Description

[0001] Cross-reference to related applications

[0002] This application claims priority to U.S. Provisional Application No. 63 / 076,032, filed September 9, 2020, the disclosure of which is incorporated herein by reference in its entirety. Background Technology

[0003] An individual's mobility may be limited or impaired, making the typical urination process challenging or impossible. For example, an individual may have undergone surgery or suffered a disability that impairs mobility. Another example is an individual facing limited travel conditions, such as pilots, drivers, and workers in hazardous areas. Furthermore, fluid collection from the individual may be necessary for monitoring or clinical testing.

[0004] Bedpans and catheters (such as Foley catheters) can be used to address some of these situations. However, bedpans and catheters present several associated problems. For example, bedpans can easily cause discomfort, splashing, and other hygiene issues. Catheters can be uncomfortable, painful, and may lead to urinary tract infections.

[0005] Therefore, users and manufacturers of fluid collection devices are constantly seeking new and improved devices, systems and methods for collecting urine. Summary of the Invention

[0021] The embodiments disclosed herein relate to devices, systems, and methods of using fluid collection devices and systems. The fluid collection devices, systems, and methods described herein include protrusions on the fluid collection device to help position and retain the fluid collection device, and to prevent urine leakage at the junction of the fluid collection device and the wearer's tissue.

[0022] The fluid collection device described herein includes a fluid-impermeable barrier that at least partially defines a chamber. The fluid-impermeable barrier also defines an opening extending through it, configured to be located adjacent to the female urethra. The fluid collection device includes a porous material at least partially disposed within the chamber and having protrusions positioned between the labia majora near the urethra. The fluid collection device may also include a conduit disposed within the chamber. The fluid collection device disclosed herein is configured to collect fluid from an individual. The fluid collected by the fluid collection device may include at least one of urine, vaginal secretions, blood, sweat, and other bodily fluids.

[0023] By providing a porous material with raised portions, the fluid collection device is held in place on the wearer by the raised portions positioned between the labia. Furthermore, the raised portions of the porous material tightly engage with the wearer's urethra to prevent fluid leakage from the user. Therefore, the size and shape of the fluid collection device disclosed herein are designed to collect fluid from an individual while preventing leakage and providing a secure fit on the wearer.

[0024] The fluid collection device disclosed herein is configured for use in a fluid collection system to collect and remove fluid from the wearer of the fluid collection device.

Figure 1C It is based on at least some implementation methods Figure 1A An exploded view of the fluid collection device. Figure 1D It is based on at least some implementation methods Figure 1A A cross-sectional view of the fluid collection device taken along the BB plane. The fluid collection device 100 is an embodiment of a female fluid collection device for receiving and collecting fluid from a woman. The fluid collection device 100 includes a fluid-impermeable barrier 102, a porous material 115 at least partially disposed within a chamber 104 within the fluid-impermeable barrier 102, and an optional conduit 108 at least partially disposed within the chamber 104. The porous material 115 includes a protrusion 130 extending from the chamber 104. During use, by mounting the protrusion 130 between the wearer's labia (e.g., the labia majora) near the wearer's urethra, the protrusion 130 helps to position and hold the fluid collection device in the wearer's ideal position and prevent leakage from the device.

[0026] The fluid-impermeable barrier 102 at least partially defines a chamber 104 (e.g., an internal region) and an opening 106. For example, the inner surface 103 of the fluid-impermeable barrier 102 at least partially defines the chamber 104 within the fluid collection device 100. The fluid-impermeable barrier 102 retains fluid in the chamber 104 at least temporarily. The fluid-impermeable barrier 102 can be formed of any suitable fluid-impermeable material (one or more materials), such as fluid-impermeable polymers (e.g., silicone, polypropylene, polyethylene, polyethylene terephthalate, thermoplastic elastomers, polycarbonate, etc.), metal films, natural rubber, other suitable materials, or combinations thereof. Therefore, the fluid-impermeable barrier 102 substantially prevents fluid from passing through it.

[0027] In one embodiment, the fluid-impermeable barrier 102 may be breathable but impermeable to liquids. In such an embodiment, the fluid-impermeable barrier 102 may be formed of a hydrophobic material defining a plurality of pores that are breathable but impermeable to liquids. In one embodiment, at least one or more portions of at least the outer surface of the fluid-impermeable barrier 102 may be formed of a soft and / or smooth material, thereby reducing abrasion.

[0028] In some embodiments, the fluid-impermeable barrier 102 may be tubular (openings omitted), such as substantially cylindrical (as shown), rectangular, prismatic, or flat tube. The fluid-impermeable barrier 102 may be sized to fit between the legs of a female user. During use, the outer surface 105 of the fluid-impermeable barrier 102 may come into contact with the wearer.

[0029] Opening 106 provides an entry path for fluid into chamber 104. Opening 106 may be defined by a fluid-impermeable barrier 102, such as by the inner edge of the fluid-impermeable barrier 102. For example, opening 106 is formed in the fluid-impermeable barrier 102 and extends through the fluid-impermeable barrier 102 from the outer surface 105 to the inner surface 103, thereby allowing fluid to enter chamber 104 from the outside of the fluid collection device 100. The location and shape of opening 106 may be designed to be positioned adjacent to the female urethra when the device is in use. At least a portion of the porous material disposed in chamber 104 (e.g., protrusion 130) may be exposed through opening 106 to receive fluid and allow fluid to move inward (e.g., wicking) into chamber 104.

