Description

Functional sanitary napkin

The present invention relates to a functional sanitary napkin, and more particularly, to a functional sanitary napkin having antibacterial, anti-inflammatory and anti-allergic properties, which can prevent infection, skin irritation, and eczema by pathogens.

The endometrium of a woman of childbearing age is periodically proliferated by hormones to prepare for implantation of the embryo. If the pregnancy does not occur, the endometrium is spontaneously dropped and this phenomenon is called menstruation or menstruation. Fertility refers to the period during which the egg can ovulate and become pregnant. It refers to the period from the beginning of menarche to menopause. The average menopause age is about 13 years old and the average menopause age is about 50 years old. Menstrual cycles can be divided into follicular and luteal phases, and ovulation occurs during the transition from follicular phases to luteal phases. In the follicle, the secretion of female hormone (estrogen) increases in the ovary, which stops menstruation and the lining of the uterus proliferates and begins to thicken. At the same time, when the egg matures in one ovary and the menstrual cycle is 28 days, ovulation occurs about 14 days before the start of menstruation. After ovulation, luteal hormone (progesterone) secretion increases in the ovaries, which helps prepare for endometrial implantation. If you are not pregnant, the endometrium will fall off on day 28. Normal menstrual cycles are usually between 21 and 35 days (28 days on average), lasting 3 to 7 days at intervals between the start of two consecutive menstruation periods. Looks normal.

The sanitary napkin is used to prevent leakage of menstrual blood and secretion during the menstrual period, as shown in Figure 1, the sanitary napkin is generally to prevent the leakage of the internal sheet 100, such as menstrual blood, and menstrual blood In order to have the outer sheet 300 and the absorbent member 200 positioned between the inner sheet 100 and the outer sheet 300 to absorb the menstrual blood, etc., and to absorb the menstrual blood. The outer sheet 300 may be provided with an adhesive means such as an adhesive material.

However, sanitary napkins may cause skin irritation, skin eczema, and skin irritation due to secretions such as menstrual blood, and during menstruation, mental and physical resistance is weakened. Therefore, human infections such as skin infections and vaginal infections are caused by bacterial growth such as pathogens. May cause problems.

The present invention confirms that lactic acid bacteria cultures such as Lactobacillus plantarum nF1 disclosed in Korean Patent Registration No. 10-1583018 and Korean Patent Application Publication No. 2014-0140387 have anti-allergic and anti-inflammatory activity as well as antibacterial activity. A functional sanitary napkin is disclosed that can prevent human infection by bacteria such as pathogens and prevent skin irritation.

An object of the present invention is to provide a functional sanitary napkin that can prevent infection and skin irritation caused by pathogens.

Other and specific objects of the present invention will be presented below.

The functional sanitary napkin of the present invention comprises (i) an inner sheet and an outer sheet, and (ii) an absorbent member interposed therebetween, wherein the inner sheet and / or absorbent member is Lactobacillus plantarum. It is characterized by impregnating a lactic acid bacteria culture such as nF1 or a solution containing the same.

By having such a structure, that is, lactic acid bacteria culture such as Lactobacillus plantarum nF1 is impregnated into the inner sheet and / or absorbent member, the functional sanitary napkin of the present invention exhibits anti-inflammatory, anti-allergic, as well as antibacterial, Due to such antimicrobial properties, it has the effect of preventing human infection from bacteria such as pathogens, and also has the effect of preventing skin irritation, skin eczema, and skin inflammation caused by secretions such as menstrual blood.

As can be seen in the experimental example below, lactic acid bacteria cultures such as Lactobacillus plantarum nF1, Bacillus subtilis , Staphylococcus aureus (except for some microorganisms of some cultures) Staphylococcus aureus ), Staphylococcus mutans ( Strptococcus) mutans ), Escherichia coli ) and Gardnerella vaginalis , which have an overall antimicrobial activity and produce nitric oxide (NO) in macrophages, a major cell in the inflammatory response stimulated with the inflammatory substance lipopolysacharide (LPS). In addition to showing inhibitory activity, it exhibits degranulation inhibitory activity in the rat cell line RBL-2H3 (rat basophilic leukemia), which is a major cell of the allergic reaction, activated with IgE and antigen (DNP-BSA), which are initiating factors of the allergic reaction.

