Intraosseous Trainers

Intraosseous Training Manikins

TruCorp’s infant IO training manikin TruBaby X is the most realistic and durable IO training manikin and task trainer available. Built to withstand heavy use in classrooms and simulation centers, this training model is ideal for nurses, anaesthetists and other medical professionals.

Intraosseous infusion (IO) is used to deliver fluids or medication when intravenous (IV) access is not possible. IO can also be used to collect blood samples.


TruBaby X is a complete solution for pediatric clinical skills training including IO needle insertion featuring:

  • Needle insertion site at proximal tibia, the preferred site for IO infusion in infants
  • True-to-life tibial tuberosity anatomy
  • Lifelike feel when medullary cavity is penetrated
  • Isolated pre-filled blood fluid insert provides positive feedback with correct IO needle placement
  • Blood fluid inserts can be used to practice the technique 2-3 times


TruInfant IO Leg is a durable, easy-to-use task trainer for IO practice.

TruInfant IO Leg facilitates training in IO tibial insertion and features a proximal tibia interosseous needle insertion site with accurate anatomical landmarks and realistic look and feel of simulated skin, fat and muscle tissues.

The proximal tibia is the preferred site for intraosseous infusion in infants. The TruInfant IO Leg features anatomically correct tibial tuberosity and patella anatomy which facilitates the identification of the proximal tibia intraosseous needle insertion site. Practitioners will feel realistic resistance when penetrating the medullary cavity.

This durable task trainer comes ready to use with no set-up required, and replacement IO inserts are fast and easy to change.

When establishing an intravenous line in an infant is very difficult or impossible, IO infusion is a technique used to create a non-collapsible point of entry and gain vascular access.

Long bones have marrow cavities (aka medullary cavities) made up of venous sinusoids, which are irregular blood vessel structures forming a spongy network. These sinusoids in the marrow cavity drain into a central venous canal which then drains into the main circulation system.

There are many sites containing marrow that have the potential for intraosseous infusion. In infants, the preferred site is the proximal tibia.

The absorption rate from intraosseous and intravenous access is comparable. IO access is more common in pre-hospital settings.
