Abstract
A skin-friendly absorbent structure providing oxygen, comprising a absorbing layer and skin-friendly and oxygen-providing urits, the skin-friendly and oxygen-providing unit being evenly dispersed in partial or entire scope of the absorbing layer wherein the skin-friendly and oxygen-providing unit comprises oxygen providing units and pH regulating units; and the pH of the skin-friendly absorbent structure is between 4 and 7 after absorbing liquids.
Description
A Skin-friendly Absorbent Structure for Providing Oxygen BACKGROUND OF THE INVENTION
1. Field of the invention The present invention relates to a skin-friendly absorbent structure for providing oxygen which may be disposed in personal hygiene products and release oxygen after absorbing liquids with the pH remaining skin-friendlily neutral, weak acidic and slightly alkaline, thereby having no irritating effect on the skin.
1. Field of the invention The present invention relates to a skin-friendly absorbent structure for providing oxygen which may be disposed in personal hygiene products and release oxygen after absorbing liquids with the pH remaining skin-friendlily neutral, weak acidic and slightly alkaline, thereby having no irritating effect on the skin.
2. Description of the prior art There are various personal hygiene products contacting the body surface, such as sanitary napkins, diapers, cloth diapers, pasties, insoles, disposable underwear and oxygen providing paster units on the market. Most of these hygiene products emphasize the structural features of each layer as well as the comfort and convenience to wear thereof, but what is the most important is how to maintain human health when wearing them.
Women will use sanitary napkins and tampons during the menstrual cycle, both of infants and children need to use diapers or cloth diapers before they can control to go to the bathroom, and the old and the people with difficulty in moving also choose and use adult diapers. The major components of sanitary napkins, tampons, diapers, cloth diapers or adult diapers are water absorbing materials, cotton, non-woven fabrics or polymeric fibers and they will entirely or partially cover the lower part of the body when in use.
When wearing sanitary napkins, diapers and cloth diapers, the wearer usually feels comfortable at the beginning except for poor material softness, contained inferior raw materials or fluorescent materials resulting in allergy. However, after wearing for a period of time and with the entry of blood, urine and sweat, the wearer will have an uncomfortable feeling, such as of stuffiness and wetness because the leak proof design and the closeness to the skin of the sanitary napkin, diaperand cloth diaper form a subenvironment that is near to be enclosed.
In the enclosed subenvironment formed by wearing sanitary napkins, diapers and cloth diapers, the increased humidity due to the absorption of body fluids, such as .. blood, urine and sweat, and the increased body temperature because of the upper body surface relative to the enclosed environment give rise to stuffiness and discomfort. Furthermore, personal hygiene products are not designed aseptically and all of the ambient environment, the body surface and the body fluids are likely to contain bacteria, molds and fungus. The proteins, carbohydrates and salinity of .. the body fluids may be used as the nutrition source of microorganisms, causing the reproduction of molds and fungus in such a high-temperature, high-humidity and high- nutrition environment. Failure to change them in time may result in infection.
Therefore, a concern for the public is how to safely and conveniently provide oxygen in the semi-enclosed subenvironment of personal hygiene products, such as sanitary napkins, diapers and cloth diapers, and the like.
In prior art, peroxides are used as the solid oxidizer to produce transportable oxygen. A Japanese patent (WA 2004536010) discloses a chemical oxygen generator wherein alkaline-earth metals (LiC104, LiC103, NaC104, NaC103, KC104 and KC103)permddes (Na202 and K202)and superoxides (K02 and Na02)are used to produce oxygen; A Taiwan patent (application number: 083206076) discloses a mask with oxygen regenerating tank wherein sodium peroxide is used to produce oxygen.

SUMMARY OF THE INVENTION
In view of the problems of stuffiness and bacteria breeding when using the sanitary napkins and diapers on the market and the harm to the skin due to the strong alkalinity if solid oxidizer is added, the present invention, after a long-time design and research by the inventor, provides a skin-friendly and oxygen providing structure which may be disposed in personal hygiene products and release oxygen after absorbing liquids with the pH remaining skin-friendlily
Women will use sanitary napkins and tampons during the menstrual cycle, both of infants and children need to use diapers or cloth diapers before they can control to go to the bathroom, and the old and the people with difficulty in moving also choose and use adult diapers. The major components of sanitary napkins, tampons, diapers, cloth diapers or adult diapers are water absorbing materials, cotton, non-woven fabrics or polymeric fibers and they will entirely or partially cover the lower part of the body when in use.
When wearing sanitary napkins, diapers and cloth diapers, the wearer usually feels comfortable at the beginning except for poor material softness, contained inferior raw materials or fluorescent materials resulting in allergy. However, after wearing for a period of time and with the entry of blood, urine and sweat, the wearer will have an uncomfortable feeling, such as of stuffiness and wetness because the leak proof design and the closeness to the skin of the sanitary napkin, diaperand cloth diaper form a subenvironment that is near to be enclosed.
In the enclosed subenvironment formed by wearing sanitary napkins, diapers and cloth diapers, the increased humidity due to the absorption of body fluids, such as .. blood, urine and sweat, and the increased body temperature because of the upper body surface relative to the enclosed environment give rise to stuffiness and discomfort. Furthermore, personal hygiene products are not designed aseptically and all of the ambient environment, the body surface and the body fluids are likely to contain bacteria, molds and fungus. The proteins, carbohydrates and salinity of .. the body fluids may be used as the nutrition source of microorganisms, causing the reproduction of molds and fungus in such a high-temperature, high-humidity and high- nutrition environment. Failure to change them in time may result in infection.
Therefore, a concern for the public is how to safely and conveniently provide oxygen in the semi-enclosed subenvironment of personal hygiene products, such as sanitary napkins, diapers and cloth diapers, and the like.
In prior art, peroxides are used as the solid oxidizer to produce transportable oxygen. A Japanese patent (WA 2004536010) discloses a chemical oxygen generator wherein alkaline-earth metals (LiC104, LiC103, NaC104, NaC103, KC104 and KC103)permddes (Na202 and K202)and superoxides (K02 and Na02)are used to produce oxygen; A Taiwan patent (application number: 083206076) discloses a mask with oxygen regenerating tank wherein sodium peroxide is used to produce oxygen.
