[Problem] To provide a medical pump and the like capable of precisely preventing the occurrence of a "suction phenomenon" in which a liquid medicine is suctioned from one medical pump side to another medical pump side. [Solution] This medical pump 10 is provided with: a liquid moving unit 30 capable of switching between a feed mode in which a liquid accommodated in a pipe section 11a is fed and the liquid inside the tube section is moved in the feeding direction, and a counterfeed mode in which the liquid is moved in a counterfeed direction an tube section inner condition information detection unit 17 for detecting tube section inner condition information of inside the tube section and a blockage determination unit 61 for generating blockage information of the tube section on the basis of the tube section inner condition information of the condition information detection unit. The medical pump 10 is configured such that the liquid moving unit changes to operation of the counterfeed mode on the basis of the blockage information of the blockage determination unit after operating in the feed mode, and has a counterfeed mode stop information generation unit 75 for generating counterfeed mode stop information, which is stop information for the counterfeed mode, on the basis of the tube section inner condition information.Le problème décrit par la présente invention est de fournir une pompe médicale et analogues capables de précisément prévenir lapparition dun "phénomène daspiration" dans lequel un médicament liquide est aspiré depuis un côté de pompe médicale vers un autre côté de la pompe médicale. La solution selon linvention porte sur la pompe médicale 10 étant pourvue : dune unité de déplacement de liquide 30 capable de commuter entre un mode dalimentation dans lequel un liquide contenu dans une section de tuyau 11a est introduit et le liquide à lintérieur de la section de tube est déplacé dans la direction dalimentation, et un mode de contre alimentation dans lequel
