Description

[0001] Blood seperating vial for extracting PRP [0002]

The present invention relates to a blood separation and extraction container capable of precise PRP extraction, and more particularly, to a blood separation and extraction container capable of extracting PRP, which is capable of easily extracting a specific component of blood, that is, It is about the container.

PRP (platelet-rich plasma, abbreviated as 'PRP' hereinafter) refers to the platelet-rich portion of plasma, which is not a special processing or producing material but a component that can be obtained in the blood of the patient. The PRP obtained through the centrifugal separator using blood from the patient's own blood contains platelets 3 to 8 times as large as the platelet counts contained in plasma in the normal blood.

Platelets function to release growth factors involved in the recovery of injured tissue. These growth factors promote the tissue's natural recovery potential. For example, the composition of the regeneration environment, the promotion of blood vessel formation, the involvement of skin tissue and cell growth, and the promotion of regeneration of connective tissue. Recently, it has been used for cosmetic surgery. It is known that PRP is commonly used for tissue transplantation such as fat or cartilage transplantation, thereby increasing the engraftment rate of tissue. It is also used as an agent for improving skin aging by injecting directly into the skin to cause fine wrinkles. Since these PRPs are autologous blood components, side effects such as infection or rejection during the injection process are rare and have been used through many experiments and validation procedures.

In such a situation, conventionally, when extracting plasma by centrifuging the blood, it is difficult to extract the plasma only at a certain distance from the portion of the plasma that forms the boundary with the red blood cells, and to discard the rest, and to extract the desired amount. Further, since it is difficult to fix the position of the injector to be extracted, it is difficult to accurately extract it, and other components are sometimes extracted together with plasma.

In addition, since PRP (concentrated platelets) in the blood is very small, the volume occupied by the blood separation and extraction vessel is small and the layer is thin. However, in the conventional blood separation and extraction vessel, the needle is inserted downward from the upper lid. In this type of blood separation extraction vessel, during the extraction of the PRP, the needle of the syringe moves away from the PRP layer, There is a high possibility of extracting the components. In addition to PRP, blood or plasma containing erythrocyte components can cause pain in human skin.

Therefore, in the process of extracting PRP from blood, it is necessary to precisely extract only PRP so that other components of blood are not included.

On the other hand, Korean Patent Laid-Open No. 10-2011-0009651, etc., discloses a prior art relating to a blood separation and extraction container.

Disclosure of the Invention The present invention has been conceived to solve the problems of the conventional art as described above, and it is an object of the present invention to provide a blood extracting unit at the center in the lateral direction of the blood separation / extraction container, to infiltrate the syringe into the blood separation / extraction container laterally, It is an object of the present invention to precisely and easily extract a specific component of blood from a blood separation and extraction container while visually confirming the PRP layer with the naked eye.

The needle of the injector is infiltrated from the side of the blood extracting unit to extract a specific component of blood And a blood separation and extraction container.

Further, the blood extracting unit has a height larger than a distance between the upper accommodating unit and the lower accommodating unit, and when the blood extracting unit is coupled between the upper accommodating unit and the lower accommodating unit, the blood extracting unit is compressed and deformed to be concaved A left supporting wall and a right supporting wall are formed on both sides of the lower receiving portion, a mounting groove for receiving a syringe is formed on the left supporting wall, a magnifying glass is formed on the right supporting wall, A circular receiving portion is formed at the upper end of each of the left support wall and the right support wall and a hook projection engaging portion and a guide groove are formed in the receiving and coupling portion, And the upper receiving portion is formed with an insertion portion to be inserted into the receiving and fastening portion, And the needle of the syringe is infiltrated into the center of the depression of the blood extracting part by passing the inlet of the syringe through the mounting groove when the needle of the syringe is infiltrated into the blood extracting part, And the blood extracting unit is formed of a single transparent silicon material and is located in a space between the upper accommodating unit and the lower accommodating unit, and a blood inlet and an air outlet are formed in the cap And the blood inlet and the air outlet are sealed or opened through the opening and closing lid.

Further, the left support wall of the blood separation / extraction container according to the present invention is further provided with a needle mounting groove.

The blood separation / extraction container according to the present invention has the following effects.

