Embodiment 1

[0051] The system configuration of the blood component separation device of Example 1 is shown in figure 1 . figure 2 It is a block diagram showing a control system of the blood component separation device according to the embodiment.

[0052]The blood component separation device according to this embodiment includes a blood component separation circuit 1 . The blood component separation circuit 1 has an initial blood collection circuit 5, and the initial blood collection circuit 5 includes: a blood collection needle 2, an initial blood collection bag Y7 for collecting initial blood, a sampling port (sampling port) 3, and an initial blood collection circuit 4 .

[0053] In addition, the blood component separation circuit 1 has a centrifuge bowl E1. The centrifuge bowl E1 has a rotor (not shown) having a blood storage space inside the collection, a rotary drive mechanism 14 for rotationally driving the rotor, an inflow port (first port E1a) and an outflow port (second port ...

Embodiment 2

[0125] Next, Example 2 will be described, but the same symbols will be attached to the same components as those in Example 1, and description will be omitted, and the description will focus on differences. The blood component separation device of Example 2 differs from the blood component separation device of Example 1 mainly in that BC recovery (recycle) is not used. Here, the system configuration of the blood component separation device of Example 2 is shown in Figure 22 . The main difference between the blood component separation circuit 30 of the second embodiment and the first embodiment is that it does not have the temporary storage bag Y2.

[0126] Therefore, the operation of the blood component separator of the second embodiment will be described. here, Figure 23 is a flowchart showing the operation of the blood component separation device, Figure 24 ~ Figure 26 The function and process of the blood component separation device are shown.

[0127] For the blood ...

Abstract

The purpose of the present application is to provide a blood component separation device wherein the occurrence of aggregation of predetermined blood components (for example, aggregation of platelets) in a storage bag for storing the predetermined blood components is prevented. To this end, an embodiment of the present invention is a blood component separation device provided with a centrifuge for separating predetermined blood components from blood, and a storage bag for storing the centrifuged predetermined blood components, wherein a predetermined amount of preservative solution is injected into the storage bag in a state before the predetermined blood components are stored therein.

Description

technical field [0001] This invention relates to a blood component separation device including a centrifuge for separating a predetermined blood component from blood and a container for storing the centrifuged predetermined blood component. Background technique [0002] Conventionally, component blood collection in which only platelets and the like are collected and other components are returned to the blood donor has been mainly performed in blood collection. In this case, a blood component separator having a centrifugal separator is used. [0003] In recent years, blood transfusion of platelet fluid has been widely performed in radiotherapy for cancer, etc., and in this case, high-concentration platelet fluid is required. In order to collect high-concentration platelet fluid, the technique of Patent Document 1 is carried out as follows: In the blood component separation device, low-concentration platelet fluid is temporarily stored in a buffy coat bag, and only high-concen...
