The utility model relates to an isolated organ perfusion device includes liquid storage pot, centrifugal pump, membrane lung, first peristaltic pump, leucocyte filter, hemodialyzer and waste liquid bag. The liquid inlet end of the first peristaltic pump is communicated with the liquid storage tank through a pipeline, and the liquid outlet end of the first peristaltic pump is communicated with the liquid inlet end of the hemodialyzer through a pipeline. The liquid outlet end of the hemodialyzer is communicated with the liquid storage tank through a pipeline, and the waste discharge end of the hemodialyzer is communicated with the waste liquid bag through a pipeline. The liquid storage tank, the first peristaltic pump and the hemodialyzer form a filtration circulation auxiliary path, and the leukocyte filter is arranged on the filtration circulation auxiliary path. When the leukocyte filter leads to the jam because of long-time work, the leukocyte filter can lead to the filtration circulation auxiliary road to take place to block up, and can not lead to the perfusion circulation main road to take place to block up, and the perfusion circulation main road still can continue to work this moment, can continuously play the guard action to isolated organ to in time change filtration circulation auxiliary road on the leukocyte filter can. |
