FIG. 21 is an enlarged photograph of the 75 times magnification of the vicinity of the third cutting portion of the herringbone thunderstorm according to one embodiment of the present invention finally completed through the aging process.

As shown in FIGS. 1 and 2, the material of the fastball according to an embodiment of the present invention uses a fastball which can be easily found around the human body and is easily cultivated.

Scientific name of the foxtail is Setaria viridis (L.) P.Beauv. there is. viridis. The biological classification is as follows: flowering plants> monocotyledonous plants> liana> paddy fields, and the characteristic classification is annual plants.

Origin is native to Korea and can be found in tropical and temperate regions. Wild flowers are native to fields, roads and vacations, and are easy to cultivate. When cultivated around June to July in the lunar calendar, And is a plant capable of mass production through the harvesting of mature lepidoptera, whose leaves are turned from blue to golden. Flower color is light green or purple, and flowering time is from July to August.

The rootstock has a length of about 40 to 70 cm, feathers of 10 to 20 cm on the upper edge of the stem, and microscopic protrusions are formed on the surface of the stem at the connection between the stem and the feathers. The lobe plays a role of scraping off the eosinophil through the friction during the operation of the upper eyelid and lower eyelid.

In the case of the teratoma, the teratophyllite according to one embodiment of the present invention is obtained by cutting the first cut part 1 shown in FIG. 6 after collecting the larvae matured through the wild state or cultivation and then collecting the lower part of the upper part 'a' The portion of the stem ('b') having a length of 10 to 20 cm remaining after cutting the second cutting portion 2 is made through disinfection and cutting of the third cutting portion 3 after drying processing. As shown in FIGS. 18 and 20, since the foreign matter is removed through the disinfection treatment with a predetermined strength through reduction of moisture through the drying treatment, foreign matter is removed from the surface of the trunk end, which is 0.3 to 2 cm long, It is possible to obtain a hot-frosted throat according to an embodiment of the present invention in which fine protrusions are uniformly formed.

Therefore, when using the fat-filled throat according to one embodiment of the present invention, it is easy for the oriental doctor to grasp the thigh-like throat during the operation of the upper eyelid and lower eyelid, and since the intestine has a predetermined strength, It is possible to prevent the skin from being broken or detached, to give an impact to the eyes or eyes of the patient, or to prevent inflammation.

Also, as shown in FIG. 19 and FIG. 21, the fat-like throat needle according to an embodiment of the present invention can further improve the strength characteristics by further removing moisture from the entire thigh-like throat, especially the fine protrusions through an aging process.

The method for manufacturing a fattening throat needle according to an embodiment of the present invention starts with the maturing step (S10).

As shown in Fig. 1, the stamens and leaves of the pre-August lunar August are in an immature state with a blue color. However, after August August, stem and leaf become golden and become mature as shown in Fig. It is a very useful plant that can be mass-produced in a large number of giant herbaceous throat because there is no problem in obtaining the material because it is a plant which can be commonly found in the wild as well as an artificial dragon plant.

As shown in FIG. 6, from the middle of August to the beginning of September of the lunar approximate lunar calendar, the mature terracotta fur is divided into a feather ('a') formed on the upper edge and an upper stem ('b') part connected to the feather The first cut portion 1 is cut so as to remain at about 25 to 30 cm.

FIG. 7 is a photograph of the grasshopper collected in the immature state and the grasshopper collected in the mature state in order to explain the difference of the microprojections in the vicinity of the tertiary cut part 3 of FIG. 6 to be described later according to the harvesting time.

Then, the cutting step (S20) is performed to cut the cut part (2) of the secondary 6, which is the lower end part of the plumage ('a') part of the obtained grass roll.

That is, the feathers ('a') are removed by cutting about 2 to 3 cm above the top of the tertiary cuts 3 in which the fine protrusions are formed, so that the secondary cuts 2 are cut, Lt; / RTI >

In the cutting process, the second cutting portion 2 is first cut without cutting the third cutting portion 3 immediately. The reason for this is that when the extracted cuttlefish is not yet subjected to the drying process, the strength of the microprojections formed on the surface of the stem near the tertiary cutter 3 is weak, To prevent problems such as side effects that may occur during the procedure of the alveolar surgery due to the shape change or breakage.

As shown in the enlarged photograph of the 75th electron microscope near the tertiary cut part 3 of the immature flatborn cut in the secondary cut part 2 shown in FIG. 9, in the case of immature flatborn, the stem is not straightened and the micro- It is not appropriate to use it as a product. On the other hand, as shown in Figs. 10 and 11, when the matured females were cut at the 70th and 75th times of the electron microscope in the vicinity of the third cutting portion 3 of the mature females cut from the second cut portion 2, The stem was straight and the growth of the fine protrusions was completed and it was confirmed that it was suitable for use as a thorn. For this reason, it is necessary to collect the mollusc at the mature condition for use as a thirsty frost, so that the above-mentioned restriction condition occurs at the sampling time.

However, as shown in the enlarged photograph of 500 times magnification in FIG. 12, in the case of the mature females cut off from the secondary cut part 2, since a large amount of foreign substances such as dust and bacteria are adhered to the fine protrusions, And if a direct infusion treatment is performed on the upper and lower eyelids without performing a sterilization operation, serious side effects may be caused by inducing infection or the like in the surrounding tissues around the eyes and eyes.

