Experimental animal solid organ tissue infarction dyeing fixing device

The utility model discloses a dyeing and fixing device for solid organ tissue infarction of an experimental animal. The dyeing device comprises a dyeing cylinder, a dyeing cylinder cover and a grid, the dyeing cylinder is brown or opaque, the dyeing cylinder cover is brown or opaque, the grid can be placed in the dyeing cylinder, and a filter screen is arranged on the lower portion of a hole in the grid. According to the utility model, tissue slices are placed on the filter screens in the holes of the grids; tTC staining, after dyeing, the whole grid is transferred to a paraformaldehyde solution for tissue fixation, the fixed tissue slice is clamped out of the grid for photographing or the grid (a transparent pore plate) can be directly placed under a dark background for photographing, inthe process, the slice does not need to be clamped repeatedly, damage to the tissue slice is reduced, and damage to the tissue slice is avoided. According to the utility model, the clamping frequencyof each piece of tissue ca
