[0011] Embodiments disclosed herein relate to devices, systems, and methods for using a mattress topper to prevent bed soiling and for organizing equipment related to waste collection. The devices, systems, and methods disclosed herein include a mattress topper (e.g., a pad) having a retaining port thereon. The retaining port includes one or more retainers positioned around the outer boundary of the retaining port. One or more retainers hold an object, such as a tube, against the retaining port. The mattress pad includes one or more fixtures of a size and shape that at least temporarily attach the mattress pad to a mattress or bed.

[0012] Devices, systems, and methods disclosed herein provide control over tubing for excrement and fluid collection devices for bedridden patients. Such control allows the excrement and fluid collection device to be held in a selected position on the mattress pad (and patient), providing comfort to the patient by preventing the patient from lying on the drainage tube of the excrement and fluid collection device, preventing leakage or spillage of bodily fluids from the excrement collection device or tubing due to displacement of the tubing or fluid collection device (e.g., twisting or detachment due to the drainage tube being pulled), preventing soiling of the mattress and / or bedding beneath the mattress pad, and preventing unsanitary conditions for the patient due to spillage or leakage of bodily fluids that were not collected by the excrement and fluid collection device or leaked from a displaced excrement and fluid collection device.

[0013] Figure 1 is an isometric view of a mattress pad 100 for collecting excrement according to one embodiment. The mattress pad 100 includes a pad 110, a retaining port 120 on the pad 110, and one or more attachments 130 positioned on the pad 110. The retaining port 120 can be used to at least temporarily hold one or more objects relative to the pad 110, such as one or more drainage tubes 150 (e.g., conduits), fluid collection devices, excrement collection devices, etc. Thus, the retaining port 120 can help organize and hold tubes and devices used by the patient on the mattress pad 100. The retaining port 120 can also be used to position or hold a fluid-impermeable sheet or sanitary pad (e.g., a chuck) in the central area of ​​the mattress pad 100, for example, where the patient's pelvis may be placed on the mattress pad 100 during use.

[0014] Pad 110 is sized and shaped to cover at least a portion of the mattress. For example, pad 110 is dimensioned to fit over at least a portion of a mattress, such as a hospital bed mattress. Pad 110 may be sized to fit over a twin-size mattress, a full-size mattress, and the like. Pad 110 includes a sheet of fabric having fibers made of one or more of fabric 112, such as cotton, polymer (e.g., polyester), satin, silk, linen, or a combination thereof (e.g., polycotton). Fabric 112 may be on the upper surface 105 of pad 110, such as the side of pad 110 facing the patient.

[0015] Pad 110 may include a stuffing 114 disposed under the sheet of fabric 112. Stuffing 114 may include cotton fibers, wool fibers, spun plastic fibers (e.g., polyester), feathers, polymer foam, and the like. Stuffing 114 may be provided as a filler (e.g., pieces), a solid body (e.g., a sheet), or a panel. Stuffing 114 may be at least 5 mm thick (when in an uncompressed state), such as 5 mm to 10 cm, 5 mm to 3 cm, 3 cm to 6 cm, 6 cm to 10 cm, less than 10 cm, less than 5 cm, or more than 1 cm.

[0016] The pad 110 may include one or more fluid-impermeable sheets 116 or 160. The fluid-impermeable sheets 116 or 160 may include fabric, rubber, or a polymer sheet that is impermeable to fluid, such as a plastic sheet (e.g., polyethylene, polyester, vinyl, etc.). The fluid-impermeable sheets 116 or 160 may extend along at least a portion or all of the lateral dimension of the fabric 112 sheet. The fluid-impermeable sheets 116 or 160 may extend across at least the retaining ports 120. The pad 110 may include a fluid-impermeable sheet 116 positioned under the fabric 112 sheet, for example under the filling 114, on top of the filling 114, or both. The fluid-impermeable sheets 116 or 160 prevent or limit fluid from soiling the mattress placed under the mattress pad 100. For example, urine from a patient on the mattress pad 100 can be collected by a urine collection device to prevent urine leaking from the patient or device from reaching the mattress below the mattress pad 100.

[0017] The pad 110 may include a fluid-impermeable sheet 160 placed on or over the sheet of fabric 112. The fluid-impermeable sheet 160 may be sized to fit within or over the area surrounding the retention port 120. For example, the fluid-impermeable sheet 116 may be sized to fit within the retention port to prevent bodily fluids from seeping under the retention port 120. In some examples, the fluid-impermeable sheet 116 may be exposed within the retention port 120, for example, if the retention port 120 does not contain a sheet of fabric 112 within it (e.g., a gap in the sheet of fabric 112). The fluid-impermeable sheet 160 may have the same extent as one or both of the sheets of fabric 112 or the padding 114. The fluid-impermeable sheet 160 may include a comfort pad 165 or fabric, such as a soft fabric, on its uppermost surface to prevent bedsores. In such cases, the fluid-impermeable sheet and the comfort pad 165 attached thereto may be replaced periodically, after use, or after soiling.

[0018] In some examples, one or both of the fabric sheet 112, the stuffing 114, or the fluid-impermeable sheet may be omitted. In such examples, the retention port 120 is disposed on the uppermost layer of the pad 110.

[0019] The retention port 120 is located in the central region of the pad 110 or another suitable region that may be offset from the center of the pad 110. For example, the retention port 120 may be in the middle portion (e.g., the central region) of the mattress pad 100 and disposed in the middle portion that is expected (e.g., appropriate and intended) to hold the patient's pelvic region thereon during use. The retention port 120 includes one or more retainers 122 disposed thereon, for example, around its outer boundary (and at least partially defining the outer boundary).

[0020] One or more retainers 122 hold one or more objects relative to the retention port 120. For example, one or more retainers 122 may include one or more boundary strips. The boundary strip may include a fabric body having one or more fasteners thereon. The strip may include at least a first strip 124 and a second strip 126 disposed at or around the boundary of the retention port 120. The shape of the second strip 126 may at least partially correspond to the shape of the first strip 124 and, for example, may have at least partially the same spread when attached to each other. The first strip(s) 124 may be disposed on the pad 110 and the second strip(s) 126 may move freely. During use, the second strip 126 is applied to the first strip 124 where the fasteners thereon engage to attach at least a portion of the second strip 126 to the first strip 124 at least temporarily. In some examples, the first strip 124 may be at least partially formed from the pad 110, for example, from a portion of the fabric sheet 112. In such examples, the fastener(s) (e.g., hook or loop) may be applied directly on the fabric sheet to at least partially define the retention port 120. Thus, the fasteners (and the strips carrying them) are selectively detachable from each other.

