Description

  The present invention relates generally to a wet towel supply device for disinfection and sterilization, and more specifically, a warm wet towel supply for disinfection and sterilization capable of supplying a warm wet towel for disinfection and sterilization. Relates to the device.

  The number of care service subjects wearing diapers has increased, and the frequency of use of towels (including non-woven fabrics) to clean the crotch soiled with manure during diaper replacement has increased. Among them, many wet towels containing alcohol are available for ease of use and prevention of infection. Alcohol solution has a disinfecting and disinfecting power and is very convenient for maintaining cleanliness. However, due to the strong degreasing power of alcohol, the skin of the crotch is inflamed, causing pain to the user, but the user is now patient and enduring this pain. In addition, since alcohol is a volatile solvent, it is kept as low as possible during storage to prevent evaporation, so a cold towel comes in direct contact with the user's crotch, I am changing diapers because my mind and heart are shrinking. Moreover, it must accept the unusual coldness that is cooled by the heat of vaporization due to the rapid evaporation of alcohol. Caregivers wear rubber gloves to prevent rough hands and infections, so they are immune from irritation and coldness.

  In connection with this idea, the inventors found that a drug containing an organic acid zinc at a concentration of 5,000 ppm to 10,000 ppm has the ability to inactivate avian Haemophilus influenzae. It proposed using as a chemical | medical agent (patent document 1).

Japanese Patent Application No. 2008-324201

  The inventors have conducted further intensive research on a drug containing the above organic acid zinc at a concentration of 5,000 ppm to 10,000 ppm, and found that this drug functions as disinfectant sterilization and deodorization instead of alcohol. The present invention has been completed.

  An object of the present invention is to provide a warming towel supply device for disinfection and sterilization that can supply a warm wet towel for disinfection and sterilization that does not feel cold.

  Another object of the present invention is to provide a warming towel supply device for disinfecting and sterilization that can supply a wet towel for disinfecting and sterilizing that does not cause inflammation on the skin.

  Another object of the present invention is to provide a warming towel supplying apparatus for disinfecting and sterilizing that can supply a wet towel for disinfecting and disinfecting without using a volatile solvent.

  Another object of the present invention is to provide a warming towel supply apparatus for disinfecting and sterilization improved so that a portion contaminated with excreta can be deodorized and diapers can be changed smoothly.

  A warming towel supply device for disinfection and sterilization according to the present invention is a device for supplying a wet towel for disinfection and sterilization that is warm to the skin, and a container and an organic acid metal placed in the container. A wet towel impregnated with a drug containing 5,000 ppm to 10,000 ppm, and a heating means for heating the wet towel provided in the container. The material of the wet towel is a hygroscopic towel made of cloth or pulp rayon paper, and includes a nonwoven fabric.

  The drug is obtained by dispersing metal oxide nanoparticles having a diameter of 50 nm to 70 nm in an organic acid aqueous solution. As the metal particles, zinc nanoparticles or platinum nanoparticles are preferable.

  The organic acid is gluconic acid, acetic acid, citric acid, tartaric acid, malic acid, lactic acid or the like. Among them, gluconic acid that is partially lactated when dissolved in water is preferable.

  By adding 1,3 dimethyl-2-imidazolidine, the solubility of organic acid zinc in water can be increased. 1,3 dimethyl-2-imidazolidine is not toxic.

The zinc oxide nanoparticles preferably include zinc oxide nanoparticles having a diameter of 50 nm to 70 nm (one nano is one billionth). A platinum nanocolloid solution may be used. It is also advantageous that ultrafine zinc oxide is well dispersed in organic acids. Metal ions are said to have sterilizing power in the order of Hg>Ag>Cu>Zn>Fe> TiO ₂ , and silver antibacterial agents are generally used. However, by making zinc oxide into ultrafine particles, It has come to show disinfection and bactericidal properties not inferior to. The mechanism of sterilization of ultrafine zinc oxide is considered to be the same as that of silver ions, and is not due to the toxicity and bactericidal properties of metals. It is thought that some oxygen in the air or water is activated to destroy the cell membrane of the fungus. . By using nanoparticles, the specific surface area is increased, the contact on the surface of the fungus is expanded, and the growth of the fungus is suppressed. Metal ion powder has little elution, high inhibitory effect maintenance and safety, and exhibits antibacterial properties equivalent to silver against bacteria that come into direct contact. In addition, the diameter of bacteria is 75 nm. It has been found that by selecting ultrafine zinc oxide having a diameter close to that of the fungus and dispersing it in an organic acid aqueous solution, the fungus can be inactivated.

