DB0117 hangover experimental video analysis system Introduction: The tail suspension tester is mainly used for the study of antidepressants, ** and analgesics. The instrument is suitable for use in rats, mice or other laboratory animals by hanging the tail of the animal and hanging its head down to record a series of parameters during the desperate state of motion of the animal in the environment. The product provides a data communication interface to the PC, and analyzes the experimental process with special test software and prints the experimental report. It can be widely used in medical colleges and research institutes of universities and colleges for experimental teaching and research on antidepressants. Experimental principle: The animal is hanged by fixing the tail of the animal, and the animal struggles in the environment to try to escape and cannot escape, thereby providing an unavoidable oppressive environment. After a period of experiment, the animals in the environment are recorded. A series of parameters in the process of producing a desperate state of immobility, the typical "immobility state" exhibited by an animal reflects a phenomenon known as "behavior despair," a desperate model of behavior and depression. Similar, and sensitive to most antidepressants, and its efficacy is significantly related to clinical efficacy, it is widely used in the primary selection of antidepressants. Features: 1. The product is advanced in function, synchronized with foreign advanced products, using computer vision related algorithms to measure the intensity and time of the animal struggling after the tail is suspended. 2. Up to 16 experimental mice can be tested simultaneously, saving time and time 3. Side image tracking algorithm technology to ensure the authenticity of the results 4. The automation of the experimental process is realized, which avoids the subjective error introduced by manual counting and the interference to the experimental animals, and increases the objectivity and reliability of the experimental results. 5. Keep the video of the experiment process, and the experimenter can play back the manual check. 6. It can record video images at regular intervals, display indicators in various ways, and provide the function of exporting track maps, track coordinate points and index results. 7. Support AVI compression format, high compression ratio, can effectively reduce storage space, and is conducive to long-term experimental observation. 8. For scientific research and computer-aided instruction (CAI), it can record original video images and provide complete experimental database functions as a real record of research and materials for future teaching demonstrations. 9. Video analysis can be performed under starlight conditions, with less interference to animals, and starlight conditions are consistent with the living habits of rodents. 10. Adopt open and modular design, the system is highly expandable, and can be connected with other analysis modules. The track point coordinate sequence data and index results can be imported into Excel, which is convenient for users to analyze in statistical software such as Excel, SPSS and SAS. Further analysis and processing. 11. New medical type soundproof box, * largely eliminate the influence of the external environment and experimenters 12. Analysis flexibility, support time period analysis, support timed termination and manual termination, and has a rich display mode, which can adopt various display modes such as trajectory map, parameter index, curve, and histogram for animal movement, and can generate complete Report for printout. 13. Spatial resolution* can be as high as 640x480 pixels, time resolution* can be as high as 25 frames/second (usually 15 frames/second), and the measured index results are highly accurate.
