Composite infection model support and use method thereof

The invention belongs to the technical field of biology, and particularly relates to a composite infection model support and a use method thereof. The composite infection model support comprises a support body and an extending part, the support body is of a sheet structure, a through hole and a plurality of protruding parts are arranged on the support body, the through hole is located in the center of the support body, and the protruding parts are arranged around the through hole and extend towards one side of the support body; the extending part comprises a short rod and a cotton ball fixing part, a cotton ball is arranged on the cotton ball fixing part, and the cotton ball fixing part is connected to the edge of the support body through the short rod. A composite infected sepsis model (MIM) constructed based on the stent ensures that a cecum ligation part is not blocked by an intestinal tract, intestinal contents can be continuously released into an abdominal cavity through a perforation to form sustainable
