20140017718 | ERYTHROCYTE MECHANICAL FRAGILITY TEST - A test for erythrocyte membrane mechanical fragility, involving subjection of a sample comprising red blood cells to a mechanical stress capable of causing hemolysis, and measurement of the hemolysis present after particular extent(s) of the stress. Measurement of hemolysis can be without component separation, such as by cell-counting (optical or non-optical) or by spectral differentiation between cell-free and intracellular hemoglobin. Such tests can incorporate a disposable single-use component that contains an RBC sample during testing, and for certain embodiments the mechanical stress involved comprises (higher-energy) ultrasonic stress. | 01-16-2014 |
20130144247 | BIOLOGIC STORAGE BAG MODIFICATIONS FACILITATING SAMPLE EXTRACTION AND UNIT SUBDIVISION - A storage bag for containing biologic content having a first chamber operable to contain the biologic content, a second chamber separate from the first chamber, and a first fluidic seal system disposed between the first chamber and the second chamber. The first fluidic seal system is positionable between a first position retaining the biologic content in the first chamber and preventing the biologic content from entering the second chamber and a second position permitting at least a portion of the biologic content to flow from the first chamber to the second chamber. | 06-06-2013 |
20130130298 | BLOOD PRODUCT MANAGEMENT METHOD USING RBC DEFORMABILITY-BASED METRICS - A method for using red blood cell deformability testing to improve management of blood product comprising RBC, the method comprising: generating deformability data for red blood cells corresponding to a respective unit of blood product; correlating the deformability data with red blood cell viability or efficacy based on any available direct or indirect in vivo performance data; obtaining a representation of quality for the respective unit of blood product; and based on the representation of quality assigning a relative rank to and/or timing a transfer of the respective unit in an inventory of stored blood product units. | 05-23-2013 |
20130098163 | ERYTHROCYTE MECHANICAL FRAGILITY TESTER USING DISPOSABLE CARTRIDGES - A device for testing erythrocyte membrane mechanical fragility that incorporates single-use disposable containers for holding cell samples, the device comprising: a stressor for subjecting a sample comprising red blood cells to a mechanical stress capable of causing hemolysis, wherein said sample remains within a disposable component during the subjecting; and a detector for direct or indirect measurement of said hemolysis present in said sample after particular extent(s) of said stress, whereby said measurement can occur while said sample remains within said component. In addition, the present disclosure specifically addresses such systems wherein said mechanical stress is ultrasonic stress. | 04-25-2013 |
