Description

Undergarment

This disclosure relates to an undergarment suitable for supporting pelvic floor muscles and preventing urinary incontinence due to loosening of the pelvic floor muscles.

Panties and girdles that also serve as supporters for preventing various symptoms caused by loosening and displacement of the pelvis are conventionally known.

For example, a female pelvis supporter described in Japanese Utility Model Publication No. 58-46313 (Patent Document 1) has a highly elastic belt attached to a female panty made of a stretchable cloth. The belt is attached so as to compress both the iliac crest, the pubic joint, and the lower part of the sacrum. A cloth with poor elasticity is attached to the front of the panties for the purpose of applying moderate pressure to the lower abdomen.

The body shape correction garment described in Japanese Patent No. 4789684 (Patent Document 2) can be used as a girdle, tights, etc. for the purpose of preventing pelvic displacement and posture correction, and a V zone is formed in the front body. The main belt-shaped part is arranged so as to surround the periphery of the pelvis corresponding part from the left and right sides of the V zone to the center part of the back body, and a strong tightening force can be applied in the left and right direction from the V zone. An auxiliary belt-like portion having a strong tightening force in the left-right direction is disposed below the main belt-like portion in the lower abdominal portion corresponding to the V zone. The auxiliary belt-shaped portion can generate a component force that pulls the V zone upward.

Japanese Utility Model Publication No. 58-46313 (JP 1983-46313 U) Japanese Patent No. 4789684 (JP 47789684 B2)

Conventional panties and body shape correction garments have an action of lifting the pelvis from the bottom to the top, but also have an action of pressing the abdomen together with the action. However, stress urinary incontinence often experienced by women after childbirth and middle-aged women seems to tend to increase in frequency by compressing the abdomen.

In the present invention, it is an object to provide an undergarment for women improved so that stress urinary incontinence can be reduced or prevented.

The present invention according to the disclosure includes a front body and a rear body having a lateral direction and a longitudinal direction perpendicular thereto, and elastically extending front and back bodies, and a crotch portion having a front end portion and a rear end portion, The front end and the rear end are in an improvement of an undergarment joined to the front body and the back body.

The present invention further includes the following configuration. At the time of wearing, the front body can cover the abdomen of the wearer of the undergarment, and the back body is formed so as to cover the wearer's buttocks, groin and side, The crotch part is formed so as to be able to cover the wearer's crotch part, and does not extend in the longitudinal direction at the central part in the lateral direction, and a first crotch part located on the front side of the undergarment; Clothing pressure generated by the undergarment when elastically stretched in the vertical direction and positioned on the back side of the undergarment and overlaid on the first crotch portion and worn by a human body dummy of an adult female Except for the clothing pressure in the waistline of the undergarment, in the crotch part, the part covering the groin and the part covering the side part. Higher than the clothing pressure at a portion where the garment pressure covering the abdomen.

The term “undergarment” refers to women's undergarments including panties, girdles, women's pants, women's undershorts, and the present invention refers to other women's undergarments, such as women's briefs, women's tights, women's pelvis. It should be understood that it is also applicable to supporters.
The term “joint” refers to stitching, seaming by adhesive or welding, preferably suturing.

When the undergarment according to one or more embodiments of the present invention is worn, the clothing pressure in the crotch part, the part covering the groin and the part covering the side part is higher than the clothing pressure in the part covering the abdomen. The pelvic floor muscles can be easily contracted by supporting the pelvis from below by the crotch part and the part covering the groin and simultaneously supporting the pelvis from the side part covering the side part. In addition, the deformation of the abdomen due to the abdominal pressure can be released toward the outside of the front body. In such an undergarment, the pelvic floor muscles are not pushed down by abdominal pressure, and even loose pelvic floor muscles can act to tighten the bladder and urethra. Therefore, according to the undergarment according to one or more embodiments of the present invention, stress urinary incontinence can be reduced or prevented.

