In some embodiments, the present disclosure provides devices for treating or preventing hemorrhoids and methods of using same. ## Claims ### Claim 1 A device for absorbing sweat proximal to the anus of a subject, the device consisting essentially of: a sheet of material having a substantially uniform thickness throughout, and comprising: a first, generally planar portion comprising at least one crease; a second generally dome-shaped portion that protrudes from the first generally planar portion and is surrounded by the first, generally planar portion; and a body-facing surface including: a texture configured to increase adherence of the device to skin of the subject, and a hydrophobic coating, wherein the second generally dome-shaped portion is sized and shaped to be placed in an intergluteal cleft and proximal to the anus of the subject. ### Claim 2 (depends on 1) The device of claim 1, wherein the sheet of material includes a plurality of layers, and wherein the plurality of layers are secured to each other by a compression seal. ### Claim 3 (depends on 1) The device of claim 1, wherein the hydrophobic coating is disposed on only a portion of the body-facing surface. ### Claim 4 (depends on 1) The device of claim 1, wherein the sheet of material does not include cotton. ### Claim 5 (depends on 1) The device of claim 1, wherein the sheet of material does not include an adhesive for increasing adherence of the device to skin of the subject. ### Claim 6 A device for absorbing sweat proximal to the anus of a subject, the device consisting essentially of: a creased multilayer sheet of material having a substantially uniform thickness throughout, and comprising: a first portion surrounding a second portion that protrudes from the first portion; a first, body-facing layer including a surface including a hydrophobic coating configured to attenuate adherence of the first-body-facing layer to skin proximal to the anus of the subject; and a second layer disposed opposite the first, body-facing layer, wherein the first, body-facing layer does not include an adhesive for increasing adherence of the device to skin of the subject. ### Claim 7 (depends on 6) The device of claim 6, wherein the second layer does not include an adhesive for increasing adherence of the device to skin of the subject. ### Claim 8 (depends on 6) The device of claim 6, wherein the first, body-facing layer includes a texture configured to increase adherence of the device to skin proximal to the anus of the subject. ### Claim 9 (depends on 6) The device of claim 6, wherein the first, body-facing layer and the second layer are joined together by a seal. ### Claim 10 (depends on 9) The device of claim 9, wherein the seal is a compression seal. ### Claim 11 (depends on 10) The device of claim 10, wherein the compression seal does not include a chemical or adhesive. ### Claim 12 (depends on 6) The device of claim 6, wherein the second portion protrudes from the first generally planar portion in an arched dome-like shape. ### Claim 13 A device for absorbing sweat proximal to the anus of a subject, the device consisting essentially of: a first, dome-shaped portion having a first thickness and comprising: a body-facing surface, and a hydrophobic coating disposed on at least a portion of the body-facing surface; a second portion substantially surrounding the first, dome-shaped portion and having a second thickness substantially the same as the first thickness; and at least one crease disposed through at least a portion of at least one of the first thickness and the second thickness, wherein the device is sized and shaped to be placed proximal to the anus of the subject. ### Claim 14 (depends on 13) The device of claim 13, wherein the first, dome-shaped portion and the second portion are formed from a plurality of layers of material. ### Claim 15 (depends on 13) The device of claim 13, wherein the device does not include cotton. ### Claim 16 (depends on 13) The device of claim 13, wherein the first, body-facing layer does not include an adhesive for increasing adherence of the device to skin of the subject.
