Description

technical field [0001] The invention belongs to the technical field of biomedical engineering, and in particular relates to a body-pulmonary blood circulation simulation system for testing artificial organs. Background technique [0002] Organ transplantation becomes the only means of treatment when the human organ is diseased and cannot be cured by drugs, surgery, etc. However, the number of organs available worldwide is far lower than the number of patients in need of organ transplantation. With the continuous progress of biomedical engineering, the development of artificial organs such as artificial heart and artificial heart-lung instrument has solved this problem. However, in the research and development process, the performance verification of artificial organs only relies on animal experiments for a long period of time, and the repeatability is poor, which will delay the research and development process. Therefore, the development of an extracorporeal blood circulatio...
