(Summary description)Medical low-temperature plasma equipment needs to be wary of the electric field biological effect plasma gas temperature: Clinical plasma medicine involves a very complex biological and chemical basis. Whether it is for clinical applications or surface applications of non-clinical plasma cleaning equipment, the transmembrane potential of the electric field in the plasma of the low-temperature plasma equipment and the temperature of the plasma gas have a non-negligible effect, so let Cheng Fengzhi and you briefly analyze it. Transmembrane potential of plasma discharge electric field of low-temperature plasma equipment: When the organism is in direct contact with the plasma discharge zone, the biological effect of the electric field needs to be considered. Take the pulseless electric field as an example. Relatively speaking, the average electric field intensity in the plasma is relatively low, especially the voltage applied to the biological material is much smaller than the voltage in the plasma region. Therefore, it is usually not enough to significantly damage the cell structure. . At the same time, the conductivity of the cytoplasm and intercellular substance is one million times higher than that of the cell membrane, so current can only pass through the intercellular substance, and the cell membrane will form a barrier outside the cell to limit the pressure drop in the cytoplasm. But when an electric current passes outside the cell, the voltage flowing along the outer surface of the cell will form a gradient, resulting in a transmembrane potential. When the transmembrane potential is greater than a certain value, the cell structure will be destroyed. Since the amplitude of the transmembrane potential depends on the size, shape and direction of the cell, the destructive ability of different cells is different. Plasma temperature of low-temperature plasma equipment: The plasma used in general medicine generally refers to low-temperature plasma. Its gas temperature generally does not exceed 60°C. The temperature is slightly higher than body temperature. It will not cause burns. It can increase blood circulation, relax pores, and can treat certain diseases. It plays a role in auxiliary treatment. However, if the plasma is not uniform, it is very likely to cause the temperature in the local area to rise, which will cause local burns. The plasma uniformity is a problem that should be paid attention to in clinical medical applications. In addition, when the plasma temperature is 6°C higher than the normal temperature, that is, it exceeds 43°C, the kinetic energy of cell membrane molecules may exceed the hydration energy, leading to supramolecular polymerization and structural degeneration. Therefore, the kinetic energy damage of the cell membrane under high temperature determines the speed of cell necrosis. In short, the biological and chemical basis involved in clinical plasma medicine is very complicated. In addition to the aforementioned factors such as ultraviolet rays, charged particles, transmembrane potential, and temperature, in actual clinical applications, comprehensive consideration and careful use are required. .
