A person or animal may have limited or impaired mobility such that typical urination processes are challenging or impossible. For example, a person may experience or have a disability that impairs mobility. A person may have restricted travel conditions such as those experienced by pilots, drivers, and workers in hazardous areas. Additionally, sometimes urine collection is needed for monitoring purposes or clinical testing.
Urinary catheters, such as a Foley catheter, can be used to address some of these circumstances, such as incontinence. Unfortunately, urinary catheters can be uncomfortable, painful, and can lead to complications, such as infections. Additionally, bed pans, which are receptacles used for the toileting of bedridden patients are sometimes used. However, bedpans can be prone to discomfort, spills, and other hygiene issues.
In an embodiment, a fluid collection assembly is disclosed. The fluid collection assembly includes a reusable fluid impermeable barrier including a first end and a second end opposite the first end. The reusable fluid impermeable barrier includes at least one inner surface defining a chamber extending between the first end and the second end. The reusable fluid impermeable barrier also defines an outlet and at least one opening spaced from the outlet that both provide access to the chamber. The fluid collection assembly also includes at least one single use wicking cartridge configured to receive fluid. The reusable fluid impermeable barrier is configured to be transformed between a first configuration and a second configuration. The reusable fluid impermeable barrier does not allow the at least one single use wicking cartridge to be inserted and/or removed from the chamber when the reusable fluid impermeable barrier is in the first configuration and the reusable fluid impermeable barrier allows the at least one single use wicking cartridge to be inserted and/or removed from the chamber when the reusable fluid impermeable barrier is in the second configuration.
In an embodiment, a method of using a fluid collection assembly is disclosed. The method includes providing the fluid collection assembly including a reusable fluid impermeable barrier and a first single use wicking cartridge. The reusable fluid impermeable barrier includes a first end and a second end opposite the first end. The reusable fluid impermeable barrier including at least one inner surface defines a chamber extending between the first end and the second end. The reusable fluid impermeable barrier also defines an outlet and at least one opening spaced from the outlet that both provide access to the chamber. The reusable fluid impermeable barrier is configured to be transformed between a first configuration and a second configuration. The first single use wicking cartridge is configured to receive fluid. The method also includes, when the reusable fluid impermeable barrier is in the second configuration, inserting the first single use wicking cartridge in the chamber. The method further includes, after inserting the at least one single use first wicking cartridge in the chamber, transforming the reusable fluid impermeable barrier from the second configuration into the first configuration.
In an embodiment, a system is disclosed. The system includes a fluid collection assembly. The fluid collection assembly includes a first end and a second end opposite the first end. The reusable fluid impermeable barrier includes at least one inner surface defining a chamber extending between the first end and the second end. The reusable fluid impermeable barrier also defines an outlet and at least one opening spaced from the outlet that both provide access to the chamber. The fluid collection assembly also includes at least one single use wicking cartridge configured to receive fluid. The reusable fluid impermeable barrier is configured to be transformed between a first configuration and a second configuration. The reusable fluid impermeable barrier does not allow the at least one single use wicking cartridge to be inserted and/or removed from the chamber when the reusable fluid impermeable barrier is in the first configuration and the reusable fluid impermeable barrier allows the at least one single use wicking cartridge to be inserted and/or removed from the chamber when the reusable fluid impermeable barrier is in the second configuration. The system also includes a fluid storage container positioned downstream from the fluid collection assembly, a vacuum source positioned downstream from the fluid storage container, at least one first tube extending between and fluidly coupling the fluid collection assembly to the fluid storage container, and at least one second tube extending between and fluid coupling the fluid storage container to the vacuum source.
Features from any of the disclosed embodiments may be used in combination with one another, without limitation. In addition, other features and advantages of the present disclosure will become apparent to those of ordinary skill in the art through consideration of the following detailed description and the accompanying drawings.
The drawings illustrate several embodiments of the present disclosure, wherein identical reference numerals refer to identical or similar elements or features in different views or embodiments shown in the drawings.
