SINGLE-NEEDLE PLASMAPHERESIS APPARATUS Russian patent published in 2011 - IPC A61M1/34 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, particularly blood separation apparatuses. The apparatus comprises a blood sampling branch 1 and an erythromass return branch 2 with their free ends T-jointed with a catheter, a plasmafilter attached between said branches, a plasma drainage branch 3 and saline and anticoagulant feed branches 4,5. The blood sampling branch 1 is equipped with a gate valve 8 and a blood pump 9, while the erythromass return branch 2 accommodates an air trap 14 and a gate valve 19. In the blood branch, the pump is followed with a storage container 10 with a container weight recording element 11 and a blood pump 12 with a pressure sensor 13. The plasma drainage branch 3 following the plasmafilter 7 is supplied with an optical sensor 20 of plasmafilter blood leakage, a plasma pump 21 with a pressure sensor 22 and a plasma container 23; the saline feed branch 4 connects the blood branch between the gate valve and the blood pump through a supplementary pressure sensor, a gate valve and a saline detector with a saline container. The anticoagulant feed branch 5 connects the blood branch 1 blood to the gate valve 8 through an anticoagulant pump 28 and a citrate detector 29 with an anticoagulant container 30. The air trap 14 is equipped with a blood level detector and an adjusting valve, and the erythromass return branch following the air trap has a pocket air detector 18.
