Abstract
A magnetic field generator for therapeutic applications develops a static or direct current (DC) magnetic field. The generator is self-contained, and also concentrates the magnetic lines of flux in a specific area. A recipient of the therapy may thus place a limb, typically a wrist or lower portion of an arm, in the area of concentrated magnetic flux of the static magnetic field.
Claims16
A magnetic field generator for therapeutic application of a static magnetic field to a recipient, comprising:
- a magnetic field generating coil composed of a wound wire coil generating the static magnetic field in response to electrical power;
- a mounting member having the coil mounted thereon and having an opening therethrough of a size to permit insertion of a limb of the recipient in order to receive electromagnetic therapy from the magnetic field coil;
- an electrical power supply furnishing power to the magnetic field coil to cause the coil to generate a static electromagnetic field within the opening of the mounting member for application to the recipient's limb;
- a level control mechanism providing a reference signal representing a specified electro-magnetic field strength set point for regulating the power furnished to the magnetic field coil;
- a field strength sensor detecting the static electromagnetic field strength generated by the magnetic field coil and forming a field strength signal representing the detected electro-magnetic field strength in the opening in the mounting member;
- a control signal generator receiving the field strength signal from the field strength sensor and the reference signal from the level control mechanism representing a specified electro-magnetic field strength set point;
- and
- the control signal generator forming a signal to regulate the power flowing from the electrical power supply to the magnetic field coil.
