Chest Tube Trainer (Rib Model) | Thoracostomy

DIY chest tube trainer designed for practicing thoracostomy and tube thoracostomy placement using a 3D-printed rib structure with a silicone skin overlay.

This model can be used as a standalone trainer or placed over an existing simulator (e.g., Laerdal SimMan 3G) to create a low-cost, repeatable training solution.

The rib model is adapted from an open-source design originally published on Thingiverse model 4018084, which provides a set of ribs specifically intended for chest tube simulation training.

🔥 Why This Trainer Works

• Realistic rib landmarks for proper placement
• Silicone skin layer allows incision and blunt dissection practice
• Reusable and low-cost compared to commercial trainers
• Can scale easily for group training

🎯 Ideal For

• Emergency medicine training
• Surgery and procedural skills labs
• EMS / paramedic education
• Simulation centers and GME programs

🧠 Key Features

• 3D-printed rib cage structure
• Silicone overlay simulates skin and soft tissue
• Compatible as an overlay on full-body simulators
• Supports repeated practice of:
  • Landmark identification
  • Incision
  • Blunt dissection
  • Tube placement

🧰 Materials Needed

• Printed rib model
• Platinum-cure silicone (e.g., Ecoflex series)
• Silicone pigments 
• Flocking (Optional)
• Mold or casting method for skin layer (baking sheet works perfectly)

🖨️ Printing Notes

• PLA or PETG recommended
• Increase wall count for durability
• Ensure rib surfaces are smooth for realistic feedback

✅ Expected Result

The finished trainer provides realistic rib spacing and tactile feedback for practicing chest tube insertion, including identification of intercostal spaces and controlled dissection.
