Description

  The present invention relates to a diaper pad for washing and repeated use. In particular, the present invention relates to a diaper pad that is suitable for an adult who needs care such as an elderly person.

  In recent years, a diaper pad having a liquid absorbent pad core between a skin side sheet and an outer side sheet has been widely used as a cloth diaper pad that is repeatedly washed and used. A liquid-permeable fiber sheet that can transmit urine is used as the skin side sheet, and a liquid-permeable fiber sheet or a waterproof fiber sheet is used as the outer surface (outermost surface) sheet. Between these two sheets, a fabric such as a knitted fabric having a liquid absorptivity that absorbs urine and the like, and a nonwoven fabric (including a felt) is used as a liquid absorbent pad core (see Patent Document 1 below). In order to increase the liquid absorption amount, a liquid absorbent pad core is usually used as a pad core in which a plurality of knitted fabrics or nonwoven fabrics constituting these are laminated. Such a diaper pad is used with a diaper that is addressed to the skin side of the diaper.

  FIG. 16 is a plan view seen from the skin side of a typical example of such a conventional diaper pad, and FIG. 17 is an end view schematically showing the end surface of the AA ′ cross section of FIG.

The skin side sheet 161 is a liquid permeable fiber sheet that can permeate urine, and the outer side (outermost surface) sheet 162 is a liquid permeable fiber sheet or a waterproof fiber sheet. The two sheets are stitched together at the edge by a stitching line 166. Between the skin side sheet 161 and the outer side sheet 162, a plurality of fabrics 163 such as a knitted fabric and a non-woven fabric (which also includes felt) that absorb urine and the like are laminated and used as the liquid absorbent pad core 164. ing. The liquid-absorbent pad core 164 is stitched to the skin side sheet 161 while the plurality of fabrics 163 are stitched at the edge by a stitching line 165. This is to prevent the liquid-absorbent pad core 164 from moving inside to be unevenly distributed, twisted, or curled during processing in a washing machine or a dryer.

  For example, as shown in FIGS. 16 and 17, a conventional diaper pad has a relatively uniform thickness and a liquid-absorbing pad core disposed thereon, and the front core side pad core that is addressed to the front side of the human body. However, the amount and area of the pad core on the back body side that is addressed to the human body part side has not changed much between the front body side and the back body side. Although only the crotch is made slightly narrower, the amount and area occupied by the front core pad core and the back body pad core have not changed much between the front body side and the back body side.

  It is estimated that this may be because it was considered that it is not preferable to reduce the amount and area of the front pad core because urine may be released to the front side of the human body.

  However, according to the present inventors' various examinations of diaper pads, such as elderly people in need of nursing care, in nursing facilities, adults who need to wear diapers and diaper pads are bedridden elderly people It is known that there is a great deal of time in bed.

  And since the care recipient is usually laid on his back, when urinating in this state, the urine goes out to the front of the human body. Since it moves to the lower side, it has been found that a lot of urine accumulates on the buttocks side and the back side. However, in the conventional diaper pad, the amount and area of the pad core on the front body side and the pad core on the back body side have not changed much between the front body side and the back body side. However, the pad core could not absorb urine sufficiently, resulting in increased discomfort such as wetting and stickiness, and leakage of urine on the back waist side, that is, the back side.

  In addition, since such an adult requiring care is in a posture of sleeping for a long time, it is not particularly limited, for example, the apex of the rounded buttocks that bulge on the back side of the human body. Gravity is intensively applied to the part that protrudes outside the human body, such as in the vicinity, and the part is compressed, resulting in a state of pressure gangrene called “decubitus”, with great pain become. The conventional diaper pad has a problem that no special consideration is given to pressure distribution for reducing or preventing the occurrence of such pressure ulcers or alleviating the deterioration.

  The present invention solves the problems of such a conventional diaper pad, and even when urinating in a sleeping state with a relatively large number of usage modes, the urine is sufficiently absorbed even on the buttocks side, so that it feels wet and is sticky. Reducing the wearer's discomfort such as feeling, preventing further urine leaking in the back waist direction, and the part where the human body swells, etc. An object of the present invention is to provide a pad for a diaper having a good wearing feeling, which can reduce or prevent the occurrence of pressure ulcers in the areas where pressure ulcers tend to occur, and also reduce the deterioration.

  In order to solve the above problems, the diaper pad of the present invention is a diaper pad that has a liquid-absorbent pad core between the skin side sheet and the outer side sheet, and is applied from the lower abdomen to the crotch and the buttocks. The area and amount (weight) of the pad core arranged in the back body are larger than the area and amount of the pad core arranged in the front body, and above the left and right bulge parts of the human body hip part and the right and left bulge parts of the buttock part. The upper part in the middle is a diaper pad in which the pad core is thicker than the thickness of the pad core in the portion where the left and right bulge portions of the buttock are in contact with each other.

  In the diaper pad according to the present invention, the area and amount of the pad core disposed on the rear side are larger than the area and amount of the pad core disposed on the front side. Is sufficiently absorbed even on the buttock side, reducing the wearer's discomfort such as a wet feeling and stickiness, and further preventing urine from leaking in the rear waist direction. In addition, since the area and amount of the pad core disposed on the front side are smaller than those on the rear side, the feeling of pressure on the abdomen is reduced and the wearing feeling is improved.

  Moreover, the upper part of the upper and lower left and right bulge parts of the human body buttock and the upper part between the left and right bulge parts of the buttock are used as a pad core whose thickness is thicker than the thickness of the pad core at the part where the left and right bulge parts of the buttock abut. Therefore, it distributes the concentration of pressure on the swollen buttocks of the human body, which is subject to pressure in the bed, to reduce or prevent pressure ulcers from occurring in areas where pressure ulcers tend to occur, and to mitigate the deterioration. It is possible to provide a diaper pad having a good wearing feeling that also has the above.

