Mixed Reality Simulator for Real-Time Ultrasound-Guided Caudal Block Training

Webpage created 5/20/26; verified for accessibility 5/26/26; last updated 5/20/26

This robust, turnkey, mixed-reality simulator simulates a 6-month-old infant’s lower back for practicing, learning, teaching and debriefing Caudal Block procedures with and without ultrasound guidance or assistance.

Designed for austere environments, this medical simulator does not require wireless or internet access or wet fluids and accepts 110/220V, 50–60Hz. It can be unpacked and set up by a person unfamiliar with it and be operational in 5-7 minutes.

The portable simulator fits inside a military-spec padded case with inbuilt wheels and telescoping pull-handle that meets airline checked luggage size limits (L+W+H=60”) and weighs less than 50 lbs.

The simulator adheres to SMMARTS (System of Modular, Mixed, and Augmented Reality Tracking Simulators) rapid simulator development platform specs, with quick-release placement and indexing of SMMARTS-compliant anatomies to a SMMARTS modular stand and sub-millimeter precision tracking of all tracked tools. Components include a 3D-printed physical back anatomy with bones, a virtual model of the anatomy and bones, and 6DOF-tracked instruments (20 G needle, ultrasound probe, and virtual camera) that are interoperable between SMMARTS-compliant simulators.

Features include adjustable view modes for realism, variable depth of virtual ultrasound view, two procedure difficulty levels (challenging and normal), stand rotates for right-handed or left-handed users, ultrasound-guided needling, and compatibility with real clinical ultrasound machines.

We can provide access to the simulator or copies of the simulator. Contact us for details.
