Provided is a liquid delivery pump whereby, during drug liquid delivery, a drug can be delivered in an appropriate liquid delivery amount not exceeding a predetermined upper limit value established for each type of drug. A liquid delivery pump for delivering a drug while simulating the concentration of the delivered drug in a living body, the liquid delivery pump having: a calculation unit for calculating the concentration of the drug in the living body on the basis of the amount of the drug delivered a determination unit for determining whether the blood concentration of the drug calculated by the calculation unit or the effect-site concentration of the drug has reached a predetermined target concentration a storage unit for storing an upper-limit introduction flow rate of the drug, an upper-limit maintenance flow rate of the drug, and the target concentration a receiving unit for receiving inputting of the target concentration an upper-limit-value switching unit for switching the upper-limit value of the liquid delivery amount of the drug to the upper-limit introduction flow rate or the upper-limit maintenance flow rate in accordance with the result of determination by the determination unit and an adjustment unit for adjusting the liquid delivery amount of the drug in a range not exceeding the upper-limit value.La présente invention concerne une pompe de distribution de liquide, grâce à laquelle, lors de ladministration dun médicament liquide, un médicament peut être administré selon une quantité de distribution de liquide appropriée ne dépassant pas une valeur de limite supérieure prédéfinie, établie pour chaque type de médicament. Linvention concerne une pompe de distribution de liquide, destinée à ladministration dun médicament tout en simulant la concentration du médicament administré dans un corps vivant. La pompe de distribution de liquide comporte : une unité de calcul afin de calculer la concentration du médicament dans le corps vivant sur la base de la q
