Description

Technical Field

[0001] The present invention relates to an ostomy appliance, an excrement storage appliance, etc. that are used for storing excrement, excretory fluid, gas, exudate, secretion, etc. (hereinafter, these are collectively referred to as "excrement") from inside or on the surface of a living body.

Background Art

[0002] When defecation or urination cannot be controlled by one's own will, or when there is a disease in the digestive or urinary organs, a surgical operation may be performed to guide the intestinal or urinary tract to the body surface and create an opening on the body surface. This opening is also called a stoma. A person with a stoma needs to wear an ostomy appliance having a bag body or the like that can temporarily store excrement from the stoma. Also, in the case of a person with a urinary stoma, a leg bag may be used to increase the urine storage volume. In addition, a person with an opening or wound on the body surface due to other diseases also needs to wear a drainage management storage bag such as a drainage pouch around the opening or wound in order to process the excrement discharged by drainage or the like.

[0003] Excrement is stored in the bag body attached to the stoma. Since this bag body is made of a transparent or translucent film, the excrement in the process of being stored in the bag body and the stored excrement can be seen. For this reason, there are accessories such as a pouch cover that covers the bag body so that the excrement cannot be seen.

[0004] In addition, in order to prevent the excrement in the pouch film from being directly visible, those provided with a fiber sheet such as a woven fabric or a non-woven fabric on the surface of the transparent or translucent pouch film have been widely proposed.

[0005] For example, Patent Document 1 discloses a laminate material suitable for use in forming skin-contact products, which is used for the side walls of a body-worn pouch for collecting human excrement, and this laminate material comprises three independent layers: a fiber layer, a film layer, and an adhesive layer between them. The adhesive layer is disclosed to bond the fiber layer to the film layer substantially continuously.

[0006] Furthermore, for example, Patent Document 2 discloses that a stoma pouch includes a sheet of woven comfort material, and that the sheet of woven comfort material has an outer surface and an inner surface on the opposite side, and that the outer surface of the sheet of woven comfort material forms at least a portion of the outer surface of the pouch, and at least a portion of the inner surface of the sheet of woven comfort material is coated with a web of hot melt adhesive. [Prior art documents] [Patent Documents]

[0007] [Patent Document 1] Special Publication No. 2008-501554 [Patent Document 2] Special Publication No. 2023-534600 [Overview of the Initiative] [Problems that the invention aims to solve]

[0008] Patent Document 1 discloses that the laminate material includes a hot-melt thermoplastic adhesive having substantially the same extent on opposing surfaces of the fiber layer and the film layer, so as to adhere the fiber layer to the film layer substantially continuously. The technology in Patent Document 1 aims to reduce noise in the film layer by including a fiber layer. However, the present inventors have confirmed that because the entire surface of the laminate material is a film layer, a rustling and rubbing sound caused by body movements due to this film layer still occurs. Furthermore, in the technology in Patent Document 1, since the entire surface of the film layer is used as an adhesive to the entire surface of the fiber layer, material costs for the film layer are incurred, making it difficult to reduce manufacturing costs.

[0009] Patent Document 2 discloses a stoma pouch comprising a sheet of woven comfort material in which at least the space between the fiber layer and the film layer is coated with a web-like hot-melt adhesive. However, with the technology described in Patent Document 2, it is difficult to reduce manufacturing costs due to the material costs incurred for using the web-like hot-melt adhesive.

[0010] Furthermore, using a heat-sealed laminate material consisting of a fiber layer and a film layer, as shown in Patent Documents 1 and 2, or a sheet of a woven comfort material in which a web-like hot-melt adhesive is coated between the fiber layer and the film layer, can reduce discomfort during wear by making the excrement in the bag invisible to others. However, users also need to be able to check the condition of the excrement in the bag (such as its properties, quantity, and color) and the condition of the stoma. The inability to check these conditions makes it difficult to manage when to change the bag and when to dispose of the excrement, which can also cause discomfort for the user.

[0011] Furthermore, the inventors believe that even when the film of the bag is equipped with a surface fiber sheet portion having a structure that allows for internal inspection using a fiber sheet portion on at least one surface, the bonding strength between the film and the surface fiber sheet portion having said structure is good, so that users or medical professionals who provide the bag equipped with this surface fiber sheet portion can use or provide it with confidence.

[0012] Therefore, the main objective of the present invention is to provide an ostomy appliance that includes a surface fiber sheet portion having a structure that allows for internal inspection using a fiber sheet portion on at least one surface of the bag body, has good bonding strength between the bag body and the surface fiber sheet portion having said structure, can reduce manufacturing costs, and reduces discomfort during wear.

[0013] In this specification, "user" may mean an ostomate, or another person who assists an ostomate with regard to the use of the bag, for example (e.g., a healthcare worker, caregiver, etc.). In this specification, "ostomate" may refer to a person who has a stoma. Furthermore, "ostomate" may refer to a person who wears and is able to use an ostomy appliance. In this specification, the "skin-contacting side" refers to the side of a two-faced bag that is in contact with or close to the body surface, and the "non-skin-contacting side" refers to the side of a two-faced bag that is far from the body surface.

[0014] Furthermore, in this specification, "internal" in "internal inspection" means at least all or part of the bag body covered by the surface fiber sheet portion provided in the ostomy appliance, and may also include the faceplate and stoma located further inside. Also, "internal inspection" means inspecting the surface and / or inside of the bag body, and examples include the condition of the bag body (condition of the bag body surface, film, expansion ratio, deodorizing filter, etc.), the condition of the excrement contained in the bag body (understanding of properties, quantity, color, etc.), and what is visible through the bag body (for example, the condition of the stoma and its surroundings). [Means for solving the problem]

[0015] As a result of diligently investigating the above problems, the inventors have completed the following invention.

[0016] The present invention relates to an ostomy appliance comprising a surface fiber sheet portion on at least one surface of a bag-like body. The bag body and the surface fiber sheet portion are welded to each other at the outer edge of the bag body. The aforementioned surface fiber sheet portion, It comprises a first fiber sheet section and a second fiber sheet section, An overlapping portion formed from a portion of the overlap between the first fiber sheet portion and the second fiber sheet portion, which can be opened and closed for checking the surface and / or the inside of the bag, At both ends of the overlapping portion, there is a partial welding portion where the first fiber sheet portion and the second fiber sheet portion are partially welded to each other. An ostomy appliance can be provided.

[0017] The cross-sectional state of the partial welding portion is preferably not a completely film-formed state, but a state where there is a welded state between the film and the fiber. The partial welding portion preferably does not further contain a hot melt adhesive. The partial welding portion is preferably provided at the outer peripheral edge of the surface fiber sheet portion. The first fiber sheet portion and / or the second fiber sheet portion preferably further includes a melted edge portion where one or more edges existing other than the outer peripheral edge welded to the outer peripheral edge of the bag body are melted. The first fiber sheet portion and / or the second fiber sheet portion preferably does not further contain a hot melt adhesive at the melted edge portion. It is preferable to provide the melted edge portion at the overlapping portion in the first fiber sheet portion and / or the second fiber sheet portion. The bag body further includes a discharge port portion. The second fiber sheet portion preferably further includes a discharge port accommodating portion where the edge of the portion accommodating the discharge port portion is melted. It is preferable to further include a surface fiber sheet portion provided with a stoma opening portion whose edge is melted on the surface of the bag body opposite to the surface fiber sheet portion.

[0026] 1. Background and Overview of the Invention

[0027] The present inventors' primary objective is to provide an ostomy appliance that includes a surface fiber sheet portion on at least one surface of a bag body, which has a structure that allows for internal inspection using a fiber sheet portion, and that has good bonding strength between the bag body and the surface fiber sheet portion having said structure, while also reducing manufacturing costs and discomfort during wear.

[0028] Discomfort during use can include, for example, the fact that if the bag is transparent, others may be able to see the surface of the bag, its contents, and the inside of the stoma. To reduce this discomfort, the bag can be made opaque. However, using an opaque bag can have disadvantages, such as the inability to observe the surface of the bag (e.g., the surface of the film that makes it up) and / or the inside (e.g., the amount and color of the contents, the condition of the stoma, etc.), and the inability to understand and manage the user's health condition based on these observations. On the other hand, using an opaque or colored cover bag or detachable decorative parts can reduce the discomfort of being seen by others and allow for checks of the surface and inside of the bag as needed. However, this can lead to other discomforts during use, such as the inconvenience of attaching and detaching the cover bag or decorative parts, and the staining and odor caused by the contents adhering to the cover bag when the contents are emptied.

[0029] This discomfort can manifest, for example, when a fiber sheet (woven, knitted, nonwoven, etc.) is welded to the entire surface of one side of the bag via film or hot-melt adhesive. In such cases, the interposed film or hot-melt adhesive can cause a rustling sound during movement, or create bulkiness and stiffness, resulting in an uncomfortable feeling when wearing the bag.

