Venous oxygenation device to enrich the blood with oxygen, the oxygenation device has a fiber bundle, this fiber bundle is connected to the gas discharge means by the second connecting portion connected to the gas supply means by first connecting portion respectively and twisting the fiber bundles by the, to rotate with each other with respect to the second connecting portion of the fibers of the first connection portion of the fiber about the longitudinal axis of the oxygenator in use. In intravenous oxygenator for insertion into a vein further, can be moved along the longitudinal axis of the oxygenator connected to the second fiber holding portion and the respective first connection part, the fiber holding section of the longitudinal axis of the oxygenator and is mounted such that it can rotate around each other. Such sequences to allow gas exchange particularly efficient.酸素で血液を富化する静脈酸素化装置で、この酸素化装置は繊維束を有し、この繊維束はそれぞれ第一接続部によりガス供給手段と接続し第二接続部によりガス排出手段と接続し、使用時に酸素化装置の縦軸の周りに繊維の第一接続部を繊維の第二接続部に対して互いに回転することにより繊維束を捻る。更に静脈に挿入する静脈酸素化装置において、接続部がそれぞれ第一及び第二繊維保持部と接続し酸素化装置の縦軸にそって移動でき、繊維保持部が酸素化装置の縦軸方向の周りを互いに回転出来るように取り付けられている。このような配列は特に効率的なガス交換を可能にする。
