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 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. While external catheters improve user comfort, leaks may occur due to size of the user, movement of the external catheter, and/or improper placement of the external catheters.

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

DETAILED DESCRIPTION

Embodiments disclosed herein are securement systems for fluid collection devices, and methods of collecting fluid. Fluid collection devices such as external catheters improve user comfort over conventional internal catheters. Leaks, however, may occur with external catheters due to the size of the user, movement of the external catheter, and/or improper placement of the external catheters. Means and systems for securing the fluid collection device to the user disclosed herein are configured to provide the technical effect that results in positionally proper and convenient securement of a fluid collection device, such as an external catheter, in a desired position over the urethra of the user. This securement of the fluid collection device also provides the technical effect of preventing or inhibiting leaks and/or movement of the fluid collection device during use.

Embodiments of the fluid collection devices disclosed herein are configured to collect fluids from an individual. The fluids collected by the fluid collection devices may include urine. The fluids collected by the fluid collection devices may also include at least one of vaginal discharge, penile discharge, reproductive fluids, blood, sweat, or other bodily fluids. Embodiments of the securement systems and fluid collection devices disclosed herein may be used in fluid collection systems. The fluid collection systems may 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 or chamber therein. The second open end of the conduit may extend into the fluid storage container 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.

Fluid collection devices described herein may be shaped and sized to be positioned adjacent to the opening of a female urethra, positioned over a male penis, or otherwise used for fluid collection from male or females. Although the drawings illustrate embodiments generally used with fluid collection devices on a female, fluid collection devices configured for use with a male or female may be used with fluid collection assemblies described herein. In some embodiments, the fluid collection device may include a fluid impermeable barrier at least partially defining a chamber (e.g., interior region of the fluid collection device) of the fluid collection device. The fluid impermeable barrier also defines an opening extending therethrough from the external environment. The opening may be positioned adjacent to a female urethra or have a male urethra positioned therethrough. The fluid collection device may include a fluid permeable body disposed within the fluid impermeable barrier. The conduit may extend into the fluid collection device at a first end region, through one or more of the fluid impermeable barrier, fluid permeable body to a second end region of the fluid collection device. Exemplary fluid collection devices for use with the systems and methods herein are described in more detail below.

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 the 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 some embodiments, one or more (e.g., all) of the securement systems disclosed herein may include or otherwise be configured to secure or position a fluid collection device on a user. FIGS. 1A-1D show a fluid collection device 100 that may be used with any of the securement systems disclosed herein, according to some embodiments. FIG. 1A is an isometric view of a fluid collection device 100, according to an embodiment. The fluid collection device 100 is an example of a female fluid collection device 100 that is configured to receive fluids from a female. The fluid collection device 100 includes a fluid impermeable barrier 102 having a first end region 125 and a second end region 127. The fluid impermeable barrier 102 at least partially defines a chamber 104 (e.g., interior region, shown in FIG. 1C) and includes an inward border or edge 129 defining an opening 106. The fluid impermeable barrier 102 is substantially cylindrical in shape between the first end region 125 and the second end region 127. In other embodiments, the fluid impermeable barrier 102 may include other shapes, such as one of more substantially planar surfaces, triangular, or other suitable shape. The opening 106 is formed in and extends longitudinally through the fluid impermeable barrier 102, thereby enabling fluids to enter the chamber 104 from outside of the fluid collection device 100. The opening 106 may be configured to be positioned at least proximate (e.g., adjacent to, interfacing, or contacting) the opening of a female urethra or over a buried penis of a male.

With the fluid collection device 100 may positioned at least proximate to the opening of the female urethra or over a buried penis, 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 may 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 the vaginal opening) to a second location above the urethral opening (e.g., at or near the clitoris or the pubic hair). The opening 106 may exhibit an elongated shape since the space between the legs of a female is relatively small when the legs of the female are closed, thereby only permitting the flow of the fluids along a path that corresponds to the elongated shape of the opening 106. For example, the opening may extend longitudinally along the fluid impermeable barrier. The opening 106 in the fluid impermeable barrier 102 may 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 may exhibit a width that is greater than 50% of the circumference of the fluid collection device 100 since the vacuum (e.g., suction) through the 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 may include two opposing arced portions, the arc portions following the outer circumference or periphery of the substantially cylindrical fluid impermeable barrier 102. In an embodiment, the fluid impermeable barrier 102 may be configured to be attached to the individual, such as adhesively attached (e.g., with a hydrogel adhesive) to the individual.