Fluid collection assemblies, methods of using the same, and systems including the same are disclosed herein. An example fluid collection assembly includes a reusable fluid impermeable barrier that is configured to be reusable and at least one single use wicking cartridge that may not be configured to be reusable. The reusable fluid impermeable barrier defines an chamber therein. The reusable fluid impermeable barrier and the single use wicking cartridge are configured to have the single use wicking cartridge disposed in a chamber defined by the reusable fluid impermeable barrier. The fluid collection assembly may also include at least one tube that is at least partially disposed in the chamber or otherwise in fluid communication with the chamber. The tube is configured to remove other bodily fluids (e.g., urine) from the chamber. It is noted that the tube may also form part of a system that includes the fluid collection assembly.
The fluid collection assembly is configured to be transformed between a first state and a second state. When the fluid collection assembly is in the first state, the single use wicking cartridge is not disposed in (e.g., spaced from) the chamber of the reusable fluid impermeable barrier (
The fluid collection assembly is in the second state when the single use wicking cartridge is disposed in the chamber (
To transform the fluid collection assembly between the first and second states, the reusable fluid impermeable barrier may be transformable between a first configuration and a second configuration. When the reusable fluid impermeable barrier is in the first configuration, the reusable fluid impermeable barrier may prevent the single use wicking cartridge from being inserted into the chamber when the single use wicking cartridge is outside of the chamber and/or may prevent the single use wicking cartridge from being removed from the chamber when the single use wicking cartridge is inside of the chamber. When the reusable fluid impermeable barrier is in the second configuration, the single use wicking cartridge may be inserted and/or removed from the chamber.
In an embodiment, transforming the reusable fluid impermeable barrier between the first configuration and the second configuration includes changing the size of an opening of the reusable fluid impermeable barrier. For example, the opening of the reusable fluid impermeable barrier is closed or too small for the single use wicking cartridge to fit through when the reusable fluid impermeable barrier is in the first configuration while the opening of the reusable fluid impermeable barrier is sufficient large for the single use wicking cartridge to fit through when the reusable fluid impermeable barrier is in the second configuration. In an example, the reusable fluid impermeable barrier is transformed between the first configuration and the second configuration (e.g., the opening of the reusable fluid impermeable barrier changes size) by bending, stretching, or otherwise modifying the shape of the reusable fluid impermeable barrier.
Configuring the fluid collection assembly to be transformed between the first and second states allows the reusable fluid impermeable barrier to be reused, such as using the reusable fluid impermeable barrier with a plurality of single use wicking cartridges. For example, the reusable fluid impermeable barrier is often formed from silicone, other thermosetting polymer, other type of polymer, or combinations thereof. In such an example, the reusable fluid impermeable barrier may pose several environmental concerns related to its poor biodegradability and the scarce natural resources used to form the reusable fluid impermeable barrier. However, reusing the reusable fluid impermeable barrier decreases the environmental effect of using the reusable fluid impermeable barrier, such as by reducing the amount of waste generated when using the fluid collection assembly. It also decreases the cost of using the fluid collection assembly.
In an embodiment, the reusable fluid impermeable barrier may be reused only with the same individual. For example, the reusable fluid impermeable barrier may be used with the same individual and may receive one or more (e.g., a plurality of) single use wicking cartridges while being used with the individual. However, once the individual is done using the fluid collection assembly, the reusable fluid impermeable barrier is discarded. In an embodiment, the reusable fluid impermeable barrier may be used with multiple individuals. In such an embodiment, the reusable fluid impermeable barrier may be used with a first individual and may receive one or more (e.g., a plurality of) single use wicking cartridges while being used by the first individual. Once the first individual is done using the fluid collection assembly, the reusable fluid impermeable barrier is washed, such as with a disinfectant (e.g., at least one of antibacterial, antimicrobial, or antiseptic cleaner) and/or with an autoclave. Since the reusable fluid impermeable barrier is formed from silicone or other high temperature material, washing the reusable fluid impermeable barrier does not damage the reusable fluid impermeable barrier. The reusable fluid impermeable barrier may then be used with a second individual. It is noted that the reusable fluid impermeable barrier may be washed when the reusable fluid impermeable barrier is merely used with a single individual, such as when the reusable fluid impermeable barrier is used with the single individual for a long period of time and, for example, the growth of microbes in the reusable fluid impermeable becomes a concern.
