Abstract[edit]

  • The Stethoscope is one of the most basic medical tools. It allows a trained medical professional to diagnose issues with the heart and lungs. Stethoscopes come in a range of prices and quality, but all are breakable. This Stethoscope only requires some surgical tubing or similar airtight tubing and 3D printed parts.

Bill of Materials[edit]

Tools needed for fabrication of the OSAT[edit]

  1. MOST Delta RepRap or similar RepRap 3-D printer
  2. Knife or scissors

Skills and Knowledge Necessary to Make the OSAT[edit]

  • No special skills needed to build, To use this device propertly takes some training.

Technical Specifications and Assembly Instructions[edit]

  1. There are 7 seperate prints for this device listed below with there print times (depending on your printer and settings)
    1. Bell
      1. Approximately 2 hours
    2. Y tubing joing
      1. Approximately 1/2 hour
    3. 2 small tubes
      1. Approximately 1 hour each
    4. Cross piece
      1. Approximately 3 hours
    5. 2 earpieces
      1. Approximately 4 hours each
  2. Assembly time depends on how much post-printing corrections you need to do. Some filing or sanding may be necessary for a great fit.
    1. Printed Parts
    2. Cut the tubing to desired length,
      1. About a 1.5 feet from the bell to the Y joint
      2. 2 at about 4 inches from the Y joint to the small straws
      3. 2 small tapered pieces to act as ear buds on the end of the long earpieces
    3. Simply fit the pieces together, I did not use any glue but that is an option.

Common Problems and Solutions[edit]

  • For a really tight plastic on plastic fit, some sanding or filing will need to be done.

Cost savings[edit]

  • Costs
    • Plastic at $25 per kilogram, 45 grams, $1.13
    • Rubber tubing $2.30 per foot, 2 feet, $4.60
  • Commercial Equivelent
