Patent number: 10195319Abstract: An object of the invention is to provide a blood component separation device that can keep the concentration of anticoagulant in a predetermined blood component to a constant level to minimize aggregation of a predetermined blood component (for example, aggregation of platelets). One aspect of the present invention is a blood component separation device that separates the predetermined blood component from the blood drawn from a blood donor while supplying to the blood an anticoagulant for preventing coagulation of the blood, where an anticoagulant ratio, or a ratio of an amount of the anticoagulant supplied in relation to the blood, is set according to a hematocrit value of the blood donor so that a concentration of the anticoagulant in the predetermined blood component becomes a predetermined value.Type: GrantFiled: March 6, 2015Date of Patent: February 5, 2019Assignee: Terumo Kabushiki KaishaInventor: Shigeyuki Kimura

Patent number: 10112003Abstract: A blood component separation device includes a centrifuge bowl for separating a blood component from blood, a plasma bag for storing a plasma component, a platelet intermediate bag for storing high-concentration platelet liquid having high-concentration of platelets, and a temporary storage bag (also used as a buffy coat bag) for storing low-concentration platelet liquid having low-concentration of platelets. The blood component separation device performs control, from the second cycle onward, to mix the low-concentration platelet liquid stored in the temporary storage bag in the immediately preceding cycle with whole blood to supply the mixed liquid to the centrifuge bowl. An amount of high-concentration platelet liquid to be collected in the platelet intermediate bag in the first cycle is set to be smallest among all cycles, and an amount of high-concentration platelet liquid to be collected in a last cycle is set to be greatest among all the cycles.Type: GrantFiled: April 26, 2017Date of Patent: October 30, 2018Assignee: Terumo Kabushiki KaishaInventor: Shigeyuki Kimura