First, in the blood separation and extraction vessel of the present invention, it is not necessary to remove the needle by inserting the needle of the syringe once in the extraction process of the blood by mounting the syringe in the mounting groove formed in the support wall. Therefore, the possibility of contamination of the syringe is small, The operation is omitted and the blood extraction operation is simplified.

Secondly, since the blood separation and extraction container of the present invention has the magnifying glass formed on the supporting wall, the PRP layer located in the blood extracting unit is enlarged through the magnifying glass while extracting the PRP with the injector, It is easy to extract only the PRP.

Third, since the blood extraction part formed of a transparent material made of a single material is formed, the diffuse reflection and refraction of the light are remarkably reduced, and the boundary of the PRP can be grasped visually.

Fourth, since the supporting wall and the receiving portion coupling portion for coupling the upper receiving portion and the lower receiving portion are formed, it is possible to prevent the blood extracting portion from being damaged even if an external force is applied to the blood separation and extraction container.

Fifth, precise extraction of PRP is possible because the needle of the syringe penetrates into the blood extracting part in a precisely horizontal state by the mounting groove of the support wall.

Sixth, when the upper receiving portion and the lower receiving portion are separated from each other, the blood extracting portion is press-coupled between the two, thereby improving the airtightness of the blood extracting portion.

However, some configurations which are not related to the gist of the present invention may be omitted or compressed, but the configurations omitted are not necessarily required for the present invention, and they may be combined by a person having ordinary skill in the art to which the present invention belongs. .

FIG. 1 is a perspective view of a blood separation / extraction container according to a preferred embodiment of the present invention, FIG. 2 is an exploded perspective view of the blood separation / extraction container shown in FIG. 1, FIG. 4 is a front view showing a state in which a needle of a syringe is infiltrated into the center of a blood extracting unit in the blood separation and extraction container shown in FIG. 1, and FIG. 5 is a cross- FIG. 5 is a cross-sectional view showing the rise of PRP according to the operation of the height regulating portion in the illustrated blood separation extraction container.

1 to 5, a blood separation and extraction container 1 (hereinafter referred to as a "blood separation and extraction container") capable of accurately extracting PRP from a side according to the present invention comprises a cap 10, 20, a lower receiving portion 30, a blood extracting portion 50, and a height adjusting portion 60.

The cap 10 is connected to the upper receiving portion 20 at the uppermost position of the blood separation / extraction container 1 according to the present invention and the blood inlet 12 and the air outlet 13 formed in the cap 10 are opened / Is sealed or opened through the cover (11). The blood sampled by the syringe 70 is injected into the blood inlet 12. At this time, the air outlet 13 is a hole for discharging the air inside the blood separation / extraction container 1 to the outside so that blood can be smoothly injected into the lower accommodating portion 30 through the upper accommodating portion 20.

The upper receiving portion 20 is made of a transparent plastic material having a space for receiving blood and observing the inside thereof. The lower portion of the upper accommodating portion 20 has an insertion portion 21 whose outer diameter is smaller than that of the upper portion and an upper bottleneck portion 28 is formed at the lower end of the insertion portion 21. [ The lower end of the upper bottleneck portion 28 is connected to the blood extracting unit 50 to be described later. A pair of hook protrusions 22 are symmetrically formed on the outer periphery of the insertion portion 21 and a pair of guide protrusions 23 are symmetrically formed between the pair of hook protrusions 22.

The lower accommodating portion 30 is made of a transparent plastic material having a space for accommodating blood and can observe the inside thereof. The opened lower portion is coupled with the height adjusting portion 60, and the upper bottleneck portion 31 is coupled to the upper accommodating portion 30 Respectively. The lower bottleneck portion 31 is connected to the blood extracting portion 50 to be described later. Supporting walls 32 and 35 are formed on both sides of the upper portion of the lower accommodating portion 30 and accommodating and coupling portions 40 formed in a circular shape are formed above the support walls 32 and 35, respectively. On both sides of the periphery of the receiving and securing portion 40, there is formed a guide groove 43 in which the hook projection 22 is engaged and the hook projection 23 is inserted.

