Description

BACKGROUND

[0001] 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.

[0002] 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, spills, and other hygiene issues. Urinary catheters be can be uncomfortable, painful, and can cause urinary tract infections.

[0003] US 4,747,166 discloses a urine aspiration system comprising a pad to receive urine. The pad is connected by tubing coupled to a urine collection vessel and vacuum source that when activated draws urine out of the pad to leave the patient feeling dry and comfortable. The pad is provided with a cushioning ring of foam along its periphery, with a pressure-sensitive adhesive on its surface in contact with the patient.

[0004] US 2016 / 0374848 A1 discloses a urine collection device of generally cylindrical form to be placed between the labia of a female wearer with a longitudinally extending opening overlaying the urethra. A thin pliable strip with one end attached to the device and the other end attached to the wearer's body, is used to stabilize the position of the device on the body.

[0005] WO 00 / 40197 discloses an absorbent article sized and configured to fit predominantly between a user's labia and comprising an opposed pair of lateral extensions of the absorbent structure, each having a body-facing surface and an opposite-facing surface with adhesive on the lateral extension body-facing surface for releasably attaching the article to the user's body.

[0006] US 2004 / 0147894 A1 discloses an interlabial pad with a long convex area flanked by substantially flat areas, the long convex area being for insertion between the labia thereby to reduce leakage of menstrual blood.

[0007] US 5,968,026 discloses an absorbent interlabial device which includes a U-shaped liquid-impervious backsheet which surrounds a folded topsheet of liquid-absorbent material and optionally between the topsheet and the backsheet, sheet material providing a pair of lateral extensions to aid insertion of the device and enhance wearer comfort. The US '026 specification includes a summary of earlier interlabial pad design proposals.

[0008] Users and manufacturers of fluid collection devices continue to seek new and improved devices, systems, and methods to collect urine.SUMMARY

[0014] Embodiments disclosed herein are of fluid collection devices and systems. The fluid collection devices include flanges extending from the fluid collection device where the each said flange is positioned to attach to the skin of a user and align the fluid collection device with one or more anatomical structures of the user (e.g., urethra). Systems, and methods of using fluid collection devices and systems, include a vacuum source to remove urine from the fluid collection device. The portable vacuum source may allow for portable usage of the systems and methods herein such as in non-hospital environments.

[0015] A fluid collection device includes a fluid impermeable barrier that at least partially defines a chamber. The fluid impermeable barrier also defines an opening extending therethrough that is configured to be positioned adjacent to a female urethra. The fluid collection device also includes a tube having a channel extending between an inlet and outlet thereof. The inlet is configured to be coupled to a suction source and the outlet is configured to be fluidly coupled to (e.g., in fluid communication with) a fluid storage (vessel or container). The outlet is positioned downstream from the inlet. The channel also defines at least one aperture therein that fluidly couples an interior of the channel to the rest of the chamber.

[0016] The fluid collection devices disclosed herein are configured to collect fluid(s) from an individual. The fluid(s) collected by the fluid collection devices can include urine. The fluid(s) collected by the fluid collection devices can also include at least one of vagina discharge, blood, sweat, or other bodily fluids.

[0017] The fluid collection devices disclosed herein are configured to be used in fluid collection systems. The fluid collection systems disclosed herein include a gas source. Systems that include a gas source can, in some embodiments, resolve several problems associated with systems that include a vacuum source. For example, a system that includes a vacuum source draws fluid(s) towards the vacuum source and deposits most of the fluid(s) in a fluid storage container before the fluid(s) can reach the vacuum source. However, a small quantity of fluid(s) (e.g., vapor from the fluid) can still reach the vacuum source, which can contaminate and / or damage (e.g., rust) the vacuum source. Additionally, a large quantity of the fluid(s) can reach the vacuum source when the fluid storage container is substantially full. However, a system that includes a gas source moves the fluid(s) away from the gas source, thereby preventing contamination and / or damage. For example, a gas source may be used to create a vacuum by flowing a gas past a connected end of the conduit at a perpendicular or oblique angle to the conduit to create a vacuum in the conduit. The fluids are pulled up the conduit and into the gas flow in the direction of the gas flow, which is away from the gas source. In another embodiment, systems that include a vacuum source cannot be used in environments that do not include an available vacuum source (e.g., the environment does not include a vacuum source or the vacuum source is being used). As such, systems that include a gas source can be used in environments that do not include an available vacuum source. A liquid source can be used to create and implement a vacuum in the same way as the gas source. The vacuum source or gas source can be utilized with any of the devices or systems disclosed herein to remove a fluid therefrom.

[0018] FIG. 1 is a block diagram of a system 10 for fluid collection. The system 10 includes a fluid collection device 12, a fluid storage container 14, and a vacuum source 16. The fluid collection device 12, the fluid storage container 14, and the vacuum source 16 may be in fluid communication with (e.g., fluidly coupled to) each other via one or more conduits 17. For example, fluid collection device 12 may be in fluid communication with one or more of the fluid storage container 14 or the 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 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 vacuum source 16 either directly or indirectly.

[0019] 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 vacuum source 16. Accordingly, the 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 vacuum source 16. An additional conduit 17 may extend from the 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 vacuum source 16 may be disposed between the fluid collection device 12 and the fluid storage container 14.

[0020] The fluid collection device 12 is shaped and sized to be positioned adjacent to a female urethra. As described in more detail below, the fluid collection device 12 includes a fluid collection member and flanges positioned and equipped to attach to the skin of a user and align the fluid collection member in a selected portion of the anatomy of the user. Each said flange includes an adhesive for reversibly attaching to the skin of the user and is positioned on the fluid collection member to align an opening of the fluid collection member with the vagina between the labia of a female user.

[0021] The fluid collection member of the fluid collection device 12 includes 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. The fluid impermeable barrier also defines an opening extending therethrough from the external environment. The opening is configured to be positioned on the fluid collection member to be aligned adjacent to a female urethra. The fluid collection member of the fluid collection device 12 includes a fluid permeable membrane disposed within the fluid impermeable barrier. The fluid collection member of the fluid collection device 12 may include a 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. Exemplary fluid collection devices for use with the systems and methods herein are described in more detail below.

[0022] In examples, 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 fluid(s) 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 vacuum source 16. For example, the fluid storage container 14 may include a container in fluid communication with a first conduit section that is also in fluid communication with the fluid collection member of the fluid collection device 12. The container may be in fluid communication with a second section of the conduit 17 that is also in fluid communication with a vacuum source. In such examples, the 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 vacuum source 16.

