METHOD OF INSPECTING STERILE FILTRATION OF HEMODIALYZER

摘要

PROBLEM TO BE SOLVED: To provide a means for inspecting the leakage of a sterile filter installed in a hemodialyzer. SOLUTION: A working function of an air introduction valve 22 is judged by measuring the variation of negative pressures through introducing the air from the air introduction valve 22 while the negative pressure is being given to a non-filtered dialytic chamber 20 of a sterilizing filter 18. The leakage is also judged by measuring the variation of negative pressures given to a sterilizing filter membrane 19 through introducing the air in the non-filtered dialytic chamber 20 while the negative pressure is being given to the sterilizing filter membrane 19.
