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 experienced 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, can be used to address some of these circumstances. However, bed pans and urinary catheters have several problems associated therewith. For example, bed pans can be prone to discomfort, pressure ulcers spills, and other hygiene issues. Urinary catheters be can be uncomfortable, painful, and can cause urinary tract infections.
Recently, non-invasive fluid collection devices have been developed for use with immobile and/or limited mobility individuals. By non-invasive, it is meant that the catheter may be placed externally (e.g., outside an opening of the urethra). In some applications, non-invasive fluid collection devices may be designed for solely male or solely female wearers due to differences in external anatomy. However, the external anatomy of some wearers may not conform to typical male or female anatomy. For example, male wearers with excess adipose tissue may have “buried” anatomy that partially or completely obscures the shaft and/or head of the penis. In another example, some male wearers may have micro genitalia or suffer from retracted genitalia (e.g., due to side effects of certain medication). Fluid collection devices designed for typical male genitalia may be less effective or ineffective for these wearers.
Thus, users and manufacturers of fluid collection devices continue to seek new and improved devices and systems to collect bodily fluids that can accommodate a broader range of anatomy.

Features from any of the disclosed embodiments may be used in combination with one another, without limitation. In addition, other features and advantages of the present disclosure will become apparent to those of ordinary skill in the art through consideration of the following detailed description and the accompanying drawings.
The drawings illustrate several embodiments of the present disclosure, wherein identical reference numerals refer to identical or similar elements or features in different views or embodiments shown in the drawings.
Embodiments disclosed herein are directed to fluid collection devices and portions thereof. The fluid collection devices disclosed herein are configured to collect fluids from an individual. The fluids collected by the fluid collection devices can include urine. The fluids collected by the fluid collection devices can also include at least one of vaginal discharge, penile discharge, reproductive fluids, blood, sweat, or other bodily fluids.
The fluid collection devices may include one or more components for drawing (e.g., wicking) fluid from a wearer and/or a surface of the fluid collection device into an interior of the fluid collection device. In some embodiments, the fluid collection devices may include a fluid permeable body for wicking fluid into the fluid collection device. In some embodiments, the fluid permeable body may include a fluid permeable membrane at least partially surrounding a support. In some embodiments, the support may be a fluid permeable support. In some embodiments, the fluid collection device may include a fluid permeable support without a fluid permeable membrane. The support alone or in combination with the fluid permeable membrane may direct fluids to an interior of the fluid collection device where the fluid may be removed from the fluid collection device.
As described herein, the fluid collection devices may be used on both male and female wearers and/or male or female wearers with non-standard anatomy (e.g., buried anatomy, micro anatomy).
In some applications, the fluid collection device 100 may be positioned proximate to a urethra and urine may enter the interior region of the fluid collection device 100 via the opening 106. The fluid collection device 100 is configured to receive the fluids into the chamber 104 via the opening 106. For example, the opening 106 can exhibit an elongated shape that is configured to extend from a first location below the urethral opening (e.g., at or near the anus or perineum) to a second location above the urethral opening (e.g., at or near the pubic bone). The opening 106 can extend longitudinally along the fluid impermeable barrier. The opening 106 in the fluid impermeable barrier 102 can exhibit a width that is measured transverse to the longitudinal direction and may be at least about 10% of the circumference of the fluid collection device 100, such as 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 circumference of the fluid collection device 100. The opening 106 can exhibit a width that is greater than 50% of the circumference of the fluid collection device 100 since a vacuum (e.g., suction) through a conduit 108 pulls the fluid into the conduit 108. In some embodiments, the opening 106 may be vertically oriented (e.g., having a major axis parallel to the longitudinal axis of the device 100). In some embodiments (not shown), the opening 106 may be horizontally oriented (e.g., having a major axis perpendicular to the longitudinal axis of the device 100). In some embodiments, the inward border or edge 129 of the fluid impermeable barrier 102 defines the opening 106. The edge 129 can include two opposing arced portions, the arcs following the outer circumference or periphery of the substantially cylindrical fluid impermeable barrier 102.
