  However, the urine collection pad disclosed in Patent Document 1 has a structure that absorbs urine only by an absorber disposed in a portion other than the accommodation opening of the bag-like body. For this reason, when the urine excreted inside the urine collection pad flows back to the opening side due to the posture of the wearer or the like, the urine may leak to the outside from the opening.

  On the other hand, although the urine receiving device disclosed in Patent Document 2 includes a polymer absorbent sheet at the bottom of the attachment body, the bag itself does not include an absorber. For this reason, it is considered that the urine collected in the bag may flow back to the opening side vigorously at once. In such a case, all urine cannot be rapidly absorbed only by the polymer absorbent sheet of the attachment, and there is a possibility that urine leaks out from the opening.

  The present invention has been made in view of such circumstances, and while reducing the amount of urine flowing back to the opening, it quickly absorbs urine flowing back to the opening and prevents leakage of urine from the opening. An object of the present invention is to provide a urine absorbent article that can be used.

It is a general view of a urine collection pad. It is sectional drawing of the urine collection pad seen from the II-II position of FIG. It is the elements on larger scale of the vicinity of the opening part of a urine collection pad. 3 is a development view of the urine collection pad 1. FIG.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

<1. Configuration of urine collection pad>
FIG. 1 is an overall view of a urine collection pad 1 according to an embodiment of the present invention. 2 is a cross-sectional view of the urine collection pad 1 viewed from the position II-II in FIG. The urine collection pad 1 is a urine absorbing article that is attached to a male genitalia (penis) and absorbs urine excreted from the male genitalia. The wearer wears the urine collection pad 1 and wears a diaper or underwear thereon. If it is mild urination, only the urine collection pad 1 needs to be replaced without replacing the diaper or underwear, so the economic burden on the wearer and the care burden on the caregiver are reduced.

  The urine collection pad 1 has a bag 10 that can accommodate male genitalia. The bag 10 is formed with an opening 10a for inserting a male instrument. As shown in FIG. 2, the bag body 10 includes a liquid-permeable top sheet 11 that constitutes the inner side surface, a liquid-impermeable back sheet 12 that constitutes the outer side surface, and both the sheets 11 and 12. And a first absorber 13 interposed therebetween. When urine is excreted inside the bag body 10, the urine passes through the top sheet 11, but does not pass through the back sheet 12, and the first absorption is performed between the top sheet 11 and the back sheet 12. Absorbed and held by the body 13.

  The top sheet 11 is made of a nonwoven fabric using hydrophilic fibers (cellulose, rayon, cotton, etc.), for example. Moreover, the top sheet 11 may be comprised with the nonwoven fabric which processed the surface of hydrophobic fiber (a polypropylene, polyethylene, polyester, polyamide, nylon, etc.) with surfactant, and was made liquid-permeable.

  The back sheet 12 is made of, for example, a water-repellent nonwoven fabric using hydrophobic fibers (polypropylene, polyethylene, polyester, polyamide, nylon, etc.). The back sheet 12 may be made of a plastic film, or may be made of a plastic film and a highly flexible nonwoven fabric stuck on the outside thereof.

  The 1st absorber 13 is constituted by a sheet-like polymer absorber, for example, and is being fixed with an adhesive between top sheet 11 and back sheet 12. The first absorbent body 13 is a paper sheet such as tissue paper or a liquid-permeable non-woven fabric obtained by mixing a granular polymer absorbent body with an aggregate layer of pulverized hydrophilic fibers such as pulp fibers and cellulose fibers. You may be comprised by what was coat | covered with the coating sheet of the sheet | seat.

  In addition, if the 1st absorber 13 is comprised with a polymer absorber without pulp, the absorber 13 can be formed thinly. For this reason, a sense of incongruity when the urine collection pad 1 is worn can be reduced.

  FIG. 3 is a partially enlarged longitudinal sectional view in the vicinity of the opening 10 a of the urine collection pad 1. As shown in FIG. 3, the urine collection pad 1 has a plurality of elastic members 14 extending along the opening 10a. Further, the back sheet 12 is folded inward so as to cover the plurality of elastic members 14 in the vicinity of the opening 10a. The plurality of elastic members 14 are sandwiched between folded portions of the back sheet 12 and fixed with an adhesive. As the adhesive, for example, a hot melt type adhesive is used.

  The plurality of elastic members 14 are fixed to the back sheet 12 in a state of being extended from the natural length. For this reason, the plurality of elastic members 14 generate an elastic force so as to shrink the opening 10a. On the other hand, the wearer or caregiver of the urine collection pad 1 can also widen the opening 10 a against the elastic force of the elastic member 14. For example, a polyurethane thread may be used for the elastic member 14, but a polyurethane film, natural rubber, or the like may be used.

