| description | To provide an ultrasound measurement apparatus for use with an extracorporeal circulation apparatus to allow measurement of blood flow rate and density.SOLUTION: An ultrasound measurement apparatus 1A is used with an extracorporeal circulation apparatus 100A, and includes ultrasound transceivers 10A, 10B attached to a blood circuit 110, and a measurement circuit 20A for measuring blood flow rate and density. The measurement circuit 20A comprises: a transmitter 21; a receiver 22; a flow rate calculation unit 24A for calculating a blood flow rate based on a transmission signal transmitted by the transmitter 21 and a reception signal received by the receiver 22; and a density calculation unit 25 for calculating a blood density based on an attenuation degree of the reception signal amplitude with respect to the transmission signal amplitude.SELECTED DRAWING: Figure 1
【課題】体外循環装置に用いられ、血液の流量及び濃度を測定可能な超音波測定装置を提供すること。【解決手段】超音波測定装置１Ａは、体外循環装置１００Ａに用いられ、血液回路１１０に取り付けられる超音波送受波器１０Ａ、１０Ｂと、血液の流量及び濃度を測定する測定回路２０Ａと、を備え、測定回路２０Ａは、送信部２１と、受信部２２と、送信部２１により送信された送信信号及び受信部２２により受信された受信信号に基づいて血液流量を算出する流量算出部２４Ａと、送信信号の振幅に対する受信信号の振幅の減衰度合に基づいて血液濃度を算出する濃度算出部２５と、を備える。【選択図】図１ |