[0021] The second strip 126 may include an uppermost surface (e.g., the surface facing the patient) having a soft and / or smooth material thereon. For example, the uppermost surface of the second strip 126 may include the same fabric as the fabric sheet 112, rubber, polymer, or other fabric, providing a soft and / or smooth contact surface with the patient. Thus, pressure sores or discomfort can be relieved while the medical tube remains secured in the retaining port 120.

[0022] One or more of the pads 110 or the retaining ports 120 include one or more openings, the openings being sized and shaped to accommodate a drainage tube 150. For example, a drainage tube 150 for one or more medical devices may be routed through the retaining ports 120 and / or the pads 110. In such an example, the drainage tube 150 may be fixed to the retaining port 120 and routed through one or more openings so that a portion of the drainage tube 150 is positioned under the pads 110, allowing for, for example, concealing or preventing entanglement of the drainage tube. The drainage tube 150 may be attached to a medical device, such as a urine collection device or an excrement (e.g., feces) collection device.

[0023] The drainage tube 150 may include a medical tube. For example, the drainage tube 150 may consist of one or more polymers, such as silicone, latex, ethylene vinyl acetate (EVA), polytetrafluoroethylene (PTFE), silicone polyurethane, polyamide, polyurethane, polyethylene, other thermoplastics and their block copolymers, or other polymers suitable for medical applications.

[0024] The fasteners are positioned on the first and second strips 124, 126, and the second strip(s) 126 may be attached to the first strip(s) 124. The first strip 124 may include a first fastener, and the second strip 126 may include a second fastener corresponding to the first fastener. The first and second fasteners may include hook-and-loop fasteners, buttons and holes, snaps (e.g., sockets and studs), zippers, magnets, etc. For example, the first strip(s) 124 may include a hook attached to the pad 110, and the second strip(s) 126 may include a loop attached to the fabric body, and the second strip(s) 126 may be free to move to selectively attach to the first strip(s) 124.

[0025] The mattress pad 100 may include one or more fasteners 130. The one or more fasteners 130 are sized and shaped to at least temporarily attach the mattress pad 100 to a mattress (not shown) and may be positioned on the pad 110. The one or more fasteners 130 may be straps, clips, hook-and-loop fasteners, cords, etc., as shown in Figure 1. The straps may be elastic straps, which may be sized and shaped to fit into the corners of the mattress to hold the mattress pad 100 on top of it and to maintain the position of the retaining ports 120 relative to the mattress beneath the mattress pad 100. The one or more fasteners 130 may be spaced apart along the outer edge of the pad 110. For example, the one or more fasteners 130 may include fasteners on one or more corners of the pad 110. In an example (not shown), the pad 110 may be formed as a fitted sheet, and the one or more fasteners 130 may include elastic bodies around the opening of the fitted sheet.

[0026] In some examples, the mattress pad 100 may be sized and shaped to cover only the central area of ​​the mattress, for example, where the patient's pelvic region is expected to be located. In such examples, the retaining port 120 may occupy a larger proportion of the mattress pad 100 than shown in Figure 1. In such examples, the mounting fixture 130 may maintain the position of the mattress pad 100 relative to the mattress below by attaching it, for example, to the rails of the mattress, bedding, or hospital bed. Any of the mattress pads disclosed herein may be the size of the mattress or smaller than the mattress.

[0027] The mattress pad may include tunnels within it, allowing a drainage pipe to fit through them. Figure 2 is an isometric view of a mattress pad 200 for collecting excrement according to one embodiment. The mattress pad 200 includes a pad 110, a retaining port 120 on the pad 110, one or more tunnels 140 within the pad 110, and one or more fixtures 130 positioned on the pad 110. One or more tunnels 140 may be positioned or formed between layers of the pad 110, for example, between a sheet of fabric 112 and one of a fluid-impermeable sheet 116 or a filling 114. One or more tunnels 140 may have a first opening 142 at the edge of the mattress pad 100 and a second opening 144 within or near the retaining port 120. Thus, the drainage pipe 150 may be positioned within the retaining port 120 via the tunnels 140 and not pass over the upper surface 105 of the mattress pad 200.

[0028] The second opening 144 may be located within or adjacent to the retaining port 120. The drain pipe 150 may extend outside the tunnel 140 through the second opening 144 so that the drain pipe 150 is not exposed outside the retaining port 120. In some examples, the second opening 144 may be outside the retaining port 120, and as a result, the drain pipe 150 may extend from the second opening 144 into the retaining port 120 and be held within the retaining port 120 via one or more retainers.

[0029] In some examples, the retaining port may include an openable / closable flap (e.g., a retainer) extending from the side edge of the mattress pad to the central region of the mattress pad. Figure 3 is a schematic diagram of a system 301 for collecting excrement according to one embodiment. The system 301 includes a mattress pad 300, at least one fluid storage container 380, at least one vacuum source 385, and optionally at least one of a fluid collection device 370 or an excrement collection device 390. The mattress pad 300 includes a retaining port 320 with an openable / closable flap 127 for holding and protecting a drainage pipe(s) 150.

[0030] The mattress pad 300 includes a pad 110, a retaining port 320, and one or more attachments 130. The pad 110 includes a sheet of fabric 112, a filling 114, and a fluid-impermeable sheet 116. The retaining port 320 includes one or more of a retainer 122 or an openable flap 127. The flap 127 may be attached to the pad 110, such as a sheet of fabric 112. For example, the flap 127 may be hinged from the pad 110. In some examples, the flap 127 may be attached to the pad 110 at least temporarily from one or more sides of the flap (e.g., one side on a hinge connection, or at least two sides with separate flaps that are not permanently attached to the pad 110). The flap 127 may extend inward from the outer edge of the pad 110 toward the central region of the pad 110 to one or more retainers 122 that at least partially define the retaining port 320. The retaining port 320 includes a fastener 128 positioned on the pad 110 corresponding to a fastener on the openable flap 127, and holds the openable flap 127 in a closed position relative to the pad 110, at least temporarily. For example, the fastener 128 and the corresponding fastener on the openable flap 127 may include any of the fasteners disclosed herein with respect to strips 124 and 126, such as hook-and-loop fasteners, buttons, snaps, etc. The flap 127 may be made of the same or the same material as one or more of the pad 110, such as a sheet of fabric 112, padding 114, and fluid-impermeable sheet 116.

[0031] In some examples, the pad 110 beneath the flap 127 may be thinner than the rest of the pad 110, accommodating the thickness of the flap 127 and resulting in a substantially uniform thickness across the entire pad 110, for example. Such examples may provide a smoother feel and prevent bedsores compared to examples where the flap 127 protrudes above the pad 110.

