Description

Clothing with crotch part

This invention relates to the clothing which has the crotch part which coat | covers a local part.

Urinary accumulation and urination are controlled by contraction and relaxation of the urethral sphincter in the pelvic floor muscles. Moreover, when the pelvic floor muscles loosen due to aging or the like, urine accumulation and urination may not be well controlled, and urinary incontinence may occur.

Therefore, shorts that improve relaxation of the pelvic floor muscle group and can cope with urinary incontinence are known (see, for example, Patent Document 1). In the shorts described in Patent Document 1, the absorbent pad provided in the local area is lifted upward from the front surface and the back surface. As a result, the absorbent pad compresses the crotch portion, and the pelvic floor muscle group is supported and pulled. Therefore, the shorts described in Patent Document 1 are expected to alleviate urinary incontinence disorders.

(Embodiment)
According to the knowledge of the inventors, when the pelvic floor muscle group P102 in the left diagram of FIG. 9 is relaxed, the height position of the pelvic floor muscle group is lowered like the pelvic floor muscle group P102 ′ in the right diagram of FIG. Along with this, the position of the bladder P101 supported by the pelvic floor muscle group P102 also falls as shown by the bladder P101 ′ in the right diagram of FIG. 9, and at this time, the bladder neck lowers to the height position L102. Thus, when the pelvic floor muscle group relaxes, the distance between the bladder neck and the outside cannot be secured, the bladder neck becomes difficult to tighten, and urinary incontinence is likely to occur. It can be seen that the bladder neck height position L102 in the right state of FIG. 9 in which urinary incontinence is likely to occur is lower than the normal position L101 of the bladder neck in the left figure. The pelvic floor muscle groups P102 and P102 ′ are generic names of muscles constituting the pelvic floor.

Therefore, the shorts 1 according to the embodiment of the present invention supports the female local part, and returns the bladder P101 'and the pelvic floor muscle group P102' to the normal positions as shown in the left diagram of FIG. Thereby, the shorts 1 can secure the distance between the bladder neck and the outside, and can easily tighten the bladder neck. Such shorts 1 makes it possible to maintain a state in which urinary incontinence is difficult to occur.

The inventors efficiently raise the pelvic floor muscle group P102 and relieve urinary incontinence by pressing the perineum tendon center P111, the shallow perineum lateral muscle P112, the levator ani muscle P113, etc. shown in FIG. I found that it was effective. The perineum tendon center P111 is located on the center line between the urethra P121 and the vagina P122 and the anus P123. The shallow perineum lateral muscle P112 is located in the left-right direction from the perineum tendon center P111. The levator ani muscle P113 is located around the anus P123.

The shorts 1 according to the embodiment of the present invention concentrates the perineum tendon center P111, the shallow perineum lateral muscle P112, the levator ani muscle P113, and the like without randomly pressing the entire local area or the entire pelvic floor muscle group P102. It is possible to relieve urinary incontinence effectively with a comfortable wearing comfort.

As shown in FIGS. 1 to 3, a shorts 1 according to an embodiment of the present invention includes a crotch portion 10 provided in a local portion and a main body portion. The main body includes a front body part 50 and a back body part 60. The front body part 50 and the back body part 60 are respectively connected on the left and right sides of the wearer. The crotch part 10 and the front body part 50 are connected via the front connecting part 16, and the crotch part 10 and the rear body part 60 are connected via the rear connecting part 17.

(Crotch part)
The crotch part 10 includes an outer crotch part 11, a crotch tightening part 15 provided on the skin side with respect to the outer crotch part 11, and a skin side crotch part 14 provided on the skin side with respect to the crotch tightening part 15. The crotch part 10 is formed by overlapping the outer crotch part 11, the crotch tightening part 15, and the skin side crotch part 14 in this order from the outside toward the skin side.

The outer crotch part 11 includes a crotch center part 12 provided at a position corresponding to the left and right center line of the local area, and a crotch left and right part 13 provided at a position corresponding to the outside (side side) of the local left and right center line.

The outer crotch part 11 has elasticity. The outer crotch portion 11 presses the perineum tendon center P111 with the tightening force of the crotch center portion 12, and presses the shallow perineum lateral muscle P112 with the tightening force of the crotch left and right portions 13.

