| 摘要 |
The present invention relates to a method of circulating organo-biological liquids, preferably blood, wherein a liquid contained in a reservoir is released to a pressure (head) level below its original fluid pressure (head) level, thereafter raised periodically or in steps to a pressure (head) level above the original level, then transferred from such level to a reservoir positioned at a predetermined, relatively lower pressure (head) level, and thereupon drained to an outlet positioned approximately at the level of the original pressure (head) level. |