The following embodiments relate to the undergarment shown in FIGS. 1-3, and include selective and preferred configurations as well as the essential configurations of the invention.
An example of the undergarment according to the present invention will be described with reference to the accompanying drawings as follows.

In FIG. 1A, the undergarment 1 includes a front body 2, a back body 3, and a crotch portion 4, and a waist opening 1 a is defined by the front body 2 and the back body 3. A pair of leg openings 1 b are defined by the back body 3 and the crotch portion 4. The undergarment 1 also has a longitudinal direction A and a transverse direction B perpendicular to each other, and is made symmetrical with respect to a line CC that bisects the dimension of the transverse direction B.

The front body 2 and the back body 3 include the first elastic fabric according to the present invention that elastically stretches in two directions, the longitudinal direction A and the lateral direction B, for example, a bear tengu known as a two-way stretch fabric. In the illustrated example, the fabric width of the front body 2 is slightly narrower than the fabric width of the back body 3, and the seam line 6 between the front body 2 and the back body 3 is visible in FIG. In the undergarment 1, a portion along the seam line 6 is a portion 7 that covers a wearer's side (not shown).

The crotch part 4 includes a first crotch part 4a located on the front side of the undergarment 1, and a second crotch part 4b described later, which is located on the back side of the undergarment 1 and overlaps the first crotch part 4a. The first crotch portion 4a shown in FIG. 4 is substantially non-extensible so that at least the central portion 11 in the horizontal direction B does not extend or hardly extends in the vertical direction A and the horizontal direction B. For example, satin (trade name, hereinafter the same) known as non-stretch fabric. An elastic fabric that is the same as that of the front body 2 is used for both side portions 12 of the first crotch portion 4a. This elastic fabric is for softening the touch of the first crotch portion 4a, and the undergarment 1 can also be made by omitting it. In the first crotch portion 4a, the seam line 13 with the front body 2 and the seam lines 16 with the center portion 11 and the both side portions 12 can be seen. Regarding the crotch part 4 and the first crotch part 4a, the lateral direction B can be called the width direction.

In FIG. 1 (b), the back body 3 has an inelastic fabric extending in the longitudinal direction A against the cracked portion 17 that covers the crack (not shown) of the undergarment wearer. The seam is sewn by a line 14, a pair of seam lines 18, and a seam line 19 extending between the pair of

seam lines

18 and 18. The seam line 14 is connected to the back body 3 and the first crotch part 4a, and the pair of seam lines 18 and the horizontally extending seam line 19 are arranged behind the inelastic fabric of the cracked part 17. The body 3 is joined, for example, stitched. The seam line 18 extends to the waist line 21 of the undergarment 1. The inelastic patch fabric of the rupture portion 17 is co-fabricated with the central portion 11 of the first crotch portion 4a. Back body 3 After this occurs, a pair of seam lines 18, and the left buttock 3 _L covering the left hip of the wearer, and is divided into a right hip 3 _R covering the right buttock. In the present invention, left and right mean left and right for the wearer.

FIG. 2 is a diagram showing the back side of the undergarment 1 by turning over the undergarment 1 of FIG. 1, (a) mainly showing the back side of the front body 2, and (b) mainly showing the back side of the back body 3. ing.

In FIG. 2 (a), the back body 3 can use CSY Tendon (trade name, the same below) as a two-way stretch fabric in addition to Bear Tengu (trade name, the same below). In FIG. 2A, the first elastic fabric in the front body 2 is used as a first patch (patch) 31 of the undergarment 1 in the portion 7 a belonging to the front body 2 among the portions 7 covering the side portions. A fabric having a higher elongation force, for example, one power net (trade name) is joined to the front body 2 at the seam wire 6 and the