The fluid impermeable barrier 102 may also temporarily store the fluids in the chamber 104. As such, the fluid impermeable barrier 102 substantially prevents the fluids from exiting the portions of the chamber 104 that are spaced from the opening 106. The fluid impermeable barrier 102 may be flexible, allowing the fluid collection device 100 to bend or curve when positioned against the body of a wearer. For example, the fluid impermeable barrier 102 can be formed of any suitable fluid impermeable materials, such as a fluid impermeable polymer (e.g., silicone, polypropylene, polyethylene, polyethylene terephthalate, a polycarbonate, etc.), polyurethane films, TPE, oil, another suitable material, or combinations thereof. In some embodiments, the fluid impermeable barrier 102 can include one or more thermoplastic elastomers. The one or more thermoplastic elastomers may be combined with at least one of silicone and oil. In many embodiments, the fluid impermeable barrier 102 can include a composition having at least silicone and oil therein.
The fluid collection device 100 can include a fluid permeable body 120 or layer disposed in the chamber 104. The fluid permeable body 120 can cover or extend across at least a portion (e.g., all) of the opening 106. The fluid permeable body 120 can be configured to wick any fluid away from the opening 106, thereby preventing the fluid from escaping the chamber 104. The fluid permeable body 120 also can wick the fluid generally towards an interior of the chamber 104, as discussed in more detail below. A portion of the fluid permeable body 120 can define a portion of an outer surface of the fluid collection device 100. Specifically, the portion of the fluid permeable body 120 defining the portion of the outer surface of the fluid collection device 100 can be the portion of the fluid permeable body 120 exposed by the opening 106 defined by the fluid impermeable barrier 102. At least a portion of the fluid permeable body 120 exposed by the opening 106 may contact the wearer.
The fluid permeable body 120 can include any material that can wick the fluid. The permeable properties referred to herein can be wicking, capillary action, diffusion, or other similar properties or processes, and are referred to herein as “permeable” and/or “wicking.” Such “wicking” may exclude absorption into the wicking material (e.g., retention of fluid by the material). Put another way, substantially no absorption of fluid in the material may take place after the material is exposed to the fluid and removed from the fluid for a time. While no absorption is desired, the term “substantially no absorption” may allow for nominal amounts of absorption of fluid into the wicking material (e.g., absorbency), such as less than about 10 wt % of the dry weight of the wicking material, less than about 7 wt %, less than about 5 wt %, less than about 3 wt %, less than about 2 wt %, less than about 1 wt %, or less than about 0.5 wt % of the dry weight of the wicking material.
The fluid permeable body 120 can include a one-way fluid movement material. As such, the fluid permeable body 120 can remove fluid from the area around the urethra, thereby leaving the area dry. The fluid permeable body 120 can enable the fluid to flow generally into the chamber 104. For example, the fluid permeable body 120 can include a porous or fibrous material, such as hydrophilic polyolefin or spun nylon fibers. Examples of polyolefin that can be used in the fluid permeable body 120 include, but are not limited to, polyethylene, polypropylene, polyisobutylene, ethylene propylene rubber, ethylene propylene diene monomer, or combinations thereof. The porous or fibrous material can be extruded into a substantially cylindrically shape to fit within the chamber 104 of the fluid impermeable barrier 102. The fluid permeable body 120 can be manufactured according to various manufacturing methods, such as molding, extrusion, or sintering.
In some embodiments, during use, the fluid permeable body 120 extends from the conduit 108 to interface the fluid impermeable barrier 102 and the opening 106. In some embodiments, a majority of the outer surface 109 (shown in
In some embodiments, the fluid permeable body 120 can include a fluid permeable membrane covering or wrapped around at least a portion of a fluid permeable support (not visible) with both the fluid permeable membrane and the fluid permeable support being disposed in the chamber 104. The fluid permeable membrane can cover or extend across at least a portion (e.g., all) of the opening 106. The fluid permeable membrane can be configured to wick any fluid away from the opening 106, thereby preventing the fluid from escaping the chamber 104. Fluids received in the chamber 104 of the fluid collection device 100 from the urethra can be removed through the conduit 108. The fluid permeable membrane may include a fabric such as gauze (e.g., a silk, linen, polymer based materials such as polyester or polypropylene, or cotton gauze), another soft fabric (e.g., jersey knit fabric or the like), or another smooth fabric (e.g., rayon, satin, or the like).
The conduit 108 may be at least partially disposed in the chamber 104. The conduit 108 (e.g., a tube) includes an inlet 110 at a second end region 127 of the fluid impermeable barrier 102 and an outlet 112 at a first end region 125 of the fluid impermeable barrier 102 positioned downstream from the inlet 110. The conduit 108 provides fluid communication between an interior region of the chamber 104 and a fluid storage container (not shown) or a portable vacuum source (not shown). For example, the conduit 108 may directly or indirectly fluidly couple the interior region of the chamber 104 and/or the reservoir 122 with the fluid storage container or the portable vacuum source.
