Laser energy can not only penetrate human skin, fat, muscle, blood vessel wall and other tissues, but also do no harm to human tissues and cells. The laser emitted by Zheng Anxin cerebrovascular therapeutic instrument belongs to low-energy laser, and its irradiation power density is far less than the damage threshold to the body and blood. When performing extravascular laser irradiation, the laser penetrates the human body and will not cause any harm to the body. When the blood vessels under the body surface are irradiated, the laser energy of about110 penetrates the blood vessel wall and other tissues, and is absorbed by the blood, which has a therapeutic effect.
1. The occurrence of ischemic diseases is not only the disorder and obstacle of blood flow, but also the disorder and obstacle of oxygen transport, which is considered as the main cause of ischemic diseases at present. Therefore, to judge the curative effect of any therapy used to treat ischemic diseases, the main criterion should be whether the disorder and obstacle of oxygen transmission can be corrected and improved, and whether the oxygen transmission ability of blood can be restored and improved.
2. The human body is an organic and open giant system, and the physiological function of the human body is not only influenced by the communication and adjustment between the functional systems in the body, but also by external substances, energy and information. The instrument takes laser (sometimes accompanied by oxygen inhalation) as external factors, stimulates the body fluid system (including blood, lymph and saliva), nervous system and meridian system, and can effectively regulate the functions of human tissues and organs and the whole body, which embodies this theory.
3. Irradiating the body with weak laser with appropriate wavelength and certain power density can cause the body's response, that is, laser biological effects, such as biological stimulation effect and photochemical effect, and then use these biological effects to treat diseases and health care. These effects have certain rules. According to these, the functional parameters of this instrument are selected and set, so as to ensure the effect of treatment and health care. If you have ischemic and hypoxic diseases, you should go to the hospital for treatment in time to ensure that the condition is controlled and improved. However, because the treatment and rehabilitation of such diseases need a long course of treatment, most patients cannot be hospitalized for a long time, and it is not appropriate to take drugs for a long time. Some patients often relapse after a period of time after their condition is controlled and improved, so they need repeated treatment or even lifelong medication. With the laser therapeutic instrument, patients can get auxiliary treatment and long-term care at home, thus consolidating and improving the curative effect, further alleviating the illness, promoting rehabilitation, reducing medication, avoiding the toxic and side effects of drugs, enhancing immunity and preventing the recurrence of diseases. If the instrument is used for nursing when symptoms appear, the deterioration of the disease can be controlled in time, the pathological process can be reversed and the effect of self-rehabilitation can be achieved. Laser therapeutic instrument is a widely used health care method for middle-aged and elderly people. Middle-aged and elderly people in sub-health state can adjust blood lipid, blood sugar and blood pressure, restore normal physiological function and improve immune function, thus preventing the occurrence of ischemic and hypoxic diseases. For ordinary middle-aged and elderly people, it has the effects of delaying aging, promoting digestion, strengthening the body, calming the nerves and helping sleep.
