Patent ID: 7968335

Claim:
A biomechanical stimulation loading system comprising: a mechanical stimulation loading device; a culture receptacle; and a control computer, wherein the mechanical stimulation loading device and the culture receptacle are disposed in a carbon dioxide incubator, wherein the mechanical stimulation loading device comprises: a plurality of weight loading pistons; a piston raising and lowering stage supporting the plurality of weight loading pistons to allow vertical movement of the plurality of weight loading pistons within a designated range; and a stage lifting and lowering mechanism for vertically moving the piston raising and lowering stage, wherein the control computer is configured to drive the stage lifting and lowering mechanism in a specified cycle to effect the vertical movement of the piston raising and lowering stage, and wherein the plurality of weight loading pistons weigh on a culture in the culture receptacle when the piston raising and lowering stage is lowered, a piston mounting stage is installed on the piston raising and lowering stage to allow each weight loading piston in the plurality of weight loading pistons to be supported by being inserted into a respective hole of a plurality of holes formed in the piston mounting stage, and the piston raising and lowering stage includes an opening to allow free vertical movement of the plurality of weight loading pistons.
