Description

Technical Field

[0001] This invention relates to a fluid-carrying dressing, particularly a dressing that can modify body surface curves, deliver maintenance / medical fluids, or collect bodily fluids. Background Technology

[0002] Human survival is extremely dependent on fluids, especially air and water. The relationship between the human body and fluids is sometimes a need and sometimes a burden. Needs include urine testing, breast augmentation, skin care, wound care, fever reduction and warmth, hydration, and breastfeeding. Burdens include the handling of bodily fluids (milk, urine, semen, blood).

[0003] While previous technologies have provided several solutions to address the needs and burdens of fluids relative to the human body, they still have many shortcomings. For example, in terms of meeting needs, breast pads tend to slip when used by women with flat breasts, NuBra loses its adhesiveness after repeated use, and surgical implantation of fluid (saline, silicone) bags is painful and expensive. In terms of addressing burdens, infants and bedridden women face the pain and risk of infection when collecting urine through catheterization, and diapers cause various discomforts for those with urinary incontinence, or various urine collection bags are inconvenient to use and prone to leakage. Summary of the Invention

[0004] In view of the aforementioned problems, the present invention provides a fluid-carrying dressing that can temporarily retain fluid on the body surface. It is easy to adhere to the human body, does not easily fall off, and can carry fluids such as water, air, moisturizing solution, medicine, lotion, urine, semen, and blood without leakage. At the same time, it can meet the human body's need for fluids and solve the burden of fluids on the human body. It has a simple structure, is easy to use, has low cost, and has a wide range of applications, which can properly handle the relationship between the human body and fluids.

[0005] To achieve the above objectives, the present invention provides a fluid-carrying dressing, comprising: a first sheet having a first surface and a second surface; a second sheet having a third surface and a fourth surface, wherein a portion of the third surface and a portion of the second surface of the first sheet are fused or bonded to each other in at least a strip-shaped region to form a first chamber having at least a first drainage port, the interior of the first chamber communicating with the outside through the first drainage port; a third sheet disposed between the first sheet and the second sheet, the third sheet and the second sheet forming a second chamber; an adhesive layer disposed on the fourth surface of the second sheet; and a release layer covering at least a portion of the adhesive layer, wherein the first drainage port is an open portion formed on the first sheet or the second surface of the first sheet and the third surface adjacent to the edge of the second sheet that is not fused or bonded to each other. Optionally, it further includes a structural support unit extending from the edge of the first sheet or the second sheet.

[0006] According to one embodiment of the present invention, the edge of the third sheet can be simultaneously fused or bonded between the first sheet and the second sheet, or fused or bonded to the first sheet, or fused or bonded to the second sheet.

[0007] According to one embodiment of the present invention, the edge of the second sheet is larger than the outer edge of the strip region, and the outer edge of the strip region is at a distance from the edge of the second sheet.

[0008] According to one embodiment of the present invention, the device further includes a drainage portion connected to the first drainage port. Optionally, the drainage portion further includes a check valve to prevent fluid from flowing through the drainage portion from the interior to the exterior of the first chamber or from the exterior to the interior of the first chamber. Optionally, the drainage portion is a drainage tube disposed corresponding to the first drainage port. Optionally, the drainage tube is formed by joining the two sides of the second seventh sheet, thereby making the drainage tube flat in its natural state.

[0009] According to one embodiment of the present invention, an isolation material is provided on the inner surface of the drainage portion, and the isolation material is provided by clamping, coating or printing before the drainage portion is formed.

[0010] According to one embodiment of the present invention, the drainage portion is a drainage bag disposed corresponding to the first drainage port. Optionally, the drainage bag is formed by closing all or part of the edges of two seventh sheets, or by closing all or part of the edges of an eighth sheet after folding it in half. Optionally, the first sheet has a first hinged portion, the drainage bag has a second hinged portion larger than the first hinged portion, the first sheet and the drainage bag are closedly connected around the first hinged portion and the second hinged portion, and the first hinged portion is connected to a portion of the second hinged portion. Optionally, it further includes a loop sheet, the loop sheet being connected to the outside of the drainage bag to form a channel for a fixing strap to pass through.

[0011] According to one embodiment of the present invention, the first sheet has an extension portion, which can serve as the aforementioned seventh or eighth sheet, or be used to form a buckle after being folded back.

[0012] According to one embodiment of the present invention, the second sheet has at least one second drainage port, thereby allowing the interior of the first chamber or the interior of the second chamber to communicate with the outside through the second drainage port. The second drainage port is spaced apart from the inner edge of the strip-shaped region. The size of the second drainage port is not particularly limited; for example, it can be a larger opening for connecting the glans penis, female vulva, or nipple, or a small opening only for fluid passage. Optionally, it further includes a drainage port structure maintaining unit, which extends to the edge of the second drainage port with a weaker adhesiveness than the adhesive layer.

