Technical Field

The invention relates to the field of special-purpose clothes, in particular to clothes capable of instantly and continuously preparing oxygen-enriched air for health care and outdoor activities.

Background

Along with the rapid development of the socioeconomic level of China, the living standard of people is obviously improved and promoted, so that the living mode of health care is more emphasized. The health care oxygen inhalation (oxygen therapy) gradually enters common families and community rehabilitation centers, and becomes a necessary and important life health care means. In our daily life, pregnant women, the middle-aged and elderly people, certain disease rehabilitation people in home care, mental workers, and engineering technicians working in underground or closed space for a long time are the main groups in need of health care oxygen inhalation (oxygen therapy); in addition, some people with altitude sickness also need temporary health care oxygen inhalation (oxygen therapy) when engaged in outdoor activities such as mountain climbing, highland tourism and the like. The purity of oxygen required by health-care oxygen inhalation (oxygen therapy) does not need to reach high purity (not less than 99.5%) like medical oxygen, and oxygen-enriched air with oxygen content higher than 21% is generally used, and the oxygen content is more than 22-35%. In addition, the preparation equipment is also greatly different from a large fixing device for preparing medical oxygen, and the most important difference is that the preparation of the oxygen for health care is mainly carried out by small-sized portable equipment.

However, the conventional portable oxygen generating equipment is single in product, and mainly comprises a household oxygen generator, a liquid oxygen tank, an oxygen bag and the like. The household oxygen generator can generate oxygen by electrifying without oxygen storage equipment and a fixed oxygen supply source, and has lower cost during continuous oxygen supply, but has the defects of expensive equipment price, inconvenient movement, inapplicability to outgoing activities, noise in the use process and need of regular detection and maintenance. The liquid oxygen tank is light, suitable in shape and size and convenient to carry, is suitable for oxygen supply during outdoor activities, but is high in general use cost, easy to leak and waste, only capable of continuously supplying oxygen for 6-8 hours and incapable of continuously supplying oxygen. The oxygen bag has the same problems as the liquid oxygen tank and is used for a shorter time.

In view of the above circumstances, research and development of oxygen-enriched air preparation equipment which can effectively prepare oxygen for health care, can avoid the defects of high price, inconvenient movement, incapability of continuously supplying oxygen and the like of the existing portable oxygen preparation equipment and can be used immediately has very important significance. The clothing capable of producing oxygen-enriched air for health care and outdoor activities based on molecular exchange flow phenomenon is characterized by that it can continuously separate and concentrate oxygen from air to produce oxygen-enriched air by using heat quantity dissipated by human body as driving force.
