Description
ADHESIVE SHEET FOR PROMOTING CIRCULATION OF BLOOD USING
PYROLIGNEOUS LIQUID AND METHOD FOR MANUFACTURING THE SAME
Technical Field
The present invention relates to an adhesive sheet for promoting circulation of blood using pyroligneous liquid and a method for manufacturing the same. More particularly, the present invention relates to an adhesive sheet having a ceramic treated surface to which pyroligneous liquid is sealed up, the pyroligneous liquid having gone through a series of processes, starting with three-staged refining and processing, a mixing process with effective components, a ripening process, a drying process, and a mixing process again with the effective component at a predetermined ratio.
Background Art
Pyroligneous liquid is an acidic liquid with a pH 3, which is produced when a wood is thermally decomposed. Technically, pyroligneous liquid is obtained by liquefying fumes collected from a carbonization process of wood. For that reason, pyroligneous liquid enriched with effective components available in the wood, and has drawn a lot of attention from diverse industrial fields.
Especially, pyroligneous liquid has been in favor of medical fields as a curing supplement. However, one should be very careful to use the pyroligneous liquid with other medicines because it contains plenty of harmful substances, e.g. tar, methanol, or cresol. Hence, before applying the pyroligneous liquid to a human body, every harmful or poisonous substance should be completely removed from it through a high
degree of refining process.
To many, the pyroligneous liquid is known very effective to swiftly remove subcutaneous harmful substances once it is applied to the skin, and further to promote metabolism, thereby recovering a cutaneous lesion early. To be able to apply the pyroligneous liquid to a lesion of an epidermis by using an adhesive sheet, however, one should congeal the pyroligneous liquid to a certain degree. For instance, Japanese Patent Publication No. 1999-377391 discloses a technique for making pyroligneous liquid to fine power by mixing the pyroligneous liquid with crystalline cellulose, starch, and PCS, and drying the mixture at 50°C. Another Japanese Patent Application No. 99-207184 and Japanese Utility Model & Device Application No. 99-5455 introduced an adhesive sheet for promoting circulation of blood, wherein a mixture of dry pyroligneous liquid with starch with spray-adsorbent effective components is applied to the sheet. However, the above technologies proved inappropriate for completely removing plenty of harmful substances contained in raw pyroligneous liquid, and the effective components' activation and their hypodermic absorption were still remained questionable because a simple mixing process on the effective components could not guarantee such effects.
Disclosure of Invention
It is, therefore, an object of the present invention to provide an adhesive sheet for promoting circulation of blood using pyroligneous liquid and a method for manufacturing the same. To achieve the above object, there is provided a method for manufacturing an
adhesive sheet with one side being subject to a ceramic treatment for an application of a mixture of pyroligneous liquid free of harmful substances with other effective components, namely elvan, Agaricus pieade, and dry centipede, for promoting circulation of blood and hypodermic absorption, the mixture having gone through a ripening process followed by a drying process using a fluidized-bed dryer in order to maximize an activation of the effective components and uniformly mix a very small amount of effective components. After all, the ceramic coating treated surface of the adhesive sheet, to which the pyroligneous liquid with much stronger effect of the circulation of blood is applied, is attached to the skin.
Best Mode for Carrying Out the Invention
A preferred embodiment of the present invention will now be described. To begin with, provided here is a method for manufacturing an adhesive sheet using pyroligneous liquid, which includes: a first step for collecting fume produced by carbonation (or burning) of material wood, naturally cooling the fume to obtain pyroligneous liquid therefrom, and leaving the pyroligneous liquid in a vessel for a predetermined period of time until the liquid is separated to three layers; a second step for extracting the middle layer out of the three-layer pyroligneous liquid, and repeating a distillation process on the middle layer until the middle layer is sufficiently purified; a third step for mixing the purified pyroligneous liquid with an activated carbon for stirring, and removing any harmful substances through an adsorption process; a fourth step for heating the purified pyroligneous liquid by the activated
carbon at a low temperature for removing harmful substances out of the pyroligneous liquid through a fractional distillation method, and again heating the pyroligneous liquid at a high temperature for removing still remaining harmful substances through the fractional distillation method; a fifth step for mixing the pyroligneous liquid free of harmful substances with okapi, kalopanacis cortex, centipede powder, and plant powder, stirring the mixture at a low speed, and ripening for 5 to 10 days; a sixth step for adding starch and crystalline cellulose to the ripened pyroligneous liquid, and drying at a predetermined temperature for producing pyroligneous powder; a seventh step for performing a spray drying or vacuum-freeze process on the pyroligneous powder; an eighth step for mixing 20-60% of the pyroligneous power with 40-80% of a mixture liquid containing starch, elvan powder, and plant powder, stirring the mixture, and conducting a fluidized-bed drying process on the mixture at a low temperature; and a ninth step for sealing the final pyroligneous mixture prepared hitherto inside a SMMS adhesive sheet, in which one side of the sheet goes through a ceramic surface treatment to be in contact with the skin and the other side is foiled. As for a fractional distiller at the first step, the ratio of width to length of the distiller ranges from 1 :3 to 1 :8. If the ratio is below 1 :3, it becomes very difficult to obtain the pyroligneous liquid since the middle layer's contact area is relatively large compared to the total volume of the pyroligneous liquid. On the other hand, if the ratio is above 1 :8, the distiller is too large to use although it might be able to separate the liquid much better. Preferably, the separation or distillation lasts for 2 - 6 months.
