A compression device to be adhered to a biological surface of a living body to apply compression to a puncture site penetrating the biological surface of the living body, the compression device comprising:
- an adhesive sheet that includes an adhesion surface configured to face towards and be adhered to the biological surface, the adhesion surface being a lower surface of the adhesive sheet, the adhesive sheet also including an upper surface spaced from the lower surface of the adhesive sheet in a thickness direction of the adhesive sheet, the adhesive surface being configured to surround an open central area of the adhesive sheet as seen in a plan view of the compression device, the open central area of the adhesive sheet extending in the thickness direction of the adhesive sheet so that the open central area of the adhesive sheet is open at both the upper and lower surfaces of the adhesive sheet, the adhesive sheet possessing an outer periphery;
- a holding body fixed to the upper surface of the adhesive sheet and spanning across the open central area of the adhesive sheet, the holding body including an outer edge;
- a pressing body mounted on the holding body so that the pressing body is held by the holding body at a position in the open central area of the adhesive sheet, the pressing body being configured to expand in the thickness direction to apply the compression to the puncture site penetrating the biological surface of the living body when the adhesive sheet is adhered to the biological surface;
- the adhesive sheet including a receiving portion constituted by a cut-out portion of the adhesive sheet that is cut-out from the outer periphery of the adhesive sheet toward the open central area of the adhesive sheet, the receiving portion being located radially outwardly of the outer edge of the holding body as seen in the plan view of the compression device and being configured to receive an elongated medical insertion member located in the puncture site penetrating the biological surface of the living body;
- the holding body including an identification portion that is visually identifiable in the plan view and that identifies a location for positioning the compression device relative to the elongated medical insertion member when the compression device is adhered to the biological surface of the living body, the identification portion being located adjacent to and inwardly of the receiving portion as seen in the plan view of the compression device;
- the identification portion including a region marker and a position marker;
- the region marker being constituted by a visually identifiable line that outlines a predetermined region in the plan view so that when the adhesive sheet is adhered to the biological surface, the elongated medical insertion portion of the medical insertion member is located within the predetermined region and is surrounded by the visually identifiable line;
- and
- the position marker being an arc shape line in the plan view, the arc shape line being open along a side facing towards the receiving portion, the arc shape line being located within the predetermined region as seen in plan view and identifying a predetermined reference position within the predetermined region outlined by the region marker.