The gardnerella pannalis is an anaerobic bacterium known as a major causative agent of bacterial vaginosis found in more than 98% of women with bacterial vaginosis (Korean Journal of Obstetrics and Gynecology 36 (6): 837-46, 1993). Bacterial vaginosis caused by is caused to increase the pH in the vagina to 5.0 or more, exhibits peculiar odors, pruritus and other symptoms, and is characterized by increased vaginal discharge (Am J Obstet Gynecol. 158 (4): 819-). 28, 1988).

In addition, NO, which is excessively produced by iNOS (induced NOS) during the inflammatory reaction, reacts with superoxide to form peroxynitrite, which acts as a powerful oxidant and damages cells, thereby causing inflammation and cancer. Has been reported to be involved in a variety of pathological processes including (Gupta SC et al., Exp Biol Med., 236: 658-671, 2011; Riehemann et al., FEBS Lett., 442: 89-94, 1999; Stame et al. , Science, 258: 1898-1902, 1992), substances that inhibit NO production have been proposed as anti-inflammatory candidates (Karin M. et al., Cold Spring Harb Perspect Biol., 1, pp 1-14, 2009) . In addition, mast cells, which are the major mediators of allergic reactions, contain beta-hexosaminidase in addition to histamine, and beta-hexosaminidase is released together with histamine when mast cells degranulate. Beta-hexosaminidase is known as an indicator for assessing degranulation inhibitory activity, antihistamine activity and anti-allergic activity of mast cells (Immunol., 123: 1445-1450, 1970); J Korean Soc Appl Biol Chem. 48 (4): 315-321, 2005).

Therefore, the experimental example below shows that lactic acid bacteria cultures such as Lactobacillus plantarum nF1 prevent bacterial vaginosis caused by infections such as Gardnerella pannalis through antibacterial activity, anti-inflammatory activity and anti-allergic activity. It can be said that it can alleviate skin inflammation.

In the present invention, the antibacterial sanitary napkin is largely composed of an inner sheet 100 and an outer sheet 300 and an absorbing member 200 disposed therebetween.

The inner sheet 100 has a material and structure through which secretion, such as menstrual blood, can pass, and may be specifically composed of one or more layers of fabrics or nonwoven fabrics. The fibers constituting the woven or nonwoven fabric can be used both synthetic fibers and natural fibers without particular limitation, if synthetic fibers, nylon, polyvinyl alcohol (PVA) fibers, polyester fibers, polyacrylic fibers, polyamide fibers, polyurethane Fibers, polyacrylonitrile fibers, polypropylene fibers, polyethylene fibers and the like can all be used without limitation, and if natural fibers, cotton fibers, seed fibers such as Coier, leaf vein fibers such as manila hemp and sisal hemp, flax , Bast fibers such as ramie grass, hemp, wool fibers such as wool, goat wool, silk fibers such as gaze dog, and night sleep dog can be used without limitation. Preferably, in order to minimize the irritation to the human body when using a fabric made of natural fibers, such as cotton fabrics.

The inner sheet 100 is a member in contact with the human body may be caused skin irritation, skin eczema, skin inflammation, etc. by secretions such as menstrual blood absorbed in the inner sheet 100 or penetrating the inner sheet 100, including pathogens Since various bacteria can proliferate, in order to prevent such skin irritation and suppress the growth of various bacteria, Lactobacillus has been confirmed antimicrobial activity, anti-inflammatory activity, anti-allergic activity, etc., as confirmed in the experimental example below Lactobacillus cultures such as plantarum nF1, its extracts, its concentrates, its dilutions, or its suspensions or solutions using a dispersion medium or a solvent as water or ethanol are impregnated into the inner sheet 100 for antibacterial function, You can have anti-inflammatory activity, anti-allergy, etc.

At this time, the impregnation may be made by immersing the inner sheet 100 in a diluent of a lactic acid bacterium culture such as Lactobacillus plantarum nF1 at room temperature, preferably for at least 12 hours, more preferably at least 24 hours. After soaking, the lactic acid bacteria cultures such as Lactobacillus plantarum nF1, which are impregnated, are stabilized and hot air dried at a temperature ranging from 40 ° C. to 50 ° C., for example, to remove solvents that may cause irritation or toxicity to the skin. It may be desirable to.