[0032] During use, the openable and closable flap 127 can be opened to allow the drain pipe 150 to be positioned on the pad 110 below, and then closed to hold the drain pipe 150 in place (for example, by at least temporarily attaching it to the pad 110). The drain pipe 150 is fixed beneath the flap 127 and extends from the outer edge of the mattress pad 300 to its central region (for example, to at least one retainer 122). In some examples, the flap 127 and fasteners 128 may be positioned only adjacent to the central region. In some examples, only one flap 127 and fastener 128 may be used. One or more retainers 122 may be omitted in some examples.

[0033] At least one of the fluid collection device 370 or the waste collection device 390 may be fluidically connected to at least one fluid storage container 380 or vacuum source 385 via a drain pipe 150. For example, at least one of the waste collection device 390 or the fluid collection device 370 may be held in place by a retaining port 320 in the mattress pad 300 and fluidly connected to at least one fluid storage container 380 and / or vacuum source 385 via at least one drain pipe 150. The drain pipe 150 may be positioned below a flap 127 of the retaining port 320 in the mattress pad 300 and at least partially held in place by the flap 127.

[0034] The fluid collection device 370 is sized, shaped, and configured to collect urine or other bodily fluids from a patient's urethra. The fluid collection device 370 can prevent or reduce contamination of clothing, bedding, or the patient with bodily fluids. Figure 4 is an isometric view of the fluid collection device 370 according to one embodiment. Figure 5 is a view along plan AA of the fluid collection device 370 of Figure 4. The fluid collection device 370 includes a fluid-impermeable barrier 402 defining a chamber 404 inside, a porous material 415 at least partially disposed within the chamber 404, and a drain pipe 150 at least partially disposed within the chamber 404.

[0035] The fluid-impermeable barrier 402 at least partially defines the chamber 404 (e.g., the internal region) and the opening 406. For example, the inner surface(s) 403 of the fluid-impermeable barrier 402 at least partially defines the chamber 404 within the fluid collection device 370. The fluid-impermeable barrier 402 at least temporarily retains the fluid(s) within the chamber 404. The fluid-impermeable barrier 402 may be formed from any suitable fluid-impermeable material(s), such as fluid-impermeable polymers (e.g., silicone, polypropylene, polyethylene, polyethylene terephthalate, thermoplastic elastomer(s), polycarbonate, etc.), metal film, natural rubber, another suitable material, or a combination thereof. Thus, the fluid-impermeable barrier 402 substantially prevents the fluid(s) from passing through it.

[0036] In one example, the fluid-impermeable barrier 402 may be air-permeable and liquid-impermeable. In such an example, the fluid-impermeable barrier 402 may be formed of a hydrophobic material that defines a plurality of pores that are air-permeable but liquid-impermeable. In one example, one or more portions of at least the outer surface of the fluid-impermeable barrier 402 may be formed of a soft and / or smooth material to reduce abrasion.

[0037] In some examples, the fluid-impermeable barrier 402 may be tubular (ignoring the opening), for example substantially cylindrical (as shown), rectangular, prismatic, flat, or any other extruded shape (e.g., an I-beam shape, a tube having multiple lobes separated by one or more webs in between). The fluid-impermeable barrier 402 may be sized to fit between the wearer's legs. During use, the outer surface 405 of the fluid-impermeable barrier 402 may be in contact with the wearer, at least partially.

[0038] The opening 406 provides an entry path for fluid into the chamber 404. The opening 406 may be defined by a fluid-impermeable barrier 402, for example, by the inner edge of the fluid-impermeable barrier 402. For example, the opening 406 may be formed within the fluid-impermeable barrier 402 and extend through the fluid-impermeable barrier 402 from the outer surface 405 to the inner surface 403, thereby allowing fluid(s) to enter the chamber 404 from outside the fluid collection device 370. The opening 406 may be positioned and shaped to be adjacent to the wearer's urethra during use of the device. At least a portion of the porous material(s) placed within the chamber 404 may be exposed through the opening 406, allowing fluid to move inward into the chamber 404, for example, through infiltration, suction, or wicking.

[0039] The fluid collection device 370 may be positioned close to the urethra so that urine can enter the chamber 404 through the opening 406. During use, the opening 406 may be elongated and extend from a first position below the urethra to a second position above the urethra (e.g., the vaginal opening or the upper part of the genitals or near thereto). The opening 406 exhibits an elongated shape because the space between the wearer's legs is relatively narrow when the wearer's legs are closed, thereby allowing only the flow of fluid(s) along a path corresponding to the elongated shape of the opening 406 (e.g., an opening extending longitudinally). The opening 406 of the fluid-impermeable barrier 402 may represent a length measured along the longitudinal axis of the fluid collection device 370, which may be at least about 10% of the length of the fluid collection device 370, for example, about 25% to about 50%, about 40% to about 60%, about 50% to about 75%, about 65% to about 85%, or about 75% to about 95% of the length of the fluid collection device 370. The opening 406 of the fluid-impermeable barrier 402 may also represent a width measured across the longitudinal axis of the fluid collection device 370, which may be at least about 10% around the fluid collection device 370, for example, about 25% to about 50%, about 40% to about 60%, about 50% to about 75%, about 65% to about 85%, or about 75% to about 100% of the length of the fluid collection device 370. The opening 406 may have a width exceeding 50% of the circumference of the fluid collection device 370, because the vacuum (e.g., suction) through the conduit 408 draws the fluid through the porous material 415 into the drain pipe 150. The opening 406 may be oriented longitudinally (e.g., having a major axis parallel to the longitudinal axis of the device 370). In some examples (not shown), the opening 406 may be oriented transversely (e.g., having a major axis perpendicular to the longitudinal axis of the device 370).

[0040] The fluid collection device 370 includes a porous material 415 placed within the chamber 404. The porous material 415 may extend over at least a portion (e.g., the entirety) of the opening 406. At least a portion of the porous material 415 may be exposed to the environment outside the chamber 404 through the opening 406. The porous material 415 may be configured to draw up any fluid from the opening 406, thereby preventing the fluid from leaking out of the chamber 404. The permeability properties of the porous material referred to herein may be wicking, capillary action, diffusion, or other similar properties or processes, and are referred to herein as “permeability” and / or “wicking.” Such “wicking” may not involve the absorption of fluid into the porous material. In other words, substantially the absorption of fluid into the porous material is not possible for a period of time after the material has been exposed to the fluid and the fluid has been removed. When non-absorption is desirable, the term "substantially non-absorbent" may allow the nominal amount of fluid absorption into the porous material (e.g., absorbency) to be less than about 10% by weight, less than about 7% by weight, less than about 5% by weight, less than about 3% by weight, less than about 2% by weight, less than about 1% by weight, or less than about 0.5% by weight of the dry weight of the porous material. The porous material 415 may also draw the fluid entirely into the interior of the chamber 404.

