Abstract
A compression device includes: an adhesion surface configured to be adhered to a biological surface; and an inflatable portion configured to compress the biological surface. The inflatable portion defines an accommodation space capable of accommodating a fluid, and the inflatable portion is capable of being inflated in a thickness direction from a flat deflated form and being changed to an inflated form by supplying the fluid to the accommodation space. The inflatable portion is provided with an inflation restricting portion that is provided at a position sandwiched or surrounded by inflation regions inflatable in the thickness direction in a plan view viewed along the thickness direction, and in which inflation in the thickness direction is restricted by the inflation regions.
Claims15
A compression device, comprising:
- an adhesion surface configured to be adhered to a biological surface;
- an inflatable portion configured to compress the biological surface;
- the inflatable portion defining an accommodation space configured to accommodate a fluid, the inflatable portion being configured to be inflated in a thickness direction from a flat deflated form and to be changed to an inflated form by supplying the fluid to the accommodation space;
- wherein the inflatable portion is provided with an inflation restricting portion, the inflation restricting portion being provided at a position sandwiched or surrounded by inflation regions configured to be inflatable in the thickness direction in a plan view viewed along the thickness direction, and in which inflation in the thickness direction is restricted by the inflation regions;
- wherein the inflatable portion defines the accommodation space between two members facing each other in the thickness direction;
- the inflation restricting portion is formed by joining the two members in the thickness direction;
- the two members are two sheet-shaped members that are stacked;
- and
- the accommodation space is defined by a central portion where the two sheet-shaped members are not joined to each other and that is surrounded by peripheral portions of the two sheet-shaped members that are joined to each other.
A compression device, comprising:
- an adhesion surface configured to be adhered to a biological surface;
- an inflatable portion configured to compress the biological surface;
- the inflatable portion defining an accommodation space configured to accommodate a fluid, the inflatable portion being configured to be inflated from a flat deflated form and to be changed to an inflated form by supplying the fluid to the accommodation space;
- an adhesion body having the adhesion surface;
- a compression member attached to the adhesion body and including the inflatable portion;
- wherein the inflatable portion is provided with an inflation restricting portion, the inflation restricting portion configured to restrict inflation of the inflatable portion;
- wherein the compression member includes an inflatable body including the inflatable portion and a support body fixed to the adhesion body and configured to support the inflatable body, and when the inflatable portion is a first inflatable portion;
- wherein the inflatable body includes the first inflatable portion and a second inflatable portion configured to press the first inflatable portion toward a biological surface by being inflated from the flat deflated form and being changed to the inflated form in a state of being sandwiched between the support body and the first inflatable portion;
- and
- wherein the second inflatable portion is not provided with the inflation restricting portion.