  As shown in FIG. 3, the end side 11 a on the opening 10 a side of the top sheet 11 is located on the bottom side of the bag body 10 from the folded portion of the back sheet 12. That is, the end side 11 a on the opening 10 a side of the top sheet 11 is separated from the edge 10 c of the opening 10 a of the bag body 10. This prevents urine from penetrating to the edge 10c of the opening 10a through the top sheet 11.

  Moreover, the urine collection pad 1 of the present embodiment includes a second absorbent body 21 in the vicinity of the opening 10 a of the bag body 10. The second absorbent body 21 is disposed inside the bag body 10 from the folded portion of the back sheet 12. The second absorbent body 21 is fixed inside the liquid permeable water permeable sheet 22 with an adhesive. The second absorbent body 21 and the water permeable sheet 22 constitute an integral absorbent sheet body 20.

  As described above, the urine collection pad 1 of the present embodiment includes the first absorbent body 13 and the second absorbent body 21. The urine excreted inside the bag body 10 is first absorbed by the first absorbent body 13, thereby reducing the amount of urine flowing back to the opening 10 a. In addition, even when urine that has not been absorbed by the first absorber 13 flows back to the opening 10 a side, the urine is absorbed by the second absorber 21.

  In particular, the second absorber 21 is made of a material having a higher water absorption rate than the first absorber 13. For this reason, urine that has flowed back to the opening 10 a side is quickly absorbed by the second absorber 21. As a result, leakage of urine from the opening 10a to the outside is well prevented.

  Further, an opening sheet 30 is provided in the opening 10 a of the bag body 10. The opening sheet 30 is adhered from the inner surface of the absorbent sheet body 20 to the outer surface of the back sheet 12 via an adhesive. The position of the absorbent sheet body 20 is determined by being fixed between the back sheet 12 and the opening sheet 30. The opening sheet 30 is made of a liquid-permeable nonwoven fabric. Moreover, since the opening part sheet | seat 30 is comprised by the comparatively flexible nonwoven fabric, it also plays the role which relieves the wearer's contact | winning to skin and reduces irritation | stimulation with respect to skin.

  Further, as shown in FIG. 1, the bag body 10 is formed with a slit 10b that is cut from the edge 10c of the opening 10a toward the bottom. Moreover, the fixing member 40 which fixes the opening part 10a according to the size of the male genitalia is provided in the edge of the slit 10b. The fixing member 40 includes a base sheet 41 whose base end is attached to the edge of the slit 10 b of the bag body 10, and a male member 42 provided on the other end side of the base sheet 41. The male member 42 is made of, for example, a hook material of a hook-and-loop fastener, and can be attached to and detached from an arbitrary position on the surface of the opening sheet 30.

  The fixing member 40 does not necessarily have to attach the male member 42 to the opening sheet 30. For example, a female member (for example, a loop material of a hook-and-loop fastener) may be provided on the outer surface of the back sheet 12 near the opening 10a, and the male member 42 may be attached to the female member.

  FIG. 4 is a development view of the urine collection pad 1. The urine collection pad 1 is formed from a substantially rectangular laminate 2 in which a top sheet 11, a first absorber 13, and a back sheet 12 are laminated in this order. When the urine collection pad 1 is manufactured, first, the laminate 2 is bent so that the top sheet 11 is on the inner side of the folding line 2a extending in the width direction in the vicinity of the center in the longitudinal direction. And the urine collection pad 1 of the state of FIG.1 and FIG.2 is obtained by sealing the both sides of the laminated body 2 bent by the heat seal etc. in the longitudinal direction.

  When wearing the urine collection pad 1, first, the wearer or caregiver widens the opening 10 a of the urine collection pad 1. And the bag 10 is covered with a male genitalia in the state which opened the opening part 10a. When the wearer or caregiver removes his / her finger from the opening 10 a, the bag body 10 is fixed to the male genital by the elastic force of the elastic member 14. Thereafter, the wearer or caregiver attaches the male member 42 of the fixing member 40 to an appropriate position of the opening sheet 30. Thereby, the magnitude | size of the opening part 10a is adjusted according to the size of a male genitalia, and the urine collection pad 1 is firmly fixed with respect to a male genitalia.

  In particular, the urine collection pad 1 of the present embodiment has a slit 10b in the vicinity of the opening 10a, and a fixing member 40 is attached to the edge of the slit 10b. For this reason, it is possible to overlap the edges of the slits 10b by pulling the fixing member. Thereby, the magnitude | size of the opening part 10a can be adjusted, suppressing that a clearance gap generate | occur | produces between the opening part sheet | seat 30 and the male genitalia.

<2. About the second absorber>
As described above, the second absorbent body 21 is made of a material having a higher water absorption rate than the first absorbent body 13. For this reason, when the urine flows backward from the inside of the bag body 10 toward the opening 10 a, the urine can be quickly absorbed by the second absorbent body 21. As a result, leakage of urine from the opening 10a to the outside is well prevented.

  In comparing the water absorption speed of the first absorbent body 13 and the second absorbent body 21, for example, the water absorption time measured by the Vortex method defined in JIS standard K7224 (established in 1996) is the same as that of the first absorbent body 13 and the second absorbent body 21. What is necessary is just to compare with 2 absorbers 21.