[0030] The fluid collection device 100 can be located close to the female urethra, and urine can enter the chamber 104 through the opening 106. In use, the opening 106 can be an elongated shape extending from a first location below the urethral opening (e.g., at or near the anus or vaginal opening) to a second location above the urethral opening (e.g., at or near the top of the vaginal opening or the pubic area).

[0031] Because the space between a woman's legs is relatively small when her legs are closed, the opening 106 can be elongated, allowing fluid to flow only along a path corresponding to the elongated shape of the opening 106 (e.g., a longitudinally extending opening). The opening 106 in the impermeable barrier 102 can have a length measured along the longitudinal axis of the fluid collection device 100, which can be at least about 10% of the length of the fluid collection device 100, for example, 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 95% of the length of the fluid collection device 100.

[0032] The opening 106 in the fluid-impermeable barrier 102 can have a width measured transverse to the longitudinal axis of the fluid collection device 100, which can be at least about 10% of the circumference of the fluid collection device 100, for example, 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. Since a vacuum (e.g., suction) through the conduit 108 draws fluid through the porous material 115 and into the conduit 108, the opening 106 can have a width greater than 50% of the circumference of the fluid collection device 100. The opening 106 can be vertically oriented (e.g., having a main axis parallel to the longitudinal axis of the device 100). In some embodiments (not shown), the opening 106 can be horizontally oriented (e.g., having a main axis perpendicular to the longitudinal axis of the device 100). In one embodiment, the fluid-impermeable barrier 102 can be attached to an individual, for example, adhered to an individual (e.g., with a hydrogel adhesive). According to one embodiment, a suitable adhesive is a hydrogel layer.

[0033] The fluid collection device 100 includes a porous material 115 disposed in a chamber 104. The porous material 115 may extend across at least a portion (e.g., all) of an opening 106. At least a portion of the porous material 115 may be exposed to the environment outside the chamber 104 through the opening 106. For example, at least a protrusion 130 may extend through the opening 106 and be exposed to the environment outside the chamber 104. The composition of the porous material 115 may be designed to wick away any fluid from the opening 106, thereby preventing fluid from escaping from the chamber 104. The porous or 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” of a porous material may not include the adsorption of fluid into the porous material. In other words, after the material has been exposed to fluid and the fluid has been removed for a period of time, substantially no fluid adsorption into the porous material occurs. While adsorption is undesirable, the term "substantially no adsorption" allows trace amounts of fluid to adsorb and / or dissolve into the porous material (e.g., adsorption rate), for example, less than about 30 wt% of the dry weight of the porous material, about 20%, about 10%, about 7 wt%, about 5 wt%, about 3 wt%, about 2 wt%, about 1 wt%, or about 0.5 wt% of the dry weight of the porous material. In some embodiments, the porous material may comprise at least one adsorbent or absorbent material. The porous material 115 may also allow fluid to move generally toward the interior of the chamber 104 or be wicked, as discussed in more detail below.

[0034] The porous material 115 includes a body 116 and a protrusion 130. The body 116 forms the main shape and structure of the porous material 115. For example, the body 116 may be substantially cylindrical (e.g., the protrusion 130 is ignored), while the protrusion 130 extends from the body 116. For example, the protrusion 130 may extend longitudinally along the body 116 (e.g., along and away from the longitudinal axis of the body 116). The body 116 may be substantially cylindrical, ellipsoidal, prismatic, etc. As discussed in more detail below, the size and shape of the protrusion 130 are designed to be installed between the labia (e.g., the labia majora of the wearer) and with its outermost portion placed adjacent to the wearer's urethra.

[0035] The porous material 115 may include one or more of the fluid-permeable membrane 118 and the fluid-permeable support 120. The fluid-permeable membrane 118 may include any fluid-permeable material, such as a porous material or a material capable of wicking fluid. For example, the fluid-permeable membrane 118 may include fabrics, such as gauze (e.g., silk, linen, or cotton gauze), other soft fabrics, or other smooth fabrics. The fluid-permeable membrane 118 may include spun plastic fibers (e.g., nylon), such as spun plastic mats or beds. The fluid-permeable membrane 118 formed from gauze, soft fabrics, and / or smooth fabrics can reduce chafing caused by the fluid collection device 100.

[0036] The fluid collection device 100 may include a fluid-permeable membrane 118 disposed in a chamber 104. The fluid-permeable membrane 118 may cover at least part (e.g., all) of the opening 106. The fluid-permeable membrane 118 may be configured to receive any fluid and allow any fluid to move inward away from the opening 106 (e.g., wicking), thereby preventing fluid from escaping from the chamber 104.

