Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof sheet for preventing excrement from penetrating clothes, sheets, and the like, and more particularly to a waterproof sheet that is worn by being wound around a cared person's torso.

Conventionally, a bedridden caregiver has been fitted with a flat diaper and a waterproof cover for covering the diaper to prevent excrements such as urine from leaking out of the cover.
However, excrement may leak from the gap between the cover and the body or between the legs, and it is imperative that the exudate adheres to the caregiver's clothing, bedsheets, quilts, etc. Could not be prevented. For this reason, the caregivers have to change their clothes and wipe their bodies more frequently, and the sheets and the like have to be replaced more frequently, which has been a burden on both the caregiver and the caregiver.
Therefore, in recent years, a technique for preventing a leaked substance from adhering to clothes, bed sheets, etc. has been developed, and some inventions or inventions have been already disclosed in connection with this.

Patent Document 1 discloses a device called a "waterproof sheet", which is related to a waterproof sheet for the purpose of preventing stains on a bed.
The device disclosed in Patent Document 1 will be described below. The invention disclosed in Patent Document 1 is a substantially rectangular waterproof sheet including a front sheet material and a back sheet material that are overlapped with each other, wherein the front sheet material is formed of a towel cloth and the back sheet material is made of a material having a waterproof function. Is formed.
In the invention having such characteristics, the waterproof sheet is spread on the bedclothes with the front sheet material of the towel cloth facing upward, and the care receiver wearing the sleepwear is laid down and used. Therefore, the feel of the front sheet material and the comfort of sleeping can be improved. In addition, by forming the back sheet material with a material having a waterproof function, it is possible to keep the bedding dirty when food or drink is spilled or when urine leaks, and it is possible to replace the dirty bedding. The burden can be reduced.

Next, Patent Document 2 discloses an invention relating to a waterproof sheet for the purpose of preventing stains on a bed under the name of "care waterproof sheet".
The invention disclosed in Patent Document 2 will be described below. In the invention disclosed in Patent Document 2, a water absorbing body having a size smaller than that of the waterproof sheet is arranged at the center of a waterproof sheet which is long in the width direction, and the water absorbing body absorbs a mixture of a polymer absorbent and pulp. It is characterized by being covered with.
In the invention having such characteristics, the water absorbing body is directed upward at an appropriate position of the bed to spread the waterproof sheet, and both ends of the waterproof sheet are woven and fixed between the bed mat and the bed. After that, the care receiver wearing clothes on the water absorbent body is laid down and used. Therefore, since the waterproof sheet is firmly fixed to an appropriate position on the bed, it is unlikely that the waterproof sheet will be displaced or loosened such as wrinkles. In addition, the leaked excrement quickly spreads to the front surface of the absorbent body and is absorbed by the polymer absorbent material. Therefore, since the excrement is not re-released due to pressure or the like, the bed mat can be protected from contamination.

The sheet body 2 has a rectangular shape surrounded by the first side 2a, the second side 2b, the third side 2c, and the fourth side 2d. That is, the first side 2a and the second side 2b are short sides facing each other, and the third side 2c and the fourth side 2d are long sides facing each other.
As will be described later with reference to FIG. 2, the lengths of the first side 2a and the second side 2b can cover the knee 53 from the torso 51 of the cared person 50 having an average body shape. Have a length of about. Further, the lengths of the third side 2c and the fourth side 2d are both longer than one round of the body 51 of the cared person 50 of the above-mentioned body type. However, the ratio of the lengths of the first side 2a to the fourth side 2d may be other than the above.

Further, the sheet body 2 has a rectangular third cloth 7 having the same area on the first cloth 5 near the first side 2a and on the second cloth 6 near the second side 2b. 8 are provided. More specifically, the third cloth 7 has its peripheral edge sewn to the first cloth 5.
The entire surface of the one third cloth 8 is adhered to the second cloth 6 by thermocompression bonding via the thermocompression bonding sheet 9B. In this way, the reason why the third cloth 8 is thermocompression bonded to the second cloth 6 instead of being sewn is that the waterproofness is impaired by the formation of minute holes in the second cloth 6 by the sewing. This is to avoid being
As the thermocompression bonding sheets 9A and 9B, known ones are used.

