Claims (3)
- 発光素子と受光素子とを含む滴落検知器を含み、点滴筒内を滴落する点滴が通過する水平面位置に対向して前記発光素子と前記受光素子とが配置されており、前記発光素子と前記受光素子とが作る複数の光軸が前記点滴筒内の前記水平面をスキャニングする機能を持ち、前記点滴が前記発光素子と前記受光素子間を通過するあいだに1回以上のスキャンニングを行うことが可能であり、
前記滴落検知器は、前記発光素子と前記受光素子とを、各々複数含み、
各スキャンニングにおいて、それぞれの素子を独立した組み合わせで順次受発光させて、前記受光素子が受けた各光軸の受光電圧を得、障害物を通過していない光軸を受光した受光素子から得られる受光電圧を基準として、前記基準よりも低い受光電圧の光軸がある場合は、前記低い受光電圧の光軸の存在をもって、点滴及び前記点滴が繋がった連続流を検知する、輸液ポンプ。 - 前記輸液ポンプは、点滴筒内に連続流が発生した場合に警報を発生する警報発生部を含む、請求項1に記載の輸液ポンプ。
- 請求項1又は2に記載の輸液ポンプを用いた点滴及び前記点滴が繋がった連続流の検出方法であって、
各スキャンニングにおいて、それぞれの素子を独立した組み合わせで順次受発光させて、前記受光素子が受けた各光軸の受光電圧を得、障害物を通過していない光軸を受光した受光素子から得られる受光電圧を基準として、前記基準よりも低い受光電圧の光軸がある場合は、前記低い受光電圧の光軸の存在をもって、点滴及び前記点滴が繋がった連続流を検知する、点滴及び前記点滴が繋がった連続流の検出方法。