[0029] The following describes specific embodiments of the present invention with reference to the drawings, wherein the same or similar components are represented by the same component symbols.

[0030] Figure 1 This is one embodiment of the present invention. The fluid-carrying patch 10 includes a first sheet 11 having at least one first drainage port 12, having a first surface S1 and a second surface S2; a second sheet 21 having a third surface S3 and a fourth surface S4, a portion of the third surface S3 being connected (fused or bonded) to a portion of the second surface S2 of the first sheet 11 at least one strip region 1121, thereby forming a first chamber R1 having at least one opening, which can be used to store fluid. The interior of the first chamber R1 can communicate with the outside through the first drainage port 12. The edges of the first sheet 11 and the edges of the second sheet 21 can be aligned with each other (but are not limited thereto); an adhesive layer 22 is provided on the fourth surface S4 of the second sheet 21 for adhering to the user, so that the fluid-carrying patch 10 is attached to the body surface; a release layer 23 covering at least a portion of the adhesive layer 22 to prevent the adhesive layer 22 from losing its adhesiveness due to contamination before use. The release layer 23 can be, for example, release paper.

[0031] The fluid-carrying patch 10 can be made of, for example, but not limited to, natural latex, synthetic latex, rubber, silicone, polyisoprene (PI), polyurethane (PU), polyethylene (PE), polyvinyl chloride (PVC), polymeric materials, biomaterials, or synthetic biological DNA materials. The adhesive layer 22 may contain, for example, a pressure-sensitive adhesive, allowing the second sheet 21 to adhere to the user's skin via the adhesive layer 22. The second sheet 21 can also be made of an adhesive material. The second surface S2 of the first sheet 11 and the third surface S3 of the second sheet 21 are connected using, for example, but not limited to, solvents, adhesives, tapes, or films, or by melting and bonding by, for example, but not limited to, electrothermal, ultrasonic, or high-frequency methods.

[0032] The first sheet 11 and the second sheet 21 can be soft sheets in their natural state, preferably made of elastic material, but non-elastic material can also be used. Their thickness is preferably no more than 0.1 mm. The first sheet 11 and the second sheet 21 can be manufactured as flat or curved films, and their edge shapes can be, but are not limited to, circular, elliptical, rounded polygonal, or any shape. The first sheet 11 is preferably a waterproof sheet, such as a thermoplastic polyurethane (TPU) film. The second sheet 21 is used to adhere to the user's skin, so it needs to have good breathability. It can be a microporous film, such as, but not limited to, a highly breathable / moisture-permeable polyurethane (PU) film. Its thickness is preferably less than 0.1 mm, more preferably less than 0.05 mm, and most preferably less than 0.03 mm. Its breathability is preferably a water vapor transmission rate (MVTR) greater than or equal to 500 g / (㎡·24h), and its moisture permeability after coating is preferably greater than or equal to 1000 g / (㎡·24h). To improve skin-friendliness and comfort, any material, such as woven material, non-woven material, or film, can be adhered to the first surface S1 of the first sheet 11. For ease of understanding of the sheet structure, most of the following illustrations are presented as cross-sectional views and chambers filled with fluid.

[0033] Figures 2A to 2C This is another embodiment of the present invention. A third sheet 31 is added between the first sheet 11 and the second sheet 21 of the fluid-carrying dressing 10, thereby forming a second cavity R2 between the third sheet 31 and the second sheet 21. The edge of the third sheet 31 can be simultaneously fused / bonded between the first sheet 11 and the second sheet 21 (e.g., Figure 2A (as shown), or fused / bonded to the first sheet 11 (as shown) Figure 2B (as shown), or fused / bonded to the second sheet 21 (as shown) Figure 2C (As shown). The first chamber R1 and the second chamber R2 can be injected with the same or different fluids, respectively.

