Description

Portable oxygen therapy system

Technical Field

The utility model relates to the field of plateau oxygen therapy devices, in particular to a portable oxygen therapy system.

Background

Domestic and foreign researches prove that after a marching army rapidly enters a plateau area with the altitude of more than 3000m, a respiratory system, a circulation system, a blood system, an endocrine system and a central nervous system of the marching army are influenced by high altitude environmental factors such as hypoxia, low pressure, cold, dryness, strong ultraviolet rays and the like in a short time to generate a series of acute altitude disease syndromes such as headache, nausea, vomiting and the like, the symptoms are mostly generated hours or 1-3 days after the marching of the marching army enters the plateau area, and the symptoms are gradually disappeared after the plateau area is generally adapted for 3-10 days. In the plateau area, the atmospheric pressure is reduced by about 11.5 percent when the altitude is increased by 1000m, and the oxygen partial pressure is reduced, so that the fighting capacity of the army weakened by the AHAD can be reduced to the minimum by adopting timely treatment measures for the gradual plateau stationing officers and soldiers and the army personnel executing the emergency combat mission.

Low-pressure and low-oxygen are main pathogenic factors of AHAD, and plateau oxygenation implemented at present, such as an oxygen enrichment room (mostly used for night rest and oxygen supply of military personnel), a liquid oxygen storage tank (large and heavy, and inconvenient for troops to move to combat), a hyperbaric oxygen chamber (limited in space and not suitable for troops to combat), and pressurization, such as a portable pressurized air chamber (high in cost and poor in effect), and a portable plateau individual pressurized oxygen chamber (poor in tightness and difficult in control of oxygen inhalation amount) scheme can only change the oxygen uptake demand of the small environment where a stationed officer is located, and is limited in time, space and available objects. In the conventional work of prevention and treatment of AHAD (advanced health care) of officers and soldiers in plateau stationing training, an oxygenation and pressurization scheme or conventional 'static' prevention and treatment is mostly thought, but the scheme is difficult to implement in reality, and the scheme comprises the step adaptation (the step adaptation is generally accepted as the most effective strategy for improving the anoxia tolerance of a human body, namely the step adaptation is stopped for 5-10 days at the altitudes of 1000-2000 m and 3000-4000 m respectively before the officers and soldiers enter an area with the altitude of more than 5000m, so that the machine body gradually adapts to the hypoxic environment to accelerate the acclimation process of the plateau), and the special situations that armies rapidly advance to the plateau to execute combat tasks and the like are still not fully considered.

Therefore, the above conventional hyperbaric oxygen therapy device has disadvantages and drawbacks in structure and use, and further improvement is needed. How to create a system for realizing accurate oxygen supply suitable for human body needs and an oxygen therapy device which can be used in a portable manner in a plateau area becomes an urgent need of improvement in the industry at present.
