General Information

3D-printed pink ribcage mounted in a pink, black, and white support frame, from Bettega 2019.
3D-printed rib framework of the Bettega chest tube simulator (Figure 1, Bettega AL et al. 2019, CC BY 4.0).

The Bettega Chest Tube Simulator is a low-cost 3D-printed thoracic model for training closed chest drainage (tube thoracostomy) in medical students. The simulator combines a 3D-printed rib framework derived from a chest computed tomography scan with internal pleural and cavity layers assembled from unspecified materials, and supports the full four-step drainage procedure: 1.5 cm skin incision, blunt dissection of planes into the pleural cavity, finger sweep through the pleural orifice, and drain insertion to the mark.[1]

Field Details
General Information A low-cost 3D-printed chest tube trainer for closed chest drainage, positioned by the authors as an alternative to porcine animal models. TissueDB comparator chest-tube simulators include Man-O-War (Nasri) and Carter.[1]
Features and Basic Operation Not stated in source
Current Development Status Validated in a randomised controlled trial against a porcine animal model with medical students.[1]
Estimated Build Time and Cost ~US$133[1]
Specialized Tools and Equipment Not stated in source
Version Not stated in source
Development Team Contact Information Developed at the Federal University of Paraná (UFPR) Faculty of Medicine and the Federal Technological University of Paraná (UTFPR) Academic Department of Mechanics, Brazil.[1]

Tissues

Tissue Qty Material Cost Notes
Bone (ribs) 1 framework Material not specified in source — 3D-printed bony framework derived from a chest computed tomography scan. The source does not name the printing filament.[1]
Skin and Subcutaneous Tissue 1 outer overlay Material unspecified in source — Yellow outer overlay visible in Figure 2 of Bettega 2019. Source describes only "various materials" and does not name this layer.[1]
Pleura 1 internal cavity lining Material unspecified in source — Internal pink and purple structures shown in Figure 2 form the pleural and cavity simulation. Source states only "various materials that contributed to form the simulation of the thoracic cavity and pleura".[1]

Thoracic support frame 1 Material unspecified in source — Pink, black, and white display frame visible in Figure 1 of Bettega 2019. Frame is not described in the source paper.[1]


Build Instructions

Phase 1: 3D-print the rib framework

  1. Obtain a human chest computed tomography scan and perform anatomical analysis of the tomography plus faithful 3D surface editing to prepare the print model.[1]
  2. 3D-print the bony framework of the thorax from the prepared model, through partnership with Federal Technological University of Paraná (UTFPR), without dedicated funding.[1]

Source does not report slicing software, infill percentage, layer height, print orientation, support strategy, nozzle temperature, filament make, or print time. Total simulator cost, inclusive of 3D printing and all subsequent assembly, is approximately US$133.[1]

Phase 2: Assemble the thoracic cavity and pleura

  1. Test candidate materials for the thoracic-cavity, pleural, and skin-overlay layers, and integrate them around the 3D-printed ribcage to simulate the thoracic cavity and pleura.[1]

Source states only: "After printing the ribs, tests were performed with various materials that contributed to form the simulation of the thoracic cavity and pleura." The paper does not provide a step-by-step assembly procedure or name the specific materials used. Figure 2 of the source paper demonstrates the completed simulator with a yellow outer overlay, the 3D-printed ribcage, and internal inflatable structures representing the pleural space.[1]
