Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a perineal gymnasium which can be used mainly for perineal gymnastics for preventing and treating urinary incontinence in women.

[0002]

2. Description of the Related Art Generally, a method of strengthening muscles such as limbs and trunk, which are visible on the surface of the body, a strengthening device, and their effects are well known. On the other hand, a part that is not visible on the body surface, especially a method for strengthening muscles in the pelvic cavity, a training device, and its effect are not well known. This is traditionally less talked about in terms of sex,
It can be said that it was because the research was not openly conducted on the soil.

In recent years, awareness of urinary incontinence has improved significantly. The reason for this is that in addition to the enormous medical costs involved, leaving urinary incontinence as a hotbed for the bedridden old man will cause pain not only to himself but also to his / her family. . Urinary incontinence, if simply defined, refers to a state where urine leaks at any time and place against your will, and there are the following types.

Urinary incontinence is a type that has a strong desire to urinate and cannot endure until going to the toilet. Overflow urinary incontinence This is a type in which a small amount of urine constantly overflows without urinating even though the bladder is full of urine.

Stress urinary incontinence When you sneeze or cough, laugh, lift something,
This is a type in which a small amount of urine leaks out when jogging or when an abdominal pressure exceeding the function of closing the urethra is applied. Complete urinary incontinence This is a type with complete lack of urine retention control.

Enuresis A type of so-called bedwetting (enuresis) in the state where excretion of urine at night cannot be controlled. As described above, there are various types of urinary incontinence, but it can occur in any age group regardless of race or gender, regardless of gender. There are more women than men in adolescents and middle-aged men, and it is estimated that 8 to 25 percent of the sanitary napkins purchased are used for urinary incontinence rather than menstruation.

By the way, as the cause of urinary incontinence,
Pelvic floor muscles damage due to multiple deliveries, surgery of pelvic organs, spinal cord injury, congenital defects of the spinal cord, bacterial infection of the bladder, stroke, conditions such as obesity and diabetes or side effects of drugs, etc. Can be mentioned. However, urinary incontinence is not an illness, but a symptom with various causes in the background. Urinary incontinence causes anxiety in many people and limits their behavior. Patients are often therefore hindered from their work,
I can't go on a trip and even get out of my home. However, because of their awkwardness, patients often do not seek to discuss their urinary incontinence with anyone, even their doctor. But it is also true that there are many cures for urinary incontinence. The first step in treating urinary incontinence is to know the type.

Among the various urinary incontinences mentioned above, the most predominant one is stress urinary incontinence, especially in adult women.
Roughly speaking, about one in three adult women, including those with sudden onset, experience more or less urinary incontinence. Of these, the number of cases in which treatment is particularly necessary is estimated to be about 10%, which is a huge number.

Among them, stress urinary incontinence is particularly common in middle-aged and multiparous women, and anatomically, in women with weak or weak sphincter function. The cause of this is that the pelvic floor muscle group becomes relaxed due to trauma during labor and atrophy of the urethral mucosa and supporting tissues around it due to menopause and aging. Originally, the pelvic floor muscle group increases the intra-abdominal pressure by acting in cooperation with the abdominal wall muscle, and also maintains the tension of the lower urogenital hiatus to prevent the dropout of pelvic organs. It also works as a support and reinforcement device for organs. The main function of this is the levator ani muscle, and when the levator ani muscle contracts, the rectum and vagina are pulled upward. The external anal sphincter also closes the anus with the help of the levator ani and the contraction of the levator ani not only pulls the vagina upward but also pulls the posterior wall of the vagina toward the pubic symphysis. The lumen is narrowed. On the other hand, the bulbar surface body muscles surrounding the urethra and the lower third of the vagina centripetally narrow the vaginal opening and assist the action of the internal bladder sphincter.