[0023] In some examples, the vacuum source 16 may include a portable vacuum source. In examples, the portable vacuum source 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 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.

[0024] The vacuum source 16 may include one or more of a vacuum line plumbed into patient care facility, 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 vacuum source 16 may provide a vacuum or suction to remove fluid from the fluid collection member of the fluid collection device 12. In examples, the 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 vacuum source 16 (e.g., portable vacuum source) may be sized and shaped to fit outside of, on, or within the fluid collection device 12. For example, the vacuum source 16 (e.g., portable vacuum source) may include one or more miniaturized pumps or one or more micro pumps. The 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 vacuum source 16. It should be understood that the 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.

[0025] FIG. 2A is an isometric view of a fluid collection device 100, according to an embodiment. The fluid collection device 100 includes a fluid collection member 101 and flanges 140 extending from the fluid collection member 101. The fluid collection member 101 is substantially cylindrical, for complementing or contouring to the vaginal region of a female subject. The fluid collection member 101 includes a fluid impermeable barrier 102, wicking material 115, and a conduit 108. The wicking material 115 is disposed at least partially within the fluid impermeable barrier 102. The conduit 108 may be at least partially disposed with wicking material 115.

[0026] The fluid impermeable barrier 102 at least partially defines at least a portion of an outer surface of the fluid collection member 101. The fluid impermeable barrier 102 at least partially defines a chamber 104 therein (e.g., interior region of the fluid collection member 101) and an opening 106. The opening 106 is formed in and extends through the fluid impermeable barrier 102, thereby enabling fluid(s) to enter the chamber 104 from outside of the fluid collection member 101 of the fluid collection device 100. The opening 106 is configured to be positioned adjacent to a female urethra, between the labia majora of a female user.

[0027] The fluid impermeable barrier 102 may also temporarily retain or store fluid(s) in the chamber 104. 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, polyurethane, a polycarbonate, polyvinyl chloride, latex, silicone, etc.), a metal film, another suitable material, or combinations thereof. As such, the fluid impermeable barrier 102 may prevent at least some of the fluid(s) from exiting the portions of the chamber 104 that are spaced from the opening 106.

[0028] In an embodiment, the fluid impermeable barrier 102 can be air permeable and fluid impermeable. In such an embodiment, the fluid impermeable barrier 102 can be formed of a hydrophobic material that defines a plurality of pores. In an example, one or more portions of at least an outer surface of the fluid impermeable barrier 102 can be formed from a soft and / or smooth material thereby reducing chafing of the skin of the user. 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.

[0029] The wicking material 115 is disposed at least partially within the fluid impermeable barrier 102. The wicking material 115 may include permeable material designed to wick or allow fluid to pass therethrough. 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 not include absorption into the wicking material. The wicking material 115 may collect the fluid that travels through the opening 106. The wicking material 115 may include more than one material, such as a plurality of materials. The plurality of materials may include a plurality of layers concentrically disposed within one another. The concentrically disposed layers of wicking materials may exhibit a gradient of wicking, such as where the innermost wicking material includes the greatest or least wicking ability of the plurality of materials.

[0030] In examples, the wicking material 115 may include one or more of a fluid permeable support (FIGS. 3-8) or a fluid permeable membrane 118. For example, the fluid collection member 101 of the fluid collection device 100 can include a fluid permeable membrane 118 disposed in the chamber 104. The fluid permeable membrane 118 can cover at least a portion (e.g., all) of the opening 106. The fluid permeable membrane 118 can be configured to wick any fluid away from the opening 106, thereby preventing the fluid from escaping the chamber 104. The fluid permeable membrane 118 can also wick the fluid generally towards an interior of the chamber 104, as discussed in more detail below. The fluid permeable membrane 118 can include any material that can wick the fluid. For example, the fluid permeable membrane 118 can include fabric, such as a gauze (e.g., a silk, linen, 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). In some examples, the fluid permeable membrane 118 can include an open cell foam. Forming the fluid permeable membrane 118 from gauze, soft fabric, and / or smooth fabric can reduce chafing caused by the fluid collection device 100.

[0031] The fluid collection device 100 can include a fluid permeable support 120 (FIGS. 3-8 ) disposed in the chamber 104. The fluid permeable support 120 may support the fluid permeable membrane 118 since the fluid permeable membrane 118 can be formed from a foldable, flimsy, or otherwise easily deformable material. For example, the fluid permeable support 120 can be positioned such that the fluid permeable membrane 118 is disposed between the fluid permeable support and the fluid impermeable barrier 102. As such, the fluid permeable support 120 can support and maintain the position of the fluid permeable membrane 118. The fluid permeable support 120 can be formed from any fluid permeable material that is less deformable than the fluid permeable membrane 118. For example, the fluid permeable support 120 can include a porous nylon structure or an open cell foam. In embodiments, the fluid permeable support can be omitted from the fluid collection device 100.

[0032] In some embodiments, the wicking material 115 (e.g., one or more of the fluid permeable membrane 118 or the fluid permeable support) can at least substantially completely fill portions of the chamber 104 that are not occupied by the conduit 108. For example, the wicking material 115 may fill the portions of the chamber 104 that are not occupied by the conduit 108. In some examples, the fluid permeable membrane 118 and the fluid permeable support may not substantially completely fill the portions of the chamber 104 that are not occupied by the conduit 108. In such examples, the fluid collection device 100 may include the reservoir (e.g., void space) disposed in the chamber 104. The reservoir may include a void space between the wicking material in the chamber 104 and the interior surface of the fluid impermeable barrier 102. At least some of the fluid absorbed by the wicking material 115 may drain out of the wicking material 115 and collect in the reservoir.

[0033] The fluid collection member 101 of the fluid collection device 100 includes conduit 108 that is partially disposed in the chamber 104. 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 examples, the conduit 108 may include silicon or latex. The conduit 108 (e.g., a tube) includes an inlet at a first end region and an outlet at a second end region positioned downstream from the inlet. The conduit 108 places an interior region of the chamber 104 in fluid communication with one or more of the fluid storage container (FIG. 1) or the vacuum source (FIG. 1). The fluid is removed from the chamber 104 via the conduit 108. As suction or vacuum force is applied or formed in the conduit 108 by the vacuum source (FIG. 1), the fluid in the chamber 104 may be drawn into the inlet and out of the fluid collection member 101 via the conduit 108.

