Description

Technical Field

[0001] The utility model relates to the technical field of oxygen generation, and particularly relates to a medical molecular sieve oxygen generation device. Background Art

[0002] Medical molecular sieve oxygen generation equipment is an efficient medical device that separates oxygen from the air through pressure swing adsorption technology. This device usually consists of two adsorption towers, each filled with molecular sieve. The difference in the adsorption capacity of nitrogen and oxygen by the molecular sieve is utilized to achieve gas separation. Under pressurized conditions, impurities such as nitrogen and carbon dioxide in the air are adsorbed by the molecular sieve, while oxygen flows out through the pores of the molecular sieve to form high-purity oxygen. When an adsorption tower reaches saturation, it is regenerated through a flushing and desorption process to maintain continuous oxygen supply. However, when the existing medical molecular sieve oxygen generation equipment generates oxygen, since most of them only have a single pipe directly connected at the air inlet, the high-pressure gas entering the molecular sieve space is uneven, the air cannot fully contact the molecular sieve, and the oxygen concentration after flowing out cannot be effectively guaranteed; secondly, due to the influence of molecular sieve deformation, the oxygen concentration in the prepared product is further affected.

[0026] Specifically, in order to prevent debris in the molecular sieve 7 from entering the gas distribution disk 6, a breathable pad 9 is attached to the upper surface of the gas distribution disk 6.
