Normal-pressure hypoxic cabin for interval hypoxic training and method for regulating oxygen concentration in hypoxic cabin

Abstract

The invention provides a normal-pressure hypoxic cabin for interval hypoxic training and a method for regulating oxygen concentration in the hypoxic cabin. A normal-pressure hypoxic cabin is provided, and the normal-pressure hypoxic cabin is communicated with a nitrogen source through a flow control component and a flow measurement component and is connected with an exhaust device; an oxygen concentration measuring device connected with a central control unit is provided, the flow measurement component is connected with the input end of the central control unit, and the central control unit is electrically connected with the flow control component; and a gas source cabin with a gas displacement function is provided, masks are arranged in the normal-pressure hypoxic cabin, the masks are respectively communicated with the gas source cabin through a non-return valve and an on-off valve of a gas suction pipe as well as a non-return valve and an on-off valve of an expiration pipe, and the gas source cabin is provided with a gas source input pipe and a gas flow output pipe. The normal-pressure hypoxic cabin provided by the invention has the advantages of simple structure, low manufacturing cost and high safety. The method provided by the invention can be used for regulating the pressure difference between the inside and outside of the hypoxic cabin by controlling the relative amountbetween the input nitrogen amount and exhaust amount, thereby realizing the function of regulating the oxygen concentration in the normal-pressure hypoxic cabin. The method is simple and easy to operate.

Description

technical field [0001] The invention belongs to a training device and its use method, in particular to a device for intermittent hypoxic training and a method for adjusting the oxygen concentration in a hypoxic chamber. Background technique [0002] Existing methods for performing intermittent hypoxic training generally include: allowing trainees to intermittently change gas in a hypobaric chamber with a lower partial pressure of oxygen or to breathe through a mask with a higher partial pressure of oxygen in a hypobaric chamber environment. The training method can also be used to train the trainees in a non-cabin environment, using intermittent breathing training between the gas with a lower oxygen concentration and the gas with a higher oxygen concentration in the mask. Although the former training method using the hypobaric chamber will make the hypoxic physiological response during training more realistic, it has the disadvantages of high cost of the hypobaric chamber and...
