23 Jul Dynamic loading and circular perfusion bioreactor
Abstract
The utility model belongs to the fields of bone tissue engineering and cell biomechanics, and relates to a dynamic loading and circular perfusion bioreactor comprising a main body, a sliding sleeve module and a three-dimensional cultivation chamber module, wherein the main body comprises a base, a lateral support plate and an upper support plate, and the lateral support plate is provided with a concaved chute; the sliding sleeve module comprises a sliding sleeve, piezoelectric ceramics, a lifting adjusting screw rod and a fastening screw rod and can stably slide up and down in the concaved chute, and the piezoelectric ceramics penetrate through the sliding sleeve; the three-dimensional cultivation chamber module comprises a cultivation chamber main body the upper surface of which is provided with a through hole through which the piezoelectric ceramics penetrate into the three-dimensional cultivation chamber, the movable end of the piezoelectric ceramics is connected with a loading rod; and the cultivation chamber main body is also provided with a liquid inlet hole and a liquid outlet hole externally connected with a peristaltic pump. The dynamic loading and circular perfusion bioreactor has the characteristics of simple operation, high practicability, good sterile sealing performance, high output accuracy of loading stress as well as timely and accurate data tracking and recording.
