Abstract: A biomedical homogenizing device a seat, a rotational module, and at least one holding module. The seat has at least one driving wheel set, with each driving wheel set having at least one driving wheel. The rotational module is rotatably mounted on the seat and has a driving shaft and two rotating disks. The driving shaft extends through the at least one driving wheel set, the two rotating disks are respectively and firmly coupled to two ends of the driving shaft, and at least one driven wheel is rotatably mounted on at least one of the two rotating disks to be driven by the driving wheel of the driving wheel set. The at least one holding module is arranged between the two rotating disks and coupled with the at least one driven wheel.
