Embodiment Construction

[0044] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown so that this disclosure will fully convey the scope of the invention to those skilled in the art. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

[0045] A kind of intermittent hypoxia system of the present invention, see figure 1 and figure 2 , which simulates hypoxia by increasing the concentration of nitrogen in the air and reducing the oxygen content in a short period of time. After a few seconds, the oxygen content in the air is restored to end the short-term hypoxia. This is a cycle to simulate intermittent hypoxia environment.

[0046] Such as figure 1 As shown, the simulation experiment of intermittent hypoxia is carried out in a sealed box body 1, and the top of the sealed box body 1 has an openin...

Abstract

The invention discloses an intermittent hypoxia system comprising a sealing tank (1), an oxygen concentration detector (2), a nitrogen flow control valve (4), an air flow control valve (5), an in-box gas replacement control valve (6) and an air pump (7), wherein the nitrogen flow control valve (4), the air flow control valve (5), the in-box gas replacement control valve (6) and the air pump (7) are connected with a PLC (programmable logic controller) (3), the oxygen concentration detector (2) is arranged at the top of the sealing tank (1) and distant from a sealing cover (11), the left side and the right side of the sealing tank (1) are provided with nitrogen inlets (41 and 42) which are connected with a nitrogen gas source (43) connected with the nitrogen flow control valve (4) externally, the front side wall of the sealing tank (1) is provided with an air inlet (51) connected with the air pump (7) connected with the air flow control valve (5) externally, and the rear side wall of the sealing tank (1) is provided with an air outlet (61) connected with the in-box gas replacement control valve (6) arranged externally. The intermittent hypoxia system is capable of simulating experiment environment of intermittent hypoxia.

Description

technical field [0001] The invention relates to an intermittent hypoxia system. Background technique [0002] When organisms snore or have a heart attack, intermittent hypoxia occurs, and intermittent hypoxia can also cause cell damage. The observation of intermittent hypoxia in cells or organisms is of great significance for clarifying the mechanisms of cell damage and even brain damage, and for finding prevention and treatment countermeasures. Currently there is no manufacturer producing such a system for observing intermittent hypoxia. Contents of the invention [0003] The object of the present invention is to provide an intermittent hypoxia system for simulating the experimental environment of intermittent hypoxia. [0004] The purpose of the present invention is achieved like this: [0005] The present invention is an intermittent hypoxia system, which includes a sealed box with a sealed cover, an oxygen concentration measuring and controlling device, a PLC (progr...