[0041] The porous material 415 may include one or more of the fluid permeable membrane 418 or the fluid permeable support 420. The fluid permeable membrane 418 may include any porous material or a material capable of drawing up fluid. For example, the fluid permeable membrane 418 may include a fabric, e.g., gauze (e.g., silk, linen, or cotton gauze), another soft fabric, or another smooth fabric. The fluid permeable membrane 418 may include spun plastic fibers (e.g., nylon), e.g., a spun plastic mat or bed. Forming the fluid permeable membrane 418 from gauze, a soft fabric, and / or a smooth fabric can reduce abrasion caused by the fluid collection device 370.

[0042] The fluid collection device 370 may include a fluid-permeable membrane 418 positioned within the chamber 404. The fluid-permeable membrane 418 may cover at least a portion (e.g., the entirety) of the opening 406. The fluid-permeable membrane 418 may be configured to draw any fluid inward from the opening 406, thereby preventing the fluid from leaking out of the chamber 404.

[0043] The porous material 415 of the fluid collection device 370 may include a fluid-permeable support 420 disposed within the chamber 404. The fluid-permeable support 420 is configured to support a fluid-permeable membrane 418, since the fluid-permeable membrane 418 may be foldable, thin, or formed from other easily deformable materials. For example, the fluid-permeable support 420 may be positioned such that the fluid-permeable membrane 418 is positioned between the fluid-permeable support 420 and the fluid-impermeable barrier 402. Thus, the fluid-permeable support 420 can support and maintain the position of the fluid-permeable membrane 418 on it. The fluid-permeable support 420 may include any material capable of drawing up fluid, for example, any of the fluid-permeable membrane materials disclosed herein. For example, the fluid-permeable support 420 may be formed in a higher density or more rigid form from any fluid-porous material that is less deformable than the fluid-permeable membrane 418, for example, any of the materials disclosed herein for the fluid-permeable membrane 418. In some examples, the fluid-permeable support 420 may include a porous polymer structure (e.g., nylon, polyester, polyurethane, polyethylene, polypropylene, etc.), an open-cell foam, or spun plastic fibers (e.g., nylon fibers). In some examples, the fluid-permeable membrane 418 may include gauze, and the fluid-permeable support 420 may include spun nylon fibers. In some examples, the fluid-permeable support 420 may be formed from fabric, felt, gauze, or a combination thereof. In some examples, the fluid-permeable support 420 may be formed from natural materials, such as cotton, wool, silk, or a combination thereof. In such examples, the material may have a coating, for example, a water-repellent coating, which can prevent or limit the absorption of fluid into the material. In some examples, the fluid-permeable support 420 may be omitted from the fluid collection device 370. In some examples, the fluid-permeable membrane 418 may be optional. For example, the porous material 415 may consist only of the fluid-permeable support 420.

[0044] The fluid-permeable support 420 has greater permeability or fluid-absorbing capacity than the fluid-permeable membrane 418, and can, for example, move fluid from the outer surface to the inner surface of the fluid collection device 370. In some examples, the permeability or wicking capacity of the fluid-permeable support 420 and the fluid-permeable membrane 418 may be substantially the same.

[0045] The fluid-permeable membrane 418 and the fluid-permeable support 420 can at least substantially completely fill the portion of the chamber 404 not occupied by the drain pipe 150. In another example, the fluid-permeable membrane 418 and the fluid-permeable support 420 do not have to substantially completely fill the portion of the chamber 404 not occupied by the drain pipe 150. In such an example, the fluid collection device 370 includes a reservoir 422 within the chamber 404.

[0046] The fluid collection device 370 may include a drain pipe 150 that extends into the chamber 404. As shown in Figure 5, the drain pipe 150 may be located at least partially within the chamber 404. The drain pipe 150 includes an inlet 410 in a first end region and an outlet 412 in a second end region located downstream of the inlet 410. The drain pipe 150 may extend into the chamber 404 to any point. For example, the drain pipe 150 may be inserted into the chamber at the first end region 425 of the fluid collection device 370 and extend through there to the second end region 427 of the fluid collection device 370. The drain pipe 150 may extend within the fluid-impermeable barrier 402 from a first end region 425 (e.g., near the outlet 412) through a second end region 427 (e.g., opposite the first end region 425) to a point near the reservoir 422, so that the inlet 410 is in fluid communication with the reservoir 422. In some examples (not shown), the drain pipe 150 may enter the chamber 404 at the second end region 427, and the inlet 410 of the drain pipe 150 may be located in the second end region 427 (e.g., within the reservoir 422 or coplanar with the fluid-impermeable barrier 402). The fluid collected in the reservoir 422 can be removed from the chamber 404 via the drain pipe 150. In some examples, the inlet 410 may be located at the end of a fluid-permeable support 420 within the second end region 427, for example, coplanar with the end of the fluid-permeable support 420. In some examples, the inlet 410 may be located within the fluid-permeable support 420, for example, between a first end region 425 and a second end region 427.

[0047] The drain pipe 150 may include a flexible material such as a plastic tube (e.g., a medical tube). Such plastic tubes may include thermoplastic elastomers, polyvinyl chloride, ethylene vinyl acetate, polytetrafluoroethylene, and the like. In some examples, the drain pipe 150 may include silicone or latex. In some examples, the drain pipe 150 may include one or more elastic portions, for example, by having one or more diameters or wall thicknesses that allow the conduit to be flexible. In some examples, the drain pipe 150 may be matte or opaque (e.g., black) to obscure the visibility of the fluid(s) inside it.

[0048] The fluid collection device 370 can be operably coupled to the vacuum source 385. For example, the drain pipe 150 fluidly connects the internal region of the chamber 404 to the fluid storage container 380 or the vacuum source 385 (via the fluid storage container 380). Thus, the fluid can be removed from the chamber 404 via the drain pipe 150.

[0049] The fluid-impermeable barrier 402, the fluid-permeable membrane 418, and the fluid-permeable support 420 may be sized and shaped to have a drain pipe 150 that is at least partially located within the chamber 404. For example, at least one of the fluid-permeable membrane 418 and the fluid-permeable support 420 may be configured to form a space for accommodating the drain pipe 150. The fluid-impermeable barrier 402 may define an aperture 424 sized to receive the drain pipe 150. At least one drain pipe 150 may be located within the chamber 404 via the aperture 424. The aperture 424 may be sized and shaped to form at least a substantially liquid-tight seal over the drain pipe 150, thereby substantially preventing the fluid(s) from leaking out of the chamber 404. The fluid collected by the fluid collection device 370 may be removed from the chamber 404 via the drain pipe 150.

