The working principle of the mold incubator is how the mold incubator is an energy form. When a certain dose of ultrasound is transmitted through the body, the interaction between them is. Ultrasonic is a kind of elastic mechanical wave in the medium. It is a form of volatility, so it can be used to detect physiological and pathological information of the human body, both to diagnose ultrasound.
At the same time, it is a form of energy. When a certain dose of ultrasound is transmitted through the body, the interaction between them can cause changes in the function and structure of the organism, that is, the ultrasonic biological effect. The effects of ultrasound on cells are mainly thermal effects, cavitation effects and mechanical effects. The thermal effect is that when the ultrasound propagates through the medium, the friction hinders the molecular vibration caused by the ultrasound, converting part of the energy into local high heat, because the critical lethal temperature of normal tissue is 45.7 ° C, and the tumor tissue is more sensitive than normal tissue. Therefore, at this temperature, the metabolism of tumor cells is impaired, and DNA, RNA, and protein synthesis are affected, thereby killing cancer cells and normal tissues are not affected. The cavitation effect is that under the irradiation of ultrasound, vacuoles are formed in the living body, and mechanical shear pressure and turbulence are generated along with the vibration of the vacuole and its violent explosion, which causes the tumor to hemorrhage and the tissue to collapse and cause necrosis.
In addition, when cavitation bubbles burst, instantaneous high temperature and high pressure are generated, which can thermally dissociate water vapor to produce .OH radicals and .H atoms. The redox reaction caused by .OH radicals and .H atoms can lead to polymer degradation. , enzyme inactivation, lipid peroxidation and cell killing. The mechanical effect is the primary effect of ultrasound. During the propagation process, the medium particles alternately compress and stretch to form a pressure change, causing damage to the cell structure. The strength of the killing effect is closely related to the frequency and intensity of the ultrasound.
The principle of ultrasonic cell disruption is not too mysterious and complicated. Simply put, the electric energy is converted into sound energy through the transducer. This energy is turned into a dense small bubble through the liquid medium. These small bubbles burst rapidly and produce the same energy as a small bomb, thus breaking the cell. The role of substances.
