DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0026] The present invention is exemplarily illustrated by but not limited to following embodiments.

[0027] The present invention is a skin-friendly absorbent structure providing oxygen which may release oxygen after absorbing moisture with the pH remaining skin-friendly neutral, weak acidic and slightly alkaline, and the skin-friendly absorbent structure providing oxygen (1) comprises a absorbing layer (101) and skin-friendly and oxygen providing units (102) wherein the skin-friendly and oxygen providing units are evenly dispersed in the entire (FIG. 1) or partial (FIG. 2) scope of the absorbing layer; With reference to FIGS. 3, 4 and 5, the illustrated skin-friendly absorbent structure providing oxygen (1) may be disposed in personal hygienic products, such as a sanitary napkin (3), a woundplast (4) and a diaper (5), to increase the oxygen content in the subenvironment because the increased oxygen also inhibits the growth of the anaerobic bacteria.

Embodiment One

[0028] The diaper containing magnesium peroxide and lactic acid 2MgO.sub.2+2H.sub.2O.fwdarw.2Mg(OH).sub.2+O.sub.22CH.sub.3CH(OH)COOH+Mg(OH).sub.2.fwdarw.(C.sub.3H.sub.5O.sub.3).sub.2Mg+2H.sub.2O The diaper contains magnesium peroxide and lactic acid. When not in use, the diaper is dried wherein the magnesium peroxide and lactic acid are solid having no effect on the pH; When in use, the magnesium peroxide of the diaper will produce magnesium hydroxide and oxygen after absorbing the moisture of the urine, reducing the moisture but increasing the oxygen in the subenvironment of the diaper so that the growth of the anaerobic bacteria is inhibited; And when encountering the magnesium hydroxide, the lactic acid will release hydrogen ions (H.sup.+) which will neutrally react with the hydroxyl ions (OH.sup.−) of the magnesium hydroxide, transforming into magnesium lactate and water along with a little produced oxygen wherein the magnesium lactate is weak acidic, doing no harm to the skin.

Embodiment Two

[0029] The Sanitary Napkin Containing Calcium Peroxide and Citric Acid

[0030] The sanitary napkin contains 1 g calcium peroxide and 2 g citric acid. When not in use, the sanitary napkin is dried wherein the calcium peroxide and the citric acid are solid which have no effect on the pH; when in use, the calcium peroxide of the sanitary napkin absorbs the moisture of the blood, producing calcium hydroxide and oxygen. When encountering the calcium hydroxide, the citric acid will release hydrogen ions (H.sup.+) which will neutrally react with the hydroxyl ions (OH.sup.−) of the calcium hydroxide. After adding 100 ml water to 1 g calcium peroxide and 2 g citric acid of the sanitary napkin and stirring them sufficiently for 5 minutes, the pH is 4.82, being weak acidic and a little oxygen is produced; Comparing with the prior art (US20150182655) containing the pulp with 0.9% citric acid and 3% Ixper 75 C (containing 75% calcium peroxide), 100 ml water is added to 2.25 g calcium peroxide and 0.95 g citric acid in the same proportion and after stirring them sufficiently for 5 minutes, the pH is up to 12.10 and a lot of hydrogen peroxide instead of oxygen is produced with great harm to the skin.

[0031] As the oxygen producing process is slow after adding water to 1 g calcium peroxide and 2 g citric acid, catalase is further added wherein the calcium peroxide will produce calcium hydroxide and hydrogen peroxide after absorbing the moisture and when encountering the catalase (short for CAT), the hydrogen peroxide will rapidly produce oxygen while the citric acid, upon encountering the calcium hydroxide, will release hydrogen ions (H.sup.+) which will neutrally react with the hydroxyl ions (OH.sup.−) of the calcium hydroxide, the reaction formula being as follows:

##STR00001##

[0032] After adding 100 ml water to 1 g calcium peroxide, 2 g citric acid and catalase and stirring them sufficiently for 5 minutes, the oxygen is rapidly produced, inhibiting the growth of the anaerobic bacteria, and the pH of the liquid is 4.82 which is weak acidic, having no irritating effect on the skin and giving a comfortable feeling.

Embodiment Three

[0033] A woundplast able to produce oxygen with a skin-friendly pH. The absorbing layer of the woundplast contains fibers sprayed with solid lactic acid, fibers sprayed with solid oxalic acid and fibers sprayed with solid sodium peroxide. When not in use, the woundplast is dried wherein the lactic acid, the oxalic acid and the sodium peroxide are solid, having no effect on the pH.

[0034] When in use, the woundplast absorbs the moisture of the blood from the wound, producing sodium lactate, sodium oxalate and oxygen. At the moment, in the subenvironment of the woundplast, the moisture is reduced and the oxygen is increased, inhibiting the growth of the anaerobic bacteria, and the proportion of the lactic acid, the oxalic acid and the sodium peroxide may be adjusted to make the pH thereof is between 4 and 9, doing no harm to the skin, after encountering water.

Embodiment Four

[0035] A Sanitary Napkin Able to Steadily Produce Oxygen with a Skin-Friendly pH

[0036] The sanitary napkin contains calcium peroxide, oxalic acid, citric acid and catalase in the proportion of 5:2.3:6:0.05. When not in use, the sanitary napkin is dried wherein the calcium peroxide, the oxalic acid, the citric acid and the catalase are solid, having no effect on the pH; When in use, the calcium peroxide absorbs the moisture of the blood, producing calcium hydroxide and hydrogen peroxide. When encountering the catalase, the hydrogen peroxide will rapidly produce oxygen while the oxalic acid and the citric acid, upon encountering the calcium hydroxide, will release hydrogen ions (H.sup.+) which will neutrally react with the hydroxyl ions (OH.sup.−) of the calcium hydroxide. After adding 100 ml water to the calcium peroxide, the oxalic acid, the citric acid and the catalase in the proportion of 5:2.3:6:0.05 and stirring them sufficiently for 5 minutes, the oxygen is rapidly produced, inhibiting the growth of the anaerobic bacteria, and the pH of the liquid is 4.82 which is weak acidic, having no irritating effect on the skin and giving a comfortable feeling.

[0037] Different metal peroxides may be used for matching with different solid acids wherein the metal peroxides comprise magnesium peroxide, calcium peroxide, sodium peroxide and potassium peroxide and the solid acids comprise citric acid, lactic acid, calcium lactate, oxalic acid, hydrochloric acid, phytic acid and silicic acid. The metal peroxides and the solid acids are matched in different proportions and after adding water, if the pH is 4 to 9, it has no irritating effect on the skin and if the pH is 4 to 5.5, it may make the skin feel comfortable.

Embodiment Five

[0038] Oxygen Providing Paster Unit

[0039] The materials of the absorbing layer contain non-woven fabrics, gauzes and the like water absorbing materials. Solid oxides, solid acids and catalase are mixed evenly and then sprayed on the absorbing layer to form the oxygen providing paster unit. The oxygen providing paster unit may be attached to the parts of the body that needs to be provided with oxygen, such as the wound.

[0040] In addition to direct use of the oxygen providing paster unit, the wound may also be dressed firstly with a woundplast and then the oxygen providing paster unit is used to cover the woundplast. At the moment, the moisture produced by the wound will be released to the oxygen providing paster unit through the woundplast and the oxygen produced by the oxygen providing paster unit reaches the wound through the woundplast At this moment, in the subenvironment of the oxygen providing paster unit outside of the wound, oxygen is greatly increased and the skin-friendly pH is maintained.
