Intestinal infections like worms are common in many poor
countries and even when continuous
treatment is arranged at low cost, diagnostics and identification of
treatment fails due to unavailability of diagnostic equipment and resources.
With the proliferation of raspberry pi micro controller, data transfer networks
and digital microscopy applications the stage is set for alternatives to
conventional microscopy in endemic areas. Our aim was to show, as proof of
concept, that it is possible to achieve point-of-care diagnostics by an
inexpensive mini-microscope for direct visualization on a display and remote
diagnostics by computer vision embedded in a 3D printed casing. As regards the design concept, there was co creation
between health workers and lab technicians to identify their needs. These
insights are interpreted and translated to an envisioned design concept, that
is presented at the end of this report, The results show that parasitic schistosomiasis worm eggs can be
recognized by imaging using two webcams
stripped off the optics in reverse order. Images of eggs from the blood
fluke S. haematobium present in urine of an infected patient
could be interpreted visually and by computer vision. The method offers both an
inexpensive alternative to conventional microscopy and diagnostic assistance by
computer vision. This enhances both sustainability and affordability. The
images captured by the device are processed by the algorithm embedded in the
raspberry pi which helps healthcare staff to provide a reliable diagnosis,
either in person or remotely.e