  (1) The diaper pad of the present invention is a diaper pad that has a liquid-absorbent pad core between the skin side sheet and the outer side sheet and is applied from the lower abdomen to the crotch and hips, and is arranged in the back body. The area and amount of the pad core to be applied are larger than the area and amount of the pad core arranged in the front body, and the upper part between the left and right bulge portions of the human body buttock and the upper part between the left and right bulge portions of the buttock are The diaper pad has a pad core whose thickness is thicker than the thickness of the pad core at the portion where the left and right bulge portions of the buttock are in contact.

  (2) In the diaper pad according to (1), the thickness of the pad core is preferably adjusted by the number of stacked sheet-like pad core pieces that form the pad core.

  Creating a pad core in which the thickness of the pad core is changed depending on the site is considerably troublesome to manufacture and increases the cost. For example, a portion to be thickened is desired depending on the shape of the portion to be thickened. By stacking a plurality of sheet-shaped pad core pieces cut into a shape, the thickness can be easily adjusted, and the pad core piece has a size and shape suitable for the shape of the portion to be thickened. Can be easily manufactured by cutting a pad core base fabric such as felt into a desired shape and size, so that it is easy to manufacture and can be manufactured at a relatively low cost.

  (3) Moreover, in the diaper pad according to any one of (1) to (2), the amount of the pad core disposed in the back body of the diaper pad is the amount of the pad core disposed in the front body. It is preferably 2 to 5 times (weight ratio).

  Since the amount of the pad core disposed on the rear side is larger as described above than the amount of the pad core disposed on the front side, even when urinating while sleeping, urine is sufficiently absorbed even on the buttocks side. It is possible to reduce the wearer's discomfort such as a wet feeling and a sticky feeling, and further prevent urine from leaking to the back side above the back waist. Moreover, since the amount of pad cores arranged on the front side is smaller than those on the rear side, the feeling of pressure on the abdomen is less and the wearing feeling is further improved.

  (4) Moreover, in the diaper pad according to any one of the above items (1) to (3), the pad core disposed on the back body of the diaper pad is wide and disposed from the crotch part to the front body part. It is preferable that the width of the pad core to be formed is narrower than the width of the pad core disposed in the back body.

Since the width of the pad core disposed on the rear side is wide, even when urinating while sleeping, urine is sufficiently absorbed even on the buttock side, and leakage of urine can be further prevented. In addition, since the width of the pad core disposed on the crotch part and the front side is narrower than the width on the rear side, the feeling of pressure on the abdomen is less and the wearing feeling is further improved.
(5) Moreover, in the diaper pad according to any one of the above items (1) to (4), the skin side sheet is made of a liquid-permeable fiber knitted sheet that can transmit urine, and the outer side sheet is urine. It is preferably made of a waterproof fiber knitted sheet that hardly permeates.

  By making the skin side sheet into a liquid-permeable fiber knitted sheet that can permeate urine, the waterproof fiber knitted fabric that can easily guide urine to the absorbent pad core and hardly allow urine to permeate through the outer side sheet. By using a sheet, the function of preventing urine absorbed in the pad core from leaking to the outside can be exhibited, which is preferable.

  (6) In the diaper pad according to any one of (1) to (5), the skin side surface sheet and the pad core pass through the crotch part from the front body part about the center in the width direction of the pad core. It is preferable to have a center groove in the form of a suture line formed by sewing with a sewing line reaching the lower part of the back body.

  When urinating, urine passes through the skin side sheet and is absorbed by the pad core, but it takes some time to pass through the skin side sheet. Therefore, urine tends to disperse in an indiscriminate direction on the skin side sheet, and urine may leak out of the diaper pad.

  The stitching line forms a groove by stitching the skin side sheet and the pad core together with a sewing line that extends from the front body part to the lower part of the rear body through the crotch part from the front body part to the center of the pad core in the width direction. Therefore, urine can easily flow along the groove, and the absorption direction of urine can be easily guided to the back body side along the length direction of the pad core. Since the urine is open, it is easier for urine to enter the pad core from the groove portion, and the time taken to pass through the skin side sheet and led to the pad core can be shortened, thereby further preventing urine from leaking to the outside. ,preferable.

  (7) Moreover, in the diaper pad according to any one of (1) to (6) above, the skin side sheet and the pad core are placed on the left and right sides of the back side of the pad core on the back side of the pad core. It is preferable to have left and right grooves in the form of left and right stitching lines formed by stitching with a sewing line that extends from the side to the middle and reaches the middle of the upper edge of the back body.

  The left and right grooves made up of the suture lines make it easier to guide the urine flowing from the front side to the rear side along the left and right grooves made up of the left and right suture lines while sleeping. Since the urine is passed and the hole is opened, the urine that has flowed can be easily absorbed into the pad core, and the urine can be reliably guided to the pad core on the rear side, which is preferable because leakage of urine to the outside can be reduced.

  (8) Moreover, in the diaper pad according to any one of the above items (1) to (7), the upper edge of the front body of the diaper pad is placed at the position of the navel or 10 cm below it. It is preferable to have a length to be measured.

  In adults who need to be bedridden, as described above, when urinating while sleeping, the urine moves downward due to gravity, so eventually a large amount of urine accumulates on the buttocks side and back side. Cheap. Therefore, the diaper pad on the front side does not need to cover the front side of the human body with such a large area and large capacity, and the upper edge of the front body of the diaper pad is placed at the position of the navel or 10 cm below it. As long as it has sufficient thickness, it is sufficient, and as a result, the feeling of pressure on the abdomen can be reduced and the wearing feeling is improved.

  (9) Moreover, in the diaper pad according to any one of the above items (1) to (8), the front body of the diaper pad core preferably has a size that covers the male genitals.