[0034] Figure 3In another embodiment of the present invention, it can be used for cold / hot compresses. The first drainage port 12 located on the first sheet 11 further includes a drainage portion connected to the first drainage port 12, allowing the interior of the first chamber R1 to communicate with the outside through the first drainage port 12 and the drainage portion. The first drainage port 12 may also be formed by the overlapping and connecting edges of two first sheets 11, with an open portion at the connection point. In this embodiment, the first sheet 11 and the second sheet 21 are thermoplastic films. After heat-sealing along their edges, a strip-shaped region 1121 is continuously and closedly formed at the edges of the first sheet 11 and the second sheet 21. The drainage portion is a drainage tube 13 corresponding to the first drainage port 12, one end of which is connected to the first sheet 11 and communicates with the outside of the first chamber R1 through the first drainage port 12. The drainage tube 13 has an inner cross-section that is approximately the same as or larger than that of the first drainage port 12. It can be configured by connecting the cross-section of one end of the drainage tube 13 to the first surface S1 or the second surface S2 of the first sheet 11, or as follows: Figure 3 As shown, one end of the drainage tube 13 has a cap edge 131 that is substantially perpendicular to the axial direction of the drainage tube 13 and surrounds the periphery of the drainage tube 13 (for example, the two are integrally formed). The cap edge 131 is connected to the first surface S1 of the first sheet 11, thereby improving the tightness and reliability of the connection between the drainage tube 13 and the first sheet 11. The drainage tube 13 may have a closed end, which is integrally formed with the other parts of the drainage tube 13, for example, a test tube. Alternatively, the drainage tube 13 may further include a cap 14 to allow the drainage tube 13 to be opened or closed. In this embodiment, the drainage tube 13 extends from the first drainage port 12 in the opposite direction to the first chamber R1, and the cap 14 and the drainage tube 13 are threaded together to lock into each other. In use, the fluid-carrying patch 10 is adhered to the user's skin via the adhesive layer 22. Then, cold / hot water is injected into the first chamber R1, and the drainage tube 13 is closed with the cover 14. This allows the user to apply ice or heat, receive physical therapy, or keep warm in cold weather. The drainage tube 13 can also be used to drain and replace the water when the temperature approaches body temperature. Those skilled in the art will understand that in this embodiment, the aforementioned thread can be simplified to one of the cover 14 and the drainage tube 13 having a flange and the other having a recess, allowing them to engage with each other.

[0035] Figure 4In another embodiment of the present invention, it can be used to visually enlarge the breasts of women after they wear clothing. The cap 131 of the drainage tube 13 is connected to the second surface S2 of the first sheet 11. The drainage tube 13 extends from the first drainage port 12 toward the first chamber R1 for injecting fluid. After water is injected, when the cover 14 is about to be put on the drainage tube 13, the fluid in the first chamber R1 will be discharged due to pressure or gravity. Therefore, the drainage tube 13 may further include a check structure to prevent fluid from flowing from the inside of the first chamber R1 to the outside through the drainage tube 13. The first chamber R1, which is formed by connecting the first sheet 11 and the second sheet 21 by a continuous closed strip area 1121, especially the first chamber R1 made of soft sheet, will expand from the periphery to the center like a pillow when filled with fluid. The pressure of the fluid will make the edge of the second sheet 21 easily peel off from the body surface. To overcome the aforementioned problems, the edge of the second sheet 21 can be larger than the outer edge of the strip region 1121 or the edge of the first sheet 11, creating a distance between the outer edge of the strip region 1121 and the edge of the second sheet 21. This distance is preferably greater than 3 mm, more preferably greater than 8 mm, and most preferably greater than 15 mm. This allows for better adhesion of the periphery of the fluid-bearing applicator 10, similar to how a tent is secured to the ground with ropes and tent pegs. The radially protruding second sheet 21 (like ropes) can be further secured to the body surface by the adhesive layer 22 (like tent pegs), allowing the side of the first chamber R1 adjacent to the second sheet 21 to adhere more smoothly. Furthermore, using the inner edge of the strip region 1121 as a reference point, the adhesive layer 22 provides a double-sided fixation effect on both the inner and outer sides of the second sheet 21, effectively resisting peeling of the second sheet 21 from the body surface due to excessive tension or hydraulic pressure on the first sheet 11. Furthermore, since the second sheet 21 is larger than the outer edge of the strip region 1121 (i.e., the edge of the second sheet 21 is a distance from the outer edge of the strip region 1121), its total thickness gradually increases from the edge to the center, relative to... Figures 1 to 3The thicker (two-layer) edges of the first sheet 11 and the second sheet 21, which are aligned with each other, are prone to curling due to friction, while the thinner edges are better able to prevent the periphery of the fluid-bearing patch 10 from peeling off due to friction. The invention may also include a structural support unit 91, which extends along the edge of the first sheet 11 or the second sheet 21, acting like a frame on the first sheet 11 or the second sheet 21 to maintain its edge shape before application, preventing wrinkles. The user can remove the structural support unit 91 after application. In this embodiment, the second sheet 21 used to adhere the breast is a planar film, while the first sheet 11 is preferably made of a curved film, thus increasing the capacity of the first cavity R1 and making the breast appear larger. Additionally, a fourth sheet 41 for absorbing sweat can be provided on at least a portion of the adhesive layer 22. The fourth sheet 41 is an absorbent sheet containing fibers, pores, or superabsorbent polymers, such as, but not limited to, facial tissue, cotton, gauze, nonwoven fabric, sponge, or artificial leather, and its edge does not extend beyond the inner edge of the strip region 1121. Besides enlarging the external contour of the breast, other body surface curves, such as, but not limited to, flat feet and arches, can also be modified in the same way.

