Mobile Phone Autoinjector

EMERGENCY MEDICATION WHEN YOU NEED IT

Mobile Phone Autoinjector

Archimedic collaborated with Thomas Jefferson University (TJU) in the development of a compact autoinjector integrated into a cellphone case. This drug delivery platform is intended for medical emergencies, such as allergic reactions and overdoses.

CONFIGURATION DEVELOPMENT

Safety Focused Use Cases

The project started by exploring various use cases to activate the autoinjector while mitigating any usability risks. Several concepts were explored at a sketch-level before landing on the primary direction.

SEQUENCING DEVICE ACTUATIONS

Mechanism Development

Next, a mechanical layout was constructed to define the required actuations from injection through medication dispensing, and needle retraction. These mechanisms were constructed through dynamic computer-aided design (CAD) models and analyzed through simulated motion studies.

ISOLATING FEATURES AND SUBSYSTEMS

Subsystem Prototyping

To evaluate key features and functionalities, we isolated critical subsystems (such as latching details) and built iterative rapid prototypes until the functionality was reliably achieved.

FUNCTIONAL TESTING

Prototyping & Testing

Various prototypes were developed to achieve the desired performance. Iterations focused on miniaturization of the mechanisms and achieving critical injection force and speed design inputs. High speed cameras, thermal monitoring, and ballistic gels were used in the testing process.

INSPIRED BY PERSONAL EXPERIENCE

Empowering a Clinical Visionary

This brief video shares Dr. Edmund Pribitkin's vision for the Epicase and how we worked together in making it a reality. Note, this video illustrates an early prototype of the Epicase device, developed by Smithwise, which later became Archimedic through a merger.