The reusable fluid impermeable barrier 102 extends longitudinally between a first end 110 and an opposing second end 112. The reusable fluid impermeable barrier 102 defines at least one opening 114 positioned between the first and second ends 110, 112. The opening 114 is configured to be positioned adjacent to a female urethral opening and is configured to allow the female urethral opening to be in fluid communication with the chamber 104 when the opening 114 is positioned adjacent to the female urethral opening. For example, bodily fluids (e.g., urine) that are excreted by the female urethral opening enter the chamber 104 via the opening 114.
Generally, the opening 114 extends along a significant portion (e.g., at least 20%, at least 50%, at least 75%, 20% to 60%, 50% to 75%, or 60% to 90%) of a length of the reusable fluid impermeable barrier 102 to increase the amount of fluid that enters the chamber 104. In an example, the opening 114 includes an elongated opening. In an example, the opening 114 includes a plurality of slits.
In an embodiment, as previously discussed, the opening 114 may be configured to change sizes thereof, thereby allowing the reusable fluid impermeable barrier 102 to be transformed between the first and second configurations. For example, as illustrated in
The reusable fluid impermeable barrier 102 may be configured to bend or otherwise modify the shape thereof, thereby allowing the reusable fluid impermeable barrier 102 to be transformed between the first and second configurations. In an embodiment, at least a portion of the reusable fluid impermeable barrier 102 may be formed from a bendable and/or stretchable material, such as silicone or other suitable polymer thereby allowing the reusable fluid impermeable barrier 102 to bend and/or stretch. In an embodiment, the reusable fluid impermeable barrier 102 may include one or more hinges or other mechanical devices that allow the reusable fluid impermeable barrier 102 to bend or otherwise modify a shape thereof.
The reusable fluid impermeable barrier 102 may be configured to bend or otherwise modify the shape thereof in a specific location. In an embodiment, when the opening 114 is configured to change sizes, the specific location (i.e., the portion of the reusable fluid impermeable barrier 102 configured to bend or otherwise modify a shape thereof) is located closer to the first end 110 than the second end 112. Selecting the specific location to be closer to the first end 110 than the second end 112 may make it easier to maneuver the first end 110 around a first tip 121 of the single use wicking cartridge 106 when the single use wicking cartridge 106 is positioned in the chamber 104 and to position the single use wicking cartridge 106 around the tube 108. In an example, the specific location may be more bendable (e.g., flexible, stretchable, less rigid) than at least a portion of the reusable fluid impermeable barrier 102 that is between the specific location and the second end 112 which causes the reusable fluid impermeable barrier 102 to preferentially bend or otherwise modify a shape thereof at the specific location. For instance, the specific location may include a thinned region 120 (shown in
The reusable fluid impermeable barrier 102 also defines an outlet 116, for example, at the second end 112 thereof. The outlet 116 is configured to be coupled to and/or have the tube 108 disposed therein. As such, the outlet 116 allows the tube 108 to be in fluid communication with the chamber 104. In the illustrated embodiment, the tube 108 is also disposed in the chamber 104. In such an embodiment, the tube 108 may be positioned at or near a substantially empty fluid reservoir 118 (shown in
Referring to
In an embodiment, the single use wicking cartridge 106 may include permeable material designed to wick or pass fluid therethrough. The permeable properties referred to herein may be wicking, capillary action, diffusion, or other similar properties or processes, and are referred to herein as “permeable” and/or “wicking.” Such “wicking” may not include absorption of fluid into the wicking material. Put another way, substantially no absorption of fluid into the material may take place after the material is exposed to the fluid and removed from the fluid for a time. While no absorption is desired, the term “substantially no absorption” may allow for nominal amounts of absorption of fluid into the wicking material (e.g., absorbency), such as less than about 10 wt % of the dry weight of the wicking material, less than about 7 wt %, less than about 5 wt %, less than about 3 wt %, less than about 2 wt %, less than about 1 wt %, or less than about 0.5 wt % of the dry weight of the wicking material.
Wicking material can include natural fibers. In such examples, the material may have a coating to prevent or limit absorption of fluid into the material, such as a water repellent coating.
