Claim 6

The apparatus of claim 1, wherein the output frequency of said microwave source is 915 MHz, and the maximum output power of said microwave source is 2 kw.

Claim 7

A non-contact type of microwave deep-diathermy apparatus adapted for diathermizing a medium including a surface, comprising: a microwave source including an output for providing microwaves, said microwave source having a continuously adjustable output power with a maximum output power of more than 1.2 kw and an output frequency range of 600-1500 MHz; a microwave radiator having an input port and an output port with the input port coupled with the output of said microwave source for receiving said microwaves from said microwave source and radiating them through the output port thereof, said microwave radiator adapted for radiation toward said medium and being non-contact with the medium, wherein a distance between the surface of the medium and said output port of the microwave radiator is 20-70 cm; microwave focusing means provided in front of said output port of said microwave radiator and attached thereto for focusing said radiating microwave on a point positioned in the medium, wherein said microwave focusing means comprises a casing and a plurality of small metal balls placed in and supported by said casing and arranged as a convex lens shape with the balls being arranged in a spaced dot array; temperature-measuring means for measuring a surface temperature and deep tissue temperatures of said medium; and computer based control and display means coupled with said temperature-measuring means and said microwave source respectively, and responsive to a temperature signal from said temperature-measuring means for displaying a temperature value measured by said temperature-measuring means and providing a corresponding control signal for said microwave source to control and adjust the output power of said microwave source and consequently change the temperature of a diathermized position in the medium to be diathermized.

Claim 8

A non-contact type of microwave deep-diathermy apparatus adapted for diathermizing a medium including a surface, comprising: a microwave source including an output for providing microwaves, said microwave source having a continuously adjustable output power with a maximum output power of more than 1.2 kw and an output frequency range of 600-1500 MHz; a microwave radiator having an input port and an output port with the input port coupled with the output of said microwave source for receiving said microwaves from said microwave source and radiating them through the output port thereof, said microwave radiator adapted for radiation toward said medium and being non-contact with the medium, wherein a distance between the surface of the medium and said output port of the microwave radiator is 20-70 cm; microwave focusing means provided in front of said output port of said microwave radiator and attached thereto for focusing said radiating microwave on a point positioned in the medium, wherein said microwave focusing means comprises a casing and a plurality of small metal balls placed in and supported by said casing and arranged as a convex lens shape with the balls being arranged in a spaced dot array; temperature-measuring means for measuring a surface temperature and deep tissue temperatures of said medium; and computer based control and display means coupled with said temperature-measuring means and said microwave source respectively, and responsive to a temperature signal from said temperature-measuring means for displaying a temperature value measured by said temperature-measuring means and providing a corresponding control signal for said microwave source to control and adjust the output power of said microwave source and consequently change the temperature of a diathermized position in the medium to be diathermized.
