[0063] Further, the preparation method of the liquid guide 10b includes the following steps: making the degradable material into a thin film of the required shape, then injecting antifreeze injection preparation to form the liquid guide part 120, and then using the hot injection molding method of the mold to form the liquid guide part 120. 120 is integrated on the first substrate 110b. It can be understood that, in the process of thermal injection molding using a mold, the injection hole formed when injecting the antifreeze injection formulation is fused with the first substrate 110b to form a sealed film.
[0064] Furthermore, each liquid guiding part 120 is in a zigzag shape; further, each liquid guiding part 120 is in the shape of a cone; furthermore, each liquid guiding part has a height of 1.5-2 mm, a bottom surface diameter of 50-200 μm, and adjacent The distance between the two liquid guides 120 is 500 μm to 1000 μm, and the amount of antifreeze injection preparation fi...