The crotch center portion 12 is formed to have a higher tightening force than the crotch left and right portions 13. The crotch center portion 12 corresponds to a connection portion between the left fabric and the right fabric forming the crotch left and right portions 13. By providing an easily stretchable tape member such as a rubber string on the back side (skin side) of the crotch center portion 12, a gathered collection of the left side fabric and the right side fabric forming the crotch left and right portions 13 is formed. . The crotch center part 12 can be expanded and contracted so as to fit the shape on the left and right center line of the local part due to the elasticity of the tape member, and can press the left and right center line of the local part. In the embodiment of the present invention, the case where the tape member provided in the crotch center portion 12 is formed integrally with the rear tightening portion 20 described later will be described, but is not limited thereto.

Here, the shape of the local part in the frontal plane cross section of the wearer (cross section obtained by tying the wearer's left and right and cutting back and forth) will be described. The local left and right center lines in the frontal plane cross section are located deeper than the periphery, located above the periphery, and the side sides (outside) of the peripheral left and right center lines are below the left and right center lines Located in. In the frontal plane cross section, the local portion is formed in an inverted V shape with the left-right center line as a vertex. Since the perineum tendon center P111 is located on the left and right center line, and the shallow perineum lateral muscle P112 is located on the side of the left and right center line, the perineum tendon center P111 is located above (back side) the shallow perineum lateral muscle. Will do.

The shorts 1 according to the embodiment of the present invention is formed so as to easily conform to the shape of the wearer's local area as described above. Specifically, the crotch center portion 12 has a higher tightening force than the crotch left and right portions 13, so that the crotch center portion 12 enters the back, and the perineum tendon is located at the apex of the inverted V shape on the left and right center lines. It becomes possible for the crotch center part 12 to press the center P111. Furthermore, since the gathers are provided in the crotch central portion 12 and the crotch left and right portions 13 are also stretchable, the crotch left and right portions 13 are pressed along the shallow perineum lateral muscle P112 located in the inverted V-shaped inclined portion. . Thereby, the crotch part 10 can press the perineum tendon center P111 and the shallow perineum lateral muscle P112 along the shape of the local part.

The front end of the crotch center portion 12 is provided at a position corresponding to the perineum tendon center P111. As shown in FIG. 1, the front connecting portion 16 connects the outer crotch portion 11 and the crotch tightening portion 15 of the crotch portion 10 to the front body portion 50. The front connecting portion 16 is formed in a V shape in which the front end of the crotch center portion 12 is a valley. Since the perineum tendon center P111 is the tip of the crotch center part 12 and corresponds to the V-shaped valley, the shorts 1 are worn and the crotch center part 12 extends rearward. It is possible to collect power and tighten it.

Also, the crotch left and right part 13 is provided to extend further forward than the crotch center part 12 and is provided so as to press the front left and right from the perineum tendon center P111. The crotch left and right portions 13 are positioned not only on the side of the perineum tendon center P111 but also on the left and right front and left and right sides of the perineum tendon center P111, so that the crotch left and right parts 13 are positioned in the left and right direction (side direction) from the perineum tendon center P111. It becomes possible to tighten the shallow perineum lateral muscle P112 on a wide surface.

The rear connection part 17 connects the outer crotch part 11 of the crotch part 10 and the rear body part 60. Further, on the left and right center line of the rear connecting portion 17, the rear connecting portion 17 is connected to the rear end of the crotch portion 10 of the crotch portion 10. As shown in FIG. 2, the rear connecting portion 17 is arranged to draw an arc so that the vicinity of the left and right center line is high and low on the side. The crotch center portion 12 is disposed so as to be connected to a rear center portion 30 described later. The tape member provided in the crotch center part 12 may be provided by extending to the skin side of the back body part 60.

The crotch tightening portion 15 is provided closer to the skin than the outer crotch portion 11 and has a tightening force. The crotch tightening portion 15 expands and contracts following the inverted V shape formed by the outer crotch portion 11 (the crotch center portion 12 and the crotch left and right portion 13), and tightens the perineum tendon center P111 and the shallow perineum lateral muscle P112. Press.

The skin side crotch part 14 is provided on the skin side with respect to the crotch tightening part 15, and is formed of a highly extensible member. Since the skin-side crotch part 14 is formed of an easily stretchable member, the skin-side crotch part 14 conforms to the inverted V shape formed by the outer crotch part 11 and does not hinder local tightening by the crotch tightening part 15. Moreover, a feeling of wear can be improved by forming the skin side crotch part 14 with a smooth member.

(Back body part)
As shown in FIGS. 2 to 4, the rear body part 60 includes a rear center part 30 and a rear tightening part 20.

