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.