[0037] The fluid collection device 100 may include a fluid-permeable support 120 disposed in a chamber 104. The fluid-permeable support 120 is configured to support a fluid-permeable membrane 118, as the fluid-permeable membrane 118 may be formed of a foldable, thin, or deformable material. For example, the fluid-permeable support 120 may be positioned such that the fluid-permeable membrane 118 is disposed between the fluid-permeable support 120 and the fluid-impermeable barrier 102. Thus, the fluid-permeable support 120 can support and maintain the position of the fluid-permeable membrane 118. The fluid-permeable support 120 may include any material capable of wicking fluid, such as any fluid-permeable membrane material disclosed herein. For example, when a fluid-permeable membrane material is used as the fluid-permeable support 120, the fluid-permeable membrane material may be used in a denser or more rigid form than the fluid-permeable membrane 118. The fluid-permeable support 120 may be formed in a denser or more rigid form from any fluid-permeable material that is less deformable than the fluid-permeable membrane 118 (such as any material disclosed herein for the fluid-impermeable membrane 118). For example, the fluid-permeable support 120 may comprise a porous polymer (e.g., nylon, polyester, polyurethane, polyethylene, polypropylene, etc.) structure or an open-cell foam or spun plastic fibers (e.g., nylon fibers). In some embodiments, the fluid-permeable membrane 118 may comprise gauze, and the fluid-permeable support may comprise spun nylon fibers. In some embodiments, the fluid-permeable support 120 may be formed from natural materials such as cotton, wool, silk, or combinations thereof. In these embodiments, the material may have a coating (e.g., a waterproof coating) to prevent or limit fluid adsorption into the material. In some embodiments, the fluid-permeable support 120 may be formed from fabric, felt, gauze, or combinations thereof. In some embodiments, the fluid-permeable support 120 may be omitted from the fluid collection device 100. In some embodiments, the fluid-permeable membrane 118 may be optional. For example, the porous material 115 may comprise only the fluid-permeable support 120.

[0038] The fluid-permeable support 120 may have a greater wicking capacity or ability to allow fluid to flow through it than the fluid-permeable membrane 118, for example, to allow fluid to move inward from the outer surface of the fluid collection device 100. In some embodiments, the permeability of the fluid-permeable support 120 and the fluid-permeable membrane 118 may be substantially the same.

[0039] As shown in the figure, the main body 116 of the porous material 115 can form most of the structure of the porous material 115. The protrusion 130 can extend from or away from the main body 116. Therefore, the protrusion 130 can be installed in parts of the wearer's body where the main body 116 cannot be installed.

[0040] Figure 1BThe main body 116 can be substantially cylindrical, and the protrusion 130 can be pointed. In embodiments, the main body 116 can be an elliptical structure, a rectangular structure, a prismatic structure, or a flat tubular structure. The pointed protrusion 130 can extend a distance away from the main body 116. For example, the protrusion 130 can extend at least 3 mm away from the main body, such as 3 mm to 2.5 cm, 3 mm to 1 cm, 5 mm to 1.5 cm, 1 cm to 2 cm, at least 5 mm, less than 2.5 cm, less than 1.5 cm, or less than 1 cm. The bottom width of the protrusion 130 can be at least 5 mm, such as 5 mm to 2 cm, 5 mm to 1.5 cm, 1 cm to 2 cm, less than 2.5 cm, or less than 1.5 cm. The size of the protrusion 130 can vary, for example, based on the size and shape of the main body 116.

[0041] like Figures 1B to 1D As shown, the fluid-permeable support 120 may include a protrusion 130. For example, the fluid-permeable support 120 may form a protrusion 130, and the fluid-permeable membrane 118 may be adapted to it. The protrusion 130 may be a convex surface having a radius of curvature. The radius of curvature of the protrusion may be smaller than the radius of curvature of the body 116. As shown, the fluid-permeable membrane 118 may be disposed within the chamber 104 and extend across the opening 106. The fluid-permeable support 120 is also disposed within the chamber 104, below the fluid-permeable membrane 118, and includes the protrusion 130. The protrusion 130 may extend and project from the opening 106. Therefore, the protrusion 130 extends beyond the fluid-impermeable barrier 102. The fluid-permeable membrane 118 on the protrusion 130 may also extend beyond the fluid-impermeable barrier 102.

[0042] The protrusion 130 may extend along the entire longitudinal length of the porous material 115. For example, the protrusion 130 of the porous material 115 may extend along the entire longitudinal length of the body 116. In embodiments where the protrusion 130 extends along the entire length of the porous material 115 (e.g., the body), the end of the protrusion 130 may be tucked or folded under the fluid-impermeable barrier 102. In such embodiments, the end of the protrusion does not need to be removed for installation within the cavity.

[0043] In some embodiments, the protrusion 130 may extend less than the entire longitudinal length of the porous material 115 (e.g., body 116). For example, the protrusion 130 of the porous material 115 may extend along a first half, a second half, or a central portion of the longitudinal length of the body 116. In some embodiments, one or more lengths of the protrusion 130 may be removed from the porous material 115. For example, the ends of the protrusion 130 may be trimmed from the body 116 so that the protrusion 130 extends only along a portion of the porous material 115 located in the opening 106. In some embodiments, the protrusion may be provided only on a first longitudinal half of the porous material 115 extending through the opening 106 (e.g., closest to the first end region 125). In such embodiments, the protrusion 130 may be present only in an area near the urethra of a female wearer during intended use of the fluid collection device. By limiting the amount of the protrusion only to the first longitudinal half, the fluid collection device can be made as comfortable as possible for the wearer.

[0044] The fluid-permeable membrane 118 and the fluid-permeable support 120 can at least substantially completely fill the portion of chamber 104 not occupied by conduit 108. In another embodiment, the fluid-permeable membrane 118 and the fluid-permeable support 120 may not substantially completely fill the portion of chamber 104 not occupied by conduit 108. In such an embodiment, the fluid collection device 100 includes a reservoir within chamber 104. Figure 1D ).

