Through usability research, we found that overall, this insulin injection pen is easy to use. However, there are still some users who encounter usage errors or difficulties in certain stages of use, such as:
Users forget to tap the pen core or air injection during pre injection to prevent internal bubbles. They typed in the wrong place or didn't keep the pen holder vertical, or got the order of tapping and air injection wrong;
Sometimes the indicator lights and pointers are not clear, so users may mistakenly adjust the preset injection dose, especially for patients with visual impairments;
During injection, some users find it difficult to press the dose button with their thumb due to the pen being too long.
Based on these findings, we discussed with the client and listed the improvement directions for the product:
Important Information Reminder:Annotate warnings or reminders about air injection and pre injection on the pharmacy;
Protective measures:Suggest adding a magnifying glass on the dose indicator window and making the odd pointer and even pointer lengths different;
Inherent safety design:Use anti slip finger grooves to maintain good friction when pressing the dosage button firmly.
