Document Type and Number:

Japanese Patent JP3875231

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a manufacturing method for a liquid treatment module capable of enhancing the retention amount of a hydrophilic agent and effectively manufacturing.
SOLUTION: A casing 2 having a membrane substrate inside is set in a state that a blood discharge port 13 and a blood injection port 15 are positioned in the vertical direction. A treatment liquid containing the hydrophilic agent at a prescribed concentration is injected in the casing 2 through the blood injection port 15 in a state that a dialysis liquid injection port 8 and a dialysis fluid discharge port 9 are closed by plug members 38. Then, the dialysis liquid injection port 8 and the dialysis liquid discharge port 9 are opened, and the blood injection port 15 is closed. In this state, a compressed gas is introduced from the blood discharge port 13, thereby the treatment liquid is moved.
