Description

Technical Field

[0001] The invention relates to the technical field of leukemia model mice, and in particular to a leukemia model mouse protection device. Background Art

[0002] Researchers often study the changes in vital signs of leukemia model mice in the air, as well as the reactions and physical changes they exhibit after being injected with various leukemia research interventions. However, the treatment environment for leukemia model mice is different from that for leukemia patients. Leukemia model mice need to be placed in a protective device with few bacteria and dust.

[0003] Chinese patent publication number CN109975484B discloses an air quality measurement and control device for a leukemia model nursing ward, comprising a model ward, a front panel, a control panel, and a first electric telescopic rod. An observation window is fixedly mounted on the left side of the front of the model ward by embedding, and a front panel is fixedly mounted on the front of the model ward to the right of the observation window. A control panel is fixedly mounted on the front of the front panel. The air quality measurement and control device for the leukemia model nursing ward utilizes the characteristics of mice, using fluorescent lamps to drive the mice to move. At the same time, sterile and dust-free air is introduced into the model ward, placing the model mice in a similar air environment to that of leukemia patients, thereby improving the accuracy of sample performance characteristics. The number of bacteria that fall onto the culture medium can be used as a comparison of the bacterial content within the device, making it easier for researchers to study the impact of the amount of bacteria in the air on the model mice, ultimately improving the accuracy of research. The device has a simple structure and a reasonable design, making it easy to promote.

[0004] The above-mentioned device simulates leukemia patients in a similar air environment by introducing sterile dust-free air into the model ward, and uses the number of colonies on the culture medium as a comparison for the bacterial content inside the device to study the impact of the bacterial number on mice. However, before use, the device directly places the culture medium and mice into the model ward, and then introduces sterile dust-free air. In this way, the culture medium is first easily contaminated by bacteria in the outside air, which will reduce the research accuracy when studying the number of colonies on the culture medium. When placing mice, the outside air containing a large amount of bacteria will be substituted into the model ward, further reducing the accuracy of the research. Therefore, the present application provides a leukemia model mouse protection device with air quality measurement and control function to meet the needs. Summary of the Invention