[0045] The fluid collection device 100 may include a conduit 108 extending into the chamber 104. For example... Figure 1DAs shown, conduit 108 may be at least partially disposed within chamber 104. Conduit 108 (e.g., a tube) has an inlet 110 in a first end region and an outlet 112 in a second end region downstream of inlet 110. Conduit 108 may extend into chamber 104 to any point therein. For example, conduit 108 may be inserted into chamber 100 at a first end region 125 and extend through chamber 100 to a second end region 127 of fluid collection device 100. Conduit 108 may extend from first end region 125 (e.g., near outlet 112) into fluid-impermeable barrier 102 until second end region 127 (e.g., opposite first end region 125), to a point near reservoir 122, to allow inlet 110 to fluidly communicate with reservoir 122. In one embodiment (not shown), conduit 108 may enter chamber 104 through second end region 127, and inlet 110 of conduit 108 may be located in second end region 127 (e.g., in reservoir 122 or flush with fluid-permeable barrier 102). Fluid collected in reservoir 122 may be removed from chamber 104 through conduit 108. In some embodiments, inlet 110 may be located at the end of fluid-permeable support 120 in second end region 127, for example, flush with the end of fluid-permeable support 120. In some embodiments, inlet 110 may be located within fluid-permeable support 120, for example, between first end region 125 and second end region 127.

[0046] The catheter 108 may include a flexible material, such as a plastic tube (e.g., a medical tube). Such a plastic tube may include thermoplastic elastomer tubes, polyvinyl chloride tubes, ethylene vinyl acetate tubes, polytetrafluoroethylene tubes, etc. In some embodiments, the catheter 108 may include silicone or latex. In some embodiments, the catheter 108 may include one or more resilient portions, for example, by having one or more of a diameter or wall thickness that allows the catheter to be flexible. In some embodiments, the catheter 108 may be frosted or opaque (e.g., black) to obscure the visibility of the fluid therein.

[0047] The fluid collection device 100 can be operatively coupled to a vacuum source. For example, the conduit 108 connects the interior region of the chamber 104 to a fluid storage container. Figure 6 ) or vacuum source ( Figure 6 Fluid connection. Therefore, fluid can be removed from chamber 104 through conduit 108.

[0048] The fluid-impermeable barrier 102, the fluid-permeable membrane 118, and the fluid-permeable support 120 can be configured such that the conduit 108 is at least partially disposed within 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 for receiving the conduit 108. The fluid-impermeable barrier 102 can define an orifice sized to receive the conduit 108. At least one conduit 108 can be disposed within the chamber 104 through the orifice. The orifice can be configured to form a seal with the conduit 108 or at least one tube that is at least substantially fluid-impermeable, thereby substantially preventing fluid from escaping from the chamber 104. Fluid collected in the fluid collection device 100 can be removed from the chamber 104 through the conduit 108.

[0049] The porous material 115 (e.g., fluid-permeable membrane 118 and fluid-permeable support 120) may not substantially completely fill the portion of chamber 104 not occupied by conduit 108. The fluid collection device 100 may include a reservoir 122 located therein. As shown, the reservoir 122 is the substantially unoccupied portion of chamber 104. The reservoir 122 may be defined between a fluid-impermeable barrier 102 and the porous material 115 (e.g., one or both of fluid-permeable membrane 118 and fluid-permeable support 120). Fluid expelled by the wearer may be wicked into chamber 104 by the porous material 115 (initially through protrusion 130) and may flow through the fluid-permeable membrane 118 and / or fluid-permeable support 120 to the reservoir 122. The fluid-impermeable barrier 102 may retain fluid in the reservoir 122. The reservoir 122 may be located in the portion of the fluid collection device intended to be at the lowest point of gravity of the fluid collection device when worn by the user. Although reservoir 122 is depicted in the second end region 127, reservoir 122 can be located in any part of chamber 104, such as in the first end region 125.

[0050] In one embodiment, the fluid-impermeable barrier 102 may be breathable but impermeable to liquids. In such an embodiment, the fluid-impermeable barrier 102 may be formed of a hydrophobic material that defines a plurality of pores that are breathable but impermeable to liquids. In one embodiment, at least one or more portions of at least the outer surface of the fluid-impermeable barrier 102 may be formed of a soft and / or smooth material to reduce abrasion.

[0051] In some embodiments, the fluid collection device 100 may include a plurality of reservoirs, such as a first reservoir located in the portion of chamber 104 closest to inlet 110 (e.g., second end region 127) and a second reservoir located in the portion of chamber 104 closest to outlet 112 (e.g., first end region 125). In another embodiment, fluid may be spaced apart from at least a portion of conduit 108 by support 120, and reservoir 122 may be a space between support 120 and conduit 108 that is fluid-permeable.