The fluid impermeable barrier 102 may also temporarily store the fluids in the chamber 104. For example, the fluid impermeable barrier 102 may 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, thermoplastic elastomer (TPE), rubber, thermoplastic polyurethane, another suitable material, or combinations thereof. 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 is flexible, thereby enabling the fluid collection device 100 to bend or curve when positioned against the body of a wearer. Example fluid impermeable barriers may include, but are not limited to, a fluid impermeable barrier including at least one of Versaflex CL 2000X TPE, Dynaflex G6713 TPE, or Silpuran 6000/05 A/B silicone.

In an embodiment, the fluid impermeable barrier 102 may be air permeable. In such an embodiment, the fluid impermeable barrier 102 may be formed of a hydrophobic material that defines a plurality of pores. In an embodiment, one or more portions of at least the outer surface of the fluid impermeable barrier 102 may be formed from a soft and/or smooth material, thereby reducing chaffing. The fluid impermeable barrier 102 may include markings thereon, such as one or more markings to aid a user in aligning the device 100 on the wearer. For example, a line on the fluid impermeable barrier 102 (e.g., opposite the opening 106) may allow a healthcare professional to align the opening 106 over the urethra of the wearer. In examples, the markings may include one or more of alignment guide or an orientation indicator, such as a stripe or hashes. Such markings may be positioned to align the device 100 to one or more anatomical features such as a pubic bone, etc.

The fluid collection device 100 may include a fluid permeable body 120 or layer disposed in the chamber 104. The fluid permeable body 120 may cover or extend across at least a portion (e.g., all) of the opening 106. The fluid permeable body 120 may 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 may 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 may 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 may be the portion of the fluid permeable body 120 exposed by the opening 106 defined by the fluid impermeable barrier 102 that contacts the user. Moreover, the portion of the fluid permeable device defining the portion of the outer surface of the fluid collection device 100 may be free from coverage by gauze or other wicking material at the opening.

The fluid permeable body 120 can be configured to wick and/or allow transport of fluid away from the opening 106 towards a reservoir 122 and/or an inlet 110 of the conduit 108. The fluid permeable body 120 may include any material that may wick the fluid. The permeable properties referred to herein may be wicking, capillary action, diffusion, or other similar properties or processes, and are referred to herein as “permeable” and/or “wicking.” Such “wicking” or other physical properties may exclude absorption into the fluid permeable body 120, such as not include absorption of the bodily fluid into the fluid permeable body 120. Put another way, substantially no absorption or solubility of the bodily fluids into the material may take place after the material is exposed to the bodily fluids and removed from the bodily fluids for a time. While no absorption or solubility is desired, the term “substantially no absorption” may allow for nominal amounts of absorption and/or solubility of the bodily fluids into the fluid permeable body 120 (e.g., absorbency), such as less than about 30 wt % of the dry weight of the fluid permeable body 110, less than about 20 wt %, less than about 10 wt %, 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 fluid permeable body 210. In an embodiment, the fluid permeable body 210 may include at least one absorbent or adsorbent material.

The fluid permeable body 120 may include a one-way fluid movement fabric. As such, the fluid permeable body 120 may remove fluid from the area around the female urethra, thereby leaving the urethra dry. The fluid permeable body 120 may enable the fluid to flow generally towards a reservoir 122 (shown in FIG. 1D) in the chamber 104 and/or the inlet 110 of the conduit 108. For example, the fluid permeable body 120 may include a porous or fibrous material, such as hydrophilic polyolefin. In some embodiments, the fluid permeable body 120 consists of or consists essentially of a porous or fibrous material, such as hydrophilic polyolefin. Examples of polyolefin that may 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 may be extruded into a substantially cylindrically shape to fit within the chamber 104 of the fluid impermeable barrier 102. The fluid permeable body 120 may include varying densities or dimensions. Moreover, the fluid permeable body 120 may be manufactured according to various manufacturing methods, such as molding, extrusion, or sintering.