In the illustrated embodiment, the fluid permeable body 120 defines a bore 132 extending through the fluid permeable body 120 from a first body end 121 of the fluid permeable body 120 to a second body end 123 of the fluid permeable body 120 distal to the first body end 121. In other embodiments, the bore 132 extends only partially into the fluid permeable body from the first body end 121 of the fluid permeable body 120.
In some embodiments, the conduit 108 is at least partially disposed in the chamber 104 and interfaces at least a portion of the bore 132 of the fluid permeable body 120. For example, the conduit 108 may extend into the fluid impermeable barrier 102 from the first end region 125 and may extend through the bore 132 to the second end region 127. The conduit 108 may extend beyond the fluid permeable body 120 or flush with the second body end 123. The fluid collected in the fluid collection device 100 may be removed from the interior region of the chamber 104 via the conduit 108. The conduit 108 may include a flexible material such as plastic tubing (e.g., medical tubing). Such plastic tubing may include a thermoplastic elastomer, polyvinyl chloride, ethylene vinyl acetate, polytetrafluoroethylene, etc., tubing. In some embodiments, the conduit 108 may include silicone or latex.
Additional details of the fluid collection device 100 may be found in U.S. application Ser. Nos. 15/171,968, 15/260,103, 15/611,587, 16/369,676, and 16/452,145, which are incorporated herein by reference for any purpose. The fluid collection device 100 shown in
In some embodiments, the adapter 200 may include a flexible fluid impermeable material. The adapter 200 may retain fluids from the penis 201 until the fluid is wicked away by the fluid collection device 100. In some embodiments, the adapter may include polyethylene, polypropylene, and/or polyvinyl chloride. In some embodiments, the adapter 200 may include multiple materials. For example, an external surface 207 may include a fluid impermeable material and the interior surface 203 may include a material that may or may not be fluid impermeable but may be selected based on providing comfort to the wearer's skin (e.g., microfiber fabric).
In some embodiments, the adhesive pad 302 may include one or more tabs 304 extending from a central region 312 of the pad 302. The tabs 304 may facilitate movement by the wearer in some applications. In other embodiments, the tabs 304 may be omitted and the adhesive pad 302 may be substantially rectangular in shape. However, the adhesive pad 302 may define any desired shape (e.g., circular, triangular, elliptical). In some embodiments, the adhesive pad 302 may be sized to cover a majority of a wearer's abdomen (e.g., approximately from the pubic hair line to the sternum). In some embodiments, the adhesive pad 302 may be sized to cover a portion of the wearer's abdomen (e.g., approximately from the pubic hair line to the navel).
The strap 306 may be coupled to the adhesive pad 302 at a first end 303 and further coupled to the fluid collection device 100 at a second end 305. In some embodiments, the second end 305 may include an adhesive to couple the strap 306 to the fluid collection device 100. In some embodiments, the strap 306 may define a hole 308 through which the conduit 108 (shown in
In some embodiments, the adhesive pad 302 may include a flexible material with a low level adhesive on a surface 307 in contact with a user's skin during use. In some embodiments, the flexible material may include a woven and/or nonwoven material. In some embodiments, the flexible material may include a polymer such as PVC, polyethylene and/or polyurethane. In some embodiments, the flexible material may include a natural fiber such as linen and/or cotton. Examples of suitable adhesives may include, but are not limited to, a methacrylate and/or an epoxy diacrylate.
The attachment apparatus 300 may help secure at least one end region (e.g., first end region 125) of the fluid collection device 100 relative to a wearer. In some applications the other end of the fluid collection device 100 (e.g., second end region 127) may be secured, at least in part, by the wearer's legs and/or gluteal cleft. In some embodiments, the attachment apparatus 300 may be used in combination with the adapter 200.
The channel 408 may be sized to accept the conduit 108 and prevent slippage of the conduit 108 by pressure and/or friction. In some embodiments, an inner surface 414 of the channel 408 may be textured and/or include a nonslip coating to prevent movement of the conduit 108 within the channel.