[0052] The fluid-impermeable barrier 102, the fluid-permeable membrane 118, and the fluid-permeable support 120 can be configured to at least partially house the conduit 108 within 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 for receiving the conduit 108. In another embodiment, the fluid-impermeable barrier 102 can define an orifice 124 sized to receive the conduit 108 (e.g., at least one tube). At least one conduit 108 can be housed within the chamber 104 through the orifice 124. The orifice 124 can be configured to form a seal with the conduit 108 that is at least substantially impermeable to fluid, thereby substantially preventing fluid from escaping from the chamber 104. Fluid collected in the fluid collection device 100 can be removed from the interior region of the chamber 104 through the conduit 108. Figure 1D As shown, the end of the conduit 108 may extend beyond the fluid-permeable membrane 118 and / or the fluid-permeable support 120, for example, into the reservoir 122. In some embodiments, the inlet 110 may not extend into the reservoir 122. In such embodiments, the inlet 110 may be located within or at the end of the porous material 115 (fluid-permeable membrane 118 and / or fluid-permeable support 120). For example, the end of the conduit 108 may be co-extended with or embedded within the fluid-permeable membrane 118 and / or fluid-permeable support 120.

[0053] By placing the inlet 110 at or near the expected low point of gravity in chamber 104 when worn by the user, compared to placing the inlet 110 elsewhere, the conduit 108 can receive more fluid and reduce the likelihood of buildup (e.g., fluid buildup can lead to microbial growth and unpleasant odors). For example, fluid in the fluid-permeable membrane 118 and fluid-permeable support 120 can flow in any direction due to capillary forces. However, fluid may tend to flow in the direction of gravity, especially when the fluid saturates at least a portion of the fluid-permeable membrane 118 and / or fluid-permeable support 120. Therefore, one or more of the inlet 110 or reservoir 122 can be located in the second end region 127.

[0054] Other embodiments of fluid-impermeable barriers, fluid-permeable membranes, fluid-permeable supports, chambers, conduits, and their shapes and configurations are disclosed in U.S. Patent No. 10,973,678, filed June 2, 2017; U.S. Patent No. 10,390,989, filed September 8, 2016; and U.S. Patent No. 10,226,376, filed June 1, 2017, each of which is incorporated herein by reference in its entirety.

[0055] Although the protrusion 130 is shown as being formed in the fluid-permeable support 120 and having a pointed shape, one or more of the shape and material composition of the protrusion 130 may be consistent with... Figures 1A to 1D The differences described in the text. Figure 2 This is a cross-sectional view of a fluid collection device 200 according to at least some embodiments. The fluid collection device 200 includes a fluid-impermeable barrier 102, a fluid-permeable membrane 218, a fluid-permeable support 220, a conduit 108, and a protrusion 230. The fluid collection device 200 may be similar to or identical to the fluid collection device 100 in one or more respects. For example, one or more components or portions of the fluid collection device 200 may be similar to, or be identical to, a corresponding component or portion of the fluid collection device 100 in one or more respects in terms of size, shape, material composition, or component relationships. The fluid-permeable membrane 218 may be similar to or identical to the fluid-permeable membrane 118 in one or more respects. The fluid-permeable support 220 may be similar to or identical to the fluid-permeable support 120 in one or more respects.

[0056] As shown, the protrusion 230 can be formed from a fluid-permeable membrane 218. For example, the fluid-permeable membrane 218 may include shaped portions 231 (e.g., pointed) to form the protrusion 230. The protrusion 230 can be formed as part of a stitch, seam, or additional material in the fluid-permeable membrane 218. The protrusion 230 may be similar to or identical to the protrusion 130 in one or more aspects (e.g., size or location). In such embodiments, the protrusion 230 may be softer or more adaptable than a protrusion formed by a fluid-permeable support (e.g., protrusion 130). These embodiments may be more comfortable for the wearer than embodiments in which the protrusion is formed by a fluid-permeable support.

[0057] In some embodiments, the protrusion may not be shaped into a pointed tip. Figure 3This is a cross-sectional view of a fluid collection device 300 according to at least some embodiments. The fluid collection device 300 includes a fluid-impermeable barrier 102, a fluid-permeable membrane 318, a fluid-permeable support 320, a conduit 108, and a protrusion 330. As shown, the protrusion 330 includes a lobe. The fluid collection device 300 may be similar to or identical to fluid collection devices 100 or 200 in one or more respects. For example, one or more components or portions of the fluid collection device 300 may be similar to corresponding components or portions of fluid collection devices 100 or 200 in one or more respects in terms of size, shape, material composition, or component relationship. The fluid-permeable membrane 318 may be similar to or identical to fluid-permeable membrane 118 in one or more respects. The fluid-permeable support 320 may be similar to or identical to fluid-permeable support 120 in one or more respects.

[0058] As shown, the protrusion 330 can be formed as a blade 332, such as the blade of one or more of the fluid-permeable support 320 or the fluid-permeable membrane 318. For example, the body portion of the fluid-permeable support 320 may include a portion protruding from the body that is shaped as a blade 332 to form at least a portion of the protrusion 330. The blade 332 can be formed by pinching a portion of the fluid-permeable support 320 to form a neck between the blade and the body of the fluid-permeable support 320. This neck can be sewn to form the blade 332. Thus, the blade 332 protrudes from the body of the fluid-permeable support 320. In some embodiments, the blade 332 and the body of the fluid-permeable support 320 may be integrally formed, for example, by molding or extrusion. The protrusion 330 may be similar to or identical to the protrusions 130 or 230 in one or more aspects (e.g., size, location, material composition). The fluid-permeable membrane 318 is disposed over the body of the fluid-permeable support 320 and the blade 332. Therefore, the wearer-facing outer surface of the device 300 has a relatively smooth outer surface, without the discontinuity introduced by the neck between the blade 332 and the body of the fluid-permeable support 320. In some embodiments, the blade 332 may be a separate portion of the fluid-permeable support disposed on the body of the fluid-permeable support 320.