During use, the single use wicking cartridge 106 may receive bodily fluids from the individual during a time period, as will be discussed in more detail below. After use, the single use wicking cartridge 106 is removed from the fluid impermeable barrier 102 and disposed of. The single use wicking cartridge 106 may not be reused because the single use wicking cartridge 106 needs to be cleaned to be reused. Cleaning the single use wicking cartridge 106 includes removing all of the bodily fluids from and sterilizing all of the surfaces of the single use wicking cartridge. However, the porosity of the single use wicking cartridge makes removing all of the bodily fluids and sterilizing all of the surfaces of the single use wicking cartridge difficult and costly. Further, cleaning of the single use wicking cartridge may damage the single use wicking cartridge 106 and increase the volume of the single use wicking cartridge 106 due to the extreme cleaning measures required to remove all of the bodily fluids from and sterilize all of the surfaces of the single use wicking cartridge. The increased volume of the single use wicking cartridge 106 may prevent insertion of the single use wicking cartridge 106 into the chamber 104.
When the tube 108 is disposed in the chamber 104, the single use wicking cartridge 106 defines at least one passageway 126 extending at least partially therethrough. For example, the second tip 122 defines an entrance of the passageway 126 (not shown, obscured). The passageway 126 exhibits a size and shape that allows the passageway 126 to receive the tube 108 (e.g., the passageway 126 exhibits a size and shape that corresponds to or is slightly larger than the tube 108). The length of the passageway 126 depends on the length of the tube 108 that extends into the chamber 104. In particular, generally, the passageway 126 exhibits a length that is the same or greater than the length of a portion of the tube 108 that extends into the chamber 104. In an embodiment, the passageway 126 only extends partially through the single use wicking cartridge 106. In an embodiment, as illustrated, the passageway 126 extends completely through the single use wicking cartridge 106 such that the first tip 121 partially defines an opposing entrance of the passageway 126.
The outer surface 124 and the single use wicking cartridge 106, as a whole, may exhibit any suitable shape. For example, the outer surface 124 and the single use wicking cartridge 106 as a whole may exhibit a generally cylindrical shape (as shown), a generally box-like shape (e.g., an elongated generally box-like shape), a generally triangular prism-like shape (e.g., an elongated generally prism-like shape), a bent shape (e.g., a bent generally cylindrical shape), or any other suitable shape. However, the shape and size of the outer surface 124 and the single use wicking cartridge 106 may depend on the size and shape of the chamber 104. For example,
In an embodiment, the single use wicking cartridge 106 may exhibit a length that is less than the length of the chamber 104. In such an embodiment, the fluid collection assembly 100 may define at least one of a first gap 130 at and/or near the first end 110 of the reusable fluid impermeable barrier 102 or a second gap 132 at and/or near the second end 112 of the reusable fluid impermeable barrier 102. The first and/or second gaps 130, 132 may facilitate the operation of the fluid collection assembly 100. For example, the first gap 130 may form a substantially unoccupied gap at and/or near the first end 110 of the reusable fluid impermeable barrier 102. Since, in operation, the first end 110 tends to be the low point of the fluid collection assembly 100, fluid is likely to collect in the first gap 130 before being removed from the chamber 104 via the tube 108. As such, the first gap 130 forms part of the fluid reservoir 118. Further, the first gap 130 makes it easier to maneuver the first end 110 of the reusable fluid impermeable barrier 102 around the first tip 121 of the single use wicking cartridge 106 when transforming the reusable fluid impermeable barrier 102 between the first and second configurations thereof.
Further, as shown in

The fluid collection assembly 100 may be initially provided while the first single use wicking cartridge 106a is in an unused condition (e.g., the first single use wicking cartridge 106a has not receive any fluids). The fluid collection assembly 100 may then be positioned such that the opening 114 is adjacent to a urethral opening (e.g., the opening 114 of the illustrated fluid collection assembly 100 is configured to be adjacent to a female urethral opening), thereby allowing the first single use wicking cartridge 106a to receive bodily fluids from the urethral opening. Receiving bodily fluids from the urethral opening causes the first single use wicking cartridge 106a to be in a used condition. In an embodiment, the first single use wicking cartridge 106a may be removed from the chamber 104, for example, after the first single use wicking cartridge 106a is in the used condition or at some time after the first single use wicking cartridge 106a initially enters the used condition. In an embodiment, the first single use wicking cartridge 106a may be removed from the chamber 104 at some predetermined time after positioning the opening 114 adjacent to the urethral opening for sanitary reasons and/or to reduce clogging caused residual material deposited in the first single use wicking cartridge 106a by the fluids. The predetermined time may be at least about 1 hour, at least about 2 hours, at least about 4 hours, at least about 6 hours, at least about 8 hours, at least about 10 hours, at least about 12 hours, at least about 14 hours, at least about 16 hours, at least about 18 hours, at least about 20 hours, at least about 22 hours, at least about 24 hours, or in ranges of about 1 hour to about 4 hours, about 2 to about 6 hours, about 4 to about 8 hours, about 6 hours to about 10 hours, about 8 hours to about 12 hours, about 10 hours to about 14 hours, about 12 hours to about 16 hours, about 14 hours to about 18 hours, about 16 hours to about 20 hours, about 18 hours to about 22 hours, or about 20 hours to about 24 hours.

