Abstract

A flat coil or coils of conductive wire are connected to a low voltage direct current power pack, so as to produce magnetic flux in the order of 10 mu Wb to 10 mWb. The flat coil or coils are laid flat side against the human or animal body so as to drive magnetic flux through the body and heat that area of the body. The magnetic flux is to promote healing and the heat relieves pain.

Description

THERMO-MAGNETIC BODY COILS This invention relates to a thermo-magnetic body coil or coils and power pack, for the purposes of pain relief and to promote healing in living beings.
It has been known for at least 2000 years that heat frequently relieves pain and that magnetism can promote healing. There are separately available electrical heat pads and permanent magnets, but none have been combined into a convenient easily donned arrangement. Portable permanent magnets exhibit relatively low levels of magnetic flux and heat pads normally use full mains voltage.
According to the present invention there is provided a power pack which changes the mains supply alternating current into a safe low voltage direct current which supplies ä~lat wound electro-magnetic coil or coils.
'2he electro-magnetic coil or coils produce magnetic flux in the order of 10 'w1b to 10 m'Wb, with coil centre flux density in the order of 1 mT to 100 mT, and a coil windings temperature in the order of 4000 to 1000C is produced. The coil windings may be made from any conductor, but copper or aluminium are most efficient. Uhe coils may be circular, oval or rectangular to cover the affected area of the animal or hurnan body, the length or maximu:n invention of the coil or coils divided by their tilic'eness is in the order of 10 to 100. The coil or coils are arranged so as to drive magnetic flux through the body.
A specific embodiment of the invention will now be described by way of example:- A coil of outside diameter 148 mm, inside diameter of 64 mm and thickness of 7 mm is wound using 474 turns of insulated copper wire of 0.67 mm diameter, this coil is held in shape by several lengths of interwoven nylon cord and covered in PVC upholstery cloth for electrical insulation. The coil is connected to a power pack which provides two voltages, nominally 8 V and 12 V direct current. The coil is laid flat side against the affected area of tle human body and connected to tile 12 V supply, after approximately a quarter to half an hour the temperature of the coil has risen to a comfortable level at which time the power pack is switched over to 8 V, the coil is left in place for another half hour approximately then removed. Periods in excess of one hour may cause drowsiness. On the 12 V setting the coil produces 69 pit and a coil centre flux density of 8.9 mT, on the 8 V setting this reduces to 46 Wb and 5.9 mT, these values will vary slightly with coil temperature and mains voltage.

Claims (8)

1 A thermo-magnetic body coil comprising an electro-magnetic coil whose overall diameter is substantially larger than its thickness and is supplied with low voltage direct current from a power pack which is connected to mains alternating current.
2 A thermo-magnetic body coil as claimed in Claim 1, wherein a pair of electro-magnetic coils are placed on opposite sides of an animal or human body so as to drive magnetic flux through that body.
3 A thermo-magnetic body coil as claimed in Claim 1 or Claim 2 wherein several electro-magnetic coils are placed on an animal or human body.
4 A thermo-magnetic body coil as claimed in any preceding claim wherein the coil windings are insulated copper..
5 A thermo-magnetic body coil as claimed in Claim 1, 2 or 3 wherein the coil windings are insulated aluminum.
6 A thermo-magnetic body coil as claimed in any preceding claim wherein the low voltage is supplied by battery.
7 A thermo-magnetic coil as claimed in Claim 1, 2, 3, 4 or 5 wherein the electrical power is supplied by rectified mains alternating current.
8 A thermo-magnetic body coil as claimed in Claim 1, 2, 3, 4 or 5 wherein the electrical power is supplied by generator.
