Description

  The present invention relates to a girdle that can train pelvic floor muscles by being attached to the body.

  As shown in FIG. 15, the pelvic floor muscle is a general term for muscles that close the urethra, anus, and vagina while supporting the abdominal organs (bladder, rectum, uterus, etc.), and is sometimes called a pelvic floor muscle group. When function declines due to aging or childbirth, urinary incontinence, fecal incontinence, and uterine prolapse may occur. Attempts to treat this are pelvic floor muscle exercises (training). However, pelvic floor muscle exercises are correct and will not be effective unless they are performed continuously for a long period of time. In addition, verbal explanation alone is not enough to learn pelvic floor muscle exercises, and it may be necessary for the instructor to recognize the position of the pelvic floor muscle group while conducting vaginal examination and to convey the correct contraction method, Implementation is also difficult in terms of invasiveness and psychological resistance.

  There are biofeedback therapy and intravaginal cones as a way to learn how to correctly contract the pelvic floor muscles and to continue exercise, but all of them require vaginal insertion of instruments, and are invasive and psychologically resistant. can not deny.

  The pelvic floor muscles (an levator ani, urethral sphincter, and anal sphincter) are muscles that can contract voluntarily, but not everyone can easily contract. About 30% of women with stress urinary incontinence are said to be unable to voluntarily contract the pelvic floor muscles.

  Existing pelvic floor muscles and surrounding muscular strength-strengthening exercise tools require vagina equipment insertion and are highly invasive (for example, Patent Documents 1 and 2). There are pelvic floor muscle strength strengtheners that do not require insertion of equipment into the vagina, but these are designed to be worn on the feet, sandwiched between the crotch, or sit on the device, and can be used freely while using Can't live a life (Patent Documents 3, 4, 5, 6). In addition, the muscle of the anus is pinched from the vicinity of the anus to the thigh, and the muscles of the anus are tightened so that they do not fall. However, it cannot be used without burden in daily life (Patent Document 7).

  Therefore, there is a need for a means for strengthening pelvic floor muscles that can correctly contract pelvic floor muscles without accompanying vaginal insertion and that can be used without burden in daily life.

  On the other hand, various proposals have been made for the purpose of training effect by elastic expansion / contraction of the elastic piece by simply attaching it to the body by bonding a band-like elastic piece to the constituent surface of clothing such as spats and training pants.

  For example, the garment shown in Patent Document 8 aims at strengthening the strength of the thigh adductor muscle group or the buttocks abductor which is difficult to increase the muscle strength by training. It is the structure provided in the place. And it is going to assist reinforcement | strengthening or the maintenance of the target muscle | muscle by this strong elongation strip | belt-shaped member.

  The girdle shown in Patent Document 9 is intended for the treatment of lower back distortion, lower back pain, and O-leg, and includes a front elastic band extending along the adductor muscle and a back elastic band provided to lift the gluteus medius. The structure is provided. And it is supposed that the effect of forging muscles is demonstrated by the elasticity of the elastic band.

  The garment (spats) shown in Patent Document 10 supports the movement of muscles and joints of the lower limbs, and aims to suppress the movement of the center of gravity with respect to the body axis that causes accumulation of fatigue and O-legs. The belt-shaped member passing through the greater gluteus and mid gluteus has a strong tightening force. The two right and left belt-like members intersect each other with a greater trochanter, whereby the greater trochanter is pressed with a strong tightening force to suppress inward and outward rotation and prevent the center of gravity from being shaken.

Japanese Patent Laid-Open No. 63-281626 Japanese Patent No. 3472551 JP 2008-297 A JP 2001-104515 A Utility Model Registration No. 3139627 Utility Model Registration No. 3117998 Japanese Patent No. 4372225 JP 2005-36353 A Japanese Patent No. 4493447 JP 2006-321221 A

  In this way, as for the purpose of strengthening the pelvic floor muscles, the pelvic floor muscles can be contracted correctly without insertion of the vagina, and there is a need for something that can be used without burden in daily life. There is no appropriate means. In addition, clothing intended for the training effect has a structure using a band-shaped elastic piece provided for muscles intended for reinforcement, and aims to reinforce the target muscle mainly by the tension action by the band-shaped elastic pieces. However, it does not show anything about strengthening of the pelvic floor muscles and means therefor.

