The invention discloses a medical digital gastrointestinal machine simulation operation training simulated person and a manufacturing method thereof. The front surface of the simulated person is madeof a skin color silica gel material; the back and side parts are made of a transparent silica gel material; internal organs are made of a transparent silica gel material; the proportion between the size of the simulated human body and the size of real human body is 1:1; transparent internal organs comprise a transparent esophagus, a transparent stomach, a transparent duodenum and a transparent intestinal tract; the transparent intestinal tract comprises a large intestine, a small intestine and a rectum; the organs are manufactured according to the size of the normal human body organs and are assembled according to a dissected structure. The simulated person according to the invention is advantageous in that the appearance of the simulated person is similar with the human body contour; thebody material is equivalent with the human body tissue; and the internal tissue and organ are simulated with the real members; students can directly finish digital gastrointestinal machine simulationoperation training teaching in a laboratory without going to a hospital; not only are high visuality and high reality sense realized, but also multiple experiments can be performed simultaneously, thereby improving a teaching effect.