[0050] The porous material 415 (e.g., a fluid-permeable membrane 418 and a fluid-permeable support 420) does not have to substantially completely fill the portion of the chamber 404 not occupied by the discharge pipe 150. The fluid collection device 370 may include a reservoir 422 therein. As shown, the reservoir 422 is a substantially empty portion of the chamber 404. The reservoir 422 can be defined between the fluid-impermeable barrier 402 and the porous material 415 (e.g., one or both of the fluid-permeable membrane 418 and the fluid-permeable support 420). The reservoir 422 may be located in a portion of the fluid collection device that is expected (e.g., appropriate and intended) to be located at a gravimetrically low point when the user is wearing the fluid collection device. Although shown in the second end region 427, the reservoir 422 may be located in any portion of the chamber 404, for example, the first end region 425.

[0051] In some examples, the fluid-permeable support 420 is separated from at least a portion of the drain pipe 150, and the reservoir 422 may be defined between the fluid-permeable support 420 and the drain pipe 150.

[0052] As shown in Figure 5, the end of the drain pipe 150 may extend beyond the fluid-permeable membrane 418 and / or fluid-permeable support 420, for example, into the reservoir 422. In some examples, the inlet 410 does not have to extend into the reservoir 422. In such examples, the inlet 410 may be located within the porous material 415 (fluid-permeable membrane 418 and / or fluid-permeable support 420) or at its end. For example, the end of the drain pipe 150 may have the same extent as the fluid-permeable membrane 418 and / or fluid-permeable support 420, or it may be recessed into the fluid-permeable membrane 418 and / or fluid-permeable support 420.

[0053] By positioning the inlet 410 at or near a location where it is predicted to be the lowest gravimetric point in the chamber 404 when the user is wearing it, the drain pipe 150 can receive more fluid(s) than if the inlet 410 were located elsewhere, and the possibility of stagnation (e.g., stagnation of fluid(s) which may cause microbial growth and foul odors) can be reduced. For example, the fluid(s) in the fluid-permeable membrane 418 and fluid-permeable support 420 can flow in any direction due to capillary forces. However, the fluid(s) may prefer to flow in the direction of gravity, especially when at least a portion of the fluid-permeable membrane 418 and / or fluid-permeable support 420 is saturated with fluid(s). Therefore, one or more of the inlet 410 or reservoir 422 can be located in the second end region 427.

[0054] Fluid-impermeable barriers, fluid-permeable membranes, fluid-permeable supports, chambers, conduits, and other embodiments of their shapes and configurations are disclosed in Patent Documents 1 to 3 filed on June 2, 2017, each of which disclosures are incorporated herein by reference in their entirety.

[0055] Returning to Figure 3, the drainage pipe 150 may be fluidly connected to the excrement collection device 390. The excrement collection device 390 may be sized, shaped, and configured to collect excrement from the patient, such as liquid or semi-liquid excrement (e.g., feces). The excrement collection device 390 may prevent or reduce contamination of clothing, bedding, or the patient with excrement.

[0056] Figure 6 is an isometric view of an excrement collection device 390 according to one embodiment. The excrement collection device 390 may include an annular body 610, a fluid-impermeable barrier 620, an optional filter bag 630, and one or more ports 640. The excrement collection device 390 includes an annular body 610, a fluid-impermeable barrier 620 forming an excrement chamber 626 therein, an optional filter bag 630 placed inside the excrement chamber 626, and one or more ports 640 placed on the fluid-impermeable barrier 620. The device 390 is attached to a wearer and configured to collect excrement from the wearer and remove liquid from the excrement. The annular body 610 is attached to the wearer around the wearer's anus or fistula and positions the device 390 for use. Excrement enters the excrement chamber 626 through the opening 614 of the annular body 610, and a filter bag 630 inside the excrement chamber 626 filters out solids from the excrement, allowing fluids to pass through. The liquids move to a gravimetrically lower point in the excrement chamber 626, from which they are removed by vacuum or the like.

[0057] The annular body 610 includes a thin interface layer 612 having an opening 614 inside. The annular body 610 may be a complete ring or a partial ring. For example, the annular body 610 may be a disc-shaped body with a hole inside. In some examples, the annular body 610 may include a flat sheet of material with a hole located at or near the end of the material to form a partial ring. The interface layer 612 is fluid-impermeable. For example, the interface layer may include polymer, silicone, etc. The interface layer 612 may consist of a smooth and / or soft material, such as closed-cell foam, silicone, smooth plastic, etc., or it may include a layer facing the outside of a relatively smooth and / or soft material (e.g., silicone). The interface layer 612 may be deformable in response to bending forces. For example, the annular body 610 may be able to fold, bend, etc. The interface layer 612 may be an annular disc, sheet, plate, or other body having an opening 614 inside its outermost circumference. The interface layer 612 is sized and shaped to fit at least partially within the wearer's gluteal cleft when bent, folded, or otherwise manipulated.

[0058] The interface layer 612 can be deformed to complement the wearer's anatomical structure and, for example, to fit within the gluteal cleft. The annular body 610 (interface layer 612) is flexible in response to pressure applied, for example, by the wearer or a medical professional. The annular body 610 is made of a material that allows it to bend in response to external forces without breaking, and may have thickness.

[0059] The annular body 610 (boundary layer 612) may be foldable in response to pressure applied by the wearer or a medical professional. The annular body 610 may be made of a material that allows the annular body to be folded in response to external force without damage, and may have thickness. For example, a medical professional or wearer may fold and / or bend the annular body 610 in half to insert it between the wearer's buttocks and position it within the gluteal cleft during use. Such a fold forms a tip, having at least a portion of the opening 614 therein. Thus, the annular body 610 may be provided as a substantially flat body, a bent body, or a folded body. By folding or bending the annular body 610, the wearer or user (e.g., a medical professional) may position the opening 614 at least partially non-invasively around the wearer's anus or fistula.

[0060] The opening 614 may be located within the outer periphery of the interface layer 612. As shown, the opening 614 may be located at or near the center of gravity of the interface layer 612. The opening 614 may be located closer to the outer periphery of the interface layer 612 than shown. The opening 614 is sized and shaped to fit around (e.g., on) the patient's anus or fistula without obstructing the fistula or anus. For example, the opening 614 may be circular, elliptical, rectangular, or any other shape. Thus, the annular body 610 is sized and shaped to be positioned over the wearer's anus or fistula, positioning the opening 614 around the anus or fistula. Excrement may be directed through the opening 614 to the excrement collection device 390.

[0061] The interface layer 612 of the annular body 610 includes an adhesive 618 thereon, which can adhere to the skin of a subject, for example, within the gluteal cleft. The adhesive 618 may be integrally formed within or placed on the surface facing the outside of the interface layer 612. Such adhesive 618 can fix the excrement collection device 390 in place, as a result, the opening 614 is maintained around or at least near the wearer's anus or fistula. The adhesive 618 may be placed at one or more points between the opening 614 and the outer circumference of the annular body 610. The adhesive 618 may include medical adhesives or any other adhesive that can be safely used on human skin, such as acrylate adhesives (e.g., methacrylate, epoxy diacrylate, or cyanoacrylate adhesives), silicone adhesives, hydrogels, etc.

