Plasmaseparations- und Plasmasammelvorrichtung von Single-Needle-Typ.

摘要

The single-needle type plasma separation apparatus (1) of the present invention comprises a blood collection needle (21); a blood collection container (5); a first blood transportation tube (2) connecting the blood collection needle (21) to the blood collection container (5); a blood separator (7); a second blood transportation tube (6) connecting the blood collection container (5) to a blood inlet (7a) of the blood separator (7); a third blood transportation tube (8) connecting a blood outlet (7b) of the blood separator (7) to the first blood transportation tube (2); a plasma collection container (10); a plasma transportation tube (9) connecting a plasma outlet (7c) of the plasma separator (7) to the plasma collection container (10); and a blood collection container receptacle (18) including a receiving portion for the blood collection container (5) and capable of pressurizing and depressurizing the interior of the receiving portion. Because the single-needle type plasma separation apparatus (1) of the present invention is provided with the blood collection container receptacle (18) including the receiving portion for the blood collection container (5) and capable of pressurizing and depressurizing the interior of the receiving portion, it is possible to carry out the collection of blood into the blood collection container (5), the transportation of the collected blood to the plasma separator (7), and the return of the concentrated red blood cells from the plasma separator (7). Therefore, the present invention affords the advantages that the circuit construction is simple, the whole size of the apparatus is small, the apparatus can be used even in a narrow car for blood donation because there is no necessity for ensuring a head for circulating blood through a plasma separator, parts to be handled can be gathered, improving the operability, and plasma can easily be collected. Furthermore, the blood transportation tubes connecting the components to one another can be shortened, the volume for priming of the plasma separation apparatus can be made small, and an automation of the operation becomes possible.
