Multifunctional apparatus for treatment of renal insufficiency

Multifunctional apparatus for treatment of renal insufficiency

Multipurpose appts for extracorporeal blood circulation and treatment The blood treatment device includes an exchanger (1) with two chambers (2, 3) separated by a membrane (4). The first chamber (2) is connected to a pump (6) via ducts (5, 7). A bubble trap (8) is provided in the circuit. The ducts have needles at their extremity which are inserted into a patient vein. A dialysis liquid tank (10) is connected to a second pump (12) via a duct (11) which runs to the second chamber of the exchanger. Electromagnetic clips (15, 16) are provided for connecting the tank to either the kidney chambers or to the blood circuit. Used liquid is eliminated via a duct (18) and a pump (19) into a second tank (17). The bubble trap is linked to a tank (20) containing a solution of bicarbonate.

Technique for extracorporeal treatment of blood

A method for priming a circuit for multiple blood extracorporeal treatments, the circuit comprising : a filtration unit (40) having a primary and a secondary chamber (44, 46) separated by a semipermeable membrane (42) ; a primary circuit comprising a blood access line (34) connected to an inlet of the primary chamber (44) and a blood return line (35) connected to an outlet of the primary chamber (44) ; a collection fluid line (82) connected to the outlet of the secondary chamber (46) the method comprising the steps of : circulating a priming fluid from an end of the blood return line (35) to an end of the blood access line (34) and through the primary chamber (44) for a predetermined priming time ; and when the primary circuit (34, 35) is filled with priming fluid, ultrafiltering priming fluid from the primary chamber (44) into the secondary chamber (46) and circulating priming liquid from the secondary chamber (46) to an end of the collection fluid line (82).