[0036] Figures 5A to 5E For the application of this invention to visually enlarge the outer contour of a woman's breasts when she wears clothing, the fluid-carrying dressing 10 includes a fifth sheet 51. A portion of the fifth sheet 51 is connected to the second surface S2 of the first sheet 11 and has a liftable portion 52. The liftable portion 52 is larger than the first drainage port 12 and can completely cover the first drainage port 12 from the inside of the first chamber R1. Thus, the liftable portion 52 can only be lifted towards the inside of the first chamber R1, which has the function of a check valve to prevent fluid from flowing from the inside of the first chamber R1 to the outside through the first drainage port 12 (if a portion of the fifth sheet 51 is connected to the first surface S1 of the first sheet 11, it has the opposite effect). Step 1 is as follows. Figure 5A As shown, the release layer 23 is separated and peeled off, exposing the adhesive layer 22 on the second sheet 21. Step 2 is as follows. Figure 5B As shown, the adhesive layer 22 is oriented towards the breast, and the second sheet 21 is adhered to the breast skin. Step 3 (optional) is as follows. Figure 5C As shown, remove the structure-supporting unit 91. Step 4 is as follows. Figure 5D As shown, an appropriate amount of water is injected through the first drainage port 12. The hydraulic pressure within the first chamber R1 pushes the liftable part 52 towards the first drainage port 12 and blocks it. The gradually expanding first chamber R1, with its second sheet 21 pressing against the pectoralis major muscle, compresses the soft tissue of the covered area of ​​the breast, causing the breast to appear concave. Its first sheet 11 then integrates with the skin of the uncovered area of ​​the breast to form the enlarged breast contour. Step 5 is as follows... Figure 5EAs shown, the first drainage port 12 is then covered with a cover 14 equipped with reusable adhesive to prevent a small amount of fluid from leaking out. The water in the first chamber R1 can be integrated with the user's breasts through the above steps to create a natural body surface curve. Women can also easily adjust the volume of their breasts by adjusting the amount of water injected. Since the specific gravity of water is close to that of the human body, its fluid properties can better reproduce the drooping feeling and touch of the breasts.

[0037] One embodiment of the present invention, for example Figure 6A As shown, a portion of the first sheet 11 extends outward to form an extension 111. The extension 111 is folded back and its edge is connected to the first sheet 11 to form a fastening strap. One embodiment of the invention is, for example... Figure 6B As shown, the first sheet 11 or the second sheet 21 has a wavy edge, making the fluid-carrying patch 10 more suitable for adhering to non-planar surfaces. The wavy edge of the second sheet 21 also provides claw-like grip, making it more resistant to pulling when the bag is filled with fluid. A fastener 92 can be further provided on the edge of the first sheet 11 or the second sheet 21 to permanently or detachably connect two adjacent fluid-carrying patches 10. The fastener 92 can be, for example, but not limited to, a loop, button, rivet / buckle, hook and loop, zipper, tape, Velcro, or strap / cord. In this embodiment, the fastener 92 is a C-shaped / U-shaped loop, with both ends of the loop passing through two opposing straps formed by the extensions 111 of the first sheet 11, thereby reducing the distance between the breasts and making the woman's breasts appear more concentrated and the cleavage more prominent.

