Patent ID: 7704224

Claim:
A peritoneal function testing method comprising: providing a computation unit; obtaining data of a dialysis patient using the computation unit; a 1st computation step of obtaining individual initial estimate values for (i) MTAC glc , MTAC un , and MTAC c by using the obtained data and a processor of the computation unit to compute a Pyle-Popovich model, and (ii) a L P S C /L P S ratio by using L P S C and L P S, where MTAC glc is an overall mass transfer-area coefficient for glucose, MTAC un is an overall mass transfer-area coefficient for urea nitrogen, MTAC c is an overall mass transfer-area coefficient for creatinine, L P S C is a permeability coefficient for cell pores, and L P S is an overall permeability coefficient; a 2nd computation step, following the 1st computation step, of using the computation unit to (i) obtain computation results by computing a Three-Pore Theory model using the individual initial estimate values for the MTAC glc , the MTAC un , the MTAC c , and the L P S C /L P S ratio obtained by the 1st computation step, and (ii) calculate an optimal solution of the computation results obtained by computing the Three-Pore Theory model, the optimal solution being calculated using a Genetic Algorithm; and using a MTAC un /MTAC c ratio, which is calculated using an optimal MTAC un and an optimal MTAC c determined using the optimal solution, as an index for a peritoneal function test.
