Description

Technical Field

[0001] The utility model belongs to the technical field of microwave hyperthermia machines, and particularly relates to a protection device for a microwave hyperthermia machine. Background Technique

[0002] A microwave hyperthermia machine utilizes microwave energy to make water molecules and ions in specific lesion tissues of the human body move locally and at high speed, thereby generating heat energy to denature the lesion tissues and restore normal circulation function. The microwave hyperthermia machine uses electromagnetic waves to heat the treatment part of the patient. After the electromagnetic waves enter the human tissue, there are two physical effects to convert electromagnetic energy into heat energy. One is that a large number of polar molecules in the tissue quickly twist with the change of the electromagnetic field direction in the alternating electromagnetic field to generate molecular friction and heat, and the other is that free electrons, ions and other charged particles in the tissue move along or against the electric field direction to generate Joule heat. When using high-frequency electromagnetic waves for hyperthermia, the high-speed twisting and friction of polar molecules in the electromagnetic field to generate heat is the main reason for the tissue temperature rise.

[0003] When the existing microwave hyperthermia machine is in use, there is a lack of protection for the microwave hyperthermia machine. When the user suddenly gets up or lifts a foot, it is easy to directly hit the inner wall of the microwave hyperthermia machine, which not only damages the machine but also easily causes injury to the user. For this reason, we propose a protection device for a microwave hyperthermia machine. Content of the Utility Model
