Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, in particular to a radiation performance and radiation range indicator of a microwave physiotherapy probe. Background Art

[0002] Microwave therapy is a type of physical therapy that uses microwave energy to treat human tissue. When microwave energy reaches the target tissue, the water molecules in the tissue absorb the microwave energy and convert it into heat energy. The generation of this heat energy can cause the temperature of the target tissue to rise, thereby achieving therapeutic effects, such as promoting blood circulation, relieving pain, and promoting tissue repair.

[0003] Microwave therapy equipment usually consists of a microwave generator, a controller, a transmission cable, and a microwave therapy probe. The microwave therapy probe is an important component for microwave energy to act on the human body. Due to the characteristics of microwave energy, the performance of the therapy probe and the radiation range acting on the human body are difficult for operators to monitor during use. Operators generally adjust the treatment parameters based on experience to ensure the treatment effect and safety according to specific treatment needs and patient conditions. Therefore, medical risks such as ineffective treatment and overtreatment often occur. Overtreatment causes hundreds of burns every year. Utility Model Content