The support wall 35 is composed of a right support wall 32 and a left support wall 35. A magnifying glass 33 is formed at the center of the right support wall 32. A syringe 70 is attached to the left support wall 35, And a needle mounting groove 37 for receiving the needle 75 of the syringe 70 are formed on the upper surface of the syringe 70. The mounting groove 36 is formed in the blood extraction part 50 while passing the inlet 71 of the syringe 70 through the mounting groove 36 as a part where the inlet 71 of the syringe 70 is mounted on the blood extraction part 50. [ When the needle 75 of the syringe 70 is inserted into the mounting groove 36, the syringe 70 is inserted into the mounting groove 36. The needle mounting groove 37 is used to mount the syringe 70 when the needle 75 of the syringe 70 is long and the mounting groove 36 is used when the needle 75 of the syringe 70 is short. The mounting groove 36 is formed at the same height as the center of the blood extracting section 50 in the vertical direction.

The operator can use the syringe 70 in a state in which the position of the PRP 90 is raised during the extraction of the PRP 90 by the extracting user, The height adjusting portion 60 can be adjusted by a hand holding the handle. That is, if there is no mounting groove 36 in the process of extracting the PRP, one hand of the operator will hold the blood separation / extraction container 1 and the other hand will hold the syringe 70. Therefore, in order to operate the height regulating portion 60, the syringe 70 is pulled out from the blood separation and extraction container 1 and placed on a safe place, and the height regulating portion 60 is manipulated by the hand holding the syringe 70, 1, it is troublesome to insert the syringe 70 into the blood extraction unit 50 after adjusting the height of the PRP 90. [ However, in the present invention, since the blood separation and collection container 1 is provided with the mounting groove 36 for receiving the syringe 70, the syringe 70 is placed in the blood separation and extraction container 1, The position of the PRP 90 can be raised by using the height adjusting unit 60 with the hand holding the blood adjusting unit 60 so that the height adjusting unit 60 is operated without removing the syringe 70 from the blood separation / extraction container 1 It is possible to perform the extraction of the PRP 90 again after raising the PRP.

The blood extracting unit 50 is formed of a flexible and transparent silicone material and can observe the inside thereof with a naked eye and has a circular tube shape. The blood extraction part 50 connects the upper storage part 20 and the lower storage part 30. The blood extraction part 50 is formed to have a height larger than the interval between the upper storage part 20 and the lower storage part 30 so that when the upper storage part 20 and the lower storage part 30 are coupled to each other, The extraction portion 50 is engaged while being pressed between the upper accommodating portion 20 and the lower accommodating portion 30. [ The upper end surface 51 and the lower end surface 52 of the blood extracting section 50 are inclined inwardly. The inside of the blood extracting section (50) permits movement of blood as a penetrating structure. When the blood extracting unit 50 is coupled to the upper accommodating unit 20 and the lower accommodating unit 30, the blood extracting unit 50 is deformed and the depressed portion 55 recessed in the outer surface of the blood extracting unit 50 Is formed.

The height adjusting portion 60 is coupled to the lower end of the lower accommodating portion 30. [ The height adjusting portion 60 includes a packing portion 67 screwed to the adjustment bolt 61. When the adjustment bolt 61 is rotated, the packing portion 67 is raised or lowered. Since the packing portion 67 is coupled to the lower end of the lower receiving portion 30, the inner volume of the lower receiving portion 30 is changed when the packing portion 67 is raised or lowered. Referring to the structure of the height adjusting part 60, an adjustment bolt 61 for adjusting the height of the liquid inside the blood separation / extraction container 1 with the user is located at the lowermost part. The adjustment bolt 61 is provided with a snap ring seating portion 63 on which the snap ring 65 can be seated, and the snap ring 65 is seated upon engagement. The snap ring 65 is positioned between the male screw portion 62 and the stationary bracket 64 and functions to fix the male screw portion 62 to the stationary bracket 64. [

And the fixing bracket 64 is fixed to the lower accommodating portion 30. [ When the adjustment bolt 61 is rotated, the fixing bracket 64 guides the adjustment bolt 61 so that it can rotate only without changing its position.

