Description

  The present invention relates to a disposable diaper that is attached to a person's lower abdomen, crotch, and buttocks and receives excrement so as not to attach to clothes.

  Conventionally, as this type of disposable diaper, for example, the one described in Patent Document 1 is known.

  As shown in FIG. 7, the disposable diaper Da includes an absorbent sheet 10 that is attached to the lower abdomen, crotch, and buttocks of a person and that can absorb excrement, and a water-impermeable cover 20 that covers the absorbent sheet 10. And a barrier pad 30 that is attached to the buttocks side of the absorbent sheet 10 and blocks excrement that tends to flow out to the back side.

When using this disposable diaper Da, the absorbent sheet 10 side is on the inside, and it is attached to a person so that the barrier pad 30 is in close contact with the person's buttocks.
In the wearing state of the disposable diaper Da, if there is excrement such as large and small urine from the wearing person, the absorbent sheet 10 absorbs it. In this case, for example, when the person wearing at bedtime is lying on his / her back, the barrier pad 30 is in close contact with the buttocks even if the excrement leaks from the inside of the disposable diaper Da to the back side. Therefore, the excrement is blocked by the barrier pad 30 and is difficult to leak out.

JP-A-10-192338

By the way, in such a conventional disposable diaper Da, the absorbent sheet 10 absorbs excrement, and further, the barrier pad 30 blocks leakage to the back side. The excrement gradually penetrates into the side of the barrier pad 30. Further, when the barrier pad 30 gets wet with the excrement, the buttocks hit by the barrier pad 30 get wet with the excrement, which may cause discomfort. There is a problem that there is. In addition, it is stimulated by excreta, and is likely to cause dermatitis.
The barrier pad 30 may protrude from the absorbent sheet 10, and when it gets wet, the friction between the buttocks and the barrier pad 30 increases and this part is strongly stimulated, causing dermatitis. It becomes easier. In particular, for example, when the wearer is not able to move the body with a heavy care recipient and is lying down for a long time, the barrier pad 30 strongly abuts against the buttocks for a long time and adheres closely. In the worst case, pressure ulcers may develop in the buttocks where the barrier pad 30 is in close contact.

  The present invention has been made in view of the above problems, and provides a disposable diaper that makes it difficult to wet the barrier pad, reduces the discomfort of the wearer, and can suppress the onset of dermatitis and pressure ulcer. For the purpose.

  A disposable diaper of the present invention for achieving such an object includes an absorbent sheet that can be attached to a person's lower abdomen, crotch, and buttocks and that can absorb excrement, and a water-impermeable sheet that covers the absorbent sheet. In a disposable diaper provided with a cover and a barrier pad attached to the buttocks side of the absorbent sheet and blocking the excrement that tends to flow out to the back side, moisture is blocked between the absorbent sheet and the barrier pad. It is set as the structure which provided the water-impermeable blocking sheet.

When using this disposable diaper, the barrier pad is closely attached to the buttocks and attached to the lower abdomen, the crotch and the buttocks.
In this state, when a person wearing a disposable diaper excretes excrement, the excrement is absorbed by the absorbent sheet. The absorbed excreta gradually permeates the entire surface of the absorbent sheet.
At this time, even if the excrement that has penetrated into the buttocks side penetrates to the place where the barrier pad is, the barrier pad is separated from the absorbent sheet by the blocking sheet, so the excrement absorbed by the absorbent sheet is on the barrier pad side. Infiltration is prevented. For this reason, the surface of the barrier pad is hardly wetted, so that a situation that causes discomfort to the wearer can be prevented, and an increase in friction between the skin and the barrier pad can be suppressed. The onset of pressure ulcer can be suppressed.

In addition, for example, when the wearer is lying on his / her back, excrement cannot be absorbed by the absorbent sheet and the barrier pad blocks the diaper's back even if it is about to leak out. Therefore, it is possible to prevent the excrement from leaking to the outside of the diaper, and to prevent, for example, the fouling of a bandage around the wearer.
In addition, when the barrier pad is also capable of absorbing excrement, the excrement that leaks to the back side can be absorbed to some extent, so that discomfort can be prevented in this respect as well. In addition, sweat can be absorbed, and discomfort can be prevented in this respect.
Furthermore, since the barrier pad protrudes from the absorbent sheet, an acupressure effect on the wearer's buttocks can be expected.

