Disposable cartridge-based blood glucose design and development

This cartridge-based meter was developed for Hypoguard after they saw they needed to step aside from the incremental improvement of meter and develop a product that delivered real benefit to the user. The meter held 100 biosensors allowing the user to perform 100 tests before the meter was recycled. It enabled users with poor dexterity to simply rotate a handle to present a bionsensor to perform a test, rather than try to remove a biosensor from a vial and then insert it into a meter.

It was a very technically challenging project. The biosensors had to be protected from moisture, so the meter was moulded in Polypropylene to provide an effective moisture barrier for them. A simple elastomer coated plastic hinged door allowed the sensors to be released and the exit was plugged again. Moulded desiccant within the meter absorbed any residual moisture. Extensive testing was carried out using data loggers and an environmental chamber to enable accelerated testing to be carried out.
The product was manufactured in the UK, with the technical assembly defined fully in ProENGINEER. (Developed whilst employed at Pearson Matthews).