If the separation is done within two months, one cannot obtain more purified pyroligneous liquid. Meanwhile, if the separation period does not need to further than 6 months because there would be nothing more to be separated. Particularly, the activated carbon adsorption process employed in the third step is for removing harmful substances with a high boiling point, such as, benzopyrene, phenol, and cresol. Preferably used activated carbon is 0.5cm to 2.0cm in diameter, and the volume of the activated carbon to be used is 20-30% of the total volume of the pyroligneous liquid. If the activated carbon is shorter than 0.5cm, the adsoφtion ability is not very good, and if the activated carbon is longer than 2.0cm, it is easily broken during the stirring step, producing activated carbon suspended matters. In addition, if the total volume of the activated carbon is below 20% of the total volume including the pyroligneous liquid, the adsoφtion capacity becomes very low. On the other hand, if the volume of the activated carbon exceeds 30% of the total volume, the adsoφtion capacity becomes so excessive that some effective components could be adsorbed as well. A desirable stirring frequency is 20-60 times per minute because when it is less than 20, the adsoφtion efficiency becomes poor, and above 60, the activated carbon might be broken.
At the fourth step, the pyroligneous is first refined at a low temperature of 60 - 70°C, and then refined at a high temperature of 100 - 110°C. The low temperatured refining process is for getting rid of harmful substances with a low boiling point, e.g. methanol (b.p.: 64.1°C) and the high temperatured refining process is for removing harmful substances with a boiling point around 100°C which is the boiling point of water. Particularly, 100°C is chosen to protect a main component of the pyroligneous liquid, that is, acetic acid whose boiling point is 117.8°C.
At the sixth step, the composition ratio of the mixture (starch: crystalline cellulose) is 10-20%: 20-30% for 60-70 wt.% of the pyroligneous liquid. The mixture is then dried based on a hot wind drying method in which 40-50°C of dry air current passes the mixture from both directions.
At the fifth step, the plant powder is composed of aloe essence, chito- oligosaccharide, Poria cocos, agaricus pieade, sea tangle powder, and green tea powder. To be more specific, 10-25 wt.% of the pyroligneous liquid, 70-85.5 wt.% of starch, 0.5- 1 wt.% of okapi, 0.5-1 wt.% of kalopanacis cortex, 0.5-1 wt.% of centipede powder, 0.5-1 wt.% of aloe essence, 0.5-1 wt.% of chito-oligosaccharide, 0.5-1 wt.% of Poria cocos, 0.5-1 wt.% of agaricus pieade, 0.5-1 wt.% of sea tangle powder, and 0.5-1 wt.% of green tea powder. An appropriate rotational speed of a stirrer ranges 30 to 80 times per minute, and the stirring and ripening processes continue until the final viscosity of the mixture reaches 0.2 - 0.3 Pa • s. At the seventh step for drying, the ripened viscous pyroligneous mixture is sprayed through a nozzle, and becomes particulate at a size of smaller than 0.5mm. After that, the particulates go through a rotating-drying process in a revolving wind. Further, the dry mixture is subject to a freeze dry process at a temperature between - 20°C and -40°C under a reduced pressure at about 0.02-0.14 psi in order to sublime moisture therein.
At the eighth step for drying, added to the pyroligneous mixture are starch, elvan powder, and plant powder. This mixture is particularly placed in a vessel whose bottom portion is a perforated plate. A hot wind flows into the perforated plate to cause a vehement fluidization movement inside, thereby drying the mixture. The dry mixture is then released through a fan and its particle size becomes uniform. The plant
powder includes aloe essence, chito-oligosaccharide, Poria cocos, agaricus pieade, sea tangle powder, propolis red ginseng, and green tea powder. As for the elvan powder, an elvan is pulverized to a size of 60-300 mesh. If the elvan particulate is smaller than 60 mesh, it is so minute that it can pass through a hole (or aperture) of the adhesive sheet surface member, while if the elvan particulate is larger than 300 mesh, it is so big that it can cause a patent who applied the adhesive sheet to his skin to feel uncomfortable. Preferably, the mixture includes 15-25 wt.% of pyroligneous liquid, 60-76 wt.% of starch, 6-7 wt.% of elvan powder, 0.5-1.0 wt.% of aloe essence, 0.5-1.0 wt.% of chito-oligosaccharide, 0.5-1.0 wt.% of Poria cocos, 0.5-1.0 wt.% of agaricus pieade, 0.5-1.0 wt.% of sea tangle powder, and 0.5-1.0 wt.% of green tea powder.