In detail, the 1st cloth 5 consists of towel cloth which has a loop pile, for example. This towel cloth is made of, for example, only cotton fibers or a mixed fiber made of synthetic fibers such as cotton fibers and polyester. When blended fibers are used, the blending ratio of cotton fibers and synthetic fibers is, for example, 80% and 20% by weight.
Next, the second cloth 6 is formed by coating the base material with a waterproof resin component such as polyurethane. A cloth made of synthetic resin such as polyester or nylon is used as the base material. In addition to this, as the second cloth 6, a cloth body made of synthetic resin fiber having waterproof property may be used.
Further, the third cloths 7 and 8 are made of a mixed fabric made of cotton fibers and synthetic fibers such as polyester. In this case, the mixing ratio of the cotton fiber and the synthetic fiber is, for example, 35% and 65% by weight. Therefore, the third cloths 7 and 8 have water absorbency and are improved in strength and shape retention property as compared with the first cloth 5. For the third cloths 7 and 8, for example, twill-woven cloth is used.

Next, the first fastening portion 3 is arranged near the first side 2a of the first cloth 5 and near the third side 2c. Specifically, the first engaging portion 3 is a surface fastener that is arranged on the surface of the third cloth 7 and is sewn to the third cloth 7 in advance. However, the first fastening portion 3 may be arranged along the entire length of the first side 2a of the first cloth 5 instead of the above.
On the other hand, the second fastening portion 4 is arranged on the side of the second cloth 6 where the first fastening portion 3 is not arranged. Therefore, in the above case, the second engaging portion 4 is arranged near the second side 2b and near the third side 2c. In addition, the second fastening portion 4 may be arranged along the entire length of the second side 2b of the second cloth 6. The second fastening portion 4 is also a hook-and-loop fastener that is placed on the surface of the third cloth 8 and is sewn to the third cloth 8 in advance.

Next, the operation of the waterproof sheet according to the embodiment of the present invention will be described with reference to FIG. FIG. 2 is a usage state diagram of the waterproof sheet according to the embodiment of the present invention. The constituent elements shown in FIG. 1 are designated by the same reference numerals in FIG. 2 and their description is omitted. Also, illustration of clothing of the cared person is omitted.
As shown in FIG. 2, the waterproof sheet 1, sheet 2, as the first side 2a and a second side 2b extends along the body axis A _B of the care 50, first fabric 5 side to be It is attached to the inside of the clothes of the care-receiver 50 in a state in which the care-giver 50 is directed to the body 51 side and wound around the body 51. That is, the sheet body 2 is sandwiched between the clothes and the diaper cover 60 worn by the care-receiver 50 with the second cloth 6 facing outward.

As a specific procedure for attaching the waterproof sheet 1, first, the first cloth 5 is laid on the back of the cared person 50 and below the buttocks, and then a part of the sheet body 2 near the second side 2b. Is hung so that the first cloth 5 directly contacts the diaper cover 60 on the abdomen 52 side of the care receiver 50.
Next, a part of the first side 2a side is hung from above a part of the second side 2b side hung on the abdomen 52 with the second cloth 6 on the upper side. By doing so, on the abdomen 52 side of the cared person 50, the first fastening portion 3 overlaps the second fastening portion 4, and these are fastened to each other and the third cloth 7, A mating portion 10 is formed in which 8 overlap each other. That is, the mating portion 10 is formed by superimposing the sheet body 2 near the first side 2a on the sheet body 2 near the second side 2b that contacts the diaper cover 60 of the care receiver 50.