The fastener 404 may be made of a resilient material that may permit temporary deformation. Example materials include polymers (e.g., nylon, polyacetal) and metals (e.g., steel, aluminum). In some embodiments, the opening 410 may be sized to be smaller than a diameter of the conduit 108 in resting state. However, the opening 410 may be temporarily widened by pressing the conduit 108 through the opening 410 and/or applying pressure to one or both tabs 412 as indicated by arrows 415. The conduit 108 may be inserted through the opening 410 into the channel 408 while the opening 410 is in its widened state. Once the conduit 108 is in the channel 408 and/or pressure on the tabs 412 is removed, the opening 410 may return to its resting state, thus securing the conduit 108 in the fastener 404.
Although the fastener 404 is shown as including a clip in
In some embodiments, a length of the strap 416 may be adjustable. For example, the strap 416 may loop around the belt 402 and the attachment apparatus 400 may include a fastener such as a buckle (not shown) for securing the strap 416 at a desired length, similar to fastener 310 of attachment apparatus 300. In another example, the strap 416 may be cut to a desired length and/or include regularly spaced perforations for tearing off a portion of the strap 416 to achieve a desired length. In other embodiments, the length of the strap 416 may not be adjustable, but the “effective length” of the strap 416 may be changed based on where the first end 418 of the strap 416 is coupled to the fluid collection device 100. The adjustability of the strap 416 may permit the fluid collection device 100 to be secured in a variety of positions relative to the belt 402 and/or wearer.
For example, the fluid collection device 100 may be secured in a first position by the fastener 404 and strap 416. As shown in
Alternatively or additionally, the fluid collection device 100 may be secured in a variety of positions based on where along a length of the conduit 108, the fastener 404 is coupled to the conduit 108. Returning to
The attachment apparatus 400 may help secure both ends and/or an entirety of the fluid collection device relative to a wearer. In some embodiments, the attachment apparatus 400 may be used in combination with the adapter 200.

An end cap 542 may be inserted into the aperture 524 to couple a conduit 508 to the fluid collection device 500. The conduit 508 may remove fluids from the chamber 504 via the aperture 524. In some embodiments, the conduit 508 may be substantially the same as conduit 108 of fluid collection device 100.
In some applications, when the fluid collection device 500 is in the configuration shown in
The fluid impermeable barrier 602 may at least partially define an opening 606 into a chamber (not shown), similar to fluid impermeable barrier 102, albeit a different shape. Similar to fluid impermeable layer 502, a bottom surface of the chamber may define a substantially planar surface, rather than a curved or cylindrical surface as chamber 104 of fluid collection device 100. The fluid impermeable barrier 602 may further define an aperture 624 at a first end region 625 of the fluid collection device 600. In some embodiments, the fluid impermeable barrier 602 may include one or more materials that may be included in fluid impermeable barrier of fluid collection device 100.

In some embodiments, the fluid permeable body 620 may include one or more materials that may be included in fluid permeable body 120 of fluid collection device 100.
In some embodiments, such as the one shown, the fluid impermeable barrier 602 may extend on either side of the fluid permeable body 620 to form wings 632. In some embodiments, the fluid impermeable barrier 602 may include an adhesive on a bottom surface (not shown) opposite a surface adjacent to the fluid permeable body 620. In some applications, the adhesive may be used to secure the fluid collection device 600 to an undergarment of a wearer. In some embodiments, the wings 632 may further secure the fluid collection device 600 to the undergarment. For example, the wings 632 may adhere to the inner surface of leg portions of the undergarment. In another example, the fluid collection device 600 may be secured to an upper surface of a crotch portion of the undergarment and the wings 632 may be folded and secured to a lower surface of the crotch portion.
In some embodiments, the hood 630 may include a flexible fluid impermeable material. The hood 630 may retain fluids from the penis 601 until the fluid is wicked away by the fluid permeable body 620. In some embodiments, the hood 630 may include polyethylene, polypropylene, and/or polyvinyl chloride. In some embodiments, the hood 630 may include multiple materials. For example, an external surface 618 may include a fluid impermeable material and the inner surface of the interior 616 may include a material that may or may not be fluid impermeable but may be selected based on providing comfort to the wearer's skin (e.g., microfiber fabric).
In some embodiments, an edge 622 of the hood 630 may be coupled to the fluid impermeable barrier 602. In some embodiments, the edge 622 may be coupled to the fluid permeable body 620. The edge 622 may be coupled to the fluid impermeable barrier 602 and/or fluid permeable body 620 by stitching, ultrasonic welding, an adhesive, and/or other suitable coupling technique.

