Magnetic stimulation methods and devices for therapeutic treatments
Methods and devices producing time varying magnetic field have therapeutic uses. The device contains a coil made of insulated wires, an energy storage device, an energy source and a switch. The coil is flexibly attached in a case. The device has at least one blower for cooling the coil. The methods and devices can be used in for example in physiotherapy, neuropsychiatric therapy, aesthetic therapy, urology or urogynecology.
1. A magnetic stimulation device producing a time varying magnetic field for treatment, comprising:
a connection to an energy source, a switch, a coil, an energy storage device, at least one blower and a casing;
with the blower arranged on a circumference of the coil; and
wherein the coil and the casing are arranged in a manner that fluid can flow in-between them and wherein the coil is cooled by fluid flow over at least upper and lower sides of the coil.
2. The device of claim 1 wherein the fluid is air.
3. The device of claim 2 wherein the coil is a flat type coil.
4. The device of claim 2 wherein the coil comprises insulated wires.
5. The device of claim 2 wherein the coil is attached to the casing by at least one fastening point.
6. The device of claim 5 wherein the at least one fastening point is located on an outer circumferential side of the coil to enable fluid flow over at least the upper side and the lower side of the coil.
7. The device of claim 6 wherein the at least one fastening point is flexible.
8. The device of claim 6 comprising a plurality of fastening points and wherein at least one of the fastening points is rigid.
9. The device of claim 5 wherein the at least one fastening point is rigid.
10. The device of claim 1 wherein a spacing for fluid flow of at least 0.1 mm is provided between the upper and/or the lower side of the coil and the casing.
11. The device of claim 1 further including an outlet on an upper side of the casing.
12. A magnetic stimulation device producing a time varying magnetic field, comprising:
an energy source electrically connected to a switch, a flat coil, and an energy storage device;
at least one blower in a casing, with the blower on one side of the coil and positioned to blow air across upper and lower sides of the flat coil, in a direction parallel to the upper and lower sides of the flat coil; and
with at least one of the upper and lower sides of the flat coil spaced apart from the casing to allow air to flow between them, to cool the coil.