  An object of the present invention is to provide a means for strengthening pelvic floor muscles that can solve these problems of the prior art, can contract the pelvic floor muscles correctly without involving vaginal insertion, and can be used without burden in daily life. And

  As a result of intensive studies to achieve the above object, the present inventor has provided an extensible belt-like structure having tensile elasticity on the girdle, so that the girdle wearer can be given a group of adductor muscles (particularly the adductor upper portion). The present inventors have found that the pelvic floor muscles can be contracted by applying a load to the pubic muscle, etc., and the present invention has been completed. According to the girdle based on this knowledge, the pelvic floor muscles can be strengthened only by wearing the girdle by the operation of the daily activity level.

  That is, the present invention has a body part that forms a body part that covers the waist part of the wearer and a pair of legs branched from the crotch part so as to cover the thigh part of the wearer, and has a tensile elasticity in the longitudinal direction. A pair of left and right extensible belt-like structures extending over at least a part of the trunk and the leg, and each of the pair of extensible belt-like structures includes a portion adjacent to the crotch bottom in the inner portion of the pair of legs. The lifting structure is a lifting structure that extends from the working area to the front body side and ascends to at least the side of the trunk or leg, and the lifting structure places a load on the adductor muscle group in the mounted state. The present invention provides a girdle characterized in that the pelvic floor muscles contract by being applied.

  The pull-up structure can apply a load in a direction in which the toe side rotates while being separated from the other foot with the heel as a fulcrum with respect to the adductor muscle group.

  It is preferable that the lifting structure has a length dimension from the crotch of the wearer to ¼ to 1/2 of a length dimension from the crotch to the medial epicondyle of the femur in the action region.

  Further, the present invention has a body part that forms a torso covering the waist of the wearer and a pair of legs branched from the crotch part so as to cover the thigh of the wearer, and has a tensile elasticity in the longitudinal direction. A pair of left and right extensible belt-like structures extending over at least a part of the trunk and the leg, and each of the pair of extensible belt-like structures includes a portion adjacent to the crotch bottom in the inner portion of the pair of legs. There is provided a girdle for pelvic floor muscle training characterized in that it has a working structure and a lifting structure that extends from the working region to the front body side and ascends to at least the side of the trunk or leg.

  In this case as well, the lifting structure can apply a load in a direction in which the toe side of the foot is rotated away from the other foot with the heel serving as a fulcrum.

  Moreover, in the said action | operation area | region, it is preferable that the length dimension from a crotch of a wearer is 1/4 to 1/2 of the length dimension from a crotch to a femoral medial epicondyle.

  ADVANTAGE OF THE INVENTION According to this invention, the pelvic floor muscle can be correctly contracted without accompanying a vagina, and the reinforcement means of the pelvic floor muscle which can be used without a burden in daily life can be provided.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The same or similar parts in the drawings are denoted by the same reference numerals and description thereof is partially omitted.

[Example of basic configuration]
FIG. 1 shows a girdle (girdle for pelvic floor muscle training) according to an embodiment of the present invention, wherein (a) is a front view and (b) is a rear view. 2 shows the back of the girdle of FIG. 1, (a) is a front view, (b) is a rear view, FIG. 3 shows a state where the girdle of FIG. 1 is attached to the body, and (a) is a front view. (B) is a side view, (c) is a rear view.

  The pelvic floor muscle training girdle 1 includes a body portion 10 that covers a waist portion of the wearer, and a main body portion 10 that includes a pair of legs 12 branched from the crotch bottom portion so as to cover the thigh portion of the wearer, and a longitudinal direction. And a pair of left and right extensible belt-like structures 30 (band-like tightening structures) having tensile elasticity and extending over at least a part of the body and legs.

