Description:
MULTI-FUNCTIONAL MENSTRUAL PAD INCLUDING BIOCERAMIC SUBSTANCES AND METHOD FOR THE SAME Technical Field The present invention relates to a multi-functional menstrual pad including bioceramic substances and a method for the same. More particularly, it relates to a multi-functional menstrual pad including bioceramic substances and a method for the same, which implant bioceramics (comprised of a mixture of oxide fine particles, i. e., SiO, 45-90 weights (%), Al2O3 0.5-30.1 weights (%), Fe203 0.5-30.1 weights (%), Fe 0.5-30.1 weights (%), and TiO2 0. 1~10 weights (%), that are a main component of a clay mineral being fine ceramics mixture), simultaneously adjust a dysmenorrhea, a bad smell, and a bacteria growth, and ensure a woman's normal social activity even in her dysmenorrhea (i. e., a menstrual cramp pain) period without an additional trouble factor.

Background Art Scientifically, a dysmenorrhea (i. e, a menstrual cramp pain) has been frequently handled by a gynecologist, and means a painful menstruation.

According to statistics, the most women of about 60-90% experience a dysmenorrhea in every month. This fact brings about a shortage (about 6-10 hundred million) of female labor productivity.

There are two kinds of dysmenorrheas, that is, a primary dysmenorrhea having no lesion, and a secondary dysmenorrhea accompanied with the lesion.

Since the secondary dysmenorrhea is accompanied with the lesion, woman having the secondary dysmenorrhea should receive a medial treatment in a gynecological service part in hospital.

The primary dysmenorrhea is a cramp pain that periodically occurs in the most women every month and is generated in the vicinity of a hypogastrium and

a upper pubis. The primary dysmenorrhea may be transmitted to a lower abdominal region and a lower crural part. A few women undergo an extreme pain.

According to a concrete example about another symptom except the above cramp pain, women of about 50% undergo a plurality of constitutional symptoms (i. e., a lower backache 60%, a vomiting 89%, a fatigue 85%, dizziness and diarrhea 60%, anorexia and headache 45%, oversensitiveness, a sense of unease, etc.) along with the cramp pain. Besides, various bacteria over 20 kinds, such as a colon bacillus, a pseudomonas, trichomonas, etc., are grown in the most women's body, and occur an unpleasant smell.

Such a primary dysmenorrhea occurs before a menstrual cramp pain or occurs within a few hours on that day generating the menstrual cramp pain, continues for one or two days, and typically does not exceed three days over.

According to the actual facts disclosed until now, a large quantity of prostagladins secreted in a menstrual blood causes an irregular and abnormal uterine contraction as well as irregular and abnormal imbalance of uterus. The irregular and abnormal uterine contraction/imbalance cuts off an oxygenation of a muscle tissue inside of the uterus, and occurs an ischmia. In conclusion, it is well known that the irregular and abnormal uterine contraction/imbalance and the ischmia bring about the primary dysmenorrhea.

To overcome a dysmenorrhea and a symptom accompanied with the dysmenorrhea, a method of warming body temperature like hot bath has been typically used. However, the conventional menstrual pad has a simple function for just sanitarily treatment of a menstrual blood during a menstruation period, cannot reduce the dysmenorrhea.

Accordingly, another conventional method for reducing the dysmenorrhea has used another medical treatment or a native secondary medical treatment that is disclosed in the following.

That is, a first conventional medical treatment mostly employs medications that allows a patient to take NSAID (Non-Steroidal Anti-Inflammatory Drugs) according to a medical prescription of a doctor. A second medical treatment is a thermal care for warming a hypogastrium, particularly a female

belly. For the thermal care, a heating pad or a bathing in a hot water has been mainly used. Besides, as another medical treatment before the menstrual period or during the menstrual period, a sport method such as a jogging or aerobic exercises for warming up the whole female body has been used.

In addition, a few women use an oriental medicine acupuncture, take a fish oil (i. e., omega-3 fatty acids), or drink an oriental medicine tea. Some women wear a hard magnetic material on their waist, or insert a manufactured product for emitting a heat by a battery into a vagina.

However, the aforementioned methods have the following disadvantages.

