Redefining Oral Drug Delivery: From Human-Dependent Administration to Semi-Automatic Dosing for Prevention of Leakage and Dosing Errors

• Mechanical Dose-Setting System: Replacement of visual volumetric assessment with a defined mechanical constraint mechanism to ensure consistent delivered volume independent of human interpretation.

• Volumetric Scale Durability: Integration of an internal 3D scale to mitigate the risk of graduation fading and long-term degradation associated with surface-printed markings.

• Fluid Leakage Mitigation: Implementation of optimized adapter and tip geometry to prevent fluid loss during container connection, filling, and administration phases.

• Dosing Repeatability: Elimination of recurrent scale verification via fixed volumetric calibration, enabling faster, safe, repeatable dosing and autonomous user administration.
