    • [Object] To provide a peristaltic pump in which blockage of a liquid flow route can be detected without connecting a new separate member to the liquid flow route. [Solution] A peristaltic pump includes a mounting concave section 8a on which a peristaltically-actuated tube 1a connected to an arterial blood circuit 1 is mountable; a roller 10 which compresses the peristaltically-actuated tube 1a mounted on the mounting concave section 8a in a radial direction and causes the peristaltically-actuated tube 1a to be peristaltically actuated in a longitudinal direction such that a liquid therein is flowable in the arterial blood circuit 1; a load sensor 18 that is able to detect displacement of the peristaltically-actuated tube 1a mounted on the mounting concave section 8a in the radial direction; and blockage detecting means 19 that is able to detect a blockage of the arterial blood circuit 1 based on the displacement detected by the load sensor 18.
    • [目的]提供一种蠕动泵,其中可以检测到液体流动路径的阻塞,而不将新的分离的构件连接到液体流动路径。 [解决方案]蠕动泵包括安装凹部8a,其上安装有连接到动脉血回路1的蠕动致动管1a; 辊10,其沿径向压缩安装在安装凹部8a上的蠕动驱动管1a,并使蠕动驱动管1a沿长度方向蠕动致动,使得其中的液体在动脉血回路中流动 1; 负载传感器18,能够检测在径向上安装在安装凹部8a上的蠕动驱动管1a的位移; 以及能够基于由负载传感器18检测到的位移来检测动脉血液回路1的阻塞的阻塞检测单元19。