The first medical treatment is accompanied with a harmful secondary effect such as a gastrointestinal injury and a dizziness and the like. Although the second medical treatment has a considerable theoretical basis in the light of an excessive muscle contraction. the second medical treatment causes a time cost problem, a production cost problem, and a user inconvenience. Other methods except the first and second medical treatments also cause a time cost problem, a user inconvenience as well as an expensive medical treatment cost.

In the meantime, a charcoal, a mugwort, a poroligenous liquor, and a aromatic can be employed to remove a bad smell simultaneously with preventing a bacteria breeding on a menstrual pad. But, they cause a color variation and an untruthful curative effect. As a result, the treatment method using them is not employed any more for a commercial scale.

Disclosure of the Invention Accordingly, the present invention is directed to a multi-functional menstrual pad including bioceramic substances and a method for the same that substantially obviate one or more of the problems due to limitations and disadvantages of the prior art.

It is an object of the present invention to provide a multi-functional menstrual pad including bioceramic substances which implants bioceramics (comprised of a mixture of oxide fine particles, i. e., SiO2 45-90 weights (%),

A1, 03 0.5-30.1 weights (%), Fe 0.5-30.1 weights (%), Fe304 0.5-30.1 weights (%), and TiO, 0.1-10 weights (%), that are a main component of a clay mineral being fine ceramics mixture), simultaneously adjusts a dysmenorrhea, a bad smell, and a bacteria growth, and ensures a woman's normal social activity even in her dysmenorrhea (i. e., Mensturual cramp pain) period without an additional trouble factor.

It is another object of the present invention to provide a method for making a multi-functional menstrual pad including bioceramic substances.

To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described, in a multi-functional menstrual pad including: a menstruation absorption surface; an absorbent core positioned under the menstruation absorption surface, for absorbing a menstrual blood; a poly backsheet for supporting the absorbent core; a pulp fluff; an absorption substance sheet made of an absorption substance, a multi-functional menstrual pad includes a bioceramic substance comprised of SiO2 45-90 weights (%), AI, 0. 5-30. 1 weights (%), Fe 0.5-30.1 weights (%), Fe 0.5-30.1 weights (%), and TiO 0.1-10 weights (%), in the pulp fluff.

Additional features and advantages of the invention will be set forth in the description which follows, and in part will be apparent from the description, or may be learned by practice of the invention. The objectives and other advantages of the invention will be realized and attained by the scheme particularly pointed out in the written description and claims hereof as well as the appended drawings.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.

Brief Description of the Drawings The preferred embodiment of the present invention will be described more specifically with reference to the attached drawings, wherein: FIG. 1 schematically depicts an exploded perspective view of a common

structure between a general menstrual pad and the inventive menstrual pad; FIG. 2 is a cross-sectional view of a common structure between a general menstrual pad and the inventive menstrual pad; FIG. 3 is a gas density curve with the lapse of time in regard of a bioceramic substance according to the present invention; FIG. 4A depicts an emission power of far infrared rays in regard of a bioceramic substance according to the present invention; FIG. 4B depicts an emissivity of far infrared rays in regard of a bioceramic substance according to the present invention; FIG. 5 illustrates an anti-fungal experiment in regard of a bioceramic substance according to the present invention; FIGS. 6A and 6B illustrate an antibacterial experiment by a colon bacillus in regard of a bioceramic substance according to the present invention; FIGS. 7A and 7B illustrate an antibacterial experiment by a pseudomonas in regard of a bioceramic substance according to the present invention; and FIGS. 8A and 8B illustrate a dysmenorrhea alleviation effect of an experimental group and a control group in regard of a bioceramic substance according to the present invention.

Best Mode for Carrying Out the Invention Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

Hereinafter, a bioceramic substance, a menstrual pad including the bioceramic substance, and a method for making the menstrual pad will be described below.

The bioceramic substance is comprised of a mixture of oxide fine particles such as SiO,, A1203, Fe203, Fe304, and TiO,, that are a main component of a clay mineral being fine ceramics mixture.

