In particular, the blood can be used for various medical purposes, such as transfusion of surgical patients, clinical trials of patients, and as a raw material for various medical drugs. The blood may be used as it is, but specific target substances may be collected and used from the blood. For example, platelets (blood platelet) is a type of blood cell that is a tangible component of the blood, is involved in blood coagulation or hemostatic action, and is easily used during surgery.

On the other hand, in order to collect the desired target substance from the blood, a centrifugation method is generally used. For centrifugation, the blood is centrifuged in a centrifugal separator in a state in which a container for centrifugation is placed. The blood may be a test tube or petri dish having a certain shape, but may be contained in a flexible centrifuge bag and centrifuged.

Centrifugal bags generally include an inlet formed at the top and an outlet formed at the bottom. However, when blood is accommodated in a centrifuge bag made of a flexible material and centrifuged, when a high pressure is applied to the centrifuge bag, a substance may leak out of the centrifuge bag through the outlet.

In addition, the swing-out centrifugal separator includes a rotating bucket coupled to a rotating shaft rotating at a high speed, and may include an adapter inserted into the rotating bucket while the centrifugal bag is fixed. have. However, the centrifugal bag made of a flexible material may be crushed in the rotating bucket during centrifugation to cause the material inside the centrifuge bag to be mixed during centrifugation.

In addition, in the conventional centrifugal separator, after centrifugation, the centrifugal bag must be separated from the adapter to discharge the target material collected at the bottom of the centrifugal bag. It may happen that the materials inside are mixed.

The present invention is a centrifugal separation method, a centrifugal separator, which can prevent the surrounding of the discharge port of the centrifuge bag from being damaged by high pressure or leak the target material through the discharge port in the process of obtaining the target material from the target material through centrifugation.

In the state where the centrifugation space is divided, the target substance can be discharged from the outlet, and only the target substance can be easily collected through the outlet.

The division of the centrifugal space may be implemented by externally pressing the front and rear portions of the separation bag, and the discharge of the target substance may be performed in a state in which the centrifugal space and the outlet are physically separated. Similarly, the process of physically separating the centrifugal space and the discharge port may be implemented by externally pressing the front and rear portions of the separation bag.

More specifically, when the adapter body corresponding to the rotating bucket for centrifugation is used, the centrifugal space and the outlet are physically separated using the first pressing member mounted to the adapter body, while the rotating bucket rotates. The target material can be prevented from leaking from the outlet, the second pressurizing member mounted on the adapter body can be used to divide the centrifuge space, and the mixing with other materials can be prevented during the discharge of the target material after centrifugation. have.

In some cases, the centrifugal space may be physically separated from the outlet by using the first pressing member, and after the centrifugal separation, the centrifugal space may be divided by moving the first pressing member. In this case, the first pressing member may naturally release the state in which the centrifugal space and the outlet are physically separated. For reference, the first pressing member may be provided to slide and fix up and down along the adapter body.

In addition, the pressure member may pressurize the region between the centrifuge space and the outlet to physically separate the centrifuge space and the outlet, and in some cases, the pressure member selectively separates the region between the target material and the separation material after centrifugation. You can also

The pressing member can be fixed to the adapter body in a different position up and down, is fixed in a position to prevent leakage from the discharge port while the rotating bucket is rotated, and prevents mixing with other materials while discharging the target substance after centrifugation It can be fixed in position to physically separate the separation bag. In such a case, the pressing member may be provided to be able to release, slide, and fix the fixed state with respect to the adapter body.

The adapter body may specifically include an upper adapter body member and a lower adapter body member that overlap each other to form a bag receiving space therein, wherein the upper adapter body member may selectively expose the lower adapter body member to expose the bag receiving space. For example, the upper adapter body member may be hinged laterally with the lower adapter body member.

In addition, the lower adapter body member is formed with a body binding portion, the pressing member may include a pressing bar provided in the form of a bar, and the pressing member binding portion that is bound to the body binding portion to bind the pressing bar to the lower adapter body member.

In addition, the upper adapter body member may include an exposure ball for exposing the bag receiving space, in this case, the pressure bar may be bindable to the lower adapter body through the exposure ball.

In addition, the lower adapter body member may include a support bar that protrudes from the inner surface of the lower adapter body and supports the separation bag pressed by the pressure bar at the bottom.

In addition, the bottom of the adapter body may be formed to be recessed around the outlet of the separating bag.

In addition, the upper fixing part and the lower fixing part may be formed inside the upper adapter body member and the lower adapter body member to be coupled to each other to respectively press the edges of the separating bag to fix the separating bag.

