Description

Technology Field

[0001] The present invention relates to adult panty diapers, and more specifically, to a functional adult panty diaper capable of absorbing a large amount of body fluids, reducing skin irritation, and maintaining a comfortable state even when worn for a long time. Background Technology

[0002] Generally, urinary incontinence refers to the involuntary leakage of urine through the urethra, while fecal incontinence refers to the leakage of stool through the anus.

[0003] When such urinary or fecal incontinence occurs, the underwear becomes wet with urine or feces. When the wet underwear comes into contact with the skin, it causes discomfort, lowers self-confidence and motivation for life, and further leads to depression or social avoidance. In addition, bacteria and odors caused by persistent moisture can result in restrictions on social activities or the infection of other diseases.

[0004] Due to these problems, adult panty diapers for people with urinary or fecal incontinence have recently been developed and are being used.

[0005] Adult panty diapers consist of a waterproof outer layer shaped like panties and providing waterproofing, a permeable inner layer installed inside the waterproof outer layer that allows body fluids to pass through, and an absorbent layer positioned between the permeable inner layer and the waterproof outer layer to absorb body fluids that have passed through the permeable inner layer; the absorbent layer is made of cotton pulp extracted from wood. Because these panty diapers are designed to be put on and taken off by the wearer like regular underwear and are manufactured as disposable items to be discarded after use, they are widely used by many patients suffering from urinary or fecal incontinence.

[0006] However, in adult panty diapers, the absorbent layer made of cotton pulp can only hold a small amount of body fluid, so they had to be changed frequently when the amount of fluid was large, and the absorbed fluid often leaked out and soiled the clothes.

[0007] In addition, wearing panty diapers for a long time while going about daily life, such as work or travel, caused various skin conditions, such as skin rashes or eczema, to develop due to bodily fluids. The problem to be solved

[0008] The present invention was created to solve the above-mentioned problems and aims to provide a functional adult panty diaper that can be worn for a long time by increasing the amount of body fluid that can be absorbed.

[0009] Another objective of the present invention is to provide a functional adult panty diaper that can prevent odors from developing or skin irritation even when worn for a long time, and allows the time for replacement to be visually checked. means of solving the problem

[0010] To achieve the above objectives, the functional adult panty diaper according to the present invention comprises: a waterproof outer layer (10) that forms a panty shape and has a waterproof function, which is fitted with both legs and wraps around the buttocks when worn; a permeable inner layer (20) that is installed inside the waterproof outer layer (10) and adheres to the front and rear sides of the lower body and has a body fluid permeability function; an absorbent layer (30) that is positioned between the permeable inner layer (20) and the waterproof outer layer (10) and absorbs body fluid that has permeated through the permeable inner layer (20); leak-proof wings (40) that are connected to both sides of the permeable outer layer (20) inside the waterproof outer layer (10) and adhere to the wearer's thighs and groin, and are made of an elastic material to prevent body fluid from leaking; and an elastic band (50) that is elastic and is connected to the upper side of the waterproof panty (10) and wraps around the waist.

[0011] In the present invention, a diamond-shaped quilting pattern (21)(31) is formed on the permeable inner layer (20) and the absorbent layer (30).

[0012] In the present invention, a waterproof pocket (60) is further included, which is formed to partially overlap the upper side of the absorbent layer (30) while covering the bottom surface of the absorbent layer (30) facing the waterproof outer shell (10).

[0013] In the present invention, the waterproof pocket (60) facing the absorption layer (30) is coated with an indicator (80) that changes color when reacting with an alkaline substance.

[0014] In the present invention, an alkali neutralization layer (70) is further included, which is formed on the surface of a permeable inner lining (20) that is in close contact with the absorption layer (30) and is for neutralizing the ammonia component of an alkaline body fluid.

[0015] In the present invention, the alkali neutralization layer (70) comprises a net binder layer (71) coated on the surface of the permeable inner skin (20), and a weakly acidic microcapsule (72) attached to the net binder layer (71) that dissolves when it comes into contact with body fluid. Effects of the invention

[0016] According to the present invention, by including a permeable inner liner (20) installed on the inner side of a waterproof outer liner (10) and adhering to the buttocks and groin side, an absorbent layer (30) that absorbs body fluids that have passed through the permeable inner liner (20), leak-prevention wings (40) connected to both sides of the permeable outer liner (20) and adhering to the wearer's thighs and groin side, and an elastic band (50) connected to the upper side of the waterproof panty (10), the panty diaper can be used while adhering to the body without a strong feeling of pressure during long-term wear, and can prevent body fluids generated from the body from leaking to the legs.

