A disposable medical diagnostics device was required to be used in developing countries for sexually transmitted diseases. This rapid test for Chlamydia was to be low cost, simple to use and avoid the possibility for it to be used for other purposes after use to avoid spreading infections.
Maddison were part of a international team of chemists, engineers and materials scientists, led by Dr Helen Lee from the University of Cambridge. The fluidic engineering challenge was to only capture the first 5ml of the male urine stream for analysis to diagnose for Chlamydia. Maddison designed a solution, using carefully designed baffles, channels and air pockets to capture the first 5ml in a removable container whilst allowing the rest of the urine stream to pass by so the male could finish emptying his bladder comfortably.
The usability aspects were considered to make sure it was very intuitive to hold, use and remove the sample container. It also had to be very low cost and designed so that it could not be reused for any purpose.