[0038] Figures 7A to 7G In another embodiment of the present invention having two first drainage ports 12, the second sheet 21 is always made of the same cut piece, and its petal-shaped edges are similar to those of the first sheet. Figure 6B The wavy edges have the same effect, making the second sheet 21 more suitable for adhering to non-planar surfaces. A check valve structure is formed by die-cutting a C-shaped / U-shaped first liftable portion 112 from the first sheet 11, which forms part of the first drainage port 12A. A sixth sheet 61 is further provided in the first drainage port 12A, the edge of which is closedly connected to the first surface S1 of the first sheet 11 around the first liftable portion 112 and has an opening smaller than the first liftable portion 112 and can be completely blocked by the first liftable portion 112 from the inside of the first chamber R1, so that the first liftable portion 112 can only be lifted towards the inside of the first chamber R1. It has the function of a check valve to prevent the fluid injected by the user from flowing from the inside of the first chamber R1 to the outside through the first drainage port 12A (if the edge of the sixth sheet 61 is connected to the second surface S2 of the first sheet 11, it will have a reverse effect). Figure 7AAs shown, the second surface S2 of the first sheet 11 and the third surface S3 adjacent to the edge of the second sheet 21, where they are not fused or bonded together, have an open portion, forming another first drain port 12B. When a check valve structure (not shown in the figure) is provided in the first drain port 12B, a first liftable portion 112 can be formed at the edge of the first sheet 11 adjacent to the first drain port 12B. The edge of the sixth sheet 61 is closed and connected to both the first sheet 11 and the second sheet 21 in a manner surrounding the first liftable portion 112. The first drain port 12B may further include a drain section. In this embodiment, the drain section is a drain tube 13, which is sandwiched between the first sheet 11 and the second sheet 21. An extension tube 93 can be further connected to the drainage tube 13 for drainage purposes. The fluid in the first chamber R1 can be discharged into the user's mouth through the first drainage port 12B, the drainage tube 13, and the extension tube 93, serving as a water bottle that can be attached to the body for outdoor activities such as long-distance running, cycling, long-distance swimming, or diving, allowing for replenishment of water or liquid food at any time during the activity. Alternatively, the first chamber R1 can be made into a flow space with water entering at one end and exiting at the other end. When the invention is used for cold / hot compress, water at the same temperature can be continuously injected to keep the first chamber R1 at a constant temperature. In addition to being coated with adhesive during the manufacturing process, the adhesive layer 22 may also include materials such as double-sided tape, with one side adhering to the second sheet 21 and the other side adhering to the user. The first chamber R1, formed by connecting the first sheet 11 and the second sheet 21 to each other, can be reused by simply replacing the double-sided tape. Figure 7B This is a front view. The drainage tube 13 is formed by combining the two sides of two seventh sheets 71. The first drainage port 12B surrounds the drainage tube 13. The seventh sheets 71 adjacent to the first drainage port 12B are respectively closedly connected to the second surface S2 of the first sheet 11 and the third surface S3 of the second sheet 21 (e.g., Figure 7C As shown), this makes the drainage tube 13 flat in its natural state. Using a thin film material with a thickness of less than 0.1 mm to manufacture the drainage tube 13 provides a backflow prevention function, preventing fluid from flowing out of the first chamber R1. One of the opposing surfaces of the drainage tube 13 is provided with an insulating material 94 (not shown in the figure) to prevent the inner surfaces of the seventh sheet 71 (excluding the two sides) from obstructing fluid flow due to heat fusion during manufacturing. The insulating material 94 is applied by clamping, coating, or printing before the two sheets are joined to form the drainage tube 13. An insulating material 94 (e.g., ...) is provided on the seventh sheet 71 adjacent to the second sheet 21. Figure 7D As shown), in this embodiment, the first sheet 11 may further include an extension 111, which replaces the seventh sheet 71 originally connected to the first sheet 11 (i.e., the first sheet 11 and the seventh sheet 71 are integrally formed) and forms a drainage tube 13. Figure 7E This is a front view; the drainage section is a drainage bag 16 provided corresponding to the first drainage port 12B, and... Figure 7B Similar to the drainage tube 13, the drainage bag 16 is also formed by combining the two sides of two seventh sheets 71 and simultaneously combining them with the bottom edge. Further widening and lengthening the seventh sheets 71 can increase the capacity of the drainage bag 16. For example... Figure 7F As shown, the drainage bag 16 is like Figure 7D The drainage tube 13 in the middle, the seventh sheet 71 adjacent to the first sheet 11 can be replaced by an extension of the first sheet 11. The end of the extension 111 of the first sheet 11 is connected to the bottom edge of the seventh sheet 71, and the top edge of the seventh sheet 71 is connected to the second sheet 21. Combining the extension 111 and the open sides of the seventh sheet 71, a drainage bag 16 is formed. An isolation material 94 is provided on one of the surfaces of the seventh sheet 71 and the extension 111. Then, a cover 14 with reusable adhesive is used to cover the opening of the sixth sheet 61 to prevent a small amount of fluid from seeping out. Figure 7G As shown, the drainage bag 16 is formed by folding an eighth sheet 81 in half and closing all or part of its edges. In this embodiment, a drainage tube 13 is further provided corresponding to the opening of the sixth sheet 61.