[0034] In examples, the conduit 108 may be disposed in an innermost or gravimetrically low spot in the chamber 104. For example, the conduit 108 may extend far enough into the chamber 104 to position the inlet in a gravimetrically low spot of the chamber 104 (e.g., fluid reservoir within the interior of the fluid collection member 101).

[0035] The fluid collection member 101 and components thereof may be deformable (e.g., bendable) responsive to pressure applied thereto. For example, the fluid collection member 101 and the components thereof may bend to conform to the surface of the user, such as when disposed between a garment and the user. In examples, the fluid collection member 101 may bend when disposing proximate to the urethra (e.g., between the labia) when undergarments are pulled on over the fluid collection member 101.

[0036] Each flange 140 extends from the fluid collection member 101. The flange includes a flange body 142 and an adhesive member 144 disposed on the flange body 142. The flange 140 includes 2 or more flanges (e.g., 4 flanges). The flange 140 exhibits a first flange body extending a first direction away from the fluid collection member 101 and a second flange body extending away from the fluid collection member 101 in a second direction, wherein the first and second directions are substantially opposite one another (e.g., at least 120° apart). Each flange 140 extends along less than 60% of the longitudinal length of fluid collection member 101. For example, the flange 140 may have a width, as viewed parallel to the plane B-B, of least 5% (e.g., at least 10%, at least 20%, at least 30%, at least 40%, at least 50%) of the longitudinal length of the fluid collection member 101. In examples, the width of the flange 140 may be at least 1 cm, such as 2 cm, 5 cm, 10 cm, 15 cm, 20 cm, 30 cm, or in a range between any combination of the foregoing. The flange 140 (e.g., flange body 142) may extend at least 1 cm away from the fluid collection member 101, such as 1 cm, 3 cm, 5 cm, 10 cm, 15 cm, 20 cm, 25 cm, 30 cm, or in a range between any combination of the foregoing, away from the fluid collection member 101.

[0037] In examples, the flange body 142 of the flange 140 may be formed of the same material as the fluid impermeable barrier 102. In examples, the flange body 142 of the flange 140 may be formed from one or more of cloth, paper, plastic, or any other material suitable for deforming responsive to pressure applied thereto and able to withstand moisture without breaking down. For example, the flange body 142 may be formed from thermoplastic elastomer, polyethylene, polyvinyl chloride, ethylene vinyl acetate, polytetrafluoroethylene, latex, silicon, fabric, woven cloth, etc. In examples, the conduit 108 may include silicon or latex. The flange body 142 of the flange 140 may be flexible and may conform to manipulation or movement by a user. The flange body 142 may exhibit any of the dimensions disclosed above for the flange 140.

[0038] The flange body 142 has the adhesive member 144 disposed thereon, such as at a distal portion thereof (e.g., distal from the fluid collection member 101). The adhesive member 144 may be affixed to the flange body 142 by mechanical means such as a staple(s), a clip, hook and loop fasteners, etc.; may be affixed by an adhesive; or may be integrally formed in the flange body 142. The adhesive member 144 is positioned on the flange body 142 in a position effective to allow the adhesive to be applied to the skin of the user to maintain a position of the fluid collection member 101 with respect to one or more anatomical features (proximate to the female urethra between the labia) of the user. In particular, the adhesive member 144 may be positioned on the flange body 142 to allow the flange(s) 140 to adhere to the inner thigh of a user and maintain a position of the associated fluid collection member 101 between the labia of the user 190. In examples, the adhesive member 144 may be flexible or otherwise configured to conform to the anatomical features of the user and accommodate movement of the user.

[0039] FIG. 2B is a front view of a user 190 with the fluid collection device 100 positioned for use. The user 190 may be a female and the fluid collection device 100 may be positioned for use (e.g., collecting urine or other bodily fluids from the vagina). The flanges 140 may be disposed on the fluid collection member 101 in a position to locate the fluid collection member 101 between the labia 192 when the flange 140 is adhered to the inner thigh 194 of the user 190. The conduit 108 may be in fluid communication with the fluid storage container or vacuum pump (not shown) to remove any collected fluid(s) from the fluid collection device 100.

[0040] Returning to FIG. 2A, the flange body 142 includes the adhesive member 144 disposed thereon. For example, the adhesive member 144 may be facing upward on the flange body 142 (e.g., in the general direction of the fluid collection member 101). In some examples, the flange 140 may additional or alternatively include the adhesive member 144 facing downward on the flange body 142. In examples, the adhesive member 144 may be located on a distal portion of the flange body 142 (e.g., distal from the fluid collection member 101). In examples, the adhesive member 144 may cover at least 5% of the surface area of the flange body 142, such as 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, or ranges between any combination of the foregoing, of the surface area of the flange body 142.

[0041] In examples, the adhesive member 144 may include a glue, contact adhesive, epoxy, hydrogel adhesive, tape, or other adhesive suitable for attaching the flange to skin or fabric. For example, the adhesive may include an acrylate (e.g., methacrylate or epoxy diacrylate) or any other adhesive suitable for use on bandages.

[0042] The cross-sectional profiles of the fluid collection devices disclosed herein may vary. For example, a longitudinal cross section is taken along the plane A-A and an axial cross section may be viewed along the plane B-B in FIG. 2A.

[0043] FIG. 3 is a schematic cross-sectional view of the fluid collection device 100 taken along the plane A-A of FIG. 2A, according to an embodiment. The fluid collection device 100 is an example of a female fluid collection device 100 sized, shaped, and otherwise configured to receive fluid(s) from a female user. The fluid collection device 100 includes the fluid collection member 101 and the flange 140. The fluid collection member 101 includes the fluid impermeable barrier 102. The fluid impermeable barrier 102 at least partially defines the chamber 104 (e.g., interior region) and the opening 106. The opening 106 is formed in and extends through the fluid impermeable barrier 102, thereby enabling fluid(s) to enter the chamber 104 from outside of the fluid collection device 100. The opening 106 is configured to be positioned adjacent to a female urethra. The opening 106 can be positioned on an upward facing portion of the fluid collection member 101 (e.g., region substantially opposite the flanges 140). The fluid collection device 100 also includes 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 first end region and an outlet 112 at a second end region positioned downstream from the inlet 110. The conduit 108 places the chamber 104 in fluid communication with the fluid storage container (not shown) or the vacuum source (not shown).

[0044] In the illustrated embodiment, the conduit 108 is at least partially disposed in the chamber 104. The conduit 108 extends into the fluid impermeable barrier 102 from the first end region (e.g., proximate to the outlet 112) and extends 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. The fluid collected in the fluid collection member 101 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 to by having one or more of a diameter or wall thickness that allows the conduit to be flexible.