[0062] The fluid-impermeable barrier 620 is attached to the annular body 610 and holds the received waste in it at least temporarily, preventing leakage to the external environment. The fluid-impermeable barrier 620 includes an opening at a first (e.g., upper) end and a closed second (e.g., lower) end. The fluid-impermeable barrier 620 is formed from a portion (e.g., a layer) containing a fluid-impermeable material, such as a polymer, metal film, or rubber. For example, the fluid-impermeable barrier 620 may include silicone, polypropylene, polyethylene, polyethylene terephthalate, polystyrene, polyurethane, polycarbonate, polyamide, polyester, polyacrylate, polychloroprene, vinyl, polyvinyl chloride, poly(vinylimidazole), latex, silane (e.g., alkylsilane halogens), perfluorinated polymer, polytetrafluoroethylene (PTFE), polyolefin chlorosulfonic acid, polyethylene oxide, a mixture or copolymer of any of the above, or other fluid-impermeable polymers.

[0063] The fluid-impermeable barrier 620 may have one or more transparent portions. The fluid-impermeable barrier 620 may have one or more translucent or opaque portions. For example, the fluid-impermeable barrier 620 may include a transparent window around the filter bag or in the lower portion of the fluid-impermeable barrier 620 so that the user or wearer can monitor the excrement and liquid inside.

[0064] The fluid-impermeable barrier 620 includes an outer surface 622 and an inner surface 624. The outer surface 622 is relatively smooth or soft and can prevent pain or discomfort to the wearer. The inner surface 624 defines the excrement chamber 626. The excrement chamber 626 receives and holds excrement within it. Liquid from the excrement can move through the excrement chamber 626 from the upper region to the lower region (e.g., a gravimetrically lower point).

[0065] The opening of the fluid-impermeable barrier 620 is fitted to the annular body 610, for example, on the outer circumference of the annular body 610. Thus, the excrement received by the excrement collection device 390 enters the excrement chamber 626 through the opening 614 of the annular body 610 fitted to the fluid-impermeable barrier 620. The opening of the fluid-impermeable barrier 620 can be fitted to the annular body 610 on its outer circumference, at one or more points on the inner circumference of the annular body 610, such as the opening 614, or at any point between the outer circumference and the opening 614.

[0066] The opening of the fluid-impermeable barrier 620 may be attached to the annular body 610 by adhesive, welding, or other means. At least a portion of the fluid-impermeable barrier 620 (e.g., the opening of the fluid-impermeable barrier 620) may be formed integrally with the annular body 610, for example, having a one-piece structure. In such an example, one or more portions of the fluid-impermeable barrier may be open when initially formed and then sealed by attaching a filter bag.

[0067] The fluid-impermeable barrier 620 may be substantially cylindrical or conical in shape. For example, the fluid-impermeable barrier 620 may include an upper portion having larger external dimensions than the lower portion of the fluid-impermeable barrier 620. The fluid-impermeable barrier 620 may be formed as a pouch and have opposing sides joined along its edge. In some examples, the fluid-impermeable barrier 620 may include a sump 628 as part of the fluid-impermeable barrier 620, intended to be located in a gravimetrically lower portion of the excrement collection device 390 during use. The sump 628 may include a portion of the fluid-impermeable barrier 620 having a size and shape that directs the fluid in the chamber to one or more ports 640 located on the fluid-impermeable barrier 620 in the sump 628. For example, the sump 628 may include a portion narrower than the upper portion of the excrement chamber 626. The sump 628 may be a side ditch or pocket within the waste chamber 626, or the conical end of the waste chamber 626.

[0068] The excrement collection device 390 optionally includes a filter bag 630, which is placed within the excrement chamber 626 and positioned to receive excrement through the opening 614 of the annular body 610. The filter bag 630 may have a length shorter than the length of the fluid-impermeable barrier 620. Thus, the bottom of the filter bag 630 does not extend to the bottom of the fluid-impermeable barrier 620. The filter bag 630 may be substantially cylindrical and have a closed bottom substantially opposite the opening of the filter bag 630. In some examples, the filter bag is conical. In some examples, the filter bag is configured as a pouch or has a pouch-like shape. The filter bag filters solid excrement from liquid excrement in the stool, thereby preventing solid excrement from clogging the drain pipe 150 (through which liquid excrement is removed from the stool) attached to the excrement collection device 390.

[0069] The filter bag 630 may include a bag or pouch made of mesh material. The mesh material has a sieve size selected to allow fluid to pass through and hold solids within it. The sieve size (e.g., mesh size) includes meshes of at least about 5 micrometers (μm), and may include, for example, meshes of about 5 μm to about 1,500 μm, about 100 μm to about 1,000 μm, about 250 μm to about 500 μm, about 500 μm to about 1,000 μm, less than about 1,500 μm, less than about 400 μm, or greater than about 100 μm. The filter bag 630 may be seamless. The filter bag 630 includes one or more layers of mesh material, for example, a single layer or a double layer.

[0070] The mesh material may contain polymer or natural fiber. For example, the mesh material may contain polymer fiber, such as nylon, polypropylene, polyethylene, polyethylene terephthalate, polystyrene, polyurethane, polycarbonate, polyamide, polyester, polyacrylate, polychloroprene, vinyl, polyvinyl chloride, poly(vinylimidazole), latex, silane (e.g., alkylsilane halogenates), perfluorinated polymer, polytetrafluoroethylene (PTFE), polyolefin chlorosulfonic acid, polyethylene oxide, or any mixture or copolymer of the above. The mesh may be formed from natural fiber such as cotton (e.g., cheesecloth). The mesh material may be woven or nonwoven. The mesh material may be felt of any of the materials disclosed above.

[0071] The filter bag 630 may be attached to the annular body 610 or the fluid-impermeable barrier 620. For example, the filter bag 630 may be attached to the annular body 610 between the opening 614 and its outer circumference. The filter bag 630 may also be attached to the underside of the annular body 610 at a point between the outer circumference of the annular body 610 and the opening 614. In such an example, the filter bag 630 is separated from the fluid-impermeable barrier 620. By separating the filter bag 630 from the fluid-impermeable barrier 620, a space is formed between the filter bag and the fluid-impermeable barrier, allowing for the separation of liquids from solids in the excrement regardless of the wearer's orientation. The mouth of the filter bag 630 may be coupled to the underside of the annular body 610, resulting in the opening 614 being contained within the filter bag 630. The mouth of the filter bag 630 may be coupled to the annular body 610 to surround the opening 614. In other words, excrement passed through the opening 614 may first be processed within the filter bag 630. The opening of the filter bag 630 can be joined to the underside of the annular body 610 by means of adhesive (e.g., any adhesive), stitching, heat welding, stapling, integral molding, etc.

