PROBLEM TO BE SOLVED: To provide a finger type infusion pump capable of telling the abnormality of the flow rate caused by the falling or the like of a pump to a medical worker such as a nurse or the like.SOLUTION: In such a state that an infusion tube T is mounted on a pump body 1 and a door is closed, the interval between the tip 21b of a finger 21 present at the most retreat position and the pressure plate 24 of the door 12 is detected by a distance sensor 6. In a case that the detected value of the interval is larger than a predetermined allowance value, the abnormality of the flow rate is reported. By this constitution, in a case that the interval between the tip 21b of the finger 21 of a pump mechanism and the pressure plate 24 in a closed door state becomes large due to a fall of the infusion pump or the like and a sudden abnormal rise of the sending amount (infusion flow rate) of the infusion by the pump mechanism is produced, the abnormality of the flow rate of the infusion can be reported to the medical worker such as the nurse or the like and the infusion in a state that the flow rate of the infusion is in an abnormal state can be prevented.COPYRIGHT: (C)2013,JPO&INPIT【課題】ポンプ落下等に起因する流量異常を、看護師等の医療従事者に知らせることが可能なフィンガ式の輸液ポンプを提供する。【解決手段】ポンプ本体1に輸液チューブTを装着し、扉を閉鎖した状態で、最後退位置にあるフィンガ21の先端21bと扉12の押圧板24との間の間隔を距離センサ6によって検出する。そして、その間隔の検出値が所定の許容値よりも大きい場合に、流量異常を報知する。このような構成により、輸液ポンプの落下等によって、扉を閉鎖した状態でのポンプ機構のフィンガ21の先端21bと押圧板24との間の間隔が大きくなり、ポンプ機構にて輸液を送り出す量(輸液流量)が急上昇する異常が発生した場合には、その流量異常を、看護師等の医療従事者に知らせることが可能となり、輸液流量が異常な状態での輸液を防止することができる。【選択図】図11
