Empowering Midwives in Uganda: Portable Ultrasound Machine Development

In Uganda, where maternal mortality rates are high, midwives face challenges such as placenta previa, breech presentation, and multiple fetuses. We are collaborating with Dr. Rob Nathan to create a portable ultrasound machine tailored for midwives. The device includes a Lenovo Ideapad s10-3t with a touch screen and an Interson AB 3.5 MHz ultrasound probe. Our software utilizes a DLL written in C++ to interface with the probe, enhancing features based on ultrasound technician Nicole Goldsmith's input. Usability testing plans include evaluations by a local technician and experienced midwives from resource-constrained settings. Future work involves user testing in Uganda, developing platform-independent software, and enhancing the patient data system. Acknowledgments to Dr. Rob Nathan, Dr. David Zar, Ruth Anderson, Beth Kolko, Waylon Brunette, and Nicole Goldsmith.

Presentation Transcript

  1. midwife's ultrasound wayne gerard alexis hope pratik prasad sanjana prasain mitch ishimitsu john porter alex pham matthew hicks

  2. background • uganda: high maternal mortality rate • main complications: placenta previa, breech presentation, & multiple fetuses • ultrasound imaging can detect these complications • we are developing (with Dr. Rob Nathan) a portable ultrasound machine specifically for midwives, who are central to ugandan communities

  3. research & design process

  4. hardware • lenovo ideapad s10-3t • touch screen • interson AB 3.5 MHz ultrasound probe • donated • SDK provided by interson • very minimal, however • DLL written in C++ which encapsulates functions necessary to interface with probe

  5. user interface • originally written in LabVIEW • couldn't interface with DLLs  • switched to C# 2 weeks ago • no problems encountered • features and workflow refined after meeting with Nicole Goldsmith, ultrasound technician • ready for usability testing!

  6. prototype demo

  7. evaluation plans • short term: • 2nd evaluation of features & workflow by UW ultrasound technician Nicole Goldsmith • usability evaluation by 2 local midwives: • both have experience working in international, resource-constrained environments (Vanuatu & Haiti) • long term:  • usability evaluation in Uganda

  8. challenges • hardware interface • unfamiliarity with tools involved • C • sdk itself • Windows API • labVIEW • couldn't interface with our libraries properly • C# works great!

  9. future work • user testing in uganda • platform-independent software • patient data system • more comprehensive help system