[0072] The filter bag 630 may be attached to the annular body 610 at least in close proximity to the opening 614. The filter bag 630 may be attached to the annular body 610 at the opening 614. For example, the filter bag 630 may be attached to the annular body at the opening 614 by adhesive, sewing, stapling, or other means.

[0073] The filter bag 630 may be attached to the annular body 610 on its outer circumference. In some examples (not shown), the filter bag 630 may be attached to the upper part of the annular body 610 (for example, the portion facing the outside of the interface layer 612) by extending, for example, from the opening 614 to the outside of the waste chamber 626.

[0074] The filter bag 630 has an opening at its upper end. In some examples, the opening of the filter bag 630 may be at least the same width as the opening of the fluid-impermeable barrier 620. Thus, the opening of the filter bag 630 may be attached to the fluid-impermeable barrier 620, for example, at the opening of the fluid-impermeable barrier 620. The opening of the filter bag 630 may be joined to the fluid-impermeable barrier 620 by adhesive (e.g., any adhesive), stitching, heat welding, stapling, integral molding, etc.

[0075] In some examples, the filter bag 630 may be attached to the fluid-impermeable barrier 620 along its inner surface, for example, at an intermediate point between the opening and the lowest limit of the fluid-impermeable barrier 620 around the inner diameter of the fluid-impermeable barrier. For example, the filter bag 630 may be separated from the annular body and the opening of the fluid-impermeable barrier 620 by only a portion of the inner surface of the fluid-impermeable barrier 620.

[0076] The excrement collection device 390 includes one or more ports 640. One or more ports 640, with passages, fluidly connect the excrement chamber 626 to one or more of the drain pipe 150, a vacuum source, or a fluid storage container. One or more ports 640 are located on the fluid-impermeable barrier 620. One or more ports 640 may be located where liquid is expected to be collected in the excrement chamber 626 or near thereto. For example, one or more ports 640 may be located on the fluid-impermeable barrier 620 at a gravimetrically low point of the fluid-impermeable barrier 620 or near thereto, where it is expected (e.g., appropriate and intended), when the wearer is sitting, lying down, leaning, standing, or in any other posture during use. One or more ports 640 may be located in the sump 628 in the lower part of the fluid-impermeable barrier 620. Any number of ports may be used. For example, at least one port 640 may be located inside the fluid-impermeable barrier 620.

[0077] One or more ports 640 are sized and shaped to connect to a drain pipe 150 (or tube) and remove fluid collected in the waste chamber 626. For example, one or more ports 640 are in fluid communication with the waste chamber 626, and the drain pipe 150 is positioned in fluid communication with the waste chamber 626 and used, for example, to remove fluid from there. One or more ports 640 are sized and shaped to receive the drain pipe 150 therein, and may be, for example, a female connector. The female connector may be sized and shaped so that the drain pipe 150 can be inserted therein. One or more ports 640 are configured to receive the drain pipe 150 thereon, and may be, for example, a male connector (e.g., a nipple or tube connector). When the drain pipe 150 is connected to one or more ports 640, the drain pipe 150 fluidly connects the chamber 626 to one or more of the fluid storage container 380 or vacuum sources via one or more ports 640.

[0078] A fluid (e.g., liquid from excrement) can be removed from the excrement chamber of the excrement collection device 390 via the drain pipe 150. The fluid may move through the drain pipe 150 to the fluid storage container 380 via, for example, vacuum force or gravity. The drain pipes 150 from multiple ports 640 may be coupled to a single piece of drain pipe 150 via a manifold (not shown). The manifold may include male or female connectors for mating with the drain pipe 150.

[0079] A suitable example of an excrement collection device 390 is disclosed in Patent Document 4, the entirety of which is incorporated herein by reference. Further examples of excrement collection devices, which may be used in conjunction with the devices, systems, and methods disclosed herein, are, for example, ostomy bags and vomit bags. Such devices are fluidically coupled to a drainage pipe 150 to remove at least a portion of the collected excrement from the drainage pipe 150.

[0080] Returning to Figure 3, at least one of the excrement collection device or fluid collection device is held to the mattress pad 300 by a holding port and fluidically coupled to at least one fluid storage container 380 via at least one drain pipe 150. System 301 is shown with specific fluid collection device 370 and excrement collection device 390, but such devices are merely examples. System 301 or any mattress pad disclosed herein may be used with commercially available urine or feces collection devices.

[0081] The fluid storage container 380 may include a bag for storing bodily fluids (e.g., a drainage bag), a rigid bottle or cup (e.g., a collection jar), or any other sealed container. The fluid storage container(s) 380 may be fluidly connected to a vacuum source(s) 385, for example, via a portion of a drain pipe 150. The vacuum source(s) 385 may provide a vacuum for drawing fluid into the fluid storage container(s) 380 from one or more of the fluid collection devices 370 or waste collection devices 390 via at least one drain pipe 150. The fluid collected in one or more of the fluid collection devices 370 or waste collection devices 390 is moved into the fluid storage container(s) 380 through the drain pipe 150. By having a separate connection on the fluid storage container(s) 380 to the vacuum source(s) 385, fluid removed from the fluid collection devices 370 or waste collection devices 390 may be prevented from entering the vacuum source(s) 385.

In the example, the vacuum source 385 may be powered by one or more of the following: a power cord (e.g., connected to a power socket), one or more batteries, or a manual power source (e.g., a manual vacuum pump). The vacuum source 385 may include one or more of the following: a switch, a button, a plug, a remote, or any other actuator suitable for operating the vacuum source 385. The vacuum source 385 may be selectively operated by a user (e.g., a medical professional, wearer, or caregiver).

[0083] Any mattress pad or component thereof disclosed herein may be used in System 301. For example, some mattress pads may contain more filling than others.

[0084] Figure 7 is an isometric view of a system 701 for collecting excrement according to one embodiment. Figure 8 is an isometric view of a system 701 for collecting excrement with a partially open cover according to one embodiment. The system 701 includes a mattress pad 300, at least one fluid storage container 380, at least one vacuum source 385, and at least one of a fluid collection device 370 or an excrement collection device 390. The mattress pad 700 includes an openable and closable retaining port 720 that houses, holds, and protects a drainage pipe(s) 150 and at least one of the fluid collection device 370 or the excrement collection device 390 at least partially inside the mattress pad 700. The mattress pad 700 includes one or more recesses 715 formed therein that house the fluid collection device 370, the excrement collection device 390, at least one vacuum source 385 (e.g., a vacuum pump), at least one fluid storage container 380, and the drainage pipe 150 which fluidly connects either of the above.

