Description

HOME TRANSCRANIAL MAGNETIC STIMULATION MEDICAL DEVICE [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a home medical instrument, and more particularly, to a miniature magnetic transducer for home use.

Transcranial magnetic stimulation (TMS) is a method of influencing the brain using strong magnetic force without surgical treatment of the head. It was discovered by Professor Anthony Baker of England in 1976 that the rate of information transmission of neurons increases when the magnetic force of the brain is about 2T (1T = 1Wb / m2, Wb is the unit of magnetic flux). Meanwhile, TMS has been approved by the US Food and Drug Administration (FDA) in 2008 as an effective treatment for depression.

The principle of TMS is to intercept a very powerful electrical current in the electromagnetic coil to produce a magnetic field of about 2 Tesla intensity through the coil. It is a method to stimulate the brain by inducing depolarization to the nerve cell of 1.5 ~ 2cm below the coil by transmitting the fluctuating energy of the magnetic field wave to the brain via two coils in a proper position.

A magnetic field is a space in which a magnetic force acts around a magnet, a current, or a changing electric field, and is also referred to as a magnetic field or a magnetic field. Currently, TMS devices used for medical use mainly use coils to form a magnetic field.

TMS has been actively studied for the treatment of depression, obsessive compulsive disorder, movement disorders, schizophrenia, dementia and brain dysfunction which are not responding well to medication and psychotherapy.

Korean Patent Publication No. 10-2011-0123831 discloses a pseudo magnetic stimulator for verifying the effectiveness of magnetic stimulation therapy.

On the other hand, TMS may sound inconvenient every time stimulation is given, but no specific side effect has been found. In addition, it is known that repeated TMS (rTMS), which repeatedly performs TMS, is effective in the treatment of depression.

Accordingly, there may be a demand for a miniaturized TMS medical device which can be easily used at home.

The present invention has been devised to cope with the above-described background art, and is intended to form a time-varying magnetic field used in a TMS medical device by using permanent magnets rather than coils.

The present invention has been devised to cope with the background art described above, and it is intended to provide a miniaturized TMS medical apparatus for use in the home.

The home medical TMS includes a main body and a fixed portion, the main body comprising: A magnetic field forming part for forming a magnetic field with at least one permanent magnet; A time-varying magnetic field generator for converting the magnetic field into a time-varying magnetic field; And a control unit for controlling operations of the time-varying magnetic field generating unit, wherein the fixing unit comprises: The main body can be mounted on the head portion of the user.

According to the present invention, the time-varying magnetic field used in a TMS medical device can be formed using permanent magnets other than coils.

According to the present invention, it is possible to provide a miniaturized TMS medical device for use in a home.

The main body 200 includes a magnetic field forming unit 400, a time-varying magnetic field generating unit 500, a control unit 600, an input unit 700, a display unit 800, a battery unit 900, a network unit 1000, (1100).

The time-varying magnetic field generating unit 500 includes a driving unit 510 for adjusting the magnetic field forming unit 400 to a predetermined distance from the user's head and a magnetic field blocking unit 400 for blocking the magnetic field formed in the magnetic field forming unit 400. [ (520). That is, the time-varying magnetic field used in the home-use TMS medical instrument 100 according to an embodiment of the present invention is formed by using permanent magnets other than coils. For this purpose, the driving unit 510 or the magnetic- 200). This will be described later.

The components shown in FIG. 2 are not essential, so that some components may be omitted or another component may be added to configure a home TMS medical device 100. Hereinafter, each component will be described in detail.

The body 200 includes the components and may form the contour of a home TMS medical device 100. The main body 200 may be made of various materials such as plastic, fabric, etc., and the components may be fixed to the main body so as to be protected from external and / or internal impacts and vibrations.

For example, in FIG. 5, the main body 200 is positioned at the head portion of the upper side of the user's forehead, but the present invention is not limited thereto. That is, according to one embodiment of the present invention, the main body 200 may be positioned on the head of a head as if wearing a headband. 1, the body 200 according to an embodiment of the present invention may be located in any area of the user's forehead.

Meanwhile, the fixing unit 300 according to an embodiment of the present invention may be configured as a hair band having elasticity by including a rubber band. The fixing part 300 may be formed of various materials such as fabric, leather, PVC, and urethane. As means for adjusting the length, various means such as a buckle, a Velcro, a snap button and the like can be included.

The magnetic field forming unit 400 according to an embodiment of the present invention includes at least one permanent magnet and may form a magnetic field. A process of forming a magnetic field using a permanent magnet according to an embodiment of the present invention will be described as follows. First, we examine the magnetic fields formed by TMS medical devices.

In a conventional TMS medical device, a magnetic field is formed by varying the intensity and direction of a current applied to a coil. On the other hand, a magnetic field can be formed using a permanent magnet. The magnetic field is a vector quantity. When a permanent magnet is moved, a magnetic field can be formed by a moving direction, a speed, and the like.

On the other hand, the intensity of the magnetic field can be expressed by the density of the magnetic force lines. In the case of magnets, the density of magnetic lines of force is high in both magnetic poles of the magnet, and the density of magnetic lines of force is low when the magnetic poles gradually move away from the magnetic poles.

The correlation between the magnetic field, the magnetic field line (magnetic flux) and the unit area is as follows.

,

,

The unit of magnetic field B is T (tesla, Tesla). The magnetic flux is denoted by Φ (pi) and its unit is webber (Wb).

On the other hand, the magnetic field can be formed by current or stimulation, whereas conventional TMS medical devices mainly use magnetic fields due to current.