Therefore, when the seat body 2 is mounted on the torso 51 of the cared person 50 by the mounting method described above, the seat body 2 extends from the torso 51 to the knee 53 of the cared person 50 over their entire circumference. The state is covered over.
At this time, on the back side of the cared person 50, the first cloth 5 surrounds the rear surface and the left and right side surfaces of the diaper cover 60.
Therefore, since the leaked material leaked from the gap between the diaper cover 60 and the back of the care receiver 50 or the gap between the diaper cover 60 and the buttocks descends to the bed side, respectively, the leak side does not leak to the back side of the care receiver 50. It is absorbed by the first cloth 5 wrapped around the side surfaces of the left and right bodies.
However, since the second cloth 6 is waterproof, the leaked substance absorbed by the first cloth 5 wrapped around the back side is prevented from passing through the second cloth 6. .. Therefore, the leaked substance is prevented from adhering to and penetrating the back side of the clothes of the care-receiver 50, the bed sheet, the hanging sheet and the like.

Further, on the abdomen 52 side of the cared person 50, the first cloth 5 near the second side 2b comes into direct contact with the diaper cover 60, and further the third cloth from the top of the second cloth 6 in this portion. 8, the third cloth 7, and the first cloth 5 near the first side 2a are sequentially stacked. Therefore, the leaked material leaked from the gap between the diaper cover 60 and the abdomen 52 or the gap between the diaper cover 60 and the groin is also absorbed by the first cloth 5 and the third cloth 7 and 8.
The leaked material absorbed by the first cloth 5 and the third cloths 7 and 8 is prevented from permeating by the doubled second cloths 6 and 6. It is prevented that the clothes adhere to the abdomen 52, the hanging sheets, the futon, etc., and penetrate.
In addition, when the first engaging portion 3 and the second engaging portion 4 are engaged with each other, the first side 2a is pressed while the portion of the sheet body 2 near the second side 2b is pressed. The mating portion 10 is opened by gripping and pulling away the portion close to it. Therefore, the third cloths 7 and 8 having higher strength and shape retention than the first cloth 5 are provided near the first side 2a and the second side 2b, respectively, so that Deterioration such as kinking and breaking is suppressed.

As described above, according to the waterproof sheet 1, on the back side and the abdomen 52 side of the care receiver 50, it penetrates into the clothes, the bed sheets and the bed sheets, the bed and the bed futon of the care recipient 50, respectively. Since this is prevented, the frequency of changing clothes of the care receiver 50 and the amount of laundry are reduced as compared with the conventional case, and the burden on both the care receiver 50 and the care receiver can be reduced.
Further, the trunk portion 51 can be covered over the entire circumference by a simple operation of facing the first cloth 5 side of the sheet body to the trunk portion 51 side and winding the sheet body. Therefore, even an inexperienced caregiver can quickly use the waterproof sheet 1.
Furthermore, in this work of winding, the caregiver does not have to hold the bedridden cared person 50. Therefore, also from this point, the burden on both the care receiver 50 and the care giver can be reduced.

Furthermore, according to the waterproof sheet 1, since the first cloth 5 and the third cloth 8 come into contact with the care receiver 50, the touch is good. In addition, since the leaked substance is promptly absorbed by the first cloth 5 and the third cloth 8, the leaked substance may adhere to the skin surface of the care-receiver 50 and cause discomfort or disease. It can be prevented.
Further, since the third cloths 7 and 8 are provided, deterioration of the mating portion 10 such as kinking and breaking is suppressed, so that the waterproof sheet 1 loses its shape even after repeated wearing and washing for a long period of time. The product life can be extended.
The waterproof sheet 1 can be easily manufactured by a method of heat welding relatively inexpensive cloth such as towel cloth or waterproof cloth. Therefore, since the manufacturing cost becomes low, it can be expected that the waterproof sheet 1 can be easily introduced into a nursing facility, a hospital, a general household or the like.
