Embodiment Construction

[0043] Hereinafter, the blood bag system and the tube holder according to the present invention will be described by citing preferred embodiments with reference to the drawings.

[0044] figure 1 It is a schematic diagram showing the overall structure of the blood bag system 10 according to one embodiment of the present invention. The blood bag system 10 is to centrifuge blood containing multiple components into three components of light specific gravity, medium specific gravity and heavy specific gravity (in this embodiment, whole blood is centrifuged into plasma, buffy coat (BC ) and three components of concentrated red blood cells), a system that separates, accommodates, and stores each component in different bags. Such as figure 1 As shown, the blood bag system 10 includes a plurality of bags (first to fourth bags 11 to 14 ) and a plurality of delivery tubes (first to fourth delivery tubes 21 to 24 ).

[0045] Each of the first to fourth bags 11 to 14 is, for example, l...

Abstract

The invention aims to prevent or suppress a blood component from being unnecessarily mixed to other bags by returning blood moved to a tube from a bag before centrifuge to the bag during the centrifuge. A blood bag system (10) has a cassette (50) (tube holder) for holding at least a part of the first transfer tube (21). The cassette (50) holds the first transfer tube (21) such that a distance between a rotation center (O) in application of a centrifugal force and the first transfer tube (21) increases toward the blood collection bag (11) side across a length between a flow path close position caused by the first clamp (71) in the first transfer tube (21) and the blood collection bag (11).

Description

technical field [0001] The present invention relates to a blood bag system configured to transport whole blood or centrifuged blood components out of the bag via a tube held in a tube holder, and a tube holder applicable to such a blood bag system. Background technique [0002] In recent years, at the time of blood transfusion, components of blood (whole blood) obtained by donating blood or the like are separated to provide only required components to patients. Through blood component transfusion, not only the burden and side effects on the circulatory system can be reduced for the patient, but also the donated blood can be effectively used. [0003] In the separation of blood components, for example, a blood bag system including a plurality of bags and a plurality of tubes is mounted on a centrifuge transfer device as disclosed in Patent Document 1 below. Subsequently, it is centrifuged by a centrifuge delivery device into: a light supernatant PPP (platelet poor plasma) fr...
