[0011]

[0002] Embodiments of the present disclosure relate to fluid collection systems and related methods. Many fluid collection device users have limited mobility and often rely on wheelchairs as their primary means of transportation. Many users also spend a significant portion of their day in a seated or supine position. Therefore, it would be beneficial for users and caregivers to have a discrete and portable fluid collection system that allows users to collect fluids at home or while traveling.

[0012] In many of the embodiments described herein, the fluid collection system is compact and configured to be secured or mounted to a wheelchair. In some embodiments, the fluid collection system can be secured or mounted to a chair, wheelchair, or bed, as well as placed or resting on a surface near the user. The fluid collection systems of the embodiments described herein can be portable and discrete, allowing the user to participate in social activities without alerting others to the user's incontinence. The fluid collection pad of the embodiments can include a cushion that improves comfort and provides privacy while sitting. In some embodiments, the fluid collection pad can include a fluid collection reservoir with an absorbent portion disposed therein. The fluid collection reservoir can be configured to be positioned within a cushion. The fluid collection reservoir, pad, and / or parts of the system can be removable and replaceable. The pad can include an odor neutralizer. Additionally, the fluid collection system can include a cushion cover that retains at least the fluid collection pad and is configured to obscure the pad from a perspective outside the seat or bed. The fluid collection pad may be obscured from view outside the cushion and / or obscures the visibility of fluid held within the fluid collection container.

[0013] FIG. 1 is a block diagram of one embodiment of a fluid collection system 10. The fluid collection system 10 can be incorporated into any of the fluid collection system embodiments described herein. The system 10 includes a fluid collection device 12 (e.g., any of the fluid collection assemblies disclosed herein), a fluid collection container 14, and a pump 16. The fluid collection device 12, fluid collection container 14, and pump 16 can be fluidly coupled to one or more tubing 18 (e.g., medical tubing). For example, the fluid collection device 12 can be operably coupled to one or both of the fluid collection container 14 and the pump 16 via the tubing 18. In certain embodiments, the pump 16 can be secured to a chair, wheelchair, or bed and / or can be directly connected to the tubing 18 between the fluid collection device 12 and the fluid collection container 14. Fluid (e.g., urine or other bodily fluids) collected in the fluid collection device 12 can be removed from the fluid collection device 12 via the tubing 18 coupled to the fluid collection device 12. A suction force (eg, vacuum) responsive to the suction force applied to the tube 18 can be introduced into the chamber of the fluid collection device 12 via the inlet of the tube 18 .

[0014] Suction may be applied directly or indirectly to the tubing 18 by the pump 16. Suction may also be applied indirectly via the fluid collection container 14. For example, the outlet of the tubing 18 may be located within or fluidly coupled to the interior region of the fluid collection container 14, with additional tubing 18 extending from the fluid collection container 14 to the pump 16. In this manner, the pump 16 can apply suction to the fluid collection device 12 via the fluid collection container 14. Suction may also be applied directly by the pump 16. For example, the tubing 18 may be located within the pump 16. In certain embodiments, the pump is a peristaltic pump, such that compression of a portion of the tubing 18 applies suction to the system 10, pumping fluid and moving it within the conduit 18. In certain embodiments, the same tubing 18 or additional tubing 18 may extend from the pump 16 to a point outside the fluid collection device 12, such as to the fluid collection container 14. In such an example, the pump 16 may be positioned between the fluid collection device 12 and the fluid collection container 14 .

[0015] The fluid collection container 14 may be sized and shaped to hold fluid therein. The fluid collection container 14 may be a bag (e.g., a drainage bag) or any other enclosure capable of holding fluid, e.g., bodily fluids, as described in further detail herein.

An additional tube 18 may be attached to the fluid collection container 14 at a second point on the container and extend to and be attached to the pump 16. In this manner, a vacuum (e.g., suction) may be drawn through the fluid collection container 14 and through the fluid collection device 12. Fluid, e.g., urine, may be evacuated from the fluid collection device 12 using the pump 16.

[0016] The pump 16 can include one or more pumps configured to create a vacuum, such as manual and electric vacuum pumps, diaphragm pumps, centrifugal pumps, positive displacement pumps, magnetic drive pumps, and peristaltic pumps. The vacuum or suction provided by the pump 16 can remove fluid from the fluid collection device 12. In certain examples, the pump 16 can be powered by one or more of a power cord (e.g., connected to a power socket), one or more batteries, or even human power (e.g., a hand-operated vacuum pump). In certain examples, the pump 16 can be sized and shaped to fit on, within, or on the fluid collection device 12. For example, the pump 16 can include one or more miniaturized pumps or one or more micropumps. The vacuum source of the present disclosure can also include one or more switches, buttons, plugs, remote controls, or any other suitable device for activating the pump 16.