In some embodiments, the fluid permeable body 120 includes a singular and porous body. That is, 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 FIG. 1C) of the fluid permeable body 120 interfaces with an inner surface 103 (shown in FIG. 1C) of the fluid impermeable barrier 106. In some embodiments, at least a portion of the singular porous material of the fluid permeable body 120 extends continuously between the opening 106 and the reservoir 122 to wick any fluid from the opening 106 directly to the reservoir 122. Moreover, as the fluid impermeable barrier 102 is flexible and the fluid permeable body 120 is configured to wick fluid from the body rather than absorb fluid from the body and hold the fluid against the body, the fluid collection device 100, in some embodiments, is free from a seal or cushioning ring on the inward edge 129 defining the opening 106. In these and other embodiments, the fluid permeable body 120 includes an outer surface and a single layer or type of material between the opening 106 and the conduit 108 positioned within the fluid permeable body 120.

In some embodiments, the fluid permeable body 120 may include two or more layers of fluid permeable materials and include no (or an absence of) more than two layers of material between the opening 106 and the conduit 108 positioned within the fluid permeable body 120. For example, the fluid collection device 100 may include a fluid permeable membrane covering or wrapping around at least a portion of a fluid permeable body, with both the fluid permeable membrane and the fluid permeable body being disposed in the chamber 104. The fluid permeable membrane may cover or extend across at least a portion (e.g., all) of the opening 106. The fluid permeable membrane may be configured to wick any fluid away from the opening 106, thereby preventing the fluid from escaping the chamber 104. In some embodiments, at least one of the fluid permeable membrane or the fluid permeable support include nylon configured to wick fluid away from the opening 106. The material of the fluid permeable membrane and the fluid permeable support also may include natural fibers. In such examples, the material may have a coating to prevent or limit absorption of fluid into the material, such as a water repellent coating.

The fluid permeable membrane may also wick the fluid generally towards an interior of the chamber 104. The fluid permeable membrane may include any material that may wick the fluid. For example, the fluid permeable membrane may include fabric, such as a gauze (e.g., a silk, linen, polymer based materials such as polyester, 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). Forming the fluid permeable membrane from gauze, soft fabric, and/or smooth fabric may reduce chaffing caused by the fluid collection device 100. Other embodiments of fluid permeable membranes, fluid permeable supports, chambers, and their shapes and configurations are disclosed in U.S. patent application Ser. No. 15/612,325 filed on Jun. 2, 2017; U.S. patent application Ser. No. 15/260,103 filed on Sep. 8, 2016; U.S. patent application Ser. No. 15/611,587 filed on Jun. 1, 2017; PCT Patent Application No. PCT/US19/29608, filed on Apr. 29, 2019, the disclosure of each of which is incorporated herein, in its entirety, by this reference. In many embodiments, the fluid permeable body 120 includes a fluid permeable support including a porous spun nylon fiber structure and a fluid permeable wicking membrane including gauze at least partially enclosing the spun nylon fiber structure. For example, the fluid permeable body 120 may include a gauze or other wicking fabric positioned to contact the skin of the user through the opening 106. In some embodiments, the gauze or other wicking fabric is wrapped around a body of spun nylon fibers material and/or covering both sides of a substantially planar spun nylon fibers material. In some embodiments, the gauze or other wicking fabric covers the side of substantially planar spun nylon fibers material that is oriented towards the skin of the user.

FIG. 1B is a front view of a fluid collection device 100 in use on a female user 150. In use, the fluid permeable body 120 of the fluid collection device is positioned at least proximate to a urethra of the user 150. The fluid permeable body 120 is disposed within a chamber 104 (shown in FIG. 1D) of the fluid impermeable barrier 102 of the fluid collection device 100 and is exposed to the urethra of the user 150 through the opening 106 in the fluid collection device 100. The fluid collection device 100 may be secured to the user with any of a number of securement systems disclosed herein. Fluids received in the chamber 104 of the fluid collection device 100 from the urethra may be removed through the conduit 108.

