Abstract

PROBLEM TO BE SOLVED: To provide a non-invasive device not accompanied by unpleasant feelings, pains and the sense of shame regardless of ages or sexes by providing a coil installation tool installed inside a room and a coil power feeding means for feeding power to a magnetic stimulation coil so as to generate pulse-like magnetic fluxes, repeatedly. SOLUTION: When a patient sits on the coil assembly 19 of a sitting part 1a the magnetic flux is generated from an anus peripheral part to an upper part. At this time, by resistance loss, the entire magnetic stimulation coil becomes a heating element, however, by circulating cooling water from a cold water device 3, low temperature burns and high temperature burns by large power are prevented and a strong treatment is performed. Then, since the magnetic flux intrudes deep inside a body and an eddy current is generated even in a deep part, not only a pelvis bottom muscle group but also external urethra sphincter muscles directly surrounding a urethra and a genital area nerve which is a branch generated from second-forth sacral nerves are effectively stimulated. Thus, while wearing clothes, the treatment is performed just by sitting on a chair 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a urinary incontinence treatment method and device for performing magnetic treatment by generating an eddy current in a living body by a magnetic stimulation coil which is supplied with a pulse current and generates a magnetic flux.

[0002]

2. Description of the Related Art Urinary incontinence, in which urine leaks against your will, has been neglected because it is not directly related to life, but it often impairs daily life, and countermeasures for it have been demanded. In particular, in recent years, the number of patients with urinary incontinence tends to increase with the rapid progress of aging. In addition, the number of urinary incontinence patients, regardless of children or men and women, and the number of patients with spinal cord injury due to traffic accidents are increasing, and a good treatment method for improving the lives of these patients is desired.

On the other hand, as a treatment method for urinary incontinence, in addition to a method using a drug or surgery, an electric electrode for attaching a stimulating electrode to a living body and applying an electric pulse to treat stress urinary incontinence, urge incontinence, etc. Stimulation therapy is well known. The stimulation points are located in the lumbosacral plexus that controls the lower urinary tract, the pelvic floor muscle group, and the external urethral sphincter, but they are stimulated in the anus or vagina to facilitate stimulation from the body surface. ing. In this case, an intravaginal plug-type electrode with a diameter of 2 cm and a length of about 4 cm connected to the pulse wave generator or an intraoral electrode with an hourglass shape of similar size is inserted into the vagina or anus, and then several Hz to Repetition frequency of several + Hz, peak current of about 1 to 100 mA and 5
A pulse current having a pulse width of about 0 μs to 5 ms is directly applied from the body surface. At that time, the repetition frequency is several Hz for urinary incontinence, and several + H for the treatment of stress urinary incontinence.
Normally set to z. The treatment is generally performed by applying electrical stimulation for about 15 minutes once a day and repeatedly for 2 to 4 weeks.

As a result, the pelvic floor muscle group is stimulated and trained from the body surface with a pulse current, the weakened muscle group is strengthened, and the force for tightening the urethra becomes stronger, which is effective for the treatment of stress incontinence. For urinary incontinence caused by involuntary bladder contraction, urinary incontinence is suppressed by reflexively suppressing involuntary bladder contraction by stimulating the pudendal nerve or its branches originating from the 2nd to 4th sacral nerves. Can be prevented. It is also well known to attach a skin surface electrode to the vulva or its surroundings to electrically stimulate the pudendal nerve in the same manner.The effect can be sustained even after the stimulation treatment is stopped by repeating stimulation. It is also known to be effective. Further, it is known to be effective in treating bladder pain, frequent urination and nocturia.

[0005]

However, in such an electrical stimulation method using a plug-shaped electrode, the electrode must be inserted into the vagina or anus every time, which causes discomfort and shame to the patient. In addition, demanding such an operation from a child, an unmarried woman, or an old man causes an unreasonable action itself, and causes problems such as refusal of treatment and refusal to continue treatment. Furthermore, if the stimulation current is increased in order to obtain the effect quickly and in a short period of time, there is a risk of causing pain or even burns. For this reason, the stimulus intensity is gradually increased to a level at which no discomfort is felt or a limit that can be tolerated is set, but the intensity of the stimulus varies greatly depending on the shape of the electrode and the individual, and the sensory disturbance Burns can occur in some patients, leaving problems. In addition, since the electrodes are repeatedly inserted and used in the vagina and anus, there are problems such as inflammation and infection, and it can be said that this is a non-invasive but near-invasive act.

