PROBLEM TO BE SOLVED: To provide a liquid infusion apparatus which includes liquid infusion tube compression means for simplifying and compactifying the structure of a door, which blocks the liquid infusion tube when the door opens, and which accurately detects whether the liquid infusion tube has been blocked during a liquid infusion process.SOLUTION: A liquid infusion apparatus comprises: a finger module provided in a main body such that the finger module can elastically retract from a liquid infusion tube 30 a tube clamp 50, in which two clamp bodies spaced apart from each other approach each other by means of restoring force of an elastic member upon opening a door 20 during infusion, so as to compress and block the liquid infusion tube and a tube blockage detection mechanism which detects whether the liquid infusion tube is blocked or expanded by an event, such as bending of a discharge side of the liquid infusion tube, which delivers medicinal liquid pumped by a liquid pump during infusion.COPYRIGHT: (C)2014,JPO&INPIT【課題】ドアの単純化、コンパクト化などを成す輸液チューブ圧迫手段を含み、ドアが開かれれば、輸液チューブが閉塞し、輸液中に輸液チューブが閉塞したかを正確に検出する輸液装置を提供する。【解決手段】本体に輸液チューブ30から弾力的に引っ込むことができるように設置されたフィンガーモジュール、輸液中にドア20を開けば、離隔した二つのクランプボディーが弾性部材の復元力によって接近して輸液チューブを圧搾する方式で輸液チューブを閉塞するチューブクランプ50、輸液中に輸液ポンプによる移送薬液を輸送する輸液チューブの排出側が折れるとかして輸液チューブが閉塞及び膨脹したかを検出するチューブ閉塞検出機構を含む、輸液装置を提供する。【選択図】図2