[0030] Furthermore, bonding the bag and fiber sheet via hot-melt adhesive often results in greater comfort than bonding via film. However, in either case, the manufacturing cost increases due to the intervening film or hot-melt adhesive. Therefore, developing alternative technologies that do not use film or hot-melt adhesive to avoid this increased manufacturing cost presents technical challenges.

[0031] Furthermore, when fiber sheets are used in ostomy appliances, the edges of the fiber sheet are prone to fraying.

[0032] Minimizing such discomfort during wear is desirable for users of ostomy appliances and others who use them, as it allows them to lead more comfortable lives. At the same time, it is desirable to reduce materials and processes, thereby lowering manufacturing costs.

[0033] For example, the objective could be to provide an ostomy appliance that includes a surface fiber sheet portion on at least one surface of the bag body, which has a structure that allows for internal inspection using a fiber sheet portion, and that has good bonding strength between the bag body and the surface fiber sheet portion having said structure, while also reducing manufacturing costs and discomfort during wear.

[0034] Furthermore, the objective may also be to provide an ostomy appliance or excrement container that uses a fiber sheet portion on at least one surface of the bag film, thereby improving the durability of the ostomy appliance or excrement container and reducing manufacturing costs. Furthermore, another objective may be to provide an ostomy appliance or excrement container that has good durability at the joint between the surface fiber sheet and the bag body, and that can reduce manufacturing costs. Furthermore, the objective may also be to provide an ostomy appliance or a waste collection appliance in which fraying that occurs at the edges of the fibrous sheet portion used in the ostomy appliance or waste collection appliance is improved.

[0035] This technology includes the first technology, the second technology, and any appropriate combination of the components contained therein, as described below. This technology will enable the achievement of one or more objectives selected from the above-mentioned viewpoints, such as discomfort and manufacturing costs.

[0036] Unless otherwise specified, in drawings, "up" refers to the upward direction or upper side, and "down" refers to the downward direction or lower side. Also, the Z-axis direction is also called the up-and-down direction, the X-axis direction is also called the left-and-right direction, and the Y-axis direction is also called the front-and-back direction. Furthermore, the X-axis direction is also called the approximate horizontal direction, the Z-axis direction is also called the approximate vertical direction, and the Y-axis direction is also called the depth direction.

[0037] 2.This first technology

[0038] This first technology is a storage bag having a surface fiber sheet portion on at least one surface of the bag body, The bag body and the surface fiber sheet are welded to each other at the outer edge of the bag body. The surface fiber sheet portion is It comprises a first fiber sheet section and a second fiber sheet section, An overlapping portion formed from a partial overlap between the first fiber sheet portion and the second fiber sheet portion, which can be opened and closed for inspecting the surface and / or interior of the bag, The storage bag comprises a partially welded portion at both ends of the overlapping portion where the first fiber sheet portion and the second fiber sheet portion are partially welded together, and the storage bag is preferably an ostomy appliance. Preferably, the storage bag further includes a first fiber sheet portion and / or a second fiber sheet portion, where one or more edges other than the outer edge that is welded to the outer edge of the bag body are treated with a dissolving process, and the dissolving process is preferably a heat treatment.

[0039] The first technology and its configuration are described in detail below. The ostomy appliance of the first technology preferably comprises a bag body including a containment section capable of containing excrement. The bag body preferably further comprises the surface fiber sheet portion described above. The bag body may also comprise the dissolution-treated edge portion described above. The bag body may be either open or closed. The bag body may be either one-piece or two-piece.

[0040] An open-type bag is preferably equipped with an outlet that includes a discharge passage for passing waste from the stoma through after the waste has been temporarily contained in the bag. This open-type bag is equipped with a discharge passage and an outlet at the bottom of the bag, and the outlet is configured to allow adjustment between closing and opening, so that waste can be stored in the bag by closing the outlet and then discharged to the outside at any time. In the case of an open type, the bag may be configured to be reusable multiple times by repeatedly discharging and storing waste, or to be emptied and reused for storage. Examples of open types include, but are not limited to, the following first and second embodiments.

[0041] A closed-type bag may generally be configured as a disposable, non-reusable bag. Examples of closed-type bags include, but are not limited to, the following third embodiment.

[0042] The ostomy appliance of this first technology may further include an outlet section that includes an outlet passage for passing excrement, as appropriate. The outlet section in this first technology is not particularly limited, and any configuration, type, or shape of the outlet section may be selected (for example, there may be a mouthpiece type, a folding type, a clip type, etc.), and the shape of the surface fiber sheet section may be appropriately adjusted to match the selected outlet section. In a preferred first embodiment of this first technology, it is preferable that the discharge port in the discharge passage through which excrement passes is equipped with a mouthpiece. A preferred second embodiment of the present first technology is an ostomy appliance in which the outlet portion of the discharge passage through which excrement passes is foldable (rolled up). A preferred third embodiment of this first technology is a bag shape that does not have an outlet or discharge passage.

[0043] This allows the bag body to have a surface fiber sheet portion on at least one surface, which has a structure that allows for internal inspection using a fiber sheet portion, resulting in good bonding strength between the bag body and the surface fiber sheet portion having said structure, while also reducing manufacturing costs and discomfort during wear.

[0044] Preferred embodiments of this first technology will be described in more detail below, but this technology is not limited thereto.

[0045] 2-1. First Embodiment of the Technology A preferred first embodiment of this first technology will be described with reference to Figures 1 to 4 and 7 to 12, but this technology is not limited to these figures.

[0046] A preferred ostomy appliance 100 in the first embodiment of the present technology comprises a surface fiber sheet portion 10 on at least one surface of the bag body 20. In the first embodiment, it is preferable that the discharge port 50 provided in the discharge passage through which excrement passes is equipped with a spout 51.

[0047] The ostomy appliance 100 in this first embodiment is attached to a stoma created on the body surface and appropriately handles the waste discharged from the stoma. Here, the waste may include solid, semi-solid, or liquid waste, and may also include gaseous waste such as odor-containing gases.

[0048] As shown in Figures 1 and 4, the ostomy appliance 100 may have a bag 20 (also called a pouch) for temporarily containing waste discharged from the stoma, and an adhesive faceplate 60 for fixing the bag 20 to the body (skin) such as the abdomen. The faceplate 60 may be a one-piece or two-piece type.

[0049] The bag body 20 is composed of a first bag body film 21 and a second bag body film 22, where the first bag body film 21 may be the non-skin side or front wall, and the second bag body film 22 may be the skin side or back wall. Furthermore, the bag body 20 may have one or more additional bag body films to appropriately define the space inside the bag body. Also, when viewed from the front, the bag body may have one or more constrictions or cavities. This allows for the formation of multiple spaces inside the bag body, making it easier to contain excrement; the constrictions make it easier to grasp, etc.

[0050] The bag body 20 can be formed by joining and closing the outer edges of two or more films by heat or other means. The bag body 20 may be formed using two or more bag body films made of transparent or opaque plastic, and it is preferable to form it by welding the outer edge regions of the bag body films. The first bag body film 21 and / or the second bag body film 22 may be transparent or opaque. From the viewpoint of internal inspection, it is preferable that at least a part of the first bag body film 21 is transparent. It is preferable that the first bag body film 21, which becomes the surface of the bag body on the non-skin-contacting side, is transparent, and the second bag body film 22, which becomes the back surface of the bag body on the skin-contacting side, is opaque.

[0051] As the material for the bag film, it is preferable to use a synthetic resin material that has high tear strength, seal strength, flexibility, and excellent water resistance in order to prevent leakage of excrement and odor. Specific examples of the bag film material are not particularly limited, but include polyolefins such as polyethylene, low-density polyethylene, high-density polyethylene, and polypropylene; olefin copolymers such as ethylene-vinyl acetate copolymer (EVA), ethylene-ethyl acrylate copolymer (EEA), ethylene-methyl acrylate copolymer (EMA), ethylene-methyl methacrylate copolymer (EMMA), ethylene-methacrylic acid polymer (EMAA), and ethylene-acrylic acid copolymer (EAA); polyvinyl chloride, polyvinylidene chloride; polyamides such as nylon 6 and nylon 66; polyesters such as polyethylene terephthalate and polybutylene terephthalate; polyvinyl alcohol; and polyurethane. These synthetic resin materials may be used individually or mixed in combination of two or more types, and the film layer structure may be a single-layer film or a multi-layer film made by laminating multiple layers.

[0052] The bag film may be transparent, opaque, or a combination of both. From the standpoint of being able to see the excrement contained in the bag, transparency is preferred, and transparency may be reduced by embossing or other methods. In the case of opaque films, examples include films with accessories (such as surface coatings with patterns or pictures) and colored films (for example, films in skin-like colors), but are not limited to these. Examples of skin-like colors include orange, pink, khaki, brown, yellow, white, and black, and one or more of these can be selected.

[0053] The thickness of the bag film (one sheet) is not particularly limited, but a suitable lower limit is preferably 40 μm or more, more preferably 50 μm or more, and a suitable upper limit is preferably 200 μm or less, more preferably 100 μm or less, and a suitable numerical range is preferably about 40 μm to 200 μm, more preferably 50 to 100 μm.