In some embodiments, the fluid collection device 700 may further include a liner 936 at a perimeter of the opening 906. The liner 936 may allow for air flow and/or prevent leaks. The liner 936 may further provide a comfortable fit and/or feeling against the skin of the wearer. The liner 936 may include an open cell foam in some embodiments. In some embodiments, the liner 936 may include a hydrophobic material and/or a hydrophobic coating, which may reduce or prevent leaks of fluid from the opening 906. In some embodiments, the liner 936 may include an adhesive on an edge 938 adjacent to the wearer's skin when in use to maintain the position of the fluid collection device 900 on the wearer. In other embodiments, the fluid collection device 900 may be held in place by mesh pants (not shown) or other undergarment worn by the wearer over the fluid collection device 900.
The fluid permeable body 920 may include a fluid permeable support 942 at least partially covered by a fluid permeable membrane 940. In some embodiments, the fluid permeable support 942 may include an open cell foam. In some embodiments, the fluid permeable membrane 940 may include a nonwoven material, such as a polyethylene top sheet, selected to provide comfort (e.g., soft, non-chafing) for a wearer's skin. In some embodiments, the fluid permeable body 920 may include one or more materials included in fluid permeable body 120. In some embodiments, the fluid permeable body 920 may be coupled to the inner surface 903 of the fluid impermeable barrier 802 to retain the fluid permeable body 920. In some embodiments, the fluid permeable body 920 may be retained by a wearer's skin when the fluid collection device 900 is worn.
As shown in
Fluid collection devices described herein may be used in fluid collection systems. The fluid collection systems can include a fluid collection device, a fluid storage container, and a portable vacuum source. Fluid (e.g., urine or other bodily fluids) collected in the fluid collection device may be removed from the fluid collection device via a conduit which protrudes into an interior region of the fluid collection device. For example, a first open end of the conduit may extend into the fluid collection device to a reservoir therein. The second open end of the conduit may extend into the fluid collection device or the portable vacuum source. The suction force may be introduced into the interior region of the fluid collection device via the first open end of the conduit responsive to a suction (e.g., vacuum) force applied at the second end of the conduit. The suction force may be applied to the second open end of the conduit by the portable vacuum source either directly or indirectly.
In some embodiments, the portable vacuum source may be disposed in or on the fluid collection device. In such embodiments, the conduit may extend from the fluid collection device and attach to the portable vacuum source at a first point therein. An additional conduit may attach to the portable vacuum source at a second point thereon and may extend out of the fluid collection device, and may attach to the fluid storage container. Accordingly, a vacuum (e.g., suction) may be drawn through fluid collection device via the fluid storage container. Fluid, such as urine, may be drained from the fluid collection device using the portable vacuum source.
In any of the examples, systems or devices disclosed herein, the system of fluid collection device may include moisture sensors (not shown) disposed inside of the chamber of the fluid collection device. In such examples, the moisture sensor may be operably coupled to a controller or directly to the portable vacuum source, and may provide electrical signals indicating that moisture is or is not detected in one or more portions of the chamber. The moisture sensor(s) may provide an indication that moisture is present, and responsive thereto, the controller or portable vacuum device may direct the initiation of suction to the chamber to remove the fluid therefrom. Suitable moisture sensors may include capacitance sensors, volumetric sensors, potential sensors, resistance sensors, frequency domain reflectometry sensors, time domain reflectometry sensors, or any other suitable moisture sensor. In practice, the moisture sensors may detect moisture in the chamber and may provide a signal to the controller or portable vacuum source to activate the portable suction device.
The fluid collection devices and adapters disclosed herein may permit fluid collection devices to accommodate both male and female wearers. The fluid collection devices and adapters disclosed herein may permit fluid collection devices to accommodate wearers with nonstandard anatomy. In some applications, the fluid collection devices and adapters disclosed herein may reduce the need to purchase different devices for different wearers. In some applications, the fluid collection devices and adapters disclosed herein may provide improved performance for wearers with nonstandard anatomy.
As used herein, the term “about” or “substantially” refers to an allowable variance of the term modified by “about” or “substantially” by ±10% or ±5%. Further, the terms “less than,” “or less,” “greater than,” “more than,” or “or more” include, as an endpoint, the value that is modified by the terms “less than,” “or less,” “greater than,” “more than,” or “or more.”
While various aspects and embodiments have been disclosed herein, other aspects and embodiments are contemplated. The various aspects and embodiment disclosed herein are for purposes of illustration and are not intended to be limiting.