When impregnating the drug into a wet towel (including non-woven), in terms of solid coating weight of the zinc oxide nanoparticles are preferably ^{5g / m 2 ~15g / m 2} .

  As the organic acid, an organic acid that is partially lactated when dissolved in water is preferable. In particular, gluconic acid is preferably used. In this case, more preferably, the concentration is adjusted to include about 7500 ppm of zinc gluconate.

When gluconic acid is dissolved in water, as shown in the following [Chemical Formula 1], a part becomes gluconolactone. This is called equilibrium. The ratio of gluconolactone and gluconic acid varies with temperature, concentration, pH, and the like. When acidified, the amount of acid in water increases, so the proportion of gluconolactone increases. When alkaline, gluconic acid becomes a salt and stabilizes, so the proportion of gluconolactone decreases. Equilibration is like connecting two water tanks with a tube. When water is poured into the left water tank, the water flows to the right through the tube to maintain balance.

Regarding the explanation of the synergistic effect caused by the combined use of zinc oxide nanoparticles and gluconic acid, let us consider the case where gluconic acid touches a protein, avian influenza. As shown in [Chemical Formula 2], the protein contains an acidic amino acid and a basic amino acid. Amino acid of the acidic, has a such as -COOH, the negative ion ^- become (COO). Basic amino acids have -NH2 and become positive ions (-NH3 ⁺ ). If there are a lot of positive ions in the protein or a lot of negative ions, the protein will dissolve in water, but if the negative and positive ions are the same (referred to as the isoelectric point), they will be neutral and have no charge. It will not dissolve in. If the fungus is made to have an isoelectric point, the fungus will not dissolve, and it will clump and die.

  According to the present invention, the zinc oxide nanoparticles react with gluconic acid to become zinc gluconate, which successfully adjusts the isoelectric point to destroy the fungal cells and inactivate them. It is done.

  It is preferable to further provide a heat storage material for storing heat in the container.

The above non-woven ^{fabric, 30g / m 2 ~50g / m} 2 of PET (polyethylene terephthalate) preferably comprises a spunbonded fabric.

Further, the nonwoven fabric of ^{30g / m 2 ~50g / m 2} , may be 70% and PET30% of混抄nonwoven rayon.

  The organic acid metal may be platinum citrate.

  The inside of the container is preferably kept at around 40 degrees Celsius (37 ° C. to 43 ° C.).

  It is preferable to further provide a spray bottle filled with a medicine containing organic acid zinc at a concentration of 5,000 ppm to 10,000 ppm together with the wet towel in the container.

  According to the warming towel supply apparatus for disinfection and sterilization according to the present invention, a warm, skin-friendly wet towel that can be disinfected and sterilized can be supplied to users.

It is a conceptual diagram of the warming towel supply apparatus for disinfection sterilization concerning this invention. It is the figure which plotted the relationship between the density | concentration of zinc gluconate in a chemical | medical agent impregnated in the wet towel used for this invention, and a fungal infectivity.

  Hereinafter, embodiments of the present invention will be described.

  FIG. 1 is a conceptual diagram of a warming towel supply apparatus for disinfection and sterilization according to an embodiment of the present invention. The warming towel supply apparatus 1 for disinfection and sterilization includes a container 2. As the container 2, for example, a poly bucket or the like can be used. A gel-like heat storage material 11 is provided in the container 2, and an organic acid zinc is concentrated on the heat storage material 11 at a concentration of 5,000 ppm to 10,000 ppm. A plurality of wet towels 3 impregnated with a drug (aqueous solution) contained therein are placed in a laminate bag 10. In the container 1, a heating element 4, which is a heating means for heating the wet towel 3, is provided under the wet towel 3 and the heat storage material 11 via a partition plate 6. The heating element 4 is formed of a heater that is heated by AC (alternating current) or DC (direct current), or slaked lime or iron powder (corrosion heat generation). The temperature is adjusted by the heating element 4 to keep the inside of the container 2 at around 40 degrees Celsius.

  A spray bottle 5 filled with a chemical containing an organic acid zinc at a concentration of 5,000 ppm to 10,000 ppm together with the wet towel 3 is disposed on the partition plate 7. The spray bottle 5 together with the wet towel 3 is also kept warm at around 40 degrees Celsius. The spray bottle 5 is used as a deodorant when changing diapers. The container 2 is sealed with a lid 8. The wet towel 3 and the spray bottle 5 can be freely taken out by opening the lid 8. The medicine is sprayed from the spray bottle 5 to sterilize and deodorize the crotch soiled with manure when changing diapers. The warming towel supply device 1 for disinfection and sterilization has a hand-held portion 9 and is portable. The heat storage material 11 prevents the wet towel 3 from being cooled during carrying.

