Description

BACKGROUND

An individual may have limited or impaired mobility such that typical urination processes are challenging or impossible. For example, the individual may have surgery or a disability that impairs mobility. In another example, the individual may have restricted travel conditions such as those experience by pilots, drivers, and workers in hazardous areas. Additionally, fluid collection from the individual may be needed for monitoring purposes or clinical testing.

Bed pans and urinary catheters, such as a Foley catheter, may be used to address some of these circumstances. However, bed pans and urinary catheters have several problems associated therewith. For example, bed pans may be prone to discomfort, spills, and other hygiene issues. Urinary catheters be may be uncomfortable, painful, and may cause urinary tract infections. Conventional fluid collection devices also may be limited to use when a patient is confined to a bed in a supine position.

Thus, users and manufacturers of fluid collection devices continue to seek new and improved devices, systems, and methods to collect fluid.

The perforations 136 may be distributed such that the fluid is dispersed uniformly throughout the fluid collection container 120 when the fluid flows through the second portion 118b. In some embodiments, the perforations 136 may be 1/16 the diameter of the tube 118. In other embodiments, the perforations may be greater than 1/16 or less than 1/16 the diameter of the tube 118, such that flow and/or fluid distribution is improved.

The absorbent portion 134 of the fluid collection container 120 may include at least one layer including hydrophobic beads 138, at least one layer including an absorbent material 140, and a mesh layer 142 disposed between the at least one layer including hydrophobic beads and the at least one layer including an absorbent material 140. The absorbent portion 134 may be configured to disperse the fluid similar to a “french drain” or a “drainage field.” The tube 118 may be disposed within the at least one layer including hydrophobic beads 138 to allow fluid to flow out of the perforations 136 without clogging the perforations 136 or the tube 118. The fluid may then seep through the hydrophobic beads 138 and into the absorbent material 140, where the fluid is absorbed. The tube 118 may be disposed in a serpentine arrangement and perforations 136 distributed to disperse the fluid uniformly throughout the absorbent portion 134 to maximize the useable lifetime or capacity of the fluid collection pad 110 before it requires a replacement.

In an embodiment, the at least one layer including hydrophobic beads 138 may be located above the at least one layer including an absorbent material 140 such that gravity helps the fluid flow from the tube 118 into the absorbent material 140. In some embodiments, the second portion of the tube 118b may be disposed and/or integrated within the at least one layer of hydrophobic beads 138. The hydrophobic beads 138 may be constructed of plastic or any suitable non-absorbent material. The hydrophobic beads 138 may be at least one of latex, silica, ceramic, glass, metal, or other suitable hydrophobic material. The hydrophobic beads 138 may be disposable and/or recyclable. In some embodiments, the hydrophobic beads 138 may be configured to surround the tube 118b and aid in fluid travel throughout the absorbent portion 134 such that any absorbent material 140 does not clog the perforations 136 or otherwise impede fluid flow from the tube 118 into the absorbent material 140. In some embodiments, the bead diameter may be at least larger than the diameter of the perforations 136 and larger than any holes and/or perforations in the mesh layer 142.

In some embodiments, the absorbent material 140 may include a gelatinous starch. The absorbent material 140 may include a potato or corn starch. In some embodiments, the absorbent material 140 may include a synthetic absorbent, such as polyester or any other suitable hydrophilic absorbent material. In some embodiments, the absorbent material may include woven or non-woven sheet material, cellulosic pulp, synthetic pulp, pulp fibers, sponge material, or other suitable synthetic or natural materials. In other embodiments, the absorbent material 140 may include a nanomaterial or nanofiber membrane configured to expand and/or form a hydrogel. In some embodiments, the absorbent material 140 may be woven into an absorbent fabric. In some embodiments, the absorbent material 140 may include a biodegradable, a non-biodegradable material, or a combination of a biodegradable and a non-biodegradable material. In some embodiments, the absorbent material 140 may be a powder-like consistency to absorb a fluid. The powder-like absorbent may be converted into a gel-like state as it absorbs fluid. In other embodiments, the absorbent material 140 may include a diaper-like absorbent material that converts the material and fluid into a gel-like state as it is collected and absorbed. The absorbent material 140 may be configured and/or constructed of a material to disperse the fluid uniformly throughout the fluid collection container 120 when the fluid flows through the second portion of the tubing 118b. The absorbent material 140 may be constructed of discrete portions of materials having more or less absorbent qualities as the tubing 118, disposed in a serpentine configuration, disperses the fluid through the perforations 136. In other words, the absorbent material 140 may include layers having differing absorbing properties to improve the capacity of the fluid collection pad 110. In some embodiments, layers of absorbent material 140 may be incorporated to improve fluid absorption or uniform distribution within the absorbent portion 134.

In some embodiments, the mesh layer 142 may be disposed between the at least one layer including the hydrophobic beads 138 and the at least one layer including the absorbent material 140. The second portion of the tube 118b may be disposed within the at least one layer of hydrophobic beads 138 and the mesh layer 142 may separate the absorbent material 140 from the tube 118 and prevent clogging the perforations 136. The mesh 142 material may act as a barrier for the absorbent material 140. The mesh layer 142 may be knitted structure of fibers woven together to create a permeable layer. In some embodiments, the mesh layer 142 may be constructed of polyester, nylon, or any other suitable material. The mesh layer 142 also may provide structure to the absorbent portion 134 and thus may be constructed of a sturdier material such as a rigid or semi-rigid plastic or metal.

The fluid collection pad 110 may include an odor neutralizer 144 configured to at least partially neutralize the odor of the fluid. In some embodiments, baking soda and/or lavender may be included to produce a more pleasant smell and neutralize odor. In some embodiments, the odor neutralizer 144 may be included in the absorbent portion 134. The odor neutralizer 144 may be integrated into the absorbent material 140 and/or the mesh layer 142.

In some embodiments, the second portion of the tube 118b may be disposed within and/or on the absorbent portion 134. In these embodiments, the layer including the hydrophobic beads 138 and/or the mesh layer may be omitted from the absorbent portion 134. The absorbent material 140 may include a material that does not gel and/or clog the perforations 136 of the second portion of the tube 118b. In some embodiments, the absorbent material 140 may wick fluid away from the second portion of the tube 118b.