The rear center part 30 is a position corresponding to the left and right center lines of the back side (rear body part 60) of the main body part, and the waist on the back side (rear body part 60) of the main body part from the rear end of the crotch center part 12. Is provided at the height position. The rear center portion 30 has a tightening force higher than that of the main body portion near the waist height position, and has a tightening force higher than that of the waist portion near the rear end of the crotch center portion 12. The vicinity of the rear end of the crotch center portion 12 of the rear center portion 30 is formed so as to expand and contract integrally with the crotch center portion.

The rear center portion 30 is formed by extending a tape member disposed in the crotch center portion 12 on the left and right connection portions of the back body. This tape member is formed so as to exhibit a high tightening force and is less likely to extend than the rear body portion 60 by being fixed while being stretched on the upper side (waist side) of the rear center portion 30. With this tightening force, the tape member can pull up the crotch portion 10 (particularly the crotch center portion 12) from the waist side and press a predetermined position of the local portion. Further, the tape member is formed so as to be easily extended together with the crotch portion 10 by being fixed in a state where the room for extension is left below the crotch portion 10 (on the crotch side) and the crotch portion 10. Thereby, the part near the local part of the rear center part 30 can be extended and contracted so as to follow the shape on the left and right center line of the local part and the shape of the collar part.

Thus, the tape member provided in the rear center portion 30 and the crotch center portion 12 expands and contracts along the shape of the local portion in the vicinity of the crotch center portion 12 and is pulled up by the tightening force above the waist. Thereby, the back center part 30 can support that the crotch center part 12 adheres to the perineum tendon center P111, and applies power appropriately. Since the crotch central portion 12 can be in close contact with the perineum tendon center P111 and can be appropriately powered, the posterior central portion 30 is further suitable for the crotch left and right portions 13 to the shallow perineum lateral muscle P112 on the side of the left and right centerline. Can assist in applying power.

The rear tightening portion 20 has a tightening force higher than that of the main body portion (rear body portion 60), and tightens the left and right levator ani muscles P113.

The rear tightening portion 20 is formed so as to exert power to press the left and right levator ani muscles P113 by overlapping and partially connecting the fabric that exhibits the tightening force to the back body portion 60. The levator ani muscle P113 is known to be a relatively large muscle in the pelvic floor muscle group P102. When the rear tightening portion 20 presses the levator ani muscle P113, the pelvic floor muscle group P102 is efficiently used. It is possible to raise.

As shown in FIG. 4, the rear tightening portion 20 has a body portion (rear body portion 60) at a position P 22 corresponding to the side of the sciatic P 131 and a position P 23 corresponding to the local portion of the boundary between the lower limbs and the torso. Connect to the crotch unit 10. In the rear tightening portion 20, an opening 21 is provided between two positions P22 and P23 where the rear tightening portion 20 is connected to the main body portion. The opening 21 has a shape curved inward from the end of the main body, and is formed so as not to be connected to the main body.

The rear tightening part 20 is further connected to the main body part (rear body part 60) above the levator ani muscle P113 and connected to the rear central part 30 and the main body part in the vicinity of the left and right centers. The left and right sides (left and right ends) of the rear tightening portion 20 are not connected to the main body such as the rear body portion 60 and the opening 21 is not connected to the main body. In other words, the rear tightening portion 20 is formed in a floating structure in which the left and right sides (particularly the lower portion) of the rear tightening portion 20 and the opening 21 are not connected to the rear body portion 60 and the like. When the rear tightening portion 20 is connected to the back body portion 60 or the crotch portion 10 without being formed in such a floating structure, the rear tightening portion 20 follows the back body portion 60 or the crotch portion 10 while following the levator ani muscle Since P113 is tightened, tightening to the levator ani P113 is weakened. In connection with this, the perineum tendon center P111 pressed by the crotch center portion 12 is weakened, and the perineum tendon center P111 may not be appropriately pressed. On the other hand, in the shorts 1 according to the embodiment of the present invention, the rear tightening portion 20 is formed in a floating structure, so that the left and right sides of the rear tightening portion 20 and the opening 21 are the main body portion and the crotch. Arranged independently of the portion 10. As a result, the rear tightening section 20 tightens the levator ani muscle P113 without being affected by the movement of the main body section or the crotch section 10, and does not prevent the perineum tendon center P111 from being pressed by the crotch center section 12.

The rear tightening portion 20 may be connected to the main body portion in the vicinity of the waist height position. By connecting the rear tightening portion 20 to the main body portion in the vicinity of the height position of the waist, the rear tightening portion 20 is pulled upward from the stable position of the waist, and the rear tightening portion 20 is stretched to tighten the levator ani muscle P113. Can do.