To alleviate this problem, a method of non-invasively adhering a skin surface electrode to the skin around the vulva is also used, but similarly, pain and burns are more likely to occur due to an increase in current, Also, repeated sticking every day makes it easier to get a rash. Its use in patients with desensitization is also problematic.

In view of the above problems, it is an object of the present invention to provide a device for treating urinary incontinence which is non-invasive, does not cause discomfort, pain or shame, and is of any age or sex. To do.

[0008]

The present invention focuses on the fact that an eddy current can be generated by supplying a pulsed magnetic field without directly applying a pulsed current to a living body, and is effective for treating urinary incontinence. It is based on the development of a magnetic stimulation method for generating pulsed magnetic flux from an external position that allows the pulsed magnetic flux to enter the muscle group, the external urethral sphincter, or the lumbosacral nerve system.

According to Japanese Unexamined Patent Publication No. 57-22770, the current supply to the magnetic stimulation coil is controlled by switching the charging voltage of a capacitor charged by a DC power source through a switching element that is switching-controlled at a predetermined repetition frequency. A magnetic therapy device adapted to discharge a stimulation coil is disclosed. According to this magnetic therapy device, the pulsed magnetic flux having a frequency other than the commercial power supply can be generated in the power supply circuit having a small internal resistance, and the pulse stimulation mode can be easily changed. However, the magnetic stimulation coil is intended to treat stiff shoulders, muscle fatigue, rheumatoid arthritis, etc. by attaching it to the body with a suction cup or the like to improve blood flow, and a treatment for urinary incontinence is disclosed. It has not been.

In order to achieve this object, the urinary incontinence treatment apparatus of the present invention comprises, according to claim 1, a magnetic stimulation coil which is set at a site within the range from the waist to the lower limbs of a patient to generate a magnetic flux. And a coil deferment tool that is deferred in the room,
The magnetic stimulating coil is provided with a coil power supply means for supplying power so as to repeatedly generate a magnetic flux having a pulse shape.

Such a coil fixture is placed in a hospital or home, and the magnetic stimulation coil is placed within a range from the waist to the lower limbs, that is, the vulva or its periphery, the anus or its periphery, the lower abdomen, the buttocks or the waist. When it is set to, the magnetic flux penetrates into the body, and the pudendal nerves that occur from the lumbosacral nerve system, the second to fourth sacral nerves, which are difficult to electrically stimulate from the pelvic floor muscles and the body surface, The external urethral sphincter is easily stimulated by eddy currents. Nerves originating from the 2nd to 4th sacral nerves are distributed in the lower limbs and can be effectively stimulated. Particularly, by generating a pulsed magnetic flux of 1 to 100 Hz having a magnetic flux density of 0.01 to 3 Tesla, a good therapeutic effect on urinary incontinence can be obtained.

In the conventional electrical stimulation method, a current concentrates on a portion in contact with a plug-type electrode or a skin surface electrode and a body surface to cause a loss, and only a small current flows to a portion to be stimulated for the magnitude of an applied voltage. Since the stimulation efficiency is not good because there is no eddy current, the present invention has no current loss on the skin surface and can easily generate an eddy current to a deep portion effective for treatment. Further, in the present invention, since the magnetic flux generating surface is widened and reaches a deep portion, the eddy current generating region can be widened, and even if the current is increased, it is less likely to cause pain.