In addition, the female thread portion 66 coupled to the male thread portion 62 of the adjustment bolt 61 is coupled with the packing portion 67 around the threaded portion 66 so that they move together. When the male screw portion 62 whose position is fixed by the fixing bracket 64 is rotated, the male screw portion 62 does not move but can move up and down by moving only the female screw portion 66. Since the female thread portion is tightly coupled to the packing portion 67 tightly and the packing portion 67 is in close contact with the inner side surface of the lower receiving portion 30, when the adjustment bolt 61 is rotated, the female thread portion does not rotate, As shown in FIG. Therefore, in the present invention, the adjustment bolt 61 is rotated to change the volume of the lower accommodating portion 30 by using the packing portion 67 coupled to the female screw portion 66, whereby the PRP 90 To the blood extracting section 50, and extracts the elevated PRP 90 to the syringe 70. In this case,

That is, when the PRP 90 is extracted through the PRP extraction operation for the first time, the height of the PRP 90 relative to the blood extracting unit 50 is lowered. By operating the height regulating unit 60, The PRP is raised by the packing portion 67 pushing up the blood in the lower accommodating portion 30 upward and the PRP rises to the horizontal position again with respect to the blood extracting portion 50.

Hereinafter, a method for binding a blood separation and extraction container according to the present invention will be described.

The lower accommodating portion 30 and the upper accommodating portion 20 are aligned to face the guide protrusions 23 and the guide grooves 43 and then the blood extracting portion 30 is inserted between the lower bottleneck portion 31 and the upper bottleneck portion 28. [ (50). At this time, the upper end of the blood extraction part 50 is adjacent to the lower end of the upper bottleneck part 28, and the lower end of the blood extraction part 50 is adjacent to the upper end of the lower bottleneck part 31.

The guide protrusion 23 of the insertion portion 21 of the upper receiving portion 20 is guided along the guide groove 43 of the receiving and coupling portion 40, The insertion portion 21 is lowered to the inside of the receiving and coupling portion 40 and the hook projection 22 of the insertion portion 21 is inserted into the hook projection engaging portion 41 of the receiving and coupling portion 40 It is fastened while being hooked. When the upper and lower bottleneck portions 28 and 31 are positioned between the upper and lower bottleneck portions 30 and 30, The upper bottleneck portion 28 and the lower bottleneck portion 31 are coupled to the blood extraction portion 50 while the upper and lower bottleneck portions 28 and 31 are fitted and adhered to each other. Since the upper end surface 51 and the lower end surface 52 of the blood extracting unit 50 have a tapered structure inward, the upper and lower ends of the blood extracting unit 50 are divided into the upper and lower bottleneck portions 28, The blood bottles are guided to the inside of the blood extracting unit 50 to induce accurate binding.

The height of the blood extraction part 50 is formed to be larger than the gap between the lower end of the bottleneck portion of the upper accommodating portion 20 and the upper end of the bottleneck of the lower accommodating portion 30, The blood extracting unit 50 is excessively pressed in the vertical direction and is coupled to the upper receiving unit 20 and the lower receiving unit 30. [ When the blood extracting unit 50 is excessively compressed and joined, the upper and lower ends of the blood extracting unit 50 spread outward, and the outer peripheral surface of the blood extracting unit 50 is vertically Thereby forming a depression 55 having a shape in which the central portion of the recess is depressed inward. The depressed portion 55 is formed at the outer surface of the blood extracting portion 50 so that the center of the depressed portion 55 is tilted at its center so that the depressed portion 55 guides the needle 75 of the syringe 70 to the center of the vertical reference It is easy to insert the needle 75 of the syringe 70 into the center of the blood extraction part 50. [ Since the blood extracting unit 50 is pressed and coupled between the upper accommodating unit 20 and the lower accommodating unit 30, The airtightness performance between the electrodes is excellent.

Hereinafter, the operation and effect of the blood separation / extraction container according to the present invention will be described.

FIG. 4 is a cross-sectional view of a blood separation and extraction container according to the present invention, in which a syringe is moved to a blood extraction unit through a mounting groove of a right support wall to infiltrate a needle of a syringe into a blood extraction unit, And the PRP is precisely extracted by the injector while looking at the PRP.

2 and 4, the blood separation and extraction container according to the present invention includes a syringe 70 which is inserted into the blood extraction part 50 through a fixing groove 36 of the right supporting wall 35, The PRP can be extracted by inserting the needles 75 of the left supporting wall 32 and the magnifying glass 33 formed on the left supporting wall 32.

