Compression device and compression method

A compression device comprising:

• an adhesion sheet possessing a thickness extending in a thickness direction of the adhesion sheet between a first side of the adhesion sheet and an opposite second side of the adhesion sheet, the adhesion sheet including an adhesion surface on the first side of the adhesion sheet to contact a biological surface and adhere the compression device to the biological surface;
• the adhesion sheet being an annular-shaped adhesion sheet as seen in a plan view, the annular-shaped adhesion sheet having, as seen in the plan view, an inner periphery surrounding a region that is devoid of the adhesion sheet;
• an upstanding support portion fixed to the annular-shaped adhesion sheet on the second side of the annular-shaped adhesion sheet;
• a holder;
• an expandable expander configured to compress the biological surface when the adhesion surface of the annular-shaped adhesion sheet is adhered to the biological surface, the expandable expander being mounted on the holder so that the expandable expander is positioned, as seen in the plan view, in the region that is surrounded by the inner periphery of the annular-shaped adhesion sheet and that is devoid of the adhesion sheet, the expandable expander being configured to protrude further toward the first side of the adhesion sheet in the thickness direction than the adhesion surface of the adhesion sheet;
• and
• an arm portion that removably connects the holder and the expandable expander to the support portion so that the holder and the expandable expander are disassemblable from the support portion.

• an expandable expander mounted on the holder;
• an arm portion configured to removably connect the holder to the upstanding support portion so that:
• i) the expandable expander mounted on the holder is positioned, as seen in the plan view, in the region that is surrounded by the inner periphery of the annular-shaped adhesion sheet and that is devoid of the adhesion sheet;
• and ii) the arm portion when connected to the support portion is separable from the support portion to disassemble the holder and the expandable expander from the support portion;
• and
• the expandable expander being configured to protrude further toward the first side of the adhesion sheet in the thickness direction than the adhesion surface of the adhesion sheet when the holder is connected to the upstanding support portion by the arm portion.