[0017] In addition, by employing a waterproof pocket (60) that wraps around the bottom surface of the absorbent layer (30) and is partially overlapped on the upper side of the absorbent layer (30), it is possible to prevent body fluid remaining that is not absorbed into the absorbent layer (30) from flowing back to the permeable inner lining (20).

[0018] In addition, by employing an alkali neutralization layer (70) formed on the surface of a permeable inner lining (20) that adheres to an absorbent layer (30), alkaline ammonia generated from the body fluids of the wearer can be neutralized, thereby preventing unpleasant odors from occurring or the skin from becoming sore, and thus maintaining a comfortable state.

[0019] In addition, by employing an indicator (80) coated on the waterproof pocket (60), body fluid that has not been absorbed in the absorbent layer (30) and has moved to the waterproof pocket (60) can be detected by a color change, and the maximum replacement time of the adult diaper can be visually indicated by the color change of the indicator (80).

Specific details for implementing the invention

[0021] Hereinafter, a functional adult panty diaper according to the present invention will be described in detail with reference to the attached drawings.

[0022] In the following, terms described as "upper" or "upper" may include not only those directly above in contact but also those above without contact. Terms such as "first," "second," etc., may be used to describe various components, but the components should not be limited by these terms. Terms are used solely for the purpose of distinguishing one component from another. A singular expression includes a plural expression unless the context clearly indicates otherwise. Furthermore, when a part is described as "comprising" a component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components. Additionally, terms such as "...part," "module," etc., as used in the specification refer to a unit that performs at least one function or operation. Where an embodiment can be implemented differently, a specific process sequence may be performed differently from the order described. For example, two processes described consecutively may be performed substantially simultaneously or proceed in the reverse order of description.

[0023] FIG. 1 is a front view of a functional adult panty diaper according to the present invention, and FIG. 2 is a drawing for explaining the configuration of the panty diaper of FIG. 1 unfolded. Also, FIG. 3 is a drawing for explaining that a two-beam pattern is formed on the transparent inner lining of FIG. 2, and FIG. 4 is a drawing for explaining that a leak-proof wing is connected to the edge of the transparent inner lining of FIG. 2.

[0024] The functional adult panty diaper according to the present invention is characterized by comprising: a waterproof outer layer (10) that forms a panty shape and has a waterproof function, which is fitted with both legs and wraps around the buttocks when worn; a permeable inner layer (20) that is installed inside the waterproof outer layer (10) and adheres to the front and rear sides of the lower body and has a body fluid permeability function; an absorbent layer (30) that is positioned between the permeable inner layer (20) and the waterproof outer layer (10) and absorbs body fluid that has permeated through the permeable inner layer (20); leak-preventing wings (40) that are connected to both sides of the permeable outer layer (20) inside the waterproof outer layer (10) and adhere to the wearer's thighs and groin, and are made of an elastic material to prevent body fluid from leaking; and an elastic band (50) that is connected to the upper side of the waterproof panty (10) and wraps around the waist and is elastic.

[0025] The waterproof outer shell (10) is made of a plastic film that does not allow water to pass through, such as polyethylene, and has a waterproof function that prevents body fluids absorbed in the absorbent layer (30), such as urine or feces, from leaking out. At this time, it is desirable that the waterproof outer shell (10) has a number of breathable air holes formed therein to release moisture from the body fluids and allow external air to pass through, thereby preventing skin irritation.

[0026] The permeable inner layer (20) allows body fluids to pass through so that the absorbent layer (30) can absorb them. It is made of a soft non-woven fabric material to reduce friction with the skin that is in close contact and to alleviate skin irritation.

[0027] The absorbent layer (30) is positioned in the form of a pad between the permeable inner layer (20) and the waterproof outer layer (10) and absorbs body fluid that has passed through the permeable inner layer (20). The absorbent layer (30) is implemented by processing natural pulp extracted from wood into a cotton-like form and functions to rapidly absorb body fluid that has passed through the permeable inner layer (20) and simultaneously spread it across the entire surface.

[0028] As shown in FIG. 3, a diamond-shaped quilting pattern (21)(31) is formed on the permeable inner layer (20) and the absorbent layer (30). The quilting pattern (21)(31) presses the permeable inner layer (20) and the absorbent layer (30) into a diamond shape, thereby keeping the laminated structure of the permeable inner layer (20) and the absorbent layer (30) slim and preventing the absorbent layer (30) from swelling excessively when absorbing body fluids.