  The extensible belt-like structure 30 is provided in the front body 1a. The extensible belt-like structure 30 is sewn on the back surface of the girdle 1, and only the stitch 31 appears on the front surface. In this embodiment, the main body portion 10 constituting the entire surface of the girdle 1 is made of a stretchable mesh fabric (so-called power net) made of 83% nylon and 17% polyurethane. It is made of a rubber band fastening material formed as a two-way stretch tape made of 75.4% nylon and 24.6% polyurethane. Various other materials can be selected according to the size, application, quality, degree of training effect, etc. of the girdle. The stretchability of the material of the main body unit 10 is determined so as to exhibit a body fitting function and a tightening function. The stretchability of the extensible belt-like structure 30 is determined so as to exhibit elasticity stronger than that of the main body portion 10, and is determined so that an appropriate load is applied to the adductor muscle described below.

  The extensible belt-like structure 30 has a portion adjacent to the crotch bottom portion 15 in the inner portion of the pair of leg portions 12 as an action region 35, extends from the action region 35 to the front body 1 a side, and rises. Further, as shown in FIG. 3B, a lifting structure 40 whose end portion reaches the back of the body in the mounted state is formed. This side portion is a portion corresponding to a greater trochanter (see P2 in FIG. 3B) of the person when the girdle is attached. As shown in FIG. 2B, in the pulling structure 40, the upper edge 17 a is located on the trunk 11 and the lower edge 17 a is located on the trunk 11 at the outer edge 16 of the girdle. . An intermediate region 13 is formed at the center of the body 11 in the front body 1a. The intermediate region 13 is formed of a flexible material or structure so that the pressure on the wearer does not increase, and the front body 1a does not press the bulge of the wearer's abdomen. . It also includes the case where there is no intermediate region and the tensile force can be transmitted through the material or structure of the main body.

  As shown in FIG. 3A, the lifting structure has a length dimension from the crotch of the wearer to ¼ of the length dimension from the crotch to the medial epicondyle of the femur, as shown in FIG. Yes. That is, when a wearer (for example, a person having an average height of a Japanese woman) wears the girdle of the present invention, the lower edge 17b of the lifting structure 40 is 1/0 from the crotch to the medial epicondyle of the femur. 4, the pulling structure 40 covers from the crotch to this place. As shown in FIG. 4, when the length dimension from the human crotch to the femoral medial epicondyle is L, the pubic muscle is usually present from the crotch to L / 4. Therefore, the lifting structure 40 covers the wearer's pubic muscle or the vicinity thereof by setting the length of the action region 35 to L / 4 from the crotch.

  As shown in FIG. 5, the crotch part 15 refers to the innermost part (the part closest to the trunk part) of the curved line Lin on the inner side of the pair of legs, and the action region F corresponds to the inner part of the pair of legs. The part adjacent to the crotch part 15 is said. The crotch part can be approximately the part located at the innermost part of the inner curve line of the pair of leg parts when the girdle is placed flat so that the front and rear parts overlap each other. . The range of the working area is a range that accepts the width of the extensible belt-like structure required for the function of the girdle according to the present invention. Further, the “part adjacent to the crotch part” includes not only the area F1 in contact with the crotch part 15 but also a neighboring area F2 spaced from the crotch part 15 in the leg extending direction and / or in the direction crossing the leg part. .

  The pelvic floor muscle training girdle 1 according to this embodiment is used in the following manner and exhibits an effect.

  The girdle 1 is attached to the body as usual as shown in FIG. In this mounted state, the lifting structure 40 extends from the action region 35 toward the front body 1a and goes up around the side portion of the girdle while rising. Thereby, the raising structure applies a load to the adductor muscle group. According to the inventor's knowledge, the pelvic floor muscles can be contracted through this load, as is apparent from the following experimental examples. As a result, if the girdle 1 is worn, the pelvic floor muscles can be strengthened by an operation of the daily activity level.

