Magnetic stimulation device
Provided is a magnetic stimulation device, which does not feel hot to the user. The magnetic stimulation device ( 1 ) comprises: a contact plate ( 2 ) to be disposed near the user's head; an exciting coil ( 3 ) to be held above the contact plate ( 2 ); a casing ( 4 ), which covers at least the upper side of the exciting coil ( 3 ), in which openings ( 17, 18 ) are provided above the center of the exciting coil ( 3 ) winding, and in which a gap that is open on the outside of the exciting coil ( 3 ) is formed between the casing and the contact plate ( 2 ); and a suction fan ( 5 ) for drawing out air between the contact plate ( 2 ) and the casing ( 4 ) from the openings ( 17, 18 ) of the casing ( 4 ).
1. A transcranial magnetic stimulation device comprising:
a contact plate configured to be disposed near a head of a user;
an exciting coil held above the contact plate;
a casing disposed above the contact plate, the casing having upper and lower portions covering upper and lower portions of the exciting coil, respectively, and an opening extending through the upper and lower portions of the casing, the lower portion of the casing fully covering the lower portion of the exciting coil and defining a space between the lower portion of the casing and the contact plate, the space opening directly to an atmosphere outside the device and in direct communication with the opening; and
a fan, disposed above the opening, for directly drawing air from the atmosphere into the space and between the contact plate and the lower portion of the casing.
2. The transcranial magnetic stimulation device of claim 1 ,
wherein the exciting coil is formed by winding a conductor in a planar manner, and
wherein the opening is positioned above a winding center of the exciting coil.
3. The transcranial magnetic stimulation device of claim 1 , wherein the contact plate is a shell configured to be placed on the head of the user.
4. The transcranial magnetic stimulation device in claim 1 , wherein the contact plate has a same shape as a bottom surface of the lower portion of the casing and covers the bottom surface.
5. The transcranial magnetic stimulation device in claim 1 , wherein the fan cools the exciting coil with air introduced into the space and forms a dynamic heat-insulating layer of the air introduced in the space to prevent a temperature increase of the contact plate.
6. A transcranial magnetic stimulation device comprising:
a contact plate configured to be disposed near a head of a user;
an exciting coil held above the contact plate;
a casing disposed above the contact plate, the casing having upper and lower portions covering upper and lower portions of the exciting coil, respectively, and an opening extending through the upper and lower portions of the casing, the lower portion of the casing fully covering the entire lower surface of the exciting coil and defining a space between the lower portion of the casing and the contact plate, the space opening directly to an atmosphere outside the device and in communication with the opening; and
a fan, disposed above the opening, for directly drawing air from the atmosphere into the space and between the contact plate and the lower portion of the casing.
7. The transcranial magnetic stimulation device of claim 6 ,
wherein the exciting coil is formed by winding a conductor in a planar manner, and
wherein the opening is positioned above a winding center of the exciting coil.
8. The transcranial magnetic stimulation device of claim 6 , wherein the contact plate is a shell configured to be placed on the head of the user.
9. The transcranial magnetic stimulation device in claim 6 , wherein the contact plate has a same shape as a bottom surface of the lower portion of the casing and covers the bottom surface.
10. The transcranial magnetic stimulation device in claim 6 , wherein the fan cools the exciting coil with air introduced into the space and forms a dynamic heat-insulating layer of the air introduced in the space to prevent a temperature increase of the contact plate.
