Laboratory PDX model establishment auxiliary system and control method thereof

The invention belongs to the technical field of animal model building, and discloses a laboratory PDX model building auxiliary system and a control method thereof.The laboratory PDX model building auxiliary system is characterized in that a tumor cell suspension is added into a closed container in the laboratory PDX model building auxiliary system; micropores are distributed on the periphery of the outer side of the closed container and similar to a sieve, immune cells of normal experimental animals outside the container can be prevented from entering the container to attack human tumor cells, meanwhile, nutrient substances and cytokines can enter the container through the micropores to be in contact with the tumor cells, and the closed container is round in appearance and can be opened and closed. The laboratory PDX model building auxiliary system is simple in structure and low in cost, and compared with a traditional PDX model, the system can better simulate the biological environment of tumor cells in the
