Transfusion and perfusion device for drip and/or emergency intervention

Device for intravenous and intra-arterial transfusion and perfusion securable to a subject and operating in closed circuit, comprising two pressure pockets communicating via a calibrated adjustable expansion valve, each pressure pocket being comprised of a balloon contained in an envelope, each said balloon being stretchable and inflatable and of the same shape as its envelope;

• one of the balloons functioning as a pressure balloon, and the other balloon functioning as a pressing balloon, said pressure balloon continuously supplying the pressing balloon, an inflation bulb for inflating the pressure balloon, an adjustable calibrated expansion valve for regulating fluid under pressure contained in the pressing balloon to a pressure of 100 millibars, a verticalization device for ensuring a vertical drip, each of said envelopes having a sleeve of unstretchable material adapted to receive a flexible pouch of product to be perfused, whereby the pressure balloon contained in its envelope can be inflated either to a high pressure and thus serve as a power pressing balloon to ensure the flow necessary for lifesaving, or as a pressure reserve for regulated pressure for the other pressing balloon contained in the other envelope.
