Abstract
A multi-path perfusion control method and apparatus for injection pump, an injection pump and a storage medium, wherein the method includes: controlling the injection pump to open at least one perfusion channel when an ablation task is triggered, so as to execute a perfusion operation through an opened perfusion channel according to a preset initial flow rate; acquiring temperatures of a plurality of positions of an ablation object in real time by a plurality of temperature acquisition apparatuses; and controlling the injection pump to open or close some or all of the perfusion channels and/or adjust flow rates of some or all of the perfusion channels according to a real-time change in the temperatures of the plurality of positions. Operation delay or operation errors caused by manual determination can be reduced, and the timeliness, accuracy and pertinence of liquid perfusion during executing the ablation task can also be improved.
