A Study of the Electromedics Autotransfusion System, CRADA PC93-010, Final Report

PDF Version Also Available for Download.

Description

This report describes the work at PETC to evaluate flow dynamics in the Electromedics autotransfusion system. First, a literature survey was conducted for flow studies in centrifuge systems. Although no flow studies were identified for Latham-type bowls, pertinent literature for general centrifugal separation was found and reviewed. Sample measurements were taken with a Laser Doppler Velocimetry (LDV). The data indicates that LDV is a useful tool in flow analysis. Velocity, turbulence intensity, and bowl vibration are all accurately measured with LDV. For optical imaging of particle separation it is necessary to use fluorescent doped particles and color separation. This allows ... continued below

This report describes the work at PETC to evaluate flow dynamics in the Electromedics autotransfusion system. First, a literature survey was conducted for flow studies in centrifuge systems.

Sample measurements were taken with a Laser Doppler Velocimetry (LDV). The data indicates that LDV is a useful tool in flow analysis. Velocity, turbulence intensity, and bowl vibration are all accurately measured with LDV. For optical imaging of particle separation it is necessary to use fluorescent doped particles and color separation. This allows each type of particle to be observed in a mixture. A market survey was completed and sources for fluorescent dyed particles of three different emission wavelengths and corresponding optical bandpass filters were identified.