[0059] In some embodiments, the protrusion may be a separate portion of the fluid-permeable support that is bonded to the body of the fluid-permeable support. Figure 4This is a cross-sectional view of a fluid collection device according to at least some embodiments. The fluid collection device 400 includes a fluid-impermeable barrier 102, a fluid-permeable membrane 418, a fluid-permeable support 420, a conduit 108, and a protrusion 430. As shown, the protrusion 430 includes a separate portion 428 of fluid-permeable support material. The fluid collection device 400 may be similar to or identical to fluid collection devices 100, 200, or 300 in one or more respects. For example, one or more components or portions of the fluid collection device 400 may be similar to one or more of the size, shape, material composition, or component relationships of corresponding components or portions of fluid collection devices 100, 200, or 300 in one or more respects. The fluid-permeable membrane 418 may be similar to or identical to fluid-permeable membrane 118 in one or more respects. The fluid-permeable support 420 may be similar to or identical to fluid-permeable support 120 in one or more respects.

[0060] As shown, the protrusion 430 can be formed as a separate portion 428 of fluid-permeable support material separate from the body of the fluid-permeable support 420. The separate portion 428 can be made of the same fluid-permeable support material as the body of the fluid-permeable support 420 or a different fluid-permeable support material (e.g., a material with less wicking power or a softer feel than the body). For example, the separate portion 428 may include a portion of fluid-permeable support material separated from the material of the body. The separate portion 428 can be pointed, leaf-shaped, or similar in shape. The separate portion 428 can be bonded to the body of the fluid-permeable support 420 by adhesive or thermal welding. In some embodiments, the separate portion 428 can be disposed within a fluid-permeable membrane 418, and the fluid-permeable membrane 418 can be disposed on the fluid-permeable support 420. In such embodiments, the fluid-permeable membrane 418 can be disposed between the body of the fluid-permeable support 420 and the separate portion 428. The protrusion 430 may be similar to or the same as the protrusions 130, 230, and 330 in one or more aspects (e.g., size, location, material composition).

[0061] Figure 5 It is positioned on the wearer for use according to at least some implementation methods. Figure 1A A cross-sectional view of the fluid collection device along the plane AA is shown. As shown, the protruding portion 130 of the fluid collection device 100 is positioned between the labia 503 of the wearer 500. The height of the protruding portion 130 is chosen such that the outermost surface of the protruding portion is positioned adjacent to the urethra 505 of the wearer 500. Therefore, urine discharged by the wearer 500 immediately contacts the protruding portion 130 and is drawn towards the center of the device 100. The fluid collection device disclosed herein limits and prevents urine leakage due to poor contact between the fluid collection device and the wearer.

[0062] Furthermore, the protrusion 130 increases the surface area of ​​contact between the device 100 and the wearer 500, which helps to keep the device 100 in an ideal position during use. For example, the protrusion 130 rubs between the device 100 and the labia and mucous membrane in the urethral region of the wearer 500. During use, the device 100 may rub against the wearer's thigh 507. If the wearer 500 moves, the device 100 may be subjected to rotational or translational forces in one direction or the other due to contact with the thigh 507. The protrusion 130 also helps the device 100 resist rotation and translation by providing structural contact between the labia (e.g., the labia majora) and the device 100.

[0063] Any fluid collection device disclosed herein can be used in a fluid collection system. Figure 6 This is a block diagram of a system 600 for collecting fluid according to one embodiment. System 600 includes a fluid collection device 601, a fluid storage container 619, and a vacuum source 629. The fluid collection device 601, the fluid storage container 619, and the vacuum source 629 can be fluidly connected to each other via one or more conduits 108. For example, the fluid collection device 601 can be operatively connected via conduits 108 to one or more of the fluid storage container 619 and the (portable) vacuum source 629.

[0064] The fluid collection device 601 may be similar to or the same as any fluid collection device disclosed herein. For example, the fluid collection device 601 may include a fluid-impermeable barrier defining an opening and a porous material including protrusions projecting from the opening, as disclosed herein. The fluid collection device 601 may include a conduit 108 having an inlet and an outlet, as disclosed herein. The outlet may be fluidly connected to a fluid storage container 619, and the inlet may be located within the fluid collection device 601, for example, in a portion of a chamber therein (e.g., a reservoir), which is selected to be located at the lowest point of gravity of the fluid collection device 601 when worn by a user.

[0065] The conduit 108 is connected to one or more of the fluid storage container 619 and the vacuum source 629, and extends at least partially between them. In one embodiment, the conduit 108 is directly connected to the vacuum source 629. In such an embodiment, the conduit 108 may extend from the fluid collection device 601 by at least 1 foot, at least 3 feet, at least 5 feet, or at least 10 feet. In another embodiment, the conduit 108 may be indirectly connected to at least one of the fluid storage container 619 and the vacuum source 629. In some embodiments, the conduit may be secured to the wearer's skin by a conduit securing device, such as those provided by CRBard, Inc. Catheter fixation devices, including but not limited to those disclosed in U.S. Patent Nos. 6,117,163, 6,123,398 and 8,211,063, the entire disclosure of which is incorporated herein by reference.

