Embodiment 1
[0072] Example 1: Preparation of bionic jejunum
[0073] (1) Prepare clay: knead the soft clay repeatedly to obtain soft clay with good ductility;
[0074] (2) Jejunum mold pressing: Put the kneaded soft clay into the precise human jejunum anatomical model of the medical gastroenterology department, squeeze it hard, remove the human jejunum anatomical model, and obtain the soft clay jejunum with the real internal physiological structure of the jejunum Mold, the diameter of the mold is 2cm, and the length is 25cm;
[0075] (3) Production of hollow fluff: Take a number of needles with a diameter of 0.5mm, stick them on each imprint on the above mold, poke a small hole with a diameter of 1mm and a depth of 5mm, and the needles will continue to remain inside the mold
[0076] (4) Baking and molding of the jejunum mold: put the jejunum mold into an oven and bake at 140°C for 15 minutes to solidify the jejunum mold and cool naturally to obtain a bionic jejunum mold;