[0054] The shape of the bag film is preferably the shape as seen from the front of the non-skin-attached side. The shape and size of the bag film on the skin-attached side and the bag film on the non-skin-attached side are preferably the same, which makes it easier to form the bag by welding them together after aligning their outer edges. The shape of the bag film is preferably composed of the shape of the containment section and the shape of the discharge passage. For example, as shown in Figures 7 and 8, it can be composed of a large, vertically elongated, roughly rectangular containment section and a smaller, vertically elongated, roughly rectangular discharge passage.

[0055] The shape of the bag film (container section, discharge passage) is not particularly limited and can be, for example, a polygonal shape or a roughly circular shape. The polygonal shape is not particularly limited and can be, for example, a roughly square shape (roughly rectangular, roughly square, roughly rhombus, roughly trapezoid), a pentagon, etc. The roughly circular shape is not particularly limited and can be, for example, a roughly elliptical shape or a roughly perfect circle. The polygonal shape may also have rounded corners. These may also have a constricted shape. These may be elongated vertically or horizontally horizontally, but elongated vertically is preferred. One or more of these can be selected.

[0056] The shape and size of the fiber sheet and surface fiber sheet portion described later can be appropriately adopted from the shape and size of the film or bag body described above. It is preferable that the shape and size of the fiber sheet and surface fiber sheet portion be adapted to the shape and size of the film or the bag body after formation. For example, the surface fiber sheet portion may have substantially the same shape and size as the bag body film. For example, by aligning the outer edges of two or more bag body films with the outer edges of the surface fiber sheet portions on the skin-contacting side and the non-skin-contacting side, and appropriately welding and joining these joined outer edges, a bag having surface fiber sheet portions on both sides can be obtained in this technology.

[0057] <Surface fiber sheet portion> A suitable ostomy appliance 100 has a bag body 20 and a surface fiber sheet portion 10 welded to each other at the outer edge of the ostomy appliance 100, and it is preferable that the surface fiber sheet portion 10 is at least the surface fiber sheet portion on the non-skin side. It is preferable that at least the surface fiber sheet portion 30 on the skin side be provided from the viewpoint of reducing discomfort.

[0058] The surface fiber sheet portion 10 is preferably provided on at least one surface of the bag body 20. The surface fiber sheet portion 10 is preferably provided with a first fiber sheet portion 11 and a second fiber sheet portion 12. The surface fiber sheet portion 10 is preferably provided with an overlapping portion 2 that can be opened and closed for checking the interior, formed from a partial overlap of the first fiber sheet portion 11 and the second fiber sheet portion 12, and a partially welded portion 3 at both ends of the overlapping portion 2 where the first fiber sheet portion 11 and the second fiber sheet portion 12 are partially welded to each other.

[0059] A more suitable ostomy appliance 100 is preferably equipped with surface fiber sheet portions 10, 30, and is preferably formed from a bag body 20 and surface fiber sheet portions 10, 30.

[0060] The fiber sheet used in the surface fiber sheet portion is not particularly limited, but examples include woven fabrics, knitted fabrics, and nonwoven fabrics. By using a fiber sheet, negative elements that cause discomfort can be reduced. For example, by using a fiber sheet, noise (such as rustling sounds) caused by the bag film during operation can be reduced. Of these, woven fabrics and knitted fabrics are preferred, and woven fabrics are more preferred. Generally, woven fabrics are also called textiles, and woven fabrics refer to those in which warp and weft threads are intertwined. When woven fabric is used as a fiber sheet, it is superior to when nonwoven fabric is used as a fiber sheet in terms of appearance and feel (for example, dampness and stickiness due to perspiration, showering, or bathing).

[0061] The fibrous materials used in the fiber sheets are not particularly limited, but examples include natural fibrous materials (plant materials such as cotton, hemp, and silk; animal materials such as wool; etc.) and chemical fibrous materials (for example, synthetic resin fibers, etc.), and these can be used individually or in combination of two or more types. Furthermore, examples of fiber materials used in fiber sheets include polyester materials, polyolefin materials (polyethylene materials, polypropylene materials), cellulose materials (including cotton, piece coarse rayon, polynosic, copper ammonia rayon, lyocell, etc.), polyurethane materials, acrylic materials, polyamide materials, polyvinyl chloride materials, and polyvinylidene chloride materials. Of these fiber materials, thermoplastic synthetic resin fiber materials are preferred for use in fiber sheets from the viewpoint of ease of welding and a smooth texture with less pilling. These can be used individually or in combination of two or more types.

[0062] The thickness of the fiber sheet layer is not particularly limited, but a suitable lower limit is preferably 25 μm or more, more preferably 50 μm or more, and even more preferably 100 μm or more. A suitable upper limit is preferably 1000 μm or less, more preferably 500 μm or less, and even more preferably 300 μm or less. A suitable numerical range is more preferably 25 to 1000 μm, and even more preferably 100 to 300 μm.

[0063] If the fiber sheet material is a woven fabric material, a suitable woven fabric material is preferably 2.54 cm 2 The woven fabric has a yarn density (weave density) of 70 to 110 warp threads and 60 to 100 weft threads per square inch, more preferably 80 to 100 warp threads and 70 to 90 weft threads. A suitable woven fabric material may preferably have a tensile strength of 80 to 160 N in the warp direction (flow direction) and 80 to 140 N in the weft direction (width direction), more preferably 100 to 140 N in the warp direction (flow direction) and 100 to 120 N in the weft direction (width direction). The woven fabric material may have a water-resistant finish. For example, it may include a polyester woven fabric with a water-repellent finish. The water-repellent finish may be silicone-based or fluorocarbon-based. The water-repellent treatment may be dye heat-set or boil-off heat-set.

[0064] A more preferable surface fiber sheet portion 10 comprises a first fiber sheet portion 11 and a second fiber sheet portion 12, and preferably includes an openable and closable overlap portion 2 formed from a partial overlap of the first fiber sheet portion 11 and the second fiber sheet portion 12 for checking the surface and / or interior of the bag 20, and a partially welded portion 3 at both ends of the overlap portion 2 where the first fiber sheet portion 11 and the second fiber sheet portion 12 are partially welded to each other.

[0065] It is preferable that the overlapping portion 2 is formed from a partial overlap between the first fiber sheet portion 11 and the second fiber sheet portion 12. By opening and closing the overlapping portion 2, the surface and / or interior of the bag body 100 located in the direction of skin contact (inward direction) from the surface fiber sheet portion 10 can be checked. When viewed from the front, the length of the overlapping portion in the shorter direction is preferably the length (L1) between the edge 14 (dashed line) of the second fiber sheet portion 12 and the edge 13 (solid line) of the first fiber sheet portion. When viewed from the front, the longitudinal length of the overlapping portion is preferably the length (L2) from end to end of the first fiber sheet portion 11 and the second fiber sheet portion 12, or it may be the length of both ends in the longitudinal direction. Alternatively, the longitudinal length of the overlapping portion may be the distance between both ends of the overlapping portion, and it is preferable that each end is the outermost edge of the outer periphery.

[0066] When viewed from the front, it is preferable that all or part of the overlapping portion 2 overlaps the stoma opening 6. More preferably, when viewed from the front, it is preferable that the entire area of ​​the overlapping portion 2 overlaps the stoma opening 6. This ensures that when the overlapping portion is closed, the inside is not visible to others, while when the overlapping portion is open, the stoma and the area around the stoma are easily visible, and the condition of the surface of the bag 20 and the amount of waste contained within it can also be easily checked.

[0067] The overlapping portion 2 is preferably configured to be openable and / or closable in order to check the surface and / or interior of the bag body 20. As shown in Figure 1, the surface fiber sheet portion 10 with the overlapping portion 2 is on the non-skin side, so the bag body 20 inside the surface fiber sheet portion 10 is not visible. This prevents others from seeing the bag body or the excrement contained within it, thus reducing discomfort. As shown in Figure 2, the overlapping portion 2 can be opened with a finger or the like, and the opened overlapping portion 2 allows for checking the interior in the direction of the stoma opening from the surface fiber sheet portion 10. Thus, the overlapping portion 2 can also have an openable and closable window function.

[0068] The interior that can be inspected using the overlapping portion 2 preferably includes, for example, the surface and the interior of the bag. In addition to visual inspection by the user, the interior may also be inspected using external cameras, sensors, or other devices. Furthermore, the means for opening the overlapping portion 2 is not particularly limited as long as the overlapping portion 2 can be opened, and may include an opening and closing device or means that can perform an opening and closing operation on the overlapping portion.

[0069] The shape or size of the overlapping portion is preferably such that at least a region of partial welding with appropriate bonding strength can be formed at both ends of the overlapping portion of the surface fiber sheet and at the outer edge of the bag.

