Recovery Method blood, hemo-bag system of the blood and lung machine.

Machine cardiopulmonary bypass (100) of claim 10, characterized in that the hemo-bag system (200) comprises a sterile bag (218) closed substantially transparent biocompatible material, defining upper and lower ends (202, 204); an infusion port (210) at the upper end (202) of the bag (218); an output port (220) at the lower end (204) of the bag (218); an input port (235) at the lower end (204) of the bag (218); and IV (240) at the lower end (204) of the bag (218). 12. The machine of cardiopulmonary bypass (100) of claim 10, wherein the bag (218) includes an internal baffle (236) to direct fluid flow upwardly into the bag (218) through the port input (235) during said recirculation, away from the outlet port (220). 13. The machine of cardiopulmonary bypass (100) of claim 10, wherein the bag (218) has a character (206) for indicating a scale of volume gradations of fluid in the bag (218). 14. The machine of cardiopulmonary bypass (100) of claim 10, characterized in that it is adapted during said recirculation that the infusion port (210) and IV (240) are closed; a portion of the track (310, 3112) is connected from the output port (220) of the bag (218) through the pump to the inlet (306) of the hemo-concentrator (302); and a line (304) is connected from the output of hemoconcentrator (302) to the input port (236) of the bag (218) to form a closed recirculation path. 15. A method of operating a machine (100) providing an extracorporeal circuit with respect to a blood circuit of the patient, the extracorporeal circuit in which has at least one pump (106, 122, 138, 146), wherein the method comprises circulating the patient's blood after the machine has been disconnected from the patient (10), further comprising forming a fluid circuit including at least one pump (106, 122, 138, 146), with a pipe system from at least one pump (106, 122, 138, 146) to the input (306) of the hemo-concentrator (302), pipe systems from the outlet of the hemo-concentrator (302) to the system hemo-bag (200) and tube system from the hemo-bag system (200) to at least one pump (106, 122, 138, 146) and operating at least one pump (106, 122, 138, 146) for circulating fluid through said circuit in multiple steps. 16. The method of claim 15, characterized in that the hemo-bag system (200) comprises a closed, sterile bag (218) of substantially transparent, biocompatible material, and wherein the closed circuit is formed in part by the positioning system hemo-bag (200) above the hemo-concentrator (302) when said bag (218) includes an output port (220) at the lower end (204) of the bag (218) and a piping system associated which is connected to the input (306) of the hemo-concentrator (302) for supplying fluid from the bag (218) to hemoconcentrator (302), and an input port (235) at the lower end (202) of the bag (218) and a system associated tube that is fluidly connected to the hemo-concentrator (302) for receiving fluid from the hemo-concentrator (302).