[0045] In use, the fluid collection member 101 is positioned proximate to the female urethra (between the labia) and urine may enter the chamber 104 of the fluid collection member 101 via the opening 106. The fluid collection member 101 receives the fluid(s) into the chamber 104 via the opening 106. For example, the opening 106 can exhibit an elongated shape that is sized and positioned 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 mons pubis). The opening 106 can exhibit an elongated shape since the space between the legs of a female is relatively small when the legs of the female of closed thereby only permitting the flow of the fluid(s) along a path that corresponds to the elongated shape of the opening 106. The longitudinal axis or dimension of the fluid collection device refers to the axis or dimension that is parallel to largest dimension of the device, such as axially along a cylindrical device as show in FIG. 2A. 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 member 101, such as about 25%, 30%, 40%, 50%, 60%, 75%, 85%, 100% or ranges between any combination of the foregoing, of the circumference of the fluid collection member 101. The opening 106 can exhibit a width that is greater than 50% of the circumference of the fluid collection member 101 since the vacuum (e.g., suction) through the conduit 108 pulls the fluid into the conduit 108. The opening 106 is vertically oriented (e.g., having a major axis parallel to the longitudinal axis of the device 100). In an example, one or more portions of the fluid impermeable barrier 102 can be configured to be attached to the individual, such as adhesively attached (e.g., with a hydrogel adhesive) to the individual. According to an embodiment, a suitable adhesive for the impermeable barrier (or flanges) is a hydrogel layer.

[0046] The fluid collection member 101 includes the wicking material 115 disposed in the chamber 104. The wicking material 115 may include one or more of the fluid permeable membrane 118 and the fluid permeable support 120, each disposed in the chamber 104. The fluid permeable membrane 118 can cover at least a portion (e.g., all) of the opening 106. The fluid permeable membrane 118 can be configured to wick any fluid away from the opening 106 thereby preventing the fluid from escaping the chamber 104. The fluid permeable membrane 118 can also wick the fluid generally towards an interior of the chamber 104, as discussed in more detail below. The fluid permeable membrane 118 can include any material that can wick the fluid. For example, the fluid permeable membrane 118 can include fabric, such as a gauze (e.g., a silk, linen, polymer based materials such as polyester, or cotton gauze), another soft fabric, or another smooth fabric. Forming the fluid permeable membrane 118 from gauze, soft fabric, and / or smooth fabric can reduce chafing caused by the fluid collection member 101.

[0047] The fluid permeable support 120 may be disposed in the chamber 104, such as concentrically within the fluid permeable membrane 118. The fluid permeable support 120 may be formed from material that is more rigid (e.g., less deformable) than the fluid permeable membrane 118, such as any of the materials disposed herein for a fluid permeable membrane. For example, the fluid permeable support 120 can include a porous nylon structure. The fluid permeable support 120 is configured to support the fluid permeable membrane 118 since the fluid permeable membrane 118 can be formed from a foldable, flimsy, or otherwise easily deformable material. For example, the fluid permeable support 120 can be positioned such that the fluid permeable membrane 118 is disposed between the fluid permeable support 120 and the fluid impermeable barrier 102. As such, the fluid permeable support 120 can support and maintain the position of the fluid permeable membrane 118. In an embodiment, the fluid permeable support 120 can be omitted from the fluid collection member 101.

[0048] In an embodiment, the fluid permeable membrane 118 and the fluid permeable support 120 can at least substantially completely fill the portions of the chamber 104 that are not occupied by the conduit 108. In another example, the fluid permeable membrane 118 and the fluid permeable support 120 may not substantially completely fill the portions of the chamber 104 that are not occupied by the conduit 108. In such an example, the fluid collection device 100 includes the reservoir 122 disposed in the chamber 104. The reservoir 122 is a substantially unoccupied portion of the chamber 104. The fluid(s) that is in the chamber 104 can flow through the fluid permeable membrane 118 and / or fluid permeable support 120 to the reservoir 122. The reservoir 122 can store at least some of the fluid(s) therein.

[0049] The fluid impermeable barrier 102 can store fluid(s) in the reservoir 122. The reservoir 122 may be disposed in any portion of the interior region of the chamber 104. For example, the fluid reservoir 122 may be positioned in the second end region of the chamber 104.

[0050] In an example, the reservoir 122 can be located at the portion of the chamber 104 that is closest to the inlet 110 (e.g., the second end region). However, the reservoir 122 can be located at different locations in the chamber 104. For example, the reservoir 122 can be located at the end of the chamber 104 that is closest to the outlet 112. In another example, fluid collection device 100 can 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 support 120 is spaced from at least a portion of the conduit 108 and the reservoir 122 can be the space between the fluid permeable support 120 and the conduit 108.

[0051] The fluid impermeable barrier 102, the fluid permeable membrane 118 and the fluid permeable support 120 can be configured to have the conduit 108 at least partially disposed in the chamber 104. For example, at least one of the fluid permeable membrane 118 and the fluid permeable support 120 can be configured to form a space that accommodates the conduit 108. In another example, the fluid impermeable barrier 102 can define an aperture 124 sized to receive the conduit 108 (e.g., at least one tube). The at least one conduit 108 can be disposed in the chamber 104 via the aperture 124 in the first end region of the device 100. The aperture 124 can 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 fluid(s) from escaping the chamber 104.

[0052] As previously discussed, the conduit 108 is configured to be coupled to, and at least partially extend between, one or more of the fluid storage container (not shown) and the vacuum source (not shown). In an example, the conduit 108 is configured to be directly connected to the vacuum source (not shown). In such an example, the conduit 108 can extend from the fluid impermeable barrier 102 by at least 30 cm (one foot), at least 60 cm (two feet), at least 90 cm (three feet), or at least 180 cm (six feet). In another example, the conduit 108 is configured to be indirectly connected to at least one of the fluid storage container (not shown) and the vacuum source (not shown). 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. Patent Nos. 6,117,163; 6,123,398; and 8,211,063.

[0053] The inlet 110 and the outlet 112 are sized, positioned, or otherwise configured to place (e.g., directly or indirectly) the vacuum source (not shown) in fluid communication with the chamber 104 (e.g., the reservoir 122). In an example, the inlet 110 and / or the outlet 112 can form a male connector. In another example, the inlet 110 and / or the outlet 112 can form a female connector. In an example, the inlet 110 and / or the outlet 112 can include ribs that are configured to facilitate secure couplings. In an example, the inlet 110 and / or the outlet 112 can form a tapered shape. In an example, the inlet 110 and / or the outlet 112 can include a rigid or flexible material.