[0085] The mattress pad 700 includes a pad 710. The pad 710 includes a cover 712 and a filling material body 714 disposed within the cover 712. The pad 710 has a thickness that at least partially accommodates one or more of the following: a fluid collection device 370, a waste collection device 390, at least one vacuum source 385, at least one fluid storage container 380, or a drain pipe 150 that fluidly connects any of the aforementioned.

[0086] The cover 712 may, in one or more embodiments, be similar to or identical to the sheet of fabric 112. For example, the cover 712 may include a fabric having fibers made of one or more of the following: cotton, polymer (e.g., polyester), satin, silk, linen, or a combination thereof (e.g., polycotton). The fabric of the cover 712 may be on the top surface of the pad 710, for example, on the side of the pad 710 facing the patient. The cover 712 may be sized and shaped such that it at least partially covers the filling body 714, for example, to wrap around the filling body 714. The cover 712 includes a resealable fabric container for holding the filling material body. For example, the cover 712 may include a zipper 717 or another selectively closure fastener to close the cover 712 over the filling body 714. The zipper 717 may extend around at least a portion of the side of the mattress pad 700, allowing access to one or more portions of the mattress pad 700 within the cover 712.

[0087] As shown in Figure 7, the mattress pad 700 may be thicker than the mattress pad (e.g., topper) 100, 200, or 300, at least in part due to the thickness of the filling material body 714. The filling material body 714 may be similar or identical to the filling 114 in one or more aspects, such as components or dimensions. For example, the filling material body 714 may include cotton fibers, wool fibers, spun plastic fibers (e.g., polyester), feathers, polymer foam, etc. The filling material body 714 may be provided as a solid, a filler (e.g., small pieces), or a panel. The filling material body 714 may have a thickness of at least 4 cm (in an uncompressed state), for example, 4 cm to 15 cm, 4 cm to 8 cm, 8 cm to 12 cm, 12 cm to 15 cm, less than 15 cm, less than 10 cm, or more than 10 cm. The filling material body 714 may be more compressible near its outermost surface, such as closest to the top surface. Therefore, the filling material body 714 may provide comfort to the patient on it and may prevent or dull the patient from being able to feel the components placed within the pad 710.

[0088] The filling material body 714 includes one or more recesses 715 formed therein, which hold components. At least a portion of one or more recesses 715 may be sized and shaped to hold a fluid collection device 370 or an excrement collection device 390, a fluid storage container 380 (e.g., a urine storage container, a feces storage container, etc.), or a vacuum source 385. For example, one or more recesses 715 may be located in a central area, such as within (e.g., below) a retaining port 720, and may house the fluid collection device 370 and the excrement collection device 390 within the pad 710. One or more recesses 715 may be located in an area of ​​the filling material body 714 that is expected (e.g., appropriate and intended) to be located near the foot end of the mattress (on which the mattress pad 700 is placed) when in use. For example, one or more recesses 715 may be located in the foot end area and may house one or more of the fluid storage containers 380 (e.g., a urine storage container, a feces storage container, etc.) or a vacuum source 385. By positioning the recess 715 in the foot area, the contents within it can be prevented from causing discomfort to the patient when they lie on the mattress pad 700, because the relatively light weight of the feet and legs does not compress the mattress pad 700 as much as the torso. In some examples, one or more recesses 715 for housing one or more of the following can be located anywhere within the pad 710, for example, at the periphery of the mattress pad 700, at the head of the mattress pad 700, etc.

[0089] At least a portion of one or more recesses 715 may be connected via connecting recesses 719 of a size and shape that accommodate a drainage pipe 150 therein. The connecting recesses 719 may be located between any of the recesses 715. In some examples, the connecting recesses 719 may be configured as tunnels in the packing body 714. At least some of the one or more recesses 715 and connecting recesses 719 are accessible by opening the cover 712. For example, the cover 712 may be opened by unzipping it, exposing one or more recesses 715, one or more connecting recesses 719, and their contents. In such examples, the contents of the fluid storage container(s) 380 (e.g., urine and excrement) are concealed and not visible, so as not to cause embarrassment to patients and visitors.

[0090] The filling material body 714 may include two or more parts, for example, an upper body and a lower body as shown in Figure 8. One or more recesses 715 and connecting recesses 719 may be formed in the upper and lower bodies of the filling material. In some examples, one or more recesses 715 and connecting recesses 719 may be formed only in the lower body of the filling material, and the upper body of the filling material may be placed on top of it. When the cover 712 is opened, the upper and lower bodies are separated, and the contents of one or more recesses 715 and connecting recesses 719 can be inspected or replaced. For example, a fluid storage container 380 can be replaced or inspected by opening the cover 712.

[0091] The pad 710 may include a fluid-impermeable sheet 716 inside or on the cover 712. For example, the pad 710 may include the fluid-impermeable sheet 716 between the cover 712 and the filling material body 714, for example, on at least its upper surface (e.g., the surface facing the patient). In some examples, the cover 712 may include a fluid-impermeable sheet 716 positioned at least across the retaining port 720. The fluid-impermeable sheet 716 may be similar to or identical to the fluid-impermeable sheet 116 or 160 in one or more embodiments.

[0092] The retaining port 720 is located on the cover 712, for example, in the central region of the cover 712. In one or more embodiments, the retaining port 720 may be similar to or identical to the retaining port 120 or 320. The retaining port 720 includes one or more retainers 722 arranged around its outer boundary (and at least partially defining the outer boundary). In one or more embodiments, one or more retainers 722 are similar to or identical to one or more retainers 122. For example, one or more retainers 722 may include first and second strips with fasteners as disclosed herein with respect to retainer 122.

[0093] The retaining port 720 may include an openable / closable portion 721. The openable / closable portion 721 may include a part of the cover 712, for example, a part of the cover 712 within the retaining port 720. For example, the fluid-impermeable sheet 716 is removable and provides access to the filling material body 714 therein. The retaining port 720 includes the fluid-impermeable sheet 716 attached to the cover 712 in its intermediate region or a portion thereof (for example, the central region). For example, the openable / closable portion 721 may include the fluid-impermeable sheet 716 for the lower surface and the cover 712 for the upper surface. As shown in Figure 7, the openable / closable portion 721 may be held in place of the filling material body 714 by one or more retainers 722, or by one or more retainers specific to the openable / closable portion 721. As shown in Figure 8, the openable / closable portion 721 may be lifted to expose the filling material body 714 therebelow. The openable portion 721 can be closed by attaching the cover 712 and / or the fluid-impermeable sheet 716 to one or more retainers 722, or one or more retainers specific to the openable portion 721. The cover 712 may include one or more openings, such as retaining ports 720, to allow the drain pipe 150 to pass through during use.

[0094] The components shown in Figures 7 and 8 also represent a waste collection system. This waste collection system can be used to collect fluids and waste from patients in beds, such as hospital beds.