Once the second single use wicking cartridge 106b is correctly positioned into the chamber 104, the reusable fluid impermeable barrier 102 is transformed from the second configuration into the first configuration. For example, in the illustrated embodiment, the reusable fluid impermeable barrier 102 is transformed from the first configuration into the second configuration by bending the reusable fluid impermeable barrier 102 and maneuvering the first end 110 of the reusable fluid impermeable barrier 102 around the first tip 121b of the second single use wicking cartridge 106b, as shown in

The single use wicking cartridge 306b may also include an adhesive layer 338 between at least a portion of the fluid permeable support 334 and a corresponding portion of the fluid permeable membrane 336. The adhesive layer 338 maintains the positions of the fluid permeable support 334 and the fluid permeable membrane 336 relative to each other when the single use wicking cartridge 306b is inserted and/or removed from a chamber. For example, without the adhesive layer 338, the fluid permeable support 334 and the fluid permeable membrane 336 may be susceptible to move relative to each other which may make insertion and/or removal of the single use wicking cartridge 306b more difficult. Further, allowing the fluid permeable support 334 and the fluid permeable membrane 336 to move relative to each other may form non-desirous air gaps which may allow the fluid to pool and stagnate.
The single use wicking cartridge 306b may be formed using any suitable method. In an example, the single use wicking cartridge 306b may be formed using a dual extrusion process. In an example, the single use wicking cartridge 306b may be formed by rolling or extruding the fluid permeable support 334, and then positioning the fluid permeable membrane 336 around the fluid permeable support 334. The method of forming the single use wicking cartridge 306 may also include applying an adhesive to at least a portion of the exterior surface of the fluid permeable support 334 and positioning the fluid permeable membrane 336 around the fluid permeable support 334 also includes positioning the fluid permeable membrane 336 around the adhesive layer 338.

In an embodiment, the porous portion of the single use wicking cartridge 306c is integrally formed with at least one other component of the single use wicking cartridge 306c. However, the porous portion that is integrally formed with at least one other component of the single use wicking cartridge 306c may be difficult to form depending on the method used to form the single use wicking cartridge 306c. For example, the porous portion that is integrally formed with at least one other component of the single use wicking cartridge 306c may be difficult to form when the single use wicking cartridge 306c is formed by extrusion. As such, in an embodiment, the single use wicking cartridge 306c may include a plug 340 (e.g., the porous portion is the plug 340) that is distinct from the rest of the single use wicking cartridge 306c. The plug 340 may be positioned such that the plug 340 extends between the passageway 326c and the first tip 321 and the plug 340 wicks material from the first tip 321 to the passageway 326c. The plug 340 may exhibit a size that allows the plug 340 to be inserted into the passageway 326c. The plug 340 may be formed from the same or different material than the rest of the single use wicking cartridge 306c. In an example, the plug 340 may be adhesively attached to the rest of the single use wicking cartridge 306c.

In some embodiments, correct positioning of the single use wicking cartridge in the reusable fluid impermeable barrier may be important. In an example, inserting the single use wicking cartridge too far into the reusable fluid impermeable barrier may at least one of form an inefficiently large first gap that causes excessive pooling and stagnation of the fluids or may compress the portions of the single use wicking cartridge near the second end of the reusable fluid impermeable barrier which may make removal of the single use wicking cartridge difficult. In an example, failing the completely insert the singe use wicking cartridge into the reusable fluid impermeable barrier may at least one of prevent the formation of the fluid reservoir, make transforming the reusable fluid impermeable barrier between the first and second configurations difficult, or cause the formation of an inefficiently large second gap that causes excessive pooling and stagnation of the fluids. As such, the single use wicking cartridges disclosed herein may include one or more features that facilitate correct placement of the single use wicking cartridges.
