It includes various specific details to assist in that understanding but these are to be regarded as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

[0017] The terms and words used in the following description and claims are not limited to the bibliographical meanings but are merely used by the inventor to enable a clear and consistent understanding of the invention. Accordingly, it should be apparent to those skilled in the art that the following description of exemplary embodiments of the disclosed invention are provided for illustration purpose only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.

[0018] By the term “substantially” it is meant that the recited characteristic, parameter, or value need not be achieved exactly, but that deviations or variations, including for example, tolerances, measurement error, measurement accuracy limitations and other factors known to those of skill in the art, may occur in amounts that do not preclude the effect the characteristic was intended to provide.

[0019] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. Thus, for example, reference to “a component surface” includes reference to one or more of such surfaces.

[0020] As used herein any reference to “one embodiment” or “an embodiment” means that a particular element, feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. The appearances of the phrase “in one embodiment” in various places in the specification are not necessarily all referring to the same embodiment.

[0021] As used herein, the terms “comprises,” “comprising,” “includes,” “including,” “has,” “having” or any other variation thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, article, or apparatus that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Further, unless expressly stated to the contrary, “or” refers to an inclusive or and not to an exclusive or. For example, a condition A or B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).

[0022] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the specification and relevant art and should not be interpreted in an idealized or overly formal sense unless expressly so defined herein. Well-known functions or constructions may not be described in detail for brevity and/or clarity.

[0023] It will be also understood that when an element is referred to as being “on,” “attached” to, “connected” to, “coupled” with, “contacting”, “mounted,” etc., another element, it can be directly on, attached to, connected to, coupled with, or contacting the other element or intervening elements may also be present. In contrast, when an element is referred to as being, for example, “directly on,” “directly attached” to, “directly connected” to, “directly coupled” with, or “directly contacting” another element, there are no intervening elements present. It will also be appreciated by those of skill in the art that references to a structure or feature that is disposed “adjacent” another feature may have portions that overlap or underlie the adjacent feature.

[0024] Spatially relative terms, such as “under,” “below,” “lower,” “over,” “upper,” and the like may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of a device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is inverted, elements described as “under” or “beneath” other elements or features would then be oriented “over” the other elements or features. Thus, the exemplary term “under” can encompass both an orientation of “over” and “under”. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. Similarly, the terms “upwardly,” “downwardly,” “vertical,” “horizontal,” and the like are used herein for the purpose of explanation only unless specifically indicated otherwise.

Ostomy Bag and Absorbent Insert

[0025] With reference to FIG. 1, the disclosed invention includes a urostomy system 100 comprising an ostomy bag 110 and absorbent insert 120. The ostomy bag 110 comprises a storage bag 112 having a perimeter 114, a front, and a back. The disclosed ostomy bag 110 is less than 12 inches in length from top to bottom, and preferably is 6 to 7 inches in length and 6 to 7 inches wide. The storage bag 112 is made of water-impermeable and odor-resistant polymer, and in preferred embodiments is translucent. The storage bag may be made from a polyvinyl chloride film. The storage bag 112 has a primary aperture 130 located near a top of the bag 112 and extending through the back to an inside, and a secondary aperture 140 located at or near a bottom of the bag 112 and extending through the perimeter 114 to the inside. The storage bag is permanently sealed along the perimeter 114, with the exception of the secondary aperture 140, which can be selectively sealed or unsealed by means of a closure 142. The primary aperture 130 includes a sealing ring 132 that is configured to interact mechanically with a wafer (not shown) to form a watertight seal. The sealing ring is made of a polymer, plastic, nylon, rubber, or other material. The primary aperture 130 and sealing ring 132 are sized to fit around an ostomy opening in the wearer's abdomen. The ostomy opening includes a stoma, which projects out from the wearer's abdomen. The wafer is configured to fit around the stoma and is removably attached to the wearer's skin by an adhesive to form a watertight seal. The sealing ring 132 includes a plurality of tabs 134 (three are shown) that are configured to mechanically interact with corresponding slots on the wafer to removably secure the sealing ring to the wafer, and hence the ostomy bag 110 to the wearer. The sealing ring and wafer thus create a sealed pathway for waste from the wearer's body to the inside of the storage bag.

