Traditionally, whole blood was often used in blood transfusions, but
Recently, with advances in medical care, a therapeutic method called component transfusion, in which only the necessary components are transfused, is being promoted both domestically and internationally. However, in red blood cell component transfusion, HL-
Red blood cell transfusions are not always performed frequently because there is no good way to completely remove leukocytes with type A antigens and platelets with platelet antigens. Also, in a biochemical function test of red blood cells, the presence of other blood cell components does not yield good results.

4, 1973] used cation-exchanged cellulose or cation-exchanged Sephadex to purify red blood cells from a heparinized solution, but ion exchangers were expensive and magnesium ions were not available. Moreover, it has drawbacks such as the amount of adsorbent being large relative to the amount of blood, making it impractical. On the other hand, Wright [The Lancet]
Lancet) + Vol. 1, p. 4, 1926] found that white blood cells adsorbed to filter paper, but Garvin (Journal of Experimental Medicine)
xperlmentalMediaine) s 1
Vol. 14, p. 51, 1961] states that adsorption to filter paper is not very large. In view of the above circumstances, the present inventor conducted intensive research and found that cellulose powder and crystals can be extracted from human whole blood, red blood cell flow layer, and mammalian blood. They succeeded in recovering red blood cells with high purity and high yield by almost completely adhering white blood cells and platelets to cellulose and anion-exchanged cellulose, and completed the present invention. The configuration achieved is a blood fractionation/purification device having a column and an adsorbent in the column, the column has a blood inlet and a blood outlet, and the column contains cellulose powder, crystalline cellulose, anion exchanger, etc. A device for fractionating and purifying blood, characterized in that it is filled with an adsorbent made of at least one of cellulose and is further provided with a mesh that supports the adsorbent.

In carrying out the present invention, the adsorbent is supported by a mesh having an opening of about 25 microns, such as a nylon mesh, in a column made of a hard plastic snack made of polypropylene, etc., and the adsorbent is filled into the column with physiological saline. Pour in the KWIA cloudy adsorbent, pressurize if necessary, and pack at a rate of 2 to 6 td/19. The amount of adsorbent is blood 1
It ranges from 10-50- to 00-. Washing after passing blood through the adsorbent is recommended to increase the recovery rate of red blood cells, and the washing solution should be physiological saline.

The appropriate amount of physiological saline for washing is 1 to 3 to 1 of the adsorbent.The time for passing through the column is 5 to 120 minutes, and if the flow rate is slow, apply with a force of IV4/- or less. As shown in Examples 1 to 5 below, as a result of fractionating red blood cells from human whole blood, red blood cell flow layer, and mammalian blood by the method of the present invention, the recovery of red blood cells Results showed that the removal rate of white blood cells was over 95%, and the removal rate of platelets was over 99%. When the recovered red blood cells were observed under a scanning electron microscope, they showed exactly the same disk shape as before contact with the adsorbent, and when viewed by Perpart's method in terms of osmotic fragility, there was no change at all before and after contact with the adsorbent. In addition, after storing the samples that were in contact with the adsorbent and those that were not in contact with the adsorbent for one week at 4°C, we determined the quantitative determination of adenosine triphosphate and 2,3-diphosphoglycenic acid, and found that there was no difference in the quantitative values. It wasn't accepted.

As an apparatus for implementing the method of the present invention, there is an apparatus as shown in FIG. 1, in which a blood bag 1 is connected to a column 3 filled with an adsorbent 5 and supported by a nylon mesh 4. used. Blood products such as human whole blood or a red blood cell flow bed are guided from a hollow needle 7 through a conduit 2 to a column 3 filled with an adsorbent 5, and white blood cells and platelets adhere to the adsorbent 5. Red blood cells that do not adhere to the adsorbent 5 are collected into the blood bag 1 through the conduit 2. Additionally, this device can be sterilized by autoclaving at 115° C. for 15 minutes. The only substance that is affected by this heat treatment is diethylaminoethylcellulose, which is an m-ion exchanger, and other celluloses are not affected by this treatment.