[0039] Figures 8A to 8C In another embodiment of the present invention, an open portion at the adjacent edges of the first sheet 11 and the second sheet 21 that is not connected to each other forms a first drainage port 12. For example... Figure 8A As shown, the extension 111 of the first sheet 11 is further replaced Figure 7GThe eighth sheet 81, folded in half, forms a drainage bag 16. The drainage bag 16 is formed by connecting the first surface S1 of the extended first sheet 11 with the third surface S3 of the second sheet 21, and combining the two open sides of the extension 111 after folding. At the same time, the second sheet 21 has at least one second drainage port 24, so that the interior of the first chamber R1 can communicate with the exterior of the first chamber R1 through the second drainage port 24. The second drainage port 24 is smaller than the inner edge of the strip region 1121, so that there is a distance between the second drainage port 24 and the inner edge of the strip region 1121. This distance is preferably greater than 3 mm, more preferably greater than 8 mm, and most preferably greater than 15 mm. When this invention is used as a semen collection device, the thickness of the first sheet 11, the second sheet 21, and the seventh sheet 71 is preferably less than 0.05 mm, more preferably less than 0.03 mm, and most preferably less than 0.02 mm; the circumference of the second sheet 21 is preferably less than 180 mm, more preferably less than 150 mm, and most preferably less than 120 mm; the widest point of the second sheet 21 is preferably less than 60 mm, more preferably less than 55 mm, and most preferably less than 50 mm; and the volume of the drainage bag 16 is preferably less than 20 ml, more preferably less than 15 ml, and most preferably less than 10 ml. The smaller circumference and thickness allow for a thinner and shorter fluid-carrying dressing 10, enhancing pleasure for both partners during sexual intercourse; the volume is set to accommodate a male ejaculation volume that typically does not exceed 10 ml. Figure 8B The image shows another embodiment of the present invention for collecting semen. Since the glans penis near the frenulum in men bears the greatest frictional force during sexual intercourse, the first sheet 11 and the second sheet 21 located in this area are connected to each other in a U-shaped / C-shaped strip area 1121. During sexual intercourse, the first chamber R1 is approximately sealed, effectively preventing frictional forces from pulling on the first sheet 11 and the second sheet 21 and causing them to peel off. Figure 8C This is the rear view (please also refer to...) Figure 8A The second drainage port 24 extends from the center of the second sheet 21 to the upper edge of the second sheet 21, forming a second sheet 21 with an open upper end in a U-shape (or C-shape / V-shape). In use, the open end is facing the pubic bone of the bedridden woman, and the fluid-carrying dressing 10 is adhered to the vulva to directly collect urine samples without the need for invasive catheterization. The open end design of the second sheet 21 avoids the difficulty of removal due to body hair adhering to the adhesive layer 22. The structural support unit 91 (not shown in the figure) can also extend outward from the edge to form a pinching part 911 protruding from the second sheet 21. At least one point of the pinching part 911 is connected to the structural support unit 91 for the user to pinch with their fingers, which facilitates the adjustment of the position of the invention before application or the removal of the structural support unit 91 after application.

[0040] Figures 9A to 9C This is another embodiment of the present invention. For example... Figure 9AAs shown, the drainage tube 13 has a wide tube wall cross-section and an outer cross-section approximately the same as the first drainage port 12. The tube wall cross-section of the cover 14 or one end of the drainage tube 13 is provided with reusable adhesive, allowing the cover 14 to be removably bonded to the drainage tube 13. Simultaneously, the second sheet 21 has at least one second drainage port 24. The user injects medication or skincare products through the drainage tube 13, allowing the fluid in the first chamber R1 to directly contact the skin surface through the second drainage port 24, directly introducing the medication or skincare product into the wound or soaking the skin. This also prevents medication loss or staining of clothing for transdermal absorption medications. If it is necessary to slow the effect of the fluid on the skin surface, a one-way or two-way permeable membrane (such as...) can be provided at the second drainage port 24. Figure 9B As shown), for example, gauze, meltblown nonwoven fabric, or at least a portion of the second sheet 21 is processed to form a plurality of second drainage ports 24, tiny and densely arranged openings that allow fluid to slowly permeate through the microporous membrane. Optionally, when the user injects fluid, the hinged portion 52 of the fifth sheet 51 can prevent fluid from flowing out. A plurality of dotted / strip-shaped areas 1121 (e.g., ...) can also be further added within the first chamber R1. Figure 9C As shown, it is Figure 9B (Front view), so that a plurality of small chambers with mutual circulation are formed inside the first chamber R1, and the distance between the first sheet 11 and the second sheet 21 is small (e.g., Figure 9B As shown, it can achieve the best wetting effect with less fluid. The two sides of the structure holding unit 91 can be further provided with pinching parts 911 for easy operation by the user.

