Research Topics


The purpose of this Phase II project is to provide advanced development of a lightweight, rugged battery operable multipurpose medical centrifuge for combat casualty care units based on innovative concepts tested in the Phase I study. The centrifuge will be equipped to perform microhematocrit, urine sediment, fecal concentration, plasma preparation, quantitative buffy coat analysis tube centrifugation and manual settings using a built-in two stage rotor system and standard tubes. The split rotor designdecouples the high speed portion of the rotor for the hematocrit and QBC separations to conserve battery power and reduce weight and strength required for the larger buckets which are only driven when filled. The prototype integrates a digital semi-automatic hematocrit measuring scale, operators manual and precise experimental protocols for various centrifugation tests by storing then in digital memory. The HELP files are retrieved by simple graphical three key user input and displayed on an integral LCD screen. The prototype apparatus developed under Phase I demonstratesthe feasibility of a multipurpose centrifuge meeting all the requirments set for5th by the original objectives and provides a substantial basis for an orderly Phase II advanced development. The Phase II effort will provide for advanced engineering design for manufacture and qualify the system for the ruggedized medical environemnt. Five pre-production devices will be delivered for evaluation.
