The power of the heating lamp is too high, which is easy to cause local burns. Some special needs must also be kept at a distance of more than one meter, while the power of medical baking utensils is much smaller.
The infrared frequency width emitted by the heating lamp is too wide, and some frequencies are not used or the effect is not good, so the required frequency will be too narrow, which seems inadequate. However, medical baking equipment is relatively concentrated.
Medical infrared rays can be divided into near infrared rays and far infrared rays. It contains heat energy, and the heat of the sun is mainly transmitted to the earth through infrared rays. Medical infrared mainly includes near infrared, short-wave infrared, medium-wave infrared and long-wave infrared. ?
Near-infrared or short-wave infrared, with a wavelength of 0.76 ~ 1.5 micron, penetrates into human tissues for about 5 ~ 10 mm. Far-infrared or long-wave infrared, with a wavelength of 1.5 ~ 400 micron, is mostly absorbed by superficial skin, and the depth of penetration into tissues is less than 2mm.
Extended data:
Far infrared rays have strong penetrating power and radiation power, and have obvious temperature control effect and vibration effect, which are easily absorbed by objects and converted into internal energy of objects. After being absorbed by human body, far infrared rays can make water molecules in the body vibrate, activate water molecules and enhance their intermolecular binding force, thus activating biological macromolecules such as protein and making biological cells at the highest vibration level.
Due to the vibration of biological cells, far-infrared heat energy can be transmitted to the deeper layer of human skin, and the temperature below the deep layer rises, and the generated warmth is emitted from the inside out. The intensity of this effect can dilate capillaries, promote blood circulation, strengthen metabolism among tissues, increase the regeneration ability of tissues, improve the immune ability of the body, and adjust the abnormal excitement of the spirit, thus playing a role in medical care.
