FIELD: medicine. ^ SUBSTANCE: invention refers to medicine, particularly blood separation apparatuses. The apparatus comprises blood sampling and erythromass return branches 1, 2 equipped with catheters 6, a plasmafilter attached between the branches 1, 2, 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 12 and a gate valve 17. In the blood branch 1, the blood pump follows and precedes pressure sensors 10, 11. In the plasma drainage branch, the plasmafilter 7 is followed with an optical sensor 18 of plasmafilter blood leakage, a plasma pump 19 with a pressure sensor 20 and a plasma container 21. The saline feed branch from a salne container through an auxiliary pump and a saline detector is connected to the blood branch between the blood pump and plasmafilter or directly to the air trap 12. The anticoagulant feed branch connects the blood branch following the catheter through an anticoagulant pump and a citrate detector to an anticoagulant container. The air trap is equipped with a blood level detector 13 and an adjusting valve. The erythromass return branch following the air trap has a pocket air detector. ^ EFFECT: provided self-regulation and safety parametres checkout. ^ 2 cl, 3 dwg |