FIG. 1D is a cross-sectional view of the fluid collection device 100 taken along line 1-1 of FIG. 1A. The fluid collection device 100 also includes the conduit 108 that is 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 202 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 120. In other embodiments, the bore 202 extends only partially into the fluid permeable body from the first body end 121 of the fluid permeable body 120.

In the illustrated embodiment, the conduit 108 is at least partially disposed in the chamber 104 and interfaces at least a portion of the bore 202 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 (e.g., proximate to the outlet 112) and may extend through the bore 202 to the second end region 127 (e.g., opposite the first end region 125) to a point proximate to the reservoir 122 such that the inlet 110 is in fluid communication with the reservoir 122. For example, in the illustrated embodiment, the inlet 110 extends past the second body end 123 and is positioned in the reservoir 122. However, in other embodiments, the inlet 110 may be positioned flush with or behind the second body end 123 of the fluid permeable body 120 that partially defines the reservoir 122. In some embodiments, the second body end 123 extends to the second end region 127 to substantially fill the chamber 104 and cover the inlet 110. 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.

The fluid impermeable barrier 102 may store fluids in the reservoir 122 therein. The reservoir 122 may be an unoccupied portion of the chamber 104 and is void of other material. In some embodiments, the reservoir 122 is defined at least partially by the fluid permeable body 120 and the fluid impermeable barrier 102. For example, in an embodiment, the reservoir 122 may be located at the portion of the chamber 104 that is closest to the inlet 110 (e.g., the second end region). Accordingly, in the embodiment in FIG. 1D, the reservoir 122 is defined by the second body end 123 of the fluid permeable body 120 and the second end region 127 of the fluid impermeable barrier 122. However, the reservoir 122 may be located at different locations in the chamber 104. For example, the reservoir 122 may be located at the end of the chamber 104 that is closest to the outlet 112. In these and other embodiments, the conduit 108 may extend through the first end region 125 of the fluid impermeable barrier 102 and to the reservoir 122 without extending through the fluid permeable body 120. Accordingly, in these and other embodiments, the fluid permeable body 120 may be free from the bore. In another embodiment, the fluid collection device 100 may include multiple reservoirs, such as a first reservoir that is located at the portion of the chamber of the chamber 104 that is closest to the inlet 110 (e.g., second end region) and a second reservoir that is located at the portion of the of the chamber 104 that is closest to the outlet 112 (e.g., first end region). In another example, the fluid permeable body 120 is spaced from at least a portion of the conduit 108 and the reservoir 122 may be the space between the fluid permeable body 120 and the conduit 108. In some embodiments, the fluid permeable body 120 fills or occupies substantially all of the chamber 104, including filling or occupying substantially all of the reservoir 122 is between the inlet 110 and the second end region 127 of the fluid impermeable barrier 102. Other embodiments of reservoirs, fluid impermeable barriers, fluid permeable membranes, fluid permeable bodies, chambers, and their shapes and configurations are disclosed in U.S. patent application Ser. No. 15/612,325 filed on Jun. 2, 2017; U.S. patent application Ser. No. 15/260,103 filed on Sep. 8, 2016; and U.S. patent application Ser. No. 15/611,587 filed on Jun. 1, 2017, the disclosure of each of which is incorporated herein, in its entirety, by this reference.

The fluid impermeable barrier 102 and the fluid permeable body 120 may be configured to have the conduit 108 at least partially disposed in the chamber 104. For example, the fluid permeable body 120 may be configured to form a space that accommodates the conduit 108, such as the bore 202. In another example, the fluid impermeable barrier 102 may define an aperture 124 sized to receive the conduit 108 (e.g., at least one tube). The at least one conduit 108 may be disposed in the chamber 104 via the aperture 124. The aperture 124 may be configured to form an at least substantially fluid tight seal against the conduit 108 or the at least one tube thereby substantially preventing the fluids from escaping the chamber 104.