[0026] The secondary aperture 140 is sealed and unsealed by means of a closure 142 that is mechanically attached to the storage bag 112 around the secondary opening. The closure 142 may be a zipper-type closure having a slider 144 configured to close and open the secondary aperture 140 by moving the slider alternately to a closed or to an open position. Other types of resealable closure systems are possible and contemplated, such as a hook and loop closure, a tongue and groove closure, a snap closure, or other suitable configuration. In some embodiments, the secondary aperture is located along the bottom of the storage bag (not shown). In other embodiments, the secondary aperture is located along a side of the storage bag 112. In such side-opening embodiments, the secondary aperture 140 begins just above the bottom of the storage bag 112 to create a reservoir 116 for liquid waste to collect in the sealed area below the secondary aperture.

[0027] With reference to FIG. 2, a front view of the urostomy bag assembly 100 is shown with a lower front portion of the storage bag 112 cut away along the line 14 to allow a view of the absorbent insert 120. The absorbent insert itself is shown with a cutaway along the line 16, to allow a view of the insert's interior. The absorbent insert 120 includes, and is covered by, a water-permeable outer layer 122. The outer layer may be a nonwoven fabric made of wood fiber, polypropene, polyethylene, polyester, viscose, or other suitable material. In some embodiments, the outer layer 122 includes a deodorizer 128 coupled within its material. The deodorizer may be for example, sodium bicarbonate, diethylene glycol, activated charcoal, silica gel, or other material. The absorbent insert also includes one or more core(s) 124 that includes a gelatinizing agent 126. The one or more cores functions to provide structure to the gelatinizing agent or to contain the agent, and may be made of cellulose, nonwoven fabric, viscose, or other material. The gelatinizing agent may be a super absorbent polymer, sodium polyacrylate, potassium acrylate, alkyl acrylate, tragacanth, pectin, starch, carbomer, carrageenan, sodium alginate, gelatin, or others. The core 124 is contained within the outer layer 122, and is configured to absorb urine, capture it, and render it gelatinous. The absorbent insert 120 is insertable into, and removable from the inside of the storage bag 112 through the secondary aperture 140.

[0028] With reference to FIG. 3, a side view of the disclosed ostomy bag assembly 100 is shown. The primary aperture 130 is shown extending through the back of the storage bag 112 to the inside of the bag. The sealing ring 132 is mechanically attached to the storage bag material around the primary aperture 130 to form a watertight seal with the storage bag 112. The sealing ring may be attached to the storage bag by use of an adhesive, ultrasonic welding, melting, or other suitable technique. In some embodiments, the sealing ring 132 includes a lip 134 that has a larger diameter than the primary aperture to facilitate a secure, fluid-tight attachment between the sealing ring and the storage bag around the primary aperture.

[0029] FIG. 4 shows a perspective view of the disclosed ostomy bag 110 with the absorbent insert 120 removed. The secondary aperture 140 is shown open or unsealed, with the slider 144 of the closure 142 shown in the open position. The absorbent insert 120 is depicted with the outer layer 122 cutaway along the line 16 to allow a view of the core 124 that includes the gelatinizing agent 126. In some embodiments, one or more handles 123 (two are shown) are attached to the outer layer 122 to aid insertion and removal of the absorbent insert.

[0030] The ostomy bag 110 is prepared for use by opening the secondary aperture 140 and placing an unused absorbent insert 120 inside the storage bag 112, and closing or resealing the secondary aperture. The ostomy system 100 is then removably attached to a wearer by placing the primary aperture 130 over the wearer's ostomy opening, aligning the sealing ring 132 with the wafer, and snapping the sealing ring 132 into place on the wafer. When the wearer urinates, urine enters the storage bag 112 through the primary aperture where it contacts the absorbent insert 120. The gelatinizing agent 126 turns the urine into a gelatinous consistency and reduces contact between the urine and the primary and secondary apertures to prevent leakage. In some embodiments, the deodorizer 128 acts to neutralize or absorb odors and prevent them from leaving the storage bag 112. The ostomy bag 110 may be used for an extended period, e.g., 1-2 hours, 2-3 hours, 3-4 hours, 4-5 hours, or 5-6 hours, without being removed from the wearer's body. When necessary or desirable, a used absorbent insert 120 may be removed through the secondary aperture 140 and replaced with an unused absorbent insert.

[0031] With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.

[0032] As will be understood by those familiar with the art, the disclosed invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. Likewise, the particular naming and division of the modules, managers, functions, systems, layers, features, attributes, methodologies, and other aspects are not mandatory or significant, and the mechanisms that implement the invention or its features may have different names, divisions, and/or formats.

[0033] Accordingly, the disclosure of the disclosed invention is intended to be illustrative, but not limiting, of the scope of the invention.

[0034] This has been a description of the disclosed invention along with a preferred method of practicing the invention, however the scope of the inventions ought to be determined by the appended claims.
