< Topic >20 drop /ml transportation liquid sets and 60 drop /ml transportation liquid sets which are installed are automatically distinguished, the transportation liquid pump which prevents the configuration mistake of the operator is offered.Solutions20 drop /ml transportation liquid sets the drop opening inside the drop cylinder which is installed in 10 and 60 drop /ml transportation liquid sets 11 (the nozzle) from the fact that diameter differs respectively, putting drop opening 13,14 to drop cylinder rim, luminous element you installed 23 and light absorbent component 24 in the position where it opposes, light of the luminous element you made the distinction of transportation liquid set of 2 types possible by the fact that the light absorbent component measures a state where it shades by the drop opening inside the drop cylinder.< Choice figure >Drawing 3【課題】装着された20滴/ml輸液セットと60滴/ml輸液セットを自動判別し、操作者の設定ミスを防ぐ輸液ポンプを提供する。【解決手段】20滴/ml輸液セット10と60滴/ml輸液セット11に取り付けられている点滴筒内の点滴口(ノズル)の径がそれぞれ異なる事から、点滴筒外周に点滴口13,14を挟んで対向する位置に発光素子23と受光素子24を取り付け、発光素子の光が点滴筒内の点滴口により遮光される状態を受光素子が測定することで2種類の輸液セットの判別を可能とした。【選択図】図3
