<p>PROBLEM TO BE SOLVED: To surely and precisely mensurate a blood re-circulation amount without receiving external influences. SOLUTION: This hemorephoretic mechanism includes a light source 2 which casts a near infrared ray to a blood circuit 1 on the artery side, a light amount mensuration means (an absorbence meter) 3 to mensurate the luminous energy which has permeated the blood circuit 1, a controller 7, and a rephoretic amount calculating means (an arithmetic and logic unit) 6 which calculates a hemorephoretic amount from a period of time since the changing of a water- removing amount to the change of the luminous energy having permeated when the water-removing amount is changed in steps during a dialysis by the control device 7, and the variation amount of the permeated luminous energy.</p> |
