Description

Handheld drug delivery devices require a simple and clear design from both the perspective of patient or medical staff operation and the perspective of device manufacturing. In particular, it is advantageous if the external form, or the individual components forming the external form, already possess features that intuitively indicate the device's structure and function to the user. Unfortunately, the handling of conventional drug delivery devices remains too complex, especially under time constraints, whether during manufacturing or particularly during emergency drug administration processes.
