Description

  The present invention relates to a girdle, particularly a girdle advantageous for use as a pelvic floor muscle training girdle for training the pelvic floor muscle by wearing it on the body.

  As shown in FIG. 10, 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. Oral explanation alone is not sufficient for mastering pelvic floor muscle exercises, and it may be necessary for the instructor to recognize the position of the pelvic floor muscles while performing an intravaginal examination and convey the correct contraction method. Difficulties accompany implementation in terms of sex and psychological resistance.

  There are methods such as biofeedback therapy and intravaginal cone as a way to learn the correct pelvic floor muscle contraction method and motivation to continue exercising. Absent.

  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 (see FIG. 11) or the abductor abductor, which is difficult to increase the muscular strength by training. It is the structure which provided in these stripe applicable parts. 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.

  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 includes a body part that covers a waist part of a wearer and a body part that forms 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. A front lifting structure that extends from the working area to the front body side and circulates to at least the side of the trunk, and is adjacent to the front lifting structure in the working area and from the working area to the rear body side. And a rear surface lifting structure that circulates and rises to at least a side portion of the body portion, and the extensible band-shaped structure includes the pair of front surface lifting structures and the pair of rear surface lifting structures. The girdle is characterized in that the circumferential end portions of each other or the front pulling structure and the rear pulling structure are coupled so as to transmit a tensile force based on the elasticity of the structure to each other. is there.

  The pair of front pull-up structures may extend to the back of the trunk and be coupled so that a tensile force based on the elasticity of the structure can be transmitted between the back of the body.

  The pair of rear surface lifting structures may be connected to each other so as to extend to the front body of the body portion and transmit a tensile force based on the elasticity of the structure between the front body and the body.

  The pair of front pulling structures and the pair of rear pulling structures respectively extend to the side portions of the body portion, and in the side portions, one of the front pulling structure and the rear pulling structure of the pair, and the other of the pair of the pair. The front lifting structure and the rear lifting structure may be coupled so that a tensile force based on the elasticity of the structure can be transmitted between them.

  A hardly extensible structure that is difficult to be elastically deformed by a tensile force can be formed in the action region of the leg portion and its vicinity.

  The hardly extensible structure may be formed in the vicinity of the action region in the front pull-up structure.

  The stretchable belt-like structure may further include a thigh spiral structure that goes around the left and right half portions of the girdle while descending from the working region toward the front body side.

  The hardly extensible structure may be formed by an overlapping portion of the front pull-up structure and the thigh spiral structure in the vicinity of the action region.

  In the front pulling structure, a rising angle extending while rising from the working area may be larger than the rear pulling structure.

It is a longitudinal front view which shows the skeleton and muscles of a human body centering on the adductor muscle.

  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 according to an embodiment of the present invention, particularly a girdle that is advantageously used for pelvic floor muscle training, 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 girdle 1 includes a body portion 10 that covers a waist portion of the wearer and a pair of legs 12 branched from the crotch portion so as to cover the thigh portion of the wearer, and has a tensile elasticity in the longitudinal direction. And a pair of left and right extensible belt-like structures 30 (band-like tightening structures) extending over at least a part of the body and legs.

  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.

  Each of the extensible belt-like structures 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, and extends from the action region 35 toward the front body 1a side and rises to the left and right half of the girdle. A front lifting structure 40 that circulates around the portion, and a rear surface lifting structure 50 that is adjacent to the front lifting structure 40 in the action region 35 and extends from the action region toward the rear body 1b and rises around the left and right half portions of the girdle. ing.

  As shown in FIG. 2B, the front lifting 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. 2A, the rear pull-up structure 50 is coupled to each other so that a tensile force based on elasticity can be transmitted in the front body 1a. 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. . The pair of rear surface lifting structures 50 are coupled to each other through the intermediate region 13 so as to transmit a tensile force based on elasticity.

  Regarding the front pulling structure and the rear pulling structure, the pair of pulling structures are “coupled so as to transmit tensile force based on elasticity between each other” when the pair of pulling structures are directly coupled In addition, including the case where the intermediate region 13 or the like is interposed between them, in the latter case, it is only necessary to be able to transmit a tensile force based on elasticity through the combined region. 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. 4, the crotch bottom portion 15 is the innermost portion (the portion closest to the trunk portion) of the curved line Lin inside the pair of legs, and the action region F (F1, F2) is the pair of legs. The part adjacent to the crotch bottom part 15 in the inner part of a part 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. . In this embodiment, the front raising structure 40 and the rear raising structure 50 are adjacent to each other in the action region F3 located on the stitch line 14 for sewing the front body 1a and the back body 1b.