Therefore, the blood extraction container according to the present invention can enlarge and view the blood extracting unit 50 through the magnifying glass 33 formed on the right supporting wall 32. Therefore, even if the PRP layer occupying an extremely small amount The boundary line between the blood components is clearly visible to the naked eye by the image magnified by the magnifying glass 33. [

Therefore, even if the thickness of the PRP layer is reduced in the process of extracting the PRP with the injector 70, it is possible to extract the PRP while looking at the enlarged image through the magnifying glass 33, so that the needle of the injector is accurately located in the PRP layer It is possible to reliably prevent the other components of the blood from being extracted. That is, when the PRP is mostly extracted and only a small amount remains, the PRP can be enlarged through the magnifying glass 33, so that the remaining PRP can be precisely extracted.

FIG. 5 is a view illustrating a state in which PRP is extracted in a process of extracting a PRP using a blood separation and extraction container according to an embodiment of the present invention, and the height of the PRP is elevated by adjusting a height adjuster for extracting additional PRP .

First, blood is injected into the blood separation / extraction container 1 through the plug 10. The air outlet 13 formed in the cap 10 discharges the air inside the blood separation / extraction container 1 during blood injection to facilitate blood injection.

After the blood is injected and the blood separation vessel is rotated through the centrifugal separator, red blood cells are collected at the lowest level of the blood separation extraction vessel (1), a buffy coat containing a part of white blood cells and plasma is formed at the red blood cells, Plasma layer on top. In addition, the plasma is again layered with the PRP (90) at the bottom and the PPP at the top. At this time, in order to extract the PRP 90, the adjustment bolt 61 of the height adjuster 60 is first rotated to change the volume of the lower accommodating portion 30. [ That is, by rotating the adjustment bolt 61, the packing part 67 is raised to place the PRP layer in the blood extraction part 50, and then the PRP 90 is extracted by inserting the syringe 70.

As shown in FIG. 5, after the PRP 90 located in the blood extracting unit 50 is almost completely extracted, the PRP located in the lower accommodating unit 30 must be lifted up again. The needle 75 of the syringe 70 or the front side of the syringe 70 is inserted into the fixing groove 36 of the support wall 35 while the needle 75 of the syringe 70 is inserted into the blood extracting unit 50. [ The PRP located in the lower accommodating portion 30 is removed from the blood extracting portion 60 by rotating the adjusting bolt 61 of the height adjusting portion 60 with the hand of the syringe 70 being released, 50). Then, the PRP located in the blood extracting unit 50 is extracted by the syringe 70 again.

The needle 75 of the syringe 70 is inserted into the blood extraction part 50 of the blood separation and extraction container by forming the syringe 70 mounting groove 36 in the support wall 35 of the lower accommodating part 30, It is not necessary to remove the syringe 70 until all of the extraction is completed.

After extracting a certain amount of blood in the process of extracting a specific part of blood from the blood separation / extraction container, the blood of the lower storage part 30 should be raised upward by rotating the adjustment bolt 61. However, conventionally, in order to return the control bolt of the container, the syringe inserted into the container was pulled out, placed on the tray, and the container was held with one hand and the adjustment bolt was returned with one hand. After returning the adjustment bolt, the needle was inserted into the container again to perform the next extraction operation. However, this method has a possibility to contaminate the needle of the syringe because it is necessary to pull out the needle of the syringe and expose it to the outside.

Also, if you have to do other things suddenly due to unforeseen circumstances during your work, you have to remove the syringe from the container and store the container and syringe in a storage box or tray. Then, when the extraction operation was started again, the needle of the syringe was inserted again in the vessel to perform the extraction operation.

However, in the blood separation and extraction vessel according to the present invention, once the needle 75 of the syringe 70 is inserted for the extraction operation, the needle 75 of the syringe 70 is pulled out from the vessel until the extraction operation is completed You do not have to do. This is because the needle 75 of the syringe 70 or the inlet 71 of the syringe 70 can be inserted into the mounting groove 36 of the support wall 35. [ Even when the adjustment bolt 61 of the container is turned, the adjustment bolt 61 may be turned after the syringe 70 is mounted on the mounting groove 36. In the case where the user needs to perform another operation urgently during the extraction operation, As long as the syringe 70 is placed in the mounting groove 36 and then the container in which the syringe 70 is stuck is directly inserted into the mounting groove 82 of the container storage box 80. Therefore, if the blood separation / extraction container is inserted into the container storage box 80, the blood separation / extraction container can be safely stored without withdrawing the syringe 70 from the blood separation / extraction container.

