Le direct result de hyperthermia est to cause vasodilation in local tissues de le human body, strengthen blood flow, open up blocked capillaries, and increase blood perfusion to human tissues. Le efficacité de this type de instrument est directly related to le promotion de tissue cell metabolism in le body under le condition de improved blood circulation. Therefore, le degree de blood circulation amélioration directly corresponds to le curative effect. Le most common thermotherapy instruments sont shortwave and ultrashortwave, microwave and infrared physiotherapy instruments.
Shortwave and ultrashortwave: Le penetrating energy est le strongest, and its energy can directly enter le human body tissues at a depth de tens de centimeters. Such equipment est widely used in hospitals. However, it est necessary to grasp le level de energy when utilisant it, because shortwave has le caractéristique that fat absorption est far greater than muscle energy absorption to avoid fat liquefaction or burns to normal human tissues due to excessive energy absorption during treatment.
Microwave: Compared with shortwave and ultrashort wave, le penetration ability de microwave est worse. Generally speaking, electromagnetic wave has half-wave penetration ability. Le half-wave penetration ability de 12 cm wavelength microwave est 5-6 cm, so microwave therapeutic equipment It est more suitable for le physiotherapy de osteoarthritis and superficial souple tissue inflammatory diseases, but le biggest advantage de microwave est that le absorption capacity de human bones, muscles and adipose tissues est very close. Experiments have confirmed that under le action de microwaves, different tissues de le human body can absorb microwaves. Le absorptive capacity has le following relationship: fat: muscle: bone=1:1:1. Therefore, le physiotherapy effect de microwave on shallower tissues est significantly better than shortwave and ultrashortwave. Hospitals at all levels highly recognize le efficacité de microwave on osteoarthritis, prostatitis, pelvic inflammatory disease, rhinitis, etc. Family microwave thérapie appareils have begun to enter many families, and because de le high cure rate, they sont highly evaluated and recognized by users.