That is, the deep perineal muscle, the external urethral sphincter, the urethral vaginal sphincter, etc. are provided around the urethra and vagina, and the sphere sphincter muscle, sciatic surface sphincter muscle, and external anal sphincter muscle further surround these. And shallow perineal transverse muscles. These are referred to as the perineal muscles, and of these, a part of the bulbar surface corpus muscle is intersected at the central fusion point between the external anal sphincter and the vagina and anus to form an 8-shaped shape.

In short, the individual muscles do not work individually as a device for closing the anus, urethra and vagina, but the pelvic floor muscle groups work together, and further, the abdominal wall muscles in the upper part and the muscles in the lower part in the lower part work together. The gluteus maximus will work together. That is, if one muscle is contracted, all other muscles are also contracted. Therefore, paradoxically, strengthening of the pelvic floor muscle group with reduced sphincter function, which is seen in stress urinary incontinence, prevents stress urinary incontinence in adult women and leads to treatment. Is considered to be.

What was devised from this point of view is perineal gymnastics, which is currently practiced in obstetrics and gynecology. In this perineal exercise, a doctor inserts two fingers into the patient's vagina and conducts contraction training of the perineal muscle group while exercising contraction of the perineal muscle group while diagnosing the contractile force. By doing so, the pelvic floor muscle group is strengthened. If this perineal exercise is performed about 100 times a day for about 3 months, the majority of patients with stress urinary incontinence will be cured, except for severe cases.

[0013]

However, the above-mentioned perineal exercises can be said to be a treatment method with great resistance due to the pain of daily visits to the hospital for a long period of time and the shame inherent to women. Therefore, an object of the present invention is to provide a perineal gymnasium capable of performing simple, rational and effective contraction training of the perineal muscle group and strengthening the pelvic floor muscle group without being known to others. Is to provide.

[0014]

The perineal exercise machine according to claim 1 is a gymnastic apparatus for strengthening the pelvic floor muscle group by inserting it into the vagina and performing contraction training of the perineal muscle group. There
It is characterized by having a main body to be inserted into the vagina and a magnetic body provided in the main body and arranged in the vicinity of the perineal muscle group surrounding the vagina at the time of use.

The perineal exercise machine according to claim 2 is the perineal exercise machine according to claim 1, wherein the main body is a rod-shaped member whose outer diameter is smoothly expanded from the proximal end portion to the distal end portion. The base end portion and the tip end portion have a smooth convex shape.

Furthermore, the perineal exercise machine according to claim 3 is the perineal exercise machine according to claim 2, wherein the main body has a total length of 7
0mm, and the maximum diameter of the base end is set to 20mm,
The magnetic body is arranged at a position 30 mm from the tip of the base end, and the outer diameter of the main body at the position where the magnetic body is arranged is set to 25 mm. is there.

Further, the perineal gymnastics apparatus according to claim 4 is the perineal gymnastics apparatus according to any one of claims 1 to 3, wherein a tampon is detachably provided at the tip of the main body. Is. Further, the perineal gymnastics apparatus according to claim 5 is the perineal gymnastics apparatus according to claim 4, wherein the main body is placed along the pubic area with the main body inserted in the vagina, and the displacement of the main body in the vagina is prevented. It is characterized in that a fixing plate is provided.

[0018]

According to the perineal exercise machine according to claim 1, when the main body is inserted into the vagina and force is applied in a manner that tightens the anus, the perineal muscles are contracted, and then the force is released to reduce the perineum. Muscle groups are relaxed. In this way, by contracting or relaxing the perineal muscle group, contraction training of the pelvic floor muscle group interlocking with the perineal muscle group can be performed.

By the action of the magnetic lines of force of the magnetic substance, the hemoglobin (combination of iron and protein) required for transporting oxygen in the blood can be attracted around the perineum. This electromagnetically induces fresh blood containing a large amount of oxygen in muscle tissue and connective tissue with reduced vitality, increases negative ions and improves stagnant blood flow, and activates muscle tissue cells in the perineum. can do.

