sphygmomanometer into a dialysis machine to improve workability. However, these general sphygmomanometers can only intermittently measure blood and cannot measure blood continuously, so at present it is not possible to cope with a sudden change in the condition during dialysis treatment. About 30 to 90 for measurement
It has the disadvantage of requiring seconds of time. Therefore, recently, there have been developed some devices capable of continuously measuring blood pressure and judging a blood pressure tendency from the continuously measured blood pressure. However, all of these devices are expensive and complicated to operate, and when measuring blood pressure, it is necessary to apply pressure through a cuff wrapped around an arm or finger, which results in prolonged treatment. Dialysis treatment, which requires dialysis, is a problem because the physical and mental burden on the patient is large.

As a result, the transmission speed of a pulse wave generated at the time of contraction and dilation of the heart is linearly correlated with the blood pressure. Attention has been paid to the fact that there is also a linear correlation with the phase difference of the volume pulse wave, and the present invention has been reached. That is, the present invention provides a cardiac potential detecting means for detecting a cardiac potential, a photoelectric volume detecting means for detecting a plethysmogram, and a position of the cardiac potential and the plethysmogram detected by the cardiac 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 a blood pressure correlation value from the phase difference, is connected to the hemodialysis device so as to continuously monitor the blood pressure during the dialysis treatment. This is a hemodialysis device with a blood pressure monitoring function.

る。According to the above arrangement, the cardiac potential is detected by the cardiac potential detecting means, and the plethysmogram is detected by the photoelectric volume detecting means. Since the transmission speed of the pulse wave is inversely proportional to the phase difference between the cardiac potential and the volume pulse wave, and the transmission speed of the pulse wave is directly proportional to the blood pressure, the cardiac potential obtained by the blood pressure correlation value calculating means is obtained. Is continuously calculated as a blood pressure value 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 the 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 point MA are shown in FIG.
P can be clearly identified, and the systolic blood pressure Pbs and the average blood pressure Pbm can be determined corresponding to each point. In addition, the vertex R of the CG R-wave substantially coincides with the start of the ventricular contraction. Therefore, since the transmission speed of the pulse wave generated at the time of contraction and expansion of the heart is inversely proportional to the phase difference between the cardiac potential and the volume pulse wave, and the transmission speed of the pulse wave is directly proportional to the blood pressure, the blood pressure correlation value calculating means 5 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. Further, 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.
Using v, the formula: Pbm−Pbd = αv (Pbs−Pbm) /
The blood pressure and the blood pressure correlation value are inversely proportional to each other, so that the blood pressure correlation value Sbd with Pbd is obtained.
Is given by the formula: Sbd = SbmSbs (αv −1) / (αv Sbm−S
bs). Although it is possible to monitor the blood pressure using these blood pressure correlation values Sbd, Sbm, and Sbs, it is preferable to convert these blood pressure correlation values into blood pressure by a separately provided blood pressure conversion means 21 and use it. .

The blood pressure is converted into a blood pressure corresponding to the systolic blood pressure Pbs, the average blood pressure Pbm, and the diastolic blood pressure Pbd. This converted blood pressure is sent to the information writing / reading means 6 and is written in the storage medium 8 set in the information writing / reading means 6, and is also subjected to hemodialysis together with the information inputted and written from the information input means 7.