  In adults who need to be bedridden, as described above, when urinating while sleeping, the urine moves downward due to gravity, so eventually a large amount of urine accumulates on the buttocks side and back side. Cheap. Therefore, the front diaper pad core does not need to cover the front side of the human body with such a large area and large capacity. The diaper pad of the present invention can be used for both men and women, but the male genitals protrude outward from the human body compared to the female genitals, and the volume of the part protruding outwards increases. Therefore, if the front part of the diaper pad core is large enough to cover the male genitals, there will be no problems such as leakage of urine even if worn by women. By making the size of the front side portion of the diaper pad core as described above, the feeling of pressure on the abdomen can be reduced and the wearing feeling is improved.

  (10) Moreover, in the diaper pad according to any one of the above items (1) to (9), the area of the appearance of the front body of the diaper pad is preferably smaller than the area of the appearance of the back body. .

  In hospitals and elderly care facilities, a large amount of diapers are washed and dried with a dryer. Normally, diaper pads are provided with rubber tape on the edges of the left and right sides of the crotch part or appropriate gathers so that the front and back of the diaper are warped to the skin. In many cases, the front body and the back body are bent toward the skin centering on the crotch, and the front body and the back body often overlap. At this time, if the area of the front body and the back body is almost equal, it will be difficult to dry the overlapping part of the front body and back body, it will take time to dry, large quantities of diapers such as hospitals and elderly care facilities Time and cost are considerably increased when they must be washed and dried. However, the area of the front body of the diaper is smaller than the area of the back body, so the area of the front body and the back body is different. This is preferable because it can save considerable time and cost. Moreover, since the front body is small, even when it overlaps with the back body, the front body easily moves when rotating in the dryer, and the overlapping position often changes, so that drying becomes easy.

  (11) Moreover, in the diaper pad according to any one of the above items (1) to (10), the area of the appearance of the front body of the diaper pad is 70 to 50% of the area of the appearance of the back body. Preferably there is. If the area of the front body is too small, urine is likely to leak from the front side during urination, so the area of the appearance of the front body of the diaper pad is in the range of 70 to 50% of the area of the appearance of the back body. This prevents the urine from leaking easily from the front side during urination, while the areas of the front body and the back body described in the above section (10) are different. This is preferable because it can save considerable drying time and cost.

(12) Moreover, in the diaper pad according to any one of (1) to (11), the thickness of the diaper pad core is adjusted by the number of stacked sheet-like pad core pieces forming the pad core. A diaper pad core,
The pad core rear body is wide to cover the buttocks, the pad core front body reaches a position that can cover the male genitals, and the crotch to the upper edge of the front body can cover at least the male genitals Having a first base pad core piece that is narrower in width than the back of the pad core,
In order to increase the thickness of the pad core on the skin side from the first base pad core piece, a convex downward is directed over the left and right bulge portions of the human body buttock and over the upper part between the left and right bulge portions of the heel portion. It is preferable that the collar part upper 1st pad core piece which has a planar shape is laminated | stacked.

  The width of the back body of the pad core is large and the width of the front body is preferably small, as described in the above section (4), and when worn by making the width of the crotch part smaller than the width of the back body of the pad core. Moreover, it becomes easy to fit in a crotch part and a feeling of wear also becomes favorable and is preferable.

  14 and 15 show a side view from the vicinity of the waist of the human body to the vicinity of the thigh and a perspective view as seen from the rear side. In FIG. 15, a dotted line 150 schematically shows the center line on the rear side of the human body, and dotted lines 151a and 151b are simulation lines that are entered to clearly show that the buttock bulges outward.

  The portion of the upper portion 152 between the left and right bulge portions of the heel portion corresponding to the vicinity of the upper edge of the portion to which the pad for diapers of the present invention is applied is compared with the bulge portion of the buttock portion. It is depressed. In such a portion, a pad core piece (a first pad core piece of the heel portion upper portion) (for example, see FIG. 7) having a downwardly convex planar shape is laminated on the skin side from the first base pad core (for example, see FIG. 9). This can not only increase the amount of urine absorbed on the back body side, but also increase the thickness of the pad core addressed to the recessed part of the human body, and therefore the heel of the human body, which is prone to pressure on the bed A diaper pad that is comfortable to wear even in a sleeping state that distributes the concentration of pressure on the part, etc., reduces or prevents the occurrence of pressure ulcers in areas where pressure ulcers tend to occur, and also reduces the deterioration Can be provided.

  In addition, the pad core piece having the size and shape suitable for the shape of the portion to be thickened can be easily manufactured by cutting the pad core base fabric into the desired shape and size, so it is easy to manufacture and costs Can be manufactured relatively inexpensively.

  (13) Moreover, in the diaper pad according to the above (12), the first base pad core part is formed on the outer surface of the first base pad core part piece except for at least the left and right widths of the upper edge of the back body. It is preferable that a second base pad core piece having a width narrower than the piece and having a length shorter than the upper edge of the first base pad core piece is shorter than the upper edge of the front body.

  By laminating the second base pad core piece (see, for example, FIG. 10), the liquid absorption amount of the diaper pad can be increased and leakage of urine can be further prevented. 1 Base pad core piece (for example, see FIG. 9) is narrower than the first base pad core piece and shorter than the upper edge of the rear body and the upper part of the front body. In addition, the pad core does not become thick, and the feeling of pressure on the abdomen can be reduced and the wearing feeling can be kept good. The width of the second base pad core piece is narrower than that of the first base pad core piece, so that when the width is the same, the edges become stiff, and in particular, the crotch slippage may occur at the crotch or the like. Can be prevented, and the fit and wear feeling can be improved.