[0041] Figure 10 This is another embodiment of the present invention. The second sheet 21 has a second drainage port 24, and the drainage portion is a drainage bag 16 provided corresponding to the first drainage port 12, which can be used as follows: Figure 7E The second drainage bag 16 is formed by combining the second seventh sheet 71, or as shown in this embodiment, by folding an eighth sheet 81 in half and closing all or part of its edges, with an open portion forming a drainage port. In use, the second drainage port 24 is aligned with the female urethral opening and vaginal opening, and the second sheet 21 is adhered to the vulvar skin via the adhesive layer 22. The user's urine or menstrual blood can be drained into the drainage bag 16 for storage. The drainage bag 16 can also be further connected to a second drainage tube 95, allowing bodily fluids to drain out as needed. Furthermore, the drainage bag 16 in this embodiment may further include a structure with a backflow prevention function to prevent fluid in the drainage bag 16 from flowing back into the first chamber R1. Figure 10As shown, the first sheet 11 has a first liftable portion 112, and the eighth sheet 81 constituting the drainage bag 16 has a second liftable portion 96 larger than the first liftable portion 112. The first sheet 11 and the eighth sheet 81 are connected in a closed manner around the first liftable portion 112 and the second liftable portion 96, and at least a portion of the first liftable portion 112 is connected (welded or bonded) to the second liftable portion 96. Since the size of the first liftable portion 112 is smaller than that of the second liftable portion 96, after the two are connected, they can only be lifted towards the inside of the drainage bag 16, thus preventing the backflow of fluid in the drainage bag 16. Those skilled in the art will understand that if the drainage bag 16 is composed of two seventh sheets 71, the second liftable portion 96 can also be provided on the seventh sheet 71 to prevent backflow of fluid.

[0042] Figure 11 This is another embodiment of the invention. A flat, force-applying part 132 can be further provided on the drainage tube 13, facilitating the opening or closing of the drainage tube 13 by holding the drainage tube 13 with one hand and operating the cover 14 with the other. In use, first separate and peel off the release layer 23, then align the second drainage port 24 with the woman's nipple and adhere the second sheet 21 to the breast skin via the adhesive layer 22. Next, insert the cover 14 using the material's elasticity and friction to close the drainage tube 13. The user's milk can flow through the second drainage port 24 into the first chamber R1 and be stored. Afterwards, open the drainage tube 13 at a suitable location to drain the milk. This invention can help breastfeeding mothers avoid milk leakage staining their clothes or causing odors. When the second sheet 21 is adhered to a curved, irregularly undulating, or obese body surface, the edge of its second drainage port 24 is prone to wrinkling. This is because the hydraulic force causes fluid to seep out from the tiny channels formed at the wrinkles toward the edge of the second sheet 21, eventually causing the second sheet 21 to peel off as the adhesive layer 22 gradually loses its adhesiveness. Therefore, a drainage port structure support unit 25 can be further provided on the third surface S3 of the second sheet 21, around the edge of the second drainage port 24, to maintain the shape of the second drainage port 24 and prevent leakage. The drainage port structure maintaining unit 25 can be adjusted by adjusting the adhesion (for example, making the adhesion between the drainage port structure maintaining unit 25 and the second sheet 21 less than the adhesion of the second sheet 21 to the human body through the adhesive layer 22). After the second sheet 21 is adhered to the body surface, when the body surface wrinkles due to compression or friction, the drainage port structure maintaining unit 25 will peel off from the second sheet 21 due to its weak adhesion, without affecting the fit between the edge of the second drainage port 24 and the body surface.

[0043] Figure 12A and Figure 12B The embodiment of the invention shown is for breastfeeding and includes a removable fluid-carrying dressing 10 with, but not limited to, an extension tube, drainage bag, nipple, or valve. Please refer to... Figure 12AThe second sheet 21 has a second drainage port 24, and the drainage tube 13 has a larger inner cross-section than the first drainage port 12, giving the first chamber R1 a better sealing and leak-proof effect. Furthermore, the cover 14 can be further connected to a second drainage bag 97, which is provided corresponding to a cover drainage port 141 on the cover 14. Thus, when the cover 14 is locked to the drainage tube 13, the interior of the first chamber R1 can communicate with the interior of the second drainage bag 97 through the first drainage port 12, the drainage tube 13, and the cover drainage port 141, which can help breastfeeding mothers express and store milk. Those skilled in the art will understand that in this embodiment, a second drainage bag 97 can also be directly connected to the drainage tube 13 to store bodily fluids. Figure 12B As shown, a nipple 98 can also be clamped between the drainage tube 13 and the cap 14 to avoid nipple pain and damage caused by breastfeeding. In this embodiment, the cap 14 can also be further connected to a valve, lid, switch, or sticker to facilitate opening or closing the drainage port 141 to discharge milk and prevent spillage onto clothing, or further connected to an extension tube 93 to drain the milk to a distant container. The cap rim 131 at one end of the drainage tube 13 can be configured in ways such as, but not limited to, having a flange on one side and a recess on the other, so that they interlock (e.g., ...). Figure 12B (As shown), the two are locked together by threads, connected by integral molding, or one of the cap edge 131 and the drainage tube 13 is inserted into the other by means of material elasticity and friction.