In order to enable treatment in daily life, according to the present invention, a magnetic stimulation coil for generating a magnetic flux toward the vulva of the patient or its periphery and a magnetic stimulation using a battery as a power source are provided. A portable urinary incontinence treatment device is provided by providing coil power supply means for supplying power to the coil so as to repeatedly generate pulsed magnetic flux. Claim 1
According to 3, the body wearing tool is composed of a band worn on the lower end of the thigh and a pochette worn on the waist, and a magnetic stimulation coil for generating magnetic flux toward the back of the knee is attached to the band. In the pochette, the coil power feeding means that feeds the magnetic stimulation coil so as to repeatedly generate the pulsed magnetic flux is housed in the pochette, so that the region within the range from the waist to the lower limbs, that is, the pudendal innervation region is added. ,
The sciatic nerve and tibial nerve, which are the lumbosacral nerve system, can be stimulated, which is effective for the treatment of urge incontinence.

When performing continuous stimulation for 10 to 15 minutes with a magnetic flux density of more than about 0.07 Tesla, in order to avoid low-temperature or high-temperature burns due to the temperature rise of the stimulation coil, effective treatment is possible. Preferably, the cooling means cools the magnetic stimulation coil.

[0015]

1 to 3 illustrate a stationary urinary incontinence treatment apparatus according to an embodiment of the present invention. This coil fixture uses the chair 1, and the coil assembly 19 shown in FIG. 2A is placed on the seating portion 1a thereof. At the center of a disc-shaped container 10 made of synthetic resin of this assembly, a one-turn magnetic stimulation coil 1 made of a hollow conductor is provided.
A plurality of mold coils 12 arranged in a circular shape and molded with a synthetic resin are arranged. Both ends of each magnetic stimulation coil 11 are sequentially connected by an insulating water supply pipe 13, and one end thereof is connected to a water supply pipe 4a of a pump 4 so as to circulate cold water supplied from the cold water device 3. The other end is connected to the drain pipe 4b. Further, each magnetic stimulation coil 11 is connected in parallel and is connected to the output terminal of the power feeding device 5 that houses the coil power feeding means by the conductive wires 5a and 5b.

FIG. 3 shows the circuit configuration of this coil power supply means. The DC power supply 15 is capable of adjusting the voltage in the range of 100V to 3kV, the capacitor C1 of about 300 .mu.F charged by this DC power supply, and its charging voltage. 16 applied to the magnetic stimulation coil 11 through the protection resistor R1 and a thyristor 16a absorbing a reverse voltage when the switch is turned off.
And a switching control circuit 17 for performing on control, that is, firing control of these thyristors through a transformer 16b. This switching control circuit is 1Hz
The repetition frequency can be adjusted in the range of 100 Hz to 100 Hz. Winding structure of magnetic stimulation coil 11, DC power supply 15
The pulse width is 10 depending on the voltage of
All the current pulses of the magnetic stimulation coil 11 are configured to generate a magnetic flux having a magnetic flux density of about 3 tesla at a maximum value of about 3000 A at a peak value of about 0.01 tesla at about 0 μs.

The patient has a coil assembly 19 on the seat 1a.
By sitting on the floor, magnetic flux is generated upward from around the anus, and at that time, the magnetic stimulating coil 11 becomes a heating element of about 1 to 70 W due to resistance loss, but when it exceeds about 5 W, cooling water is circulated. Prevents low-temperature burns or high-temperature burns with higher power. Therefore, powerful treatment for about 15 minutes can be continuously performed. The conventional electrical stimulation method is the inferior rectal nerve distributed in the skin near the skin surface, the outer skin around the anus and the external anal sphincter, or the perineal nerve distributed in the perineal skin and muscle, and the dorsal penile nerve distributed in the penis,
While mainly stimulating the clitoral dorsal nerves distributed in the clitoris, magnetic flux penetrates deep inside the body and eddy currents are generated even in deep areas. It effectively stimulates the external urethral sphincter that directly surrounds the pudendal nerve and the urethra, which are branches that originate from the sacral nerve. The repetition frequency is set to several Hz for urge incontinence, and several + Hz is set for treatment of stress urinary incontinence. You can treat it by sitting on chair 1 with your clothes on.

