JP6370623B2 - Disposable pad - Google Patents

Description

  The present invention relates to a disposable pad, which is provided with a damming bridge in the middle to prevent forward movement of stool excreted in the rear part of a vertically long hole to prevent urinary tract infection due to attachment of stool in women, and scrotum in men The urine can be worn and used for a long time by preventing the attachment of stool on the backside of the body and so that urine can be absorbed and accumulated until the entire area of the absorbent layer is full without feeling uncomfortable. The present invention relates to a pad that reliably prevents the onset of pressure sores, rashes, etc. by continuing the dry state.

The applicant of the present application has previously proposed Japanese Patent Application Laid-Open No. 2007-125157. The gazette does not allow menstruation and urine to permeate into the internal absorbent layer and leaks out. Therefore, it does not smell the surroundings, does not cause rashes, pressure ulcers, daytime / nighttime disposable pants including children, and sanitary napkins. , Disposable diapers and urine-removing pads, wrapping the inner and outer surfaces in a completely waterproof form with an impervious sheet, with the absorbent material layer sandwiched between them, and urine etc. A sanitary and urine-disposable disposable pants, a diaper, a napkin, and a pad are provided, which are provided with a long hole extending between before and after flowing into the absorbent layer.

  However, since there is no means for preventing the forward movement of the stool excreted in the rear part of the long hole, the gazette moves forward to the front part of the long hole and touches the female urinary tract to contact the urinary tract There is a problem that it cannot withstand long wear because it causes infection and becomes uncomfortable by being attached to the back of a male scrotum.

  Further, there is a problem that slack occurs between the rear end portion of the long hole and the wearer's puffy buttock so that excreted urine oozes out to the buttock and further sweat accumulates. Therefore, the pad had the subject that it was restricted to wearing for a short time.

  In the present invention, the bridge gathers for damming are formed in the middle of the vertical hole of the pad, and the urine excreted in the rear part of the vertical hole is blocked to prevent forward movement, thereby preventing urinary tract infection due to stool attachment. In addition, the back of the scrotum should be kept clean so that it is clean, and the rear edge of the elongated hole is placed over the center of the wearer's inflated buttock with the center angle sandwiched. Even if the urine excretion is repeated by providing a permeable property part on the back side of the curved edge, there is no leakage to the buttocks, and sweat is permeable to the pad in a dry state. The problem was solved by making it comfortable to wear for a long time.

Since the disposable pad of the present invention prevents forward movement of excreted stool, it prevents the onset of infection due to urinary urinary tract attachment, and also makes it uncomfortable by preventing attachment to the back of the scrotum. Furthermore, the urine can be permeated through the entire area of the absorbent layer including under the stool, and it is possible to use the urine for a long time even by repeated excretion.

In addition, the disposable pad of the present invention forms an overhanging curved edge that contacts the flange with the central angle at the rear end of the vertically long hole, and maintains the dry state of the flange that contacts the protruding curved edge. By comprising the absorbent material layer including the permeable sheet, it is possible to prevent discomfort due to wetness of the buttocks even when worn for a long time .

  The present invention can be used as a pad worn by men and women who are bedridden mainly after illness or surgery by laying in a diaper cover, disposable diaper or pants, and the pad to be worn moves forward by excreted stool Thus, urinary tract infections caused by stool contact with the urinary tract in women are prevented, and stool is prevented from adhering to the back of the scrotum in men. Thus, the pad of the present invention can be worn for a long time more than twice the conventional pad.

  Also, the pad of the present invention is in close contact with the curved surface of the buttock that sandwiches the sacrum of the wearer so that there is no leakage. And a permeable part is formed on the rear side of the curved edge.

  1 to 3 show a first embodiment of the present invention, in which the outer side including the four circumferences of a vertically long absorbent layer 1 made of a polymer water-absorbing polymer or the like is surrounded by a waterproof sheet 2 and permeable to the inside. The sheet 3 is applied and the permeable sheet 3 is covered with a non-permeable permeable flexible material surface 4 which is soft to the touch to form an integrated pad 5. The flexible material surface 4 is provided with a vertically long hole 6 into which the stool a and the urine b enter back and forth, and a gather 7a is provided around the edge of the vertically long hole.

Further, a bridge gather 7b that crosses the stool a excreted in the rear part of the longitudinal hole 6 so as not to move forward is formed in the middle of the longitudinal hole 6.
The lower ends of these gathers 7 a and 7 b are bonded to the permeable sheet 3.

  The pad 5 thus formed is laid and worn in a diaper cover, disposable diaper / pants (both not shown).

  As shown in FIG. 2, the stool a is blocked by the bridge gather 7b and does not move forward, so the stool a does not touch the female urinary tract and the male scrotum. It will be possible to continue wearing cleanly without discomfort.

  Moreover, although the permeable sheet 3 is blocked by the bridge gather 7b, the absorbent material layer 1 communicates integrally with the front and back, so that the urine b which is usually frequent is contained in the absorbent material layer 1 below the stool a. It will be absorbed stably until it is full and can be worn for a long time. Further, even if there is no excretion of the stool a, the pad 5 is economical because it can be replaced after the urine is accumulated until the absorbent layer 1 is full.

  FIG. 3 shows a case in which a slack t is formed in the absorbent material layer 1, the waterproof sheet 2 and the permeable sheet 3 below the rear portion of the vertically long hole 6 in order to increase the amount of stool collected. Further, as shown in FIG. 4, the gathers 7a and 7b such as the four corners of the rear portion of the longitudinal hole 6 are extended to form a pocket p as shown by a dotted circle between the permeable sheet 3 and the flexible material surface 4, and The amount of reservoir may be increased to prevent stool leakage.

  FIG. 5 shows a second embodiment of the present invention, wherein the rear end of the longitudinally long hole 6 of the pad 5 is a protruding curved edge 9a, so as to be in close contact with the bulge of the buttocks with the central angle 8 in place of the gather 7a. 9b, and the rear side of the curved edges 9a, 9b is a permeable property portion 3a having a three-layer structure including the waterproof sheet 10, the extremely thin absorbent layer 11, and the permeable sheet 12 from the permeable sheet side 3. According to FIG. 5, the permeable part 3a has a leaf shape in plan view.

  As described above, even if the wearer keeps wearing the pad 5 for a long time, even if the buttock gets wet or sweat or the like flows, it is absorbed into the absorbent material layer 1 from the permeable sheet 3 and partly absorbed. By absorbing it into the material layer 11 and keeping the sacrum and the buttocks dry, it is possible to prevent the onset of pressure sores and rashes.

  In addition, as shown in FIG. 6, the slack t may be provided in the rear part under the vertically long hole 6 and the pocket P may be provided as in the previous example. Other configurations and operations are the same as those of the first embodiment.

  The present invention does not develop urinary tract infection or pressure ulcer due to excrement, and is widely used as a disposable pad that can repeatedly absorb excreted urine and can be worn for a long time.
