  • Method of cleaning and qualifying a dialysis filter and machine for same
    Patent number: 7481931
    Abstract: The invention relates to a method and a machine for cleaning and qualifying a dialysis filter, which can be used to monitor changes in the filter over the course of the use life thereof while guaranteeing a high degree of safety in relation to possible contamination by blood residues. The inventive machine (10) comprises three treatment stations (11) which are independent from one another and which are used to regenerate simultaneously three dialysis filters (100). Each of the stations (11) rinses a dirty filter using a cleaning liquid and each station comprises a cleaning unit consisting of two distinct liquid transfer circuits. Two drains (17a, 17b), which are connected at each end of the blood compartment of the filter (100), are used to drain the contaminated liquid and the blood residues directly into drain containers (18a, 18b). The different cycles of the machine are controlled by way of a keyboard (19), which is associated with a display screen (20), and are managed automatically by a computer.
