摘要

术中经开心口吸血再输可引起脂质微栓子形成并发症,可导致神经认知能力下降或残疾。目前正在开发一种系统,该系统使用声阻抗法从血流中分离脂质和红细胞(rbc),从而减少微栓子,允许将流出的血液重新输入。在这项工作中,一种在线检测技术正在开发,以量化新型声波血脂分离系统的性能。检测技术将使用分光光度法来确定被困在腔室中的红细胞和脂质的浓度,从而提供分离效率的测量。

In-Line Detection Technology for Acoustophoretic Blood/Lipid Separation
Retransfusion of shed blood via cardiotomy suction during surgery causes complications due to the formation of lipid microemboli, which can lead to neurocognitive decline or disability. A system is being developed that uses acoustophoresis to separate lipids and red blood cells (RBCs) from a blood flow, thus allowing retransfusion of shed blood with reduced microemboli. In this work, an in-line detection technology is being developed to quantify the performance of the novel acoustophoretic blood/lipid separation system. The detection technology will use spectrophotometry to determine the concentration of RBCs and lipids trapped in the chamber, thus providing a measure of separation efficiency.
