1. Method for analysis of the pressure variation in a perfusion device,said perfusion device comprising a plurality of perfusion modules i each equipped with a pump to deliver a liquid to be perfused in a line i placed downstream from the pump as well as with means for measuring the pressure in the line i, at least one junction point enabling connection of at least one of the lines i with (a) at least another of the lines i or (b) at least one line from at least one unit external to the perfusion device, wherein said method comprises:

  • detecting, among lines i of modules i, a variation of pressure Pk in a line k of a module k, and determining, among modules i other than module k, an involvement of one or several modules j in this pressure variation, by an analytical process.
