Rubber is an elastic polymer material—either natural (latex from Hevea brasiliensis) or synthetic—used in medical simulation for creating flexible, resilient tissue analogues. Its high elasticity, durability, and ability to return to original shape after deformation make it well-suited for simulating elastic tissues, vessel walls, and organ surfaces requiring repeated manipulation.
Tissues
| Tissue | Visual | Tactile | Simulator | Notes |
|---|---|---|---|---|
| Blood Vessel Wall | Yes | Yes | Vascular anastomosis training | Use 3–8 mm diameter tubing. Provides elastic vessel walls for anastomosis practice; accepts sutures; simulates vessel compliance. |
| Skin (elastic) | Partial | Yes | Wound closure with tension | Use 1–2 mm thickness sheet. Elastic recoil simulates skin tension; suitable for suturing with realistic tension dynamics. |
| Bowel Wall | Partial | Yes | Bowel handling and manipulation practice | Use thin rubber tubing. Elastic, collapsible tubes simulate bowel handling; use with lubricant for realistic tactile feedback. |
| Skin | White UW Cricothyrotomy Simulator | Bicycle inner tube segment forming cuttable cutaneous layer over the ABS cartilage skeleton; inner-tube size, grade, and tensioning method not specified in accessible source. | ||
| Skin | D'Auria Cricothyrotomy Simulator | CPS sensor-concealing layer: bicycle-inner-tube skin conceals embedded conductive-foil sensor zones (A–F) on the hardware sourced from the White UW Cricothyrotomy Simulator. D'Auria contribution is the Activity Detection Engine sensor overlay, not the inner-tube skin itself. |
Troubleshooting
- Latex-allergic participants — Natural rubber (latex) proteins can trigger anaphylaxis (1–6% population affected). Screen all participants; substitute with nitrile or silicone.
- Incision training — Rubber does not cut like tissue; provides unrealistic resistance. Use silicone or gelatin for cutting practice.
- Suture-holding applications — Some rubber formulations tear around suture holes under tension. Test suture retention before training session.
- Long-term storage models — Natural rubber degrades with UV exposure and ozone; becomes brittle. Use silicone for permanent models.
Alternatives
| Alternative | Best For | Trade-offs |
|---|---|---|
| Silicone | Non-allergenic; durable; consistent properties | Higher cost; less elastic than natural rubber |
| Latex (balloon/glove) | Very thin elastic membranes; readily available | Allergy concerns; single-use typically |
| Nitrile | Latex-free alternative; good elasticity | Different tactile properties; limited forms |
Used In Simulators
| Simulator | Purpose | Notes |
|---|---|---|
| White UW Cricothyrotomy Simulator | Bicycle inner tube segment forming cuttable cutaneous layer over the ABS cartilage skeleton; inner-tube size, grade, and tensioning method not specified in accessible source. | |
| D'Auria Cricothyrotomy Simulator | CPS sensor-concealing layer on White UW hardware: bicycle-inner-tube skin conceals embedded conductive-foil sensor zones (A–F), forcing the trainee to palpate landmarks before incising. D'Auria contribution is the Activity Detection Engine sensor overlay, not the inner-tube skin itself. |

Overview
[edit source]Rubber encompasses both natural latex rubber (from rubber trees) and synthetic rubbers (neoprene, nitrile, EPDM, silicone rubber, butyl rubber). In simulation, rubber's elasticity, resilience, and durability make it valuable for creating tissues that must stretch, compress, and return to shape repeatedly.

Synthetic rubber types: Synthetic rubber, Neoprene, Nitrile rubber, NBR, Butyl rubber, EPDM, EPDM rubber, Ethylene propylene rubber, SBR, Styrene-butadiene rubber, Polyisoprene
Form variations: Rubber sheet, Rubber tubing, Rubber band, Rubber strip, Rubber membrane, Rubber cord, Rubber gasket
Medical/simulation terms: Elastomer, Elastic polymer, Rubber compound
Regional terms: Goma (Spanish), Borracha (Portuguese), Kautschuk (German), Caoutchouc (French), Caucho (Spanish), Gomma (Italian)
Trade terms: Latex, Viton, Hypalon, Buna-N, Buna-S
Shelf Life & Storage
| Temp Range | Humidity | Surface Reuse | Shelf Life | Spoilage |
|---|---|---|---|---|
| 15–25 °C (away from heat) | Dry (<60%) | 20–100+ sessions | 2–5 years (natural); indefinite (synthetic) | UV/ozone degradation |
Clinical Context for Simulation
[edit source]Rubber's elastic properties closely match those of vessel walls, skin under tension, and other tissues requiring compliance and elastic recoil. The material's ability to withstand repeated stretching without permanent deformation makes it cost-effective for high-volume training.
Processing & Preparation
[edit source]Select appropriate durometer (hardness) for target tissue; softer for vessels, firmer for skin. Cut with sharp scissors or rotary cutter; rubber resists tearing when cut cleanly. Join pieces with rubber cement, contact adhesive, or cyanoacrylate. Water-based or silicone lubricants are compatible; avoid petroleum products with natural rubber.
Safety Considerations
[edit source]- Latex allergy — Screen all participants; affects 1–6% of general population, higher in healthcare workers. Have nitrile alternatives available.
- Off-gassing — New rubber may release volatile compounds; air out before use in enclosed training spaces.
- Degradation products — Aged rubber becomes brittle and may fragment; inspect regularly and replace.
