## Abstract

An example fluid collection assembly includes a fluid impermeable layer. The fluid impermeable layer includes a proximal end region and a distal end region. The fluid impermeable layer also defines at least a chamber, at least one opening that may be between the proximal and distal end regions, and a fluid outlet that may be at the proximal end region. The fluid collection assembly may also include at least one porous material disposed in the chamber. The fluid collection assembly further includes an extension that is at least one of attachable or extends from the distal end region of the fluid impermeable layer. The extension is configured to be disposed within the gluteal cleft (e.g., between the buttocks) to help secure the fluid collection assembly to an individual using the fluid collection assembly.

## Claims

### Claim 1

A fluid collection assembly, comprising:
a fluid impermeable layer including a proximal end region and a distal end region spaced from the proximal end region; the fluid impermeable layer defining at least a chamber, at least one opening, and a fluid outlet;
at least one porous material disposed in the chamber; and
an extension extending from or near the distal end region, the extension configured to be positioned in a gluteal cleft on an individual, the extension at least one of:
reversibly attachable to the fluid impermeable layer;
inflatable; or
configured to change a distance that the extension extends from the distal end region of the fluid impermeable layer.

### Claim 2 (depends on 1)

The fluid collection assembly of claim 1, wherein the extension is reversibly attachable to the fluid impermeable layer.

### Claim 3 (depends on 2)

The fluid collection assembly of claim 2, wherein the fluid impermeable layer includes a first attachment device and the extension includes a second attachment device, the first attachment device and the second attachment device configured to be reversibly attached together.

### Claim 4 (depends on 3)

The fluid collection assembly of claim 3, wherein one of the first attachment device or the second attachment device includes a protrusion and the other of the first attachment device or the second attachment device includes a recess configured to receive the protrusion.

### Claim 5 (depends on 1)

The fluid collection assembly of claim 1, wherein the extension is inflatable.

### Claim 6 (depends on 5)

The fluid collection assembly of claim 5, wherein the extension includes at least one bladder defining an interior region and at least one valve that allows for at least one inflation fluid to be disposed in or removed from the interior region.

### Claim 7 (depends on 1)

The fluid collection assembly of claim 1, wherein the extension is configured to change a distance that the extension extends from the distal end region of the fluid impermeable layer.

### Claim 8 (depends on 7)

The fluid collection assembly of claim 7, further comprising an attachment device, the extension positioned between the attachment device and a portion of the fluid impermeable layer or within the attachment device, the extension including a surface that abuts an interior surface of the attachment device, the surface of the extension of the interior surface of the attachment device including a plurality of ridges and valleys.

### Claim 9 (depends on 1)

The fluid collection assembly of claim 1, wherein the extension extends a distance from the distal end region of the fluid impermeable layer that is 5 cm to 20 cm.

### Claim 10 (depends on 1)

The fluid collection assembly of claim 1, wherein the extension exhibits a flat shape.

### Claim 11 (depends on 1)

The fluid collection assembly of claim 1, wherein the extension exhibits a cylindrical or rounded shape.

### Claim 12 (depends on 1)

The fluid collection assembly of claim 1, wherein the extension is curved.

### Claim 13 (depends on 1)

The fluid collection assembly of claim 1, wherein the fluid outlet is at the proximal end region.

### Claim 14

A fluid collection system, comprising:
a fluid collection assembly including:
a fluid impermeable layer including a proximal end region and a distal end region spaced from the proximal end region; the fluid impermeable layer defining at least a chamber, at least one opening, and a fluid outlet;
at least one porous material disposed in the chamber; and
an extension extending from or near the distal end region, the extension configured to be positioned in a gluteal cleft on an individual, the extension at least one of:
reversibly attachable to the fluid impermeable layer;
inflatable; or
configured to change a distance that the extension extends from the distal end region of the fluid impermeable layer;
a fluid storage container; and
a vacuum source;
wherein the chamber of the fluid collection assembly is in fluid communication with the fluid storage container and the vacuum source via one or more conduits.

### Claim 15

A method of using a fluid collection assembly, the method comprising:
positioning an opening of a fluid collection assembly adjacent to a urethral opening of an individual, the fluid collection assembly including:
a fluid impermeable layer including a proximal end region and a distal end region spaced from the proximal end region; the fluid impermeable layer defining at least a chamber, at least one opening, and a fluid outlet;
at least one porous material disposed in the chamber; and
positioning an extension of the fluid collection assembly in a gluteal cleft of the individual, the extension extending from or near the distal end region of the fluid impermeable layer, the extension at least one of:
reversibly attachable to the fluid impermeable layer;
inflatable; or
configured to change a distance that the extension extends from the distal end region of the fluid impermeable layer.

### Claim 16 (depends on 15)

The method of claim 15, further comprising, when the individual changes positions, at least one of:
detaching the extension from the fluid impermeable layer;
deflating the extension; or
decreasing a distance that the extension extends from the distal end region of the fluid impermeable layer.

### Claim 17 (depends on 15)

The method of claim 15, further comprising, when the individual changes positions, at least one of:
attaching the extension to the fluid impermeable layer;
inflating the extension; or
increasing a distance that the extension extends from the distal end region of the fluid impermeable layer.

### Claim 18 (depends on 15)

The method of claim 15, further comprising attaching or detaching the extension from the fluid impermeable layer.

### Claim 19 (depends on 15)

The method of claim 15, further comprising inflating or deflating the extension.

### Claim 20 (depends on 15)

The method of claim 15, further comprising changing a distance that the extension extends from the distal end region of the fluid impermeable layer.