In an embodiment, the features that facilitate the correct placement of the single use wicking cartridges in the reusable fluid impermeable barrier includes one or more markings formed on at least one of the reusable fluid impermeable barrier or the single use wicking cartridge. The markings on one of the reusable fluid impermeable barrier or the single use wicking cartridge may correspond to features (e.g., other markings) on the other of the reusable fluid impermeable barrier or the single use wicking cartridge.

To facilitate correct positioning the single use wicking cartridge 406b, the first marking 442b may be located adjacent to opening 414b of the reusable fluid impermeable barrier 402b. The first marking 442b may also be located nearer the second end 412b than the first end 410b of the reusable fluid impermeable barrier 402b such that bending or otherwise modifying the shape of the reusable fluid impermeable barrier 402b is unlikely to change the location of the first marking 442b.
In an embodiment, as illustrated, the second marking 444 extends around a circumference of the singe use wicking cartridge 406b. This allows the single use wicking cartridge 406b to be correctly positioned regardless of the rotation of the single use wicking cartridge 406b. However, it is noted that the second marking 444 may not extend around the circumference of the single use wicking cartridge 406b, for example, when the single use wicking cartridge 406b cannot be freely rotated relative to the reusable fluid impermeable barrier 402b.
Improper placement of the single use wicking cartridge in the chamber may cause the single use wicking cartridge to block or otherwise obscure an inlet of a tube. In an example, inserting the single use wicking cartridge too far into the chamber may cause a porous portion (e.g., plug 340 shown in

The features and principles regarding the fluid collection assemblies disclosed above may also be applied to a fluid collection assembly that is configured to receive urine from a male urethral opening (e.g., penis). For example,
The reusable fluid impermeable barrier 602 includes a first end 610 and an opposing second end 612. The first end 610 of the reusable fluid impermeable barrier 602 defines an opening 614 and the second end 612 of the reusable fluid impermeable barrier 602 may define the outlet 616 that is in fluid communication with the tube 608 (e.g., the tube 608 is positioned through the outlet 616). The opening 614 and the outlet 616 provide access to the chamber 604. As illustrated, the opening 614 is configured to receive the male urethral opening such that the male urethral opening is disposed in the chamber 604. However, it is noted that, in some embodiments, the opening 614 may be configured to be positioned adjacent to the male urethral opening (e.g., buried penis) instead of receiving the male urethral opening.
The reusable fluid impermeable barrier 602 is configured to be transformed between a first configuration and a second configuration. In the illustrated embodiment, the reusable fluid impermeable barrier 602 may include at least one flap 654 at the first end 610 thereof. The flap 654 may be configured to adjust the size of the opening 614. For example, the flap 654 may be configured to curve inwardly when the reusable fluid impermeable barrier 602 is in the first configuration thereby reducing the size of the opening 614 and preventing the single use wicking cartridge 606 from being inserted and/or removed from the chamber 604, as illustrated. However, the flap 654 may be flexible and/or stretchable such that the flap 654 may be configured to curve outwardly with some manipulation when the reusable fluid impermeable barrier 602 is in the second configuration thereby increasing the size of the opening 614 such that the single use wicking cartridge 606 may be inserted and/or removed from the chamber 604. It is noted that other mechanisms may be used instead of the flap 654. For example, the reusable fluid impermeable barrier 602 may include a cap or pin that can be used to be transformed the reusable fluid impermeable barrier 602 between the first and second configurations.
The single use wicking cartridge 606 may be substantially similar to any of the single use wicking cartridges disclosed herein. In an example, the single use wicking cartridge 606 is configured to wick fluids towards a fluid reservoir 618 that is located at or near the second end 612 of the reusable fluid impermeable barrier 602. In an example, as illustrated, the single use wicking cartridge 606 may include a single material, similar to the single use wicking cartridge 306a of
