Claims

[Scope of utility model registration request]

(1) Built-in fixing member that fixes the ends of a large number of microporous hollow fiber membranes made of hydrophobic polymers while keeping them open;
The inside of the hollow fiber membrane and the fixing member are partitioned into a gas flow path and a contact chamber, a blood inlet and a blood outlet for flowing blood into the contact chamber, and a gas containing oxygen supplied to the gas flow path. A first container has a gas inlet for removing air bubbles from the hollow fiber membrane, and a deaeration port for discharging air bubbles released into the blood in the contact chamber from the hollow fiber membrane, and a blood inlet and a blood outlet, into which the blood is introduced. a second container having a heat exchange means for the blood that has been collected, and a blood inlet of the first container and a blood outlet of the second container, or a blood outlet of the first container and a blood outlet of the first container. A hollow fiber membrane oxygenator which is directly connected to a blood inlet of a second container.

(2) The heat exchange means includes a plurality of tubular bodies for flowing a heat exchange medium inside the second container, which are substantially perpendicular to the direction from the blood inlet to the blood outlet of the second container. A hollow fiber membrane oxygenator according to claim 1, which is arranged as follows.
