PROBLEM TO BE SOLVED: To provide a liquid sending pump capable of sending a medicine of a proper sending amount not exceeding a prescribed upper limit determined in each kind of the medicine, when sending the medicine.SOLUTION: There is provided a liquid sending pump for sending a medicine, while simulating in vivo concentration of the sent medicine. In the liquid sending pump, an upper limit introduction flow rate of the medicine and an upper limit maintaining flow rate of the medicine are stored, and the upper limit of a sending amount of the medicine is switched to the upper limit introduction flow rate or the upper limit maintaining flow rate according to whether a vital observed value of a living body into which the medicine is sent reaches a target value or not.SELECTED DRAWING: Figure 1【課題】薬剤の送液時において、薬剤の種類ごとに定められている所定の上限値を超えない適切な送液量で薬剤を送液することが可能な送液ポンプの提供。【解決手段】送液した薬剤の生体内における濃度をシミュレートしながら、薬剤を送液する送液ポンプであって、薬剤の上限導入流量と薬剤の上限維持流量を記憶し、薬剤が送液された生体のバイタルの観測値が目標値に達しているか否かに応じて、薬剤の送液量の上限値を上限導入流量または上限維持流量に切り替える送液ポンプ。【選択図】図１