seam wires

32, 33, 34, for example, stitched. The seam line 32 is formed with respect to the fabric of the front body 2 forming the waist line 21 and the fabric of the folded portion thereof, and the fabric of the back body 3 and the fabric of the folded portion thereof. This is a “stitch” applied to the peripheral edge of 1b. The seam line 34 is for joining, for example, suturing the first patch 31 to the front body 2. In the portion 7b belonging to the back body 3 among the portions 7 covering the side portions, a second covering cloth (patch) 36 in the undergarment 1 is made of a cloth having a higher extension force than the elastic cloth in the back body 3, for example, two layers. A so-called power net (trade name, the same applies hereinafter) is joined, for example, stitched, to the back body 3 at the seam wire 6 and the

seam wires

32 and 33.

The same cloth of the front body 2 is used for the lining 37 of the first crotch part 4a. On the back side of the first crotch portion 4a, a second crotch portion 4b extending downward from the seam line 13 is formed. The second crotch portion 4b is formed by the first, second, and

third sheets

51, 52, and 53 that overlap each other, as is apparent from the broken portion. The first sheet 51 is a waterproof sheet in the second crotch portion 4b, is formed of a water-impermeable sheet, is located at a position facing the wearer's skin, and is used with the undergarment 1 (not shown). Z) can be superimposed. The 2nd sheet | seat 52 is for supporting a wearer's pelvic floor muscle (not shown) from the downward direction, The 2nd elastic fabric in this invention which can be elastically extended in the vertical direction of the undergarment 1, For example, A power net is used. The third sheet 53 is for fixing an adhesive wing portion (not shown) in the incontinence pad so as to be peelable, and for example, a so-called marquisette (trade name, the same applies hereinafter) is used. However, if the undergarment 1 does not need to take into account the use of incontinence pads, in other words, if the undergarment 1 is intended solely for pelvic floor muscle or pelvic support, The first sheet 51 and the third sheet 53 can be omitted from the 2 crotch portion 4b. 2A, the front end portion 41a is joined to the undergarment 1 in the entire lateral direction B together with the first crotch portion 4a, for example, is sewn, but both side edges extending in the longitudinal direction A 41c is separated from the back surface of the first crotch portion 4a.

In (b) of FIG. 2, in each of the left buttock 3 _L and the right buttock 3 _R of the back body 3, as patch cloth for the portion extending in the transverse direction B along the waist line 21, of an elastic fabric in the back body 3 A fabric having a high elongation force, for example, one power net 61 is joined, for example, stitched, at the

seam lines

6, 18, 32, 62. The seam line 62 is between the seam line 6 (see FIG. 2A) and the seam line 18 and forms an arc. Moreover, the heel groove part 35 equivalent to a wearer's heel groove from the rear end part 40b of the 1st crotch part 4a to the lower end part 63 of the part 7b which covers a side part, and the lower end part of the part 7b which covers a side part A portion 7b covering the side part from 63 to the waistline 21 has a higher stretching force than the first elastic fabric in the back body 3 as a patch (patch), for example, a double-layered power net 64 is a seam line 6 (see FIG. 2 (a)), 18, 33, 66 are joined to the undergarment 1, for example, stitched. The seam line 66 is between the seam line 18 and the seam line 32 and extends in an arc. In the back body 3, the upper end 68 of the bridge 67 extending in the longitudinal direction A along the center line CC is joined, for example, sewn to the back body 3 at the seam line 32. A lower end portion 69 of the bridge 67 is stitched to the rear end portion 41b of the second crotch portion 4b. The bridge 67 is formed of a cloth, for example, a power net, that is elastically stretchable in at least the vertical direction A of the vertical direction A and the horizontal direction B. Overhangs (not shown) are applied to both side edges of the power net. In the illustrated example, the bridge 67 is shown in a state in which the middle portion in the longitudinal direction A is broken.