[0070] The shape of the overlapping portion is not particularly limited, but examples include, but is not limited to, a roughly rectangular, roughly elliptical, or roughly arc-shaped shape. A strip-shaped overlapping portion is preferable from the viewpoint of heat welding treatment to prevent fraying.

[0071] The length of the overlap is not particularly limited, but it is preferable, however, that the lower edge 13 of the first fiber sheet portion 11 and the upper edge 14 of the second fiber sheet portion overlap in such a way that the bag body 20 is not visible from the front of the non-skinned side. For example, the edge 13 of the first fiber sheet portion 11 and the edge 14 of the second fiber sheet portion 12 may be in contact with each other, or the edge 13 of the first fiber sheet portion 11 may overlap so as to cover the edge 14 of the second fiber sheet portion 12, or the edge 14 of the second fiber sheet portion 12 may overlap so as to cover the edge 13 of the first fiber sheet portion 11.

[0072] The length (L1) of the overlap in the short direction of the overlapping portion is not particularly limited, but a preferred lower limit is preferably 5 mm or more, more preferably 10 mm or more, and even more preferably 15 mm or more. A preferred upper limit is preferably 30 mm or less, more preferably 25 mm or less, and even more preferably 20 mm or less. A preferred numerical range is preferably 5 to 30 mm, and more preferably 10 to 25 mm. By setting the overlap of the overlapping portion of the surface fiber sheet portion to this range, even if the bag expands with excretory substances such as gas, the inside of the bag can be covered with the surface fiber sheet portion without the inside of the bag being exposed. The length of the overlap in the short direction of the overlapping portion may also be the length of the overlapping portion shape in the short direction.

[0073] The longitudinal length (L2) of the overlapping portion is not particularly limited, but is preferably substantially the same as the transverse length of the bag. The longitudinal length (L2) of the overlapping portion 2 is preferably 50 mm or more, more preferably 60 mm or more, and even more preferably 70 mm or more as a preferred lower limit, and preferably 240 mm or less, more preferably 220 mm or less, and even more preferably 200 mm or less as a preferred upper limit, and the preferred numerical range is preferably 50 to 240 mm, and more preferably 60 to 220 mm. The longitudinal length of the overlapping portion may also be the longitudinal length of the overlapping portion shape.

[0074] The inclination of the overlapping portion when viewed from the front is not particularly limited, but may be approximately horizontal, approximately vertical, or diagonal (for example, diagonally downward to the right, diagonally downward to the left), and may be any of the 360 ​​degrees. Furthermore, the inclination of the overlapping portion may be expressed as 0 degrees for the approximately horizontal direction when viewed from the front, with the center of the overlapping portion as the axis of rotation, and expressions such as 0 to 360 degrees, ±90 degrees, ±45 degrees, ±30 degrees, ±15 degrees, ±10 degrees, ±5 degrees may be used. For example, the horizontally elongated overlapping portion 2 as shown in Figure 1 may be an overlapping portion in the approximately horizontal direction or an overlapping portion with an inclination of ±10 degrees thereto, and the vertically elongated overlapping portion 302 as shown in Figure 6 may be an overlapping portion in the approximately vertical direction or an overlapping portion with an inclination of ±10 degrees thereto.

[0075] Furthermore, if the overlapping portion is in the shape of a horizontally elongated strip as shown in Figure 1, it is preferable that the lower edge 13 of the first fiber sheet portion 11 covers the upper edge 14 of the second fiber sheet portion 12. This is preferable because when the overlapping portion is closed, the lower edge 13 becomes a horizontal line due to its own weight, which looks good. The edge on the covering side (for example, the solid line indicated by reference numeral 13) may be inclined diagonally downwards to the left and right. Furthermore, if the overlapping portion is in the shape of a vertically elongated strip as shown in Figure 6, the configuration may be such that the edge 313 of the first fiber sheet portion 311 covers the edge 314 of the second fiber sheet portion 312, or the edge 314 of the second fiber sheet portion 312 covers the edge 313 of the first fiber sheet portion 311. The edge on the covering side may be either the line segment of reference numeral 314 or the line segment of reference numeral 313. In the former case, line segment 314 is a solid line and line segment 313 is a dashed line, and in the latter case, line segment 313 is a solid line and line segment 314 is a dashed line.

[0076] <Partial weld area> In this technology, the partially welded portion 3 is preferably formed by partially welding the first fiber sheet portion 11 and the second fiber sheet portion 12 together at both ends of the overlapping portion 2, and it is preferable that both ends of the overlapping portion 2 be positioned at the outermost edge of the outer edge 4, from the viewpoint of preventing fraying of the fiber sheet (see Figures 1, 3-1 and 3-2, etc.). The partially welded portion may be one or more, but it is preferable that there be two or more, from the viewpoint of joint strength.

[0077] In a more preferred embodiment of this technology, the partially welded portion 3 is preferably formed on the surface fiber sheet portion 10 when it is formed from the first fiber sheet portion 11 and the second fiber sheet portion 12. The partially welded portion 3 is preferably formed by welding a predetermined area on the non-joined surface and / or the joined surface of the bag film, and at least a predetermined area on the non-joined surface of the bag film is preferably welded. More preferably, from the viewpoint of bonding strength, the partially welded portion 3 is formed by welding a predetermined area on both surfaces.

[0078] It is more preferable to provide a predetermined area on the joint surface of the bag film that includes a welding treatment area for forming a partially welded portion 3 and a non-welding treatment area. The ratio of the area of ​​the non-welding treatment area on the joint surface of the bag film is preferably 1% or more, more preferably 5% or more, and even more preferably 10% or more, when the area of ​​the predetermined area on the joint surface is taken as 100%, from the viewpoint of bonding strength after the formation of the partially welded portion, and preferably 99% or less, more preferably 95% or less, and even more preferably 90% or less, when the area of ​​the predetermined area on the joint surface is taken as 100%. The ratio of the area of ​​the non-welding treatment area in the predetermined area on the non-joint surface of the bag film can be appropriately adopted from the ratio of the area of ​​the non-welding treatment area described above.

[0079] In a more preferable embodiment of this technology, it is preferable that the partially welded portion 3 is further formed by a welding process from the non-joined surface of the bag film, from the partially welded portion 3 formed on the surface fiber sheet portion 10 from the first fiber sheet portion 11 and the second fiber sheet portion 12 and the outer peripheral edge 4. In this technology, the ostomy appliance can include an overlapping portion 2 that can be opened and closed for checking the inside of the surface fiber sheet portion 10, and partially welded portions 3 at both ends of the overlapping portion 2 in which the first fiber sheet portion 11 and the second fiber sheet portion 12 and the bag film 20 are partially welded together.

[0080] The partially welded portion 3 may be included in a predetermined region 7 of the surface fiber sheet portion 10, which includes a welded area and a non-welded area, and the partially welded portion 3 may be a welded area. The predetermined region 7 including the partially welded portion 3 may contain one or more partially welded portions 3. Preferably, the predetermined region 7 including the partially welded portion 3 is a region that includes at least the outer edge 4 of the bag body 20 or a region that partially or completely overlaps with the outer edge 4.

[0081] As shown in Figures 1 and 3, the positional relationship between a predetermined region 7 containing a partially welded portion 3 and the outer peripheral edge 4 of the bag 20 is such that the predetermined region 7 may intersect or touch the outer peripheral edge 4, or it may be positioned to protrude inward from the outer peripheral edge 4 in an oblique or lateral direction. Furthermore, the predetermined region 7 may be positioned along the outer peripheral edge 4, or it may be positioned so that it partially or completely overlaps the outer peripheral edge 4. Preferably, the predetermined region 7 is positioned along the outer peripheral edge 4 and within the range of the outer peripheral edge 4. More preferably, the predetermined region 7 is positioned such that a part or all of one of the partially welded portions 3 is located at the outermost edge of the outer peripheral edge 4.

[0082] The predetermined region 7 including the partially welded portion 3 may be a predetermined region 7 composed of a first welded portion 31 and a second welded portion 32, or it may be a predetermined region 7 including the first welded portion 31 and the second welded portion 32 and a non-welded treatment region. The first welded portion and the second welded portion may be a first welding treatment region and a second welding treatment region, respectively.

[0083] The surface fiber sheet portion used in this technology allows for partial welding to the bag film, thereby enabling the ostomy appliance to have partially welded portions only at both ends of the overlapping section. These partially welded portions firmly connect the first fiber sheet portion, the second fiber sheet portion, and the bag film, while these three components have non-jointed portions. Therefore, based on the firmly joined partially welded portions at both ends of the overlapping section, the opening and closing operation of the overlapping section can be easily performed, and repeated opening and closing operations are possible.

[0084] From the viewpoint of bonding strength, reduction of discomfort when wearing the ostomy appliance, and reduction of manufacturing costs, it is preferable that the cross-sectional state of the partially welded portion 3 is such that the first fiber sheet portion and the second fiber sheet portion are not in a state of complete film formation, but rather that there is a state of welding between the film and the fibers. When the total cross-sectional area of ​​the cross-sectional state of a predetermined region 7, which includes the aforementioned welded and non-welded regions, is taken as 100%, the proportion of the cross-sectional area of ​​the film formation is preferably 1% or more, more preferably 5% or more, and even more preferably 10% or more as a suitable lower limit, and preferably 99% or less, more preferably 95% or less, and even more preferably 90% or less as a suitable upper limit.

