PROBLEM TO BE SOLVED: To provide a preparation apparatus capable of immediately removing an agitation member and further capable of reducing an amount of bone cement adhered to the agitation member when removing it.SOLUTION: A bone cement preparation apparatus 1 comprises a container 2 storing a material for preparing bone cement, and an agitation member 3 disposed in the container 2 to agitate the material. The container 2 is equipped with a lid 21 (a raking member) for raking the bone cement adhered to the agitation member 3 when extracting the member 3 from the container 2. Besides, the lid 21 is equipped with: an opening 21f having a shape capable of extracting the agitation member 3 only when the agitation member 3 trends to a specific direction； and a guide member 21h inducing the agitation member 3 so as to trend to the specific direction.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】撹拌部材を速やかに取り外すことができるとともに、取り外しの際に撹拌部材に付着した骨セメントの量を低減できるようにした調製装置を提供する。【解決手段】骨セメント調製装置１は、骨セメントを調製するための材料が収容される容器２と、前記容器２内に配置され、前記材料を撹拌する撹拌部材３と、を備え、前記容器２は、前記容器２から前記撹拌部材３が引き抜かれる際に前記撹拌部材３に付着した前記骨セメントを掻き取る蓋部２１（掻取部材）を備え、前記蓋部２１は、前記撹拌部材３が特定の方向を向いている場合のみ前記撹拌部材３を引き抜くことができる形状の開口２１ｆと、前記撹拌部材３を前記特定の方向を向くように誘導するガイド部材２１ｈと、を備える。【選択図】図１
