- Prepare the Training Site: Secure your anatomical training model (e.g., bone replica) on a stable surface.

Operating Instructions
Follow these steps for effective training simulations:
- Simulated Insertion: With the needle attached to the drill, position the needle tip at the desired insertion site on the training model. Activate the drill to simulate the intraosseous insertion process.
- Remove Drill: Once the simulated insertion is complete, carefully detach the trainer drill from the needle. The needle should remain in the training model.
- Remove Needle Stylet: Remove the stylet from the trainer needle, simulating the preparation for fluid administration.
- Connect Extension Set: Attach the EZ-Connect Extension Set to the hub of the trainer needle. This simulates connecting the line for fluid or medication delivery.
- Simulated Fluid Administration: Practice connecting and securing simulated fluid lines to the extension set.
- Needle Removal: After the training scenario, carefully remove the trainer needle from the training model.
- Sharps Disposal: Dispose of the trainer needle in the NeedleVise 1-Port Sharps Block provided, or an appropriate sharps container, even though it is for training purposes only.