[0029] As shown in FIG. 4, the leak-proof wing (40) is implemented as a double-structure elastic band connected to both sides of the permeable pad (20) and wrapped around the thigh and groin area. The leak-proof wing (40) prevents bodily fluids from leaking sideways even when the wearer is moving a lot or lying down while wearing the panty diaper.

[0030] FIG. 5 is a drawing for explaining the structure by extracting the elastic band of FIG. 1, and FIG. 6 is a drawing for explaining that the elastic band of FIG. 5 is greatly stretched.

[0031] The elastic band (50) is connected to the upper side of the waterproof outer shell (10) and is formed to wrap around the entire abdomen and waist. The elastic band (50) includes a folding section (51) that is folded in a zigzag pattern in the vertical direction and a plurality of elastic threads (52) that connect the folding section (51) in the horizontal direction. The plurality of elastic threads (52) are sewn at regular intervals along the folding section (51) in the horizontal direction, and as a result, the elastic band (50) becomes very elastic, allowing it to adhere closely to the body without significant pressure, while simultaneously preventing the elastic band from breaking.

[0032] Side perforations (53) that separate when pulled are formed on both sides of the elastic band (50). The side perforations (53) allow the elastic band (50) to be separated as needed, so that the panty diaper can be removed from the body without taking it off. When the elastic band (50) is separated by these side perforations (53), the used panty diaper can be rolled up and disposed of.

[0033] FIG. 7 is a diagram illustrating the cross-sectional structure of the permeable endothelium and the absorbent layer of FIG. 2, FIG. 8 is a diagram illustrating the absorption of body fluid into the absorbent layer of FIG. 7, FIG. 9 is a diagram illustrating the cross-section of the absorbent layer of FIG. 8, and FIG. 10 is a plan view illustrating the configuration of the indicator of FIG. 7.

[0034] The absorbent layer (30) includes a polymer absorbent capsule (32, SAP (Super Absorbent Polymer)) embedded and dispersed therein, as shown in FIG. 7. The polymer absorbent capsule (32) is made of sodium polyacrylate, which is produced by polymerizing acrylic acid and caustic soda, and has a network structure and can absorb moisture amounting to hundreds of times its own weight. When this polymer absorbent capsule (32) absorbs body fluid, it transforms into a soft jelly-like form and, as shown in FIG. 8 and FIG. 9, serves to tightly trap body fluid so that it does not leak out even when pressure is applied.

[0035] The adult panty diaper of the present invention further includes a waterproof pocket (60) formed to partially overlap the upper side of the absorbent layer (30) while covering the bottom surface of the absorbent layer (30) facing the waterproof outer layer (10).

[0036] The waterproof pocket (60) wraps around the bottom surface of the absorbent layer (30) facing the waterproof outer layer (10) and partially overlaps the upper side of the absorbent layer (30) on the lower surface of the permeable inner layer (20). Accordingly, even if a body fluid exceeding the maximum absorbable amount flows into the absorbent layer (30), the waterproof pocket (60) partially accommodates the body fluid, thereby preventing the body fluid from flowing back toward the permeable inner layer (20).

[0037] The adult panty diaper of the present invention may further include an indicator (80) that changes color when reacting with an alkaline substance, which is coated on a waterproof pocket (60) facing the absorbent layer (30).

[0038] The indicator (80) is normally colorless, but changes color when it reacts with an alkaline body fluid such as urine, and the replacement cycle of the panty diaper can be visually checked according to the color change of the indicator.

[0039] Meanwhile, the indicator (80) includes a first color-changing portion (81) coated on the waterproof pocket (60) and a second color-changing portion (82) formed on the inner side of the first color-changing portion (81) that changes color when a larger amount of body fluid comes into contact with it than the first color-changing portion (81).

[0040] The first color change part (81) is implemented by coating an indicator that reacts to alkaline body fluids, such as Bromophenol Blue, and the second color change part (82) is implemented by mixing an acidic buffer with a Phenolphthalein indicator.

[0041] Due to this structure, when an alkaline body fluid such as urine comes into contact with the first and second color-changing parts (81) (82) simultaneously, the bromphenol blue in the first color-changing part (81) changes to a vivid blue as the pH increases, but in the second color-changing part (82), there is no color change as it is neutralized by an acidic buffer.

[0042] However, if the amount of body fluid increases beyond what can be accommodated in the absorption layer (30), the acidic buffer is completely neutralized and no more amount remains to be neutralized, and in this case, the phenolphthalein reagent takes on a vivid pink color.

