Abstract

A compression device set includes: a compression device to be adhered to a biological surface; and a cover member attachable to and detachable from the compression device. The compression device includes: an adhesive sheet having an adhesion lower surface to be adhered to the biological surface; and a compression member fixed to an upper surface side of the adhesive sheet and configured to compress the biological surface when the adhesion surface is adhered to the biological surface. The adhesive sheet includes a first portion that is in contact with the compression member and a second portion that is not in contact with the compression member. The cover member is configured to be attached to the compression member in a state in which the cover member is configured to come into contact with an upper surface of at least a part of the second portion of the adhesive sheet.

First claim

What is claimed is:

1. A compression device set comprising:
a compression device that is configured to be adhered to a biological surface and that is configured to compress the biological surface; and
a cover member configured to be attached to and detached from the compression device, the compression device including:
an adhesive sheet possessing a lower surface and possessing an upper surface side, the lower surface of the adhesive sheet being an adhesion surface configured to be adhered to the biological surface;
a compression member that is fixed to the adhesive sheet on the upper surface side of the adhesive sheet and that is configured to compress the biological surface in a state in which the adhesion surface of the adhesive sheet is adhered to the biological surface;
the adhesive sheet including a first portion that is in contact with the compression member and a second portion that is not in contact with the compression member; and
the cover member being configured to be attached to the compression member so that the cover member contacts an upper surface of at least a part of the second portion of the adhesive sheet.

2. The compression device set according to claim 1 , wherein
the compression member of the compression device includes:
an expander that is expandable; and
a holding body configured to hold the expander to be expandable in a sheet thickness direction of the adhesive sheet, and

the cover member being configured to be attached to the holding body.

3. The compression device set according to claim 2 , wherein
the second portion of the adhesive sheet includes a peripheral portion located outside an outer edge of the holding body in a plan view seen in the sheet thickness direction, and
the cover member is configured to be attached to the holding body in a state in which the cover member is configured to come into contact with an upper surface of the entire peripheral portion.

4. The compression device set according to claim 2 , wherein
the cover member is locked to the holding body by a part of the cover member engaging with a side end surface of the holding body, the side end surface being located in a sheet in-plane direction orthogonal to the sheet thickness direction.

5. The compression device set according to claim 4 , wherein
the cover member includes:
a clamping portion configured to clamp opposite portions of the side end surface of the holding body; and
a sheet cover portion that protrudes from the clamping portion in the sheet in-plane direction and that is configured to come into contact with the upper surface of at least a part of the second portion of the adhesive sheet in the state in which the clamping portion clamps the opposite portions of the side end surface of the holding body.

6. The compression device set according to claim 5 , wherein
the cover member includes a pair of gripping portions extending from the clamping portion in the sheet thickness direction, the pair of gripping portions being spaced apart by a facing distance, and
the gripping portions being configured to be gripped and released by a user to change the facing distance between the pair of gripping portions and thereby switch the cover member between a locking position in which the clamping portion clamps the opposite portions of the side end surface of the holding body and a locking release position in which the clamping portion does not clamp the opposite portions of the side end surface of the holding body.

7. The compression device set according to claim 4 , wherein
the cover member includes:
a side-end engaging portion that engages with opposite portions of the side end surface of the holding body; and
a sheet cover portion that protrudes from the side-end engaging portion in the sheet in-plane direction and that is configured to come into contact with the upper surface of at least a part of the second portion of the adhesive sheet in a state in which the side-end engaging portion engages with the opposite portions of the side end surface of the holding body,
one of the side-end engaging portion and the opposite portions of the side end surface of the holding body including a convex portion, and
the other one of the side-end engaging portion and the opposite portions of the side end surface of the holding body including a concave portion or a hole in which is fitted the convex portion.

8. The compression device set according to claim 7 , wherein
the cover member includes a pair of gripping portions each extending in the sheet thickness direction from the side-end engaging portion, the pair of gripping portions being spaced apart by a facing distance, and
the gripping portions being configured to be gripped and released by a user to change the facing distance between the pair of gripping portions and thereby switch the cover member between a locking position at which the convex portion is fitted into the concave portion or the hole and a locking release position at which the convex portion is not fitted into the concave portion or the hole.

9. A compression device set comprising:
a compression member and a cover member;
the compression member comprising an adhesive sheet, a holding member and an inflatable body:
the adhesive sheet possessing an upper surface and also possessing a lower surface that is an adhesion surface configured to adhere the adhesive sheet to a biological surface;
the holding member being fixed to the upper surface of the adhesive sheet so that a portion of the upper surface of the adhesive sheet is in contact with the holding member, the holding member possessing a lower surface that faces toward the biological surface when the adhesive sheet is adhered to the biological surface;
the inflatable body being fixed to the holding member and being positioned in underlying relation to the lower surface of the holding member so that the inflatable body is located between the lower surface of the holding member and the biological surface when the adhesive sheet is adhered to the biological surface, the inflatable body having an interior and an outer surface, the inflatable body being expandable upon introducing a fluid into the interior of the inflatable body to press the outer surface of the inflatable body against a portion of the biological surface and apply a compression force to the portion of the biological surface when the adhesive sheet is adhered to the biological surface;
the cover member being attachable to the compression member, the cover member including a surface configured to contact a part of the compression member when the cover member is attached to the compression member so that a force applied to the cover member is transmitted to the adhesive sheet of the compression member to press the adhesion surface of the adhesive sheet into adhering contact with the biological surface.

10. The compression device set according to claim 9 , wherein the upper surface of the adhesive sheet includes a second portion that is not in contact with the holding member, the second portion of the upper surface of the adhesive sheet being located outwardly of the first portion of the upper surface of the adhesive sheet and at least partially surrounding the first portion of the upper surface of the adhesive sheet.

11. The compression device set according to claim 10 , wherein the cover member includes a cover plate portion, a peripheral wall portion connected to and projecting away from the cover plate portion and a flange plate portion connected to and projecting away from the peripheral wall portion, the cover member being configured so that the flange plate portion overlies the second portion of the upper surface of the adhesive sheet
