Let's do it.
- the component separator 100 is basically configured as described above. Hereinafter, a process of separating the body fluid using the component separator 100 will be described.
- the component separator 100 should be in a state where the plunger 132 is in close contact with one end side. At this time, it is possible to connect the syringe and the component separator 100 by using the connector 170 shown in FIG. In particular, it is more preferable that the component separator 100 is provided with a lower stopper 142 because the air remaining in the component separator 100 can be discharged slowly, thereby allowing the charging of quiet blood. Do.

- a screen not shown
- Meshes are placed inside the cell strainer, and each mesh should have an eye size of 100 micrometers or less. The reason for using a mesh of 100 micrometers or less is that when injected into the human body, it passes through the smallest capillaries.
- a general syringe may be used as the component collector 200, and a container 202 having a space therein, a moving member 204 moving inside the container 202, and an integral part of the moving member 204 may be used. It may include a push rod 206 to be connected, and a connector 208 formed at one end of the container 202 and connected to the connector 170.

- the plunger 132 may be approached while engaging with the unit 122.
- the former method can shorten the working time more. In the latter method, the components inside the main body 110 can be discharged silently without mixing with each other.
- the PRP After the PRP is moved to the component collector, and connected to one end of the connector with a screen (cell strainer), the other end of the connector by connecting a new component collector, filtering the PRP mesh (mesh) or cell straining).
- the reason for filtering the mesh is to filter out foreign substances during the injection of the human body and to prevent the formation of blood clots due to cell masses. Therefore, it is possible to isolate the desired blood component.
- the pressing projection 162 Hides into the push tube 150.
- the holding portion 167 of the pressing screw portion 158 as shown in Figure 4, the neck portion 136 of the plunger 132 to hold the pressing member 148 and the plunger 132. Allow them to move in one piece.
- the plunger 132 can be retracted.
- the inhaled fat is decanted or centrifuged to remove the water and obtain pure fat.
- the collagenase solution mixed with saline and collagenase is mixed with pure fat, decanted or centrifuged again, and the target solution containing the stem cells collected at the lower side is charged into the component separator 100. .
- the component separator 100 is inserted into a centrifuge (not shown) to separate the target solution into layers.
- 12 shows that the target solution is divided into layers, and the stem cell solution 4 collected in the concave groove 140 is divided into the supernatant solution 5 disposed above the stem cell solution 4.
- the liquid located on the upper side in the same manner as the blood component separation method is discharged.

- the handle 164 to facilitate the retraction of the plunger 132, the pressing protrusion 162 to hide inside the push tube 150.
- the component separator 100 into which the washing solution is charged is put back into the centrifuge and the layers are separated.
- the stem cell solution obtained in the collection unit is moved to a new component collector 200.
- the connector 210 equipped with the screen 216 may be used.
- the stem cell fluid is transferred to the component collector and then connected to one end of the connector with a screen (cell strainer), and a new component collector is connected to the other end of the connector to connect the stem cell fluid to the screen 216.
- Stem cell fluid extraction can be completed by filtering (meshing or cell straining) of the mesh.
- the reason for filtering the mesh is that even with collagenase enzymes, some extracellular matrix may be present without complete dissolution, resulting in vascular obstruction or entanglement of cells with each other during human injection. It is to prevent clot formation due to lumps. In this case, if a connector having two inlets exists at the top, the mesh can be filtered and the nutrient solution or drugs can be easily added to the stem cell solution.
- the screen may have different sizes of meshes (ie, the number of eyes per unit area of the screen may be set differently).
- a drug such as a nutrient solution and the like are used.
- Stem cell solution can be charged into the component collector 200 at the same time, it is possible to perform a quick separation more convenient.
- the bone marrow is first extracted using a special bone marrow extraction needle from a site such as an iliac bone, and then extracted using the aforementioned blood separation method and adipose derived stem cell separation method. have.
- FIG. 17 is a cross-sectional view of the bone marrow extract charged into the component separator 100, the upper stopper 180 and the lower stopper 142 are assembled, and the bone marrow extract is separated by a centrifuge. From the lower side, blood cells 6, bone marrow stem cell fluid 8, and plasma 7 are arranged in this order.