  (14) Moreover, in the diaper pad according to any one of the above items (12) to (13), the first base pad core piece on the back body is positioned closer to the skin than the first base pad core piece. It is preferable that a strip core-like upper edge thickness increasing pad core piece is further laminated along the edge.

  In the position closer to the skin than the first base pad core piece (for example, see FIG. 9), along the upper edge of the first base pad core piece, the upper edge of the back body of the narrow strip, (See, for example, FIG. 6) can further prevent urine from leaking in the back direction of the back side, and can increase the thickness of the pad core addressed to the recessed portion of the human body. A bed that disperses the concentration of pressure on the inflatable buttocks of the human body, which is subject to pressure in the bed, to reduce or prevent the occurrence of pressure ulcers in areas where pressure ulcers tend to occur, and to reduce the deterioration It is possible to provide a diaper pad having a good wearing feeling even in a worn state.

  (15) Moreover, in the diaper pad according to any one of the above (12) to (14), the heel portion is provided between the skin side surface of the first base pad core piece and the heel upper first pad core piece. The upper base pad core piece is approximately the same size as the first base pad core piece or the heel upper first pad core piece and the upper edge thereof is at the same position or slightly below the upper part. There is further provided a second pad core piece having an irregular elliptical shape that protrudes to the left and right sides of the projecting protrusion below the first pad core piece, and whose lower edge passes through a portion shorter than the tip of the projecting protrusion. It is preferable that they are laminated.

  Between the skin side surface of the first base pad core piece (for example, see FIG. 9) and the heel upper first pad core piece (for example, see FIG. 7), the above-mentioned buttock upper second pad core piece (see, for example, FIG. 8). Is further laminated, the thickness of the pad core gradually increases in the vicinity of the upper part of the bulges of the left and right buttocks along the part where the dent of the human body gradually increases toward the upper part of the rear center. Therefore, it is possible to increase the thickness of the pad core addressed to the depressed part of the human body, and thus to more easily disperse the concentration of pressure on the bulging part of the human body where pressure is easily applied to the bed. The occurrence of pressure ulcers that tend to occur can be reduced or prevented, and the deterioration thereof can be alleviated, and a diaper pad having a good wearing feeling even when lying down can be provided. Moreover, because the heel part upper second pad core piece is further laminated, the amount of urine absorbed on the back body side can be further increased, leakage of urine can be further prevented, and diapers with good wearing feeling with reduced stickiness Can provide a pad.

  (16) Moreover, in the diaper pad according to any one of (1) to (15), the thickness of the diaper pad core is adjusted by the number of stacked sheet-like pad core pieces forming the pad core. A pad core for a diaper, in which three or more pad core pieces are stacked and used, and the edge of the rear body of the three or more pad core pieces that faces in the lateral direction of the human body It is preferable that the edge of the at least one piece of the pad core pieces that faces in the lateral direction of the human body is left in a free state without stitching with the other pad core pieces.

  The upper edge of the back of the pad core of the diaper pad takes weight when sleeping, so if the feel of that part is hard, the feeling of wearing will decrease, and for example, 3 or more pad core pieces made of felt etc. If the stitches are overlapped, the flexibility and flexibility of the stitched portion are reduced, and it becomes difficult to follow the three-dimensional curved surface of the human body. Therefore, in such a case, the edge of the at least one piece that faces in the lateral direction of the human body is kept in a free state without being sewn with other pad core pieces, thereby maintaining the flexibility of this portion. In addition, it is preferable because the fitting property to the three-dimensional curved surface of the human body can be kept good and the wearing feeling can be improved.

  (17) Moreover, in the diaper pad according to any one of (1) to (16), a liquid damming piece made of a waterproof cloth along the upper edge of the back side of the skin side surface of the skin side sheet. Is preferably further provided.

  By providing a liquid damming piece made of waterproof cloth along the upper edge of the back body, it is possible to prevent urine from leaking to the back side even when the pad core on the back body cannot fully absorb urine. preferable.

  (18) Moreover, in the diaper pad according to any one of the above items (1) to (17), a waterproof cloth is provided on at least the peripheral edge of the back body of the diaper pad and the edge of the crotch part in contact with the thigh. It is preferable that a piping margin fabric made of is attached.

  When urinating while sleeping, the amount of urine absorbed and retained increases especially at the crotch where it touches the back and thighs. By attaching a piping brim made of waterproof cloth, it is possible to prevent urine from leaking from the edge of the crotch that touches the back body and thigh, which absorbs a lot of urine while sleeping. This is preferable.

  Piping means a method in which the edge of a cloth is wrapped with another cloth and stitched.

  Hereinafter, in order to facilitate understanding of the present invention, typical diaper pads of the present invention will be described with reference to the drawings. The diaper pad of the present invention is not limited to those shown in these drawings.

FIG. 12 is a plan view of a diaper pad according to an embodiment of the present invention as viewed from the side of the skin, in which the positions of the pieces arranged inside are overlapped and displayed (however, a liquid damming piece made of waterproof cloth) And piping rims not shown). FIG. 13 is an end view schematically showing the end surface of the diaper pad according to the embodiment of the present invention shown in FIG.

  FIGS. 4 to 11 are views showing each piece for each piece, and FIGS. 1, 2, 12, and 13 are drawings suitable for understanding the state in which these pieces are combined.

  Accordingly, the following description of the specific embodiments of the present invention is based on the premise that all of these drawings are referred to, and thus will be described without quoting the drawing numbers. The drawing number may be quoted. However, it does not mean that reference to other drawings is unnecessary.

  The diaper pad according to an embodiment of the present invention has a liquid-absorbing pad core that absorbs and holds urine between the skin side sheet 1 and the outer side sheet 2 as shown in FIG. Is formed from a plurality of sheet-like liquid-absorbing pad core pieces 3, 4, 5, 6, and 7.

