PROBLEM TO BE SOLVED: To provide a drip infusion monitoring device and drip infusion monitoring system, capable of accurately detecting liquid drips even when the liquid drips are small, an infusion solution is close to transparency, or a drip infusion cylinder is inclined by the movement of a patient.SOLUTION: The drip infusion monitoring device detects the liquid drips falling inside a light transmissive drip infusion cylinder and calculates the number and interval of the falling drips. The monitoring device includes: a light emitting element and a light receiving element, which are arranged on the same side surface of the drip infusion cylinder an amplification circuit for amplifying a signal from the light receiving element a rectifying circuit for rectifying the amplified signal a central calculation circuit for calculating the signal a display means for displaying the calculation result an alarm means for issuing alarm in response to the calculation result and an interface for connecting the central calculation circuit to a host system. Thus, even when the liquid drips are small, the infusion solution is close to transparency, or the drip infusion cylinder is inclined by the movement of the patient, the liquid drips are accurately detected.COPYRIGHT: (C)2012,JPO&INPIT【課題】液滴が小さい場合や輸液が透明に近い場合、或いは患者が動いて点滴筒が傾いた場合であっても適確に液滴を検出することのできる点滴モニタ装置および点滴監視システムを提供することにある。【解決手段】光透過性の点滴筒内を落下する液滴を検出し、滴下数、滴下間隔を算出する点滴モニタ装置であって、前記点滴筒の同一側面に配置された発光素子および受光素子と、受光素子からの信号を増幅する増幅回路と、増幅された信号を整流する整流回路と、信号を演算する中央演算回路と、演算結果を表示する表示手段と、演算結果に応じて警報を発する警報手段と、中央演算回路と上位システムを接続するインターフェイスとを備えたので、液滴が小さい場合や輸液が透明に近い場合、或いは患者が動いて点滴筒が傾いた場合であっても適確に液滴を検出することができる。【選択図】図1
