BLOOD PROCESSING SYSTEMS AND METHODS THAT ASSESS AND RESPOND TO REAL OR POTENTIAL VEIN OCCLUSION CONDITIONS

Systems and methods detect when a potential donor draw occlusion condition occurs. The systems and methods attempt to rectify the condition, e.g., by increasing pressure of the pressure cuff (58) and/or decreasing the commanded draw rate, before generating a processing-halting vein occlusion alarm....

More Information
Summary:Systems and methods detect when a potential donor draw occlusion condition occurs. The systems and methods attempt to rectify the condition, e.g., by increasing pressure of the pressure cuff (58) and/or decreasing the commanded draw rate, before generating a processing-halting vein occlusion alarm. L'invention se rapporte à des systèmes et à des procédés permettant de déceler un éventuel état d'occlusion chez un donneur lors d'une prise de sang. Lesdits systèmes et procédés tentent de remédier audit état, par exemple en augmentant la pression de la manchette à pression et/ou en réduisant le débit de pompage commandé, avant de générer une alerte d'occlusion de veine mettant un terme à l'opération.
