[[File:Sally3.jpg|thumb]] {{Medical equipment data | health-topic = Maternal mortality | health-classification = Diagnosis }} {{Project data | status = Clinical trial | location = Texas, United States }} == 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. == 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. == 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. == Designed by == * Designed by: Lauren Theis and Lila Kerr, two undergraduate students of Rice University's 360: Institute for Global Health Technologies == References == === Peer-reviewed publication === Brown, J., Theis, L., Kerr, L., Zakhidova, N., O'Connor, K., Uthman, M.
