TissueDB/Simulators/Chest Tube Simulator (Man-O-War)

From Appropedia


The Man-O-War Chest Tube Simulator is a low-cost manikin for training chest tube insertion (tube thoracostomy) and management, built from inexpensive materials that an educator can self-produce.[1] It supports the complete chest tube insertion procedure: rib palpation, syringe puncture and local anaesthesia, skin incision, blunt dissection, pleural puncture, tube placement, and suturing.

Field Details
Features and Basic Operation The chest wall presents a palpable rib cage with individualised intercostal spaces and gives a flesh-like feel when palpating and inserting a drain. Each intercostal space tolerates up to 3 punctures — at least 30 insertion attempts per chest wall — and the chest-wall and pleura layers can be replaced in about 15 minutes. After insertion the model can be opened to confirm exact tube placement.
Current Development Status Pilot-tested with emergency physicians at Tunisian congresses in 2022; the source paper reports no validation, and a satisfaction survey is forthcoming.
Estimated Build Time and Cost US$15
Specialized Tools and Equipment Straight grinder — used to cut the plastic bucket between the ribs to individualise the intercostal spaces.

Tissues

Tissue Qty Material Cost Notes
Bone (ribs) 10 (5 pairs) Plaster Bandage $2.50 Stiffened plaster over the bucket "ribs"; the source states they "offer a real sensation of bones on palpation".
Chest-wall soft tissue (parietal wall) 1 Foam mattress ("extra dur", extra-firm) $2.50 Represents the authors' "parietal wall"; the source reports a "similar density to flesh" and "a real feeling when palpating and introducing a drain". ⚑ Open for review: the source names only a "foam mattress ('extra dur', extra-firm)", not the polymer — the "Polyurethane Foam" class link is provisional pending Felipe's canonical foam class.
Pleura (parietal) 1 Gaffer Tape Gaffer tape molded over the intercostal spaces (atop the cellophane wrap); the source states this assembly "mimics the parietal pleura". Not separately itemised in the source's Table 1; the stated total includes it.


Structural Parts

Part Name Qty Material Cost Notes
Thorax frame 1 Funnel-shaped plastic bucket $3.00 The "ribs" are drawn on and cut from the bucket walls; the bucket provides the thoracic form and rib-cage skeleton.
Cellophane wrap 1 Cellophane paper (Plastic Film) $1.50 Rolled around the bucket before the gaffer-tape layer; the base on which the pleura assembly is built.
Support base 1 Basin with 5 kg white cement $3.50 The bucket is fixed into the cement-filled basin for stability during procedures. The source's Table 1 prices the basin, cement and screws together.
Fasteners Not specified in source Screws and nuts (incl.) Secure the foam mattress to the bucket frame; priced with the basin line in the source's Table 1.


Build Instructions

Phase 1: Frame Construction

  1. Acquire frame. Buy a funnel-shaped plastic bucket with upper diameter 20 cm, lower diameter 35 cm, and length 30 cm.
  2. Mark rib layout. Draw a rib cage on the bucket with a permanent marker. Place the sternum line in the middle and mark 5 pairs of ribs laterally on both sides. Make the ribs 2 cm wide and 10–15 cm long, leaving the intercostal spaces 2 cm wide.
  3. Cut intercostal spaces. Cut the plastic between the ribs with a straight grinder to individualise each intercostal space.

Verify: Each rib is individually defined with open, accessible intercostal spaces between them.

Phase 2: Tissue Layers

  1. Apply bone simulation. Cut a plaster casting roll into 4 cm strips lengthwise. Wrap the strips around each rib, flatten with the fingers, and overlap each pass. Allow the plaster to dry. The ribs become stiff at approximately 1 cm width.

Verify: Dried ribs are rigid and palpation produces a firm, bone-like sensation.

  1. Apply pleura substrate. Roll cellophane paper around the bucket.
  2. Apply pleura simulation. Place gaffer tape along the intercostal spaces and mold it firmly over the spaces.

Verify: Gaffer tape covers all intercostal spaces; the cellophane-tape assembly gives consistent puncture resistance across all spaces.

  1. Attach chest wall. Anchor a 60 × 30 × 5 cm "extra dur" (extra-firm) foam mattress to the bucket with screws and nuts, so the chest wall can be unscrewed and replaced once its intercostal spaces have too many cuts to reuse.

Verify: The foam is secure, and the rib positions and intercostal spaces are palpable through it.

Phase 3: Base Assembly

  1. Create support base. Fill a basin with 5 kg of melted white cement, fix the bucket into the cement, and allow it to set completely before use.

Verify: The simulator stands upright without external support and the base stays stable during chest-tube insertion force.