In some embodiments, the conduit 108 may extend through the fluid permeable body 120 and at least partially into the reservoir 122, as shown in FIG. 1D. In some embodiments, the conduit 108 may extend through the fluid permeable body 120 and terminate at or before the second body end 123 of the fluid permeable body 120 such that the conduit 108 does not extend into the reservoir 122 (or the reservoir 122 is absent of the conduit 108). For example, an end (e.g., the inlet 110) of the conduit 108 may be generally flush or coplanar with the second body end 123 of the fluid permeable body 120. In other embodiments, the end of the conduit 108 may be recessed from the second body end 123 of the fluid permeable body 120. The end (e.g., the inlet 110) of the conduit 108 also may be selectively moveable between partially extending into the reservoir 122 (shown in FIG. 1D) and recessed from or flush with the second body end 123 of the fluid permeable body.

When secured to the fluid collection device 100, the conduit 108 is configured to provide fluid communication with and at least partially extend between one or more of a fluid storage containers and a portable vacuum source, as described below with FIG. 8. For example, the conduit 108 may be configured to be fluidly coupled to and at least partially extend between one or more of the fluid storage containers and the portable vacuum source. In an embodiment, the conduit 108 is configured to be directly connected to the portable vacuum source. In such an example, the conduit 108 may extend from the fluid impermeable barrier 102 by at least one foot, at least two feet, at least three feet, or at least six feet. In another example, the conduit 108 is configured to be indirectly connected to at least one of the fluid storage container or the portable vacuum source. In some examples, the conduit may be frosted or opaque (e.g., black) to obscure visibility of the fluids therein. In some embodiments, the conduit is secured to a wearer's skin with a catheter securement device, such as a STATLOCK® catheter securement device available from C. R. Bard, Inc., including but not limited to those disclosed in U.S. Pat. Nos. 6,117,163; 6,123,398; and 8,211,063, the disclosures of which are all incorporated herein by reference in their entirety.

The inlet 110 and the outlet 112 are configured to provide fluid communication (e.g., directly or indirectly) between the portable vacuum source (not shown) and the chamber 104 (e.g., the reservoir 122). For example, the inlet 110 and the outlet 112 of the conduit 108 may be configured to directly or indirectly fluidly couple the portable vacuum source to the reservoir 122. In an embodiment, the inlet 110 and/or the outlet 112 may form a male connector. In another example, the inlet 110 and/or the outlet 112 may form a female connector. In an embodiment, the inlet 110 and/or the outlet 112 may include ribs that are configured to facilitate secure couplings. In an embodiment, the inlet 110 and/or the outlet 112 may form a tapered shape. In an embodiment, the inlet 110 and/or the outlet 112 may include a rigid or flexible material.

Locating the inlet 110 at or near a gravimetrically low point of the chamber 104 enables the conduit to receive more of the fluids than if inlet 110 was located elsewhere and reduce the likelihood of pooling (e.g., pooling of the fluids may cause microbe growth and foul odors). For instance, the fluids in the fluid permeable body 120 may flow in any direction due to capillary forces. However, the fluids may exhibit a preference to flow in the direction of gravity, especially when at least a portion of the fluid permeable body 120 is saturated with the fluids.

As the portable vacuum source applies a vacuum/suction in the conduit 108, the fluid(s) in the chamber 104 (e.g., such as in the reservoir 122 positioned at the first end region 125, the second end region 127, or other intermediary positions within the chamber 104) may be drawn into the inlet 110 and out of the fluid collection device 100 via the conduit 108.

In an embodiment, the conduit 108 is configured to be at least insertable into the chamber 104. In such an embodiment, the conduit 108 may include one or more markers 131 (shown in FIG. 1A) on an exterior thereof that are configured to facilitate insertion of the conduit 108 into the chamber 104. For example, the conduit 108 may include one or more markings thereon that are configured to prevent over or under insertion of the conduit 108, such as when the conduit 108 defines an inlet 110 that is configured to be disposed in or adjacent to the reservoir 122. In another embodiment, the conduit 108 may include one or more markings thereon that are configured to facilitate correct rotation of the conduit 108 relative to the chamber 104. In an embodiment, the one or more markings may include a line, a dot, a sticker, or any other suitable marking. In examples, the conduit 108 may extend into the fluid impermeable barrier 102 from the first end region (e.g., proximate to the outlet 112) and may extend to the second end region (e.g., opposite the first end region) to a point proximate to the reservoir 122 such that the inlet 110 is in fluid communication with the reservoir 122. In some embodiments (not shown), the conduit 108 may enter the second end region and the inlet 110 may be disposed in the second end region (e.g., in the reservoir 122). 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) as disclosed herein. In some examples, the conduit 108 may include one or more portions that are resilient, such as having one or more of a diameter or wall thickness that allows the conduit to be flexible.

