23 Jul Looseness compensation device for tissue engineering bioreactor support
Abstract
The utility model relates to a looseness compensation device for a tissue engineering bioreactor support. The looseness compensation device is characterized in that a sensor (2) with tensile/compressive stress and torque measurement function is mounted on a drive rod (1), the lower part of the drive rod (1) is hollow, the upper part of an anchor rod (7) is inserted into the hollow lower part of the drive rod (1) through a coupler (3), the coupler (3) adopts an open structure, an adjusting nut (6) and a gland (5) are mounted at the lower part of the coupler (3) in sequence, the adjusting nut (6) is fixed in the axial position and can rotate around the axis, and the adjusting nut (6) can be rotated to control the initial tensile/compressive stress born by the support, so as to achieve the compensation of the looseness of the support. The utility model can serve the function of measuring tensile/compressive stress and torque, and realizes the direct compensation of the looseness of the support through adjusting tensile stress or compressive stress of each support, thereby meeting the requirement of bidirectional twisting motion. Besides, the utility model has the characteristics of simple and compact structure and convenient use.
