Patent ID: 8123715

Claim:
A peritoneal dialysis and hemodialysis hybrid-remedy planning method for use with a peritoneal dialysis and hemodialysis hybrid-remedy planning apparatus having a computation unit and an output unit, the computation unit performing a computation using data obtained from a dialysis patient and outputting results of the computation to the output unit, the peritoneal dialysis and hemodialysis hybrid-remedy planning method comprising causing the output unit to output, as an index indicating an effect of dialysis, a parameter obtained as a result of the computation by the computation unit and to be shared by both peritoneal dialysis and hemodialysis, the parameter being a ratio M/C(0), where M is a removal amount of a solute for a fixed time period, and C(0) is a concentration of the solute in blood before the dialysis, and causing the computation unit to derive M and C(0) from at least one of a drained-fluid-volume curve and a D/P curve, causing the computation unit to obtain the at least one of the drained-fluid-volume curve and the D/P curve from results of computation using a Pyle-Popovich model and using a modified Powell method, and wherein M is obtained by a product of waste concentration in a drained fluid and a drained fluid volume as a value used for peritoneal dialysis, and by a product of clearance of a dialyzer and dialysis duration as a value used for hemodialysis, both the value used for peritoneal dialysis and the value used for hemodialysis being measured in a same dimension so as to achieve an integrated sum of values of M/C(0) planned to be achieved by peritoneal dialysis and hemodialysis for a fixed period of time.