Further, according to the perineal gymnastics apparatus according to the second aspect, the rod-shaped main body is inserted into the vagina from the distal end portion. Since the tip portion has a smooth convex shape, it can be easily inserted without damaging the vaginal entrance portion. On the other hand, since the proximal end portion also has a smooth convex shape, the body can be easily pulled out from the vagina after the perineal exercise without damaging the vaginal portion.

Further, since the outer diameter of the distal end portion is larger than that of the proximal end portion of the main body, the distal end portion can be stably placed in the vestibular recess of the vagina, and the perineum during perineal exercises. It is possible to prevent the gymnastics from falling off. Furthermore, according to the perineal gymnastics device of claim 3, the total length of the main body is set to 70 mm. From the female anatomical point of view, the length from the vaginal entrance to the posterior vaginal wall is 8 cm to 10 cm on average in Japanese adult women, and the length from the vaginal entrance to the anterior vaginal wall is This is because it is 7 cm to 8 cm. Therefore, it is possible to more stably arrange the distal end portion having the enlarged outer diameter in the vestibular concave portion of the vagina, and it is possible to effectively prevent the perineal gymnastics from falling off during the perineal exercise.

The lower third of the vagina (between about 3 cm from the vaginal entrance) is fixed by the urethral vaginal septum, rectal vaginal septum, urogenital membrane and genital tear, which are pelvic floor muscles. It is surrounded and supported by the group and pelvic connective tissue, which is the confluence of the muscle groups forming the pelvic floor. That is, the pelvic floor muscle groups such as the urethral sphincter, the urethral vaginal sphincter, the anal sphincter and the levator ani muscle close the abdominal cavity at the lower pelvic opening,
In addition, it is a gathering point of muscles that reinforces this, supports the pelvic organ in a normal position, and exerts a function of preventing its dropout. In a Japanese adult woman, the lateral vaginal diameter of the lower third of the vagina is 2 to 3 cm on average.

Therefore, the maximum diameter of the base end of the main body is 20 m.
m, the outer diameter of the main body at a position 30 mm from the tip of the base end is 2
By setting the thickness to 5 mm and arranging the magnetic body at this position, it is possible to effectively carry out the strengthening training of the muscle from the vaginal entrance to the lower third of the vagina. In addition, for adult women such as Westerners and blacks, it is considered anatomically preferable to increase the total length of the main body by 2 cm and the maximum diameter of the proximal end portion by 5 mm.

[0024] According to the perineal gymnasium of the fourth aspect, the tampon attached to the main body absorbs the secretory fluid and the like and expands in the vagina when the main body is inserted into the vagina. This makes it possible to more effectively prevent the perineal gymnastics from falling off, and prevent the perineal gymnastics from getting too deep into the vagina and damaging the inner part of the vagina. further,
According to the perineal exercise machine according to the fifth aspect, since the fixing plate is arranged along the pubic portion in a use state, it is possible to more effectively prevent the main body from being displaced in the vagina.

[0025]

Embodiments will be described in detail below with reference to the accompanying drawings showing embodiments. FIG. 1 is a perspective view of the perineal exercise machine according to the present invention. Referring to FIG. 1, this perineal gymnastics device A is a gymnastic instrument for strengthening the pelvic floor muscle group by inserting it into the vagina and performing contraction training of the perineal muscle group. A pear-shaped main body 10 integrally formed, a tampon 20 attached to the tip 12 side of the main body 10, and a main body 10

An engaging piece 51 is provided at the tip of the so as to project in the radial direction. The engagement pieces 51 are formed at two locations in a state of facing each other in the radial direction of the mounting portion 50.

The dimensions of each part of the main body 10 were determined in consideration of the following points from a female anatomical point of view. In Japanese adult women, the length from the vaginal entrance to the back wall of the vagina is 8 cm to 10 cm on average, and the length from the vagina entrance to the front wall of the vagina is 7 cm to 8 cm.