[0044] Figure 13 This is another embodiment of the present invention. Please also refer to... Figure 12B In addition to a drainage tube 13 including a detachable nipple 98 and a cover 14, the first sheet 11 can also have another drainage tube 13 for injecting cow's milk, helping mothers with low milk production. The second sheet 21 can have a second drainage port 24, allowing milk secreted from the nipple to flow into the first chamber R1 simultaneously; the second sheet 21 can also be a continuously closed sheet, allowing users without breast milk (such as fathers) to feed their babies.

[0045] Figure 14 This is another embodiment of the present invention. Please also refer to... Figure 2C and Figure 5AIn addition to the liftable portion 52 that covers the first drainage port 12A, the fluid-carrying patch 10 further includes a third sheet 31 disposed between the first sheet 11 and the second sheet 21, with its edge fused / bonded to the second sheet 21, thereby forming a second chamber R2 (separated from the original first chamber R1) between the third sheet 31 and the second sheet 21. The third surface S3 of the second sheet 21 and the part of the edge of the third sheet 31 that is not fused or bonded to each other form an open portion, which is further connected to a second drainage tube 95, which is sandwiched between the second sheet 21 and the third sheet 31 and passes through another first drainage port 12B, so that the interior of the second chamber R2 can communicate with the outside through the second drainage tube 95. In use, the user first adheres the fluid-carrying patch 10 to the breast, then injects air into the second chamber R2 through the second drainage tube 95, and then injects water into the first chamber R1 through the first drainage port 12A. This not only visually enlarges the breast when the user is wearing clothing, but also reduces the burden on the chest. Those skilled in the art will understand that the second drainage tube 95 can also be connected to a second drainage port 24 (not shown) on the second sheet 21. In this embodiment, the second sheet 21 used to adhere to the breast is a planar film, the third sheet 31 can be manufactured as a planar or curved film, and the first sheet 11 is preferably manufactured as a curved film.

[0046] Figure 15A and Figure 15B This is another embodiment of the present invention. Please also refer to... Figures 7E to 7G , Figure 8A and Figure 10 ,like Figure 15A As shown (it is) Figure 7E In the rear view, the second sheet 21 is further processed to form a second drainage port 24. One embodiment of the fluid-carrying dressing 10 of the present invention further includes a loop 161 on the drainage bag 16, allowing a fixing rope or strap to pass through the loop channel formed between the loop 161 and the drainage bag 16, thus securing the drainage bag 16 to a part of the user's body. To allow the user to choose different fixing positions, a plurality of loops 161 can be provided on the drainage bag 16. Figure 15A As shown, when the drainage bag 16 is positioned approximately parallel to the leg, a plurality of loops 161 can be arranged vertically. This not only improves the stability of securing the drainage bag 16 but also allows the user to select loop channels at different positions to adjust for optimal fixation. The loops 161 can be formed, for example, by using a loop sheet 162, which is then welded or bonded (but not limited to) to the drainage bag 16. For example, as... Figure 15A As shown, when the loop sheet 162 is rectangular, it can be combined with the drainage bag 16 at opposite sides of the rectangle, or at two or more points within the rectangle. Or as... Figure 15B As shown, a long strip of loop material 162 is used, and this long strip of loop material 162 is attached to the drainage bag 16 at three or more positions along its long side to form a plurality of loop channels. A fastening hole 163 can be further processed on the loop material 162 at the position corresponding to each loop channel, which, together with the fastener on the fixing strap, can prevent the drainage bag 16 from sliding along the direction of the fixing rope or fixing strap.

[0047] Figure 16 This is another embodiment of the invention. The fluid-carrying patch 10 further includes a pulse section 99, which can massage the breast through pulse vibration to unclog mammary glands and promote milk secretion. The pulse section 99 is preferably disposed on the first sheet 11 and can be connected, for example, to the cover 14, particularly the cover 14 provided with reusable adhesive (see reference). Figure 5E and Figure 9A The pulse unit 99 may have a vibration device or a discharge device, which is disposed on the first sheet 11 and further utilizes the good conductivity of the fluid in the first chamber R1 to make the pulse vibration or pulse current more effectively and evenly conducted to the body surface covered by the second sheet 21 or the second drainage port 24, so that the pulse vibration can have a better massage effect, or the pulse current can have a better electrotherapy effect, or promote the absorption of drugs or skin care products in the first chamber R1 by the body surface.
