ALARM/MONITOR SYSTEM OF VENOUS PRESSURE AND DIALYSIS FLUID PRESSURE IN HEMODIALYZER

摘要

An alarm/monitor system of venous pressure and dialysis fluid pressure which can start alarm/monitor operation of a hemodialyzer surely when a circulation movement is settled when the venous pressure and dialysis fluid pressure are monitored constantly. In a hemodialyzer constituted by connecting a dialyzer with an artery side blood circuit, a vein side blood circuit and a dialysis fluid supply/discharge line, venous pressure is detected from the vein side of a blood circuit after starting treatment and dialysis pressure is detected from a dialysis fluid line, detection value of at least any one of venous pressure and dialysis fluid pressure is obtained, and alarm/monitor operation is started when pressure variation width of the detection value at a predetermined time is settled within a set range.