The lower third of the vagina (about 3 from the vaginal entrance)
cm) between the urethral vaginal septum, rectal vaginal septum, urogenital membrane and genital hiatus, which are surrounded and supported by the pelvic floor muscles and pelvic connective tissue, which is the pelvis. It is a gathering point of the muscle groups forming the bottom. That is, the pelvic floor muscle groups such as the urethral sphincter, the urethral vaginal sphincter, the anal sphincter, and the levator ani muscle close the abdominal cavity at the lower pelvic opening, and
It is a gathering point of muscles that reinforces this, supports the pelvic organs in a normal position, and functions to prevent the dropout. Therefore, strengthening the muscles in this area is effective in preventing and treating urinary incontinence.

The lateral diameter of the vagina in the lower third of the vagina is 2 to 3 cm on average in Japanese adult women. Explaining the dimensions of the main body 10 determined as a result of considering these points, the total length L is set to 70 mm. This allows the perineal gymnastics to be accommodated in the vagina, enabling training with underwear on.

The diameter D1 of the base end portion 11 is set to 20 mm in consideration of the lateral diameter of the vagina in the lower third of the vagina. The outer diameter is smoothly expanded from the base end portion 11 to the tip end portion 12, and the maximum diameter D2 of the tip end portion 12 is set to 34 mm. Accordingly, when the perineal gymnastics is inserted into the vagina, the distal end portion 12 can be stably arranged in the vestibular recess of the vagina, and the perineal gymnastics can be prevented from falling off during the perineal gymnastics. it can.

As a result, effective muscle strengthening can be achieved without damaging the muscle in the lower third of the vagina from the vaginal entrance (about 3 cm from the vaginal entrance). That is, by the action of magnetic lines of force of the magnetic substance, hemoglobin (a combined substance of iron and protein) necessary for transporting oxygen in blood can be attracted around the perineum.
This electromagnetically induces fresh blood containing a large amount of oxygen in muscle tissue and connective tissue with reduced vitality, increases negative ions and improves stagnant blood flow, and activates muscle tissue cells in the perineum. Can be made.

Further, since the base end portion 11 and the tip end portion 12 have a smooth convex shape, they can be safely inserted and removed without damaging the vaginal entrance portion when inserting and removing the perineal exercise machine. Further, FIG. 3 is an enlarged exploded perspective view showing a mounting state of the tampon 20. With reference to FIGS. 2 and 3, the tampon 20 includes a cylindrical base portion 21 and the base portion 2.
1 and an absorbent cotton portion 22 formed at one end thereof. An engaging groove 21a is formed in the base portion 21. The engagement groove 21a has an L-shape cut by a predetermined amount in the axial direction from the other end of the base 21 and is continuously cut by a predetermined amount in the circumferential direction. Are formed in two places facing each other. The engagement groove 21a is engaged with the engagement piece 51 of the mounting portion 50. The tampon 20 absorbs vaginal fluid and the like and expands in the vagina. This makes it possible to more effectively prevent the perineal gymnastics from falling off and prevent damage to the inner part of the vagina when the perineal gymnastics is used.

Further, FIG. 4 is an enlarged sectional view showing a mounting state of the fixing plate 70. Referring to FIGS. 2 and 4, the fixed plate 70 includes a first fixed plate 71 and a second fixed plate 7.
2, and can be opened and closed with respect to the main body 10. That is, in FIG. 1, the fixing plate 70 is in a closed state, and in FIG. 2, it is in an open state. In addition, the first fixing plate 71
The second fixing plate 72 has a predetermined curved surface shape. That is, in use, each of the fixing plates 71,
72 is arranged along the pubic area. This can prevent the body from slipping in the vagina.

