Abstract
Description
Technical Field
[0001] This utility model specifically relates to the field of laboratory animal husbandry technology, and more specifically to an animal isolation hyperbaric chamber. Background Technology
[0002] Animal experiments are an indispensable part of many scientific research fields, such as medicine and biology. For studies involving respiratory diseases and neonatal development, it is often necessary to place experimental animals (such as mice and rats) in a hyperoxia environment for observation. In researching neonatal lung injury models, newborn suckling mice need to be exposed to a hyperoxia environment to simulate the lung damage caused by prolonged oxygen inhalation in premature infants in clinical practice. However, continuous hyperoxia exposure can damage the mother mice and reduce their lifespan. Furthermore, in some experiments, to accurately study the physiological responses of artificially fed suckling mice and mother mice under different environmental factors, it is necessary to separate the mother and suckling mice. For example, to study the postpartum recovery of mother mice in a normal oxygen environment and the growth and development of suckling mice in a hyperoxia environment, this separation can avoid interference between the mother and suckling mice and more accurately control experimental variables.
[0003] Chinese Utility Model Patent Publication No. CN 214758514 U discloses a high-safety isolation box for animal experiments. This high-safety isolation box for animal experiments incorporates a second servo motor. The output shaft of the second servo motor drives a support block to rotate, which in turn drives a fan blade, increasing airflow inside and outside the box. This effectively removes odors and ensures clean air inside the box. A fixed shaft and a second bearing are used, and the rotation of the second bearing on the fixed shaft surface, along with fixing bolts, allows for easy installation and fixation of the collection frame. However, this high-safety isolation box for animal experiments lacks a partition, making it difficult to separate the internal space. This hinders the isolation and observation of animals in different situations, such as mother mice and suckling mice, resulting in poor practicality. Furthermore, the high-concentration oxygen on the suckling mouse side can easily leak to the mother mouse side, affecting normal use. Utility Model Content
