The invention provides a visualized bionic digestion reactor for a stomach body and belongs to the field of bionic reactors. The visualized bionic digestion reactor comprises a first adaptor, a secondadaptor, reaction bottles, a latex bionic stomach, a sampling bottle and a constant-temperature circulating water groove, wherein the reaction bottles comprise a vertical straight-type reaction bottle, a spherical reaction bottle and a horizontal straight-type reaction bottle; the latex bionic stomach comprises a latex bionic stomach body, a latex bionic stomach antrum and a latex bionic pylorus,which are placed in the vertical straight-type reaction bottle, the spherical reaction bottle and the horizontal straight-type reaction bottle respectively; the constant-temperature circulating watergroove is connected with input pipes and output pipes on the reaction bottles through silica gel pipes; valves are connected with the middles of the silica gel pipes and are used for controlling thecirculating water flow. The visualized bionic digestion reactor for the stomach body, provided by the invention, is simple in structure, convenient to detach, good in sealing performance and strong invisibility, can be used for vividly simulating peristalsis of a human stomach and has good digestion simulation repeatability.