Further, FIG. 5 is a view on arrow I in FIG. The hinge structure of the fixing plate 70 will be described with reference to FIG. 5 at the same time. The first fixing plate 71 is formed with a pair of mounting pieces 71a protruding downward.
Has a hole 71b through which the pin 60 is inserted. A pair of mounting pieces 72a similar to the mounting piece 71a is formed on the second fixing plate 72, and the mounting piece 72a is provided with a hole 72b similar to the hole 71b. The pair of mounting pieces 71a are arranged along the pair of mounting pieces 72a on the mounting plate 73. Hole 71 in piece 71a
b, the hole 72b of the mounting piece 72a and the hole 74 of the mounting 73 are penetrated.

Next, a method of using the perineal gymnastics will be described. 1) First, the tampon 20 is attached to the main body 10. In this mounting method, referring to FIG. 3, the mounting portion 50 is covered with the base portion 21 of the tampon 20 so that the engaging piece 51 of the mounting portion 50 and the engaging groove 21a of the tampon 20 are aligned with each other. Then, if the tampon 20 is pushed in along the engaging groove 21a as it is and then turned to the right, the tampon 20 is fixed to the main body 10. In addition, by performing the reverse of the above operation,
The tampon 20 can be removed from the body 10.

2) Open the fixing plate 70 and insert the perineal gymnasium into the vagina from the tip 12 side of the main body 10. At this time, jelly may be applied to the tampon 20 to facilitate insertion. Then, the main body 10 is inserted into the vagina until the fixing plate 70 is arranged along the pubic area. 3) Leave in this state for about 5 to 10 minutes. This is because the tampon 20 absorbs the vaginal fluid and waits for it to expand in the vagina.

4) Wearing underwear and starting perineal exercises by closing and opening the anus. 5) Training Method A training method will be described with reference to FIG. Perform training in each of the following positions. Horizontal supine position This position extends your legs to your back with your hands on the back of your head.

The muscle strengthening sites are the sphincter and abdominal muscles such as the perineum and anus. Horizontal supine knee position In this position, the knees are bent to lie supine, with both hands on the back of the head. The muscle strengthening sites are the sphincter muscles such as the perineum and the anus, and the abdominal muscles. Supine levitation position This position is with the legs extended to the supine position with both hands on the back of the head. At this time, a pillow with a height of 10 cm to 15 cm is applied to the buttocks so that the body is warped.

The muscular strengthening sites are sphincter muscles such as the perineum and anus,
These are the abdominal, gluteus and leg muscles. Supine Standing Knee Position This position is where the knees are bent to lie on their backs, with both hands on the back of the head. At this time, a supporting pillow with a height of 10 to 15 cm is applied to the buttocks, and the buttocks are placed on the supporting pillows so that the knees are in a standing state.

The muscular strengthening sites are sphincter muscles such as the perineum and anus,
Abdominal muscles, gluteus muscles, leg muscles, and psoas muscles. Supine position knee position (without pillow) In this position, the knees are bent to lie on the back, with both hands on the back of the head. At this time, the buttocks should not be covered with pillows, and the knees should be stood with the buttocks floating.

The muscular strengthening sites are sphincter muscles such as the perineum and anus,
Abdominal muscles, gluteus muscles, leg muscles, and psoas muscles. For each of the above positions, perform perineal exercises 10 times each with open and closed legs, for a total of 100 times. The stance for opening legs should be slightly wider than your shoulder width. If the above training is carried out once a day for 2 to 3 months, an outstanding effect will appear. If it is difficult to perform gymnastics with both hands on the back of the head, both hands may be placed on the body side or in front of the body.

In addition, it is possible to prevent a decrease in muscle strength only around the perineum,
As a simple method for strengthening muscle strength, perineal exercises can be performed in a sitting position as shown in FIG. When the training is completed, the fixing plate 70 is pulled to remove the perineal gymnastics from the vagina. Since the tampon 20 is a so-called disposable one, a new tampon 20 is replaced when it is used again.

