Animal experiment device capable of providing intermittence low-oxygen environment

Abstract

The invention provides an animal experimental device used for providing an intermittent hypoxia environment. The device comprises an air controlling device and a breeding cabin, wherein an oxygen controlling electromagnetic valve (1), an air exhaust controlling electromagnetic valve (2) and a nitrogen controlling electromagnetic valve (3) of the air controlling device are provided with an air inlet and an air outlet respectively; the oxygen controlling electromagnetic valve (1) is electrically connected with an oxygen circulation control timer (4) to form an oxygen controlling unit; the nitrogen controlling electromagnetic valve (3) is electrically connected with a nitrogen circulation control timer (7) to form a nitrogen controlling unit; the oxygen controlling unit and the nitrogen controlling unit are connected in parallel and connected to a DC power supply (15); the air exhaust controlling electromagnetic valve (2) is connected with a rectifying diode and then connected to the oxygen controlling unit and the nitrogen controlling unit respectively; the breeding cabin is provided with an oxygen inlet, a nitrogen inlet and an air vent; the oxygen inlet is communicated with the air outlet of the oxygen controlling electromagnetic valve (1); the nitrogen inlet is communicated with the air outlet of the nitrogen controlling electromagnetic valve (3); and the air vent is communicated with the air inlet of the an air exhaust controlling electromagnetic valve. The device can be well applied to simulative experiments of sleep apnea.

Description

technical field [0001] The invention relates to an animal experiment device for providing intermittent hypoxic environment. Background technique [0002] The study of sleep apnea disease needs to provide animal experimental devices that can provide experimental animals with intermittent hypoxic environment to simulate repeated hypoxia and reoxygenation of sleep apnea. The reoxygenation means to restore the oxygen concentration. Existing devices of this type simply replace the supply of oxygen and nitrogen to achieve repeated hypoxia and reoxygenation, and cannot ensure that the breeding cabin is in a state of normal pressure, nor can it achieve accurate control of oxygen concentration and circulation rate, so it is necessary to provide a To overcome the above-mentioned shortcomings, it is best to provide an animal experiment device with low cost, simple structure and easy operation that provides an intermittent hypoxic environment.