Since the needle 75 of the syringe 70 is not pulled out from the blood separation and extraction vessel during the operation of extracting the PRP from the blood separation and extraction vessel, the possibility that the needle 75 of the syringe 70 is contaminated on the outside is significantly . Particularly, since PRP extracted from blood is widely used by injecting into the body again, the extracted PRP should be very careful of contamination. The present invention can significantly reduce the possibility of such contamination since the needle 75 of the syringe 70 is not pulled out of the container during the extraction process.

In addition, even when the extraction operation is stopped and then the extraction operation is started again, the need to pull out the needle 75 of the syringe 70 from the container and then insert it into the container again can be omitted, And it becomes convenient.

3) When extracting the blood from the container, the operator extracts the blood while watching the boundary of the eye, so that the boundary of the blood at the extraction point needs to be visually seen. That is, the visibility should be good.

FIG. 6 is a conceptual diagram showing a comparison between the transmission state of light of a conventional blood extraction container and the blood separation extraction container shown in FIG. 1;

As shown in FIG. 6, the blood separation / extraction container according to the present invention includes the blood extraction part 50 between the upper storage part 20 and the lower storage part 30 as a single part. That is, the portion connected between the upper accommodating portion 20 and the lower accommodating portion 30 is connected only by the blood extracting portion 50 made of transparent silicon. Therefore, since the point of extracting the blood of the container is made of only one transparent silicon, optically diffuse reflection or light refraction rarely occurs or is minimized. That is, since it is a single part made of a transparent silicon material, irregular reflection of light and light refraction or diffuse reflection can be minimized.

However, when the blood extraction part is combined with the heterogeneous components, the diffuse reflection or refraction is greatly generated at the boundaries of the heterogeneous material, thereby greatly reducing the visibility of the boundary of the blood layer. For example, in the case of a conventional container as shown in FIG. 6A, since the material of the silicon material 100 and the material of the injection material 101 are different from each other when a silicon material is injected, a diffused reflection of light or a refraction of light Causing deterioration of the visibility of the boundaries of the blood, resulting in difficulty in the extraction operation.

4) FIG. 7 is a conceptual diagram showing the possibility of damage of the conventional blood extraction container and the blood separation and extraction container shown in FIG. 1.

7, the entire connection portion between the upper accommodating portion and the lower accommodating portion may be formed of a silicone material by the insert injection method (FIG. 7A). In this structure, however, the hardness And the possibility of breakage of the connecting portion due to lack of rigidity is high, and as a result, the possibility of blood leakage increases. Silicone is a flexible material, so its rigidity is weak, and it lacks the ability to resist shape and maintain its shape. Therefore, when an external force is generated, the silicon connection portion may be broken or peeled, and damage may easily occur.

The present invention is characterized in that the blood extracting unit 50 as the connecting portion is formed of a pure silicone material so that the mutual coupling of the upper accommodating unit 20 and the lower accommodating unit 30 is performed separately from the blood extracting unit 50 The supporting walls 32 and 35 and the receiving and securing portions 40 are provided. The bonding portion and the support walls 32 and 35 almost all bear the external force applied to the blood separation / extraction container, so that the external force is not directly applied to the blood extraction portion 50 made of silicon. Therefore, the blood extracting unit 50 can be made of a pure silicon material to maintain the structural rigidity of the container while securing excellent visibility.

The reason why the blood extraction part 50 is formed of a transparent silicon material is as follows. The blood is centrifuged and the middle layer is composed of a buffy coat layer consisting of white blood cells and platelets. Since this buffy coat layer is a very small amount of blood, the needle 75 of the syringe 70 can be inserted at a desired point The blood extracting unit 50 is formed of a transparent silicon material.

FIG. 9 is a conceptual diagram showing a state in which the syringe maintains the horizontal position in the blood separation and extraction container of FIG. 1 and a state in which the syringe can not maintain the horizontal position in the conventional container.

9, the blood separation / extraction container according to the present invention is a blood separation / extraction container according to the present invention in which an inlet 71 of a syringe 70 is passed through a fixing groove 36 of a support wall 35, Penetrates into the center of the concave depression 55 at the center of the outer surface of the blood extraction part 50, the level of the needle 75 relative to the blood extraction part 50 is inevitably obtained. After the needle 75 is infiltrated into the blood extracting section 50, the needle 75 is moved horizontally relative to the blood extracting section 50 as long as the inlet 71 of the syringe 70 is not separated from the receiving groove 36 The invasive state continues to be maintained.

