Method for calculating filter clogging factor and bed-side system

摘要

Method for calculating a clogging factor of a filter composed of hollow-fiber membrane, which has a blood inflow portion 32a and a blood outflow portion 32b, by passing a blood, the method including the steps of measuring at least two pressure selected from the group consisting of a pressure (Pa) in said blood inflow portion, a pressure (Pv) in said blood outflow portion, a filtering pressure (Pf1) in said blood inflow portion, and a filtering pressure (Pf2) in said blood outflow portion and calculating a filter clogging factor in vertical direction and/or a filter clogging factor in lateral direction using at least two of the measured pressures, flow rate information, biometric information (viscosity information and so on), and structure information.
