The invention discloses a minitype bionic bracket reactor which comprises an oxygen-transfer silica gel wrapper, more than one three-dimensional porous bracket and an oxygen-transfer silica gel sealing port; the three-dimensional porous bracket is arranged in a polyglycolic acid or polylacti-co-glycolic acid wrapper; and two ends of the oxygen-transfer silica gel wrapper is sealed by an oxygen-transfer silica gel pipe. The minitype bionic bracket reactor has the advantages that the bracket greatly simplifies the structure and operation of a common biological reactor, farthest stimulates an in-vitro microenvironment of a cultured cell, obviously promotes growth and metabolism of the cultured cell, maintains long-term biological function of the cultured cell, can be widely applied to various cell cultivations, in particular to a primary cell, and is also very suitable for research of drug metabolism and filtration.
