The Iterative Design Process

A flow chart was utilized to visualize the iterative design process for this project.

 

The itemization below shows a summary of our process.

  • Medical Problem:
    • Pocket hematoma formation at cardiac implantable electronic device (CIED) sites.
  • Proposed Solution:
    • Design of a compression vest at the CIED site
    • Design criteria include:
      • High motility
      • Cost-effectiveness
      • Appropriate pressure 
  • Design Features:
    • Torso straps for mobility and fit.
    • Durable, breathable elastic fabric over the cardiac device site.
    • Integrated PVC airbag for customizable compression controlled by an air pump-button.
  • Design Process:
    • Preliminary 2D sketches showing the shape and fit of the device.
    • Development of a 3D computer-assisted design (CAD).
    • 3D printing of the CAD design for visualization.
  • Prototype Development:
    • Build a prototype using materials outlined in the design criteria.
    • Test effectiveness through clinical trials with a target population of 60+ year old male and female patients.
  • Clinical Trial Evaluation:
    • Assess the need for design changes based on trial outcomes.
    • Review results with patients and clinicians to identify potential sources of error (e.g., mechanical, design-related, manufacturing, ethical).
    • Make revisions and develop a new design if necessary.
    • Retest the revised design in clinical trials.
  • Finalization Process:
    • If no further changes are required, finalize the design.
    • Add customizable options and features for users.
  • Regulatory and Production Steps:
    • Apply for a patent and Class II medical device classification.
    • Obtain necessary certifications and comply with guidelines before mass production and marketing.
  • Post-Market Monitoring:
    • Monitor patient satisfaction.
    • Ensure continued compliance with safety certifications.
