Abstract

The invention relates to the technical field of animal test equipment, in particular to a transparent observable box for generating a chronic intermittent hypoxic state by applying a numerical controltechnology. According to the equipment, a nitrogen conveying pipe and an exhaust pipe which are communicated with the interior of a test box are connected to the two end parts of the closed test boxrespectively; the flow of an air inlet valve and an exhaust valve are designed and controlled through a computer application program, and a nitrogen conveying pipe is connected to a nitrogen conveyingbottle; and nitrogen is added into the closed test box, so that air in the closed test box is exhausted from the exhaust pipe, oxygen in a box is rapidly exhausted, the content of the oxygen in the box is reduced, an experimental animal placed in the box body is in an intermittent hypoxia state, and a chronic intermittent hypoxia animal model is established. The device enables the oxygen contentin the test box to automatically simulate the state of chronic intermittent oxygen deficiency in the human body according to experimental requirements.

Description

technical field [0001] The invention relates to the technical field of animal test equipment, in particular to a digitally controlled chronic intermittent hypoxia chamber. Background technique [0002] Among the main gas components in the air, the oxygen content is between 19-21% at low altitudes, and the rest is dominated by nitrogen, about 80%. Chronic intermittent hypoxia is a state of obstructive apnea in human sleep. Due to the relaxation of the muscles of the throat and tongue, the airway of the throat is partially blocked, or completely blocked in a short period of time, resulting in a decrease in oxygen exchange. , the oxygen content in the blood decreases, and a state of systemic hypoxia occurs. The brain is the most vulnerable to damage due to its greatest need for oxygen. The state of chronic hypoxia will cause chronic hypoxic changes in the brain and systemic organs, resulting in the death of nerve cells and damage such as brain atrophy. The chronic intermitte...