In an embodiment, one or more components of the fluid collection device 100 may include an antimicrobial material, such as an antibacterial material where the fluid collection device may contact the wearer or the bodily fluid of the wearer. The antimicrobial material may include an antimicrobial coating, such as a nitrofurazone or silver coating. The antimicrobial material may inhibit microbial growth, such as microbial growth due to pooling or stagnation of the fluids. In an embodiment, one or more components of the fluid collection device 100 (e.g., impermeable barrier 102, conduit 108, etc.) may include an odor blocking or absorbing material such as a cyclodextrine containing material or a thermoplastic elastomer (TPE) polymer.

In any of the embodiments disclosed herein, the conduits 108 may include or be operably coupled to a flow meter (not shown) to measure the flow of fluids therein, one or more securement devices (e.g., a StatLock securement device, not shown) or fittings to secure the conduit 108 to one or more components of the systems or devices disclosed herein (e.g., portable vacuum source or fluid storage container), or one or more valves to control the flow of fluids in the systems and devices herein. In an embodiment, at least one of portion of the conduit 108 of the fluid collection devices or systems herein may be formed of an at least partially opaque material which may obscure the fluids that are present therein. For example, a first section of the conduit 108 disclosed herein may be formed of an opaque material or translucent material while a second section of the conduit 108 may be formed of a transparent material or translucent material. In some embodiments, the first section may include transparent or translucent material. Unlike the opaque or nearly opaque material, the translucent material allows a user of the devices and systems herein to visually identify fluids or issues that are inhibiting the flow of fluids within the conduit 108.

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.

FIG. 8 is a block diagram of a system 10 for fluid collection, according to an embodiment. The system 10 includes a fluid collection device 12, a fluid storage container 14, and a portable vacuum source 16. The fluid collection device 12 may include any of the fluid collection devices described herein, such as the fluid collection device 100 or the fluid collection device 600. The fluid collection device 12, the fluid storage container 14, and the portable vacuum source 16 may be fluidly coupled to each other via one or more conduits 17. The conduit 17 may include any of the conduits described herein, such as the conduit 108. The fluid collection device 12 may be operably coupled to one or more of the fluid storage container 14 or the portable vacuum source via the conduit 17. Fluid (e.g., urine or other bodily fluids) collected in the fluid collection device 12 may be removed from the fluid collection device 12 via the conduit 17, which protrudes into an interior region of the fluid collection device 12. For example, a first open end of the conduit 17 may extend into the fluid collection device 12 to a reservoir therein. The second open end of the conduit 17 may extend into the fluid storage container 14 or the portable vacuum source 16. The suction force may be introduced into the interior region of the fluid collection device 12 via the first open end of the conduit 17 responsive to a suction (e.g., vacuum) force applied at the second end of the conduit 17. The suction force may be applied to the second open end of the conduit 17 by the portable vacuum source 16 either directly or indirectly.

The suction force may be applied indirectly via the fluid storage container 14. For example, the second open end of the conduit 17 may be disposed within the fluid storage container 14 and an additional conduit 17 may extend from the fluid storage container 14 to the portable vacuum source 16. Accordingly, the portable vacuum source 16 may apply suction to the fluid collection device 12 via the fluid storage container 14. The suction force may be applied directly via the fluid storage container 14. For example, the second open end of the conduit 17 may be disposed within the portable vacuum source 16. An additional conduit 17 may extend from the portable vacuum source 16 to a point outside of the fluid collection device 12, such as to the fluid storage container 14. In such examples, the portable vacuum source 16 may be disposed between the fluid collection device 12 and the fluid storage container 14.

