Stirring device for facilitating dialysis

A stirring device for facilitating dialysis, comprising:

• a housing;
• a mechanical driving assembly including:
• an axle having a first end portion extending out of said housing and a second end portion extending into said housing;
• a sprocket connected to said second end portion of said axle;
• a motor unit provided inside said housing and having a driving shaft;
• a circular cam plate mounted eccentrically on and being rotatably driven by said driving shaft;
• and a cam follower having a curved edge provided with gear teeth which mesh with said sprocket, said cam follower being formed with a cam groove to receive said cam plate, and rotation of said cam plate inside said cam groove causing reciprocating left and right movement of said cam follower to bring about reciprocating clockwise and counterclockwise rotation of said sprocket and said axle;
• a dialysate chamber formed as a hollow cylinder that confines a receiving space to receive a volume of solvent, said dialysate chamber being provided on top of said housing and being formed with an axially extending tubular sleeve;
• and
• a sample tube holder provided inside said dialysate chamber and having a shaft portion that extends into said tubular sleeve of said dialysate chamber, said shaft portion being connected to said first end portion of said axle and having an upper end provided with a tube support portion that is formed with a plurality of angularly spaced tube receiving holes for holding analytical test tubes.