[0085] For example, as shown in Figure 9, it is preferable that, in one or more regions welded from the non-joined surface of the bag to the surface fiber sheet portion formed by welding from the first fiber sheet portion and the second fiber sheet portion, a part or all of the first fiber sheet portion and a part of the second fiber sheet portion are welded together to form a film, and the portion of the second fiber sheet portion that was not filmed with the first fiber sheet portion is welded to the bag film. In other words, when welding the two surface fiber sheet portions, by leaving a portion of the second fiber sheet portion that is not welded with the first fiber sheet portion (non-welded portion), the resin of the bag film is impregnated into the remaining fiber portion of the second fiber sheet portion that has not been filmed (non-welded portion), and the second fiber sheet portion and the bag film can be easily welded together. In this specification, "film formation" refers to a state in which, when a predetermined portion of a laminated sheet including a fiber sheet is welded, the fiber portion of the fiber sheet is not visible in cross-sectional observation of the predetermined portion, and the fiber sheet has dissolved and solidified to form a single layer like a film (see, for example, Comparative Example 1 in Figure 11). In this specification, "incomplete film formation" refers to a state in which, after the welding treatment described above, the cross-section shows a state in which the remaining fibers (also called the "fiber layer") and the film formation region coexist, and may include a region in which the film of the bag is impregnated into the fibers (also called "fiber-film impregnation") (see, for example, Example 1 in Figure 11). Note that cross-sectional observation of the predetermined portion may be performed using a microscope.

[0086] As a suitable example of manufacturing a partially welded portion, a fiber sheet portion containing a partially welded portion is obtained by performing a welding treatment on a welding treatment area provided on a surface fiber sheet portion formed from a first fiber sheet portion and a second fiber sheet portion, from the surface of the first fiber sheet portion which is the non-joined surface of the bag film; welding treatment is performed on the welding treatment area of ​​the fiber sheet portion (e.g. outer edge) and the welding treatment area of ​​the bag film (e.g. outer edge) from the non-joined surface of the bag film; the three-dimensional cross-sectional state of the resulting welding treatment area (e.g. outer edge) in the downward direction is not a state of complete film formation, but a state in which welding between the film and fibers exists (see, for example, the upper part of Figure 9). Here, "downward direction" refers to the downward direction from the fiber sheet portion to the bag film. Furthermore, when the partially welded portion of the surface fiber sheet portion formed from the first and second fiber sheet portions and the first and second bag films are welded at a predetermined portion, the "bag" layer, which is the lower layer of the "joining with the bag" layer in the upper part of Figure 9, becomes the film layer after the welding treatment in which the first and second bag films are joined or welded.

[0087] As a more suitable example of manufacturing a partially welded portion, a planar partially welded portion composed of multiple welded and unwelded portions is placed on the surface of the first fiber sheet portion; the first fiber sheet portion and the second fiber sheet portion are placed in contact with each other, and welding is performed on the multiple welded portions in the partially welded portion from the surface of the first fiber sheet portion, which is the unjointed surface of the bag film, to obtain a fiber sheet portion in which a partially welded portion composed of welded and unjointed portions is formed inside; welding is performed on the welded portion of the fiber sheet portion (e.g. outer edge) and the welded portion of the bag film (e.g. outer edge) from the unjointed surface of the bag film; the three-dimensional cross-sectional state downward of the resulting welded portion (e.g. outer edge) is not a state of complete film formation, but a state in which welding exists between the film and the fibers. Furthermore, the bag film below the welded portion on the surface of the first fiber sheet is not a complete film but is partially film-formed, and the bag film below the non-welded area on the surface of the first fiber sheet is not a complete film but is partially film-formed, and the fibers of the second fiber sheet are impregnated with the bag film. As a result, a fiber sheet with higher bonding strength is more easily obtained (see, for example, the lower part of Figure 9). Here, "downward" refers to the downward direction from the fiber sheet to the bag film. When the partially welded portion of the surface fiber sheet formed from the first and second fiber sheet portions and the first and second bag films are welded at a predetermined portion, the "bag" layer, which is the layer below the "joining with the bag" layer in the lower part of Figure 9, becomes a film layer after welding, in which the first and second bag films are joined or welded.

[0088] The shape of the partially welded area is not particularly limited and can be, for example, a linear shape (straight line, curved line, etc.) or a dot shape. The linear shape may be a line with thickness in its width, for example, a thick line that is roughly rectangular, and the curved shape may be a roughly circular or elliptical shape with thickness in its width. These shapes may be rotated by any angle between 0 and 360 degrees with the center as the axis of rotation. Examples of linear shapes include vertical lines, horizontal lines, diagonal lines sloping downwards to the right, and diagonal lines sloping downwards to the left, and may be combinations of two or more of these, for example, a cross grid shape or a diagonal line grid shape. Examples of dot shapes include x-shaped dots, cross dots, and round dots. The shape of the partially welded area may also be striped. The shape of the partially welded area may also be a pattern consisting of linear shapes and / or dot shapes.

[0089] The shape and arrangement of the partially welded portion will be explained in more detail in Figures 3-1 and 3-2. Here, the vertical direction refers to the Z-axis direction in Figure 1 or the longitudinal direction of the bag. The longitudinal length of the predetermined region 7 including the partially welded portion 3 may be the same as the vertical length of the overlapping portion 2, and the short-side length of the predetermined region may be the width of the edge of the outer peripheral edge 4 (short-side length).

[0090] As shown in Figure 3-1, the partially welded portion 3A is composed of a single elongated shape along the vertical direction, and a vertically elongated rectangular shape is preferred. The partially welded portion 3A is preferably included in a predetermined region 7A within the outer peripheral edge 4, and it is preferable that the predetermined region 7A includes a non-welded area on a plane.

[0091] The partially welded portion 3B is a stripe-like pattern composed of two or more elongated vertical shapes along the vertical direction, and a vertically elongated rectangular shape is preferred. The partially welded portion 3B is preferably included in a predetermined region 7B within the outer peripheral edge 4, and the predetermined region 7B preferably includes a non-welded area on a plane.

[0092] The partially welded portion 3C is a stripe-like pattern composed of one or more (e.g., four) horizontally elongated shapes along the left-right direction, and a horizontally elongated rectangular shape is preferred. The partially welded portion 3C is preferably included in a predetermined region 7C within the outer peripheral edge 4, and the predetermined region 7C preferably includes a non-welded area on a plane.

[0093] The partially welded portion 3D is a pattern composed of multiple circular dots. The partially welded portion 3D is preferably included in a predetermined region 7D within the outer edge 4, and the predetermined region 7D preferably includes a non-welded area on a plane.

[0094] Partially welded area 3E is a pattern composed of multiple x-shaped dots. Partially welded area 3F is a stripe pattern composed of elongated horizontal rectangles. Partially welded area 3G is a stripe pattern composed of elongated diagonal lines, which may be downward sloping to the right or left. Partially welded area 3H is a diagonal grid shape, which may also be a diagonal grid pattern. It is preferable that each of these partially welded areas 3E to 3H is contained within a predetermined area 7 within the outer edge 4, and it is preferable that the predetermined area 7 includes a non-welded area on a plane.

[0095] The partially welded portion 3 shown in Figure 3-2 is preferably composed of a first welding treatment area 31 and a second welding treatment area 32, and each of these welding treatment areas may include a non-welding treatment area. One partial welded portion 3 in the first welding area 31 is preferably located at the outermost edge of the outer edge 4, and the second welding area 32 is preferably located inward from the first welding area 31, and may be located within the outer edge 4, or may be located extending inward from a certain location within the outer edge 4. The inward direction here refers to the central axis direction of the bag. The pattern of the partial welded portion in the second welding area 32 is not particularly limited, and may be one or more combinations selected from, for example, the partial welded portions 3A to 3H shown in Figure 3-1 and the partial welded portions 32a to 32f shown in Figure 3-2. It is preferable that these predetermined areas 7I1 to 7I6 are each included within the outer edge 4, and it is preferable that non-welded areas are included in the planar area of ​​these predetermined areas 7I1 to 7I6.

[0096] The first welded portion 31 in the first welding treatment area 31 within a predetermined area 7 including the partially welded portion 3 is preferably a vertically elongated rectangle, preferably positioned at the outermost edge within the outer edge 4 from the viewpoint of joint strength, and more preferably positioned in contact with the outermost edge from the viewpoint of preventing fraying of the overlapping portion 2. The second welded portion 32 in the second welding treatment area 32 is preferably a linear and / or dot-shaped pattern as described above, for example, a vertical straight line, a horizontal straight line, a diagonal line to the left and right, and more preferably a stripe-like pattern of these. The second welding treatment area 32 is preferably to include a non-welded area from the viewpoint of joint strength. A dot-shaped pattern is even more preferable from the viewpoint of joint strength and inconspicuousness.