Although the case where the rear tightening portion 20 is connected to the main body portion in the vicinity of the height position corresponding to the waist has been described, it is not limited thereto. For example, it is only necessary to connect the main body portion above and below the position corresponding to the levator ani muscle P113 so as to secure a size capable of tightening the levator ani muscle P113. The size of the rear tightening portion 20 and the position to be connected to the main body portion are arbitrarily set.

(Front body part)
As shown in FIGS. 1 and 4, the front body part 50 includes a front center part 40.

The front center part 40 is provided in the vicinity of the waist height position on the front side of the main body part (front body part 50) from the crotch part 10, and has a tightening force higher than that of the main body part. In the embodiment of the present invention, the front central portion 40 realizes a tightening force higher than that of the main body portion by further overlapping the fabric on the main body portion.

The front center part 40 supports local pressing by the crotch part 10 by pulling up the crotch part 10 from the front waist height position of the main body part.

The upper end of the front center part 40 is connected to the front body part 50, and is not connected to the front body part 50 in the vicinity of the lower abdomen of the front center part 40. As a result, the front center part 40 can be brought into close contact with the skin without following the front body part 50 and can raise the crotch part 10.

As shown in FIG. 4, the front center portion 40 has a wide surface covering the left and right center lines of the front lower abdomen, but is not limited to this, and the size of the front center portion 40 is not limited.

(Shorts hierarchy)
With reference to FIG. 5, the hierarchy of each part which comprises the shorts 1 which concerns on embodiment of this invention is demonstrated. The upper part of FIG. 5 corresponds to the skin side.

The skin side crotch part 14 and the front center part 40 are arrange | positioned in the part nearest to skin. The skin side crotch part 14 and the front center part 40 may be integrally formed with one member. The upper end (the left end in FIG. 5) of the front center part 40 is connected to the front body part 50. The skin side crotch portion 14 is connected to the rear tightening portion 20 and the outer crotch portion 11 in the vicinity of both sides of the local area (inside the boundary between the lower limbs and the torso). The rear end of the skin side crotch part 14 is connected to the rear center part 30, the rear tightening part 20 and the outer crotch part 11 on the left and right center line of the rear connecting part 17, and is not connected to the side of the left and right center line. Thereby, the skin side crotch part 14 makes it possible not to inhibit the tightening of the levator ani muscle P113 by the rear tightening part 20.

The crotch tightening portion 15, the rear tightening portion 20, and the rear center portion 30 are disposed outside the skin side crotch portion 14 and the front center portion 40. The crotch tightening portion 15 and the rear tightening portion 20 may be formed integrally with one member.

The front body part 50, the outer crotch part 11, and the rear body part 60 are disposed outside the crotch tightening part 15 and the rear tightening part 20. The front body part 50, the outer crotch part 11, and the rear body part 60 may be fixed to each other to form one sheet-like member.

The front ends of the crotch tightening portion 15 and the outer crotch portion 11 each have a V shape and are arranged so as to overlap. In the front connection part 16, the front ends of the crotch tightening part 15 and the outer crotch part 11 are connected to the lower end of the front body part 50. In the rear connection part 17, the rear end of the outer crotch part 11 and the lower end of the rear body part 60 are connected.

The rear center portion 30 is provided between the skin-side crotch portion 14 and the front center portion 40 that are integrally formed, and the crotch tightening portion 15 and the rear tightening portion 20 that are integrally formed. The rear center portion 30 is fixed to the crotch tightening portion 15, the rear tightening portion 20, the outer crotch portion 11, and the rear body portion 60 on the left and right center lines. The front end of the rear center portion 30 is provided at a position corresponding to the perineum tendon center P111 and corresponding to a V-shaped valley formed by the front ends of the crotch tightening portion 15 and the outer crotch portion 11.

Since the rear center part 30 is formed of a highly elastic tape member, the crotch center part 12 of the outer crotch part 11 expands and contracts so as to press the perineum tendon center P111. Further, the front end of the rear tightening portion 20 and the outer crotch portion 11 and the rear end of the front body portion 50 overlap the front connecting portion 16, and the front end of the rear center portion 30 is in a V-shaped valley formed by the front connecting portion 16. Overlap. Therefore, a large power can be applied to the V-shaped valley portion formed by the front connecting portion 16, specifically, the position corresponding to the perineum tendon center P111. Further, the rear center portion 30 pulls up the crotch center portion 12 from the waist height position. With such a configuration, the shorts 1 according to the embodiment of the present invention can improve the close contact of the crotch portion 10.