As the needle 75 is held horizontally with respect to the blood extracting unit 50, the extraction of the PRP can be accurately performed. That is, when the user extracts the PRP from the container, the PRP is extracted while visually checking the upper and lower boundaries of the PRP layer with the container standing upright. At this time, the needle 75 is horizontally Only the component of the PRP layer can be accurately extracted.

If the needle of the syringe is obliquely inserted into the blood extracting part as shown in FIG. 9B, there is a risk that components other than the PRP layer are extracted. This is because once the needle of the syringe is infiltrated into the blood extraction part, it is difficult to visually confirm the exact position of the end of the needle. However, when the needle 75 is horizontal with respect to the blood extracting unit 50, even if the tip of the needle 75 is not visible to the naked eye, the position of the end of the needle 75 may be shifted to a position on the inserted height line of the blood extracting unit 50 As a result, the exact position of the tip of the needle 75 can be known. However, as shown in FIG. 9B, when the needle is inclined to the blood extracting unit, the tip of the needle is not visible visually, so that the exact position of the tip of the needle can not be known. Therefore, it is difficult to extract PRP precisely from the blood.

6) In addition, since the upper receiving portion 20 and the lower receiving portion 30 are formed as independent structures to each other to form a container, the blood extracting portion 50 is interposed between the upper receiving portion 20 and the lower receiving portion 30 When the upper and lower receiving portions 20 and 30 are coupled together, the blood extracting portion 50 is automatically coupled in the process of coupling the upper receiving portion 20 and the lower receiving portion 30. If the upper receiving portion and the lower receiving portion are integrally formed, it becomes very difficult to join the blood extracting portion between the upper receiving portion and the lower receiving portion, and it is difficult to increase airtightness. That is, as the blood extracting unit 50 is coupled in an excessively compressed state, the airtightness between the blood extracting unit 50 and the upper accommodating unit 20 (or the lower accommodating unit 30) will be improved. However, It is very difficult to allow the blood extracting unit 50 to be squeezed in the lateral direction between the upper accommodating unit 20 and the lower accommodating unit 30 while the blood extracting unit 50 is excessively compressed. However, according to the present invention, since the blood extracting unit 50 is naturally compressed during the process of coupling the upper receiving unit 20 and the lower receiving unit 30, the blood extracting unit 50 can be easily coupled In addition, excellent airtightness due to excessive compression can be obtained. In addition, since both ends of the blood extraction part 50 are tapered downward inward, the ends of the receiving parts can be easily inserted into the blood extraction part 50.

7) The blood separation and extraction vessel 1 according to the present invention can accurately extract PRP 90 by a desired amount. Among the components of blood separated by centrifugation, erythrocytes are located in the lower part of the vessel, and buffy coat and plasma are sequentially placed thereon. Plasma is separated into PRP (90) and PPP. Conventional blood separation and extraction vessels do not have a means for precisely guiding the position of the needle of the syringe and place the needle of the syringe depending on the operator's senses. Therefore, when the needle of the syringe is misplaced, sometimes the red blood cells Could occur. In addition, the position of the syringe needle may be changed due to trembling of the operator's hand or the like. However, since the blood separation and extraction container 1 according to the present invention horizontally guides the syringe 70 through the fixing groove 36 in the lateral direction of the blood extraction part 50, Since the needle groove 75 is easily inserted and the needle groove 75 of the syringe 70 is inserted into the blood extracting section 50, since the holder groove 36 supports the syringe 70, The needle 75 of the syringe 70 can be held in a stable and precise position in comparison with the situation in which the syringe is held by hand in the absence of the needle. Therefore, the needle 75 of the syringe 70 can be accurately positioned horizontally at an intended position of the blood extracting unit 50, and it is easy to maintain the position of the needle 75 in comparison with the conventional blood separation / extraction container. ) Can be accurately extracted by a desired amount.

In the above embodiment of the present invention, PRP is extracted from blood components through a blood separation and extraction container. However, the present invention is not limited to extracting PRP components from blood components, But it can be used to extract other specific components. Therefore, the scope of right of the present invention is not limited to extracting only PRP of blood.

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 embodiments, but, on the contrary, And additions should be considered as falling within the scope of the claims of the present invention.