[0054] Locating the inlet 110 at or near a gravimetrically low point of the chamber 104 enables the conduit to receive more of the fluid(s) than if inlet 110 was located elsewhere and reduce the likelihood of pooling (e.g., pooling of the fluid(s) can cause microbe growth and foul odors). For instance, the fluid(s) in the fluid permeable membrane 118 and the fluid permeable support 120 can flow in any direction due to capillary forces. However, the fluid(s) may exhibit a preference to flow in the direction of gravity, especially when at least a portion of the fluid permeable membrane 118 and / or the fluid permeable support 120 is saturated with the fluid(s).

[0055] As the vacuum source (FIG. 1) applies a vacuum / suction in the conduit 108, the fluid(s) in the chamber 104 (e.g., at the second end region such as in the reservoir 122) may be drawn into the inlet 110 and out of the fluid collection member 101 of the fluid collection device 100 via the conduit 108.

[0056] In an example, the conduit 108 is configured to be at least insertable into the chamber 104. In such an example, the conduit 108 can include one or more markers (not shown) on an exterior thereof that are configure to facilitate insertion of the conduit 108 into the chamber 104. For example, the conduit 108 can 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 configured to be disposed in or adjacent to the reservoir 122. In another example, the conduit 108 can include one or more markings thereon that are configured to facilitate correct rotation of the conduit 108 relative to the chamber 104. In an example, the one or more markings can include a line, a dot, a sticker, or any other suitable marking. In some examples, the conduit may be frosted or opaque (e.g., black) to obscure visibility of the fluid(s) therein.

[0057] In an example, one or more components of the fluid collection device 100 can 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 can include an antimicrobial coating, such as a nitrofurazone or silver coating. The antimicrobial material can inhibit microbial growth, such as microbial growth due to pooling or stagnation of the fluid(s). In an example, one or more components (e.g., impermeable barrier 102, conduit 108, etc.) of the fluid collection device 100 can include an odor blocking or absorbing material such as a cyclodextrine containing material or a thermoplastic elastomer (TPE) polymer.

[0058] The flanges 140 are disposed on a lower portion of the fluid collection member 101 (e.g., substantially opposite the opening 106). For example, the flanges 140 may be affixed to or integrally formed in the fluid impermeable barrier 102.

[0059] FIG. 4 is a schematic cross-sectional view of the fluid collection device 400 taken along the plane A-A of FIG. 2A. The fluid collection device 400 may include the portable vacuum source 330 disposed therein. Except as otherwise disclosed herein, the fluid collection device 400 can be the same as or substantially similar to the fluid collection device 100 of FIG. 2A, in one or more aspects. The fluid collection device 400 includes fluid collection member 401 and the at least one flange 140. The fluid collection member 401 may be similar or identical to the fluid collection member 101 in one or more aspects, such as including one or more of the fluid impermeable barrier 102 that defines the chamber 104 and the opening 106, the wicking material 115, the fluid permeable membrane 118, the fluid permeable support 120, and the reservoir 122 , or the conduit 108. The fluid collection device 400 includes the portable vacuum source 330 disposed therein. The portable vacuum source 330 may be similar or identical to the vacuum source 16 as disclosed herein, in one or more aspects. The portable vacuum source 330 may be sized to fit on or within the fluid collection device. The portable vacuum source may be sized and shaped for a person to carry. As shown, the portable vacuum source 330 may be at least partially disposed within the fluid impermeable barrier 102. While a portable vacuum source 330 is depicted in FIG. 4, a fixed vacuum source (e.g., vacuum line) may alternatively or additional be used with the fluid collection device 400.

[0060] The fluid collection device 400 includes the conduit 108 that is at least partially disposed in the chamber 104. For example, the wicking material 115 (e.g., the fluid permeable membrane 118, the fluid permeable support 120) may fill a portion of the chamber 104 and leave a portion vacant thereby forming the reservoir 122 between the wicking material 115 and the fluid impermeable barrier 102. The conduit 108 can include one or more walls that define an inlet 110 and the outlet 112. The inlet 110 enables at least some of the fluid(s) that is present in the chamber 104 to enter the conduit 108. In an example, the conduit 108 can be configured to have the inlet 110 located at, near, or spaced at a gravimetrically low point of the chamber 104. In an example, the conduit 108 can be configured to have the at least one inlet 110 disposed in or adjacent to the reservoir 122. As shown the conduit 108 extends through at least a portion of the chamber 104, such as longitudinally through at least a portion of the wicking material 115 in a concentrically central region fluid collection member 115.

[0061] The conduit 108 can be in fluid communication with the interior region (e.g., reservoir 122) of the chamber 104 via the fluid impermeable barrier 102. As such, the fluid impermeable barrier 102 can define the aperture 124. In an example, as illustrated, the aperture 124 enables the conduit 108 to extend outwardly from the chamber 104 when the conduit 108 is only partially disposed in the chamber 104. In examples, the conduit 108 may include a plurality of separate sections. For example and as shown, the conduit 108 may include a first section A and section B. The first section A may include the inlet 110 extending from the distal end (e.g., first end region) to the portable vacuum source 330 and the B section may extend from the portable vacuum source 330 out of the aperture 124, such as to a fluid storage container (not shown).

[0062] The portable vacuum source 330 may include any of the portable vacuum pumps disclosed herein. For example, the portable vacuum source 330 may include a manual 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 330 may be sized to fit in the chamber 104 inside of the fluid impermeable barrier 102. In examples, the portable vacuum source 330 may sealed in a fluid tight housing or container. The portable vacuum source 330 may apply a vacuum (e.g., suction) in the A section of the conduit 108 effective to suction fluid from the chamber 104. The fluid may travel through the A section to the B section (e.g., through the portable vacuum source 330) and out of the fluid collection device 300 via the B section by flow induced by the vacuum or suction applied by the portable vacuum source 330. For example, the portable vacuum source 330 may include a centrifugal pump and an impeller therein may draw the fluid from the chamber 104 via the inlet 110 and force the fluid out of the chamber 104 via the B section of the conduit 108. Each of the A section and the B section of the conduit 108 may be in fluid communication with (e.g., sealed) the portable vacuum source 330. In some examples, the portable vacuum source 330 and the conduit 108 can be integrally formed together (e.g., exhibit single piece construction).

