[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is a sectional view of a main part of an embodiment of a diaper according to the present invention. That is, the configuration of the diaper around the defecation portion of the buttocks 2 of the diaper wearer is shown.

The diaper is made of a soft, water-absorbing cloth member 4 such as a nonwoven fabric which comes into contact with the buttocks 2 of the diaper wearer.
A urine absorbing layer 6 containing an absorbing polymer and the like, a slightly thick urine absorbing layer 6, an inner waterproof sheet member (for example, a vinyl sheet) 7, and an outer waterproof sheet member 8 are sequentially provided on the outside. An opening having a diameter of about 3 cm is provided in the portion of the cloth-like member 4 at a position where the diaper is in contact with the toilet part 1 of the diaper wearer.

Further, a stool guide member 5 is arranged between the cloth-like member 4 and the urine absorbing layer 6 at a position corresponding to the defecation portion 1 of the diaper wearer. The stool guide member 5 includes a cloth-like member 4.
And the opening 3 penetrates the stool guide member 5 outward (to the lower side in the figure). Similarly, a through-hole is provided in the urine absorption layer 6 corresponding to the through-hole, and the through-hole is connected to the opening of the inner waterproof sheet member 7. These openings and through holes constitute a stool storage space (flight storage section) 9.
Further, the space between the inner waterproof sheet member 7 and the outer waterproof sheet member 8 is configured to be detachable from each other at least in the vicinity of the defecation portion 1, and the gap between the two sheet members 7, 8 may be increased depending on the amount of stool. It enlarges and expands the stool storage space 9.

FIG. 2 is a perspective view showing an example of the flight guide member 5 shown in FIG. The stool guide member 5 is composed of a synthetic resin plate 52 that is curved to correspond to a crack in the buttocks of a human, and a sponge (layered elastic member) 43 that is overlapped and coupled to the curved convex surface side. The synthetic resin plate 52 is for defining a certain initial shape, and also has a certain elasticity. Preferably, the size of the sponge 43 is adjusted so that the sponge 43 hides the periphery of the synthetic resin plate 52.
Larger than the size of. As described above, the stool guide member 5 has the opening 3. The opening 3 penetrates from the convex side to the concave side.

When the diaper structured as described above is worn on a care receiver or the like, the diaper is set so that the opening 3 of the stool guide member 5 is located at the defecation part 1 of the person. At that time, the diaper is lightly pressed from the outside of the diaper so that the stool guide member 5 is sandwiched between the meat portions on both sides of the buttocks 2. As described above, since the stool guide member 5 has elasticity, such attachment prevents the stool guide member 5 from coming off the predetermined position.

As described above, according to the diaper having the configuration shown in FIG. 1, the excreted stool is stored in the stool storage space 9, so that the stool is prevented from spreading on the skin surface of the diaper wearer as in the related art. Thus, the care of the caregiver can be reduced. Also,
For the diaper wearer, not only the risk of infection by bacteria is reduced, but also the odor is reduced because the area of contact with the outside air is reduced.

It should be noted that a urination / defecation sensor 20 as shown in FIG. 3 may be incorporated in the diaper. At that time, sensor 2
0 are prepared, one of which is used for urination and the other is used for defecation. The urination sensor 20 is disposed outside the inner waterproof sheet member 7 (on the buttocks 2 side).
Are disposed in the gap between the inner waterproof sheet member 7 and the outer waterproof sheet member 8.

In FIG. 3, a sensor 20 is formed by applying a water-repellent ink or paste such as a silicone resin on an elongated base 21 of paper, cotton or the like or a thin plastic sheet, and further applying a conductive ink or paste thereon. Is a printed conductive pattern. As the conductive ink or paste, a mixture of powder of a conductive substance such as silver or copper is used. The conductive pattern includes first and second substantially parallel strips 22 and 2 extending in the longitudinal direction of the substrate 21.
Consists of four. The pattern 29 of the water-repellent ink is printed so as to expose the defecation / urination detection section 33 and the terminal section 31 of the base material 21 and cover the remaining portion. Thereby, the portion of the base material 21 of the pattern 29 does not permeate the urine, and the detection unit can be localized as necessary. The size of the substrate 21 is, for example, 30 mm × 400 mm
It is about. The distal end portions of the strips 22 and 24 have wide portions 27 and 28 which are close to each other, and this portion serves as the above-described defecation / urination detection unit 33. In this example, the interval between the wide portions 27 and 28 is about 4 mm. This detector 3
The presence or absence of urination / defecation can be detected by detecting a change in the resistance value of No. 3 by a detection circuit (not shown).

Next, FIG. 4 shows an embodiment of a diaper pad according to the present invention. The diaper pad is used together with the diaper. In this embodiment, the diaper pad has a built-in sensor 20 for urination / defecation detection, but the sensor 20 is not essential.

The diaper pad 40 is formed by laminating two nonwoven fabrics 54 and 55, each of which is a water-absorbing cloth member, and binding the periphery thereof. The inner nonwoven fabric 54 has an opening 42 on one end surface similar to that of FIG. At the position of the opening 42, the stool guide member 41 is attached to both nonwoven fabrics 54 and 55.
Placed between.

