PROBLEM TO BE SOLVED: To provide a syringe pump which can reliably detect whether a syringe is properly mounted or not regardless of the type of the syringe.SOLUTION: A syringe pump 60 includes a syringe mounting part 70 and a detection part 71. The syringe mounting part includes a lower end surface of an outer cylinder receiving part 90 and a flange part pressing part 91 for sandwiching a flange part of a syringe 50 from both sides and holding it. The detection part detects whether the syringe is properly mounted on the syringe mounting part or not by using a difference between a gap between the outer cylinder receiving part and the flange part pressing part when the flange part is held by the outer cylinder receiving part and the flange part pressing part and a gap between the lower end surface of the outer cylinder receiving part and the flange part pressing part when the flange part is not held by the lower end surface of the outer cylinder receiving part and the flange part pressing part.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】シリンジの種類によらず、シリンジが正しく装着されたか否かを確実に検出できるシリンジポンプを提供する。【解決手段】シリンジポンプ60は、シリンジ装着部70と検出部71を有している。シリンジ装着部は、シリンジ50の鍔部を両側から挟んで保持する外筒受け部90の下端面及び鍔部押さえ部91を有している。検出部は、鍔部が外筒受け部及び鍔部押さえ部に保持されたときの当該外筒受け部と鍔部押さえ部の間の隙間と、鍔部が外筒受け部の下端面及び鍔部押さえ部に保持されなかったときの外筒受け部の下端面と鍔部押さえ部の隙間との違いを利用して、シリンジ装着部にシリンジが正しく装着されているか否かを検出する。【選択図】図1