  In addition, if necessary, a subpad is provided between the blocking sheet and the absorbent sheet so that the end portion is connected to the absorbent sheet and can absorb excrement, and moisture is shielded at the joint between the subpad and the absorbent sheet. A shielding sheet is interposed.

According to this, since the joint part with the absorption sheet is separated by the shielding sheet in the subpad, when the excrement absorbed by the absorption sheet permeates into the buttock side, the subpad is connected to the absorption sheet. The excrement of the absorbent sheet penetrates from the end.
In this case, since the absorption path is longer by the amount of the subpad connected to the absorbent sheet, the excrement from the absorbent sheet gradually permeates into the subpad from the end, and excreted throughout the subpad. It is possible to delay the spread of the object, and also to delay the infiltration of excrement from the subpad through the periphery of the blocking sheet to the barrier pad. That is, when there is no subpad and shielding sheet, the absorbent pad that has absorbed excretion may permeate the barrier pad through the periphery of the shielding sheet and get wet, but the subpad and shielding sheet are provided. In some cases, the time for excrement to spread throughout the subpad is delayed, so that the time it takes for the barrier pad to penetrate from the subpad through the perimeter of the blocking sheet is delayed.
For this reason, even when a disposable diaper is worn for a long time, such as during sleeping, and excretion of excrement is repeated, the time until the barrier pad gets wet can be delayed to make the barrier pad difficult to get wet.
Further, since the absorption capacity is increased by the amount of the subpad, for example, even when worn for a long time such as at bedtime, it is possible to cope with these even if excretion of excrement is repeated.

Furthermore, if necessary, the subpad is meandered and superimposed, and a shielding sheet that shields moisture is interposed in the overlapping portion.
In this case, since the subpads are superposed, the absorption path is further increased as compared with the case where the subpads are single, and the permeation of excrement that is to reach the entire absorbent sheet can be further delayed.

Next, on the lower abdomen side of the absorbent sheet, a urine absorption pad that can adhere to the genital area and absorb excrement is provided.
Thereby, when the wearer of the disposable diaper excretes the urine, the urine collection pad mainly absorbs the urine. At this time, since the urine is absorbed by the urine collection pad, it is possible to make it difficult for the urine to go around the buttocks side of the absorbent sheet. Therefore, the penetration of excrement into the buttocks side of the absorbent sheet can be delayed, and the penetration of excretion through the periphery of the blocking sheet to the barrier pad can be delayed.

Moreover, since the absorption capacity of excrement is increased by the amount of the urine collection pad, for example, even when worn for a long time during sleeping or the like, excretion of excrement can be accommodated.
In this case, when the wearer is a woman, the effect can be exhibited particularly. That is, since this urine collecting pad is attached to the absorbent sheet and protrudes from the absorbent sheet, if the wearer of the disposable diaper is a woman, the urine collecting pad closely adheres to the outer shape of the genital area and most of the urine is collected. It is absorbed by the pad.

In addition, if necessary, the end of the urine absorbing pad is connected to the absorbent sheet, and the urine absorbing pad is meandered and superimposed, and a shielding sheet that shields moisture is interposed in the overlapping overlapping portion. is doing.
In this case, urine penetrates by meandering from the top side of the urine collection pad toward the base end side. Therefore, the absorption path of the urine absorption pad can be lengthened, and the time to reach the absorption sheet can be delayed compared to the case where the urine absorption pad is not meandered. It can be delayed and the penetration of excreta through the periphery of the blocking sheet to the barrier pad can be delayed.

  According to the disposable diaper of the present invention, since the non-permeable barrier sheet that blocks moisture is provided between the absorbent sheet and the barrier pad, the excrement absorbed in the absorbent sheet penetrates to the place where the barrier pad is located. Even if it does, the situation where excrement absorbed by the absorbent sheet penetrates to the barrier pad side is prevented, the surface of the barrier pad becomes almost damp, and the situation that causes discomfort to the wearer is prevented, and the skin The increase in friction between the skin and the barrier pad can be suppressed, and the onset of dermatitis can be suppressed.