[0066] Entrance (110, Figures 1A to 1C ) and exports (112, Figures 1A to 1C For example, a vacuum source 629 can be fluidly connected (e.g., directly or indirectly) to a chamber (104) or a reservoir 122 therein via one or more connectors thereon. Figures 1A to 1C In one embodiment, the inlet and / or outlet may form a male connector. In another embodiment, the inlet and / or outlet may form a female connector. In one embodiment, the inlet and / or outlet may include ribs configured to facilitate a robust coupling connection. In one embodiment, the inlet and / or outlet may be tapered. In one embodiment, the inlet and / or outlet may include a rigid or flexible material.

[0067] Fluid (e.g., urine or other bodily fluids) collected in fluid collection device 601 can be removed from fluid collection device 601 through conduit 108. For example, a first open end of conduit 108 in fluid collection device 601 is fluidly connected to a second open end of conduit 108, which may be located in fluid storage container 619 or vacuum source 629. In response to a suction (e.g., vacuum) force applied to the second end of conduit 108, this suction force can be introduced into the internal region of fluid collection device 601 through the first open end of conduit 108. The suction force can be applied directly or indirectly to the second open end of conduit 108 through vacuum source 629. When vacuum source 629 applies a vacuum / suction in conduit 108, fluid in the chamber of fluid collection device 601 (e.g., in the second end region, such as in reservoir 122) is drawn into the inlet and outlet of fluid collection device 601 through conduit 108.

[0068] Suction force can be applied indirectly through the fluid storage container 619. For example, a second open end (e.g., an outlet) of the conduit 108 can be disposed within the fluid storage container 619, and another conduit 108 can extend from the fluid storage container 619 to the vacuum source 629. Thus, the vacuum source 629 can indirectly apply suction to the fluid collection device 601 through the fluid storage container 619. In such an embodiment, the vacuum source 629 can provide a vacuum / suction to the fluid collection device through the fluid storage container to provide suction within the chamber of the fluid collection device. When fluid is discharged from the chamber of the fluid collection device 601, the fluid can flow through the first section of the conduit 108 to the fluid storage container 619, where it can then be retained.

[0069] In some embodiments, suction force can be applied directly through a vacuum source 629. For example, a second open end of the conduit 108 may be disposed within the vacuum source 629. Another conduit 108 may extend from the vacuum source 629 to an external point of the fluid collection device 601, such as extending to the fluid storage container 619. In such embodiments, the vacuum source 629 may be disposed between the fluid collection device 601 and the fluid storage container 619. In embodiments, the fluid storage container 619 may include a bag (e.g., a drainage bag), a bottle or cup (e.g., a collection can), a jar, or any other closed container for storing bodily fluids such as urine. In some embodiments, the fluid storage container 619 may be a rigid container.

[0070] Vacuum source 629 may include one or more of a manual vacuum pump, an electric vacuum pump, a diaphragm pump, a centrifugal pump, a positive displacement pump, a magnetically driven pump, a peristaltic pump, or any pump configured to generate a vacuum. In some embodiments, vacuum source 629 may be powered by one or more of a power cord (e.g., connected to a power outlet), one or more batteries, or even manual power (e.g., a manual vacuum pump). Vacuum source 629 disclosed herein may include one or more of a switch, a button, a plug, a remote control, or any other device suitable for activating vacuum source 629.

[0071] Figure 7 This is a flowchart of a method for collecting fluid according to one embodiment. The method 700 includes action 710, which describes "positioning a protruding portion of a fluid collection device adjacent to a female urethra, the fluid collection device comprising: a fluid-impermeable barrier having an outer surface and an inner surface, the inner surface at least partially defining a chamber, the fluid-impermeable barrier further defining an opening extending therethrough, the opening being configured to be positioned adjacent to the female urethra; a porous material having a body and a protruding portion extending longitudinally along the body and through the opening; and a conduit including an inlet and an outlet, the outlet being fluidly coupled to a fluid storage container, and the inlet being located within the chamber." Action 710 may be followed by action 720, which describes "receiving fluid from the female urethra into the fluid collection device." Action 720 may be followed by action 730, which describes "applying suction by a vacuum source fluidly coupled to the conduit to efficiently aspirate fluid from the chamber through the conduit."

[0072] Actions 710, 720, and 730 of method 700 are for illustrative purposes only. For example, actions 710, 720, and 730 of method 700 may be performed in a different order, divided into multiple actions, modified, supplemented, or combined. In one embodiment, one or more of actions 710, 720, and 730 of method 700 may be omitted from method 700. For example, action 730, which applies suction through a vacuum source fluidly connected to the conduit to effectively draw fluid from the chamber through the conduit, may be omitted. Method 700 may use any fluid collection device and / or fluid collection system disclosed herein. For example, any of actions 710, 720, or 730 may include the use of any fluid collection device or system disclosed herein.

