Abstract: A stirring device for facilitating dialysis includes a housing, an axle with a first end portion extending out of the housing and a second end portion extending into the housing, a sprocket connected to the second end portion of the axle, a motor unit provided inside the housing, a circular cam plate mounted eccentrically on and being rotatably driven by a driving shaft of the motor unit, and a cam follower having a curved edge provided with gear teeth which mesh with the sprocket. The cam follower is formed with a cam groove to receive the cam plate. Rotation of the cam plate inside the cam groove causes reciprocating left and right movement of the cam follower to bring about reciprocating clockwise and counterclockwise rotation of the sprocket and the axle. A dialysate chamber confines a receiving space to receive a volume of solvent. The dialysate chamber is provided on top of the housing and is formed with an axially extending tubular sleeve. A sample tube holder is provided inside the dialysate chamber and has a shaft portion that extends into the tubular sleeve. The shaft portion is connected to the first end portion of the axle and has an upper end provided with a tube support portion to hold analytical test tubes.

Abstract translation: 用于促进透析的搅拌装置包括壳体，具有从壳体延伸出的第一端部的轴和延伸到壳体中的第二端部，连接到轴的第二端部的链轮，设置在轴内的马达单元 壳体，偏心地安装并由马达单元的驱动轴旋转驱动的圆形凸轮板，以及具有设置有与链轮啮合的齿轮齿的弯曲边缘的凸轮从动件。 凸轮从动件形成有用于接收凸轮板的凸轮槽。 凸轮槽内的凸轮盘的旋转引起凸轮从动件的往复运动，左右运动，从而使链轮和轴的顺时针和逆时针往复运动。 透析液室限制接收空间以容纳一定量的溶剂。 透析液室设置在壳体的顶部，并且形成有轴向延伸的管状套筒。 样品管保持器设置在透析液室内部，并且具有延伸到管状套筒中的轴部分。 轴部分连接到轴的第一端部，并且具有设置有用于保持分析试管的管支撑部分的上端。
