Abstract: A base supports an adjustable seat in the interests of automated weight shifting in order to relieve pressure. An orientation-adjusting system allows for the seat to be shifted to create aforementioned pressure relief. The seat has a sitting platform and a back support. The sitting platform is tiltable thanks to a joined tilting platform of the orientation-adjusting system. The back support can be inclined relative to the seat by means of a reclining mechanism of the orientation-adjusting system. A control module is programmed to direct shifting of the seat. The control module uses data gathered from a sensor system and an orientation feedback system to ensure that any adjustments made via the orientation-adjusting system are only performed when it is safe to so. A communication module and data storage unit further expand upon the capabilities of the system.

Abstract: Provided herein is a composition comprising transfusable red blood cells having improved storage capability, wherein a C9 inhibitor has been administered to the composition and thereby the composition has a reduced amount of red blood cell lysis as compared to a control. It is a surprising finding of the present invention that addition of a C9 inhibitor to a blood sample decreases the amount of red cell lysis in the sample over time. Accordingly, the present invention provides red blood cell compositions that can be stored for greater lengths of time before use, i.e., transfusion, and/or that have a reduced amount of storage lesion.
