OpenTibia Intraosseous Access Simulator


I created OpenTibia last year as an open-source 3d printed training device for tibial IO access. It remains free to download for all who have access to a 3D printer.

I've created this listing for those who don't have access to a printer and would still like access to an affordable training aid.

Included in the purchase will be one OpenTibia model base, and 6 replacement insertion sites. Additional replacement insertion sites can be purchased in my store. If you would like to purchase multiple models, please contact me for a discounted price.

I created this based on the need for inexpensive and easily accessible training aid for medical communities in developing countries. I currently use this for training in Haiti.

Disclosure/Disclaimer: I have no affiliation with Ez IO, or its parent company Teleflex. I have received no compensation for creating this training device. My opinions of this simulation aid are based purely on personal experience as a critical care flight paramedic. Because the suggested materials have not been tested to prove accurate representation of bone or tissue density, this model could potentially cause damage to the IO insertion needle, driver, or prove inaccurate for correct simulation. Use of this device is at your own risk, and is not meant as a replacement for proper medical training. Please follow your own local policies, guidelines, and protocols.

Special thanks to Steph Piper (sjpiper145) for creating the original anatomic model!

The model was designed to incorporate a 20ml syringe of 20.5 mm nominal diameter. Actual size and fit may vary depending on manufacturer, and accuracy of your printer and settings. **Syringe or IO Supplies Not Included**

The model is printed in two parts:
The OpenTibia base is designed to hold the smaller OpenTibia replacement site of the proximal tibial plateau. This allows for easy and inexpensive model restoration after several access attempts.

The skin is simulated with “foam” medical tape. Appoximately 4-5 layers should be sufficient to simulate the dermal layers lying superficial to the tibia.

Please contact me with any feedback or suggestions!