  Hereinafter, based on an accompanying drawing, a disposable diaper concerning an embodiment of the invention is explained in detail.

  1 to 3 show a disposable diaper D1 according to the first embodiment of the present invention. This disposable diaper D1 is attached over the lower abdomen 1, crotch 2 and buttocks 3 of the person P, can absorb the excrement, the non-permeable cover 20 which covers the absorbent sheet 10, and the absorption It is set as the structure provided with the barrier pad 30 attached to the collar part 3 side of the sheet | seat 10, and blocking the excretion which is going to flow out to the back part 4 side.

The absorbent sheet 10 includes an absorbent member 11 that absorbs excrement and a nonwoven fabric 12 that covers the surface of the absorbent member 11 therein.
The absorbent member 11 is made of cotton-like pulp, and the cotton-like pulp contains a polymer absorbent.
Moreover, a deodorant is put in the absorbing member 11.

The nonwoven fabric 12 is formed of, for example, a fiber such as polyester or polypropylene, and allows water to pass therethrough. However, when the absorbing member 11 absorbs water, the nonwoven fabric 12 does not hold water by itself.
The cover 20 is formed of, for example, a polyethylene film.
The barrier pad 30 is interposed between the absorbent member 11 of the absorbent sheet 10 and the nonwoven fabric 12 and attached to the absorbent sheet 10. This barrier pad 30 is comprised by the same absorption member as the absorption member 11 of the absorption sheet 10, and absorption of excrement is possible.

In addition, a water-impermeable blocking sheet 35 that blocks moisture is provided between the absorbent sheet 10 and the barrier pad 30. The blocking sheet 35 is formed of, for example, a polyethylene film.
Further, a urine absorption pad 40 that can be in close contact with the genital part 5 is attached to the lower abdomen 1 side of the absorbent sheet 10. For example, the urine absorbing pad 40 is integrally formed with the absorbent member 11 of the absorbent sheet 10.

Gathers 21 are provided on both side edges of the absorbent sheet 10 and the cover 20 so as to be in close contact with the crotch 2.
Furthermore, an adhesive material 22 is provided on the surface of the cover 20 so that it can be attached to the underwear 8 such as pants covering the outside of the disposable diaper D1 or another diaper when worn. The adhesive material 22 is covered with a protective sheet (not shown) so that the adhesive force of the adhesive material 22 can be maintained before use. The protective sheet is peeled off in a timely manner when the disposable diaper D1 is used.

  When wearing this disposable diaper D1, as shown in FIG. 1, for example, the protective sheet is peeled to expose the adhesive material 22, and the lower abdomen 1, crotch 2 and underwear 8 of the underwear 8 such as pants or another diaper The disposable diaper D1 is attached with the cover 20 facing the underwear 8 side so that the barrier pad 30 is in contact with the heel part 3 and the urine collecting pad 40 is in contact with the genital part 5 inside the part covering the heel part 3. And the person P is put on the underwear 8 to which this disposable diaper D1 is attached. In the mounted state, the urine collecting pad 40 is in close contact with the genital part 5 and the barrier pad 30 is in close contact with the heel part 3. At this time, the disposable diaper D <b> 1 is fixed to the underwear 8 with the adhesive material 22, and thus is less likely to be displaced with respect to the underwear 8.

In this state, when the person P wearing the disposable diaper D1 excretes excrement, when the excrement is urine, the urine collection pad 40 mainly absorbs the urine. At this time, since the urine is absorbed by the urine collecting pad 40, it is difficult to go around the heel part 3 side of the absorbent sheet 10.
Further, at this time, in the case where the wearing person P is a woman, the effect can be exhibited particularly. That is, since the urine removing pad 40 is attached to the absorbent sheet 10 and protrudes from the absorbent sheet 10, if the person P wearing the disposable diaper D1 is a woman, the urine collecting pad 40 is closely attached to the outer portion 5 of the genital area 5. Most of the urine is absorbed by the urine collecting pad 40.
Moreover, since the absorption capacity of excrement increases by the amount of the urine collection pad 40, for example, even when worn for a long time during sleeping or the like, even if excretion of excretion is repeated, these can be absorbed.