  In the embodiment shown in FIGS. 1 and 2, the extensible strip structure 30 further comprises a thigh spiral structure 70 on each of the pair of legs. Each thigh spiral structure 70 is provided so as to go around the left and right half portions of the girdle while extending downward from the action region 35 toward the front body 1a.

  The girdle 1 according to this embodiment is used as follows and exhibits the effect.

  The girdle 1 is attached to the body as usual as shown in FIG. In this mounted state, the front lifting structure 40 extends from the action region 35 to the front body 1a side and rises while turning around the left and right half portions of the girdle. Thereby, the front 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.

  Further, the rear surface lifting structure 50 extends from the action region 35 to the rear body 1b side and goes up around the left and right half portions of the girdle while ascending. As a result, the rear pull-up structure acts to pull up the buttocks, thereby applying a load to the anal sphincter and allowing the pelvic floor muscles to contract through this. Also in this respect, if the girdle 1 is worn, the pelvic floor muscles can be strengthened by the operation of the daily activity.

  Further, the front lifting structure 40 and the rear lifting structure 50 are adjacent to each other in the action region 35. By this adjacency, the load action on the adductor muscle group and the buttocks pull-up action are concentrated in the action area 35, and the reinforcement of the muscle based on the load is effective.

  The elastic force acting on the action region 35 thus acts in the 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 the experimental examples described later (hereinafter, 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.

  In particular, the extensible belt-like structure 30 is based on the elasticity of the circumferential ends of the pair of front lifting structures 40, the circumferential ends of the pair of rear lifting structures 50, or the front lifting structure 40 and the rear lifting structure 50. Since they are connected to each other so that a tensile force can be transmitted, the extensible belt-like structure 30 is a spiral ring that is substantially closed in a range from the working region 35 to the connecting portion through the front pulling structure 40 or the rear pulling structure 50. Extend to draw. As a result, the pulling force of the front pulling structure 40 and the rear pulling structure 50 and the accompanying pressure on the crotch part are secured without being released, and the load on the adductor muscle acts effectively, and the pelvic floor The strengthening effect by the contraction of the muscle can be surely obtained.

  Thus, according to the girdle according to the present embodiment, the pelvic floor muscles can be strengthened correctly while wearing the body and spending daily life without burden.

  Furthermore, in this embodiment, the extensible belt-like structure 30 is provided with a thigh spiral structure 70 that goes around the left and right half portions 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 movement of the leg, as will be apparent from experimental examples to be described later. Further strengthening of the rear pulling structure 50 is performed.

(2-1) Sensory evaluation Sensory evaluation: All samples were applied to seven women, and the average value of the numerical values obtained by evaluating the wearing feeling in five levels was determined.
(2-2) After fixing the pressure measurement probe to the pressure mannequin, the specimen was placed, and the pressure applied at each part was measured. Equipment used: Handy contact pressure gauge Measurement parts made by AIM Techno Co., Ltd .: Inseam, abdomen, buttocks , Sites shown in P1 to P8 of 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.

Equipment used: Femiscan clinic system specifications (sales agency: Medical Task Force)
Measurement conditions: Muscle contraction force in the following movements: resting position, normal walking, gait walking, normal standing, standing in the inner crotch, abduction, outward turning motion, inward turning motion.
Among these, FIG. 8 shows the states of (a) normal walking, (b) crotch walking, (c) abduction, (d) outward turning motion, and (e) inward turning motion. These operations were adopted as measurement conditions from the following viewpoints. That is, of the above movements, during normal walking, walking in the crotch, normal standing, standing in the inner crotch, abduction, outward turning movement, inward turning movement, with the girdle attached, the level of daily life By repeating this operation, it was adopted as an operation that has a training effect and can acquire or improve effects such as incontinence prevention. Of the above operations, the resting position is adopted as an operation that can immediately acquire or improve effects such as prevention of incontinence by the action of the girdle by wearing.

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

From Table 5, the following relationship can be derived.
(a) In order to strengthen the voluntary contraction force of the pelvic floor muscles in the resting position, the “front lifting structure + rear lifting structure”, “difficult structure” and “inseam pressure” are effective.
(b) In order to promote involuntary contraction of the pelvic floor muscles due to walking, the “front lifting structure + rear lifting structure”, “difficult to stretch structure” and “inseam pressure” are effective.
(c) In order to promote involuntary contraction of the pelvic floor muscles due to standing and abduction, “front lifting structure + rear lifting structure”, “difficult structure”, “thigh spiral structure” and “inseam pressure” Is effective.

