Abstract
With the accelerating trend of global population aging, the incidence of diabetes among the elderly continues to rise. Insulin injection, as one of the key methods for treating diabetes, has disadvantages like high operation difficulty and poor compliance among elderly patients in actual application. This research conducts in-depth investigations on the characteristics of elderly diabetic patients, identifying key difficulties they experience in using needle-free insulin injection products. On this basis, a design solution covering overall interaction reconfiguration and function optimization is proposed, with needle-free insulin injectors as the core to develop an integrated support system tailored for the elderly. Results demonstrate that this optimized design exhibits significant effectiveness in enhancing the device experience of elderly patients and improving compliance. The innovation of this research lies in approaching the needle-free injection issue from an overall medical-patient perspective, providing a new solution strategy to meet elderly diabetic patients’ device needs, with extensive potential for promotion and application.