  The skin side sheet 1 is a knitted fabric or woven fabric that can transmit urine, and is not particularly limited. However, a liquid-permeable fiber knitted sheet that can transmit urine is suitable. For example, a tricot knitted fabric or the like is used. . As the material fiber used for the skin side sheet 1, various fibers can be used as long as it is a knitted or woven fabric that can transmit urine, and is not particularly limited. For example, polyester fiber, acrylic fiber, cotton Etc. are suitable. Of course, there is no problem in using these together, or using a fiber that has been subjected to antistatic processing or a fiber that has been imparted with antibacterial and deodorizing properties.

  As the outer surface sheet 2, a waterproof cloth is used, and preferably a waterproof knitted fabric having stretchability is used. Although it does not specifically limit as a knitted fabric, A tricot etc. are suitable. The material fiber used for the outer sheet 2 is not particularly limited, and examples thereof include polyester fiber, acrylic fiber, and polypropylene fiber. As the waterproof treatment, a waterproof resin treatment, for example, a normal waterproof treatment such as a treatment with a fluororesin, a silicone resin treatment, a polyurethane resin treatment, or the like can be employed.

  As apparent from FIGS. 5 and 11, the skin side sheet 1 and the outer side sheet 2 have substantially the same planar shape, and the area of the appearance of the front body X is the back body Z. Those having an area smaller than that of the external appearance are used. Y indicates the crotch. The back body Z is addressed to the buttocks on the back side of the human body and has a relatively large area. The width from the crotch Y to the front body X is narrow. The lengths of the skin side sheet 1 and the outer side sheet 2 are not particularly limited, but the upper edge portions 1a, 2a of the front body are assigned to the position of the navel or 10 cm below the upper body, The edges 1b and 2b are preferably long enough to reach a position of 3 to 10 cm below the waist constriction.

  In adults who need to be bedridden, as described above, when urinating while sleeping, the urine moves downward due to gravity, so eventually a large amount of urine accumulates on the buttocks side and back side. Cheap. Therefore, the front diaper pad does not need to cover the front side of the human body with such a large area, and has a length in which the upper edge of the front body of the diaper pad is applied to the position of the navel or 10 cm below it. Anything is sufficient, and as a result, the feeling of pressure on the abdomen can be reduced and the wearing feeling is improved.

  As the pad core, a nonwoven fabric (meaning including felt), a knitted fabric, a woven fabric, or the like is used, and a nonwoven fabric (felt) is particularly preferable. A knitted fabric, a woven fabric, or the like may be used. To increase the thickness, the number of laminated layers may be increased, or a double woven fabric, a triple woven fabric, or the like may be used. Examples of the fiber material constituting the pad core include polyester fibers, polyacryl fibers, polyamide fibers, regenerated cellulose fibers, various fibers such as cotton and wool, and combinations thereof.

  As will be described later, as the diaper pad of the present invention, the area and amount (weight) of the pad core disposed in the back body is larger than the area and amount of the pad core disposed in the front body, and The upper part of the upper part between the right and left bulge parts and the upper part between the right and left bulge parts of the buttock is such that the pad core is thicker than the pad core thickness of the part where the left and right bulge parts of the buttock are in contact with each other. Depending on the part to which it is assigned, a pad core whose thickness is changed is used, but creating a pad core with the thickness of the pad core changed according to the part is considerably troublesome to manufacture and also increases costs. For example, laminating a plurality of sheet-like pad core pieces that are cut into a desired shape according to the shape of the portion to be thickened, etc. More, it is preferable to adjust the number of stacked Paddokoa piece made of felt to form a Paddokoa a thickness of Paddokoa. Moreover, when using a plurality of pad core pieces, the thickness of each pad core piece is not particularly limited, but a thickness of about 2 to 7 mm, more preferably about 3 to 6 mm is used. preferable. In addition, when laminating a plurality of pad core pieces, the apparent density of each pad core piece may be the same, but if the apparent density is small and the large one is alternately laminated, Phenomena such as urine absorbed in the pad core returning from the inside of the pad core to the surface side can be prevented, which is preferable. The one with a small apparent density has a high urine absorption rate, and the one with a large apparent density has a large ability to hold urine inside. Thus, the thickness of the pad core is reduced to a sheet-like pad core made of felt or the like. A method of adjusting according to the number of laminated pieces is preferable because it is possible to alternately use pad core pieces having a low apparent density and pad core pieces having a high apparent density.

  Next, the pad core piece disposed between the skin side sheet 1 and the outer side sheet 2 in the present embodiment will be described. First, as the basic first base pad core piece 6, the back body Z is wide to cover the buttocks, and the pad core front body X has reached a position that can cover the male genitals, The first base pad core piece 6 that is narrower than the pad core rear body Z in a range where the crotch Y to the upper edge 6a of the front body can cover at least the male genitals (FIGS. 13, 12, and 9). Reference) is provided. Although it does not specifically limit, the position of the upper edge 6b of the back body is slightly lower than the rear edge upper edges 1b and 2b of the skin side sheet 1 and the outer side sheet 2 (for example, about 0.7 to 1.5 cm below). Side) is preferable (see FIGS. 12 and 13). That is, when the pad core does not exist until reaching the peripheral edges of the skin side sheet 1 and the outer side sheet 2, the peripheral edge of the diaper pad can be made flexible, and the diaper pad is placed on the diaper. When it is worn together, the peripheral portion of the diaper pad is easy to fit on the skin, and it is preferable from the viewpoint that a gap is hardly formed between the skin and the diaper pad. The same applies to the side, and the width of the first base pad core piece 6 is preferably narrower than the width of the skin side sheet 1 and the outer side sheet 2. Depending on the part, for example, the width of the back body Z is about 2 to 6 cm in total on the left and right sides, and the width of the crotch Y and the front body X is about 6 to 10 cm in total on the left and right sides. 2 is preferably narrower than the width of the corresponding part. In addition, the numerical values of the other pad core pieces are also different, but similarly, it is more flexible if the pad core does not exist until reaching the peripheral edges of the skin side sheet 1 and the outer side sheet 2. When the diaper pad is placed on the diaper and worn with the diaper, the peripheral part of the diaper pad is preferable because it easily fits the skin. In FIG. 1, FIG. 13, etc., reference numeral 26 denotes a stitching line between the front body upper edge portion 6 a and the left and right edge portions 6 d of the first base pad core piece 6 and the skin side sheet 1.