The fluid collection device 12 may be shaped and sized to be positioned adjacent or proximate to a female urethra. The fluid collection member of the fluid collection device 12 may include a fluid impermeable barrier at least partially defining a chamber (e.g., interior region of the fluid collection device member) of the fluid collection device 12. As described in more detail above, the fluid collection device 12 may include a softer, thinner fluid impermeable barrier than conventional fluid collection devices. The fluid impermeable barrier also defines an opening extending therethrough from the external environment. The opening may be positioned on the fluid collection member to be aligned adjacent or proximate to a female urethra. The fluid collection member of the fluid collection device 12 may include a fluid permeable body disposed within the fluid impermeable barrier. The fluid permeably body may include a fluid permeable membrane and fluid permeable support disposed within the fluid permeable membrane. The conduit 17 may extend into the fluid collection device 12 at a first end region, through one or more of the fluid impermeable barrier, fluid permeable membrane, or the fluid permeable support to a second end region of the fluid collection member of the fluid collection device 12. Example fluid collection devices for use with the systems and methods herein are described in more detail below.

In some embodiments, the fluid storage container 14 may include a bag (e.g., drainage bag), a bottle or cup (e.g., collection jar), or any other enclosed container for storing bodily fluids such as urine. In examples, the conduit 17 may extend from the fluid collection device 12 and attach to the fluid storage container 14 at a first point therein. An additional conduit 17 may attach to the fluid storage container 14 at a second point thereon and may extend and attach to the portable vacuum source 16. For example, the fluid storage container 14 may include a container fluidly coupled to a first conduit section that is also fluidly coupled to the fluid collection member of the fluid collection device 12. The container may be fluidly coupled to a second section of the conduit 17 that is also fluidly coupled to a portable vacuum source. In such examples, the portable vacuum source 16 may provide a vacuum/suction through the container to the fluid collection member to provide suction in the chamber of the fluid collection member. Accordingly, a vacuum (e.g., suction) may be drawn through fluid collection device 12 via the fluid storage container 14. As the fluid is drained from the chamber, the fluid may travel through the first section of conduit to the fluid storage container where it may be retained. Fluid, such as urine, may be drained from the fluid collection device 12 using the portable vacuum source 16.

In some embodiments, the portable vacuum source 16 may be disposed in or on the fluid collection device 12. In such examples, the conduit 17 may extend from the fluid collection device and attach to the portable vacuum source 16 at a first point therein. An additional conduit 17 may attach to the portable vacuum source 16 at a second point thereon and may extend out of the fluid collection device 12, and may attach to the fluid storage container 14. Accordingly, a vacuum (e.g., suction) may be drawn through fluid collection device 12 via the fluid storage container 14.

The portable vacuum source 16 may include one or more of a manual vacuum pump, and electric vacuum pump, a diaphragm pump, a centrifugal pump, a displacement pump, a magnetically driven pump, a peristaltic pump, or any pump configured to produce a vacuum. The portable vacuum source 16 may provide a vacuum or suction to remove fluid from the fluid collection member of the fluid collection device 12. In some embodiments, the portable vacuum source 16 may be powered by one or more of a power cord (e.g., connected to a power socket), one or more batteries, or even manual power (e.g., a hand operated vacuum pump). In examples, the portable vacuum source 16 may be sized and shaped to fit outside of, on, or within the fluid collection device 12. For example, the portable vacuum source 16 may include one or more miniaturized pumps or one or more micro pumps. The portable vacuum sources 16 disclosed herein may include one or more of a switch, a button, a plug, a remote, or any other device suitable to activate the portable vacuum source 16. It should be understood that the portable vacuum sources 16 disclosed herein may provide a portable means of providing a suction or vacuum that allows use of the devices and systems herein outside of hospital or care facility environments where vacuum lines are plumbed into patient rooms or large (e.g., larger or heavier than a patient can readily carry) vacuum sources are located. For example, a portable vacuum source may be small and light enough to be carried by a user (e.g., patient) or aid (e.g., nurse) during transportation of the user.
