Oxford Biosensors had an electro-chemical sensing technology to be used with whole blood. Maddison was asked to develop a point of care solution from concept through to production specification.
Challenges and Development
To make the system cost-effective, we had to design a solution in which the electrodes were disposable. The handheld unit had to contain the sensing platform in a compact, portable design. Maddison created a solution with a low-cost disposable cartridge for the blood sample which slotted into the hand-held unit without risk of cross-contamination. The results were displayed on the screen within seconds and, by incorporating an off-the-shelf printer based in the docking station, we were also able to provide a written result. A re-chargeable, battery powered hand-held reader was designed, prototyped and tested, followed by the creation of a manufacturing specification.
