23 Jul Biaxial rotating bioreactor
Abstract
The utility model relates to the field of tissue engineering, and discloses a biaxial rotating bioreactor. The biaxial rotating bioreactor disclosed by the utility model comprises a first rotating mechanism and a second rotating mechanism, wherein the first rotating mechanism rotates along a first direction, the second rotating mechanism rotates along a second direction, and the first rotating mechanism is physically connected with the second rotating mechanism. A culture tube is arranged on the first rotating mechanism, and the first rotating mechanism drives the culture tube to rotate along the first direction. The second rotation mechanism drives the first rotating mechanism and the culture tube to rotate along the second direction. The culture tube is driven to rotate along two directions through the two rotating mechanisms, and liquid in the tube moves irregularly and collides with the wall of the tube so as to form an omni-directional shear force, so that the culture liquid can enter the inside of a material along each direction of a tissue block, then an effect of bringing out cell respiration wastes and exchanging nutrients is achieved, and thus the in-vitro regeneration of tissue-engineered products is improved, the success rate of regeneration is increased, and a ‘hollow’ phenomenon in the in-vitro culturing of tissue engineering cytoskeleton compounds is solved.