The switching control circuit 17 is not limited to a single pulse, but a double pulse of about 100 μs (upper stage of FIG. 4) or a continuous pulse (FIG. 4) is used so that the pulse width is not widened to cause pain. (Lower part of 4) is also considered. Furthermore, if you accept the complicated configuration of the power supply circuit, prepare both positive and negative DC power supplies,
By generating the bipolar pulse (middle stage in FIG. 4), it is possible to effectively generate the eddy current by increasing the magnetic flux change without increasing the power supply voltage. In addition, multiple consecutive pulses depending on the condition of the patient's stimulation site and symptoms,
Various pulse stimulation modes such as bipolar double pulse can be used. The pulse width is not limited to 100 μs, but is set to about 50 μs to 5 ms depending on the state and symptoms of the stimulation site.

The pulse width can be varied by selecting a plurality of capacitors connected in parallel and varying the capacitance, or by switching the inductance of the coil. For electrophysiology, increasing one of the current and pulse width
On the other hand, there is a relationship called chronaxie (chronic value) that can be effectively stimulated even if it is small. That is, the pulse width can be adjusted by increasing the charging voltage when increasing the pulse width and decreasing it when decreasing the pulse width.
Also, by setting the current and pulse width appropriately,
Effective stimulation can be performed with minimum power consumption.

FIG. 2B shows another structure of the coil assembly 19. Each of the two turns of the magnetic stimulating coil 11a, which is insulated and wound, is independently connected to each of the water supply pipe 4c and the drain pipe 4d, and each of the lead wires 5c. Power is supplied at 5d. Therefore, N of the magnetic field of each magnetic stimulation coil 11a
It is possible to change the distribution of the magnetic flux density or increase the magnetic flux to the stimulation site by setting the pole and the S pole independently and setting the polarity arbitrarily.

FIG. 5A shows a coil holder using the bed 20, and as shown in FIG. 5B, a synthetic resin mold coil group 22 in which a plurality of magnetic stimulation coils 21 are embedded in a ring shape is provided on the buttocks of the mat 23. It is embedded in the bed part opposite to. In this case, magnetic flux is generated from the lower part of the buttocks, so that it is possible to easily stimulate the pudendal nerves such as the perineal nerve, the dorsal penile nerve, the clitoral dorsal nerve, and the pelvic floor muscle group, and the external urethral sphincter muscle. For example, a long-term treatment of about 15 minutes can be performed while sleeping. At this time, by arranging the magnetic body 25 such as ferrite in the abdomen, the magnetic flux diverging to the periphery can be concentrated in a region having a high therapeutic effect, and efficient stimulation can be performed even with the same applied voltage. Similarly, it is effective in treating urgency and stress incontinence.

FIG. 5C shows a modification of the bed-type coil fixture. On the bed body, a case 27 made of transparent synthetic resin is placed as a supine part instead of the mat 23. A slider 26 having a mold coil group 22 mounted therein and having a handle 29 for performing a sliding operation from the outside, and a rail 28 for slidably guiding the slider at least between positions corresponding to the knees to the waist.
And are stored. This rail can be extended further to the toes.

FIG. 6 shows a coil fixture using a stand, which is rotatable about 90 ° between a stand 30 installed near the bed 20 and a position which escapes above and to the side of the bed 20. The coil supporting arm 31 is supported by a support shaft portion 32 supported by a rotating arm 33 of 30 and has a magnetic stimulation coil embedded therein. After the patient lays on the bed 20, the coil support arm 31 is rotated from the escape position to the upper part of the abdomen, and a current pulse is similarly supplied by the attached coil power supply means to perform magnetic stimulation. Rotating arm 3
Further rotation can be performed by rotating 3. In this case, magnetic flux is generated from the lower abdomen or below the bed while lying in a normal bed, and urgency and stress urinary incontinence can be treated.

