Ultrasonic therapy machine machinery


Ultrasonic vibration transducer can cause the movement of substances in tissue cells. Due to the fine massage of ultrasound, the cytoplasm flow, cell oscillation, rotation, friction, and thus the effect of cell massage, also known as "internal massage" is unique to ultrasonic therapy. Characteristics can change the permeability of cell membrane, stimulate the dispersion process of semi-permeable membrane, promote metabolism, accelerate blood and lymph circulation, improve cell ischemia and hypoxia, improve tissue nutrition, change protein synthesis rate, and improve regeneration function.


Ultrasonic therapy device 


Human tissue has a relatively large absorption capacity for ultrasonic energy, so when the ultrasonic wave propagates in human tissue, its energy is continuously absorbed by the tissue to become heat, and as a result, the temperature of the tissue itself rises. That is, endogenous heat. Ultrasound warming can increase blood circulation, accelerate metabolism, improve local tissue nutrition, and enhance enzyme activity. In general, the thermal effects of ultrasound piezo disk crystal are marked by bone and connective tissue, with minimal fat and blood.

Both the mechanical and thermodynamic effects of ultrasound can trigger several physicochemical changes.


a. Dispersion: Ultrasound can improve the permeability of biofilm, and the permeability of potassium and calcium ions changes strongly. Thereby enhancing the diffusion process of biofilm, promoting material exchange and improving tissue nutrition.


b. Thixotropy: Under the action of ultrasound, the gel can be converted into a sol state. Softening effects on muscles, tendons, and pathological changes are associated with tissue water deficits. Such as rheumatoid arthritis lesions and treatment of degenerative lesions of joints, tendons, and ligaments.


c. Cavitation: cavitation formation, or maintaining a stable one-way vibration, or secondary expansion to collapse, cell function changes, intracellular calcium levels increase. Fibroblasts are activated, protein synthesis is increasing, vascular permeability is increased, angiogenesis is accelerated, and collagen tension is increased.


d. Polymerization and depolymerization: Small molecule polymerization is the process of synthesizing multiple identical or similar molecules into one larger molecule. Macromolecular depolymerization is the process of turning macromolecular chemicals into small molecules. It can increase the activity of hydrolase and proenzyme in the joint.


e. Anti-inflammatory repairs cells and molecules: Under the action of ultrasound Pzt ceramic disc, the PH value of tissue can be developed to alkaline. Relieve local acidosis associated with inflammation. Ultrasound can affect blood flow, producing inflammatory effects, inhibit and play an anti-inflammatory role. Moving white blood cells and promotes angiogenesis. Thereby, the process of cleaning, activating and repairing the damaged cell tissue is achieved.