According to certain embodiments, the perforations 136 can be 1 / 16 times the diameter of the tube 118. According to other embodiments, the perforations may be greater than or less than 1 / 16 the diameter of the tube 118 to improve flow and / or fluid distribution.

[0038] The absorbent portion 134 of the fluid collection container 120 can include at least one layer containing hydrophobic beads 138, at least one layer containing absorbent material 140, and a mesh layer 142 positioned between the at least one layer containing hydrophobic beads and the at least one layer containing absorbent material 140. The absorbent portion 134 can be configured to distribute fluids similar to a "French drain" or "drain field." The tubes 118 can be positioned within the at least one layer containing hydrophobic beads 138 to allow fluid to flow through the perforations 136 without clogging the perforations 136 or the tubes 118. The fluid then passes between the hydrophobic beads 138 and soaks into the absorbent material 140, where it can be absorbed. The serpentine arrangement of the tubes 118 and the interspersed perforations 136 help distribute fluid evenly throughout the absorbent portion 134, maximizing the usable life and capacity of the fluid collection pad 110 before it needs to be replaced.

[0039] In some embodiments, at least one layer containing hydrophobic beads 138 can be located above at least one layer containing absorbent material 140, allowing gravity to assist fluid flow from the tube 118 to the absorbent material 140.

In other embodiments, the absorbent material 140 can include nanomaterials or nanofiber membranes configured to expand and / or form hydrogels. In certain embodiments, the absorbent material 140 can be woven into an absorbent fabric. In certain embodiments, the absorbent material 140 can include biodegradable materials, non-biodegradable materials, or a combination of biodegradable and non-biodegradable materials. In certain embodiments, the absorbent material 140 can be of a powder-like consistency that absorbs fluid. The powder-like absorbent material can convert to a gel-like state as it absorbs fluid. In other embodiments, the absorbent material 140 can include a diaper-like absorbent material that collects and absorbs fluid and converts itself and the fluid to a gel-like state. The absorbent material 140 can also be constructed and / or composed of a material that distributes fluid evenly throughout the fluid collection reservoir 120 as the fluid flows through the second portion of the conduit 118b. The absorbent material 140 can also be constructed of individual sections of material that exhibit more or less absorbent qualities as the fluid is distributed through the perforations 136 by the conduits 118 arranged in a serpentine configuration. In other words, layers of different absorbent properties within the absorbent material 140 can improve the capacity of the fluid collection pad 110. According to certain embodiments, a layer of absorbent material 140 may be incorporated to improve fluid absorption and uniform distribution within the absorbent portion 134 .

[0041] In certain embodiments, a mesh layer 142 can be disposed between the layer containing at least one hydrophobic bead 138 and the layer containing at least one absorbent material 140. The second portion of the tube 118b can be disposed within the layer containing at least one hydrophobic bead 138, and the mesh layer 142 can separate the absorbent material 140 from the tube 118, preventing clogging of the perforations 136. The mesh 142 material can act as a barrier to the absorbent material 140. The mesh layer 142 can be a knitted structure, with fibers woven together to create a water-permeable layer. In certain embodiments, the mesh layer 142 can be constructed of polyester, nylon, or any other suitable material. The mesh layer 142 can provide structure to the absorbent portion 134 and can therefore be constructed of a more robust material, such as a rigid or semi-rigid plastic or metal.

[0042] The fluid collection pad 110 can include an odor neutralizer 144 configured to at least partially neutralize the odor of the fluid. According to certain embodiments, baking soda and / or lavender can be included to provide a more pleasant scent and neutralize odors. According to certain embodiments, the odor neutralizer 144 can be included within the absorbent portion 134. The odor neutralizer 144 can also be integrated into the absorbent material 140 and / or mesh layer 142.

[0043] According to certain embodiments, the second portion of the tube 118b can be disposed within and / or on the surface of the absorbent portion 134. According to these embodiments, the hydrophobic bead 138-containing layer and / or mesh layer can be omitted from the absorbent portion 134. The absorbent material 140 can include a material that does not gel and / or clog the perforations 136 in the second portion of the tube 118b. According to certain embodiments, the absorbent material 140 can wick fluid away from the second portion of the tube 118b.
