Abstract
Description
Technical Field
[0001] The utility model relates to the field of moxibustion pens, and particularly to a moxibustion pen circuit. Background Art
[0002] The effect of moxibustion on the human body is mainly due to the antioxidant substances in the products of moxa combustion, which adhere to the skin at acupoints and act by penetrating into the body through moxibustion heat. Modern research has confirmed that the heat generated during moxibustion is an infrared ray, a very effective physical factor suitable for treating the body. According to the principle of physics, any object can emit and absorb infrared rays, and the human body is no exception. The penetration depth of near-infrared rays into the human body is deeper than that of far-infrared rays, up to 10 mm at most, and is absorbed by the body. The radiation energy spectrum generated during moxibustion is infrared rays, and near-infrared rays account for the main component. Near-infrared rays can stimulate the hydrogen bonds of biomolecules in human acupoints, producing a stimulated coherent resonance absorption effect, and transmitting the energy required by human cells through the neuro-humoral system. The infrared radiation during moxibustion can provide the necessary energy for the metabolic activities and immune functions of body cells, and can also provide activation energy for diseased cells lacking energy. When moxibustion is applied to acupoints, its near-infrared radiation has a high penetration ability and can better deliver energy to the lesion site through the meridian system, indicating that acupoints have the function of radiation resonance absorption;

[0038] The key parameters of wheat-grain moxibustion are as follows: the temperature is 47°C / 49°C / 52°C; the technician gently touches the acupoint with a small area at the tip of the moxibustion pen tip, and moves it away immediately when the patient feels burning pain. Each contact is one moxibustion cone; the acupoint can be moxibusted 3, 5, 7 times, etc.
