Problems solved by technology

Compared with autoclave sterilization, EOG sterilization has problems such as requiring a lot of labor and high cost due to the need for special processing gases and other reasons.
In addition, conventional boxes have been molded using mass injection molding, leading to problems such as high manufacturing costs

no. 1 approach

[0050] figure 1 Among them, the blood component sampling system 10A is configured as a blood apheresis system that continuously draws blood (whole blood) from a blood donor and centrifuges the blood outside the body, thereby collecting specific blood components (this embodiment In the way of platelets, red blood cells, plasma), at the same time, the blood components that were not sampled were transfused back to the blood donor.

[0051] first of all, yes figure 1 The illustrated blood component sampling system 10A is briefly described. This blood component sampling system 10A includes a blood collection circuit set 12 configured to store and circulate blood components, and a centrifuge 14 (blood component separation device) configured to apply centrifugal force to the blood collection circuit set 12 . The blood collection circuit set 12 has a channel 17 (blood processing part) as a primary separator configured to introduce and centrifugally separate whole blood drawn from a ...

no. 2 approach

[0144] Next, the main Figure 15 Differences between the illustrated blood component sampling system 10B of the second embodiment of the present invention and the blood component sampling system 10A of the first embodiment will be described. This blood component sampling system 10B comprises: a blood collection circuit set 12a, which includes a blood component sampling box 22a (hereinafter referred to as "box 22a"); and a centrifuge 14a (see Figure 16 ).

[0145]The blood collection circuit set 12a includes a cartridge main body 23a provided with a plurality of flow paths, and the cartridge main body 23a is joined so that the first sheet 38 and the second sheet 39 overlap each other in the thickness direction to form a plurality of flow paths. The plurality of flow paths of the cartridge body 23 a include an introduction line 42 , a blood component delivery line 43 , a blood return line 44 , and an ACD solution line 45 similarly to the plurality of flow paths of the cartridg...

Abstract

A blood component sampling cassette which can be more efficiently manufactured at lower cost as compared to a typical cassette, a blood sampling circuit set, and a blood component sampling system. A blood component sampling cassette (22) includes a cassette main body (23) made of a soft material to which heat sterilization is applicable. The cassette main body (23) is provided with a retransfusionline (44). The retransfusion line (44) is provided with a reservoir (47) configured to temporarily store a blood component to be returned to a blood donor. The reservoir (47) is pressed by a retransfusion pump (49) to discharge the blood component from the reservoir (47).

Description

technical field [0001] The present invention relates to a biological component sampling cartridge mounted to a separation device configured to separate a biological component from a liquid containing at least one biological component. Specifically, the present invention relates to a blood component sampling cartridge, a blood sampling circuit kit, and a blood component sampling system mounted on a blood component separation device. Background technique [0002] In blood donation in recent years, in addition to whole blood sampling in which whole blood is collected from a blood donor, blood component sampling (apheresis) that places less burden on the body of the blood donor is also performed. Blood component sampling is a blood collection method that uses a blood component sampling system (apheresis system) to collect only specific blood components from whole blood and return the remaining components to the blood donor. [0003] Patent Document 1 discloses a blood component...
