Medically, high -frequency ultrasound (US) from i to 10 MHz is used for diagnosis and treatment. The sound waves from high -frequency USA are standing waves, and their penetration depth is limited, so in addition, the tissue is more affected by high -frequency US than internal organs. The particularity of standing sound waves is that they accumulate red blood cells (RBC) at nodes, and they are about to gather. In medical practice, the use of blood analyzers, with the help of artificial intelligence algorithms, determine the effects of various intensity and duration on the low -frequency USA of blood dynamics parameters, thereby revealing the possibility of RBC aggregate dissipation. [1]Essence When hemoglobin molecule enhances the gas exchange of the breathing surface on the entire surface area of the RBC, this is caused by the transmission sound waves caused by low -frequency U.
The exposure of the United States is very important for patients’ health. According to the standard of ultrasound society, the level of sound intensity of the frequency range of medical ultrasound diagnostic equipment must not exceed 1000 mW/ CM2Essence Keep in mind that as the ultrasound frequency decreases, its wavelength increases, and at the same time, the penetration rate (up to 100 kHz) US is more suitable for non -invasive treatment, but lack of effective means to produce this acoustic effect. The tissue attenuation coefficient and action depth of the sound intensity and biological medium are reduced. Contrary to the commonly used ultrasonic sensor, these ultrasonic sensors only generate the vibration mode of the vertical mode, and use the digital twins to our developed and patented low -frequency voltage agent [2] Operate in the radial vibration mode. This radial displacement increases the penetration of the voice signal, reduces the dispersion of the signal, and allows the acoustic effect of deeper biological tissues, so the development of the developed equipment can be used for treatment purposes.
The measurement of the physiological parameters of anesthesia sheep shows that the penetration of ultrasound in our developed equipment is 4 times higher than the equipment used so far so far [3]Essence The decrease in blood pressure is due to the decrease in the amount of blood volume exposed to the low -frequency US unit of blood, and the number of RBCs in the blood in the blood that is not affected by ultrasound is reduced. This significantly reduces blood viscosity, because the viscosity of human blood is proportional to the proportional proportional (RBC concentration), which is responsible for the transportation of oxygen and carbon dioxide. Research in the body of sheep shows that the saturation of the lung oxygen is increased by 10-15 %, and the blood pressure and heart rate have been reduced by 7 minutes.
In the future, the blood dynamics characteristics and the application of development equipment may be related to the possibility of destruction of cardiac valve plaques. By accurately focusing the low -frequency signal on it, promoting wound healing or guiding drugs to improve wound healing or using healing The process is more effectively encapsulated in the specific organs of the human body. The possibility of destroying the biofilm through ultrasound makes antibiotics more effective, and the possibility of improving brain circulation through additional carbon dioxide is also very hopeful, because due to low frequency exposure, hemoglobin not only transports more hemoglobin from the lungs, but also has also has a possession of the lungs, but also has also having it. More oxygen. But also from carbon dioxide from biological therapy.