[0063] FIG. 5 is a schematic cross-sectional view of the fluid collection device 500 taken along the plane A-A of FIG. 2A. The fluid collection device 500 may include the portable vacuum source 330 disposed thereon. Except as otherwise disclosed herein, the fluid collection device 500 can be the same as or substantially similar to the fluid collection device 100 of FIG. 2A, in one or more aspects. The fluid collection device 500 includes fluid collection member 501 and the flanges 140. The fluid collection member 501 may be similar or identical to the fluid collection member 101 in one or more aspects, such as including one or more of the fluid impermeable barrier 102 that defines the chamber 104 and the opening 106, the wicking material 115, the fluid permeable membrane 118, the fluid permeable support 120, and the reservoir 122 , or the conduit 108. The fluid collection member 501 of the fluid collection device 500 includes the portable vacuum source 330 disposed thereon. The portable vacuum source 330 may be attached to the fluid collection device 500 at or on the fluid impermeable barrier 102. While a portable vacuum source 330 is depicted in FIG. 5, a fixed vacuum source (e.g., vacuum line) may alternatively or additional be used with the fluid collection device 500.

[0064] The fluid collection device 500 includes the conduit 108 that is at least partially disposed within the fluid collection member 501. For example, the wicking material 115 (e.g., the fluid permeable membrane 118, the fluid permeable support 120) may fill a portion of the chamber 104 and leave a portion vacant thereby forming the reservoir 122 between the wicking material 115 and the fluid impermeable barrier 102. As shown the conduit 108 extends through at least a portion of the chamber 104, such as longitudinally through at least a portion of the wicking material 115 in a concentrically central region fluid collection member 115 to the reservoir 122. The conduit 108 may extend through the wicking material 115 to the reservoir 122. The conduit 108 can include one or more walls that define an inlet 110 and the outlet 112. The inlet 110 enables at least some of the fluid(s) that is present in the chamber 104 to enter the conduit 108. In an example, the conduit 108 can be configured to have the inlet 110 located at, near, or spaced at a gravimetrically low point of the chamber 104. In an example, the conduit 108 can be configured to have the at least one inlet 110 disposed in or adjacent to the reservoir 122.

[0065] The conduit 108 can be in fluid communication with the interior region of the chamber 104 via the fluid impermeable barrier 102. As such, the fluid impermeable barrier 102 can define the aperture 124. In an example, as illustrated, the aperture 124 enables the conduit 108 to extend outwardly from the chamber 104 when the conduit 108 is only partially disposed in the chamber 104. In examples, the conduit 108 may include a plurality of separate sections. For example and as shown, the conduit 108 may include the first section A and the second section B. The first section A may include the inlet 110 extending from the distal end (e.g., first end region), out of the aperture 124, to the portable vacuum source 330 mounted thereto. The portable vacuum source 330 may be mounted to the outer surface of the fluid collection device 400. The B section may be attached to and extend from the portable vacuum source 330, such as to a fluid storage container (not shown).

[0066] The portable vacuum source 330 may include any of the portable vacuum pumps disclosed herein such as a manual 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 330 may be sized to fit in the chamber 104 inside of the fluid impermeable barrier 102. In examples, the portable vacuum source 330 may sealed in a fluid tight housing or container. The portable vacuum source 330 may apply a vacuum (e.g., suction) in the A section of the conduit 108 effective to suction fluid from the chamber 104. The fluid may travel through the A section out of the fluid collection device 400 to the portable vacuum source 330. The fluid may be removed from the portable vacuum source 330 via the B section by flow induced by the vacuum or suction applied by the portable vacuum source 330. For example, the portable vacuum source 330 may include a centrifugal pump and an impeller therein may draw the fluid from the chamber 104 via the inlet 110 and suction the fluid out of the chamber 104 via the portable vacuum source 330 to the B section of the conduit 108. Each of the A section and the B section of the conduit 108 may be in fluid communication with (e.g., sealed) the portable vacuum source 330. In some examples, the portable vacuum source 330 and the conduit 108 (e.g., one or both of the A section or the B section) can be integrally formed together to exhibit single piece construction.

[0067] The fluid collection devices shown in FIGS. 2-5 are examples of female fluid collection devices that are configured to collect fluid(s) from females (e.g., collect urine from a female urethra). 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 fluid(s) 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., vacuum source or fluid storage container), or one or more valves to control the flow of fluid(s) in the systems and devices herein.

[0068] In an example, at least one of portion of the conduit 108 of the fluid collection devices or systems herein can be formed of an at least partially opaque material which can obscure the fluid(s) that is present therein. For example, the B section of the conduits 108 disclosed herein may be formed of an opaque material or translucent material while the A section may be formed of a transparent material or translucent material. In examples, the B 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 fluid(s) or issues that are inhibiting the flow of fluid(s) within the conduit 108.

[0069] In any of the example, 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 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 of the vacuum source (e.g., vacuum device with a programmable controller) 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 of the vacuum source to activate the vacuum source.

[0070] The cross-sectional shape of the fluid collection members disclosed herein may include any of various shapes or sizes. For example, the cross-sectional shape (along the plane B-B of FIG. 2A) may be substantially round (e.g., circular), elliptical, rectangular, triangular, irregular (e.g., having no specific shape), etc. FIGS. 6-8 are schematic cross-sectional views of female fluid collection devices taken along the plane B-B of FIG. 2, according to different embodiments.

[0071] FIG. 6 is a schematic cross-sectional view of the fluid collection device 100 taken along the plane B-B of FIG. 2A, according to an embodiment. The fluid collection device 100 includes the fluid collection member 101 and the at least one flange 140 extending therefrom. As shown, the fluid collection member 101 includes the fluid impermeable barrier 102, the wicking member 115 (e.g., the fluid permeable membrane 118 and the fluid permeable support 120), and the conduit 108, all concentrically arranged. As shown, the cross-sectional shape of the fluid collection member 101, and one or more components therein, may be generally round (e.g., circular or ellipsoid).

[0072] Each flange 140 may extend substantially tangentially from the fluid collection member 101 (e.g., the fluid impermeable barrier 102). The flanges 140 each extend from the fluid collection member 101 tangentially in substantially opposite directions from one another. "Substantially tangentially" may include flanges 140 that extend outwardly at an angle within 10% of 0° from an attachment point of the flange(s) on the outer surface of the fluid impermeable barrier. According to the invention, the flanges 140 attach to the fluid collection member 101 at a point substantially opposite the opening 106. The fluid collection member 101 may extend toward the user past the flanges 140. Such arrangements may allow the fluid collection member 101 to be positioned on the region of the female urethra, such as on or between the labia.

