Abstract

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

BOM
- 3D printer
  - Filament
  - STL and/or OpenScad files
- Surgical tubing

Tools needed for fabrication of the OSAT

MOST Delta RepRap or similar RepRap 3-D printer
Knife or scissors

Skills and Knowledge Necessary to Make the OSAT

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

Technical Specifications and Assembly Instructions

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
Assembly time depends on how much post-printing corrections you need to do. Some filing or sanding may be necessary for a great fit.
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

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

Cost savings

Costs
- Plastic at $25 per kilogram, 45 grams, $1.13
- Rubber tubing $2.30 per foot, 2 feet, $4.60
Commercial Equivelent
- Low cost - $7.99 - pedometerusa
- High cost - $75 - Littmann

Savings between $2.26 and $69.27