Among the oxide fine particles, SiO2 is about 45-90 weights (%). If the

SiO, is below 45 weights (%) or is over 90 weights (%), a dysmenorrhea alleviation effect, a bad smell removal effect, and an antibacterial effect appear very little. In particular, the dysmenorrhea alleviation effect completely disappears.

In addition, A1203 is about 0.1-30.1 weights (%), Fe203 is about 0.1-30.1 weights (%), Fe304 is about 0.1-30.1 weights (%), and TiO2 is about 0.1-10 weights (%). If these oxide fine particles except Si02 are over a upper limit value or below a lower limit value, a dysmenorrhea alleviation effect, a bad smell removal effect, and an antibacterial effect appear very little.

Hereinafter, the inventive menstrual pad including a bioceramic substance and a method for making the same will be discussed in detail as compared to a general menstrual pad.

FIG. 1 schematically depicts an exploded perspective view of a common structure between a general menstrual pad and the inventive menstrual pad, and FIG. 2 is a cross-sectional view of a common structure between a general menstrual pad and the inventive menstrual pad.

As shown in FIGS. 1 and 2, a menstrual pad includes a menstruation absorption surface 1 called a dry mesh cover or a perforated film, an absorbent core B for absorbing a menstrual blood positioned under the menstruation absorption surface, and a poly backsheet 7 for supporting the absorbent core B.

The absorbent core B is manufactured by a specific fabrication process of each manufacturing company. The pulp fluff 4 is attached on an absorption substance sheet 5 as of an absorption substance, or an absorption substance is scattered on a center part of the pulp fluff 4.

A super absorption polymer is mostly used as the absorption substance.

But, on behalf of the super absorption polymer, a corn starch or a cellulose may be employed with the super absorption polymer or may be employed independent of the super absorption polymer.

In the meantime, a reference number 2 is a pulp tissue, a reference number 3 is an adhesive agent, a reference number 6 is a lycra type leg elastics, and a reference number 8 is a silicon release paper.

The inventive construction of the present invention will now be discussed

on the above constructions.

That is, although the inventive menstrual pad is similar to the above general menstrual pad including the absorption substance, the inventive menstrual pad further includes a bioceramic substance for alleviating a dysmenorrhea (i. e., a menstrual cramp pain). The inventive menstrual pad may be a pad-type menstrual pad or a panty liner type menstrual pad. A constructional difference according to an addition method of a bioceramic substance will be disclosed in the following.

Based on the constructional difference between the general menstrual pad and the inventive menstrual pad, a method for making the inventive menstrual pad will be described as compared with a conventional method for making the general menstrual pad.

The conventional method for making the general menstrual pad is as follows. A porous menstruation absorption surface 1 or a poly backsheet 7 is manufactured. A pulp fluff 4 is positioned on the poly backsheet 7 or is positioned under the menstruation absorption surface 1. An absorption substance is scattered on the pulp fluff 4, or the pulp fluff 4 is attached on an absorption substance sheet 5 as of an absorption substance. Along with the pulp fluff 4 and the absorption substance sheet 5 as of absorption substance, an absorbent core B for absorbing a menstrual blood is provided.

A method for making the inventive menstrual pad has the following characteristics. A foreign material harmful to a human body should be removed from the inventive bioceramic substances. After removing the foreign material, a step for grinding the bioceramic material to fine particles.

After the grinding step, an addition method of a bioceramic substance for alleviating the dysmenorrhea can be implemented by the following various methods.

First, a bioceramics substance sheet made of a bioceramic substance is additionally made, and is attached on the pulp fluff 4.

Second, a bioceramic substance is scattered on the center part of the pulp fluff 4.

Third, a bioceramic substance is precompounded, and is then added to an

absorption substance. After the precompounding process, the bioceramic substance may be a granular type, a pelleting type, or a powder type.

Hereinafter, a dysmenorrhea alleviation effect, a bad smell removal effect, and an antibacterial effect appear of the inventive menstrual pad will be described in detail.

First, a fundamental principle of the dysmenorrhea alleviation effect is that various kinds of treatments (i. e., a magnetic effect, a thermal care, a resonance effect, a regulation of a pain transfer substance, and a blood circulation improvement) for solving an uterine ischemia state are respectively operated or make a mutual chained reaction, thereby preventing a menstrual cramp within a short time.