[0073] Action 710 describes “positioning a protruding portion of a fluid collection device adjacent to a female urethra, the fluid collection device comprising: a fluid-impermeable barrier having an outer surface and an inner surface, the inner surface at least partially defining a chamber, the fluid-impermeable barrier further defining an opening extending therethrough, the opening being configured to be positioned adjacent to the female urethra; a porous material disposed within the chamber, the porous material having a body and a protruding portion extending longitudinally along the body and through the opening; and a catheter including an inlet and an outlet, the outlet being fluidly coupled to a fluid storage container, and the inlet being located within the chamber.” The fluid collection device or its components may be similar to or identical in one or more respects to any fluid collection device disclosed herein (e.g., 100-400).

[0074] Positioning the protruding portion of the fluid collection device adjacent to the female urethra can include positioning the opening on the female urethra, for example, positioning the longitudinally extending opening of the fluid collection device on the female urethra. Positioning the protruding portion of the fluid collection device adjacent to the female urethra can include positioning the protruding portion between the wearer's labia (e.g., the labia majora). Positioning the protruding portion of the fluid collection device adjacent to the female urethra can include longitudinally positioning the longitudinally extending protruding portion between the wearer's labia.

[0075] In some embodiments, action 710 may include positioning the protruding portion of the fluid collection device adjacent to the female urethra so that the protruding portion abuts against the female urethra. Positioning the protruding portion of the fluid collection device adjacent to the female urethra may include positioning the protruding portion within 2 cm of the female wearer's urethra, between the wearer's labia, for example, 0.1 mm to 2 cm, 0.1 mm to 5 mm, 5 mm to 1 cm, 1 cm to 2 cm, less than 1.5 cm, less than 1 cm, less than 5 mm, greater than 0.1 mm, or greater than 1 mm from the female wearer's urethra. Positioning the protruding portion of the fluid collection device adjacent to the female urethra may include positioning the fluid collection device between the wearer's thighs.

[0076] The action 720 of receiving fluid from the female urethra into a fluid collection device may include receiving the fluid into a porous material. The action 720 of receiving fluid from the female urethra into a fluid collection device may include moving (e.g., wicking) the fluid from the urethra through the porous material (e.g., through a fluid-permeable membrane and a fluid-permeable support). Receiving fluid from the female urethra into a fluid collection device may include wicking or otherwise moving the fluid through the porous material into the chamber of the fluid collection device (e.g., by gravity flow or suction). The action 720 of receiving fluid from the female urethra into a fluid collection device may include moving the fluid from a protrusion (e.g., wicking) into the body of the porous material (e.g., a fluid-permeable support). For example, the action 720 of receiving fluid from the female urethra into a fluid collection device may include using the protrusion, the fluid-permeable membrane, and the fluid-permeable support to wick or otherwise move the fluid away from the opening. In some embodiments, the action 720 may include causing the fluid to flow toward the chamber of the fluid collection device into a portion fluidly connected to the inlet of a conduit (which may be in fluid communication with a vacuum source). For example, action 720 may include directing fluid to a substantially unoccupied portion of the chamber (e.g., a reservoir), to a low point of gravity within the chamber, etc. In some embodiments, receiving fluid from the female urethra into the chamber of the fluid collection device may include wicking or otherwise moving the fluid (e.g., urine) into the chamber via a fluid-permeable membrane and fluid-permeable supports of the fluid collection device. For example, moving fluid into the chamber via a fluid-permeable membrane and fluid-permeable supports may include wicking or flowing (e.g., gravity flow or suction) urine into a reservoir within the fluid collection device.

[0077] Action 730, which applies suction via a vacuum source fluidly connected to a conduit to efficiently draw fluid from a chamber through the conduit, may include the use of any vacuum source disclosed herein. The vacuum source may be spaced apart from the fluid collection device, for example, by one or more portions of the conduit. In some embodiments, a fluid storage container is disposed between the vacuum source and the fluid collection device. Action 730 may include activating a vacuum source (e.g., a suction device) fluidly connected to the inlet of the conduit in the fluid collection device. In some embodiments, activating the vacuum source may include supplying power to the vacuum source by one or more of the following: flipping a switch, pressing a button, inserting the vacuum source into a power output port, inserting a battery into the vacuum source, etc. In some embodiments, the vacuum source may include a manually operated vacuum pump, and applying suction via the vacuum source may include manually operating the manually operated vacuum pump to efficiently draw fluid from the chamber through the conduit.

[0078] In some embodiments, applying suction with a vacuum source to effectively aspirate fluid from a chamber (e.g., an internal region) via a conduit disposed within the chamber and fluidly connected to the vacuum source can effectively remove at least some fluid (e.g., urine) from the chamber of the fluid collection device. In some embodiments, applying suction with a vacuum source to effectively aspirate fluid from a chamber via a conduit disposed within the chamber and fluidly connected to the vacuum source can effectively transfer at least some fluid from the chamber of the fluid collection device to a fluid storage container (e.g., a bottle or bag). In some embodiments, applying suction with a vacuum source to effectively aspirate fluid from a chamber can include removing fluid from one or more of a reservoir, a fluid-permeable support, and a fluid-permeable membrane of the fluid collection device.

[0079] In one embodiment, method 700 may include collecting fluid removed from a fluid collection device, for example, into a fluid storage container spaced apart from the fluid collection device and fluidly connected to a conduit. The fluid storage container may include any fluid storage container disclosed herein.

[0080] The fluid collection device, system, and method disclosed herein provide a secure positioning of the fluid collection device between the wearer's labia, very close to the female wearer's urethra, which prevents leakage and dislodgement of the fluid collection device.
