求翻译：物质交换器作为该系统的核心元件是根据血液透析器和人工膜肺氧合器的原理设计制作。它包括两套中空纤维半透膜集束，组织培养液从中空纤维半透膜外流过，新鲜培养液和气体则分别从两个半透膜集束的纤维间通过。是什么意思？

Material exchanger as a core component of the system is based on blood dialysis and artificial membrane oxygenation principle of design. It includes two sets of semi-permeable membrane of hollow fiber bundles, tissue culture from which the fluid outflow of air fiber semi-permeable membrane, respectively from two fresh culture medium and gas cluster between the fiber through a semipermeable membrane.