  In other words, the elastic force acting on the action region 35 acts in a direction in which the toe side of the foot rotates around the heel as a fulcrum while being separated from the other foot, as will be apparent from an experimental example described later (hereinafter referred to as the following example). Called external rotation). In many cases, the wearer tries to unconsciously return, that is, the heel is rotated while the toe side of the foot is close to the other foot (hereinafter referred to as internal rotation). Along with this internal rotation, a load is applied to the adductor muscle group. The adductor muscle group (especially the short adductor and pubic muscle located in the upper part) is close to the pelvic floor muscles, and the pelvic floor muscles are indirect by applying a load to the adductor muscle group by internal rotation. It is thought that it can be shrunk. Therefore, by using the girdle of the present invention, the pelvic floor muscles can be contracted, and the pelvic floor muscles can be strengthened by operations of the daily activity level. Moreover, since the girdle of the present invention indirectly applies a load to the pelvic floor muscles, it does not place an excessive burden on the pelvic floor muscles. Thereby, since fatigue of the pelvic floor muscles can be prevented, the burden on the wearer is eased and it becomes easy to use for a long time.

  Furthermore, in this embodiment, the raising structure 40 has a length dimension from the crotch to L / 4 in the action region, and covers the pubic muscle. Therefore, the pulling structure 40 can increase the contact pressure particularly in the vicinity of the pubic muscle, and can effectively load the pubic muscle. In this way, the girdle of the present invention can effectively contract the pelvic floor muscles, and the strengthening action by this can be reliably obtained.

  In this way, according to the pelvic floor muscle training girdle according to the present embodiment, the pelvic floor muscle can be properly strengthened while wearing the body and spending daily life without burden.

  The lifting structure 40 only needs to extend to at least the side portion (the portion corresponding to the greater trochanter), and the end portion of the lifting structure 40 may not reach the back body 1b in the mounted state. . Moreover, when the raising structure 40 reaches the back body 1b, it is good also as what has an extension part which extends the back body 1b further. For example, as shown in FIG. 6A, the end of the extended portion is located in the rear body 1b, and the extended portion of each pulling structure 40 can be discontinuous. Moreover, as shown in FIG.6 (b), it is good also as what is extended so that the extension part of each raising structure 40 may become a mountain shape in the center of a back part. As shown in FIG. 6C, the end portion of the extended portion of each pulling structure 40 may be located at the opening of the trunk portion 11. Furthermore, as shown in FIG. 6D, the extended portions of the respective lifting structures 40 may be continuous so as to form a single straight line at the center of the back portion.

  The inclination angle of the pulling structure 40 can be various as shown in FIG. That is, as shown in FIG. 7 (a), in the outer edge 16 of the girdle, the upper edge 17a is located on the body 11, and the lower edge 17b is located on the leg 12. As shown in (b), in the outer edge portion 16, the upper end edge 17 a is positioned on the leg portion 12, and the lower end edge 17 b is positioned on the leg portion 12.

  Further, in addition to a pulling structure 40 for pulling up the front surface (hereinafter sometimes referred to as a front pulling structure), a rear pulling structure 50 or a thigh spiral structure 70 as shown in FIG. 8 may be provided. That is, as shown in FIG. 8A, the rear surface lifting structure 50 is adjacent to the front surface lifting structure 40 in the action region 35 and extends from the action region toward the back body 1b and goes up around the side portion of the girdle. . As shown in FIG. 8 (b), the front pulling structure 40 is coupled to each other so that a tensile force based on elasticity can be transmitted in the rear body 1b. Further, as shown in FIG. 8A, the rear surface lifting structure 50 is coupled to each other so that a tensile force based on elasticity can be transmitted in the front body 1a. The pair of rear surface lifting structures 50 are coupled to each other so as to transmit a tensile force based on elasticity through the intermediate region 13 described above. Regarding the front pulling structure and the rear pulling structure, the pair of pulling structures are "coupled to each other so that a tensile force based on elasticity can be transmitted" means that the pair of pulling structures is connected directly. In the latter case, it is only necessary to be able to transmit a tensile force based on elasticity through the combined reinforcing structure. It also includes the case where there is no intermediate region and the tensile force can be transmitted through the material or structure of the main body.

