Plateau auxiliary breathing device

Abstract

The invention relates to a plateau auxiliary breathing device which comprises an air inlet pipe, an air outlet pipe, a respirator and a plurality of drivers and air pressure conversion devices, and the air pressure conversion devices can separate air in the respirator from the external environment and adjust the air pressure and the air flow in the respirator; after the air pressure conversion device is replaced by the air pump and the air discharge device, the air pump is used for increasing pressure and air, the air discharge device is used for reducing pressure and discharging air, and the air pump and the air discharge device are combined to separate the inside of the cover from the outside; increasing and decreasing of air pressure in the mask can be adjusted through an automatic controller, and the air circulation state of high air pressure in the mask during inspiration and air pressure in the mask during expiration is achieved; after the air exhaust device is replaced by the air cylinder type exhaust valve, the air pressure in the cover is stabilized near the set air pressure, the air pressure in the cover and the air pressure in the body are always the same, the cover is in a non-closed fluid state, a wearer can freely breathe pressurized air, and the plateau oxygen deficit is overcome.

Description

technical field [0001] The invention relates to a plateau auxiliary breathing device, in particular to a plateau auxiliary breathing device suitable for plateau areas. Background technique [0002] In plateau areas, the proportion of oxygen in the air is similar to that of plains, but the oxygen concentration is much lower than that of plains. This affects people's life, travel, exercise, and even diseases such as altitude sickness. The existing technology is to inhale oxygen or inhale pressurized gas. The former oxygen production process is expensive and should not be widely used for a long time; the latter inflates and pressurizes the nose and mouth, firstly it is easy to cause the nose to dry out, and secondly, in the actual use process, it will inevitably cause a certain amount of air in the breathing mask during the inhalation process.

Problems solved by technology

The former oxygen production process is expensive and should not be widely used for a long time; the latter inflates and pressurizes the nose and mouth, firstly it is easy to cause the nose to dry out, and secondly, in the actual use process, it will inevitably cause a certain amount of air in the breathing mask during the inhalation process. The degree of pressure drop (air pressure drop), the faster the inflation rate, the smaller the pressure drop; the slower the inflation rate, the greater the pressure drop. In order to avoid excessive pressure drop, the inflation rate needs to be increased. However, the air-drying problem is more serious when the airflow increases. After the inspiratory action is over, continuing to provide gas will reduce the pressure drop, resulting in a gas density in the mask that is greater than the gas density in the body

Some pressurized breathing masks are equipped with a ventilation valve to release the gas released by exhalation. However, the air pressure in the breathing mask is greater than the ambient air pressure, the ventilation valve is not opened, and the air pressure in the mask is greater than the internal air pressure, the human body cannot effectively exhale the gas , it is more difficult to increase the air pressure value in the mask, and the expected goal of increasing the air pressure in the mask to achieve the opening of the ventilation valve is difficult to achieve in practice

The intermittent ventilation valve is also difficult to distinguish the breathing state in the mask. It is difficult to realize that the air pressure in the mask is high when inhaling, and the air pressure in the mask is lower than the air pressure in the body when exhaling, or that the air pressure in the mask and the air pressure in the body are always close to the same. It is a non-closed fluid state. The above key technical problems cannot be solved, resulting in pressurized assistance that can only inhale through the nose and exhale through the mouth, which is inconsistent with the normal breathing habits of ordinary people; Causes brain hypoxia, and cannot be used in diet and unconscious sleep. Therefore, the common solution is still to use oxygen cylinders to breathe.

[0003] Ordinary airbags, which are often used in conjunction with pressurized gas, are difficult to store gas higher than ambient pressure in plateau areas. When the airbag is filled with pressurized gas, the airbag immediately expands to become an airbag with the same air pressure as the outside world. Additional airbags are required. The internal air pressure, the power required by the pressurizer will increase significantly; and when the air pressure in the air bag reaches the set air pressure, the human body inhales air from the air bag will not cause the air bag to dry up like in plain areas. Ordinary air bags are used to store pressurized gas There is no obvious effect, on the contrary, it will greatly generate supercharged energy consumption.