In FIG. 2 (b), the rear end portion 41b of the second crotch portion 4b is also arced so as to substantially overlap the seam line 14, and at both side portions 71 in the lateral direction B with respect to the first crotch portion 42a. While being joined, for example, stitched, the

side portions

71 and 71 are separated from each other without being joined, for example, stitched, to the back body 3 or the first crotch portion 4a. Therefore, when the bridge 67 is pulled upward in the longitudinal direction A in the worn undergarment 1, the rear end portion 41b of the second crotch portion 4b is upward so that at least the center in the lateral direction B follows the bridge 67. The second crotch portion 4b is pulled and can elastically extend while closely contacting the wearer's skin at the pubic bone and anus, and can act to push up the wearer's pelvic floor muscles. The second crotch portion 4b acting in this way is sewn to the undergarment 1 at the position corresponding to the pubic bone or below the front end portion 41a so as not to press the wearer's abdomen. preferable. There is no special rule about the position where the rear end portion 41b of the second crotch portion 4b is sewn to the undergarment 1.

In the worn undergarment 1, the inelastic fabric used for the central portion 11 of the first crotch portion 4 a shown in FIGS. 1A and 1B and the cracked portion of the back body 3 are also used. The second crotch portion 4b is also acted by acting so that the non-elastic material used in 17 is bitten into the crack and pushes up the second crotch portion 4b from the front side to the back side of the undergarment 1. The degree of pressure contact with the skin increases, and the action of pushing up the pelvic floor muscles is strengthened.

In the worn undergarment 1, the pelvis is also in a state where a double-layered power net 64 having a high extension force joined, for example, stitched to the portion 35 covering the groin, is elastically extended along the groin. Can be supported from below the buttocks. Further, the two-layered power net 64 having a high extension force joined to, for example, stitched to the side portion 7b can support the pelvis from the side and suppress the movement of spreading to the side of the pelvis. . This support of the pelvis makes it easier for the pelvic floor muscles to contract. Furthermore, the center part 2a (see FIG. 1 (a)), which is the part of the front body 2 that covers the wearer's abdomen, more specifically, is located above the part corresponding to the pubic bone when worn. The center portion 2a between the portions corresponding to the left and right iliac bones is formed of only the first elastic fabric that elastically stretches in two directions. The abdominal pressure allows it to escape from the central portion 2a toward the outside of the undergarment 1, preventing the abdominal pressure from acting to push down the pelvic floor muscles. The ability to support the pelvis in this way and to relieve abdominal pressure in this way can support the bladder and urethra even when the pelvic floor muscles are loose. Because it tightens, it is possible to prevent urinary incontinence even when the wearer coughs or has heavy baggage and is under abdominal pressure.

In other words, this undergarment 1 was caused by pregnancy, childbirth, obesity, etc., and the pelvic floor muscles loosened and the bladder and urethra fell, coughing, and holding heavy loads caused abdominal pressure. Sometimes, the urethra cannot be tightened well, and in the case where urine tends to leak, a particularly excellent effect can be exhibited.

In an example of the fabric used for the undergarment 1, the bare tengu (trade name, hereinafter the same) includes 89% by mass cotton yarn and 11% by mass urethane yarn, and the mass per m ² is 150-160 g. Things can be used. CSY sheeting (trade name, hereinafter the same), the use a rayon yarn of 56 wt%, and 35 wt% of cotton, and a 9 wt% of the urethane yarn, those mass per 1 m ² of 165-175g can do. As the satin, those formed of 100% by mass of polyester yarn and having a mass per m ² of 155 to 165 g can be used. As the power net, 82 mass% nylon yarn and 18 mass% urethane yarn, and a mass of 145 to 155 g per m ² can be used. The first sheet 51 in the second crotch portion 4b may be formed of 100% by mass polyester yarn and have a mass of 105 to 115g per m ² . For the third sheet 53, a marquette formed of 100% by mass polyester yarn and having a mass per 1 m ² of 55 to 65 g can be used.