[0097] The ratio of the first welding treatment area 31 and the second welding treatment area 32 in a predetermined region 7 including the partially welded portion 3 is not particularly limited, but it is preferable that the second welding treatment area 32 is larger than the first welding treatment area 31. When the predetermined region 7 (area) is set to 100%, the ratio of the first welding treatment area 31 (area) is preferably 50% or less, more preferably 40% or less, and even more preferably 30% or less as a suitable upper limit, and preferably 1% or more, 2% or more, 3% or more, 4% or more, or 5% or more as a suitable lower limit. The non-welded treatment area in the second welding treatment area 32 is not particularly limited, but it is preferably 20% or more, more preferably 30% or more as a suitable lower limit, and preferably 80% or less, more preferably 75% or less as a suitable upper limit.

[0098] The width of the outer edge is not particularly limited, but a suitable lower limit is preferably 0.1 mm or more, more preferably 0.5 mm or more, and even more preferably 1 mm or more. A suitable upper limit is preferably 20 mm or less, more preferably 15 mm or less, and more preferably 10 mm or less. The width of the outer edge may be the length in the shorter direction of the outer edge, or the length in the X-axis direction.

[0099] The longitudinal length of the partially welded portion is not particularly limited, but is preferably the same as or within the range of the longitudinal length of the predetermined region 7. A preferred lower limit is preferably 0.1 mm or more, more preferably 0.2 mm or more, and even more preferably 0.3 mm or more. A preferred upper limit is preferably 35 mm or less, and more preferably 30 mm or less. The longitudinal length may also be the length in the X-axis direction.

[0100] The length of the partially welded portion in the short direction is not particularly limited, but is preferably the same as or within the range of the length of the predetermined region 7 in the short direction. A preferred lower limit is preferably 0.1 mm or more, more preferably 0.2 mm or more, and even more preferably 0.3 mm or more. A preferred upper limit is preferably 20 mm or less, preferably 15 mm or less, and preferably 10 mm or less. The length in the short direction may also be the length in the Z-axis direction.

[0101] The longitudinal length of the predetermined area is not particularly limited, but is preferably the same as or within the range of the short-side length (L1) of the overlapping portion. A preferred lower limit is preferably 0.5 mm or more, more preferably 1 mm or more, and even more preferably 1.5 mm or more. A preferred upper limit is preferably 30 mm or less, more preferably 25 mm or less, and more preferably 20 mm or less. The longitudinal length may also be the length in the X-axis direction.

[0102] The length in the shorter direction of the predetermined area is not particularly limited, but is preferably the same as or within the width of the outer edge. A preferred lower limit is preferably 0.1 mm or more, more preferably 0.5 mm or more, and even more preferably 1 mm or more. A preferred upper limit is preferably 20 mm or less, preferably 15 mm or less, and preferably 10 mm or less. The length in the shorter direction may also be the length in the Z-axis direction.

[0103] The welding process is not particularly limited, but examples include heat, ultrasound, high frequency, and laser treatments, from which one or more can be selected. The treatment may also be a method of welding the seal.

[0104] The conditions for the welding process when forming the surface fiber sheet are not particularly limited as long as they allow for the formation of a partially welded state on the fiber sheet. However, the preferred treatment temperature is ±20°C above the melting point of the fiber sheet material, more preferably ±10°C above the melting point of the fiber sheet material, and even more preferably ±5°C above the melting point of the fiber sheet material. As an example, a preferred lower limit is preferably 150°C or higher, more preferably 160°C or higher, even more preferably 170°C or higher or 180°C or higher. A preferred upper limit is preferably 400°C or lower, more preferably 390°C or lower, even more preferably 380°C or lower, and even more preferably 370°C or 360°C or lower, and may be within the range of 180°C to 360°C. The welding time for forming the surface fiber sheet portion is not particularly limited, but a suitable lower limit is preferably 0.1 seconds or more, more preferably 0.2 seconds or 0.3 seconds or more, and a suitable upper limit is preferably 20 seconds or less, 19 seconds or less, or 18 seconds or less, and may be, for example, about 1 to 3 seconds. When using ultrasound to form the surface fiber sheet, the appropriate frequency and processing time should be selected to enable welding.

[0105] Furthermore, the conditions for the welding process when forming the storage bag from the surface fiber sheet and the bag film are not particularly limited as long as conditions are met that allow for partial welding between the fiber sheet and the bag film. However, the preferred treatment temperature is ±20°C above the melting point of the bag film material, more preferably ±10°C above the melting point of the bag film material, and even more preferably ±5°C above the melting point of the bag film material. As an example, a preferred lower limit is preferably 150°C or higher, more preferably 160°C or higher, even more preferably 170°C or higher or 180°C or higher, and a preferred upper limit is preferably 240°C or lower, more preferably 230°C or lower, even more preferably 220°C or lower, and even more preferably 210°C or 200°C or lower, and may be within the range of 180°C to 220°C. The welding time for forming the storage bag from the surface fiber sheet and the bag film is not particularly limited, but is preferably 1 second or more, more preferably 2 seconds or 3 seconds or more as a suitable lower limit, and preferably 10 seconds or less, 5 seconds or less, or 3 seconds or less as a suitable upper limit, and may be, for example, about 1 to 3 seconds. When using ultrasound to form a storage bag from the surface fiber sheet and the bag body film, the appropriate frequency and processing time should be selected to enable welding.

[0106] Furthermore, it is preferable that the partially welded portion does not contain any additional hot-melt adhesive between the surface fiber sheet portion (e.g., the second fiber sheet portion) and the bag film, from the viewpoint of reducing discomfort during wear and lowering manufacturing costs. Although hot-melt adhesive may be used as needed in the manufacturing of the ostomy appliance from the standpoint of adhesion, it is preferable not to form a hot-melt adhesive layer between the surface fiber sheet portion and the bag film.

[0107] Examples of hot-melt adhesives include polyolefins, ethylene vinyl acetate (EVA), polyurethanes, polyvinylidene chloride (PVDC), silicone rubber, fluoropolymers, polycarbonates, styrene block copolymers, polyesters, polyamides, and polycaprolactones, from which one or more are selected. Furthermore, the hot-melt adhesive may have a maximum thickness or average (mean) thickness of less than 0.5 mm or less than 0.1 mm.

[0108] The ostomy appliance comprises an outlet in the discharge passage through which excrement passes, and a mouthpiece. Preferably, the first fiber sheet portion and / or the second fiber sheet portion may further have one or more heat-treated edges, other than the outer edge that is welded to the outer edge of the bag body.

[0109] <Welding treatment of the edges of fiber sheets> A more preferred embodiment of this first embodiment is an ostomy appliance 100 having a surface fiber sheet portion 10 on at least one surface of the bag body 20, The bag body 20 and the surface fiber sheet portion 10 are welded to each other at the outer peripheral edge 4 of the bag body 20. The surface fiber sheet portion 10 is It comprises a first fiber sheet portion 11 and a second fiber sheet portion 12. An overlapping portion 2, which can be opened and closed for checking the surface and / or interior of the bag body 20, is formed from a partial overlap of the first fiber sheet portion 11 and the second fiber sheet portion 12. At both ends of the overlapping portion 2, the first fiber sheet portion 11 and the second fiber sheet portion 12 are partially welded together to form a partially welded portion 3, An ostomy appliance 100 can be provided, comprising a first fiber sheet portion 11 and / or a second fiber sheet portion 12, each having one or more edges other than the outer edge 4 of the bag body 20 that are subjected to a dissolving treatment, wherein the edges of the first fiber sheet portion 11 and / or the second fiber sheet portion 12 are subjected to a dissolving treatment.

[0110] As shown in the [Examples] below, when a fiber sheet with cut sections is used, fraying occurs from these cut sections. Cutting can be done by methods such as cutting. For example, when a user uses an ostomy appliance containing this fiber sheet, the cut sections of the fiber sheet and the surrounding areas become damaged from use, causing fraying. Since such fraying contributes to discomfort, conventional methods have involved laminating a film onto the fiber sheet and then cutting it to prevent fraying. However, a problem with this film lamination is that it reduces the flexibility of the film, making it difficult to accommodate items such as mouthpieces and other outlet parts. Furthermore, it increases the amount of material used, tends to produce rubbing noises, and the texture of the fiber sheet is not very good. Therefore, the inventors have found that by applying a so-called heat-cutting treatment, which involves dissolving the cut surface of a fiber sheet, the dissolving-treated edges become less prone to fraying, and the storage capacity is ensured while maintaining the texture of the fiber sheet.