  Next, the collar upper first pad core piece 4 (see FIGS. 7 and 12) will be described. In this embodiment, the buttock upper first pad core piece 4 is laminated on the above-described first base pad core piece 6 via a buttock upper second pad core piece 5 described later (FIG. 13). reference).

  The buttocks upper first pad core piece 4 is a pad core piece having a downwardly convex planar shape that is directed over the upper part between the left and right bulge parts of the human body buttock and the upper part between the left and right bulge parts of the buttock. As described with reference to FIG. 15, the upper part 152 between the left and right bulging parts of the human body buttock and the upper part 152 between the left and right bulging parts of the buttock corresponding to the vicinity of the upper edge of the part to which the diaper pad of the present invention is addressed This part is recessed compared with the bulge part of the buttocks. For example, as shown in an example of a position addressed by a one-dot chain line 153 in FIG. 15, the upper part of the first pad core part of the heel portion having a downwardly convex planar shape (a downwardly protruding protrusion 4d). 4 is further addressed, so that not only can the amount of urine absorbed on the back body side be further increased, but also the thickness of the pad core addressed to the recessed part of the human body can be increased, and thus the human body that is easily subjected to pressure in the bed Disperses the concentration of pressure on the swollen buttocks, etc., and can help to exert functions such as reducing or preventing the occurrence of pressure ulcers in areas where pressure ulcers are prone to occur, and alleviating their deterioration .

  In the present embodiment, the heel upper second pad core piece 5 is further laminated between the skin side surface of the first base pad core piece 6 and the heel upper first pad core piece 4 (FIG. 8, FIG. 12, FIG. 13). The position of the upper edge 5b of the heel upper second pad core piece 5 is slightly lower than the upper edge 6b of the rear body of the first base pad core piece 6 and the upper edge 4b of the heel upper first pad core piece 4. (See FIG. 13). Accordingly, the upper edges of the first base pad core piece 6, the heel upper first pad core piece 4, and the heel upper second pad core piece 5 are not sewn simultaneously, and the first base pad core piece 6 is not sewn at the same time. The upper edge 6b and the upper edge 4b of the buttock upper part first pad core piece 4 are stitched together by the stitching line 21, and the upper edge 5b of the buttock upper second pad core piece 5 remains a free edge. This is because if the above three edges are sewn at the same time, the stitched portion becomes stiff, but the upper edge of the buttock upper second pad core piece 5 is not sewn at the same time, but remains as a free edge. By this, the softness | flexibility of this part is maintained and a feeling of wear can be made favorable. The other edges of the part where all three members overlap are sewn together, and the other edge of the upper part of the second pad core piece 5 of the buttock upper part is the edge of the part where the three members do not overlap, The first base pad core piece 6 is stitched to the first base pad core piece 6 (a part of the stitching line is indicated by reference numeral 23 in FIG. 13). 1 The base pad core piece 6 and the buttock upper second pad core piece 5 are stitched together (a part of the stitching line is indicated by reference numeral 24 in FIG. 13).

  The buttocks upper second pad core piece 5 has a size that is substantially similar to the buttocks upper first pad core piece 4 (the area is slightly larger than the buttocks upper first pad core piece 4). The shape is slightly different from that of the first pad core piece 4, and the left and right edge portions 5 c on the lower side of the collar upper second pad core piece 5 are located on the left and right sides of the projecting portion 4 d that protrudes downward in the collar pad upper first pad core piece 4. It protrudes outward from the edge 4c. Moreover, the lower edge 5a of the heel upper second pad core piece 5 passes through a portion (inner portion) shorter than the tip 4a of the protrusion 4d of the heel upper first pad core piece 4 so that the overall planar shape is As shown in FIG. 8, it has an irregular substantially elliptical shape.

  By further laminating the buttock upper second pad core piece 5 between the skin side surface of the first base pad core piece 6 and the heel upper first pad core piece 4, the upper vicinity of the swelling of the left and right buttock In the portion, the portion where only the first base pad core piece 6 is provided as shown in FIG. 12 with respect to the portion (see FIGS. 14 and 15) in which the hollow of the human body gradually increases obliquely above the rear center portion, A portion where the first base pad core piece 6 and the buttock upper second pad core piece 5 overlap, a first base pad core piece 6, a buttock upper second pad core piece 5, and a buttock upper first pad core piece 4. Since the thickness of the pad core is gradually increased, such as where the three members overlap, the thickness of the pad core addressed to the recessed portion of the human body can be increased in a state that is more in line with the shape of the human body. Sleeping Therefore, it is easier to disperse the concentration of pressure on the inflatable buttocks of the human body that are subject to pressure in the bed, to reduce or prevent the occurrence of pressure sores in the areas where pressure ulcers tend to occur, and to reduce the deterioration Is even easier to do. Moreover, the buttock upper second pad core piece 5 is further laminated, so that the amount of urine absorbed on the back body side can be further increased, urine leakage can be further prevented, the feeling of stickiness is reduced, and the wearing feeling is improved. obtain.

