A major drug developer came to Paramit looking for a simplified drug delivery method for their new treatment for macular retinopathy. The device was to undergo FDA approval so many precautions needed to be taken.

ID was tasked with working with engineering to develop a mechanism that could deliver the drug into the eye with one hand. We created dozens of models to test the best form for the hand and positioning for the index finger for the drug delivery button.

The blue grip provided friction where it’s needed most, but the grip was removed on the bottom to allow easy rotational positioning with one hand. The clear window had to be visible in order to show the drug in position before the final press of the button.

The best forms for testing were determined first with mockups shown below and were then user tested with a panel of doctors.

Working with Paramit Engineering, we converted the proven usage workflow into mechanicals that maintained design intent while being manufacturable at high volumes.

We developed the testing script, procedure and scoring methods using standard testing practices. We then ran the test, tabulated the results and shared the results with the customer.

This project is still undergoing review. The mechanical design and resultant form resulted in at least one patent for the team and myself, with potentially more to follow.