  Further, when stool is excreted, it is mainly absorbed by the absorbent sheet 10. Since most of the urine is absorbed by the urine collecting pad 40, the absorbent sheet 10 can sufficiently exhibit its absorption performance. Therefore, the absorbent sheet 10 can reliably absorb stool moisture.

In this way, the urine absorbing pad 40 and the absorbent sheet 10 repeat excretion of excreta, and the absorbed moisture gradually permeates the entire surface of the absorbent sheet 10.
At this time, since the barrier pad 30 is separated from the absorbent sheet 10 by the blocking sheet 35, excrement absorbed by the absorbent sheet 10 does not penetrate into the barrier pad 30 side. For this reason, the surface of the barrier pad 30 is hardly moistened, so that it is difficult for the person P to feel uncomfortable. Further, an increase in friction between the skin and the barrier pad 30 can be suppressed, and dermatitis can be hardly caused.
Further, since the urine collecting pad 40 is provided to make it difficult for the urine to go around the buttock 3 side of the absorbent sheet 10, it is possible to delay the permeation of excrement into the buttock 3 side of the absorbent sheet 10, and It is possible to delay the permeation of excrement that tries to reach the barrier pad 30 through a long time, and it is possible to cope with wearing for a long time.

  For example, when the person P who wears is lying on his back, the excrement may not be absorbed by the urine absorbing pad 40 and the absorbent sheet 10 and will leak to the back 4 side of the disposable diaper D1. Even so, the barrier pad 30 blocks this. Therefore, the situation where excrement leaks to the outside of the diaper D1 can be prevented, and, for example, fouling such as a basket can be prevented.

Moreover, since the barrier pad 30 protrudes from the absorbent sheet 10 when lying on its back, an acupressure effect on the buttocks 3 of the person P who wears it can also be expected.
Furthermore, even if the person P who wears sweats, this is absorbed by the barrier pad 30, so that the surface of the barrier pad 30 can be hardly moistened so that the person P who wears can hardly feel discomfort. Moreover, the increase in friction between the skin and the barrier pad 30 can be suppressed, and the onset of dermatitis and pressure ulcer can also be suppressed.
After excretion of the excrement, the dirty disposable diaper D1 is removed and a new disposable diaper D1 is attached to the person P.

Next, FIG. 4 shows a disposable diaper D2 according to the second embodiment of the present invention.
This disposable diaper D2 has a sub pad 15 that is connected to the absorbent sheet 10 between the blocking sheet 35 and the absorbent sheet 10 and capable of absorbing excrement with respect to the disposable diaper D1 of the first embodiment. The difference is that a shielding sheet 17 that shields moisture is interposed at the joint 16 between the subpad 15 and the absorbent sheet 10.
The subpad 15 is composed of an absorbent member 11 similar to the absorbent sheet 10. The subpad 15 is connected to the absorbent sheet 10 at the end on the back 4 side.
The shielding sheet 17 is formed of, for example, a polyethylene film.
In the embodiment, the shielding sheet 17 also covers the end surface of the subpad 17 on the crotch 2 side.
Other configurations are the same as those described above.

When the disposable diaper D2 is to be worn, it is attached to the underwear 8 in the same manner as described above, and the underwear 8 is worn by the person P and worn.
Then, when the person P excretes excrement, the excrement is absorbed by the urine collecting pad 40 and the absorbent sheet 10 as described above. If there is excrement that is about to leak out on the back 4 side, the excrement is blocked not only in the barrier pad 30 but also in the subpad 15.
Further, since the absorption capacity is increased by the amount of the subpad 15, for example, even when worn for a long time such as at bedtime, excretion of excrement can be dealt with.