As described above, according to the perineal gymnastics of this embodiment, the perineal muscle group contraction training can be easily performed only by inserting the main body into the vagina and tightening or loosening the anus. . Moreover, the magnet pieces 30 can enhance the sphincter function of the muscles particularly in the lower third of the vagina, and as a result, the pelvic floor muscles can be reasonably and effectively strengthened.
In particular, the bladder sphincter can be strengthened to effectively prevent and treat urinary incontinence. In addition, since it is possible to perform treatment personally without being known to others and to perform perineal exercises while wearing underwear, it is possible to perform training while performing other work.

Furthermore, since the perineal gymnastics is intended to strengthen the pelvic floor muscle group, in addition to the above effects, the following ripple effects can be obtained. It is said that the first cause of low back pain in adult women is the stagnation of blood flow in the pelvis. Therefore, by strengthening the pelvic floor muscle group, the stagnant blood flow in the pelvis can be improved, and the above-mentioned low back pain can be treated and prevented.

By strengthening the anal sphincter, prolapse of the anus can be prevented and fecal incontinence can be prevented. Strengthening of the abdominal wall muscles may prevent built-in drooping and postural flexion. Also, to promote peristalsis of the intestine,
It can improve chronic constipation. By strengthening the lumbar spine, it works to prevent anteversion of the posture and maintain a correct posture, which in turn can prevent and improve muscular back pain.

By strengthening the gluteus maximus, the slack in the gluteal muscles is corrected and the hip-up action is promoted. It also strengthens the muscles of the lower limbs, in the upper thighs it removes subcutaneous fat in the thighs to improve muscle slack, and in the lower thighs it can strengthen the calves to remove muscle slack around the ankles and subcutaneous fat It is a thing.

The present invention is not limited to the above embodiment, and the effect of perineal exercises can be obtained without the tampon 20. Similarly, the effect of the perineal gymnastics can be obtained without the fixing plate 70. Therefore, as the perineal gymnastics device, at least one or both of the tampon 20 and the fixing plate 70 may be omitted.

Further, the shape of the main body 10 is not limited to the pear shape, and in short, if the whole is constituted by a smooth curved surface, it may be a straight rod shape or may be slightly curved. The size and shape of 10 does not matter. further,
In the present embodiment, since the target is a Japanese adult woman, the total length L of the main body 10 is set to 70 mm, the diameter D1 of the base end portion 11 is set to 20 mm, and the maximum diameter D2 of the tip end portion 12 is set to 34 mm. However, in the case of Western or black adult women, it is anatomically preferable to enlarge the total length by 2 cm and the maximum diameter by 5 mm.

Further, the mounting method of the tampon 20 is shown in FIG.
As shown in FIG.
The female screw 25 may be formed on the inner surface of the base portion 21 of the above and may be attached by screwing. In addition, the mounting portion 50 is formed into a tubular shape,
It is also possible to form an internal thread on its inner surface and an internal thread on the base of the tampon 20. Further, the perineal gymnastics device may be configured as shown in FIG. That is, the main body 10 has a pear shape, and the size of each part is the same as that of the perineal gymnastics A of the above-described embodiment. Further, the base end portion 11 of the main body 10 is provided with a withdrawal line 40 made of a nylon or cotton thread. After the perineal exercise, the withdrawal line 40 is pulled to pull out the perineal exercise machine from the vagina. ing. By doing so, the portion exposed to the outside of the vagina is smaller than the case where the fixing plate 70 is provided, and the gymnastics with the underwear attached becomes easier. In addition, as shown in FIG.
0 may be exposed on the surface of the main body 10.

The size of each part does not necessarily have to be fixed to the size shown in the above embodiment, but is an average size determined based on the anatomical basis of a Japanese adult woman, It is the size that can obtain the most remarkable effect. Further, the number of magnet pieces 30 can be increased to four or more. In addition, various design changes can be made without changing the gist of the present invention.
