Title:
CLOSED CIRCULATION SYSTEM TEST APPARATUS FOR BLOOD PURIFICATION DEVICE USING WHOLE BLOOD
Document Type and Number:
WIPO Patent Application WO/2021/201181
Kind Code:
A1
Abstract:
Provided is a closed circulation system test apparatus that independently sets the amount of a liquid such as a dialysate for a blood purification device, facilitates management of operations of multiple pumps, and is capable of evaluating, under the condition where the water removal amount is increased, performance for removing wastes in blood and lifespan performance of membranes. The closed circulation system test apparatus according to the present invention performs a performance evaluation test on a blood purification device within a closed circuit not in contact with the atmosphere, with the blood purification device, a blood bag, and a replacement fluid container being set in the closed circulation system test apparatus. The closed circulation system test apparatus is characterized by comprising: a blood sending line for sending blood from the blood bag to the blood purification device via a blood pump; a blood returning line for sending blood exiting from the blood purification device to the blood bag via a resistance imparting means; a filtrate line for sending the filtrate exiting from a dialysate outlet of the blood purification device to the replacement fluid container via a filtrate pump; and a dialysate line for sending, via a dialysate pump, dialysate or replacement fluid from the replacement fluid container to a dialysate inlet of the blood purification device and/or to the blood returning line.
