DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof sheet suitable for nursing a sick person.

[0002]

2. Description of the Related Art Conventionally, various disposable diapers have been used for the care of sick people. However, the use of diapers alone causes soiling of bedding such as futons when urine leakage or the like occurs.
Therefore, a waterproof sheet is laid on the futon or the like so as not to stain it.

[0003]

However, generally used waterproof sheets have high water-proof properties but hardly absorb water. Therefore, if diaper change is delayed or urine output is large, urine leakage will occur, not only contaminating the underwear and bedclothes worn, but also easy to flow to places where waterproof sheets are not laid, futon Even bedding such as will be soiled. In particular, when the sick person becomes slightly demented, it fails to use the simple toilet placed on the bed and urinates on the bed, or urinates when the diaper is removed by changing diapers. .

[0004] In addition, the waterproof sheets must be replaced each time they become dirty, but they are leased at hospitals, and a lease fee of about 250 yen per sheet is required. Becomes difficult. In addition,
Waterproof sheets may be purchased and used without lease,
Since it costs 2000 to 3000 yen per sheet, if the number of stains per day is large, the number of purchased sheets naturally increases, and the economic burden is also serious.

The present invention has been made in view of such conventional problems, and is excellent in both waterproofness and water absorption, does not stain beddings such as futons, can be replaced only in dirty portions, and is disposable. It is an object of the present invention to provide a disposable diaper-connected waterproof sheet that can be separated and used as a diaper and requires less economic burden.

[0006]

In order to achieve the above-mentioned object, a disposable diaper-connected waterproof sheet according to the present invention comprises a plurality of flat disposable diapers having a water-absorbing layer on the inner surface and a waterproof layer on the outer surface. Combine and configure. And
On the waterproof layer on the connecting edge of each of the above disposable diapers,
A waterproof protective layer for protecting the waterproof layer is formed, and an adhesive tape coated with an adhesive is applied over one of the two waterproof protective layers on the adjacent disposable diaper to form a diaper connection layer.

It is preferable that the waterproof protective layer is formed using an adhesive tape coated with an adhesive on one side. or,
Preferably, the number of connected flat disposable diapers is three. Further, it is preferable that the end of the pressure-sensitive adhesive tape forming the diaper connection layer is folded back and adhered to form a knob.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the attached FIGS. FIG. 1 is a bottom view of a disposable diaper-connected waterproof sheet to which the present invention is applied, and FIG.
Is a plan view thereof. This disposable diaper connection type waterproof sheet 1 is manufactured by connecting a plurality of flat disposable diapers 2. At that time, as the flat type disposable diaper 2, for example, a commercially available 72 cm long and 30 cm wide
A rectangular one having a thick water-absorbing layer 3 made of paper on its inner surface and a thin waterproof layer 4 made of a plastic sheet on its outer surface is used. Then, three disposable diapers 2 are arranged in the lateral direction, and the edges of the adjacent diapers 3 are brought into contact with each other, so that their width can be made slightly wider than the standard bed width installed in the hospital. .

However, since the waterproof layer 4 of such a disposable diaper 2 is thin and weak, it is necessary to protect the waterproof layer 4 so as not to be damaged at a place where external force is applied. Therefore, a waterproof protective layer 5 having a constant width is formed on the waterproof layer 4 at the connecting edge of each disposable diaper 2 to protect the waterproof layer 4 from damage. At this time, using a pressure-sensitive adhesive tape coated with an adhesive on one side, for example, a 25-mm-wide rubber tape, and bonding the rubber tape on the waterproof layer 4 at the connection edge, it is possible to easily provide strong waterproof protection at any point. Each of the layers 5 can be formed.

Therefore, as shown in FIG. 3, an adhesive tape coated with an adhesive on one side, for example, a gum tape having a width of 35 to 40 mm is evenly spread over the two waterproof protective layers 5 of the adjacent disposable diapers 2 and adhered. Then, the adjacent disposable diapers 2 can be easily connected to each other, and the diaper connection layers 6 each having a fixed width made of a high-strength adhesive tape such as a gum tape can be formed at predetermined positions, respectively. 1 is completed. In addition, when the diaper connection layer 6 is formed in this manner, even if the diaper connection layer 6 is peeled off, the waterproof layer 4 of each disposable diaper 2 is protected by the waterproof protective layer 5, so that the waterproof layer 4 is not damaged. It can be easily peeled off from both waterproof protective layers 5,
The disposable diaper 2 can be reused. If both ends of the pressure-sensitive adhesive tape forming the diaper connection layer 6 are folded back inward and adhered, the diaper connection layer 6 can be more easily peeled off with the knob portion 7.

The disposable diaper-connected waterproof sheet 1 is about 2 cm wider than the bed width, is laid as a large sheet on bedding such as a futon, and is used so that the buttocks of a sick person are placed on the center of the waterproof sheet 1. . Then, since the waterproof sheet 1 is excellent in water absorption as well as waterproofness, even if urine leakage or the like occurs, urine does not spread and water is absorbed only at the leaked portion, so that the waterproof sheet 1 is not stained widely. . In particular, even if urine is discharged when the diaper is removed, such as in a toilet or when changing diapers, bedding such as a futon does not need to be soiled.

Then, the dirty waterproof sheets 1 may be appropriately peeled off the adhesive tape forming the diaper connection layer 6, and only the dirty portion of the disposable diaper 2 may be separated and discarded. Moreover, when only one disposable diaper 2 at the end is soiled, the remaining portion can be used as a narrow sheet as it is. Alternatively, by replacing one of the sheets with a new one and forming the diaper connection layer 6 using the adhesive tape that has been peeled off or a new adhesive tape, the waterproof sheet 1 can be easily reproduced and used. Moreover, such a disposable diaper-connected waterproof sheet 1 can be used individually as three diapers 2 when the adhesive tape forming the diaper connection layer 6 is peeled off and separated as a disposable diaper 2, without taking up a place. . In addition, since the disposable diaper connection type waterproof sheet 1 only connects three disposable diapers 2, the economical burden is naturally reduced as compared with the conventional waterproof sheet.

In the above embodiment, the disposable diaper 2 is replaced by 3
The waterproof sheets 1 connected to each other have been described, but if the number of connected sheets is increased and the disposable diapers 2 are connected in the vertical direction or the like, a larger waterproof sheet can be manufactured.

[0014]

According to the present invention described above, claim 1
In the described invention, a waterproof sheet excellent in both waterproofness and water absorption can be manufactured by connecting a plurality of flat disposable diapers having a water-absorbing layer on the inner surface side and a waterproof layer on the outer surface side. Therefore, even if urine leakage occurs,
Urine does not spread and water is absorbed only at the leaked portion, so that the waterproof sheets are not stained widely. Even when urinating or the like when the diaper is removed, such as in the toilet or when changing the diaper, the bedding such as the futon is not stained.

[0015] Then, the dirty waterproof sheets are appropriately peeled off the adhesive tape forming the diaper connection layer, separated and discarded only the disposable diaper of the dirty portion, replaced with a new disposable diaper, and replaced with the adhesive tape previously peeled off. By forming a diaper connection layer using a new adhesive tape,
You can easily recycle disposable diaper-connected waterproof sheets. Moreover, when the adhesive tape forming the diaper connection layer is peeled off from the waterproof protective layer and separated as a disposable diaper, the disposable diaper connection type waterproof sheet can be used individually as a plurality of diapers, and does not take up a place. In addition, the disposable diaper-connected waterproof sheets are less economically burdensome than using conventional waterproof sheets.
