Balloons — including modeling balloons and standard latex balloons — simulate thin-walled, elastic, distensible anatomical structures. Inflate, segment, or layer to approximate hollow organs, bowel loops, and fluid-filled cavities where compliance and volume change are key functional characteristics.
Tissues
| Tissue | Visual | Tactile | Simulator | Notes |
|---|---|---|---|---|
| Gallbladder | Laparoscopic Cholecystectomy Simulator | Green balloon; sand or ground coffee simulates gallstones. Per ALL-SAFE shopping list. | ||
| (Structural — lung analogue, not tissue simulant) | — | — | Brannan Chest Tube Simulator | Per Brannan 2021: two punching balloons serve as lung analogues, inflated via a bag valve mask through a plastic-tubing "trachea". Creates residual air pressure within the thorax cavity that trainees must decompress during tube thoracostomy practice. |
Troubleshooting
- Suturing practice — Balloon material tears on needle passage and cannot hold sutures.
- Training with latex-allergic participants — Latex proteins can trigger anaphylaxis.
- Procedures requiring wall thickness — Balloons are too thin (~0.1 mm) to simulate vessel walls requiring needle passage or anastomosis.
- Contact with petroleum lubricants — Petroleum degrades latex within minutes.
Alternatives
| Alternative | Best For | Trade-offs |
|---|---|---|
| Nitrile balloons | Latex-free environments | Less elastic; harder to source |
| Glove fingers | Similar elasticity; readily available | Smaller volume; different shape |
| Condom | Tubular organ simulation | Similar compliance; alternative latex source |