  A drug containing organic acid zinc at a concentration of 5,000 ppm to 10,000 ppm is the same material as cosmetics, and has the power to protect the skin rather than roughening the skin. This drug has a strong bactericidal power and long-lasting power, and the bactericidal power of alcohol does not reach this. Because it is an aqueous solution, it does not vaporize as hard as alcohol even if the temperature is raised.

  A drug containing organic acid zinc at a concentration of 5,000 ppm to 10,000 ppm used in the present invention can obtain zinc oxide nanoparticles having a diameter of 50 nm to 70 nm in a gluconic acid aqueous solution containing 40 to 50% by weight of gluconic acid. It was obtained by stirring and dispersing at room temperature so as not to raise the temperature so that the concentration of zinc gluconate was 5,000 ppm to 10,000 ppm. It was observed that when zinc oxide nanoparticles were dispersed in an aqueous gluconic acid solution, heat was generated, and gelation occurred when the temperature was too high. Moreover, when the density | concentration of the zinc gluconate exceeded 60,000 ppm, it was recognized that it gelatinizes purely. Therefore, it should be noted that the temperature during dispersion and the concentration of zinc gluconate are strictly adjusted.

  Here, the effect of this drug will be described in detail in the case where avian influenza is used as the bacterium.

図２は、試験品中の Gluconic Zn の濃度と菌感染価との関係をプロットしたものである。図２から明らかなように、グルコン酸濃度７，５０００ｐｐｍで、菌感染価２．２５と極小値を示した。このような極小値を示す理由は定かでない。 In a 50% aqueous solution of gluconic acid, zinc oxide nanoparticles having a diameter of 50 nm to 70 nm are stirred and dispersed at room temperature so as not to raise the temperature, and zinc gluconate (Gluconic Zn) is 30,000 ppm, 10,000 ppm, 7, Six types of drug test products containing 500 ppm, 5,000 ppm, 3,750 ppm, and 2,000 ppm were prepared. Add 0.5 ml of each sample (sterilized distilled water as a control) and 0.5 ml of avian influenza (A / whistling swan / Shimane / 499/83 (H5N3) 10 ^7.5 EID ₅₀ / 0.1 ml), mix by vortexing, The reaction was carried out at room temperature (20 ° C.) for 10 minutes. The test product and the bacterial mixture are serially diluted 10-fold with sterile PBS containing antibiotics, and 0.1 ml is inoculated into the chorioallantoic cavity of three 10-day-old chicken eggs. After the cultured chicken eggs were cultured at 37 ° C. for 2 days, the presence or absence of bacterial growth in the chorioallantoic cavity was confirmed by the hemagglutination test, and the bacterial infection titer was calculated by the method of Reed and Munch. The results are shown in Table 1.

FIG. 2 is a plot of the relationship between the concentration of Gluconic Zn in the test product and the bacterial infectivity. As is clear from FIG. 2, the microbial acid concentration was 7,5000 ppm, and the bacterial infection value was 2.25, which was a minimum value. The reason for showing such a minimum value is not clear.

  In the above embodiment, gluconic acid is exemplified as the organic acid. However, the invention is not limited to this, and any one that breaks down the protein film in synergy with zinc oxide can be used.

  Moreover, although the case where the organic acid zinc was used was illustrated in the said Example, organic acid platinum may be used. In this case, a platinum nanocolloid citric acid distilled aqueous solution is preferably used. A non-woven fabric is impregnated with a solution containing 0.0225 g of platinum per liter, and platinum nanoparticles having a particle size of 4 nanometers are uniformly dispersed to form a wet towel. The phosphoric acid bond of bacterial RNA (ribonucleic acid) is cleaved by platinum catalysis to inactivate the bacteria.

  It should be understood that the embodiments disclosed herein are illustrative and non-restrictive in every respect. The scope of the present invention is indicated not by the above description but by the scope of the utility model registration request, and is intended to include all modifications within the meaning and scope equivalent to the scope of the utility model registration request.

  The warming towel supply apparatus for disinfecting and sterilization according to the present invention supplies a warming towel for disinfecting and sterilization that is gentle on the skin with reduced degreasing power, and reduces pain when changing diapers.
