Zusammenfassung:To provide a technique that can detect only air bubbles having sizes equal to or larger than a predetermined size in an infusion tube.SOLUTION: An infusion pump detector (11) for detecting air bubbles in an infusion tube (20) for sending an infusion solution to a living body comprises an arrangement part (111) in which a tube (20) is arranged, at least one first electrode (112) and a second electrode (113) provided adjacently to the arrangement part (111), and a detecting part (114) for detecting a change in capacitance via the tube (20) by using the first electrode (112) and the second electrode (113).SELECTED DRAWING: Figure 2 【課題】輸液チューブ内の所定以上の大きさの気泡のみを検知できる技術を提供する。【解決手段】輸液剤を生体に送るための輸液用チューブ(20)内の気泡を検知するための輸液ポンプ用検知器(11)は、チューブ(20)が配置される配置部(111)と、配置部(111)に隣接して設けられた、少なくとも1つの第1の電極(112)及び第2の電極(113)と、第1の電極(112)及び第2の電極(113)を用いて、チューブ(20)を介した静電容量の変化を検出する検出部(114)と、を備えている。【選択図】図2
