Claims

[Scope of utility model registration request]

A large number of bundled hollow fibers are housed in a cylinder with a protruding blood flow tube on the side, both ends of which are fixed with potting material, and a gas flow tube in the center. A cap-like lid body provided is fitted to both ends or one end of the cylinder body, and a fluid inlet provided on the side of the cylinder body is inserted between both ends of the hollow fibers in a converged state within the cylinder body. A hollow fiber membrane type, characterized in that a flexible membrane is attached that forms a cylindrical fluid chamber between the inner peripheral surface of the cylinder body and the outer peripheral surface of the focused hollow fibers by introducing fluid from the mouth. Artificial lung.
