PROBLEM TO BE SOLVED: To provide a blood flow adjusting device capable of adjusting a blood flow rate in a blood vessel to be a desired blood flow rate.SOLUTION: This blood flow adjusting device 1 is attached to a blood vessel 90 of a living body. The blood flow adjusting device 1 comprises: a cylindrical part surrounding the blood vessel 90; a pressing part 23 arranged inside the cylindrical part and capable of pressing the blood vessel 90; a blood flow measuring part 22 for measuring a blood flow rate of the blood vessel 90; and a control unit 10. The control unit 10 controls the pressing force of the pressing part 23 on the basis of a signal from the blood flow measuring part 22.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2019,JPO&INPIT【課題】血管の血流量を所望の血流量となるように調整可能な血流調整装置を提供する。【解決手段】この血流調整装置1は、生体の血管90に取り付けられる。血流調整装置1は、血管90の周囲を囲む筒状部と、筒状部の内部に配置されて血管90を押圧可能な押圧部23と、血管90の血流量を測定する血流量測定部22と、制御部10とを有する。制御部10は、血流量測定部22からの信号に基づいて、押圧部23の押圧力を制御する。【選択図】図5
