23 Jul Dynamic mechanical experimental device and method for tissue engineering scaffold
Abstract
The invention discloses a dynamic mechanical experimental device and a dynamic mechanical experimental method for a tissue engineering scaffold. The device comprises a pressure sensor, a reciprocating motor, a cyclic dynamic stress loading component and an assembling bracket used for placing the reciprocating motor and the cyclic dynamic stress loading component, wherein the pressure sensor comprises a sensing gasket and display equipment; the sensing gasket is arranged between the reciprocating motor and the cyclic dynamic stress loading component, and the sensing gasket and the display equipment are connected with the reciprocating motor; the cyclic dynamic stress loading component comprises a lower bracket used for transmitting driving force upwards, a spring used for transmitting dynamic force, an upper bracket used for transmitting pressure stress downwards, an ejector pin used for transmitting the stress to an experimental material, and a positioning porous cover used for fixing the ejector pin and an experimental porous plate. According to the device and method, a simulation experiment in tissue engineering scaffolds of different sizes under cyclic stress environmental loading under the frequency of 1-150Hz can be met, multi-group experiments can be simultaneously performed, and the experimental efficiency is improved.