  In the present embodiment, the upper edge of the strip-like back body along the upper edge 4b of the upper heel part first pad core piece 4 at a further skin side position of the heel upper first pad core part 4 A part thickness increasing pad core piece 3 (see FIGS. 6, 12, and 13) is further laminated. The lower edge 3 a of the pad core piece 3 is substantially linear, and the upper edge 3 b has the same shape as the upper edge 4 b of the upper heel part first pad core piece 4. This pad core piece 3 is sewn to the upper buttock first pad core piece 4 along the lower edge 3 a by a stitching line 22. The upper edge 3b of the pad core piece 3 is left free without being sewn with other pad pieces. By carrying out like this, the softness | flexibility of this part can be hold | maintained and a wear feeling can be made favorable. If this part is also sewn, this part becomes hard and it is preferable because it is difficult to bend freely and the problem that the feeling of wearing is lowered is prevented.

  By further laminating the back core upper edge thickness increasing pad core piece 3, it is possible to further prevent urine from leaking in the back direction of the back side, and further, the pad core addressed to the recessed part of the human body The thickness can be increased, and therefore the concentration of pressure on the inflatable buttocks of the human body, which is subject to pressure in the bed, is distributed, reducing or preventing the occurrence of pressure ulcers in areas where pressure ulcers are likely to occur, and mitigating their deterioration The function to perform becomes easier. Therefore, it is possible to provide a diaper pad that has a good wearing feeling even when lying down.

  In the present embodiment, the second base pad core piece 7 is further laminated on the outer surface of the first base pad core piece 6 (see FIGS. 10, 12, and 13).

  The second base pad core piece 7 is narrower than the first base pad core piece except for the left and right widths of the upper edge 7b of the back body, and the length is also on the back body of the first base pad core piece 6. It is shorter than the edge 6b and the upper edge 6a of the front body (see FIGS. 12 and 13). In FIG. 10, 7 a indicates the upper edge of the front body of the second base pad core piece 7. Reference numeral 7 d denotes left and right side edges of the second base pad core piece 7.

  Since the second base pad core piece 7 is narrower than the first base pad core piece 6 and is shorter than the upper back edge 6b of the first base pad core piece 6 and the upper edge 6a of the front body, At the upper edge of the front body, the pad core is not unnecessarily thick, and the feeling of pressure on the abdomen can be reduced and the wearing feeling can be kept good. By making the width of the second base pad core piece 7 narrower than that of the first base pad core piece, if the width is the same, the edges become stiff, and crotch slippage tends to occur particularly in the crotch. It is preferable because it can prevent the wear feeling from being lowered and improve the fit and wear feeling. Moreover, the amount of urine absorbed can be increased by the presence of the second base pad core piece 7. The second base pad core piece 7 is stitched to the first base pad core piece 6 along the left and right edges and the upper edge 7a of the front body (the stitching line 25 in FIG. The suture line is shown.) The upper edge 7b of the back body of the second base pad core piece 7 is free without being sewn with other pad pieces. By doing in this way, the softness | flexibility of this part is hold | maintained and a feeling of wear can be made favorable. If this part is also sewn, this part becomes hard and it is preferable because it is difficult to bend freely and the problem that the feeling of wearing is lowered is prevented.

  Thus, when the pad core formed by laminating the pad core pieces is viewed as a whole, the left and right edges 6d and 6d of the first base pad core piece 6 and the front body upper edge 6a are the other pad cores. Since this part consists of a single pad core piece that protrudes from the edge of the piece, when the diaper pad of this embodiment is worn, these peripheral parts are soft, so it is easy to follow the three-dimensional shape of the human body and improve fit It is preferable because the feeling of wearing can be kept good.

  Further, in the diaper pad according to the present embodiment, a liquid damming piece 8 made of a waterproof cloth is further provided along the upper edge of the back side of the skin side surface of the skin side sheet 1 (FIG. 1). (Refer FIG. 13, FIG. 4). The shape of the cloth before the liquid damming piece 8 is attached is not particularly limited, but may be a long and narrow rectangular cloth as shown in FIG. Of course, a long crescent-shaped dough may be used. Even when an elongated rectangular fabric is used, it may be shaped as shown by the liquid damming piece 8 in FIG. As is clear from the cross-sectional shape of the liquid damming piece 8 in FIG. 13, the widthwise cross-section is swelled so as to swell upward (sewing lines 20 and 28). By doing so, a dam-like weir is formed with a waterproof cloth, and even when the pad core in the back body cannot fully absorb urine, the function of preventing the urine from leaking to the back side can be exhibited, which is preferable. .

  Further, in the diaper pad of the present embodiment, a waterproof cloth is applied to the edge of the crotch part Y in contact with the peripheral edge and the thigh of the back body Z of the skin side sheet 1 and the outer side sheet 2 of the diaper pad. Piping edge fabrics 9 and 10 are attached (see FIGS. 1, 2 and 13). In this embodiment, the peripheral edges of the front body X of the skin side sheet 1 and the outer side sheet 2 of the diaper pad are stitched by the stitching line 27 without using the piping margin cloth. A piping margin fabric may be attached accordingly. Reference numeral 20 in FIG. 13 indicates a stitching line in which the piping edge fabric is stitched to the edges around the back body Y of the skin side sheet 1 and the outer side sheet 2.

  When urinating while sleeping, the amount of urine absorbed and retained increases especially at the crotch where it touches the back and thighs. By attaching a piping brim made of waterproof cloth, it is possible to prevent urine from leaking from the edge of the crotch that touches the back body and thigh, which absorbs a lot of urine while sleeping. This is preferable.

  Furthermore, in the diaper pad of the present embodiment, as shown in FIG. 1, a piping margin cloth 10 made of a waterproof cloth is provided along the skin side of the crotch edge that contacts the thigh of the skin side sheet 1 of the diaper pad. Although not shown, an elastic tape such as a rubber tape is attached to the inside. Reference numeral 40 denotes a gather. By doing in this way, the periphery edge of the crotch part of a diaper pad fits a wearer's thigh closely, and it can prevent the leakage of urine, and is preferable.

