The following projects were selected by the design teams:
Device for Separating Serum from Red Blood Cells
Centrifuges are usually used to separate red blood cells from serum.
This is necessary for a variety of tests. Hematocrit tests measure
the percentage of red blood cells in the blood. Immuno-assays produce
a visible reaction which is obstructed by the presence of red blood
cells. A device is needed to separate the red blood cells from the serum; it might
be mechanical, such as a centrifuge or chemical, such as a clotting
agent which does not interfere with subsequent tests. It is
preferable that this device does not require an electric motor, and it
should be very reliable. Existing centrifuges often break down and
remain idle until a repair technician comes to the site, often several
month later.
Collapsible Structure for a Mobile Clinic
In order to effectively treat patients who live far from existing
clinics, a mobile clinic may be used. When in use, there must be
space for examining patients and performing tests. This structure
must be able to be stored and transported easily and be sturdy enough
to withstand being transported on poor roads and be able to stand up
to other environmental stresses.
Computerized Diagnostic Program
In the syndromic method for diagnosing and treating disease, the nurse
follows a flow chart to determine the most likely cause of illness and
the appropriate treatment. The Ministry of Health in Botswana is
considering using computers to facilitate the syndromic method of
diagnosis at the primary hospitals. They are interested in a
Newton-based (or other small hand-held computer) system to analyze
symptoms and store data.
Oxygen Concentrator
Patients with respiratory problems often need air with a higher oxygen
content. A device which can concentrate oxygen is needed.
Water Sterilization Project
Clean water is required for the operation of the clinic-- for washing, dringking and maintaining good hygiene. There may not be a source of clean water near the site, so a system for treating the water is needed.
