Abstract

Microwave hyperthermia treatment device includes a microwave generation unit, a power supply unit, and a control unit including an exposure-time actuation timer, an intermittent actuation timer, a second-device connecting terminal, and a remote switch. Two microwave hyperthermia treatment devices are connected with each other via the second terminal connecting terminals for simultaneous use flanking the torso along either side of an affected area, whereby superposed strong microwaves are irradiated. The temperature of tumor(s) in the affected area can thereby be brought to about 43° C. in about 1 minute, rendering lengthy treatment periods unnecessary and thus alleviating temperature stress on the patient. Two remote-control switches to the control unit can be provided, one of which may be given to a patient for use as an emergency stop switch, eliminating the necessity of having to insert a temperature sensor in the body, which also alleviates the burden on the patient.

Claims

1. A microwave hyperthermia treatment device comprising:

a generation unit for generating microwaves;

a power supply unit for driving the generation unit; and

a control unit for controlling the power supply unit, the control unit including

an exposure-time actuation timer,

an intermittent actuation timer,

a second-device connecting terminal, and

a remote switch connected to a remote-control cord.

3. The microwave hyperthermia treatment device as set forth in claim 1, wherein the generation unit for generating microwaves has a rated output of 750 W at 2,450 MHz.

5. A microwave hyperthermia treatment system wherein two microwave hyperthermia treatment devices according to claim 1 are connected via the second-device connecting terminals for simultaneous use flanking the torso of a patient along both sides of an affected area.

7. A microwave hyperthermia treatment system wherein two microwave hyperthermia treatment devices according to claim 3 are connected via the second-device connecting terminals for simultaneous use flanking the torso of a patient along both sides of an affected area.

9. A microwave hyperthermia treatment system wherein four microwave hyperthermia treatment devices according to claim 1 are connected via the second-device connecting terminals for simultaneous use flanking the torso of a patient along both sides of two affected areas.

11. A microwave hyperthermia treatment system wherein four microwave hyperthermia treatment devices according to claim 3 are connected via the second-device connecting terminals for simultaneous use flanking the torso of a patient along both sides of two affected areas.

2. A microwave hyperthermia treatment device comprising:
