Patent number: 7238320Abstract: A device for oxygenating blood in an extracorporeal circuit includes a first structure suitable to delimit a portion of space-containing capillaries made of microporous membrane. The capillaries convey oxygen and are wet externally by blood flowing through a portion of space between an intake connector, which is connected to a venous line of the extracorporeal circuit, and a delivery connector. The device includes a second structure monolithically connected and contiguous to the first structure. The second structure is suitable to contain blood filtration means that divide the portion of space delimited thereby into a blood distribution chamber, provided with an air vent and connected to the delivery connector of the first structure, and a blood collection chamber provided with a delivery connector connected to the arterial line of the extracorporeal circuit.Type: GrantFiled: March 19, 2004Date of Patent: July 3, 2007Assignee: Sorin Group Italia S.r.l.Inventors: Nicola Ghelli, Edgardo Costa Maianti, Ivo Panzani

Patent number: 7156800Abstract: A method and apparatus for controlling the washing step in a blood centrifugation cell in which washing solution is introduced into the blood centrifugation cell and the cell contains compacted red cells and supernatant at the beginning of the washing step. The apparatus can comprise various sensors and a computer. The sensors sense and transmit to the computer three inputs. The first input is indicative of the total volume of blood that enters the cell during the filling step and the total amount of washing solution that enters the cell during the washing step. The second input is indicative of the hematocrit value of the blood introduced during the filling step. The third input is indicative of the geometric characteristics of the cell. Based on the inputs, the computer executes an algorithm that produces a first output that is the concentration of the supernatant in the supernatant-washing solution mixture.Type: GrantFiled: December 13, 2005Date of Patent: January 2, 2007Assignee: Sorin Group Italia S.r.l.Inventors: Ivo Panzani, Sergio Romagnoli, Massimo Belloni