[0111] As shown in Figures 7 and 8, it is preferable that the first fiber sheet portion 11 and / or the second fiber sheet portion 12 have one or more edges in addition to the outer edge that is welded to the outer edge 4 of the bag body 20. The edges other than the outer edge are not particularly limited, but examples include the lower edge 13 of the first fiber sheet portion 11, the upper edge 14 and lower edge 15 of the second fiber sheet portion 12, and optionally an edge 70 for containment, and the edge 16 of the opening of the surface fiber sheet portion 40. Furthermore, the second fiber sheet portion 12 may include an edge 70-9 of the portion that contains the discharge port 50. One or more of these can be used. These edges may be before or after the dissolution treatment.

[0112] The edge after the dissolution treatment may be referred to as the dissolved edge portion 9, for example, the dissolved edge portion 9 indicated by reference numeral 9 (9-13, 9-14, 9-15, 9-16, 9-70) in Figure 8. Furthermore, the melting apparatus and melting conditions can be appropriately adapted from the welding treatment technologies described above. For example, the welding apparatus and welding conditions for forming the surface fiber sheet can be appropriately adapted. For example, heat or ultrasound may be used. The treatment temperature for thermal melting is ±20°C of the melting point of the fiber sheet material, and the treatment time is between 1 second and 10 seconds. For example, it may be within the range of 180°C to 360°C for about 1 to 3 seconds. Ultrasonic treatment may also be used, for example, at 40 to 60 J.

[0113] In a preferred embodiment of this first design, it is preferable that the first fiber sheet portion 11 and / or the second fiber sheet portion 12 do not further contain hot-melt adhesive at the melted edge portion 9. Including a hot-melt adhesive layer reduces ease of packaging. In a preferred embodiment of this first design, it is preferable that the overlapping portion 2 in the first fiber sheet portion 11 and / or the second fiber sheet portion 12 is provided with a dissolution-treated edge portion 9. In a preferred embodiment of this first embodiment, the second fiber sheet portion 12 further comprises an outlet portion 50 (preferably a nozzle), and the second fiber sheet portion 12 further comprises an outlet portion housing portion in which the edge of the portion housing the outlet portion 50 is treated with a melting process. In a preferred embodiment of this first design, it is preferable to further provide a surface fiber sheet portion on the surface of the bag body 20 opposite to the surface fiber sheet portion 10, which has a stoma opening whose edge has been treated with a dissolving process.

[0114] <Moutage> In a preferred embodiment, the bag body 20 in the first embodiment described above may further include an outlet portion 50 (preferably a spout). The spout 51 is not particularly limited and may include, but is not limited to, a rotary valve spout, a cap spout, or a double-lock spout. A double-lock spout is a combination of a rotary valve and a cap seal. The spout 51 is preferably capable of sealing the excrement, preventing leakage of the excrement, and controlling the amount of excrement discharged. The discharge port 50 may be molded using a resin material as the raw material and known molding methods such as injection molding. Examples of resin materials that can be used include ultraviolet curing resins, thermoplastic elastomer resins, urethane resins, silicone resins, synthetic rubbers, natural rubbers, and thermoplastic resins, with flexible resins being preferred.

[0115] As an example, a cap-type mouthpiece 51 is given, but this technology is not limited thereto. The cap-type mouthpiece 51 preferably comprises an attachment portion attached to the discharge passage of the bag body 20, a flexible cylindrical portion through which excrement flows, and a sealing portion 52 for sealing the discharge of excrement to the outside, and more preferably further comprises a cap 54 inserted into the sealing portion 52 to seal the flow of the contents. The cap may have one or more pleats. The cross-sectional shape substantially perpendicular to the central axis of the cylindrical portion or sealing portion is not particularly limited, but examples include polygonal shapes, substantially rectangular shapes with rounded corners, substantially circular shapes, and elliptical shapes. The cap-type mouthpiece 51 may be an integrally molded product consisting of a cap 54 and a connecting part for connecting to the cap. The mouthpiece 51 and the cap 54 are preferably molded from the same resin material, and a flexible resin material is more preferable.

[0116] <Face plate> The panel 60 is not particularly limited and may include, but is not limited to, a flat panel, a convex panel, a concave panel, or a panel with tape. The shape of the panel is preferably approximately circular when viewed from the front. The material of the faceplate is not particularly limited, but it is preferable to use a hydrocolloid adhesive containing a hydrophilic material.

[0117] This first embodiment may be either a one-piece or two-piece orthosis. The one-piece orthosis is one in which the faceplate and the housing are integrally formed by heat melting or the like, while the two-piece orthosis is one in which the faceplate and the housing are each constructed as separate parts, and the faceplate and housing are detachable.

[0118] In this first embodiment, the type of ostomy appliance is not particularly limited, but examples include appliances for ileostomy, urostomy, and colostomy, and one or more of these can be selected. For example, in the case of low-viscosity excrement contained in a storage bag for urostomies and ileostomies, a mouthpiece is preferred for the outlet, and in the case of colostomies, a foldable outlet is preferred. In this first embodiment, we have mainly described a storage bag related to ostomy appliances, but the technical concept of this technology can also be applied to various embodiments of excrement storage devices such as drainage bags (drainage pouches), defecation bags, urine collection bags, urine collection bags, and leg bags.

The user can roll up the outlet passage 262 by folding it back multiple times towards the non-skin side. In this state, the user engages the first engaging part 271 with the second engaging part 272. This closes the outlet 250 for containing the waste discharged from the stoma. At this time, the user can easily see the folding position by the fold line 280.

Furthermore, since this technology does not require the use of hot-melt adhesive in its manufacturing method, it is possible to reduce manufacturing costs. Furthermore, in this technology, the partially welded portion of the ostomy appliance can be formed by arranging a surface fiber sheet during the process of welding the outer edge of the bag-like film group. Therefore, it is easy to use conventional facilities or equipment for manufacturing ostomy appliances, which can reduce manufacturing costs. Furthermore, the manufactured ostomy appliance has a surface fiber sheet portion on at least one surface of the bag body, which has a structure that allows for internal inspection using a fiber sheet portion, and the bonding strength between the bag body and the surface fiber sheet portion having said structure is good, manufacturing costs can be reduced, and discomfort during wear can also be reduced.

[0148] The effects of the present invention will be specifically described below with reference to examples. However, the scope of the present invention is not limited to the examples described herein.

[0149] <Tests on partial welding: Examples 1-5 and Comparative Example 1>

[0150] The first and second fiber sheet sections were made of polyester woven fabric (175 μm thick), and the bag body film was made of polyethylene film (75 μm thick). The fiber density of the woven fabric is 94 warp threads x 80 weft threads per 2.54 cm. 2 (1 square inch). The tensile strength of the woven fabric is 125N in the longitudinal direction (flow direction) and 104N in the transverse direction (width direction).

[0151] <Method for measuring fiber yarn density (woven density)> The number of threads in a 2.54 cm square area is measured without applying any load to the woven fabric.

[0152] <Method for measuring tensile strength> The measurement was performed using a digital force gauge AIKOH9500, with a test specimen size of 25mm x 70mm, a gripping distance of 50mm, and a tensile speed of approximately 100mm / min.

[0153] The shape of the surface fiber sheet portion constituting the first fiber sheet portion and the second fiber sheet portion, and the shape of the storage portion of the bag film, were substantially the same in shape and size. The storage portion was cut to form a rectangular shape with rounded corners, as shown in Figure 7. The length of the storage portion in the vertical direction was 22 cm, and the length in the horizontal direction was 14 cm.

[0154] The first and second fiber sheet portions were partially heat-welded at 180-200°C for 1-3 seconds to obtain each surface fiber sheet portion. The number, shape, and pattern of the partially welded portions were as shown in Examples 1-5 and Comparative Example 1 in Figure 10. In Example 1, the vertical length of the partially welded area was approximately 25 mm, and the horizontal length was approximately 3.5 mm. In Example 1, almost the entire surface of the bag that was not joined became a welded area, but almost the entire surface of the bag that was joined became a non-welded area.

[0155] In Example 2, in the partially welded area consisting of welded and non-welded areas on the surface, the vertical length of the vertical sprite (welded area) was approximately 25 mm, and the horizontal length was approximately 1.5 mm, with two such vertical stripes being installed. On the joined and non-jointed surfaces of the bag, the area of ​​the welded area in the partially welded area of ​​Example 2 was approximately 86%, and the area of ​​the non-welded area was approximately 14%.

[0156] In Example 3, in the partially welded area consisting of welded and non-welded areas on the surface, the lateral length of the lateral sprites (welded areas) was approximately 3.5 mm, and the vertical length was approximately 1.5 mm, with four of these lateral stripes being installed. On the joined and non-jointed surfaces of the bag, the area of ​​the welded areas in the partially welded area of ​​Example 3 was approximately 57%, and the area of ​​the non-welded areas was approximately 43%.

[0157] In Example 4, 24 dots (12 dots in two rows) were provided as welding treatment areas in a rectangular area of ​​partial welding approximately 25 mm in the vertical direction and 3.5 mm in the horizontal direction. Each dot had a diameter of approximately 1 mm. On the joined surface and the non-joined surface of the bag, the area of ​​the welding treatment area in the partial welding area of ​​Example 4 was approximately 22%, and the area of ​​the non-welded treatment area was approximately 78%.