In order to solve such a problem, an immersion step (S30) in which the secondary cut part (2) is immersed in ethanol for disinfection is performed.

That is, as shown in FIG. 13, immersion in ethanol for disinfection is carried out in a container containing ethanol for about 12 to 48 hours so as to completely submerge the herringbone. In this embodiment, the immersion is carried out for 24 hours. Through the process of immersion in ethanol for disinfection, the dust adhering to the fine protrusions naturally floats on ethanol and is separated, and bacteria and the like are sterilized.

Meanwhile, it is possible to remove some foreign substances and bacteria by an artificially whitening process of the foxtail cut off the second cutting portion (2) before the immersion step. In order to remove some water on the surface, An additional drying process may be performed at room temperature.

After the immersion step S30 is completed, the first drying step S40 is performed.

That is, the ethanol for disinfection near the third cutting portion (3) of the duckling which has been immersed is removed by drying.

It is preferable that the primary drying step is naturally dried for 12 hours to 72 hours at room temperature under a well-ventilated shade condition to remove ethanol for disinfection in the vicinity of the third cutting section. In this embodiment, the drying process was performed for 24 hours.

In the first drying process, it is preferable that drying is performed in a state where the tertiary cut portion is arranged so as to face upward as shown in FIG. 14 so that the ethanol for disinfection which is located near the third cut portion flows downward and is easily removed.

It is preferred that the above-mentioned normal temperature is maintained at a constant temperature of 5 to 40 ° C. In order to prevent the shape deformation due to abrupt drying and to shorten the drying time, It is more preferable to maintain the temperature, and in this embodiment, the drying process is performed while maintaining the temperature constant at 20 ° C.

As can be seen from FIGS. 15 to 16, which are photographs of the microprojections near the third cutting portion of the larvae after the primary drying, it can be seen that the foreign matter remaining in the vicinity of the microprojections is remarkably reduced after the immersion step and the drying step.

After the primary drying step (S40), the secondary drying step (S50) may be further performed if necessary.

Since the disinfecting ethanol in the vicinity of the tertiary cutting part is dried down in the primary drying step (S40), the sterilization ethanol flows downward and is set up so as to be easily removed. In some cases, There is a possibility that the ethanol is not removed but remains. Therefore, if necessary, ethanol for disinfection which remains in the entire petioles after the primary drying of the ethanol for disinfection in the vicinity of the third cutting portion can be completely removed by further drying.

In the second drying step, as shown in FIG. 17, the remaining hot springs remain in the whole hot springs which are naturally dried for 5 to 20 days in a sideways state as shown in FIG. 17 so that the disinfecting ethanol remaining at room temperature in a well-ventilated shade condition can be easily evaporated It is preferable to remove the ethanol for disinfection as much as possible. In this example, natural drying was performed for 7 days.

It is preferable that the above-mentioned normal temperature is maintained at a constant temperature (more preferably 15 to 23 ° C) in the range of 5 to 40 ° C as in the primary drying step.

When the secondary drying step (S50) is completed, the strength of the petioles, particularly the microprojections of the tertiary cutting portion (3) is increased. Even if the vicinity of the tertiary cutting portion (3) is cut, the shape change or breakage of the microprojection can be minimized Therefore, after the third cutting step (S60) is performed.

That is, the vicinity of the tertiary cut part 3 shown in FIG. 6 is cut so that fine protrusions can be formed in a length of 0.3 to 2 cm at the end of the stem ('b') of the dried plant.

When the cutting is completed, the shape of the teratoma can be completed as shown in FIG. 18, and the procedure can be performed.

However, it is more preferable to perform the aging step (S70) after the cutting operation in order to exhibit sufficient strength and increase the fixation force of the fine protrusions for the smooth operation of the fat-filled throat.

In other words, the stems of the third truncated leopard skin are aged for additional moisture removal to increase the strength. In the ripening process, it is preferable that the stem of the third cut slug is naturally matured for 1 to 5 years at room temperature in a well-ventilated shade condition to further remove moisture to increase the strength. In this example, natural aging was performed for 3 years.

Preferably, the normal temperature is maintained at a constant temperature (more preferably 15 to 23 ° C) in the range of 5 to 40 ° C.

Figs. 20 and 21 show that the microprojections are more firmly sharpened by removing water after aging as a photograph of the boll microflora before and after aging, and the strength is further increased.

When the fermentation is completed, the fermentation needle having the predetermined strength necessary for the treatment of the venipuncture and having the microprojections with the foreign substance removed and sterilized is completed (S80) as shown in Fig. 19

As described above, according to the manufacturing method of the fat-like superabsorbent needle according to the embodiment of the present invention, it is possible to produce fine needle-like thorns on the surface of the tip of the stem so as to be able to perform treatment according to the upper eyelid and lower eyelid therapy using a stable, It is possible to easily process the bolls having the protrusions, that is, the fine bolls. Thus, there is an advantageous effect that it is possible to easily mass-produce and supply a safe fat-fed throat, which is easy to perform the procedure of blood transfusion therapy and is free from the side effects due to infection or the like.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, And falls within the scope of the invention.
