TissueDB/Materials/Mask, Surgical
Disposable face masks with metal nosebands are repurposed in medical simulation to create thin, flexible, suturable membrane surfaces. The mask fabric simulates tissue layers such as the diaphragm, while the metal nosebands are cut and reused as four corner attachment pieces that secure the mask under tension to a cardboard simulator frame. The material is widely available, low-cost (approximately USD 0.10–0.20 per unit retail; USD 0.20–0.40 per build for two masks), and the assembly approach is documented in the Laparoscopic Diaphragmatic Repair Simulator developed by the ALL-SAFE Consortium.
Tissues
| Tissue | Visual | Tactile | Simulator | Notes |
|---|---|---|---|---|
| Diaphragm | Partial | Partial | Laparoscopic Diaphragmatic Repair Simulator | Stretch mask flat to a rectangle. Remove the metal nosebands from 2 masks and cut each in half for 4 attachment pieces. Poke each piece through the 4 corners of the mask 1.5 cm (0.59") from the edge, push into the cardboard corrugation of the box trainer, and bend the metal back to secure. Create an approximately 50.8 mm (2 in) horizontal defect in the membrane for suture repair practice. |
Troubleshooting
Mask not taut after corner attachment. If the mask is not sufficiently taut in the vertical direction once installed in the cardboard frame, insert the two lower metal-band pieces higher up through the mask material before pushing them into the corrugation. If horizontal tension is insufficient, supplement with tape to better secure the metal bands to the cardboard.
Mask brand variation. Different mask brands have different metal nosebands. The source notes that most brands will work.

Used In Simulators
| Simulator | Purpose | Notes |
|---|---|---|
| Laparoscopic Diaphragmatic Repair Simulator | Diaphragm membrane for intracorporeal suture repair practice on a simulated penetrating diaphragmatic laceration. | Two masks per build (USD 0.20–0.40 total). Mask fabric simulates the diaphragm; metal nosebands from both masks provide four corner attachment pieces. |

Overview
[edit source]Disposable face masks repurposed for medical simulation. The mask fabric provides a thin suturable membrane and the metal nosebands serve as corner attachment pieces. Currently used in one TissueDB simulator: laparoscopic repair of traumatic diaphragmatic injury.

Clinical Context for Simulation
[edit source]Disposable face masks provide a thin, suturable, non-elastic membrane that approximates the mechanical behaviour required for laparoscopic suture practice on the diaphragm. The masks are present in clinical supply chains globally including low-resource contexts, which aligns with the Laparoscopic Diaphragmatic Repair Simulator design intent: it was developed by the ALL-SAFE Consortium (Pan-African Academy of Christian Surgeons, University of Michigan, Southern Illinois University, Soddo Christian Hospital, AIC Kijabe Hospital, Mbingo Baptist Hospital) as part of the Global Surgical Training Challenge to make trauma-surgery training buildable in any setting. The simulator targets training for occult diaphragmatic injury in penetrating thoracoabdominal trauma — an injury mechanism reported in the source documentation as having an incidence as high as 43%.
Processing & Preparation
[edit source]Prepare the mask in five steps following the source build instructions:
- Cut off the ear-loop string ends from the mask, ensuring the sections where the mask folds are glued are properly removed.
- Extend the mask by pulling on the top and bottom edges, producing a flat rectangle.
- Remove the metal nosebands from two masks.
- Cut each metal band in half, yielding four attachment pieces. Different mask brands have different metal bands; most will work.
- Poke each metal piece through one of the four corners of the mask fabric, 1.5 cm (0.59 in) from the edge, then fold the metal back on itself to lock it in place.
