Animal Cage Rack for Electromagnetic Wave Exposure {Animal Cage Rack for Electromagnetic Wave Exposure}

The present invention relates to an electromagnetic animal experiment cage rack device, in particular, by assembling a rectangular parallelepiped cage rack made of synthetic resin, and then fastening and fixing a guide rail to the upper and lower portions of the cage rack, and fastening and fixing a plate-shaped cage lead to the top of the guide rail. It is closed, and the animal is accommodated in the guide rail, and the cage for ingesting food and water is combined, and it is sequentially piped at the top and bottom of the cage rack to lower the water pressure so that the experimental animals inside the cage can easily ingest sterilized water. By draining the sterilized water heated by the sterilized water to maintain the temperature of the sterilized water, and equipped with a water supply and drainage device to supply clean sterilized water by removing foreign substances inside, mobile phone electromagnetic wave It is configured to conduct a carcinogenicity test according to exposure.

Modern people are intentionally or unintentionally exposed to various electromagnetic wave environments by the use of various electronic devices, and the exposure environment is rapidly changing due to the development of advanced electronic devices and technologies, of which the exposure of electromagnetic waves is wavelength (wave length). Although it is exposed to the human body in various forms depending on the frequency and frequency, research results on harmfulness are only being studied in limited areas, and there are many results that are difficult to judge in terms of scientific reliability, increasing public anxiety about electromagnetic waves. Therefore, it is necessary to secure reliable hazardous data.

In the case of mobile phone electromagnetic waves that are most commonly exposed in the living environment, the IARC (International Cancer Research Institute) classified carcinogenicity as a carcinogenic substance, class 2B, and anxiety about electromagnetic waves spread. The possibility of occurrence of malignant glioma in the brain and schwannoma in the heart was suggested through a carcinogenicity test. Recently, the problem of harmfulness to the human body due to the rapid increase in the environment of exposure to electromagnetic waves caused by the Internet of Things, electric vehicles and solar power generation, etc. As it is expected to be a social problem, there is a need to solve social problems related to safe use of electronic devices and harmfulness to the human body.

In order to identify the human risk caused by such various electromagnetic waves, a test to evaluate toxicity and carcinogenicity to evaluate the risk of toxicity in the human body is conducted using rodents such as rats and mice.

In order to conduct experiments using such electromagnetic wave rodents (rats and mice), it is necessary to provide a breeding device for efficiently breeding and managing animals by maintaining test conditions such as appropriate temperature, humidity and ventilation.

The prior art of such a cage for managing experimental animals includes Registration Patent No. 10-0932115 (Name of Invention: Experimental Animal Breeding Device) and Registration Patent No. 10-1480848 (Name of Invention: Ventilation Breeding Device using Cooling and Heating Means). Is being presented.

In such prior art laboratory animal breeding equipment, cross-contamination is prevented because one-way airflow is evenly formed in the cage, and a pleasant breeding environment is created by effectively reducing odor by increasing the number of ventilation inside the cage. In addition, because the airflow guiding member that evenly forms one-way airflow rotates back and forth and is detachable, convenience and efficiency for cleaning and management can be greatly obtained, so that the breeding equipment can be managed efficiently. Value can be created.

However, such a prior art effectively reduces the odor emitted by experimental animals by allowing a part of the airflow flowing along the open upper surface of the cage to flow out along the bottom of the cage, thereby creating a pleasant breeding environment, and experimenting in an optimal state. It is intended to raise healthy animals necessary for the experiment and supply them to various experimental subjects, which is not suitable for experimental research to identify risks caused by electromagnetic waves by supplying electromagnetic waves generated from mobile phones to experimental animals.

In addition, the individual ventilation breeding device using the cooling and heating means of the prior art, since cross-contamination is formed evenly distributed in the cage in one direction, creates a pleasant breeding environment to obtain reliable experimental results as well as cooling and heating means. Due to the cooling and heating airflow generated through the airflow, it facilitates the movement of the airflow in one direction, and there is also an effect of greatly reducing the energy generated by maintaining the constant temperature and humidity inside the sterile breeding room by using the energy generated through the cooling and heating means.

However, such prior art also has a basic problem that it is not suitable for experimental research to identify risks caused by electromagnetic waves by supplying electromagnetic waves generated from mobile phones to experimental animals.
