Manufacturing method of artificial organ, hollow fiber membrane, and dialyzer of hollow fiber membrane type

摘要

The present invention provides a manufacturing method of an artificial organ comprising a material having a solubility parameter delta of not more than 13 (cal/cm<3>)<1/2>, and a microporous membrane having a portion coated with a fat-soluble modifier. The manufacturing method is composed of the steps of: filling micropores of the body fluid treatment membrane with a filling solution, which has no or little solubility with a fat-soluble modifier solution; and coating a portion of the body fluid treatment membrane with the fat-soluble modifier by contacting the fat-soluble modifier solution. This may allow only necessary portion to be coated with the fat-soluble modifier so that a smaller amount of the fat-soluble modifier may be employed.