  Furthermore, in the diaper pad of the present embodiment, as shown in FIGS. 1 and 12, the skin side surface sheet and the pad core pass through the crotch Y from the front body portion through the center in the width direction of the pad core. It has a center groove 30 in the shape of a stitching line formed by sewing with a sewing line reaching the lower part of the back body X, and further lowers the back body of the pad core on the left and right sides of the back body Z of the pad core. It has left and right stitches 31a and 31b in the form of left and right stitching lines formed by stitching with a sewing line that extends from the side upward and reaches the middle of the upper edge of the back body.

  When urination is performed, urine passes through the skin side sheet 1 and is absorbed by the pad core, but it takes some time to pass through the skin side sheet 1. Therefore, urine tends to disperse in an indiscriminate direction on the skin side sheet, and urine may leak out of the diaper pad.

  By stitching the skin side surface sheet 1 and the pad core as described above, the stitching line forms a groove, so that urine can easily flow along the central groove 30, and the urine absorption direction is defined by the length direction of the pad core. The groove can be easily guided to the back body side, and since the perforation is perforated through a sewing needle when sewing, urine can easily enter the pad core from the groove, Since the time for passing through the side sheet and being guided to the pad core can be shortened, leakage of urine to the outside can be further prevented. Further, the left and right grooves 31a and 31b formed by the stitching lines are sewn to the left and right grooves 31a and 31b when the urine flowing along the central groove 30 from the front side to the rear side spreads to the large back body pad core. It is easy to guide along the left and right grooves composed of lines, and it is preferable that urine can easily enter into the pad core of the back body with a large area from the groove part, can be easily absorbed by the pad core, and leakage of urine to the outside can be reduced. .

  As described above, in the diaper pad in the present embodiment, the pad core pieces are appropriately stacked, and the thickness and amount (weight) of the diaper pad core of a predetermined portion are adjusted to a desired ratio. In the diaper pad of the present invention, the amount of the pad core disposed in the back body is preferably 2 to 5 times (weight ratio) the amount of the pad core disposed in the front body. Only in the case of the comparison of the amount of pad cores in this case, as shown in FIG. 3, the upper edge 1a of the front body and the upper edge 1b of the rear body of the diaper pad of the present invention are overlapped. And the amount of the pad core used on the rear side of the folding line 41 is preferably 2 to 5 times (weight ratio) the amount of the pad core used on the front side of the folding line 41. .

  Since the amount of the pad core disposed on the rear side is larger as described above than the amount of the pad core disposed on the front side, even when urinating while sleeping, urine is sufficiently absorbed even on the buttocks side. It is possible to reduce the wearer's discomfort such as a wet feeling and a sticky feeling, and to further prevent the urine from leaking above the rear waist. Moreover, since the amount of pad cores arranged on the front side is smaller than those on the rear side, the feeling of pressure on the abdomen is less and the wearing feeling is further improved.

  Similarly, in the diaper pad according to the present embodiment, when the front side and the rear side are overlapped as shown in FIG. 3, the area of the appearance of the front body of the diaper pad (the front side of the folding line 41). The area is designed to be smaller than the area of the appearance of the back body (the area behind the folding line 41).

  In hospitals and elderly care facilities, a large amount of diapers are washed and dried with a dryer. Usually, diaper pads are provided with rubber tape on the edges of the left and right sides of the crotch so that the front body and back body are warped on the skin side, or gathers 40 etc. as appropriate. In this case, the front body and the back body are bent toward the skin centering on the crotch part, and the front body and the back body often overlap. At this time, if the area of the front body and the back body is almost equal, it will be difficult to dry the overlapping part of the front body and back body, it will take time to dry, large quantities of diapers such as hospitals and elderly care facilities Time and cost are considerably increased when they must be washed and dried. However, the area of the front body of the diaper is smaller than the area of the back body, so the area of the front body and the back body is different. This is preferable because it can save considerable time and cost. Moreover, since the front body is small, even when it overlaps with the back body, the front body easily moves when rotating in the dryer, and the overlapping position often changes, so that drying becomes easy.

  In this case, it is preferable that the area of the appearance of the front body of the diaper pad is 70 to 50% of the area of the appearance of the back body. If the area of the front body is too small, urine is likely to leak from the front side during urination, so the area of the appearance of the front body of the diaper pad is in the range of 70 to 50% of the area of the appearance of the back body. By doing so, while preventing the urine from leaking easily from the front side during urination, the area of the front body and the back body is different as described above. This is preferred because it can save significant costs.

  In the diaper pad according to the present invention, the area and amount of the pad core disposed on the rear side are larger than the area and amount of the pad core disposed on the front side. Is sufficiently absorbed even on the buttock side, reducing the wearer's discomfort such as a wet feeling and stickiness, and further preventing urine from leaking in the rear waist direction. In addition, since the area and amount of the pad core disposed on the front side are smaller than those on the rear side, the feeling of pressure on the abdomen is reduced and the wearing feeling is improved.

  Moreover, the upper part of the upper and lower left and right bulge parts of the human body buttock and the upper part between the left and right bulge parts of the buttock are used as a pad core whose thickness is thicker than the thickness of the pad core at the part where the left and right bulge parts of the buttock abut. Therefore, it distributes the concentration of pressure on the swollen buttocks of the human body, which is subject to pressure in the bed, to reduce or prevent pressure ulcers from occurring in areas where pressure ulcers tend to occur, and to mitigate the deterioration. It is possible to provide a diaper pad having a good wearing feeling that also has the above. Therefore, it is useful as a diaper pad for adults requiring care who have been laid down in bed.
