Central Venous Access (CVA) Simulator

Mixed-Reality Simulator of Central Venous Access

This turnkey, mixed-reality simulator is for practicing, learning, teaching and debriefing central venous access by the internal jugular, infraclavicular, supraclavicular and axillary approaches with and without ultrasound guidance.

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.

 

Components