[0073] In examples, the flange bodies 142 may have the adhesive member 144 bound thereto on a surface thereof that generally faces the same direction as the opening 106. In some examples, the flanges 140 may alternatively or additionally include adhesive members 144 on the surface of the flange body 142 that face generally away from the opening 106. The adhesive members 144 allow the flange body 142 to be attached (e.g., temporarily adhered) to one or more skin surfaces of the subject that are adjacent to the urethra of the user, such as the thighs or pubic region. The adhesive members 144 secure and maintain the fluid collection device 100 in a position to collect fluid from the user, between the labia to collect urine from a female subject.

[0074] FIG. 7 is a schematic cross-sectional view of the fluid collection device 700 taken from a view along the plane B-B of FIG. 2A. The fluid collection device 100 includes the fluid collection member 101 and each flange 140 extending therefrom. As shown, the fluid collection member 101 includes the fluid impermeable barrier 102, the wicking member 115 (e.g., the fluid permeable membrane 118 and the fluid permeable support 120), and the conduit 108, all concentrically arranged. As shown, the cross-sectional shape of the fluid collection member 101, and one or more components therein, may be generally round (e.g., circular or ellipsoid).

[0075] Each flange 140 extends substantially away from the fluid collection member 101 (e.g., the fluid impermeable barrier 102). 2 flanges 140 each extend from the fluid collection member 101 (e.g., in a radial direction) from the fluid impermeable barrier 102 and in substantially opposite directions from one another. As shown, the flanges 140 attach to the fluid collection member 101 and radially extend therefrom in radially opposite directions. The fluid collection member 101 may extend toward the user past the flanges 140. Such arrangements allow the fluid collection member 101 to be positioned on the region of the female urethra, between the labia.

[0076] In examples, the flange bodies 142 may have the adhesive member 144 bound thereto on a surface thereof that generally faces the same direction as the opening 106. In some examples, the flanges 140 may alternatively or additionally include adhesive members 144 on the surface of the flange body 142 that face generally away from the opening 106. The adhesive members 144 may allow the flange body 142 to be attached (e.g., temporarily adhered) to one or more skin surfaces of the subject that are adjacent to the urethra of the user, such as the thighs or pubic region. The adhesive members 144 secure and maintain the fluid collection device 100 in a position to collect fluid from the user, between the labia to collect urine from a female subject.

[0077] The cross-sectional shape of the fluid collection member and the position(s) of the components therein may vary. FIG. 8 is a schematic cross-sectional view of the fluid collection device 800 taken from a view along the plane B-B of FIG. 2A. The fluid collection device 800 may be similar or identical to the fluid collection device 100, in one or more aspects. The fluid collection device 800 includes the fluid collection member 801 and the flanges 140 extending therefrom. The fluid collection member 801 may be similar or identical to the fluid collection member 101, in one or more aspects. For example, the fluid collection member 801 includes the fluid impermeable barrier 102, the wicking member 115 (e.g., the fluid permeable membrane 118 and the fluid permeable support 120), and the conduit 108. The cross-sectional shape of the fluid collection member 801 may be generally rectangular (e.g., with rounded corners) as shown, or elliptical. In such examples, the fluid collection member 801 may provide coverage (e.g., fluid absorption) of a larger surface area than the fluid collection member 101 (FIG. 6). In examples, the fluid impermeable barrier 102 may be shaped to provide a relatively wide cross-sectional shape. As shown, the fluid impermeable barrier 102 may form the chamber 104 having a gravimetrically low portion, such as in a V-notched or dished shape. The wicking material 115 may fill at least a portion of the chamber 104. For example, the fluid permeable support 120 may fill an interior portion of the chamber 104, and the fluid permeable member 118 may extend around at least a portion of the fluid permeable support 120. In examples, the fluid permeable support 120 may include region therein for accommodating the conduit 108. In examples, the conduit 108 may be disposed in the gravimetrically low point or region of the chamber 104. As shown, one or more of the conduit 108, fluid permeable member 118, or the fluid permeable support 120 may be non-concentrically disposed (e.g., not centered) in the fluid collection member 801 or fluid impermeable barrier 102.

[0078] Additional or alternative shapes for the fluid collection members are considered. For example, the fluid collection member may have a substantially triangular cross-sectional shape where a corner or apex of the triangle faces the user.

[0079] Each flange 140 extends substantially perpendicularly away from the fluid collection member 801 (e.g., the fluid impermeable barrier 102). 2 flanges 140 each extend from the fluid collection member 801 perpendicularly from the fluid impermeable barrier 102 and in substantially opposite directions from one another. As shown, the flanges 140 attach to the fluid collection member 801 in radially opposite directions. The fluid collection member 801 may extend toward the user past the flanges 140. Such arrangements allow the fluid collection member 801 to be positioned on the region of the female urethra, between the labia.

[0080] In examples, the flange bodies 142 may have the adhesive member 144 bound thereto on a surface thereof that generally faces the same direction as the opening 106. In some examples, the flanges 140 may alternatively or additionally include adhesive members 144 on the surface of the flange body 142 that face generally away from the opening 106. The adhesive members 144 may allow the flange body 142 to be attached (e.g., temporarily adhered) to one or more skin surfaces of the subject that are adjacent to the urethra of the user, such as the thighs or pubic region. The adhesive members 144 may secure and maintain the fluid collection device 100 in a position to collect fluid from the user, between the labia to collect urine from a female subject.

[0081] In some examples, the fluid collection devices herein may include more than one conduit therein. the more than one conduit may be disposed in a plurality of regions therein. In examples, conduit 108 may include a plurality of inlets.

[0082] FIG. 10 is a flow diagram of a non-claimed method 1000 to use any of the fluid collection devices, members, and / or fluid collection systems disclosed herein. The method 1000 can include act 1010, which recites "positioning an opening of a fluid collection device adjacent to a female urethra of a user, the opening defined by a fluid impermeable barrier of the fluid collection device." Act 1010 may be followed by act 1020, which recites "securing the fluid collection device to the user." Act 1020 may be followed by act 1030, which recites "receiving fluid from the female urethra into a chamber of the fluid collection device, the chamber of the fluid collection device at least partially defined by the fluid impermeable barrier."

