Abstract:
Blood transfusion apparatus comprising:at least one compression pump comprising a pump outlet;a reservoir of variable volume which varies in volume by means of an accordion-like bellows acted upon by said at least one compression pump, said reservoir being connected to said pump outlet;at least one single-use blood supply bag for containing one of concentrated corpuscles, plasma and a solution of albumin, said at least one blood supply bag comprising an outlet and being disposed between two surfaces precisely spaced apart;a pressure plate pushed or retracted by said accordion-like bellows so as to remain parallel to said two surfaces, said pressure plate being disposed between said variable volume reservoir and said at least one blood supply bag;a blood reheater comprising an assembly of two double plates, each double plate comprising a preheating plate heated to a constant temperature slightly less than 38.degree. C., and a heating plate heated to a variable temperature controlled by a temperature detector;a single use blood reheater bag disposed between each of said two double plates, said single use blood reheater bag communicating, via an inlet member, with said at least one single use blood supply bag outlet;a filtration system having an inlet and an outlet, said inlet being disposed at an outlet of said blood reheater bag, said filtration system further comprising the temperature detector; anda perfusion line connected to said outlet of said filtration system by conical couplings and terminated in a trocar.