In addition, the hierarchy of each part shown in FIG. 5 is an example, Comprising: It does not restrict to this.

Here, a wearing test when 19 people wear the shorts 1 according to the embodiment of the present invention will be described. The subject (wearer) wearing the shorts 1 is a woman in whom relaxation of the pelvic floor muscle group P102 is observed. In the wearing test, MRI (Magnetic Resonance Imaging) is taken around the local area of the subject (wearer) wearing the shorts when not wearing the shorts 1 and when wearing the shorts 1 respectively. Furthermore, the height position of each bladder neck when not worn and when worn is specified from the non-weared and taken images when worn.

Referring to Table 1, the results of the wearing test will be explained. Table 1 shows the size of the shorts 1 worn by each subject and the elevation of the bladder neck for each of 19 subjects. The raising amount of the bladder neck is the height position of the bladder neck at the time of wearing, based on the height position of the bladder neck before wearing of each subject. In Table 1, when the height position of the bladder neck when worn is higher than the height position of the bladder neck when not worn, that is, when the bladder neck is raised, Takes a positive value.

As shown in Table 1, in all subjects, the raising amount of the bladder neck took a positive value, and the raising of the bladder neck when wearing the shorts 1 was confirmed. The average elevation of all subjects is about 8 mm. Since the typical urethra length of a woman is about 30-50 mm, it can be seen that wearing the shorts 1 can secure a length of about 15-30% of the normal urethra. That is, as described with reference to FIG. 9 and the like, when the pelvic floor muscles relax, it is difficult to tighten the bladder neck and urinary incontinence is likely to occur. By wearing the shorts 1 according to the embodiment of the present invention, It can be seen that the length of the urethra can be secured and the pelvic floor muscles can be supported. Thereby, it can be expected to effectively alleviate urinary incontinence.

Specifically, each test piece in the crotch central portion 12 and the crotch left and right portion 13 is inserted into two points 10 mm apart from each other in the crotch central portion 12 and the crotch left and right portion 13 of the shorts 1 sample. It is a chucked one. The stretch recovery property of the crotch center 12 is about 300 mm / min when a test piece in the crotch center 12 is attached to a constant speed extension type tensile tester and a load of 14.7 N is applied in the vertical direction (front and back direction of the wearer). Elongation recovery is repeated a plurality of times at a speed of, and is calculated by the average of the extension force (cN) when 40% is extended and the recovery force (cN) when 40% is recovered. The stretch recovery property of the crotch left and right part 13 is about 300 mm / min when a test piece in the crotch left and right part 13 is attached to a constant speed extension type tensile tester and a load of 14.7 N is applied in the vertical direction (front and back direction of the wearer). Elongation recovery is repeated a plurality of times at a speed of 5%, and is calculated by the average of the extension force (cN) when 30% is extended and the recovery force (cN) when 30% is recovered.

According to such shorts 1 according to the embodiment of the present invention, the crotch center portion 12 is formed so as to be highly stretchable, so that it contacts the perineum tendon center P111 located behind the both sides. It is possible to touch and press. Moreover, since the crotch center part 12 contacts the perineum tendon center P111, the crotch left and right parts 13 located on both the left and right sides of the crotch center part 12 can press the shallow perineum lateral muscle P112. The shorts 1 can contribute to the elevation of the pelvic floor muscle group P102 by simultaneously pressing the perineum tendon center P111 and the shallow perineum lateral muscle P112.

Furthermore, by providing the rear center portion 30 from the rear end of the crotch center portion 12 to the vicinity of the height position of the waist on the back side, the crotch center portion 12 is pulled up from the upper side on the back side, and the degree of adhesion at the perineum tendon center P111 is increased. Can be improved.

The rear tightening section 20 tightens the left and right levator ani muscles P113. Since the levator ani muscle P113 is a relatively large muscle in the pelvic tightening group, the rear tightening portion 20 can efficiently lift the pelvic floor muscle group P102.

In the rear tightening portion 20 according to the embodiment of the present invention, the opening 21 is provided, so that the levator ani muscle P113 can be pressed without hindering local pressing by the crotch portion 10.

The shorts 1 according to the embodiment of the present invention has the perineum tendon center P111, the shallow perineum lateral muscle P112, the anal peritoneal muscle P112, along the shape of the local area without randomly pressing the entire pelvic floor muscle group. Comfortable wearing comfort can be realized by intensively pressing the muscles P113 and the like.
