The purpose of the present invention is to provide a medical pump configured such that when a low flow rate operation is performed after the administration of a drug solution has been completed, there is no misunderstanding that the administration of the drug solution is incomplete. This medical pump control method makes it possible to determine that a blockage has occurred when the internal pressure of a fluid infusion tube is equal to or above a set value, and comprises: a low flow rate step (11) in which, after the administration of a drug solution to a patient has been completed, a low flow rate operation is performed in which the drug solution is transferred at a low flow rate as a means of preventing the formation of a thrombus a blockage pressure-reducing step (14) in which the pressure in the fluid infusion tube is reduced by operating a drive motor in reverse when it has been determined that there is a blockage (12) during the low flow rate step (11) and a stopping step (15) in which the drive motor is stopped after operating in reverse. In the stopping step (15), the drive motor is stopped (15-4) when the cumulative quantity of solution that has been transferred reaches a value that is equal to or slightly above the scheduled dose of the drug solution.Lobjet de la présente invention est de pourvoir à une pompe à usage médical conçue de façon que, quand une opération à faible débit est effectuée après que ladministration dune solution médicamenteuse est terminée, il ny ait pas de malentendu sur le fait que ladministration de la solution médicamenteuse est incomplète. Ce procédé de commande de pompe à usage médical permet de déterminer quune obstruction sest produite quand la pression interne dun tube de perfusion de fluide est égale ou supérieure à une valeur de consigne, et comprend : une étape à faible débit (11) où, après que ladministration dune solution médicamenteuse à un patient est terminée, une opération à faible débit est effectuée au cours de laq
