The direct result of hyperthermia is to cause vasodilation in local tissues of the human body, strengthen blood flow, open up blocked capillaries, and increase blood perfusion to human tissues. The efficacy of this type of instrument is directly related to the promotion of tissue cell metabolism in the body under the condition of improved blood circulation. Therefore, the degree of blood circulation improvement directly corresponds to the curative effect. The most common thermotherapy instruments are shortwave and ultrashortwave, microwave and infrared physiotherapy instruments.
Shortwave and ultrashortwave: The penetrating energy is the strongest, and its energy can directly enter the human body tissues at a depth of tens of centimeters. Such equipment is widely used in hospitals. However, it is necessary to grasp the level of energy when using it, because shortwave has the feature that fat absorption is 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, the penetration ability of microwave is worse. Generally speaking, electromagnetic wave has half-wave penetration ability. The half-wave penetration ability of 12 cm wavelength microwave is 5-6 cm, so microwave therapeutic equipment It is more suitable for the physiotherapy of osteoarthritis and superficial soft tissue inflammatory diseases, but the biggest advantage of microwave is that the absorption capacity of human bones, muscles and adipose tissues is very close. Experiments have confirmed that under the action of microwaves, different tissues of the human body can absorb microwaves. The absorptive capacity has the following relationship: fat: muscle: bone=1:1:1. Therefore, the physiotherapy effect of microwave on shallower tissues is significantly better than shortwave and ultrashortwave. Hospitals at all levels highly recognize the efficacy of microwave on osteoarthritis, prostatitis, pelvic inflammatory disease, rhinitis, etc. Family microwave therapy devices have begun to enter many families, and because of the high cure rate, they are highly evaluated and recognized by users.