Meanwhile, various natural materials have been proposed in the art to alleviate skin irritation. Such natural materials include plant extracts having anti-inflammatory activity, anti-allergic activity, or both, specifically, Styrax japonica extract, Chloranthus japonicus ) extract, Podocarpus macrophyllus extract, Distylium racemosom extract, Rhododendron mucronulatum , Empetrum nigrum extract, Marsilea quadrifolia extract, Potentilla discolor extract, Gleichenia japonica extract, Cimicifuga acerina extract, Citrus sunki rind extract, Sceptridium ternatum extract and Korthalsella japonica extract are among such plant extracts. When impregnating these natural materials with lactic acid bacteria cultures such as Lactobacillus plantarum nF1 to the inner sheet 100, or impregnated alone, imparting skin irritation, skin trouble relieving effect, or enhancing or enhancing such effects. Can be designed.

When the extract is impregnated, endothelial sheet by immersing the endothelial sheet 100 in these natural product extracts at a constant time, such as 12 hours or 24 hours or more at room temperature, using an extract in the extract state with or without filtration. Functionality such as skin irritation relief can be imparted to (100). In addition to water and ethanol, the extraction solvent which may have skin irritation may be a solvent remaining in the endothelial sheet 100 when impregnated, and the residual solvent may cause skin irritation, so that the impregnated inner sheet 100 may be hot air dried. Drying is carried out in a manner known in the art to remove residual solvents, or when using an extract obtained with an extraction solvent other than water and ethanol, it is concentrated in the art after extraction, freeze drying, vacuum drying, hot air drying, spray drying, etc. It is also possible to avoid the skin irritation problem caused by the extraction solvent by removing the extraction solvent in a manner known in the present invention to obtain a powdered extract and dissolving the powdered extract in water or ethanol, especially ethanol.

In the functional sanitary napkin of the present invention, the absorbent member 200 is to absorb secretions such as menstrual blood, so that the absorbency and water retention should be excellent, so that the absorbent member 200 may consider cotton fiber or wool, goat's wool, etc. It can be made of the hair wool fiber, etc. in the form of cotton and the composition of the nonwoven fabric and the like. Preferably, the content may be a polymer absorbent such as sodium polyacrylate, which has been conventionally used in sanitary napkins. Sodium polyacrylate is a material known in the art to have an absorption ability to absorb about 200 times its weight.

Since the absorbing member 200 is a member for absorbing secretions such as menstrual blood, bacteria such as pathogens may proliferate. Therefore, in order to suppress this, it is preferable to impregnate the culture of lactic acid bacteria such as Lactobacillus plantarum nF1, such as the antibacterial activity is confirmed, such as the inner sheet 100 to have an antibacterial function.

In the functional sanitary napkin of the present invention, the outer sheet 300 is located on the outside of the absorbent member 200. Since the outer sheet 300 is a member in contact with the underwear without touching the skin, it should be able to prevent the leakage of secretion such as menstrual blood. It is made of a waterproof material such as polyethylene film. In addition, the outer surface of the outer sheet 300 can be attached to and fixed to the underwear by forming an adhesive member with an adhesive and release paper.

In the functional sanitary napkin of the present invention, the adsorption member 200 is finally placed between the inner sheet 100 and the outer sheet 300, and the periphery of the inner sheet 100 and the outer sheet 300 is stitched, ultrasonically fused or heated. It is made by bonding by fusion.

In addition, the functional sanitary napkin of the present invention may further comprise an auxiliary adsorption member 400 for further use in the case of a large amount of secretion, such as menstrual blood, depending on the woman as shown in FIG.

Similarly to the adsorption member 200, the auxiliary adsorption member 400 may be made of cotton fibers, wool fibers such as wool, goat wool, or the like in the form of cotton, or a polymer absorbent such as sodium polyacrylate. Like the adsorption member 200, the outer shell may be made of a nonwoven fabric or the like.
