💭 Problem Definition

CLIENT BACKGROUND

<aside> 📌

Sayid Jarrah is an ostomate living with rheumatoid arthritis, which causes him significant joint pain. Additionally, he has sensitive and uneven peristomal skin, which greatly increases both the difficulty and the time required when it comes to changing his ostomy appliance before the next gastrointestinal output.

</aside>

NEED STATEMENT

Design a custom device for Sayid Jarrah that increases the efficiency of ostomy appliance changes by reducing the overall time taken and pain induced in doing so.

TRANSFERABLE AND TECHNICAL SKILLS

✔️ 3D Printing (PrusaSlicer)

✔️ Computer Aided Design (Autodesk Inventor)

✔️ Professional Documentation and Academic Writing

✔️ Teamwork and Collaboration

✔️ Effective Communication

Figure 1: Our client currently uses a two-piece ostomy appliance which consists of a separate skin barrier, an ostomy bag, a closure clip, and a ceramide ring accessory designed to minimize skin irritation [2].

CONSTRAINTS & OBJECTIVES

The ostomy appliance must:

  1. Create an even skin barrier around the stoma.
  2. Be able to contain gastrointestinal output.
  3. Be a two piece appliance.
  4. Not cause pain during application for a patient with rheumatoid arthritis.
  5. Account for varying stoma diameter and height.

The ostomy appliance should:

  1. Be easy to apply.
  2. Allow for efficient and quick ostomy bag changing.
  3. Be comfortable for individuals with sensitive skin.
  4. Be durable.
