Abstract: A compression testing device includes a receiving unit and a pressing unit movable relative to the receiving unit. The receiving unit includes an outer housing, a sleeve inserted removably into the outer housing, and a liquid supplying mechanism. The liquid supplying mechanism is operable to force a culture medium to flow through the outer housing and the sleeve. A specimen unit is disposed removably within the outer housing. Due to the design of the liquid supplying mechanism, a compression test can be performed on the specimen unit, and cells can be cultured on the specimen unit. In this manner, relationship and change between the specimen unit and the cells can be observed in a real life simulating condition.

Abstract: A culture device includes a deformable cell-culture unit that includes a culture membrane and a surrounding wall extending upwardly from a periphery of the culture membrane, and a deformable engaging unit that is connected to the surrounding wall of the deformable cell-culture unit, that is adapted to engage a stretching device, and that has a hardness larger than that of the cell-culture unit.
