ABSTRACT:
A blood transfusion device has at least one blood accelerating pump, a variable volume reservoir, at least one single-use blood supply bag, a platen, a blood reheater, a single-use blood reheater bag, a filtration system and a perfusion line. The variable volume reservoir varies in volume using an accordion-like bellows or a flexible pocket acted upon by the blood accelerating pump. The single-use blood supply bag contains concentrated corpuscles, plasma, or a solution of albumin. The blood supply bag is disposed between two plates precisely spaced apart. The platen is acted upon by the accordion-like bellows or the flexible pocket to slide in parallel to the two plates, and is disposed between the variable volume reservoir and the blood supply bag. The blood reheater includes an assembly of two double plates, each double plate having a preheating plate heated to a constant temperature slightly less than 38.degree., and a heating plate heated to a variable volume controlled by a temperature detector at an outlet of the blood transfusion apparatus. The single-use blood reheater bag is disposed between each of the two double plates and communicates, via an inlet member, with the single-use blood supply bag. The filtration system is disposed at an outlet of the blood transfusion apparatus, and the perfusion line is connected to an outlet of the filtration system by conical couplings, and is terminated in a trocar.
