Connected Pill Management System
Automated Medication Adherence Platform
Medication adherence is a persistent challenge. There are complex dosing schedules, multiple prescriptions, and inconsistent routines often lead to missed or incorrect doses, impacting patient outcomes.
We partnered with Xena Medical Technologies to develop a connected pill management and dispensing platform designed to simplify medication routines through automation, intuitive interaction, and cloud connectivity. Our work focused on creating a functional proof-of-concept prototype systems that demonstrates the feasibility of a novel dispensing architecture and establishes a foundation for a future production-ready product.
The platform was designed to transform medication management into a simple, guided, and reliable experience.
Key objectives included:
- Automating medication dispensing at the correct time and dosage
- Reducing cognitive load for patients and caregivers
- Providing connectivity to mobile and cloud-based applications
- Supporting user-friendly interaction and clear feedback
- Establishing a scalable architecture for future commercialization
At the core of the system is an innovative cylindrical tumbler-based dispensing mechanism designed to store and deliver medication in a controlled, repeatable manner.