[0043] That is, when the amount of body fluid received in the absorbent layer (30) is appropriate, the bromphenol blue reagent reacts and the first discolored part (81) turns blue, and when the amount of body fluid is excessively large, the phenolphthalein reagent reacts and turns a vivid pink color, so by visually confirming this color difference, it is possible to know more clearly whether the panty diaper needs to be replaced.

[0044] In this way, the indicator (80) can detect body fluid that has moved to the waterproof pocket (60) because the absorbent layer (30) has not completely absorbed it, and the maximum replacement time for the adult diaper can be visually known through the color change of the indicator (80).

[0045] FIG. 11 is a diagram illustrating an alkali neutralization layer formed on the surface of a permeable endothelium, and FIG. 12 is a diagram illustrating the structure of the microcapsule of FIG. 10.

[0046] The functional adult panty diaper of the present invention further includes an alkali neutralization layer (70) formed on the surface of a permeable inner liner (20) that adheres to an absorbent layer (30) to neutralize the ammonia component of an alkaline body fluid.

[0047] The alkali neutralization layer (70) includes a mesh binder layer (71) coated on the surface of the permeable inner skin (20), and a microcapsule (72) attached to the mesh binder layer (71) that is weakly acidic, for example, has a pH in the range of 4.5 to 5.5, and dissolves when it comes into contact with body fluid.

[0048] The net binder layer (71) is formed of a water-based binder in a net shape, and forms countless paths so that the body fluid that has passed through the permeable inner layer (20) can move to the absorption layer (30) while adhering the microcapsules (72) to the surface of the permeable inner layer (20).

[0049] The microcapsule (72) has a diameter of 10 to 50 μm (micrometers), preferably 30 μm, so as not to interfere with the soft tactile sensation of the permeable endothelium (20). The microcapsule (72) is composed of a porous capsule body (72a) made of a biodegradable polymer material that dissolves when exposed to urine, and an acid receptor (72b) that is contained in the pores of the capsule body (72a) to neutralize ammonia.

[0050] The capsule body (72a) is implemented in the form of a porous capsule made of a biodegradable polymer, such as a hydrophilic polymer like gelatin, gum arabic, or cyclodextrin. When this capsule body (72a) comes into contact with body fluid, it slowly dissolves and slowly releases the received acidic receptor.

[0051] The acid receptor (72b) is one of the following: citric acid, which neutralizes ammonia in body fluids such as urine without causing skin irritation; lactic acid, which is one of the natural moisturizing factors (NMF) of our skin and has excellent pH regulating ability and skin barrier strengthening effect; or ascorbic acid (vitamin C), which has a neutralizing effect and an antioxidant effect, thereby helping with skin health.

[0052] A sustained-release structure that allows the acidic receptor to be released slowly can be implemented by the above microcapsule (72).

[0053] With this alkali neutralization layer (70), the alkali neutralization process can be carried out over a long period of time while wearing the panty diaper, and accordingly, even if the panty diaper is worn for a long time, it is possible to maintain a comfortable state by preventing the occurrence of odors or skin irritation caused by bodily fluids such as urine.

[0054] Thus, according to the present invention, by including a permeable inner liner (20) installed on the inner side of a waterproof outer liner (10) and adhering to the buttocks and groin side, an absorbent layer (30) that absorbs body fluids that have passed through the permeable inner liner (20), leak-prevention wings (40) connected to both sides of the permeable outer liner (20) and adhering to the wearer's thighs and groin side, and an elastic band (50) connected to the upper side of the waterproof panty (10), the panty diaper can be used while adhering to the body without a strong feeling of pressure during long-term wear, and can prevent body fluids generated from the body from leaking to the legs.

[0055] In addition, by employing a waterproof pocket (60) that wraps around the bottom surface of the absorbent layer (30) and is partially overlapped on the upper side of the absorbent layer (30), it is possible to prevent body fluid remaining that is not absorbed into the absorbent layer (30) from flowing back to the permeable inner lining (20).

[0056] In addition, by employing an alkali neutralization layer (70) formed on the surface of a permeable inner lining (20) that adheres to an absorbent layer (30), alkaline ammonia generated from the body fluids of the wearer can be neutralized, thereby preventing unpleasant odors from occurring or the skin from becoming sore, and thus maintaining a comfortable state.

[0057] In addition, by employing an indicator (80) coated on the waterproof pocket (60), body fluid that has not been absorbed in the absorbent layer (30) and has moved to the waterproof pocket (60) can be detected by a color change, and the maximum replacement time of the adult diaper can be visually indicated by the color change of the indicator (80).

[0058] The present invention has been described with reference to one embodiment illustrated in the drawings, but this is merely illustrative, and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible therefrom.
