Description
TECHNICAL FIELD The present invention relates to a fat separation container, and more particularly, to a fat separation container capable of separating and purifying impurities other than fat from fat tissue obtained from a living body.
Generally, implantation of implants and autologous fat injection are used for enlargement such as breast enlargement, facial molding (nose, chin, ball, etc.).
Injection of implants is easy to control the size and can be done at once. However, because it is inserted into the body, it is not clinically safe, and the feeling and feeling are not good. On the other hand, autologous fat injection sucks the remaining fat Because it is re-infused with poor chest, heap, face, etc., removal of unnecessary part and enlargement of poor part are done, so body balance is made and self-fat is injected directly, so there is no resistance to foreign substances and texture There is an advantage of feeling good.
However, in the case of autologous fat injection, the fat survival rate is extremely low to 20 to 50%, which is not enough to obtain the desired size. In order to obtain the desired size, 2 to 3 procedures are required, There is a problem. Therefore, various attempts have been made to increase the fat survival rate. As a result of clinical trials, the survival rate was improved by injecting only pure fat.
When the fat is inhaled from the human body, impurities such as blood, body fluids, aging cells and the like are sucked together as well as fat, so that a centrifuge can be used as a method for removing impurities and separating pure fat.
Autologous fat injection using a centrifuge is largely made up of liposuction, centrifugation, and fat infusion. Liposuction is usually performed by aspirating the suction bottle into a vacuum to inhale the fat, and centrifugation to make pure fat Separate centrifuges are used. In order to inject the fat that has undergone the centrifugation process into the body implantation site, it is common to inject the fat directly by hand using a syringe.
However, the centrifugal separation method for separating and purifying fat has a problem that it is merely for the purpose of removing moisture, and it is impossible to select cells, and the fat cells are liable to be damaged by the pressure of the centrifugal separator.
In order to solve such a problem, Korean Patent Publication No. 2014-0060843 discloses a fat tissue concentration system.
The above-mentioned fat tissue concentration system uses a filtration type filter bag instead of a centrifugal separation method in order to separate and purify pure fat from a fat tissue (untreated fat tissue) extracted from a human body and containing various impurities. The filter bag has a structure in which two filters, that is, a
The filter bag is divided into two
The inside of the above-described conventional filter bag is simply shown in Fig. The conventional filter bag is divided into the first and
Further, the tissue filter provided inside the filter bag has a problem in that the surface area is relatively small because both surfaces are formed flat. In addition, since both sides of the internal complementary filter located between the PVC film and the tissue filter are flat and wide, both sides of the internal complementary filter easily stick to the PVC film and the tissue filter.
SUMMARY OF THE INVENTION The present invention has been made to overcome the above-mentioned problems, and it is an object of the present invention to provide a method of manufacturing a semiconductor device having a first space portion into which an untreated fat tissue containing impurities is introduced and a second space portion into which impurities separated from the untreated fat tissue are introduced, And it is an object of the present invention to provide a fat separation vessel which can improve the separation effect.
To achieve the above object, according to the present invention, there is provided a fat separation container comprising: a storage bag formed by joining edges of a front sheet and a rear sheet facing each other; A separation membrane installed between the front sheet and the back sheet to divide the inside of the storage bag into a first space part through which untreated fat tissue flows and a second space part through which impurities separated from the untreated fat tissue are introduced; And a plate-shaped spacing member provided in the second space to separate the separation membrane from the back sheet, wherein a lower end of the second space is formed at a lower position than a lower end of the first space.
A plurality of first projections are formed on one surface or both surfaces of the separation membrane.
The first protrusions are formed to protrude into an arcuate shape.
A plurality of second projections are formed on one surface or both surfaces of the spacer.
The second protrusion is formed so as to protrude convexly in an arcuate shape.
As described above, according to the present invention, the first space portion into which the untreated fat tissue containing impurities is introduced and the second space portion into which the impurities separated from the untreated fat tissue are introduced are formed differently to improve the separation effect of impurities .
Further, since the first protrusions are formed in the separation membrane, the surface area of the separation membrane can be widened, and the effect of separating the impurities can be enhanced. Further, the second protrusions may be formed on the surface of the spacing member to reduce sticking of the back sheet and the separating film to both sides of the spacing member.

In the present invention, 'adipose tissue' is a connective tissue composed of adipocytes and fibers. Adipose cells are usually spherical, 50 ~ 100um larger than normal cells, and each adipocyte is wrapped with fibers and capillaries are distributed at high density between cells. These adipose tissues are found in the subcutaneous, major retina, and mesentery, especially in the kidney, heart surface, joints, and iliac bone. They are used not only as a storage nutrient but also as an energy source and prevent heat loss. . In addition, it has the function of filling spaces between tissues and supporting structures such as blood vessels and nerves. The term " untreated adipose tissue " refers to an adipose tissue extracted from the inside of the human body and containing impurities such as blood, body fluids, aging cells and the like.
