In-vitro simulation system for anti-biofilm of central venous catheter

The utility model relates to the technical field of biological evaluation of medical instruments, in particular to a central venous catheter anti-biofilm in-vitro simulation system, which comprises a culture medium storage tank, a pumping device, a biofilm forming device and a waste liquid tank which are sequentially connected, sealing plugs are arranged at the left end and the right end of the cavity, and flow guide pipes penetrating left and right are arranged on the sealing plugs; the two ends of the test sample abut against the inner side walls of the sealing plugs respectively, or the two ends of the test sample are communicated with the flow guide pipes respectively. According to the in-vitro simulation system provided by the utility model, by arranging the sealing plugs with the flow guide pipes, when the in-vitro simulation system is used, the two ends of the test sample are respectively propped against the inner side walls of the two sealing plugs or are respectively communicated with the flow guide
