The present invention relates to an infant incubator, and more particularly, by supplying clean air filled with oxygen to a nursery that is provided to infants vulnerable to a polluted environment to isolate and protect the infants from an external polluted environment, thereby providing an optimal environmental condition. The present invention relates to an oxygen enriched air purifier for infants.

In general, the nursery is composed of a bed mounted on the base, the base, and a transparent hood formed of an acrylic resin and covering the bed to form a nursery room isolated from the surroundings. Air temperature and humidity in the nursery is adjusted to be the optimal conditions for the infants placed in the nursery.

However, in the case of the nursery used in the nursery of the hospital, obstetrics and gynecology, the air of the nursery is very clean, so there is no problem in purifying the air, but when using the nursery at home, tobacco smoke, pollen, smoke, bacteria And various contaminants such as dust may contaminate the air flowing into the incubator, which may seriously damage the health of the infant. Therefore, supplying clean air and oxygen to the incubator used at home is an important factor in maintaining the health of the infant.

In general, a method of generating oxygen generally includes a chemical reaction method, an electrolysis method, and a physical separation method. The chemical reaction method involves reacting metal oxides with water, hydrogen peroxide, sodium percarbonate, alcohol, and the like, or KMnO ₄ and / or KClO ₄ . Pyrolysis is a method of generating oxygen, and electrolysis is a method of separating water and water containing an electrolytic material into oxygen and hydrogen using electricity.

However, the method has the disadvantage that the structure of the device is complicated, large in size, and expensive.

On the other hand, the infant incubator for home use must remove the pollutants such as cigarette smoke, pollen, smoke, bacteria and dust contained in the air as well as the supply of oxygen, so that the pollutant can be removed in addition to the oxygen generator. It is necessary to equip additional devices such as filters, sterilizers and the like.

The present invention has been made in order to improve the above-mentioned problems, there is a technical problem to provide an oxygen enriched air cleaning nursery for infants including an air supply and a nursery to provide an air composition beneficial to the infant.

In addition, the present invention provides a process for passing contaminated air through an air purifying unit, passing the treated air through an oxygen enrichment module to produce oxygen-filled air, and introducing the oxygen-filled air into the incubator. There is.
