An artificial lung is provided that includes a plurality of porous hollow fiber membranes for gas exchange comprising a hydrophobic polymer material, wherein the hollow fiber membranes have inner surfaces forming lumens and outer surfaces, and wherein at least one of the inner surfaces or the outer surfaces is coated with a polymer-containing solution that has a surface tension of 40 to 55 dyn/cm and that contains a solvent and a polymer having a structural unit represented by Formula (I): wherein in Formula (I), Rrepresents a hydrogen atom or a methyl group, Rrepresents an alkylene group having 1 to 4 carbon atoms, and Rrepresents an alkyl group having 1 to 4 carbon atoms.

Artificial lung and method for manufacturing artificial lung

A liquid collection bag is used as a part of an extracorporeal circuit and is connected via a tube to a storage container containing a priming solution. The collection container collects the priming solution from the storage container by a pressure differential between the pressure inside the collection container and the pressure inside the storage container. The liquid collection container is a flexible bag body having a partition part dividing the inside of the bag body into a first space and a second space. In addition, a communication part communicates the first space with the second space.