FIG. 7A shows a coil holder which allows a patient to be treated while standing up. A stand 40 and a plurality of magnetic stimulation coils 46 are arranged in a circular shape so as to form a ring surrounding the patient in a closed state. In addition, the pair of half-ring-shaped coil support arms 45 and 45a (FIG. 7B) whose bases are rotatably supported by the support shaft portion 42, and the support shaft portion 42 at the tip end portion, and the ascending / descending position are It is provided with a support arm 41 which is guided by a guide rod 47 so as to be able to move up and down so as to be locked by a lock screw 47a. During magnetic stimulation for the treatment of urgency and stress urinary incontinence, the coil support arm 45,
45a is opened and the patient is closed with the patient standing therein. In this case, the magnetic stimulation coil 46 is set on the entire circumference of the lower abdomen, and magnetic flux is generated from the surroundings toward the inside. Further, by making a plurality of magnetic stimulating coils 46 selectable, it is possible to appropriately select a stimulating site, and further, to achieve efficient stimulus that saves power consumption under the minimum stimulus intensity felt by the patient. Become. The magnetic stimulation coil 46 is shown in FIG. 7C.
As shown in FIG.
It is also possible to wind on each of 5a over a semicircular region.

The magnetic stimulation coil support arms 45, 45
As shown in FIG. 7D, a plurality of magnetic stimulation coils 46a wound in a vertical plane may be arranged in a. In this case, by causing currents to flow in opposite directions to the adjacent magnetic stimulation coils 46a, magnetic flux diverging to the periphery can be concentrated and added to the adjacent coils, and eddy currents can be made to flow concentratedly between the adjacent coils. it can. This method is effective for reducing the applied voltage or the power consumption, especially when there is a stimulation site on the surface of the living body. By selecting adjacent coils, it is possible to select a site with good stimulation efficiency. Further, by causing currents to flow in opposite directions to the magnetic stimulation coils 46a at the opposite positions via the living body in the magnetic stimulation coil support arms 45 and 45a on both sides, one magnetic flux is attracted to the other magnetic flux, and the applied voltage or consumption is reduced. The electric power can be reduced to stimulate deep inside the living body. Further, it may be considered that one or a plurality of magnetic stimulation coils 46a have a mounting structure that can be replaced with a magnetic material having a high magnetic permeability.

8A and 8B show a U-shaped coil support arm 53 provided on a stand 50, and two magnetic stimulation coils 5 wound in a vertical plane on the front and rear arm portions.
1, 51a are provided so as to be located in front of and behind the living body. By supplying power to both of these magnetic stimulation coils in the same direction and at the same timing, the polarities of the magnetic flux become opposite to each other on both sides of the living body, so that the magnetic field lines of one coil are directed to the other coil and the magnetic flux diverging to the surroundings. Concentrate on the line connecting the centers of the magnetic stimulation coils 51, 51a. As a result, even if the eddy current of only one coil does not reach the threshold effective for treatment, the threshold is exceeded by the total eddy current with the other coil, and therefore the applied voltage or power consumption is reduced to stimulate deep inside the living body. it can. By providing the magnetic stimulation coils 51 and 51a so that they can be displaced, the site to be efficiently stimulated can be changed during treatment. Also, three or more magnetic stimulation coils may be provided.

Further, as a modification of this embodiment, by placing a metal having a high magnetic permeability in place of either one of the magnetic stimulation coils 51 or 51a, the magnetic flux is directed to this metal, and therefore the magnetic flux is magnetically stimulated. It is possible to concentrate on the line connecting the coil 51 or 51a and the center of the metal having good magnetic permeability, reduce the applied voltage or power consumption, and stimulate deep inside the living body. By displacing this kind of metal from the position directly facing the magnetic stimulation coil, the stimulation site can be changed efficiently. Also, by disposing this metal displaceably, it can be changed even during treatment.

In order to prevent low-temperature burns, the coil fixture described with reference to FIGS. 5 to 8 can also be provided with cooling means in the same manner. As the cooling means, distilled water or particularly tap water for home use can be used, and a refrigerator for performing a refrigeration cycle operation can be used instead of the cold water circulation type described above.

