Research And Innovation Of Auto Injectors To Enhance Patient Compliance

The enhanced features and convenience provided by auto injectors has increased patient acceptance towards such self—injection devices in recent years. With a wide range of auto injectors already on the market and more entering soon, patients are now more familiar with this type of technology and expect devices to offer key fundamental features such as dose accuracy, ease—of—use, safety, and related feedback systems.

While designing such devices with the end-user in mind has always been part of most auto injector developments, the traditional emphasis on this relatively new medical device was more focused on features and related specifications. These features would be the incorporation and realization of the pharmaceutical companies’ original injection specifications into the device’s mechanical mechanisms and exterior design. For example, injection time would be dependent on the spring force or adjustments made to the power pack built into the device, whereas feedback forms can be the result of intricate component interactions before, during or after an injection. Other details including information on the primary container, injection depth, viscosity range, and more, were some of the key inputs behind the design of the auto injectors at the time. Today, these features have become mandatory benchmarks upon which new designs are realized, but now with an added emphasis on usability and human factors engineering (HFE) to help enhance the patient experience and to support compliance.
