Description

Miniature oxygenerator

Technical Field

The utility model belongs to the technical field of the oxygenerator, concretely relates to miniature oxygenerator.

Background

The molecular sieve oxygen generator is an oxygen generator which separates oxygen from air by adopting pressure swing adsorption principle, and is characterized by that the air is compressed by compressor, and the compressed air is fed into adsorption tower equipped with molecular sieve by means of scavenging valve, and the oxygen is cyclically produced by means of adsorption-desorption circulation.

The molecular sieve oxygen generation is a process of separating oxygen by changing pressure parameters according to different adsorption amounts of oxygen and nitrogen on the adsorbent under different pressures by using a zeolite molecular sieve as the adsorbent. The oxygen concentration obtained by this process can reach up to about 96%. Oxygen is an indispensable component for maintaining vital signs of human bodies, and oxygen is needed for normal operation and metabolism of various organs of human bodies. Patients with respiratory diseases, such as asthma, tracheitis, bronchitis, etc., need to inhale oxygen for a long time to relieve symptoms. Patients with arteriosclerosis, liver and lung dysfunction, coronary heart disease and cerebral apoplexy can reduce the incidence of diseases, improve the function of internal organs and enhance the immunity by regularly inhaling oxygen. By inhaling oxygen, the oxygen deficiency state can be improved, so that the content of various gases in the blood of a patient, especially the content of carbon dioxide and oxygen, can be corrected. In order to achieve the above objects, the prior art has developed various ways for oxygen therapy that can be used in the home. First, oxygen is supplied by storing oxygen in gaseous form, and gas cylinders of various sizes are used, which are cumbersome to use due to their bulkiness and present safety hazards. Second, by storing oxygen in liquefied form, for example, vaporizing its liquid to provide gaseous form to the patient or user. In the third mode, high-concentration oxygen is generated by molecular sieve adsorption, and particularly a PSA (pressure swing adsorption) oxygen generation device. The first and second methods are not suitable for home use, and the third method is that the concentration of the oxygen generating device is not high enough, or the generated oxygen is not effectively utilized, which results in waste, and the device is large in volume, needs power supply, and the demand of patients or users is more and is not bound by places. Therefore, the portable oxygen generator with small volume and strong function has strong market competitiveness.
