[0001]

TECHNICAL FIELD The present invention relates to a diaper for nursing care mainly for adults.

[0002]

2. Description of the Related Art In a conventional diaper device, it is general to stack water-absorbent cloth diapers on a crotch part, and then attach a diaper cover on the crotch part to fix the diaper cover to the waist part. In this case, in order to reduce the frequency of replacement work at night, the number of diapers to be stacked is increased. In addition, recently, a method of putting a disposable paper diaper on the crotch part and wearing a cloth diaper on it has been increasing.

[0003]

However, in the case of the cloth diaper described in the prior art, the physical burden of wearing work by a caregiver is large, and especially in the nighttime zone, the cloth diaper is used to increase the amount of water retention. It is bulky because it is worn in multiple layers, which gives the wearer an uncomfortable feeling,
It has the drawback of increasing the burden of washing and drying.

Most of the materials for cloth diapers are bleached cotton cloth. However, this cloth does not have elasticity and becomes stiff when wet, sore skin and leakage of large amounts of urine due to poor water diffusion. There are also problems such as occurrence.

In the method of using disposable paper diapers together,
It is not preferable in terms of effective use of resources and environmental protection as well as a large economic burden.

As means for solving these problems, the top sheet is a mesh or pile material, the water absorbing sheet is cotton or rayon and a nonwoven fabric made of polyester fiber, and the back sheet is an insert pad made of three kinds of sheets of waterproof cloth. There is also proposed a method of combining underpads having the same structure as this and having a larger size, washing and repeatedly using the same.

However, in these methods, the size is increased in order to secure a necessary water retention amount, the feeling of wearing is bad, the leakage of urine from the peripheral portion cannot be prevented, and when repeated commercial washing, the top There is a problem that a layer of lipophilic substance is formed on the surface of the sheet and the water absorption performance is significantly lowered.

The present invention has been made in order to solve the above-mentioned conventional problems, and its purpose is to reduce the burden on the caregiver in the wearing work and to make the wearer feel uncomfortable. No water absorption after repeated washing
It is an object of the present invention to provide a diaper device that does not deteriorate in water retention performance and is suitable for commercial laundry.

[0009]

In order to achieve the above object, the diaper device of the present invention comprises an insert pad and an underpad, and the insert pad is used on the skin side and then the underpad is used on the outer side thereof. Each is composed of a top sheet, a water absorbing sheet, and a back sheet.As the top sheet, a knitted fabric made of synthetic fiber filament yarn having excellent water absorbing and diffusing properties and having a thin brushed surface is used. Is a yarn having excellent water absorption and diffusibility due to a capillary phenomenon due to fine voids between fibers, and a polyester filament yarn (hereinafter referred to as polyester A and a polyester filament yarn having a cross section of a rectangle having a vertical / horizontal ratio of 3 or more or a wavy shape). And a multilayer knitted fabric consisting of cotton yarn as a hydrophilic fiber. The backsheet is made of elastic, breathable waterproof cloth. The peripheral portion is covered with a knitted fabric made of polyester A and cotton yarn in a pipe shape and sewn.

The top sheet of the insert pad absorbs moisture from the skin quickly and diffuses it to the water absorbing sheet. The water absorbing sheet absorbs water due to the strong capillary action of polyester A, and retains water with the cotton thread of the inner layer to prevent rewetting. It is preventing. Furthermore, the surface of the topsheet is raised to a thin brush to make the contact with the skin point contact, thereby removing the feeling of wetting. Polyester A with excellent water absorption and diffusion in the peripheral area
A knitted fabric made of cotton and cotton is used to prevent the uneven distribution of water.

The basic structure of the underpad is the same as that of the insert pad, and the underpad has a uniform structure over the entire area, and its main function is to back up the insert pad and absorb / hold stool.

As the insert pad of the present invention, two types having different water retention amounts can be used. As an insert pad used in the daytime where the caregiver is well watched, a water absorbent sheet is a synthetic fiber filament yarn excellent in water absorption / diffusion property, preferably a knitted fabric made of polyester A with a brushed surface Then, it is possible to use a type that has a necessary and sufficient amount of water retention for daytime use and a property of preventing rewetting and that further reduces the discomfort of the wearer by downsizing.

For nighttime when the caregiver has a long patrol interval, a multi-layered knitted fabric made of cotton yarn and polyester A, preferably polyester A, is used on the front and back sides of a water absorbent sheet, and hydrophilic fibers, preferably mercerized A type of cardboard knitted fabric with a textured cotton thread spun on it in multiple layers and concentrated at the hips to ensure the necessary water retention capacity and avoid unnecessary bulkiness. Is preferred.

[0014]

Embodiments of the present invention will be described below in detail with reference to the drawings. However, the configuration of the present invention is not limited to the present embodiment, and even if there are design changes and the like within the scope of the invention, they are included in the present invention.
FIG. 1 shows a state in which the insert pad and the underpad of the diaper device of the present invention are superposed. The shape of the insert pad is almost cocoon-shaped, with the larger one on the hips and the smaller one on the lower abdomen. The constricted portion in the center is in contact with the crotch area, and the gathers 5 for leak prevention are sewn on both sides.

As shown in FIG. 2, the insert pad for daytime uses a thin raised knitted fabric 6 as a top sheet, and also uses the same fabrics 7, 71 as a water absorbing sheet in a multi-layered manner to obtain a necessary and sufficient water retention amount. And a back sheet made of stretchable moisture-permeable waterproof cloth. The peripheral portion is made of a synthetic fiber filament yarn having excellent water absorption and diffusion properties, preferably a knitted fabric made of polyester A and cotton yarn to form the edge 3 to prevent uneven distribution of water and to be sewn so that the peripheral portion becomes thin and worn. It relieves the person's discomfort, especially the pressure on the sacrum.

