Breathing self-adaptive portable oxygen generator

Abstract

The invention discloses a breathing self-adaptive portable oxygen generator. The oxygen generator comprises a device shell and a support plate arranged at the bottom of the device shell; caster wheelsare arranged at corner positions of the bottom of the support plate; a damping mechanism is arranged between each caster wheel and the support plate; a handle is arranged at the top of the device shell; and an oxygen generator main body, an oxygen temporary storage box and an oxygen leading-out cylinder are fixedly arranged in the device shell from bottom to top in sequence. The device has the advantages that the structure is simple, the design is ingenious, the oxygen inhalation amount during breathing can be accurately controlled to prevent the phenomenon of excessive oxygen inhalation, self-adaptive and more accurate control of the oxygen inhalation amount of people can be ensured, and safety is high. Through arrangement of elastic cross cranks and elastic damping pieces, the effects of damping, energy absorbing, energy releasing and energy dissipating can be achieved, so that influence of excessive vibration on the whole device in a moving process can be reduced, and the service life of the whole device can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a breath-adaptive portable oxygen concentrator. Background technique [0002] Oxygen concentrators, there are many kinds of oxygen concentrators for breathing on the market. Due to the different principles of oxygen production, the use characteristics of each oxygen concentrator are also different. Oxygen production mechanism oxygen principles include: molecular sieve principle, polymer oxygen-enriched membrane principle, electrolysis water principle and chemical reaction oxygen production principle. For example, the working principle of molecular sieve oxygen generator: use molecular sieve physical adsorption and desorption technology. The oxygen concentrator is filled with molecular sieves, which can absorb nitrogen in the air when pressurized, and the remaining unabsorbed oxygen is collected and purified to become high-purity oxygen. The molecular sieve discharges th...

Problems solved by technology

[0004] However, most of the above are caused by excessive oxygen inhalation caused by the inability to perform adaptive breathing according to the patient's individual characteristics; and although most of the existing oxygen generating devices are equipped with casters to make the movement convenient, the device is also vulnerable to collisions or other factors during movement. Large vibrations will seriously affect the service life of the entire device
