PROBLEM TO BE SOLVED: To provide an analyte information acquisition device for performing scan by moving a liquid tank, capable of suppressing liquid level variation of a matching liquid which is caused by movement of the liquid tank, and suppressing quality deterioration of acquired analyte information.SOLUTION: An analyte information acquisition device comprises: a support part comprising a support plane 201 for supporting a subject, and an insertion hole 202 provided on the support plane and into which an analyte 101 which is a part of the subject is inserted downward in a vertical direction an annular bank 403 protruding downward in the vertical direction from the support part, and arranged so as to surround the insertion hole 202 and a movement probe unit comprising a probe 402 for receiving an acoustic wave which is transmitted from inside of the analyte and a scanning base 410 in which the probe 402 is arranged and which relatively moves to the insertion hole 202, and being arranged below the annular bank 403 in the vertical direction. The annular bank 403 and the movement probe unit regulate a matching material storage container 400 for storing an acoustic matching material 401 in an integrated state.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】液槽を移動させることで走査を行う被検体情報取得装置において、液槽の移動に伴って発生するマッチング液の液位変動を抑制し、取得する被検体情報の品質低下を抑制することができる被検体情報取得装置を提供する。【解決手段】被検体情報取得装置は、被検者を支持する支持面201と、支持面に設けられ被検者の一部である被検体101が鉛直方向下方に挿入される挿入口202と、を有する支持部と、支持部から鉛直方向下方に突出し、挿入口202を囲むように配置された環状堤403と、被検体内から伝搬する音響波を受信する探触子402と、探触子402が配置され、挿入口202に対して相対的に移動する走査ベース410と、を含み、環状堤403の鉛直方向下方に配置された移動探触子ユニットと、を有し、環状堤403と移動探触子ユニットとが、音響整合材401を一体的に収納する整合材収納容器400を規定する。【選択図】図1