  Further, when the rear surface lifting structure 50 is provided, the peripheral ends of the pair of rear surface lifting structures 50 are coupled to each other through the middle region 13 at the front body 1a, and the upper end of the front surface lifting structure 40 is connected to the rear surface lifting structure 50 at the front body 1a. (It may be a form like the specimen 3 in an experimental example described later). As described above, the “surrounding” of the front lifting structure includes the coupling at the side of the front lifting structure and the rear lifting structure.

  Thereby, the rear surface raising structure 50 acts to raise the buttocks, can apply a load to the anal sphincter, and can contract the pelvic floor muscle through this. With such a configuration, by wearing the girdle 1, the pelvic floor muscles can be further strengthened by an operation of a daily activity level.

  The thigh spiral structure 70 circulates around the side of the girdle while extending downward from the action region 35 toward the front body 1a. The thigh spiral structure 70 acts to promote contraction of the pelvic floor muscles during the abduction motion of the leg, as will be apparent from experimental examples described later. Therefore, the wearer of the girdle can strengthen the pelvic floor muscles by consciously or unconsciously repeatedly performing an operation involving external rotation.

[Experimental example]
Next, an experimental example in which the inventor has found a relationship between the load on the adductor muscle and the contraction of the pelvic floor muscle will be described. The specifications of the girdle used in the experiment and its performance evaluation are described below.

(1) Schematic diagrams of specimens used in the girdle specification experiment are shown in FIGS. 9 to 11, and specifications (structural elements) of each specimen are shown in Table 1, and the details will be described. The items in the table indicate the following specifications.

“Hardly extensible structure”: a structure that hardly undergoes elastic deformation against a tensile force, and is provided in the crotch portion adjacent to the action region. For example, the front pulling structure 40 overlaps with an extensible structure made of the same material in a portion adjacent to the action region 35, and the overlapping portions overlap each other and have different tensile elastic directions, so that the tensile force is increased. On the other hand, it is difficult to deform.
“Back center suture”: Bonding at the back of the front lifting structure.
“Thigh spiral structure”: A structure that spirals around the side of the girdle while descending from the action area toward the front body.
“Body material”: A material of the main body forming the trunk and legs of the girdle.
“Mesh”: 83% nylon, 17% polyurethane material (Toyobo Espa Powernet T7381)
"Glossy": Material made of 80% nylon and 20% polyurethane (nylon 2WAY T6008)

These couplings are performed so that the front pulling structure and the rear pulling structure can transmit a tensile force based on the elasticity of the structure to each other. The intermediate region 13 has a tensile elastic modulus equivalent to or lower than that of the main body 10 so that the pressure on the wearer does not increase (the same applies to the following specimens).

(2) Performance evaluation The following performance evaluation was performed on the above samples.
(2-1) Sensory evaluation Sensory evaluation: All the samples were applied to seven women, and the average value of the numerical values obtained by evaluating the wearing feeling in five levels was obtained.
(2-2) After fixing the pressure measurement probe to the pressure mannequin, the specimen was placed and the pressure at each site was measured.
Equipment used: Handy contact pressure gauge Measurement sites made by AIM Techno Co., Ltd .: Sites indicated by P1 to P8 in FIG. However, in the following evaluation results, only the abdominal wearing pressure P1 and the crotch wearing pressure P4 that have been predicted to be related to the contraction of the pelvic floor muscles as the experiment progresses are described.
(2-3) A myoelectric electromyograph was attached, and the myoelectric potential was measured when various exercises were performed with the girdle of the specimen from above. Since the electromyograph is worn in the vagina, the measured value clearly reflects the strength of the pelvic floor muscle strength.
Equipment used: Femiscan clinic system specifications (sales agency: Medical Task Force)
Measurement conditions: Muscle contraction force in the following movements: Resting, normal walking, walking on the crotch, normal standing, standing on the inner crotch, abduction, outward turning motion, inward turning motion, FIG. 12 shows the states of a) crotch walking, (b) crotch walking, (c) abduction, (d) outward turning motion, and (e) inward turning motion.