In order to increase the water retention capacity, the insert pad for nighttime is constructed by intensively mounting the enhanced water absorbing sheet on the inner layer of the portion 4 shown by the one-dot chain line in FIG. 1. The sectional structure of the mounting portion is shown in FIG. As shown. This enhanced water-absorbent sheet is a knitted fabric having a multi-layered structure as shown in FIG. A cardboard knitted fabric in which front and back structures are connected as shown in FIG. 5 is laminated in multiple layers. Or, like 81 and 82 in FIG.
A knitted fabric having a two-layer structure composed of polyester A and cotton yarn may be laminated to be used in a multi-layer. Enhanced water absorbing sheet,
Efficiently retain water by arranging it intensively at 4 parts of FIG. 1, which is a part where urine collects in the actual wearing state, and avoid an unnecessarily large size. The periphery is covered with a knitted fabric made of polyester A and cotton yarn that has excellent water absorption and diffusion properties, and is sewn to reduce the thickness of the periphery to prevent uneven distribution of water and to prevent pressure on the sacrum. ..

As shown in the sectional structure of FIG. 4, the underpad 1 of FIG. 1 has a top sheet 6, a water absorbent sheet 8 of a multilayer knitted fabric made of polyester A and cotton yarn, a polyester processed yarn knitted fabric, and a polyurethane film or resin. It consists of a breathable waterproof cloth 9 processed and used. The function of the underpad is mainly to supplement the insert pad and to treat stool. Since the water absorption / diffusion property of the top sheet used in the present invention and the water absorption / water retention performance of the water absorption sheet are excellent, the water in the stool is immediately absorbed and the fluidity of the stool is lost, which is effective in preventing the leakage of stool. Also, the work of removing the stool from the underpad becomes extremely easy.

Polyester A used in the water-absorbent sheet of the insert pad and underpad of the present invention has a flat or flat corrugated cross-section, and has a water absorption rate by capillary phenomenon about twice that of ordinary polyester fiber and about 1% that of cotton. .5
Because it is twice as high, even thin fabrics spread throughout and show great water retention. Therefore, the thickness of the insert pad and the underpad can be reduced. In addition, when drying after washing, moisture is diffused to the outside air side to accelerate the drying. This is effective in reducing the burden of washing and drying and saving energy.

In addition to the effect of thinning described in the preceding paragraph, polyester A has a low flexural rigidity due to its flat cross-sectional shape. For this reason, both insert pad and underpad are wholly supple and soft to the touch. In the field of nursing care for the elderly, men who require long-term care often wear a disposable paper urine absorbing pad so as to wrap the penis. Conventional molded diapers cannot be used in this way due to the hardness and size of the product.For men, the one with a larger water absorption area has been attached to the front, but depending on the direction of the penis. Often causes urine leakage. Since the insert pad of the present invention is soft as a whole and the size is kept to the minimum necessary, it can be used in the same manner as the paper urine absorbing pad.

[0020]

As described above, the diaper apparatus according to claim 1 of the present invention is flexible and not bulky, and absorbs water.
Since it has excellent water retention performance, it does not give a feeling of leakage or discomfort to the wearer, the water absorption / water retention performance does not deteriorate even after repeated commercial washing, and the drying speed after washing is also fast. In addition, the burden on the caregiver in replacing the diaper is reduced.

In the insert pad and the underpad according to claim 2, the top sheet has good water absorption and diffusion,
Moreover, since it is brushed and the length of the legs is adjusted appropriately,
The point of contact with the skin is point contact, and you do not feel wet or stuffy. Further, in the case of a pile or mesh woven or knitted product, the lipophilic substance exudes from the inside by repeated washing and is concentrated in the convex portion of the woven or knitted structure, so that the water absorption is remarkably reduced. Since it is raised, no path for the lipophilic substance to seep out is formed, and therefore the water absorption performance does not deteriorate even after repeated washing. If the brushed hair is too long, the water absorption performance may decrease due to repeated washing, so the average length of the hair is 0.3 mm or more.
It is 1.2 mm, preferably 0.3 mm to 0.9 mm.

According to the insert pad of the third aspect, the insert pad has a necessary and sufficient water retention capacity for daytime use which can be seen by the caregiver, is small and supple, and is effective in reducing the discomfort of the wearer. By stacking a raised fabric, the raised layer maintains a fine space between the knitted fabrics and has the function of distributing water.
The water retention function is combined so that the water quickly diffuses and is retained throughout.

In the insert pad according to claim 4, water is absorbed by the strong capillarity of polyester A used for the water absorbent sheet, and the water is retained by the hydrophilicity of the cotton yarn located in the middle layer.
It does not easily get wet and does not make the wearer feel wet.
Further, as shown in FIG. 5, the multi-layered knitted fabric of the water absorbent sheet has the front surface and the back surface connected to each other, so that grooves are formed in the knitted fabric. When this is stacked in multiple layers, the groove has a function of accelerating the distribution of water.

According to the insert pad of the fifth aspect, in addition to the above effects, since the water absorbing sheet is concentratedly arranged in a portion where urine is collected in an actually worn state, it effectively retains water and avoids an unnecessarily large size. To improve the feeling of wearing and the washing and drying properties.

In the underpad according to claim 6, the water absorption and diffusivity of the top sheet and the water absorption and water retention of the water absorption sheet are excellent over the entire area, and the underpad functions as a backup of the insert pad and quickly absorbs moisture in the stool. Absorbs to prevent the flow of feces and facilitates the removal of feces from the underpad.

In the insert pad and the underpad according to the seventh aspect, the moisture in the peripheral portion is instantaneously diffused by the strong capillary action of the polyester A forming the edged knitted fabric, so that it does not accumulate or leak.