According to another exemplary embodiment of the present invention for achieving the above object of the present invention, the centrifugal bag used in the centrifugal separator described above is formed by fusing at least one synthetic resin film formed using a synthetic resin A bag providing an inlet located in the upper portion, an upper separation space in communication with the injection hole, a lower separation space having a narrower width than the upper separation space, and a discharge opening for discharging the target material collected in the lower separation space; Body; A fusion formed around the body of the bag by fusion of the synthetic resin film and formed along the shape of the adapter body to be fixed by the adapter body; And a pressing member mounting hole formed on both sides of the lower separation space to allow the pressing member to be mounted.

The fusion portion is fixed to the adapter body so that it is not easily distorted at the time of centrifugation, and the bottom of the upper separation space and the sides of the lower separation space may have a narrow structure toward the outlet. Through this structure, a jaw does not occur between the upper separation space and the lower separation space, and the accumulation of the target material on the jaw can be effectively prevented.

In addition, the side of the lower separation space may have a structure that narrows and forms an inclined angle that is relatively sharper than the bottom of the upper separation space.

The bottom of the upper separation space is preferably formed to form an inclination angle of 15 to 85 degrees with respect to the horizontal.

In addition, one or two or more of the pressing member mounting holes may be symmetrically formed on both sides of the lower separation space. When forming two or more pressing member mounting holes, it is possible to form a bridge fusion portion which is connected to the outermost fusion portion along the edge of the fusion portion to the side of the lower separation space, and the bridge fusion portion formed between the mounting holes is lower in the separation bag body. It can serve as a support structure for supporting the sides of the separation space.

The fusion portion of the pressure member mounting hole adjacent to the discharge port can be formed in a relatively wider width than the periphery of other pressure member mounting holes, and in this case, when fixed by the upper and lower adapter body members, it can be stably fixed.

For reference, the centrifugal bag is preferably formed using a synthetic resin so that its shape can be flexibly changed when the target material is introduced into the centrifuge space therein. For example, synthetic resins may use polyvinyl chloride or polymers of dimethylsiloxane and polycarbonate. In particular, synthetic resins, such as polyvinyl chloride, have no absorption but elasticity and resistance to chemicals. Other materials may be used.

The bag body may be formed by fusing at least one sheet of synthetic resin film formed using the above-described synthetic resin, and sealing the edges of the separating bag except the inlet and the outlet by welding.

By using a relatively low cost synthetic resin, it is possible to reduce the manufacturing cost of the centrifugal bag, and thus it is possible to use the centrifugal bag for single use. In addition, it is possible to extract purer target cells using the centrifuge bag only once.

The centrifugal separation method, the centrifugal separator, and the centrifugal bag of the present invention physically separate the centrifuge space and the outlet by using a pressure member, thereby accommodating the target material in the process of obtaining the target cells from the target material through centrifugation. It is possible to prevent the surroundings of the outlet of one centrifugal bag from being damaged by high pressure or to leak the target material through the outlet.

The centrifugal separation method, the centrifugal separator, and the centrifugal bag of the present invention are fixed to the centrifugal bag by the adapter body to prevent the centrifugal bag from crushing during the centrifugal separation process, and thus the material inside the centrifugal bag It can prevent mixing.

The centrifugal separation method, the centrifugal separator, and the centrifugal bag of the present invention provide a pressure member directly to the adapter body without installing the centrifugal bag, and immediately after centrifugation without separating the centrifugal bag from the adapter. Allow collection of the desired material. Thus, in the process of separating the centrifuge bag from the adapter after centrifugation, it is possible to prevent the material inside the centrifuge bag from being mixed.

The centrifugal bag of the present invention uses a relatively inexpensive synthetic resin, and furthermore, by fusion welding the synthetic resin film simply, the manufacturing cost of the centrifugal bag is reduced.

It may be formed to become narrower, specifically, the lower side and the lower side of the lower separation space 103 of the upper separation space 102 connected to the lower separation space 103 may be formed to have a different inclination angle. In general, the lower separation space 103 may be fused in an inclined U-shape or may be fused in a more urgently inclined V-shape. If the receiving space inside the body 110 becomes too small, on the contrary, if the bottom of the upper separating space 102 is formed to be horizontal or too slanted, material movement from the upper separating space 102 to the lower separating space 103 is smooth. You may not. Therefore, the bottom of the upper separation space 102 is preferably manufactured to have an inclined angle θ of 15 degrees to 85 degrees.