At the ninth step, a SMMS type nonwoven fabric is usually used for the adhesive sheet. More specifically, the nonwoven fabric is a quadruple layer consisting of a spunbond, a meltblown, a meltblown, and a spunbond. In this manner, the pyroligneous liquid particulate is not easily oozed out. Also, one side of the adhesive sheet to be in contact with the skin is sprayed with a liquid adhesive, namely pine resin, a pulverized ceramic substance at a size of 150-300 mesh, and the pyroligneous mixture solution. The other side of the adhesive sheet is (aluminum) foiled, whereby effective components in the pyroligneous liquid mixture can be completely protected from the outside.
Embodiment 1. Refining Pyroligneous Liquid
An oak tree was carbonated in a furnace at 1300°C, and a collecting pipe that is installed above the furnace collected fumes produced from the carbonation. Later, the collected fumes were put in a separate tank and a cooling pipe installed inside the tank continuously liquefies the fumes. Thusly obtained pyroligneous liquid was sealed in a
glass bottle with 20cm in diameter and 130cm in height and left out for three months. In due time, the middle layer was separately collected, and after two months, it was again put in the same sized glass bottle used before to distill the middle layer. Particularly, the tank for collecting the pyroligneous liquid is made of resin to prohibit the tank from being eroded by the acidic pyroligneous liquid (ph « 3).
20kg of the distilled layer of the pyroligneous liquid was placed in a stirrer, and 25 vol.% of an activated carbon with 1cm in diameter was added thereto. The mixture was then stirred at a speed of 40 times per minute. Once the pyroligneous liquid was refined, it passed through a nonwoven fabric to get rid of the activated carbon.
The pyroligneous liquid, having been refined through an adsoφtion of the activated carbon, was heated at 60°C for 30 minutes to removing harmful substances with a low boiling point. The pyroligneous was heated one more time at 100°C for 15 minutes for removing harmful substances with an intermediate boiling point.
Embodiment 2. Producing Pyroligneous Liquid Powder 20kg of the refined pyroligneous liquid obtained from Embodiment 1 was mixed with 3kg of starch and 7kg of crystalline cellulose. To stir the mixture, a hot wind with a temperature of 45°C passed through the mixture from both directions. 20kg of the resulting pyroligneous liquid was again mixed with 8kg of starch,
80g of okapi, 70g of kalopanacis cortex, 80g of centipede powder, and 80g of green tea powder, and stirred in a stirrer at a speed of 60 times per minute, and then ripened for 7 days. The ripening temperature was maintained at 30°C.
Later, 20kg of the ripened pyroligneous mixture was put in a cooling tank at 35 degrees below zero and freeze dried under a reduced pressure. 20kg of thusly
processed pyroligneous liquid was injected to a fluidized dryer and a hot wind at 40°C was blown therein. Added to the dry pyroligneous liquid was 50g of propolis 50g, 80g of red ginseng, and 80g of chito-oligosaccharide, while coating and drying the pyroligneous liquid. Further, 1kg of the dry fluidized bed powder and 1kg of the freeze-dry powder were mixture together.
Finally, 2kg of the dry pyroligneous liquid power was mixed with other effective components, that is, 7.2kg of starch, 600g of elvan powder at 200mesh, 40g of aloe essence, 80g of chito-oligosaccharide, 85g of Poria cocos, 95g of agaricus pieade, 90g of sea tangle powder, and 1 OOg of green tea powder, to produce a final product.
Embodiment 3. Manufacturing an Adhesive Sheet
Using a spunbond and a meltblown with 5cm in width and 10cm in height, respectively, a quadruple layered nonwoven fabric, composed of a spunbond, a meltblown, a meltblown, and a spunbond, was prepared. With two pieces of the fabric, a mixture of pine resin and ceramics at 250mesh was sprayed to one side of one fabric. This side becomes an inner side. On the other hand, an adhesive was applied to the other three outer sides of the two fabrics, and these two nonwoven fabrics were adhered together. After that, 3.5g of the mixture produced from Embodiment 2 was put inside, and the other side was adhered thereto for sealing the mixture inside the adhesive sheet, and the outer surface of the adhesive sheet was foiled.
While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
