Design and development of a tracking system for autoinjectors using Bluetooth low energy with autonomous emergency alert

Résumé

Anaphylaxis has propelled the use of adrenaline autoinjectors (AAI) globally. This is to ensure patients administer themselves whenever they experience an allergic reaction, anywhere, to reduce the severe consequences that would result if medical services far located far. Common issues identified with AAI: They are forgotten, not simple to use, and often misplaced. This paper proposes a connected mobile system with an e-cap for AAI using wireless communication protocol, Bluetooth. The hardware in this paper comprises of an Arduino nano BLE module, LED, and magnetic buzzer. Several algorithms for tracking were used and quadratic line of best-fit, produced better distance approximation. The accuracy of the system was affected by electromagnetic interferences. Further development is required to improve the robustness of the system using other wireless technologies and algorithms.
