PROBLEM TO BE SOLVED: To provide a device easily and accurately inspecting an operation situation (particularly the accuracy of a liquid feed amount, and the warning operation in time of closing pressure generation) on a housing side of a syringe pump or calibration of closing detection by one device.SOLUTION: This inspection calibration machine for the syringe pump includes: a guide part 3 tubularly formed in imitation of an outer tube of a syringe a detection part 31 a fixed slit plate 37 provided on the inner face of the detection part a plunger 13 incorporated in the guide part movably in the axial direction a movement slit plate 29 fixed to a tip part in the axial direction of the plunger a closing spring 25 stored inside the guide part, and restricting the forward movement in the axial direction by abutment on the plunger a computer part 47 and a display part 48 provided in the computer part. The inspection calibration machine for the syringe pump calculates the movement distance of the plunger by use of a change of interference fringes by slits, and generates a closing pressure by the closing spring, and displays the operation situation (the liquid feed amount and the generation of the closing pressure) of the housing on a display part.COPYRIGHT: (C)2013,JPO&INPIT【課題】シリンジポンプのハウジング側の作動状況(特に、送液量の精度、閉塞圧発生時の警告動作)や閉塞検出の校正を、一つの装置で容易且つ正確に点検する装置の提供。【解決手段】シリンジの外筒に擬して筒状に形成されたガイド部3と、検出部31と、検出部の内面に設けられた固定スリット板37と、ガイド部内に軸方向移動自在に組み込まれた押子13と、押子の軸方向先端部に固定された移動スリット板29と、ガイド部内に収容され、押子への当接により軸方向先方への移動を規制する閉塞ばね25と、コンピュータ部47と、コンピュータ部に設けられた表示部48とを備える。スリットによる干渉縞の変化を利用して押子の移動距離を算出すると共に、閉塞ばねにより閉塞圧の発生を作り出して、ハウジングの作動状況(送液量と閉塞圧の発生)を表示部に表示させる。【選択図】 図4