[0158] In Example 5, the partially welded area consists of a vertical sprite area (first welded area) measuring approximately 25 mm vertically and 1 mm horizontally, and an area inside it containing 36 dots (12 dots per row, arranged in 3 rows) measuring approximately 25 mm vertically and 3 mm horizontally (second welded area). The area ratio of these two areas is approximately 25% for the first welded area and approximately 75% for the second welded area. On the joined and unjointed surfaces of the bag, the area of ​​the welded area in the partially welded area of ​​Example 5 was approximately 53%, and the area of ​​the unjointed area was approximately 47%.

[0159] The outer edges of the surface fiber sheet and the bag film were partially heat-sealed at 190-200°C for 2-3 seconds, resulting in a three-layer sheet with these three components welded and joined in certain areas. The width of the outer edge was 3.5 mm. The vertical length of the overlap between the first and second fiber sheets in the surface fiber sheet was approximately 25 mm.

[0160] <Evaluation regarding partial welding> As shown in Figure 10, the evaluation focused on the bonding strength between the fiber sheet (woven fabric) and the bag (bag body), texture, inconspicuousness, and resistance to unraveling. The specific evaluation method was as follows: Bonding strength with the bag was evaluated on a two-point scale: ○ (does not peel) and × (peels). Other evaluations were evaluated on a five-point scale: "Poor (1, 2, 3, 4, 5) Good," with a passing score of 3 points or higher.

[0161] <Evaluation of bonding strength with the bag> I pulled on one pouch film and the woven fabric by hand to see if they would separate.

[0162] <Evaluation of skin texture> The welding area was touched with a finger and evaluated based on the degree of discomfort.

[0163] <Evaluation of inconspicuousness> The welded area was visually inspected, and its visibility was evaluated.

[0164] <Evaluation of difficulty in unraveling> The degree to which the fibers of the woven fabric unraveled was evaluated by rubbing the outer edge with a finger.

[0165] As shown in Comparative Example 1 in Figures 10 and 11, a surface fiber sheet portion was obtained by overlapping a portion of the first fiber sheet portion and a portion of the second fiber sheet portion using woven fabric, and then heat-sealing the area from both sides to create a completely three-dimensional film in the depth direction. In this Comparative Example 1, heat-sealing was performed in a horizontally wide, vertically elongated rectangular shape from both the non-jointed surface and the jointed surface of the bag film.

[0166] In Comparative Example 1, when the completely film-formed welded area of ​​the surface fiber sheet and the corresponding area of ​​the bag film were welded together, they did not join and peeled apart.

[0167] As shown in Example 1 in Figures 10 and 11, a portion of the first fiber sheet and a portion of the second fiber sheet were overlapped and heat-sealed on only one side to obtain a surface fiber sheet that was three-dimensionally incomplete in the depth direction. In Example 1, heat-sealing was performed from the non-joined surface of the bag film in a single horizontally wide, vertically elongated rectangular welding region.

[0168] In this first example, by welding the three-layer structure of the surface fiber sheet to the area of ​​the bag film corresponding to the three-layer structure of the surface fiber sheet, a three-layer sheet was obtained in which these three elements were welded and joined in some areas. The state of the welded area at this time was such that the bag film impregnated the fibers along with the film layer, while some fibers remained, resulting in a partially welded layer formed from the three-dimensionally incompletely filmed surface fiber sheet and bag film in the depth direction. Thus, a three-layer structure sheet with a three-dimensional partially welded layer in the downward direction of a certain area on the plane was obtained. The first example exhibited excellent bonding strength, generally good texture and inconspicuousness, and good resistance to unraveling.

[0169] As shown in Example 2 of Figure 10, the first fiber sheet portion and the second fiber sheet portion were brought into contact with the bag film in a welding treatment area such that a partially unwelded portion was left on the surface, and two elongated and narrow rectangular welding treatments were performed from both outer surfaces to obtain a surface fiber sheet portion with a planar incomplete film-forming portion. In this second example, heat welding was performed on both the non-jointed surface and the joined surface of the bag film, using two horizontally parallel, horizontally narrow, vertically elongated welding regions.

[0170] In this second embodiment, a three-layer sheet was obtained in which these three elements were welded and joined in some areas by welding a welding treatment area of ​​the surface fiber sheet having a planar incomplete film-forming portion to the corresponding area of ​​the bag film. At this time, the state of the welded portion was such that the surface fiber sheet portion and the bag film, which were partially welded on the surface, were in a three-dimensionally incomplete film-forming state in the depth direction, and the film of the bag, which was melted by the welding treatment, was impregnated into the fibrous portion of the surface fiber sheet portion that was not partially welded on the surface. In other words, the film of the bag was impregnated into the fibers along with the film-forming layer, while some fibers remained, resulting in a partially welded layer formed from the surface fiber sheet portion and bag film, which were three-dimensionally incomplete film-forming in the depth direction. From this, it was possible to obtain a three-layer sheet having a three-dimensional partially welded layer below a portion of the surface and a film-impregnated layer below the unwelded portion of the surface. Example 2 exhibited excellent bonding strength, generally good texture and inconspicuousness, and good resistance to unraveling.

[0171] In Example 3 of Figure 10, since multiple horizontally elongated partial welded portions were formed, the internal structure formed from the surface fiber sheet portion and the bag film was similar to that of Example 2 above, resulting in a three-layer sheet having a three-dimensional partial welded layer extending downwards in a portion of the surface and a bag film impregnation layer extending downwards in the non-welded portion of the surface. In this Example 3, heat welding was performed on both the non-jointed surface and the joined surface of the bag film, with four short, horizontally elongated and vertically narrow rectangular shapes arranged in a vertical parallel welding region.

[0172] Example 3 exhibited excellent bonding strength, generally good texture and inconspicuousness, and good resistance to fraying. However, because partial welding was formed in the lateral direction, the resistance to fiber fraying was slightly inferior to that of Example 2.

[0173] In Example 4 of Figure 10, since a partially welded area was formed with multiple dots, the internal structure formed from the surface fiber sheet and the bag film was similar to that of Example 2 above, resulting in a three-layer sheet having a three-dimensional partially welded layer extending downwards in a portion of the surface and a bag film impregnation layer extending downwards in the non-welded area of ​​the surface. In this Example 4, heat welding was performed on both the non-jointed surface and the joined surface of the bag film in a welding area with a vertically elongated pattern consisting of 2 horizontal x 12 vertical dots.

[0174] Example 4 exhibited superior bonding strength compared to Examples 1-3, generally had a good feel, was highly inconspicuous, and generally resisted fraying. However, because it formed partial welded areas with multiple dots, its resistance to fiber fraying was inferior to Examples 1-3.

[0175] In Example 5 of Figure 10, a partial welded portion was formed consisting of a first welding treatment area with a single elongated, narrow rectangle at its outermost edge and a second welding treatment area with multiple dots arranged inward. At this time, heat welding was performed from both the non-joined surface and the joined surface of the bag film in a predetermined area including the first heat welding treatment area and the second heat treatment area.

[0176] As a result, an internal structure formed from the surface fiber sheet portion and the bag film was obtained that combined the internal structures of Examples 2 and 4, resulting in a three-layer sheet having a three-dimensional partially welded layer extending downwards in a portion of the surface and a bag film impregnation layer extending downwards in the non-welded portion of the surface. Example 5 had superior bonding strength compared to Examples 1-4, superior texture and inconspicuousness compared to Examples 1 and 4, and good resistance to unraveling, comparable to Examples 1 and 2, which was superior to Examples 3 and 4.

[0177] <Tests on edge dissolution treatment: Examples 1-5 and Comparative Example 1> The woven fabric used was a polyester woven fabric (175 μm thick), and the film (hot melt adhesive) used was a polyethylene film (75 μm thick).

[0178] A bag with a cap-type fastener as shown in Figure 1 was created, and a fiber sheet was cut to the same shape on the non-skin side. For Comparative Example 3, a fiber sheet was used in which woven fabric and film were welded together at 260°C for 1 second. Each fiber sheet was provided with a horizontal cut (36 mm) to accommodate the fastener. For Example 6, a heat melting treatment was performed using an ultrasonic welder at an output value of 50 J, followed by heat cutting. Each fiber sheet and the outer edge of the bag were welded together.

[0179] As shown in Figure 12, we evaluated the following: <fraying after use> and <ease of storage>. The evaluation was done on a three-point scale: × (unacceptable), △ (somewhat poor), and ○ (excellent).

[0180] In Comparative Example 2, repeated insertion of the mouthpiece resulted in fraying at the edge of the portion that houses the discharge port. In Comparative Example 3, the thickness of the film made it difficult to insert and remove the mouthpiece from the edge of the portion that houses the discharge port. In Example 6, there was no film thickness, making it easy to insert and remove the mouthpiece from the edge of the portion that houses the discharge port, and no fraying occurred at the edge of the portion that houses the discharge port even after repeated insertion.
