PROBLEM TO BE SOLVED: To provide a mechanism to reduce a feeling of discomfort that overflowed matching liquid gives to a person to be examined in an acoustic wave reception device for receiving an acoustic wave.SOLUTION: An acoustic wave reception device includes: a support base 108 having a support part 108a for supporting a person to be examined, which is provided with an insertion port through which a subject, which is a part of the person to be examined, can be inserted a holding member connected to the support part at a position overlapping with the insertion port, which holds the subject and includes a recess 109a where subject side matching liquid is stored a liquid tank that can store probe side matching liquid to a liquid level that it is acoustically connected at least with the holding member 109 and a probe 103 disposed in the liquid tank so as to come in contact with the probe side matching liquid, which receives an acoustic wave propagating from the subject through the holding member and the probe side matching liquid, and converts it into an electric signal. The acoustic wave reception device includes a flow channel 120 for causing the subject side matching liquid 112 overflowed from the recess to flow to the liquid tank.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】音響波を受信する音響波受信装置において、流出したマッチング液が被検者に与える不快感を低減する機構を提供する。【解決手段】被検者を支持する支持部108aを有し、被検者の一部である被検体を挿入可能な挿入口が設けられた支持台108と、挿入口に重なる位置において支持部に接続され、被検体を保持するとともに被検体側マッチング液が貯留される凹部109aを有する保持部材と、探触子側マッチング液を少なくとも保持部材109と音響的に結合する液位まで貯留可能な液槽と、探触子側マッチング液に接するように液槽に配置され保持部材と探触子側マッチング液を介して被検体から伝搬する音響波を受信し電気信号に変換する探触子103と、を有し、凹部から流出した被検体側マッチング液112を液槽に流すための流路120を備えることを特徴とする音響波受信装置を用いる。【選択図】図1