Table 1 shows the easiness of elongation of these fabrics measured for the bear sheet, power net, marquisette, and first sheet. In this measurement, five test pieces having a width of 30 mm and a length of 140 mm were prepared for each fabric. The length direction of the test piece was made to coincide with the longitudinal direction of the undergarment 1 in which the fabric was used (however, with respect to the crotch portion 41, the longitudinal direction of the undergarment 1). For each test piece, use a tensile tester to enter a pair of marked lines so that the distance between marked lines is 100 mm with an initial load of 29 mN applied, and then add the following load. The elongation (mm) and elongation (%) of the distance between the marked lines after 1 minute were measured.
(1) Distance between marked lines: 100 mm
(2) Load: 8.82N
(3) Number of measurements: 5 times

According to Table 1, it is considered that the stretching force required to stretch each fabric by a certain amount increases in the following order: Bear Tengu, Power Net, Waterproof Cloth, and Marquisette.

When the undergarment 1 made using these fabrics is worn, each part of the undergarment 1 acts to closely support the pelvis and pelvic floor muscles and to press the abdomen. In order to know the degree to which it is worn, in the present invention, the clothing pressure was measured using a body dummy 100 (see FIG. 4 below) of an adult girl. The dummy 100 was produced by Shibuya et al. With reference to human body size data of women in their 40s in the “Japanese Human Body Data Book (2004-2006)” by the Human Life Engineering Research Center (HQL), Tokyo. The walking movement dummy owned by Tokyo Metropolitan Industrial Technology Research Center Sumida Branch (Tokyo Metropolitan Industrial Technology Research Center Research Report No. 7, P.58-61, 2012) was adopted. In the dummy 100, an air pack AM13037-10 manufactured by AIM Techno was incorporated as a pressure measuring instrument. In addition, the dummy 100 is made to wear an M-size test undergarment, a commercially available M-size undergarment for incontinence patients, and a commercially available M-size fabric undergarment in order, The clothing pressure by each undergarment was measured. For the undergarment for the test, the size of the M-size hip in the basic body dimensions described in Table 11-3 of JIS L 4005 (2001 version) “Size of clothing for adult girls” was applied. The size of the M size hip in the table is 87-95 cm. In addition, about the undergarment for a test, the ease of elongation of each site | part was measured prior to the measurement of clothing pressure.

Table 2 shows the measurement results of the easiness of elongation of each part in the test undergarment. In this measurement, a total of five test pieces each having a width of 10 mm and a length of 50 mm were sampled from each of the five undergarments. The length direction of the test piece was made to coincide with the length direction of each part, and the width was a direction orthogonal to the length direction. For each test piece, using a tensile tester, write a pair of marked lines so that the distance between the marked lines is 30 mm with an initial load of 29 mN, and then add the following load. The elongation (mm) and elongation (%) of the distance between the marked lines after 1 minute were measured.
(1) Distance between marked lines: 30 mm
(2) Specimen width: 10 mm
(3) Load: 2.94N
(4) Number of measurements: 5 times

3 and 4 are diagrams showing a pie chart showing the measurement result of the clothing pressure and the clothing pressure measurement position in the dummy 100. FIG. For the test undergarment having the characteristics shown in Table 2, the clothing pressure is the portion immediately above the urethra mouth of the dummy 100 (shown as urethra mouth in FIG. 3) facing the crotch portion 41 shown in FIGS. , The part immediately above the anus (indicated as anus in FIG. 3), the anal part of the groin of the dummy 100 facing the part 35 covering the groin shown in FIGS. 2, the portion below the iliac crest of the side portions of the dummy 100 facing the side portion 7 b that covers the side portions shown in FIG. 2 (shown as side in FIG. 3), the abdomen shown in FIG. 2. The measurement was performed on each of the belly portions of the dummy 100 facing the central portion 2a of the abdomen, which is a portion covering the surface. In addition, in the dummy 100, the clothing pressure at the portion facing the waistline 21 was excluded from the object to be compared with the clothing pressure, and was not measured. For other undergarments, the clothing pressure was measured at the same position as the test undergarment.