[0083] Acts 1010, 1020, 1030 of the method 1000 are for illustrative purposes. For example, the act 1010, 1020, 1030 of the method 1000 can be performed in different orders, split into multiple acts, modified, supplemented, or combined. In an example, one or more of the acts 1010, 1020, 1030 of the method 1000 can be omitted from the method 1000. Any of the acts 1010, 1020, or 1030 can include using any of the fluid collection devices or systems disclosed herein.

[0084] Act 1010 recites "positioning an opening of a fluid collection device adjacent to a female urethra of a user, the opening defined by a fluid impermeable barrier of the fluid collection device." Act 1010 includes positioning the opening of a female fluid collection device such that the fluid permeable membrane of the female fluid collection device abuts or is positioned proximate to the female urethra. Positioning an opening of a fluid collection device adjacent to a female urethra of a user includes positioning opening of the fluid collection member of the fluid collection device between the labia. In examples the female fluid collection device may be similar or identical to the fluid collection device 100, 400, 500, 700, or 800 (FIGS. 2A-8), in one or more aspects.

[0085] Act 1020 recites, "securing the fluid collection device to the user." Securing the fluid collection device to the user includes affixing one or more flanges of the fluid collection device to the user or clothing of the user. Securing the fluid collection device to the user includes adhering the adhesion member of the at least one flange of the fluid collection device to the user. Securing the fluid collection device to the user includes adhering the adhesion member(s) of the at least one flange (e.g., flanges) of the fluid collection device to the user (or clothing). For example, securing the fluid collection device to the user can include adhering the adhesion member(s) of the at least one flange of the fluid collection device to the inner thigh(s) of a female user. Securing the fluid collection device to the user can include adhering the adhesion member of each flange of the fluid collection device to the garment (e.g., the underwear) of the user. For example, adhering the adhesion member of the flange of the fluid collection device to the garment may include adhering the flanges on or around the crotch (e.g., gusset) of underwear of the user. Securing the fluid collection device to the user may include securing the fluid collection device to the user to maintain the opening adjacent to, on, and over the urethra of the user, even when the user moves.

[0086] Act 1030 recites "receiving fluid from the female urethra into a chamber of the fluid collection device, the chamber of the fluid collection device at least partially defined by the fluid impermeable barrier." In examples, act 1030 can include retaining the fluid within the chamber, such as in a gravimetrically low point therein. Act 1030 includes wicking the fluid away from the opening using wicking material (e.g., fluid permeable membrane and a fluid permeable support). Act 1030 includes receiving the fluid into the chamber of the fluid collection device. Act 1030 includes flowing the fluid towards a portion of the chamber that is in fluid communication with an inlet of a conduit in fluid communication with a vacuum source. For instance, act 1030 can include flowing the fluid to a substantially unoccupied portion of the chamber (e.g., a reservoir), to a gravimetrically low point of the chamber, etc. The fluid can include one or more fluids, such as urine, liquid blood, sweat, etc. Receiving fluid from the female urethra into a chamber of the fluid collection device, the chamber of the fluid collection device at least partially defined by the fluid impermeable barrier includes wicking the fluid into the chamber via the fluid permeable membrane and fluid permeable support of the fluid collection device. For example, wicking the fluid into the chamber via the fluid permeable membrane and fluid permeable support may include wicking urine into the reservoir in the fluid collection device.

[0087] The method 1000 may include removing at least some of the fluid from the fluid collection device. For example, removing at least some of the fluid from the fluid collection device may include removing the fluid from within the chamber of the fluid collection device. Such removal may include applying suction with a vacuum source effective to suction the fluid from the chamber via a conduit disposed therein (which conduit may be in fluid communication with the vacuum source). In examples, removing fluids from the fluid collection device by applying suction with a vacuum source effective to suction (e.g., vacuum) the fluid from the chamber via a conduit disposed therein include using any of the vacuum sources disclosed herein, such as a portable vacuum source. In an example, applying suction can include activating the vacuum source (e.g., portable suction device) in fluid communication with the inlet of the conduit in the fluid collection device. In examples, activating the vacuum source in fluid communication with the inlet of the conduit in the fluid collection device can include supplying power to the vacuum source by one or more of flipping an on / off switch, pressing a button, opening a valve, connecting the fluid collection device into a vacuum line, plugging a portable vacuum source into a power outlet, putting batteries into the portable vacuum source, etc. In examples, the vacuum source may include a hand operated vacuum pump and applying suction with a vacuum source may include manually operating the hand operated vacuum pump effective to suction the fluid from the chamber via the conduit disposed therein that is in fluid communication with the (portable) vacuum source. In examples, the vacuum source may include a plumbed vacuum line and applying suction with a vacuum source may include manually connecting to the plumbed vacuum line to the fluid collection device (e.g., the conduit) or opening a valve therebetween effective to suction the fluid from the chamber via the conduit disposed therein.

[0088] In examples, applying suction with a vacuum source effective to suction the fluid from the chamber via a conduit disposed therein and in fluid communication with the vacuum source can be effective to remove at least some fluid (e.g., urine) from the chamber (e.g., interior region) of the fluid collection device. In examples, applying suction with a vacuum source effective to suction the fluid from the chamber via a conduit disposed therein and in fluid communication with the vacuum source can be effective to transfer at least some of the fluid from the chamber of the fluid collection device to a fluid storage container (e.g., a bottle or bag). In some examples, applying suction with a vacuum source effective to suction the fluid(s) from the chamber may include removing fluid from one or more of a reservoir, fluid permeable support, or fluid permeable membrane of the fluid collection device.

[0089] In examples, the vacuum source (e.g., suction device) may disposed on or within the fluid collection device and applying suction with the vacuum source may include activating the vacuum source. In examples, the vacuum source may be spaced from the fluid collection device and applying suction with the vacuum source may include activating the vacuum source, such as a portable vacuum source.

[0090] In examples, applying suction with a vacuum source effective to suction the fluid from the chamber via a conduit disposed therein and in fluid communication with the vacuum source may include detecting moisture in the chamber (e.g., via one or more moisture sensors) and responsive thereto, activating the vacuum source to provide suction in the chamber. The control of the vacuum source responsive to the signals indicating that moisture or a level thereof is present in the chamber can be automatic, such as via a controller, or may merely provide an indication that a level of moisture is present that may necessitate removal of fluid from the chamber of the fluid collection device. In the latter case, a user may receive the indication and activate the vacuum source such as a pump.

[0091] In an example, the method 1000 can include collecting the fluid that is removed from the fluid collection device, such as into a fluid storage container that is spaced from the fluid collection device and in fluid communication with the conduit. The fluid storage container can include any of the fluid storage containers disclosed herein.
