Trajan Scientific and Medical approached us with an existing product that needed improvement. They had designed a microsampling device for healthcare professionals but wanted to expand their customer base to patients and caregivers too. We needed to understand the key steps for successful sampling and create a failproof design solution for someone taking a blood sample for the first time at-home.

Depending on a person’s experience—or lack thereof—people have different techniques for collecting a blood sample. It was important that the product design addressed these differences, but it was also important that the instructions were easy to understand too.

Based on our analysis and feedback from potential customers, the new hemaPEN allows a user to draw a sample from any angle and visually confirm when the sample is complete. These features create an easy-to-use device and give users the confidence they took a successful sample. We also designed and tested the Instructions for Use using large illustrations and an instructional video that focuses on the key use steps.
