Problems solved by technology

[0007] Moreover, in the study of biological effects in complex electromagnetic environments, due to the lack of microwave composite irradiation devices, the current method is usually staggered in time, first irradiating microwaves of a certain frequency, then irradiating microwaves of another frequency, and finally irradiating microwaves of another frequency. Observe the biological changes of the sample, which is not rigorous in the experimental design, because the simultaneous compound irradiation of multiple microwaves may be much more harmful than the sequential irradiation of single microwaves

Abstract

The invention provides a microwave irradiation chamber, a microwave irradiation system and a microwave irradiation and real-time observation method. The microwave irradiation chamber comprises a shell and a shielding component, wherein a cuboid-shaped cavity is formed in the shell, a microwave receiving interface and a microwave absorption interface are arranged in the central positions of the two end walls of the shell, respectively, a first opening is formed in the central position of the top wall of the shell, and a second opening is formed in the central position of the bottom wall; the shielding component covers the first opening of the shell, and the center of the shielding component is provided with a through hole. According to the technical scheme of the invention, the microwave irradiation chamber can be directly connected into a real-time observation and analysis instrument to carry out biological index observation in real time, so that the microwave leakage is slight, and the cross-sectional area of the microwave irradiation chamber is adjustable, and therefore, the compound irradiation of microwaves with different frequencies can be realized.

Description

technical field [0001] The present invention relates to the field of microwave irradiation, in particular to a microwave irradiation cavity, a microwave irradiation system including the microwave irradiation cavity, and a microwave irradiation system for biological samples using the microwave irradiation system. The real-time observation method is used to realize compound irradiation and real-time observation of biological samples. Background technique [0002] Microwave technology is one of the major achievements in the development of modern science and technology. The health hazards and possible adverse effects of microwave radiation on organisms have attracted more and more attention and become an important research field. [0003] Microwave refers to electromagnetic waves with a frequency of 300MHz to 300GHz and a corresponding wavelength of 1m to 1mm. Electromagnetic waves in this frequency band, the energy of photons is not enough to ionize biological macromolecules o...