(3) Evaluation results Table 2 shows the sensory evaluation and pressure evaluation results, and Table 3 shows the myoelectric potential evaluation results.

In order to compare the influence of the specifications (structural elements) of specimens 1 to 6 on the evaluation items (sensory evaluation, wearing pressure, myoelectric potential), regression analysis is performed, and multiple correlation R, coefficient, and P-value are calculated. Asked. The results are shown in Tables 4 and 5.

  Regarding the above relationship, the results of the sensory evaluation in Table 4 cite “inseam tightness”, “outer crotch effect”, and “vaginal tightness” as sensory evaluation items corresponding to the contraction of the pelvic floor muscles. The specifications (structural elements) having a high correlation with these items are “pickup structures”, and in particular, it has been confirmed that the front pulling structure has a high correlation with these items.

FIG. 13 is a graph showing the results of tabulating the effects of the actions on pelvic floor muscle contraction based on Table 3. From FIG. 13, the following relationship can be derived.
(a) Normal walking and turning motion of the foot are particularly strong and promote the contraction of the pelvic floor muscles. In particular, the outward turning motion promotes the contraction of the pelvic floor muscles more strongly than the inward turning motion.
(b) Even in a standing position, pelvic floor muscle contraction is promoted when conscious that force is applied to the inner thigh.

  FIG. 14 is a graph showing the results of tabulating the myoelectric potential (measured by insertion into the vagina) and the crotch landing pressure (pressure in the hardly stretchable structure) measured in this experiment based on Table 3. From this graph, Samples 1 to 6 clearly show higher values in both myopotential and crotch pressure compared to Comparative Sample 1 and the blank. Table 5 shows a high correlation between myoelectric potential and inseam pressure. The myoelectric potential corresponds to the degree of contraction of the pelvic floor muscles, and the crotch pressure corresponds to the load on the adductor muscles. That is, even when the pull-up structure is provided at least on the front surface like the specimen F, the high pull-up structure on the front surface exerts a load on the adductor muscle group and promotes the external rotation movement. It was found to affect the contraction of pelvic floor muscles. Therefore, it can be said that the above correlation indicates that the pelvic floor muscles can be contracted if a load is applied to the adductor muscles, and this is the finding that led to the completion of the present invention.

  As mentioned above, although embodiment of this invention and the experiment example were demonstrated, this invention is not limited to this, A various change is possible unless it deviates from the meaning. For example, the hardly extensible structure can be formed by other members that are difficult to elastically deform against a tensile force.

  In the working region, the length structure from the crotch of the wearer may be 1/3 of the length dimension from the crotch to the medial epicondyle of the femur. Short adductor muscles usually exist from the crotch to L / 3 (see FIGS. 3 and 4). Accordingly, the lifting structure covers the short adductor of the wearer (for example, a person who has an average height of a Japanese woman) or the vicinity thereof by setting the length in the action area to L / 3 from the crotch. Therefore, the contact pressure in the vicinity of the short adductor can be increased, and a load can be effectively applied to the short adductor.

  In the working area, the length structure from the crotch of the wearer may be ½ of the length dimension from the crotch to the medial epicondyle of the femur. The adductor muscle group exists from the normal crotch to L / 2 (see FIGS. 3 and 4). Therefore, the lifting structure covers the adductor muscle group of the wearer (for example, a person having an average height of a Japanese woman) or the vicinity thereof by setting the length of the action region to L / 2 from the crotch. Therefore, the contact pressure in the vicinity of the pubic muscle can be increased, and the load can be effectively applied to the pubic muscle.

  In the embodiment and the experimental example, the extensible belt-like structure 30 is sewn on the back surface of the girdle 1, but the extensible belt-like structure 30 may be sewn on the surface of the girdle 1, It is also possible to sew on both the front and back surfaces. In addition to the girdle, the subject of the present invention can also be underwear such as spats, tights, pantyhose, body suits, trousers and the like.