Further, since the absorbent pad 10 and the joint 16 are separated from each other by the shielding sheet 17 in the subpad 15, when the excrement absorbed by the absorbent sheet 10 penetrates to the heel part 3 side, the absorbent sheet 10 The excrement of the absorbent sheet 10 permeates from the end portion that is continuously provided. Thereby, compared with the case where there is no shielding sheet 17 and the entire surface of the subpad 15 is connected to the absorbent sheet 10, the excrement from the absorbent sheet 10 gradually permeates into the subpad 15 from the end portion. It is possible to delay the spread of excrement throughout. For this reason, since the absorption path becomes longer by the amount of the subpad 15 provided continuously with the absorbent sheet 10, the excrement from the absorbent sheet gradually permeates into the subpad 15 from the end portion. It is possible to delay the spread of excrement throughout 15. Therefore, the permeation of excretion from the sub pad 15 through the periphery of the blocking sheet 35 to the barrier pad 30 can also be delayed.
That is, in the absence of the subpad 15 and the shielding sheet 17, even if the shielding sheet 35 is present, the absorbent sheet 10 that has absorbed excretion penetrates the barrier pad 30 through the periphery of the shielding sheet 17 and the barrier pad 35 is wetted. However, when the subpad 15 and the shielding sheet 17 are provided, the barrier pad 30 is provided on the absorbent sheet 10 via the shielding sheet 35 and the subpad 15, and the subpad 15 is the shielding sheet 17 and the subpad. Since the excrement is spread throughout 15, the time for penetrating the barrier pad 30 from the subpad 15 through the periphery of the blocking sheet 17 is delayed.
For this reason, even when a disposable diaper is worn for a long time during sleeping or the like, the time until the barrier pad 35 gets wet can be delayed.
Other operations and effects are the same as those described above.

Next, FIG. 5 shows a disposable diaper D3 according to the third embodiment.
This disposable diaper D3 is different from the disposable diaper D2 according to the second embodiment described above, and the thickness of the absorbent sheet 10 on the side of the buttock 3 where the joint portion is connected to the subpad 15 is the thickness of the general part of the absorbent sheet 10. It is formed larger than this.
Further, the end portion of the urine collecting pad 40 is connected to the absorbent sheet 10, and the urine collecting pad 40 is meandered and superimposed, and a shielding sheet 45 that shields moisture is interposed in the overlapping portion 44 that overlaps. .
The shielding sheet 45 is formed of a polyethylene film or the like.
Other configurations are the same as those of the second embodiment.

When this disposable diaper D3 is to be worn, it is attached to the underwear 8 in the same manner as described above, and this underwear 8 is put on a person P and worn.
When the person P excretes urine, the urine collecting pad 40 absorbs it.
At this time, the urine collection pad 40 is meandered and superimposed, and a shielding sheet 45 that shields moisture is interposed in the overlapped portion, so that the urine is located at the base end portion from the top side of the urine collection pad 40. Meander to the side and penetrate. In other words, the urine absorption path of the urine absorbing pad 40 is meanderingly long, and the permeation of excretion to the buttocks 3 side of the absorbent sheet 10 can be delayed as compared with the case where the meandering is not conducted. Therefore, the permeation of excrement reaching the barrier pad 10 through the periphery of the blocking sheet 35 can be delayed, and can be applied even for a long time. The other actions and effects are the same as those of the second embodiment. It is the same.

Next, as shown in FIG. 6, the disposable diaper D4 which concerns on 4th embodiment is demonstrated.
Unlike the disposable diaper D3 of the third embodiment, the disposable diaper D4 includes a shielding sheet 17 that shields moisture from the overlapping portion 18 that superimposes the subpad 15 in a meandering manner. The end surface of the subpad 15 on the crotch 2 side is covered with the shielding sheet 17 as in the above embodiment.
Other configurations are the same as those of the disposable diaper D3 of the third embodiment.

In this case, since the subpad 15 is superposed, the absorption path is further increased as compared with the case where the subpad 15 is single, and the permeation of excrement trying to reach the entire absorbent sheet 15 can be further delayed. .
Other operations and effects are the same as those of the third embodiment.