According to an embodiment of the present invention, when a magnetic field is formed by using a permanent magnet, a method of determining the intensity of a magnetic field by a magnetic pole is as follows.

이다. Assuming that there is a magnetic monopole at a point in space and that the stimulus symmetrical with this is infinitely far away, the surrounding magnetic field becomes point-symmetrical with respect to the stimulus. The magnetic field strength H at the point where the magnetic charge of the stimulus is m and the distance r from the stimulus is equal to the intensity of the electric field at the charge q

to be.

Unlike electricity, however, there is no magnetic pole. The two poles always form a magnetic dipole. Therefore, the magnetic moment of the magnetic dipole should be taken into account when actually measuring the magnetic field strength.

When the magnetic dipole having the magnetic moment M at the origin O lies in the x-axis direction, the intensity of the magnetic field at a point P on the plane including the magnetic axis is

가 된다.

.

이 되고, 자축의 수직이등분선(y축) 상에 있는 점(θ=90°)의 자기장의 세기는

이 된다.Where r is the distance OP from the magnetic dipole and θ is the angle between the axis (x-axis) and OP. Therefore, the intensity of the magnetic field at the point (θ = 0) on the extension line of the magnetic axis (x axis)

, And the intensity of the magnetic field at the point (θ = 90 °) on the perpendicular bisector (y-axis) of the magnetic axis is

.

As described in the Background of the Invention, as described above, a magnetic field of about 2T must be formed for TMS treatment, and the magnetic field is more influenced by the distance r from the magnetic dipole than the magnetic moment. That is, since the intensity of the magnetic field is inversely proportional to the third power of the distance from the magnetic dipole, even when the position of the permanent magnet is minutely changed, the intensity change of the magnetic field can be large.

The home TMS medical instrument 100 according to an embodiment of the present invention may include a driving unit 510 and / or a magnetic shielding unit 520 to generate a time-varying magnetic field.

Time varying magnetic field is a magnetic field that changes abruptly in a short time around an electrical conductor such as a metal. Applying such a time-varying magnetic field generates an induced current in the conductor. The electrical conductivity of the human body is much lower than that of high-quality conductors such as metal, but it has the property of being a conductor. When a strong time-varying magnetic field is applied to the human body, induction currents can be generated to stimulate muscles or nerve cells.

The driving unit 510 according to the embodiment of the present invention may have the rotation axis in a direction parallel to the tangent of the portion where the magnetic field forming unit 400 contacts the head portion of the user and may rotate the at least one permanent magnet eccentrically .

As described above, the magnetic field is more influenced by the distance r from the magnetic dipole than the magnetic moment. That is, since the intensity of the magnetic field is inversely proportional to the third power of the distance from the magnetic dipole, even when the position of the permanent magnet is minutely changed, the intensity change of the magnetic field can be large.

The driving unit 510 according to an embodiment of the present invention can adjust the distance of the magnetic field forming unit 400 from the head of the user. For example, the driving unit 510 can adjust the magnetic field forming unit 400 to a predetermined distance from the user's head. The driving unit 510 can move a permanent magnet using a motor and form a magnetic field.

More specifically, the driving unit 510 has a rotation axis in a direction parallel to a tangent of a portion where the magnetic field forming unit 400 contacts the head portion of the user, and can rotate the at least one permanent magnet.

Alternatively, the driving unit 510 may linearly move the at least one permanent magnet in a direction parallel or perpendicular to a tangent of a portion of the magnetic field forming unit 400 contacting the head of the user.

That is, the magnitude and direction of the magnetic field are changed by the driving unit 510, so that a time-varying magnetic field can be generated. In other words, the intensity of the magnetic field may be changed through the driving unit 510, which forms the magnetic field in the magnetic field forming unit 400 and is controlled by the control unit 600. 4A to 4B will be described later in detail. The operation of the driving unit 510 may be controlled by a control unit 600, which will be described later, and may include one or more motors.

That is, the magnetic field affecting the user may have various intensities and directions depending on the speed and direction of the driving unit 510.

In addition, the magnetic field shielding part 520 may be formed to form a time-varying magnetic field. The magnetic field cut-off unit 520 according to an embodiment of the present invention can block the magnetic field formed in the magnetic field forming unit 400. For example, the magnetic field shielding part 520 is closed in such a manner that the magnetic field formed in the magnetic field forming part 400 is located in the direction in which the magnetic field is propagated to the user, thereby being closed so that the magnetic field is not propagated to the user, A time-varying magnetic field can be formed by being opened to propagate. The commands for controlling the overall operation of the magnetic shielding unit 520 such as the opening and closing cycle of the magnetic shielding unit 520 may be stored in the memory unit 1100 and controlled by the controller 600. [

That is, as described above, the magnetic field forming unit 400 may continue to form a magnetic field, and a function may be required to partially or temporarily block the magnetic field applied to the user by the magnetic-field intercepting unit 520. As a method of cutting off the magnetic field, there may be a method of surrounding a silicon steel plate (a core used for a transformer or the like) around the magnetic force, or creating a magnetic force opposite to the magnetic field to cancel each other. According to another embodiment of the present invention, a magnetic field affecting the user can be partially or temporarily blocked by using a magnetic shielding material such as a silicon steel plate.

When the driving unit 510 eccentrically rotates the permanent magnets constituting the magnetic field forming unit 400, a magnetic field is formed. In addition, the magnetic field interrupter 520 may have various shapes to block the magnetic field.

Alternatively, or alternatively, the home TMS medical device 100 according to an embodiment of the present invention may also stop / initiate the formation of the magnetic field by stopping and / or starting the operation of the magnetic field generator 400 have.
