SPECIMEN ANALYSIS DEVICE, SPECIMEN ANALYSIS METHOD AND PROGRAM

To reduce a risk of accumulation of air bubbles in a flow path between a sampling nozzle and a fixed dispenser and formation of an air gap and reduce a risk of reduction in the analytical accuracy of a specimen.SOLUTION: A specimen analysis device includes a sampling nozzle, a fixed dispenser, a switching valve which switches the communication state of a flow path between the sampling nozzle and the fixed dispenser, a switching valve opening/closing instruction part and a fixed dispenser drive instruction part. The switching valve opening/closing instruction part controls the switching valve, the fixed dispenser drive instruction part performs a drawing instruction to the fixed dispenser in such a state that the connection between the sampling nozzle and the fixed dispenser in the flow path is shut down, the switching valve opening/closing instruction part controls the switching valve after the fixed dispenser draws liquid for discharge, the fixed dispenser drive instruction part performs a push-in instruction to the fixed dispenser in such a state that the sampling nozzle is connected to the fixed dispenser in the flow path, and the fixed dispenser pushes out the liquid for discharge to make it flow to the flow path, and discharges the liquid for discharge to the outside of the flow path.SELECTED DRAWING: Figure 7 【課題】サンプリングノズルと定注器との間の流路内で気泡が蓄積されてエアギャップが形成されるおそれを低減し、検体の分析精度が低下するおそれを低減する。【解決手段】検体分析装置は、サンプリングノズルと、定注器と、サンプリングノズルと定注器との間の流路の連通状態を切り替える切替弁と、切替弁開閉指示部と、定注器駆動指示部と、を備える。切替弁開閉指示部が切替弁を制御して、上記流路におけるサンプリングノズルと定注器との連通を遮断した状態で、定注器駆動指示部が定注器に対して引き込み指示を行って、定注器が内部に吐出用液体を引き込んだ後、切替弁開閉指示部が切替弁を制御して、上記流路においてサンプリングノズルと定注器とを連通させた状態で、定注器駆動指示部が定注器に対して押し込み指示を行って、定注器が吐出用液体を押し出して上記流路に流し、吐出用液体を上記流路の外部に排出させる。【選択図】図７