In the air-core coil, the magnetic flux density is the largest on the central axis and gradually decreases toward the outside. Further, the eddy current is generated in proportion to the portion having a larger magnetic flux in proportion to the time derivative of the magnetic flux. Therefore, in the above-described FIG. 8 or other embodiments, particularly in the case of treatment of urge incontinence in which stimulation of several Hz is performed, even if a magnetic core such as an iron core or ferrite is adopted, the heat generation due to the loss does not occur. Since the magnetic core does not become large, it is possible to prevent the magnetic flux from spreading outward by embedding the magnetic core in the air-core portion of the magnetic stimulation coil and concentrating the magnetic flux on the axis. For example, it is possible to set the tip of the magnetic core to a region with a low threshold value in the pudendal nerve and concentrate the magnetic field to efficiently stimulate the magnetic field. In each of the above-described embodiments, the magnetic stimulation coil may be one large circular coil instead of arranging a plurality of coils.

FIG. 9 shows a portable urinary incontinence treatment device. In this device, a belt 60, which is worn on the waist as a body attachment to the human body, is provided with a pochette 63 for accommodating the coil power supply means having the same configuration as in FIG. A local cup 61 having a magnetic stimulation coil storage case 62 made of cloth or soft resin attached to a position facing the vulva is provided below. In this case, the battery voltage is set to about 20V, and the magnetic stimulation coil is configured to generate a magnetic flux of about 0.01 to 0.1 Tesla by passing a maximum current of about 10A.

By attaching the belt 60 to the waist, magnetic fluxes from the magnetic stimulation coil toward the vulva are magnetically stimulated to the pudendal nerve or its branch for the treatment of urge incontinence. Also,
When the frequency is set to several tens Hz, the pelvic floor muscles and the external urethral sphincter contract, which is effective in treating stress urinary incontinence. It is easy to put on and take off, it puts less strain on daily activities, and there is no discomfort. Therefore, the treatment can be continued without being rejected, so that the therapeutic effect can be enhanced at an early stage. Since the magnetic stimulating coil generates heat of about 1 to 10 W, a feeling of strangeness due to heat is generated by embedding a cooling element, such as a Peltier element, which is supplied with current from the battery and exhibits an endothermic effect in the air-core portion 62a of the magnetic stimulating coil. It can be lost. Instead of such a cooling element, an air-cooled type using a fan can be used. As a portable type, it is possible to further increase the magnetic flux density up to about 1 tesla.
In addition, instead of the local cup 61, in order to attach a magnetic stimulation coil to a male penis, a ring-shaped penis attachment device made of an elastic material into which the penis is inserted, or a band-shaped penis attachment wound around the penis and fastened with a hook-and-loop fastener. The device may be a body wearing device together with the belt 60.

FIG. 10 shows a portable urinary incontinence treatment device when the body-worn device is pants. A case 72 for accommodating the magnetic stimulation coil is attached to the front part of the pants 70, and a battery type magnetic stimulation coil power supply means is accommodated in a pochette 73 provided on the upper part of the pants 70. Also in this case, since the magnetic stimulation coil is located in the lower abdomen, it can be easily attached and detached and the daily activities are less burdened.

FIG. 11 shows a portable urinary incontinence treatment device for stimulating the tibial nerve of the back of the knee, which is relatively close to the body surface, similarly to the case where the dorsal nerve of the penis is distributed on the dorsal side of the penis and the foreskin. . In this case, a case 82 for accommodating the magnetic stimulation coil wound along the back of the knee is attached as the body attachment, and the adhesive band 80 attached to the lower end portion of the thigh 81 and the magnetic stimulation coil are attached. A pochette with a locking piece 84, which houses the coil power feeding means from which the lead wire 83 for feeding power is drawn and which is mounted on the waist, is provided. The magnetic stimulation coil
A litz wire with a diameter of about 0.5 mm is wound and covered with a soft insulating synthetic resin skin. As a result, it has been confirmed that the magnetic stimulation coil is flexibly attached to the back of the knee according to the curved surface thereof, and the stimulation for the urinary incontinence treatment which is urged mainly is effectively performed with the minimum power consumption. . At this time, an adhesive gel conductor may be attached to the left and right sides of the knee so that the eddy current can easily flow to the living body. Further, if a hole is formed in the central portion of the magnetic stimulation coil housed in the case 82, it can be easily attached to a site having a large stimulation effect by using the hole as a mark.

[0034]