  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. Specifications (structural elements) that have a high correlation with these items are “front lifting structure + rear lifting structure”, “difficult to stretch structure”, and “thigh spiral structure”, and the above relationship corresponds well with sensory evaluation. It was confirmed.

  FIG. 9 is a graph showing the myoelectric potential (measured by insertion into the vagina) and the crotch pressure (pressure in the hardly stretchable structure) measured in this experiment. From this graph, Samples 1 to 4 clearly show higher values in both myopotential and crotch pressure compared to Comparative Sample 1 and the blank. In addition, myoelectric potential and crotch pressure are highly correlated. 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. 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.

  The girdle 1 is presumed to act as follows based on the correlation between the myoelectric potential and the crotch pressure. The inseam pressure (pressure in the hardly stretchable structure) includes a front pulling structure that extends from the action area to the front body side and circulates while rising, and is adjacent to the front pulling structure in the action area from the action area to the back body side. It is given by the rear surface lifting structure that extends and rises and circulates. Therefore, the crotch landing pressure acts to pull the wearer's thigh outward in the action region 35. On the other hand, the wearer often unconsciously tries to close the thigh inside. Along with this, a load is applied to the adductor muscle group of the wearer, and the pelvic floor muscles are strengthened through this.

  In particular, as shown by the specimens 1 to 4, the extensible belt-like structure 30 is formed by the peripheral ends of the pair of front surface lifting structures 40, the peripheral end portions of the pair of rear surface lifting structures 50, or the circulation of the front surface lifting structure 40. The end portion and the circumferential end portion of the rear surface lifting structure 50 are coupled to each other so that a tensile force based on elasticity can be transmitted. Therefore, the extensible belt-like structure 30 extends so as to draw a substantially closed spiral ring in a range from the action region 35 through the front pulling structure 40 or the rear pulling structure 50 to the coupling point. As a result, the pulling force of the front pulling structure 40 and the rear pulling structure 50 and the accompanying pressure on the crotch part are ensured without being released. As a result, the load on the adductor muscles acts effectively, and the strengthening action due to the contraction of the pelvic floor muscles is surely obtained. Thus, according to the girdle 1 according to the present embodiment, the pelvic floor muscles can be properly strengthened while wearing the body and spending daily life without burden.

  Furthermore, since the hardly stretchable structure 60 that hardly elastically deforms against the tensile force is formed in the action region 35 and its vicinity, the tensile force of the front pulling structure 40 or the rear pulling structure 50 is difficult to stretch. In the structure 60, it effectively acts as a pressure for pressing the crotch part.

  When the hardly stretchable structure 60 is formed on the front body 1a side from the action region 35, the inclination angle at which the front lifting structure 40 extends from the action region 35 is larger than the inclination angle of the rear surface lifting structure 50. It is considered desirable. This is because the force that acts to pull the thigh of the wearer outward in the vicinity of the action region 35 and its front body 1a side is more effectively exhibited by the front lifting structure 40.

  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 stretchable structure is formed by overlapping the front pulling structure and the thigh spiral structure as in the above example, and it is difficult to elastically deform against the tensile force regardless of the presence or absence of the thigh spiral structure. It can also be formed by these members. For example, the hardly extensible structure can be formed by joining a member that is not elastically deformed with respect to a tensile force, overlapping or replacing the corresponding part of the main body part, or the corresponding part of the main body part. Can be formed by restraining with a sewing thread such as a sewing machine.

  In addition, for the structure in which the extensible belt-like structures are coupled to each other so that a tensile force based on elasticity can be transmitted, the circumferential ends of the pair of front lifting structures or the circumferential ends of the pair of rear lifting structures are In addition to the coupling, the front lifting structure and the rear lifting structure may be coupled. In this case, the circumferential end portion of the front lifting structure and the circumferential end portion of the rear lifting structure are coupled (for example, FIG. ), (6)), one of the front lifting structure and the rear lifting structure is coupled to the other intermediate portion, or each intermediate portion of the front lifting structure and the rear lifting structure is coupled to each other. Can take form.

  The extensible strip structure can be provided on the surface of the girdle instead of being provided on the back surface of the girdle as shown in the embodiment, or can be provided so as to be mixed on the back surface and surface of the girdle. 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.