  The outline of the water absorption rate test method based on the Vortex method will be described. (1) First, about 2.00 g of an absorber serving as a sample is weighed. (2) Next, in a 100 ml beaker with a flat bottom, 50 g of 0.9 ± 0.001 M / v% physiological saline and a stirrer chip (the diameter at the center is 8 mm, the diameter at both ends is 7 mm, the length Is 30 mm and coated with fluororesin), and the beaker is placed on a magnetic stirrer. (3) The rotational speed of the magnetic stirrer is adjusted to 600 ± 60 times per minute to confirm that the physiological saline generates a stable vortex. (4) After that, the absorber weighed in (1) is put in the vicinity of the inner wall surface of the beaker so as to be uniform, and a timer is started. (5) The time until the stirrer chip is covered with physiological saline (the time when the vortex disappears and the liquid level becomes flat) is measured, and that time is taken as the water absorption speed of the absorber.

  The Vortex method stipulated in JIS standard K7224 is intended for testing “a highly water-absorbent resin that absorbs water and expands highly”, but the first absorbent body 13 and the second absorbent body 21 include the standard. A material other than the “superabsorbent resin” defined in (1) may be used. When one or both of the first absorbent body 13 and the second absorbent body 21 is a material other than “a highly water-absorbing resin that highly absorbs water and expands”, the same material as the Vortex method is used as the sample. The time obtained when the test is performed may be the water absorption speed.

  In order to quickly absorb the urine flowing back to the opening 10a, the water absorption rate based on the Vortex method of the second absorber 21 is preferably 10 seconds or less, more preferably 5 seconds or less, and more preferably 3 seconds. More desirable if:

  The 2nd absorber 21 which has such a water absorption speed can be obtained by performing predetermined processing to superabsorbent resin, such as polyacrylic acid sodium, for example. It is desirable that the second absorbent body 21 is composed only of a polymer absorbent body obtained from a highly water-absorbent resin. However, as long as the water absorption speed of the second absorbent body 21 as a whole satisfies the above requirements. For example, other materials may be included. In addition, if a material other than the resin that satisfies the above water absorption rate requirement is found, it may be used for the second absorbent body 21.

  As shown in FIG. 3, the second absorbent body 21 is provided at a position inside the elastic member 14 and partially overlapping with the elastic member 14. For this reason, when the urine collection pad 1 is worn, the second absorbent body 21 comes into close contact with the male genitalia due to the contraction force of the elastic member 14. Thereby, the clearance gap between a male genitalia and the opening part sheet | seat 30 is obstruct | occluded, and the leakage of urine from the opening part 10a is prevented more reliably.

  Note that the entire second absorbent body 21 may be provided at a position overlapping the elastic member 14. However, as shown in FIG. 3 of the present embodiment, the end 21a on the opening 10a side of the second absorbent body 21 is desirably separated from the edge 10c of the opening 10a. In this way, it is possible to prevent urine from penetrating to the edge 10c of the opening 10a through the second absorbent body 21.

  Moreover, in this embodiment, the material which comprises the 2nd absorber 21 has a property expanded by water absorption. For this reason, the second absorbent body 21 expands when urine is absorbed, and further closes the gap between the male genitalia and the opening sheet 30. Thereby, leakage of urine from the opening 10a is more reliably prevented.

  The second absorbent body 21 is preferably in the form of granules or beads. If it is granular or beaded, the 2nd absorber 21 can be uniformly distributed inside the water-permeable sheet 22. For this reason, leakage of urine can be prevented more reliably over the entire circumference of the opening 10a.

  Moreover, in this embodiment, the edge part of the back seat | sheet 12 is return | folded so that the some elastic member 14 may be coat | covered. For this reason, the folded portion of the back sheet 12 is interposed between the elastic member 14 and the second absorbent body 21. Since the back sheet 12 is liquid impermeable, it is possible to prevent urine from penetrating from the second absorbent body 21 to the elastic member 14 side. In particular, even when the elastic member 14 is fixed with an adhesive that is weak against wetting, a decrease in the adhesive strength of the adhesive can be prevented.

<3. Modification>
Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment.

  In the above embodiment, the second absorbent body 21 is covered with the water permeable sheet 22, but the second absorbent body may be inserted directly between the opening sheet 30 and the back sheet 12. Good.

  Further, in the above embodiment, the inner side of the absorbent sheet body 20 is covered by the opening sheet 30, but the absorbent sheet body 20 is exposed to the inside of the bag body 10 without being covered by the opening sheet 30. It may be.

  Moreover, in said embodiment, although the bag body 10 was comprised by bend | folding the rectangular laminated body 2 and sealing the both sides, the bag body 10 is not necessarily the rectangular laminated body 2. May not be bent. For example, the bag body 10 may be configured by joining a plurality of laminated bodies.
