[edit] Problem being addressed
Anemia is a major cause of maternal mortality and it remains a prominent issue in developing countries. Methods to accurately diagnose this condition are inadequate in these regions. The Sally Centrifuge, with its mechanically-powered, cost-efficient and portable design, hopes to bring accurate diagnostic technology to low-resource areas.
[edit] Detailed description of the solution
The Sally Centrifuge is composed of hair combs, a salad spinner and a round plastic container. It spins small capillary tubes filled with blood for ten minutes with manual pumping. A rudimentary gauge is then used to assess hematocrit values (or the ratio of red blood cells to the total volume) to determine whether a person is anemic. The centrifuge can spin up to 30 samples in ten minutes at a rate of 950 rpm.
[edit] Describe its relevance to resource-constrained settings
The Sally Centrifuge is optimal for use in resource-constrained settings because it does not require electricity. It is inexpensive, lightweight, portable, robust and fairly easy to operate. Moreover, studies have shown that it is considerably accurate and effective.