The dummy 100 was attached with a 2 type and 5 type pressure sensor made by AIM Techno and connected to the air pack AM13037-10 made by the same company. The type 2 pressure sensor had a diameter of 20 mm, and was used for measuring the clothing pressure in a portion other than the portion facing the crotch portion 41. The type 5 pressure sensor had a width of 8 mm and a length of 28 mm, and was used to measure the clothing pressure at the portion facing the crotch portion 41. In FIG. 3, a commercially available urine absorbing pad for incontinence patients (“Characterized Absorption Sarah” (registered trademark) for small amount (15 cc) manufactured by Unicharm Corporation) is attached to the crotch portion 41 of the test undergarment. The clothing pressure for the case is also shown.

4 (a) and 4 (b) show the measurement positions of the clothing pressure on the ventral side and the back side in the dummy 100 on which the undergarment 1 is worn. In (a) and (b), the dummy 100 is in an inverted state. The pressure sensor used to measure the clothing pressure is covered with the undergarment 1 and cannot be seen. The undergarment 1 is the same as that illustrated in FIGS. 1 and 2 except that a decorative lace fabric LC is sewn to the periphery of a leg opening (not shown).

In FIG. 3, when comparing the clothing pressure between the test undergarment and other undergarments, the test undergarment can be said as follows. Between the urethral opening and the anus, the crotch part 41 closely adhered to the skin of the wearer's crotch part, and the clothing pressure was particularly high in the vicinity of the urethral opening. The portion 35 covering the groin was in close contact with the skin in a wide range extending from the anal portion to the side portion, and no significant change was observed in the distribution of clothing pressure. The test undergarment also did not adhere strongly to the abdomen. Further, when comparing the clothing pressures for the test undergarments, the clothing pressure in the crotch portion 41, the portion 35 covering the groin, and the portion 7b covering the side portions is the clothing pressure in the central portion 2a which is the portion covering the abdomen. Higher than the pressure. In addition, the clothing pressure of the crotch portion 41 represented by the clothing pressure at the urethral opening was higher than the clothing pressure at the portion 35 covering the groin and the portion 7b covering the side portions. Furthermore, the clothing pressure decreases in the order of clothing pressure in the crotch portion 41, clothing pressure in the portion 35 covering the groin, clothing pressure in the portion 7b covering the side, and clothing pressure in the central portion 2a that covers the abdomen. It was.

According to the test undergarment in which the clothing pressure is distributed in this way, the pelvic floor muscles can be supported by the crotch portion 41, and at the same time, the pelvis is supported from the periphery of the buttocks and the pressure from the outside of the side to the pelvis. Since the pelvis can be tightened by adding, it becomes easy to contract even the pelvic floor muscles that are loosened. Moreover, in this test undergarment, since the abdomen is not compressed, it is easy to release the abdominal pressure generated when the wearer holds a heavy object toward the front of the abdomen. FIG. 3 also shows that this effect on the test undergarment is more pronounced when used with a urine absorbing pad.

In FIG. 3, among the clothing pressures in the crotch portion 41, the high clothing pressure in the vicinity of the urethral opening and the vicinity of the anus means that the front end portion of the crotch portion 41 is separated by the front body 2 and the back body 3. It is considered that this means that the crotch portion 41 is firmly attached to the crotch portion of the dummy 100 by strongly pulling up the rear end portion. Further, the fact that the clothing pressure is detected in the vagina is considered to prove that the crotch portion 41 is in close contact. However, in the vagina, the crotch portion 41 is tightly adhered, so that the dummy formed of a flexible material is deformed, and as a result, the clothing pressure is lower than the clothing pressure of other portions. It is done. Therefore, in the present invention, the clothing pressure in the vagina is excluded from the comparison of clothing pressure between the undergarments.
