Nancy Kerr and Mark Hauswald of Global Health Partnerships in the U.S. are creating circumferential abdominal-pelvic pressure (CAPP) devices to decrease blood flow to the pelvic organs and control postpartum hemorrhage. The devices are inexpensive, constructed using local materials such as bicycle tires, and can be made on-site in the developing world. With a grant from The Gates Foundation’s Grand Challenges Explorations competition, Kerr and Hauswald will evaluate the use and acceptance of their devices in Nepal. The idea of using locally available supplies to create a low-tech but high-impact device is incredibly exciting.
