Description

Pressurized plateau breathing system and device thereof The invention relates to the technical field of breathing auxiliary equipment, in particular to a pressurized breathing system and a pressurized breathing device suitable for a plateau environment. Background Under the action of the gravitational force, the earth's surface atmospheric density and pressure decrease with increasing altitude. The sea level atmospheric pressure is 1atm (1 standard atmospheric pressure, 101.3 kPa), the altitude is about 0.8atm (80.9 kPa) at 1800 m, the human body starts to develop an uncomfortable reaction, about 0.7atm (70.6 kPa) at 2700 m, about 0.6atm (60.52 kPa) at 3600 m, obvious dyspnea occurs, about 0.5atm (50.44 kPa) at 4500 m, which may cause a serious altitude reaction. The root cause of hypoxia in the plateau environment is that although the volume fraction of oxygen in air (about 21%) is substantially unchanged, as the air pressure decreases, the total number of gas molecules decreases and the oxygen partial pressure decreases proportionally. The human breath maintains the same volume of gas, but the total number of inhaled oxygen molecules decreases, resulting in a decrease in blood oxygen saturation. The prior highland oxygen supply technology mainly comprises the following steps: 1. oxygen supply of an oxygen bottle is inconvenient to carry, has limited capacity and depends on oxygen source supplement; 2. oxygen supply of the oxygenerator, namely heavier equipment, high power consumption and electric power support; 3. Pulse oxygen supply, namely detecting respiratory rhythm through a sensor, and supplying oxygen during inspiration, wherein the reliability of an electronic element is reduced in a low-temperature environment, and the response to rapid respiration is lagged; 4. The pressurizing cabin has large volume and high cost, and is only suitable for fixed places. The above technologies all have limitations of different degrees, and cannot cover various use scenes such as personal portability, sleep rest, stationary residence and the like at the same time by a simple physical pressurization mode. Disclosure of Invention Technical problem The invention aims to solve the problems that the existing plateau oxygen supply equipment depends on an external oxygen source, cannot continuously provide a proper air pressure environment and is difficult to cover the use requirements of multiple scenes, and provides a technical scheme for improving the breathing condition through physical pressurization. Technical proposal The invention provides a pressurized plateau breathing system which comprises a breathing unit, an air pump unit and an expiration unit. The breathing unit is used for accommodating the breathing part of a human body to form a closed or semi-closed space, and can be selected from the following forms: a mask or a breathing mask, which covers the mouth and nose parts and is suitable for dynamic scenes such as walking, working and the like; helmet type covering the whole head, suitable for cold environment or scene requiring head protection; sleeping bag type, which is used for accommodating the whole human body and is suitable for sleeping and resting scenes; Cabin type, including closed cab, sentry box or house, suitable for fixing residence or workplace. The pressure-bearing design of the breathing unit is that the internal pressure is kept to be 0.8-1.0 standard atmospheric pressure when the breathing unit is used, and the breathing environment of a low-altitude area is simulated. The air pump unit is communicated with the breathing unit and is used for compressing external air and then sending the compressed external air into the breathing unit. The working pressure of the air pump is 20-50 kPa (about 0.2-0.5 atm), so that the internal pressure of the breathing unit is higher than the ambient atmospheric pressure. For the mask type breathing unit, the air supply flow of the air pump is not lower than 120L/min (calculated according to 1 standard atmospheric pressure) so as to meet the minute ventilation requirement under the maximum motion state of the human body. The air pump unit can adopt various driving modes: the electric air pump is powered by a battery or an external power supply, and is suitable for portable or fixed use; the mechanical air pump is driven by an engine or manpower and is suitable for the environment without electric power; the manual air pump comprises a hand-operated or foot-operated air pump for emergency use. The expiration unit is arranged on the breathing unit and is used for exhausting the expired air and maintaining the internal pressure. According to different breathing unit forms, the expiration unit adopts differential design: for a mask-type or helmet-type breathing unit, a breathing mode of breathing by a nose nozzle is adopted: when inhaling, the gas is sent into the breathing unit through the air pump and inhaled by the nasal cavity; when in expiration, the gas