Second, the bad smell removal effect employs an absorption reaction by an ion exchange reaction. It is well known that various bacteria over 20 kinds, such as a colon bacillus, a pseudomonas, trichomonas, etc., are grown in a genital organ of the most women. A material of inducing a bad smell during a menstruation period is bacteria such as an ammonia, trimethylamine, a hydrogen sulfide, a mercaptane, and amine, and is cationic particles having a strong electric characteristic. Specifically, the material of inducing the bad smell may bring about an unpleasant feeling to other peoples in vicinity of women in summer. Oxide fine particles for preventing the bad smell have a negative charge and air holes of 30 w 60 , t m in diameter, are a particle powder state, thereby causing a very large specific surface. Accordingly, the oxide fine particles has a large surface area (i. e., inner and outer surfaces) per a unit volume, which is larger than a geometric area in appearance. In the light of a chemical view, SiO2 or A1203 is coupled to °2, thereby generating a surface polarity by either a weak Van der Waals'force or a dipolar interaction. Since a force inducing another kinds of particles induce in this surface is very strong, an absorption phenomenon occurs when the surface is contacted with a bad smell inducing material being an ionic particle.

That is, electrons are moved between the oxide surface and a bad smell inducing gas, thereby generating an interaction caused by ions or an absorption caused by an electron sharing. Also, the electrons are contacted with a menstrual

blood so as to generate both an oxide surface compound and an absorption fixed in a lattice structure, thereby alleviating a bad smell.

This fact can be readily seen from tables 1 and 2 and FIG. 3 illustrating a gas density curve with the lapse of time. The table 1 illustrates a negative ion measuring table about bioceramic substances. The table 2 illustrates a deodorization test table about bioceramic substances.

Third, an antibacterial effect is caused by a high negative ion and far infrared rays of a bioceramic substance. This fact can be readily seen from table 3 and FIGS. 4a and 4b respectively illustrating an emission energy of far infrared rays and an emissivity of far infrared rays in regard of a bioceramic substance.

Hereinafter, three effects (i. e., a primary dysmenorrhea regulation function, a deodorization function, and an antibacterial effect) of the inventive menstrual pad including bioceramic substances will be described in detail with reference to the attached drawings.

By using a prototype sample, the following clinical trial shown in Table 6 is performed, thereby obtaining a very superior result.

Where, A group is 10s (i. e., teenager), B group is 20s in age, C group is 30s in age, and D group is 40s in age.

Observation opinion: (j) Three women in 60 women felt a body temperature rising effect in the vicinity of a lower abdomen, but they continuously felt a menstrual cramp pain.

(2) After using the inventive menstrual pad, the most women excepting the three women felt a dysmenorrhea alleviation effect.

B. Test II 20 women excepting the three women who continuously felt a menstrual cramp pain were selected at random, during November-December in 1999, in order to observe a placebo effect. Accordingly, the test operator told them a falsehood that they were wearing the inventive menstrual pad not a general conventional menstrual pad.

Observation opinion: (The most women told the test operator a high satisfaction state of an average score 91 (2) Women of 30s-40s in age felt a more high satisfaction state.

Preferred embodiment 2 Secondary clinical demonstration (Daeku Catholic University Medical College obstetrics/gynecology part) 1) The test method In order to verify the effects of the inventive menstrual pad, KunYang University Medical College Preventive Medicine Part and KaeMyung University Medical College Preventive Medicine Part have designed the following clinical demonstration. A random clinical test using an open or blind test was applied to some women who always felt a menstrual cramp pain during a menstrual period.

As a result, for this random clinical test, the women have used the inventive menstrual pad serving as an experimental group together with the general menstrual pad serving as a control group, under the condition that the women did not hear the effects of the inventive menstrual pad.

In addition, the most women feel that a weak symptom (e. g., a feeling of cold lower abdomen and an unpleasant feeling of lower abdomen, etc) not written on the questioning paper is alleviated. A few women show a reduction of a menstrual blood quantity as well as a reduction of a menstruation period. Such a dysmenorrhea alleviation effect of the experimental group compared to the control group in regard to VNRS and VRS is shown in FIGS. 8A and 8B.
