Patent number: 7211312Abstract: The zone of weakening, which is designed as a slot (6a), is bordered by film material (7) on both sides according to length, i.e., across the direction of loading, which is indicated by the arrows F. Tearing (8) which progresses from the edge because of microscopic damage comes to a standstill at the slot (6a) at the latest, because stress peaks are dissipated here and the locally increased stresses are diverted into elements of the film material (7) which are under less stress. Other embodiments include a locally interrupted adhesive layer for separation of an upper film layer from a lower film layer, these two film layers being otherwise glued together. The adhesive-free recesses here constitute zones of weakening in the sense of the present invention. This therefore prevents tears from spreading from one film layer to the next. Furthermore, the propagation of tearing is counteracted due to the dissipation of stresses when a tear that forms in the film layer reaches the zone of weakening.Type: GrantFiled: February 20, 2004Date of Patent: May 1, 2007Assignee: Schreiner Group GmbH & Co. KGInventor: Ulrich Moosheimer

Patent number: 7048709Abstract: The disclosure includes a flexible bag (1) intended to receive a biological fluid with a view to its centrifugation. The bag includes an external enclosure (2) formed by two sheets of flexible plastic (3, 3?) connected at their periphery (4) so as to define an internal volume (5) for the fluid. The external enclosure (2) is provided with at least one inlet (6) and/or outlet (7) orifice for the fluid. The bag (1) also includes means (8) for the temporary association of at least one component with the bag (1). The means (8) is disposed on the external enclosure (2), in which the temporary association means are assembled on the bag (1) on a part of the periphery (4) of the enclosure (2) and are arranged to allow the insertion of the component between the means (8) and the enclosure (2) so as to provide temporary association during the centrifugation of the bag (1).Type: GrantFiled: June 12, 2002Date of Patent: May 23, 2006Assignee: MacoPharmaInventors: Francis Goudaliez, Thierry Verpoort, Gus Ribeiro

Patent number: 7044940Abstract: A storage container (1) for a suspension used for medical purposes, in particular for ultrasonically assisted treatment of periodontitis, dental cleaning or dental preparation, comprises a flexible pouch (2), the interior of which is accessible via a charging and discharging nozzle (5). Situated in the interior of the pouch (2) is a distance element (6), in which a groove system (8, 9, 10) is incorporated. The groove system communicates with the interior of the charging and discharging nozzle (5). When the pouch (2) of said storage container (1) is pressed flat during removal of the suspension it contains, the opposing sides (3, 4) of the pouch (3) are applied during the final phase of emptying against the distance element (6). The groove system (8, 9, 10) contained in the latter however remains clear and forms a path, via which even the last residues of the suspension may be reliably removed from the pouch (2).Type: GrantFiled: April 11, 2000Date of Patent: May 16, 2006Assignee: Dürr Dental GmbH & Co. KGInventors: Rainer Hahn, Uwe Grotz, Ulrich Prager

Patent number: RE39449Abstract: A system dynamically adjusts the delivery rate of a cryopreservation solution to red blood cells to permit freezing. The delivery rate is preferably determined according to an equation that maintains a linear change of red blood cell osmolarity over time so as to prevent osmolarity shock of the red blood cells. In the preferred embodiment, the system includes a controller that is preconfigured to automatically deliver the cryopreservation solution to the red blood cells in accordance with the equation. The system may also support the recovery of thawed red blood cells by diluting the red blood cells and washing them of the cryopreservative. Again, the system preferably adjusts the delivery rate of a dilution solution so as to prevent osmolarity shock of the red blood cells during the recovery phase. The recovered red blood cells may be suspended in a preservation solution to further increase their shelf-life following the recovery phase.Type: GrantFiled: August 27, 2004Date of Patent: December 26, 2006Assignee: Haemonetics CorporationInventor: Etienne Pages
