This ongoing project explores a mechanical approach to diaphragm pacing that can support patients with compromised respiratory function. The prototype integrates sensing and actuation to deliver a controlled breathing cadence.
Diaphragm Pacing Device
Mechanical pacing device that stimulates the diaphragm to assist breathing using controlled actuation.
Key Reminders
- Describe how the threading mechanism delivers repeatable diaphragm stimulation.
- Explain the sensor feedback and calibration workflow.
- Share how the team iterated with clinicians on usability.

Clinical Need
The project addresses respiratory assistance by mechanically pacing the diaphragm when autonomous breathing is impaired. The design targets repeatable, comfortable actuation and straightforward clinical setup.
System Architecture
An Arduino coordinates a motor-driven threading mechanism with a force sensor to pace the diaphragm at a controlled cadence.
c code
Code example forthcoming
Motor control loop and pacing cadence logic.
Mechanical Design
The mechanism uses a motor and medical tubing to deliver pacing motion. An endotracheal tube and PICC line adapters enable repeatable placement.
Testing and Validation
The prototype was tuned to achieve a steady pacing rate and reliable force response across test runs.
Demo and Next Steps
Future work includes clinician-in-the-loop evaluation and safety analysis for long-duration use.