FIG. 5 is a sectional view taken along the line V--V in FIG.
This stool guide member 41 has a different configuration from the stool guide member 5 of FIG.
Can also be used. However, in the case of the diaper pad, the existing diaper itself is used, so that it is difficult to secure a space for storing the diaper. Therefore, a configuration different from the stool guide member 5 is adopted here.

As can be seen from FIG.
Are arranged between the and 55 of the nonwoven fabric 54 such that the through holes 51 are aligned with the openings 42 of the nonwoven fabric 54.

FIG. 6 is a perspective view of a configuration example of the flight guide member 41. The stool guide member 41 includes an elastic base material (for example, made of styrene foam) 49 having a substantially convex cross-sectional shape, and a sponge 43 arranged so as to cover the convex portion. The sponge 43 has an opening corresponding to the through hole 51. The elastic base material 49 has a through hole 51 corresponding to this opening and extending in the vertical direction in the figure, as well as through holes 45 and 46 extending back and forth from the through hole 51 and through holes 47 and 48 extending left and right. Having. In this way, a stool storage space is secured inside the stool guide member 41 itself, and a larger stool storage space can be provided to both the nonwoven fabrics 5 by communicating with the outside.
4, 55 can be secured. The through holes 45, 46 corresponding to the direction along the spine of the body are thicker than the through holes 47, 48 at right angles thereto. This is through hole 4
This is because it is considered that a wider storage space can be secured on the outside on the side of the fifth and the 46th side.

In order to detect urination, at least the inner nonwoven fabric 54 must be formed of a water-absorbing material. However, when urination detection is not performed, both nonwoven fabrics 54 and 55 are formed of a waterproof sheet member. It is also possible.

When the diaper pad 40 is worn,
Unlike diapers, wear them prior to diapers. The manner of mounting is the same as in the case of the diaper in FIG. In this case, the diaper pad 40 is movable with respect to the diaper, but since the stool guide member 41 also has substantially the same elasticity as the stool guide member 5 in FIG. By having a gourd-shaped shape adapted to the crotch of the diaper wearer as shown in FIG. 4, the diaper pad 40 is prevented from being displaced.

Further, since the diaper is set in a state where the sensor 20 is extended to the outside of the diaper, this also contributes to the prevention of displacement of the diaper pad.

FIG. 7 shows the urination / urination used for the diaper pad 40.
2 shows a configuration example of a bowel movement sensor 20. This has been proposed by the present applicant in Japanese Patent Application No. 10-120047.
In this configuration, a short strip 23 is provided in parallel between the strips 22 and 24 in addition to the configuration shown in FIG. In the vicinity of the leading end 25 of the strip 23, a protrusion 26 protruding from the middle of the strip 24.
Is provided. The distal end portion 25 and the protruding portion 26 constitute a urination detecting unit 34. In this example, the distance between the distal end portion 25 and the projection portion 26 is about 20 mm. The detection unit 33 described above functions as a bowel movement detection unit. To expose the terminal part 31 at the end of the base member 21, the base part central part 30 including the urine detection part 34, and the stool detection part 33, and cover other parts.
The pattern 29 of the water-repellent ink is printed in a reverse U-shape. Thereby, the portion of the base material 21 of the pattern 29 does not permeate the urine, and it is possible to distinguish and detect urination and defecation.

The sensor 20 is mounted in the diaper pad so as to extend from the defecation part of the diaper wearer to the front of the diaper cover via the urine discharge part. The defecation detection unit 33 is arranged between the stool guide member 41 and the nonwoven fabric 55 at a position where the stool or its moisture reaches (in this example, a position corresponding to the through hole 51). However, the sensor 20 is not shown in FIG. Based on the position of the defecation detection unit 33, the urination detection unit 34 is located at a position away from the urination part of the care receiver in the longitudinal direction of the sensor 20.
The interval between the urination detection unit 34 and the defecation detection unit 33 is determined.

As described above, even if a small amount of urine is leaked and diffused by separating the urination detecting section from the urinating section by a predetermined distance, the water does not reach the detecting section 34 (of course, the detecting section 33). Not even reach). As a result, the detection output does not occur due to a small amount of urine leakage. When there is bowel movement, a detection output is generated by the detection unit 33 dedicated to bowel movement detection. Since the output of the detector 33 is generated independently of the output of the detector 34, defecation and urination are detected separately.

Although only the preferred embodiment of the present invention has been described above, various modifications and changes can be made without departing from the scope of the claims. For example, the present invention is not limited to the shape and material of each part as long as the same function and effect can be obtained.

[0037]

According to the present invention, the stool excreted in the diaper is prevented from adhering to the buttocks of the diaper wearer, so that the caregiver's labor can be saved and the burden on the diaper can be reduced. be able to. In addition, it is possible to prevent urinary tract infection in a diaper wearer and reduce the cause of diaper rash.
